Statement by the Board Chair

In 2015, CIP continued to gain ground on the strategic objectives set forth in 2014 to deliver impact at scale. CIP has the target of reaching 15 million people by the year 2020 with Orange Fleshed Sweetpotato. The Agile Potato for Asia Program is dedicated to coping with the impact on the poor of climate change coupled with high population density and land degradation. Significant inroads have been made in developing fast-maturing disease resistant varieties that provide flexible planting and harvesting times without putting undue pressure on dwindling land and water resources. The seed potato for Africa projects are on track to reaching CIP’s goal of 600,000 smallholder farmers in potato growing regions of Africa with high-quality seed.

Financial Performance

Despite a successful fundraising of Window 3 and Bilateral funds, CIP saw a reduction in total revenues in 2015 driven by the shortfall of funds from Windows 1 and 2 of the CGIAR Fund as compared to 2014. Total Revenue reported in 2015 was $58.5M, including $26.3M from Windows 1 and 2. The revenue in Windows 1 and 2 represent a decrease of $13.1M when compared to 2014. CIP’s Operating Expenses in 2015 are $60.4M and represent a reduction of $10.1M from 2014.

The short-term solvency indicator (liquidity), which measures the number of days of working capital to fund expenditures excluding depreciation, was 108 days as of December 31, 2015. While the long-term financial stability indicator (adequacy of reserves), which measures the number of days of unrestricted net assets, was 92 days (both of these indicators are within the CGIAR recommended norms). The indirect cost ratio of the Center was 15% for 2015. The ratio has been calculated following the Financial Guidelines No. 5, and expresses the relation between direct and indirect costs.

CIP’s financial indicators reflect that the Center is maintaining its financial health, though no institution is immune to financial or operational risk. To mitigate risk, the Board’s Audit Committee ensures oversight of CIP’s risk management policies and plans. In a much broader sense, the Board oversees Center operations in the interest of donors and stakeholders.

Leading role in Root, Tubers and Bananas CGIAR Research Program (CRP)

CIP continues its lead role in implementing the CGIAR Research Program on Roots, Tubers and Bananas joined by three other CGIAR partner centers: International Center for Tropical Agriculture (CIAT), International Institute for Tropical Agriculture (IITA), and Bioversity International, plus The Agricultural Research for Development Center (CIRAD). CIP is also working in a total of 7 other CRPs including: Agriculture for Nutrition and Health, Climate Change, Agriculture, and Food Security, Dryland Systems, Managing and Sustaining Crop Collections, Integrated System for the Humid Tropics, Policies and Institutions and Markets, and Water, Land and Ecosystems. Involvement in these CGIAR Research Programs allows CIP to expand its research programs to continue playing an important role in improving potato and sweetpotato production systems and the livelihoods of millions of people around the world.

Appreciation

I would like to express my gratitude and appreciation to Dr. Simon Best and Dr. Bir Pal Singh who finished their terms on the Board in 2015, and who served with dedication and high standards during their tenure as Board members.

On behalf of the Board, I would like to thank CIP’s donors, investors, and all CGIAR partners for their support. I also extend my appreciation to CIP’s management and staff for their continued dedication to the organization and its important mission.

With Appreciation,

Dr. Rodney Cooke

Director General’s Foreword

In September 2015 the United Nations General Assembly formally announced the Sustainable Development Goals (SDGs) as a new universal set of goals, targets and indicators for UN member states to frame their agendas over the next 15 years. For CIP, the SDGs align positively with our mission and represent a way for us to align our work for the next 15 years.

As an agriculture research for development organization, CIP’s work is consistent with 11 of the 17 SDGs and of those 11, our work is perfectly aligned with the SDGs of Ending Poverty, Eliminating Hunger, Gender Equality, Climate Action, and Life on Land. This 2015 Annual Report tells the story of CIP’s alignment with the SDGs and the impact that we have had already in doing so.

We have made progress toward achieving impact at scale on the ground across the continents where we work. In the past year CIP has seen advancements in the importance of quality seed in South America and Africa. In Ecuador, the National Agriculture Research Institute has begun producing tons of seed potatoes to ensure the quality and yield of the country’s potato harvest. They have set a goal of increasing the supply of quality seed by more than 600% by 2018. In Sub-Saharan Africa, CIP coordinated a seed systems community of practice for sweetpotato that allows scientists to share knowledge and best practices. These are just two efforts to ensure quality seed systems but are fantastic examples of how progress can be made at the both the grassroot and grasstop levels to have an impact.

2015 also marked a positive year for upstream research having an impact in the field. In promising research coming out of Uganda, CIP has seen positive results from confined field trials with late blight resistant potatoes using transgenic events with the 3 R genes in two popular potato varieties. Attaining durable late blight resistance has been a goal of potato research for decades and initial results from 2015 indicate that we are close to overcoming it.

We have been particularly honored by the interest and support for CIP’s sweetpotato initiatives shown by Nane Annan and Kofi Annan, former UN General Secretary. Collectively the Annan’s have been advocating for orange fleshed sweetpotato cultivation in Ghana in hopes of replicating the successes of CIP’s orange fleshed sweetpotato initiatives elsewhere in Africa in reducing child blindness due to Vitamin A deficiency. Through their advocacy for this star of the biofortification movement, we expect sweetpotato to grow in importance in Ghana and further scale out our Resilient Nutritious Sweetpotato program to this important country in Sub-Saharan Africa.

I am proud of CIP’s work and the contributions that we, along with many partners, make toward ending poverty, eliminating hunger, ensuring gender equity, combating climate change, and improving our environment. It is through our partners and donors that we are able to have an impact and for this I am thankful.

Gratefully yours,

Barbara H. Wells
Director General

Our Crops

Potato

When boiled, a single medium-sized potato contains about half the daily adult requirement of vitamin C and significant amounts of vitamin B, iron, potassium, and zinc.
Potato produces more food per unit of water than any other major crop.
Potato can grow in almost any climate, from sea level to 4,700 meters above sea level.
There are about 5,000 different varieties of potato, most of which are found only in the Andes.
More than a billion people worldwide eat potato.
China is the world’s largest producer, harvesting more than 73 million tons of potato a year.
Grown in about 130 countries, potato is the third most important food crop after rice and wheat (1 ha of potato can yield two to four times the food value of grain crops).

SweetPotato

Just 125 g of fresh orange-fleshed sweetpotato root contains enough beta carotene to provide the daily vitamin A needs of a preschool-aged child. The crop is also a valuable source of vitamins B, C, and E.
Sweetpotato is also a healthy, cheap animal feed. Studies suggest that livestock fed on sweetpotato vines produce less methane, meaning its use could potentially mitigate global warming.
More than 105 million tons are produced globally each year, with 95% in developing countries.
Worldwide, sweetpotato is the sixth most important food crop after rice, wheat, potatoes, maize, and cassava, but it ranks fifth in developing countries.
Sweetpotato can grow at altitudes from sea level to 2,500 meters above sea level, and comes in varieties ranging in color from white to yellow to orange to purple.
Sweetpotato is a storage root, not a tuber like the potato.

Kofi and Nane Annan Join CIP and Partners in
Promoting Orange-Fleshed Sweetpotato in Ghana

CIP gained two important allies in 2015 – former Secretary-General of the United Nations Kofi Annan and his wife, Nane – whose advocacy is boosting efforts to reduce hunger, malnutrition, and poverty in Ghana through the cultivation and consumption of orange-fleshed sweetpotato (OFSP), clearly in line to contribute to SDGs.

Mr. and Mrs. Annan attended a roundtable discussion with representatives of CIP and approximately 30 active and potential partners at the Council for Scientific and Industrial Research’s (CSIR) Crops Research Institute, in Kumasi, Ghana in March 2015. They participated in a field trip to see sweetpotato trials at the CSIR-Savanna Agricultural Research Institute, in Tamale, in August 2015. The field visit was followed by a luncheon featuring various OFSP dishes, displays on the work of CIP and partners, and a discussion with local partners about a strategy to scale up the adoption of OFSP in the country.

CIP Leads Initiative to Understand how Climate Change Affects Pests

The Paris Agreement of December 2015 heralds a greater global effort to reduce greenhouse gas emissions and mitigate the effects of climate change, yet farmers around the world are already dealing with the consequences of a warming atmosphere. While more frequent droughts and floods are causing widespread crop damage, the greatest threat to farmers from global warming may be the growing abundance and expanding distribution of crop pests and diseases.

“A crop pest that currently produces three or four generations per year may produce as many as six or seven generations per year once average temperatures rise by 2ºC—3ºC,” warned Jürgen Kroschel, Team Leader for Agroecology and Integrated Pest Management at the International Potato Center (CIP).

Pests and diseases already pose major threats to the food security and livelihoods of smallholders in developing countries, yet there is a shortage of information about how much and where climate change will transform those threats. To help fill that knowledge gap, Kroschel is coordinating a CIP-led, multi-crop collaboration with several other international research centers and national programs to conduct research aiming at predicting how global warming will affect some of the most destructive crop pests and diseases in East Africa. The research project’s ultimate goal is to help local government agencies and the farmers they serve to better assess, prepare for, and confront the risk of crop pests and diseases as the climate changes.

Funded by the CGIAR Research Program on Roots, Tubers and Bananas (RTB), the research focuses on the critical pests and diseases affecting potato, sweetpotato, banana and cassava in Africa’s Great Lakes Region. It combines the expertise of researchers from CIP, Bioversity International, the International Center for Tropical Agriculture (CIAT), the International Institute of Tropical Agriculture (IITA), the UK’s Food and Environment Research Agency (Fera) and Commonwealth Agriculture Bureau (CABI), US universities and national programs in the region. Some of the tools those researchers are using include the Insect Life Cycle Modeling (ILCYM), which was developed during a prior CIP project to model the impact of climate change on insect pests in Africa, which was funded by the German Federal Ministry of Economic Cooperation and Development (BMZ).

Researchers have been working both in the laboratory and in the field, namely the Ruhengeri area of Rwanda and Burundi’s Rusizi Valley, both of which have a wide diversity of farming systems along an altitudinal gradient, and where banana, cassava, potato and sweetpotato are widely grown. CIP, Bioversity, IITA and national partners began there by coordinating a socioeconomic baseline survey of more than 400 farm households in the two countries, and installing networks of weather stations at different altitudes to provide a regional climatic database. The researchers are studying farms at different altitudes to better understand the role that altitude plays in pest distribution and intensity as the temperature rises.

“We are studying the impacts of climate change not only on pests and diseases, but also on the livelihoods of farmers in these areas,” said Kroschel.

At the same time, scientists at CIP, Bioversity, CIAT, and IITA have conducted laboratory research to better understand how rising temperatures affect the development of specific pests – data that are being used to predict how climate change will increase the risk they pose. To do this, researchers use ILCYM software.

“You need individual assessments for each species to predict changes under rising temperatures. You can’t generalize,” explained Kroschel.

Thanks to the RTB initiative, the ILCYM software that CIP developed using potato pests is now being applied to insects that attack various other crops. Kroschel added that researchers are also trying to determine how climate change will affect the transmission of viruses by insects that serve as vectors for crop diseases.

An important project goal is to facilitate and improve risk assessments for the most critical insect pests and pathogens, which will help the region’s governments, non-governmental organizations and the private sector to confront those threats. The participating research centers are working with national programs in several East African countries to strengthen pest surveillance and the capacity to elaborate and act upon pest risk analysis (PRA) documents, which can be an important tool in national or regional efforts to help farmers prepare for pest risks.

CIP prepared a PRA document for the tomato/potato leaf miner (Tuta absoluta) that was used and further adapted during a training course for officials from Burundi, DR Congo, Uganda, and Rwanda in October 2015. The preparation of PRA documents for several cassava and banana diseases is underway, led by IITA and Fera. Kroschel noted that this project complements efforts by the Food and Agriculture Organization of the United Nations (FAO) to promote the production and use of PRA documents by African ministries of agriculture.

While the threat that pests and diseases pose to crops is bound to grow under climate change, the good news is that there is a concerted effort underway to help farmers in East Africa to prepare for it.

CIP Participates in 2015 World Potato Congress and Planning for 2018

CIP has played an increasingly prominent role in the World Potato Congress (WPC): the world’s largest gathering of potato experts and industry representatives. Not only did CIP leadership give presentations at the 9th World Potato Congress (WPC), held in Beijing, China in July of 2015, but the Center was also closely involved in a Peruvian Government campaign that convinced WPC organizers to hold the next congress in Peru.

The triennial WPC brings together hundreds of potato scientists and representatives of government, agriculture and food industries from at least two dozen countries for several days of speeches, exhibitions and networking. It is held at a different venue each time, and is organized by the non-profit World Potato Congress Inc., founded in 1993.

The 9th WPC took place July 28-30 in the Badaling International Convention Center, in Yanqing District, on the outskirts of Beijing. It was held in conjunction with several other events focused on potato, which together attracted thousands of participants.

CIP representatives played prominent roles in the WPC and related events. Director General Barbara Wells gave a keynote speech on the role of potato in global food security, and delivered the opening address for the International Workshop on Potato-Derived Staple Food Products and Industry Development. CIP Board Chairman Rodney Cook chaired a WPC keynote session, while CIP’s Deputy Director General for Research and Development, Oscar Ortiz, gave a speech on potato diversity and utilization in Peru. Lu Xiaoping, Director of the CIP-China Center for Asia Pacific (CCCAP), and several other CCCAP scientists also participated in the congress.

In her keynote speech, Wells noted that: “The world is producing and consuming potatoes more than ever before. The opportunities to provide pro‐poor varieties and technologies where potato already exists are clear.” She then challenged attendees to work together to “Connect the dots between what you do and these opportunities. No matter what your role in the industry is, there is a place for you to contribute to food security around the world.”

CIP will have ample opportunity to showcase its work to strengthen food security and incomes with potato when Peru hosts the 10th WPC in 2018. Personnel at CIP headquarters in Lima, Peru, worked closely with representatives of Peru’s National Institute for Agricultural Innovation (INIA) and other institutions to convince WPC leadership to choose Peru to host the next congress, and CIP will participate in a committee that helps to organization the event. This is the first time that the WPC will take place in South America.

The 10th WPC will be held in Cusco, the former capital of the Incan empire, perched high in the Andes in a region where people have been growing potatoes for thousands of years. CIP researcher Miguel Ordinola, who worked with INIA on the campaign to get the WPC to come to Peru, explained that the country’s selling points included the fact that it lies within the most important center of origin of the potato and houses the world’s greatest potato biodiversity, with approximately 3,000 native varieties.

“The genes and genetic diversity of those native potatoes could hold solutions for many of the problems that potato farmers face around the world,” said Ordinola.

Decades of Collaboration lay the Foundation for CIP-China Research Center

For more than 35 years, CIP has collaborated with Chinese universities (notably the Chinese Academy of Agricultural Sciences) and national institutions to build research capacity and improve potato and sweetpotato farming in the world’s most populous nation. During that time, CIP researchers have contributed to the steady expansion of root and tuber production in China, which is now the world’s top potato producer.

In the coming years, this collaboration in agricultural research for development will be greatly enhanced thanks to the Chinese government’s commitment to build a new research campus for the CIP-China Center for Asia and the Pacific (CCCAP), which was registered in China as an Inter-Governmental Organization in 2014. Construction workers have already made major progress on the CCCAP campus, located in Yanqing District, on the outskirts of Beijing.

The commitment to build this sizeable research facility is a reflection of China’s desire to tap the full potential of potato and sweetpotato for improving food security, health, and incomes. It is also a testament to the impact of CIP’s collaboration with the Government of China over the past four decades.

Since 1978, CIP has contributed to the development of research capacity, new potato varieties, and potato and sweetpotato technologies in China, such as virus-free planting material, which have, in turn, resulted in significant improvements for Chinese farmers and consumers. CIP has completed more than 50 root and tuber research projects in China, contributing to the development of new varieties, better farming practices and machinery, postharvest storage and processing technologies. During that time, China has imported more than 8,000 root and tuber accessions from CIP, and Chinese scientists have bred more than 100 new varieties with ‘CIP parentage,’ some of which are widely cultivated and have significantly boosted yields. From 1978 to 2012, average potato yield in China rose by 24.5%, whereas sweetpotato yield increased by 54.2%.

At the same time, CIP has received university degree programs, visiting scholars, short-term training for research personnel and field training for extension agents, thereby helping China to build the capacity needed to improve root and tuber production and utilization. In 2008, when China’s Ministry of Agriculture established national potato and sweetpotato research systems, researchers who had worked with or been sponsored by CIP were tapped for leadership positions. Among the 24 leading scientists appointed to the national potato research system, 11 had worked on CIP projects and six had been sponsored by CIP to study abroad. Of the 16 leading scientists appointed to the national sweetpotato research system, ten had worked on CIP projects and six had been sponsored by CIP to study abroad.

This long-term partnership will continue to produce positive results in China and beyond. Once completed, the CCCAP campus will be a fully integrated, modern agricultural research center that offers the potential to become a growth platform for CIP. Researchers from various countries will collaborate there on efforts to improve root and tuber crop production in China, East Asia and the Pacific. Research at CCCAP will include various root and tuber crops, and scientists from other international centers can also be hosted here; the center will promote technical exchanges and other cooperation, joint research, and extension services for an international impact.

Conserving and Tapping Potato and Sweetpotato Crop Wild Relatives to Help Agriculture Adapt to Climate Change

CIP scientists have joined colleagues at other research institutions in efforts to improve the conservation and study of wild potato and sweetpotato relatives, and to tap their genetic diversity for improving cultivated potatoes and sweetpotatoes. The results, particularly in terms of understanding genetic diversity and suitable traits, could help feed the world as climate change makes it harder for smallholders in many areas to grow crops.

The research is part of a decade-long, global initiative called ‘Adapting agriculture to climate change: collecting, protecting and preparing crop wild relatives,’ which is funded by the government of Norway and coordinated by The Global Crop Diversity Trust with the Royal Botanic Gardens, Kew. The project aims to strengthen the conservation of crop wild relatives (CWR) – wild plant species that are closely related to cultivated crops – and to help breeders tap their genetic diversity for the development of more resilient crop varieties.

“Crop wild relatives have evolved in their native habitats, coming to be adapted to specific conditions such as high temperatures, salinity, pests and diseases,” explained Nora Castañeda-Álvarez, a scientist at the International Center for Tropical Agriculture (CIAT), which CIP has partnered with on the CWR project and other initiatives. “Such traits can be bred into crop plants, greatly benefiting agricultural production, but this is only possible if these germplasm resources are made available to breeders.”

CIP has long been involved in the study and conservation of potato and sweetpotato CWR and the CIP Genebank preserves hundreds of CWR accessions, but its involvement in the global project has enhanced those efforts. The CWR project began with gap analyses for an array of crops to assess how well that biodiversity is conserved ex situ (in genebanks), and to identify species and areas in need of field collection. With support from the CGIAR Research Program for Roots, Tubers and Bananas (RTB), CIP researchers collaborated with scientists at CIAT, the U.S. Department of Agriculture, and universities in the Netherlands, the U.K. and the United States on gap analyses for potato and sweetpotato CWR, the results of which were published in 2015.

In the article “Ex Situ Conservation Priorities for the Wild Relatives of Potato (Solanum L. Section Petota),” [http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0122599#authcontrib] published in PLOS ONE, the authors assigned 32 of the 73 closest potato wild relatives high priority status for further field collection, because they are under-represented in ex situ collections. They noted that there is an urgent need to collect samples of four CWR species that are completely absent from genebanks: S. ayacuchense, S. olmosense, and S. salasianum from Peru, and S. neovavilovii from Bolivia.

Peru, which is one of the most important centers of potato diversity, has a large number of CWR species. But according to CIP consultant Alberto Salas, who has spent decades studying and collecting potato CWR, many of them are threatened in the field. He explained that the expansion of communities and road construction have destroyed the habitat of rare CWR species, citing several species that have disappeared from areas where he once collected them.

Scientists from CIAT, CIP, USDA and several universities who collaborated on the sweetpotato CWR gap analysis encountered a comparable situation. They determined that 78.6% of the closest wild relatives of sweetpotato are high priorities for further collection. The researchers identified Central and Southern Mexico and the Southeastern United States as sweetpotato CWR biodiversity hotspots where collection should be prioritized.

“Unfortunately, it is in these ‘hotspots’ of great genetic diversity that the risk of losing it is particularly high,” said CIP associate scientist Bettina Heider. “The research on CWR has confirmed that not only do we have few sweetpotato CWR genetic resources in genebanks and herbariums, but the formal conservation of in situ resources (in the wild) is also very limited.”

Heider is one of 17 researchers who revised the taxonomic and geographic information on sweetpotato CWR, modeled their distributions, determined their availability to crop breeders, and explored their adaptations to climatic and soil stresses in order to identify species that could be useful for breeding more resilient sweetpotato varieties. The results of their research were published in the journal Frontiers in Plant Science under the title “Distributions, ex situ conservation priorities and genetic resource potential of crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas],” (http://journal.frontiersin.org/article/10.3389/fpls.2015.00251/abstract)

“We specifically looked for drought- and heat-tolerance, which are major issues in Sub-Saharan Africa and also increase vulnerability to major pest incidence in the region,” said CIAT scientist Colin Khoury, the study’s lead author, “We found that a number of these species, such as Ipomoea littoralis, I. trifida, I. splendor-sylvae, I. leucantha, I. triloba, and wild I. batatas were potentially distributed in regions with low precipitation and high heat, well beyond the comfortable range of cultivated sweetpotato.”

Identifying CWR species with useful traits is an important step toward using them to improve crops, but genetic differences can make it difficult to cross wild species with their domesticated relatives. Such crosses often require a slow process of pre-breeding to make the CWR compatible with the crop species.

The global CWR project is supporting efforts to collect under-represented CWR species in the field and to develop pre-bred CWR materials with traits of importance for crops. In September 2015, Crop Trust scientist and CWR project manager Hannes Dempewolf traveled to Peru to see potato and sweetpotato CWR pre-breeding trials. He traveled to CIP research stations in Huancayo and San Ramón – in the Andes and Amazonian Highlands – where CIP is conducting CWR research.

While CIP has made progress toward introducing CWR resistance to the late blight and bacterial wilt diseases into its potato breeding lines, use of CWR species to improve sweetpotato is more incipient. With support from The Crop Trust, CIP is working with seven of the 14 CWR species in the Ipomoea batatas series Batatas to develop hybrids with useful traits such as drought- or heat-tolerance for use in sweetpotato improvement. “We are trying to get a mind change in breeding communities to think of wild relatives as an important source of genetic material to adapt crops to changing climatic conditions,” Dempewolf said.

CIP researchers hope that their work with CWR will contribute to breeding potato and sweetpotato varieties that produce well in harsh environments. This could be a boon for farmers in Africa and Asia as they struggle to produce enough food on an increasingly hot and crowded planet.

Strengthening Seed Systems to Spread Sweetpotato’s Benefits

Strengthening Seed Systems to Spread Sweetpotato’s Benefits

Beyene Demstu is a researcher based at the Mekele Agricultural Research Institute, Tigray Region, in northern Ethiopia. For much of his 20-year career, he has focused on the use of biotechnology and tissue culture to accelerate the breeding of highland legumes, wheat and barley, but in 2012, he began working with sweetpotato. He is now convinced of the value of promoting sweetpotato, especially vitamin A-rich, orange-fleshed varieties.

“Sweetpotato is very new to my region but it has a very big potential. Malnutrition of children under five years is 30-40% and most of it is vitamin A deficiency. With sweetpotato, you can feed the children and improve their nutrition status,” Demstu said.

Sweetpotato is an important food security crop in much of Sub-Saharan Africa (SSA), and orange-fleshed sweetpotato (OFSP) is a vital source of beta-carotene, which is converted into vitamin A in the body. OFSP can thus prevent the blindness, disease, and premature death that commonly result from vitamin A deficiency in SSA. But the crop’s potential is often diminished by a lack of sufficient and timely access to disease-free, or ‘clean,’ planting material.

The quickest way to grow sweetpotato is to plant vine cuttings, but preserving vines or the roots they sprout from until the next planting cycle can be a major challenge for smallholders in SSA, especially in regions with long dry seasons. Once vines are planted, the plants are commonly attacked by whiteflies and aphids, which serve as vectors for sweetpotato viruses. Those viruses accumulate from one planting cycle to the next, significantly reducing yields.

In an effort to strengthen the research and development interventions to help farmers deal with such challenges, and facilitate the dissemination of quality planting material, CIP has coordinated the creation of a ‘seed systems community of practice’ for sweetpotato in SSA.

Demtsu is an active member of that community of practice (CoP), and is collaborating with CIP to do research on methods to increase the multiplication rate of sweetpotato, so that there is more clean seed to reach more households. “All I do is to try and assist farmers to get clean planting material.”

The seed system CoP was officially launched in April 2014 at a meeting of approximately 40 specialists from across Africa held in Entebbe, Uganda. By the end of 2015, the CoP had grown to include 120 members from SSA, Europe, USA, and Peru, most of whom participate virtually, via a Google discussion group. Meetings have also been held in Kigali, Rwanda in May 2015 and in Nairobi, Kenya in December 2015.

The CoP allows scientists to exchange knowledge and experiences of challenges and lessons related to sweetpotato seed systems. Demstu explained that he has already gained useful knowledge of biotechnology and sweetpotato from colleagues in the community. “I do not have to reinvent the wheel; I just listen and learn from those who have more experience and knowledge,” he said.

CIP organized the CoP under the Sweetpotato for Profit and Health Initiative: a 10-year, multi-donor initiative that seeks to reduce child malnutrition and improve smallholder incomes through the effective production and expanded use of sweetpotato. This initiative is a partnership mechanism of CIP’s Resilient Nutritious Sweetpotato Program. The CoP was initiated with funding from the Bill & Melinda Gates Foundation, but many organizations are now involved in it, including national institutions, NGOs, and the private sector.

One of the major challenges that participating scientists are working on is how to ensure the survival of planting material in areas with extended dry periods. A root-based vine multiplication system called Triple S (Sand, Storage and Sprouting) is being tested and promoted in Uganda, Tanzania, and Ethiopia. Normally, it is the task of women farmers to keep a small plot of sweetpotato irrigated through the dry season to ensure the survival of vines for planting in the next season. With the Triple S system, farmers store small roots in sand during the dry season and then plant them in seedbeds six to eight weeks before the rains are expected. Once they are watered in the seedbed, the roots will sprout and provide cuttings to plant when the rains begin.

When new technologies such as Triple S are tested and validated, researchers specifically look at the resources they require, who has those resources, and what specific factors could assist or hinder their uptake by different types of farmers, including youth and women. For Triple S in particular, women in Tanzania commented that they liked it because they could be confident that they would have planting material, and know exactly when they would have it, rather than having to look for it when the rainy season begins.

Another major challenge is protecting healthy plants from the whiteflies and aphids that are responsible for spreading sweetpotato virus diseases. A low-cost net tunnel technology has been developed and promoted among vine multipliers who sell sweetpotato planting material to farmers. This technology has been implemented successfully in Rwanda’s Rulindo and Kamonyi Districts, which CoP members visited following the meeting in Kigali in April 2015.

The Kigali meeting was opened by Dr. Jean Jacques Muhinda, Director General of the Rwanda Agriculture Board. He commended the researchers from his institution, the other national sweetpotato programs, NGOs, and CIP for their work on developing a clean seed system for sweetpotato. “I urge you to benefit from this annual consultation and I trust that you will take back ideas to your own country communities to test and put into practice for the benefit of sweetpotato farmers across Sub-Saharan Africa,” he said.

This kind of encouragement, commitment, and support from the public and private sectors will be critical in the development of effective sweetpotato seed systems. For members of the CoP, such collaboration not only helps to drive up demand, it also facilitates the implementation of effective delivery channels that will put clean seed in the hands of farmers when they require it.

Quality Seed: the Basis of Better Potato and Sweetpotato Production

Creating viable systems for multiplying and distributing potato and sweetpotato seed in developing countries is vital for getting improved varieties out to farmers, and to help increase their yields. Because potato is propagated by planting tubers, and sweetpotato by planting vine cuttings, there are problems associated with planting material – commonly called seed – that can become major constraints for smallholders. Compared to true seed, sweetpotato vines and seed potatoes are perishable, creating storage challenges, and their multiplication rates are low. There is also a high risk of viruses accumulating in plants and passing from one planting cycle to the next via seed, which can result in major yield losses over time. Studying the factors involved in seed degeneration of vegetatively propagated crops has been a priority of CIP as part of research sponsored by the RTB program. Understanding these factors helps to design technologies and approaches to slow down degeneration and maintain seed quality for more cropping seasons, which benefits farmers directly.

CIP has developed successful technologies for producing and multiplying disease-free planting material that have been transferred to developing nations. It works with partners to design seed systems that are appropriate for local conditions, and that allow smallholders to participate in, and benefit from, the dissemination of improved varieties. CIP also promotes training in on-farm practices such as positive selection, which allow farmers to limit the negative impact of pathogens. Seed systems play an important role in CIP’s efforts to tap the full potential of potato and sweetpotato to improve food security, diets, and incomes around the world.

Ecuador Launches National Effort to Improve Potato Production

In a massive greenhouse near Sangolquí, southeast of the Ecuadorian capital of Quito, the National Agricultural Research Institute (INIAP) is producing tons of seed potatoes using aeroponics and other rapid propagation technologies. That greenhouse is the epicenter of an ambitious government effort to improve potato production by expanding farmer access to certified, disease-free seed. The idea for this innovative undertaking grew out of a training course that CIP and INIAP organized several years ago, and CIP has continued to provide technical backstopping and other support as the government develops a strategy to boost potato production across Ecuador.

Most of the approximately 85,000 farmers who grow potato in that Andean nation are smallholders who own less than five hectares of land. Ecuador’s average potato yield is well below that of neighboring countries – 9 tons/hectare compared to 14 t/ha in Peru and 19 t/ha in Colombia. According to Javier Jiménez, INIAP’s Director of Technology Transfer, a major cause of this gap is that Ecuadorian farmers commonly plant seed potatoes that are contaminated with pathogens, which decrease yield and potato quality.

Jiménez explained that although the Ministry of Agriculture, Livestock, Aquaculture and Fishing (MAGAP) has had a program for certifying disease-free seed potato in place for decades, the vast majority of farmers continue to purchase seed potatoes in informal markets or save part of each potato harvest for planting. He noted that farmers often use the smallest potatoes for seed, because they are worth less on the market, but those potatoes are usually infected with pathogens that will compromise their next harvest.

“The challenge on a national level is to be able to offer quality seed in a timely manner and in the quantities that the country’s farmers require,” said Jiménez.

To meet this challenge, the government has set a goal of increasing the supply of certified seed by more than 600% in order to expand the area planted with disease-free seed to 15,000 ha – approximately 30% of the area dedicated to potato in Ecuador – by 2018. Crop scientists expect that this will increase potato yield by 25%.

Jiménez explained that INIAP has collaborated with CIP on the development of a two-pronged approach to reaching these goals: ramping up the supply of certified seed potato using the latest rapid propagation technologies, while helping MAGAP extension officers teach farmers ‘positive selection’ – an on-farm method for selecting healthy potatoes to use as seed in the next planting cycle.

“Given what a major constraint low quality seed is for Ecuador’s farmers, it’s a relief to see the government prioritize potato and invest heavily in an integrated approach to improve farmers’ seed quality,” said Peter Kromann, CIP scientist based in Ecuador.

Kromann explained that the idea for the initiative was born during a CIP-INIAP course on aeroponic systems held between 2011 and 2012, but it has become a reality thanks to a major commitment by the government. Ecuador’s President Rafael Correa signed an executive decree last year calling for a vast increase in the amount of land planted with certified seed potato, and he inaugurated the INIAP aeroponic greenhouse last July.

CIP has been testing and promoting aeroponics – a system for propagating plants in chambers bathed in a mist of water and fertilizers – for potato since 2006, and introduced the technology in Ecuador in 2008. Aeroponic systems can produce more potatoes faster than planting seeds in the ground, and they make it easier to ensure that the resulting tubers are disease free. CIP has consequently promoted the use of aeroponics for potato seed in ten countries to date.

Jiménez explained that most of INIAP’s 2.2-hectare greenhouse in Sangolquí is dedicated to aeroponics, but potato seed is also being produced there using hydroponics and by planting sections of vines from disease-free mother plants. By early 2015, INIAP had produced 22 tons of seed potatoes using aeroponics and other rapid propagation methods, but that seed needed to be multiplied in the ground in order to produce enough certified seed to supply all the farmers that the MAGAP aims to reach. INIAP works with a network of 16 certified seed multipliers – private farms, farmer associations, and public institutions – that have undergone training and are registered with MAGAP and which sell the seed they produce to the ministry for distribution.

“We have worked with CIP in the design of a system for getting the seed we produce in the greenhouse to the farmer,” said Jiménez.

One of the most experienced seed multipliers in the network is a consortium of farmer associations called CONPAPA, which was founded more than a decade ago with support from CIP and INIAP. Luis Montesdeoca, the administrator of the CONPAPA branch in the province of Tungurahua, explained that 13 of the group’s 70 active members are certified potato seed multipliers. They sell the seed they produce to CONPAPA, which in turn sells to its members and MAGAP. Since CONPAPA has been multiplying and distributing clean seed to members for eight years, those farmers provide an example of the importance of clean seed; they produce an average of 14-15 tons/ha, compared to the national average of 9 tons/ha.

“We have improved productivity in every sense: we are producing greater quantities of potato, we have greater control and, primarily, we’ve eliminated the mixing of varieties, which was a big problem,” said Montesdeoca. He explained that the ability to produce a consistent quality of potato allows CONPAPA to supply processors of frozen french fries for restaurants, which pays better than fresh potato markets. With help from CIP, some CONPAPA members are now producing native potato varieties for a company that produces gourmet potato chips, which pays an even higher, fixed price.

In hopes of producing more such success stories across Ecuador, CIP and INIAP have collaborated on the development of a curriculum to help MAGAP extensionists train farmers in the multiplication of seed and the selection of healthy seed potatoes from their harvests, and are working with MAGAP on a strategy for scaling out the multiplication and distribution of certified seed.

“If INIAP reaches its goals, the country will be able to increase its potato production, food security, and farmer income,” said Kromann. “This initiative could serve as an example that inspires increased governmental investment in potato in other countries.”

“CIP has played an important role in the design of the strategy; CIP colleagues have accompanied us in meetings with the minister or other actors, and they are helping us to design the structure of a system for the production and use of potato seed,” observed Jiménez. “I think the experience that CIP has shared with us, and the advice and recommendations have helped us a lot.”

Helping Farmers in Central Asia Produce Potatoes in Intense Heat and Drought Conditions

Potato is an important staple in the Central Asian nations of Tajikistan and Uzbekistan, yet farmers in many parts of these countries face challenges from extreme summer heat, soil salinity, and competition for water. This situation is expected to be worsen in the future as climate change intensifies the hot, dry conditions of the Aral Sea Basin, where diminishing rainfall and growing irrigation demand are expected to leave lowland regions with 30% less water for crops. CIP has consequently worked with local partners to develop early maturing, drought- and heat-tolerant potatoes that are adapted to local conditions, and the recent release of various new varieties bodes well for the future of potato production in this region.

As part of the Agile Potato for Asia Program, CIP has collaborated with national partners in Tajikistan and Uzbekistan on the development of potato varieties that produce well under extreme heat and water stress, while transferring and testing technologies to enhance on-farm water management, with support from Germany’s Federal Ministry of Economic Cooperation and Development (BMZ). In collaboration with the International Water Management Institute, Hohenheim University, the Scientific Research Institute of Vegetable, Melon and Potato Crops and the Institute of Bioorganic Chemistry (Academy of Sciences) in Uzbekistan, and the Institute of Horticulture and Vegetable Growing (Academy of Agricultural Sciences) in Tajikistan, CIP has coordinated the development of new agile potato varieties, and the validation and dissemination of tools to help farmers use irrigation water more efficiently.

At the same time, this research has improved knowledge of how potato plants respond to drought stress, the effects of different irrigation regimes on tuber production, and the presence of drought and heat tolerance within CIP’s potato breeding populations. This helped scientists identify the best CIP clones for breeding programs, develop decision-support tools for farmers facing water scarcity, and test new technologies for monitoring field trials and predicting which crosses are likely to have high levels of heat- and drought-tolerance.

The project resulted in the registration of seven CIP-bred potato varieties for release and distribution to farmers by national partners in Tajikistan and Uzbekistan. After identifying candidates within its breeding pool, CIP coordinated field trials for 31 virus-resistant, drought- and heat-tolerant clones, most of which produced well under the region’s challenging environmental conditions. However, according to Rusudan Mdivani, CIP’s Regional Liaison for Central Asia and the Caucuses, subsequent cooking and taste tests revealed that some of these clones had a bitter taste, which may be caused by the accumulation of glycoalkaloids in tubers caused, in turn, by the intense heat of the region’s long summer days. CIP researchers are trying to develop an inexpensive test to detect which clones accumulate glycoalkaloids under heat stress in order to remove those parents from breeding populations.

Seven of the CIP-bred varieties that performed well under local summer conditions and produced potatoes with good flavor and cooking qualities were registered for release in Tajikistan and Uzbekistan. These varieties not only tolerate extreme heat, water stress, and soil salinity, but they also produce tubers within 90 days and are resistant to viruses that can significantly reduce potato yields in the region. CIP researcher Timur Abdurakhmanov explained that the region’s farmers typically plant seed potatoes imported from other countries, which are susceptible to the accumulation of viruses that reduce the yields of subsequent planting cycles, forcing farmers to buy new seed every year. However, with the CIP-bred, virus-resistant varieties, farmers can save part of their harvest to use as seed the following year, which represents significant cost savings and reduces the risk of crop loss.

While breeding potatoes that are adapted to the Aral Sea Basin, CIP shared potato seed production technology with project partners, in order to help them get new varieties out to farmers and develop an alternative to imported seed. Uzbekistan’s Institute of Bioorganic Chemistry has the capacity to produce up to 2 million in vitro plants per year, and produced 115 tons of seed potatoes of the varieties Sarnav (CIP 397077.16) and Pskom (CIP 390478.9) in 2015. This seed will be multiplied in 2016 and distributed to farmers in three regions of Uzbekistan who will use it to grow and sell seed potatoes. Abdurakhmanov observed that Sarnav is an especially good alternative to the imported varieties that are widely grown in the country.

Another variety that has great potential for the region is Tajikiston (CIP 392797.22), one of four CIP-bred potato varieties released in Tajikistan in recent years. Approximately 500 smallholders in that country’s Jirgatol and Khatlon regions planted Tajikston in the summer of 2015, whereas farmers in Tajikistan’s Ganci and Istravshan districts planted Fayzobod (CIP 397077.16).

Mdivani explained that farmers in Tajikistan’s lowlands successfully grew Tajikiston during the second summer growing season of 2015 – from August to November – when temperatures rise too high for the imported potato varieties. She noted that the heat-resistant, early-maturing varieties developed by CIP allow farmers to produce potatoes during a window between other crops, when land would otherwise lay fallow, which means more income for smallholders and better diets for people in rural communities.

CIP and partners have also evaluated the effects of different irrigation regimes – furrow irrigation, partial root-zone drying, and drip irrigation – on potato yield and production cost. Farmers at demonstration sites in Uzbekistan’s Ferghana and Andijan regions who applied recommended irrigation regimes doubled water productivity and reduced irrigation applications by 45%. Irrigation regimes and decision-support systems for improving water use efficiency were shared with hundreds of farmers, students, extension officers and researchers via field training, seminars, brochures, and a teleconference.

“We want to give farmers the opportunity for reliable yields and income generation without high dependence on diminishing natural resources such as water, or agrochemicals,” said Merideth Bonierbale, who leads CIP’s genetics, genomics, and crop improvement research.

She noted that while producing potato varieties and irrigation recommendations that will help Central Asian farmers increase their production in the short and long terms, the project also improved scientists’ understanding of the potato’s response to heat and water stress, and the presence of heat- and drought-tolerance within CIP’s potato breeding populations. This knowledge will inform efforts in potato breeding and crop management to help potato farmers in other regions facing similar challenges.

“All our learning is global. In fact, there are other regions of Asia that have conditions similar to the Aral Sea Basin’s, and heat and drought are affecting potato production in Africa and South America as well,” said Bonierbale. “As far as heat-tolerance goes, we think it will be the future of breeding, in light of climate change and the intensification of cropping systems needed to keep pace with food needs, especially in Asia. This project has thus been a good baptism of fire for CIP’s breeding program overall.”

New Network Improves Cooperation Around Late Blight Disease in Asia

CIP played an important role in the creation of AsiaBlight, an Asian network to improve collaboration and knowledge sharing on the management of potato late blight, a crop disease that has caused historic famines and remains a major constraint for smallholders around the world.

The first meeting of AsiaBlight was held in Beijing in July 2015 with approximately 50 participants from an array of countries, as a satellite event during the World Potato Congress. The proposal to create the network, however, had been approved in November 2014 at a CIP workshop in Nepal that brought together potato experts from ten Asian nations.

Though the pathogen behind late blight, Phytophthora infestans, is widely controlled with fungicides, those agrochemicals represent a significant cost and threat to the environment and human health. This is especially true for the smallholders in developing nations, who usually do not wear protective equipment, and whose diets and incomes CIP works to improve. Because they lack the necessary resources or knowledge, those farmers often fail to apply the fungicides properly, and suffer major crop loss despite using them.

“Late blight is a huge problem globally. It is managed with fungicides, but it’s still a big issue,” said Greg Forbes, a senior scientist at the CIP Center for Asia and the Pacific who was instrumental in AsiaBlight’s creation.

CIP has long bred late-blight-resistant potato varieties and promoted integrated approaches to managing the disease, but the pathogen’s propensity for spawning new lineages has complicated efforts to control it. A first order of business for AsiaBlight members is consequently to map the major genetic groups of Phytophthora infestans in Asia, as a baseline for studying the disease and designing better control strategies. A second major objective will be to develop collaborative arrangements between private and public partners to adjust disease management strategies to incorporate host plant resistance in the optimization of fungicide use.

Forbes explained that there are many advantages to regional cooperation, such as centralized data management, capacity building, and better selection of late-blight-resistant potato varieties. European scientists have been sharing knowledge on late blight since 1996 through the EuroBlight network, whereas their colleagues in the United States created USABlight in 2011. A Latin American late blight network called Red Tizón Latino – after the disease’s name in Spanish (tizón) – was launched in Bogotá, Colombia, in October 2014. The first Asiablight meeting included presentations on Red Tizón Latino and EuroBlight.

“CIP is kind of a broker in this, facilitating and trying to find funding for these different networks,” said Forbes. “As a global research center, we promote ideas such as standardization and better data management, and these networks can provide a mechanism for achieving them.”

Reaching Agents of Change to Spread the Benefits of Orange-Fleshed Sweetpotato Across Africa

The orange-fleshed sweetpotato (OFSP) is an important source of energy and beta-carotene, which is converted into vitamin A in the body and can prevent childhood blindness and diseases

Reaching Agents of Change to Spread the Benefits of Orange-Fleshed Sweetpotato Across Africa

The orange-fleshed sweetpotato (OFSP) is an important source of energy and beta-carotene, which is converted into vitamin A in the body and can prevent childhood blindness and diseases. One medium-size sweetpotato provides enough beta-carotene to meet the recommended daily allowance of vitamin A for children and non-lactating women. Because it matures quickly and can be farmed on marginal lands, OFSP has great potential for reducing hunger and vitamin A deficiency (VAD) in Sub-Saharan Africa (SSA). Yet there is inadequate awareness of that potential – or even the extent of the health threat posed by VAD – among government officials in the region.

To raise awareness of OFSP’s potential in SSA and generate new investments and policy changes to get OFSP into national, regional and sub-regional agendas, CIP teamed up with Helen Keller International (HKI) to implement the Reaching Agents of Change (RAC) project, in partnership with national research, education, and extension institutions. From 2011 to 2014, RAC advocated for increased investment in orange-fleshed sweetpotato (OFSP) to combat VAD among young children and women of reproductive age in targeted beneficiary countries. RAC also built institutional capacity to design and implement gender-sensitive projects to ensure wide access to and utilization of OFSP in Mozambique, Tanzania, and Nigeria, and to a lesser extent in Ghana and Burkina Faso. This work was funded by the Bill & Melinda Gates Foundation

RAC built the capacity of national advocates and regional champions to influence key decision makers to invest in promoting OFSP. At the same time, the project trained change agents on technical aspects of OFSP, who in turn conducted step-down courses to reach tertiary trainers and farmers. The following five-minute video highlights the key results achieved under RAC. A second short documentary called ‘The Wonder Root’ features RAC’s impact on the lives of beneficiaries and the extent to which the project achieved its intended outcomes.

SUSTAIN Rwanda Receives Visit from Ambassador Michael Ryan

SUSTAIN Rwanda Receives Visit from Ambassador Michael Ryan

Along the Kigali-Musanze highway in the Rulindo District of Rwanda lies a roadside market branded with the tell-tale orange of Orange-Fleshed Sweetpotato (OFSP). As one approaches, a sign reads “My Sweetpotato, My health, My wealth”, indicating bio-fortified OFSP ahead. Strategically placed to draw in motorists traveling down this main stretch of road, it is part of the Scaling up Sweetpotato through Agriculture and Nutrition (SUSTAIN) project’s goal of making OFSP a staple in the Rwandan diet.

On the last day of November 2015, Ambassador and Head of Delegation of the European Union Rwanda, Michael Ryan, stopped at the market as part of a learning tour to see how an agriculture-sensitive nutrition-for-health program is implemented on the ground. The OFSP market, the first of its kind in Rwanda, was designed to elevate the status of this particular tuber and differentiate it from the more common yet less nutritious white and yellow fleshed varieties, while creating a unique market for OFSP farmers to sell their harvests and cuttings. Its strategic placement along the highway not only makes OFSP easily accessible, but it also helps cement the OFSP brand in the minds of passing motorists. OFSP market vendors are well versed in the health benefits of their product and freely share their knowledge on preparation, storage, and the amount needed to counteract vitamin-A deficiency in young children. This is an essential message in a country where chronic malnutrition is as high as 40%.

Ambassador Ryan was able to chat with the farmers who sell at the market and tour the facilities. While a variety of OFSPs and other fruits and vegetables are displayed for sale on the red brick and concrete stalls, the Terimbere variety caught the ambassador’s eye. Weighing in at over 6 1/2 pounds, the hearty tubers are about the size of a newborn baby. International Potato Center (CIP for its acronym in Spanish) Rwanda Country Manager Kirimi Sindi accompanied the delegation. Much as CIP has been doing throughout Rwanda, he emphasized the OFSP brand, “Whenever I talk to a government official or a donor agency, we never talk about sweetpotato – we talk about OFSP, so that people ask what is different about this orange sweetpotato,” Sindi says. “It gives you an opportunity to communicate this message (about the importance of the orange flesh and its connection to nutrition).”

OFSP Opening Doors to Financial Health

It has been only five years since CIP first introduced OFSP as a way to counteract micronutrient deficiency in Rwanda, but the tuber is already having a big impact on the physical and financial health of the farmers who plant it. After a stopover at the market, the delegation then visited the KOTEMU group farm, one of the first farmer groups to start working with OFSP under the CIP project known as SASHA.

Because the group had worked with OFSP for at least four years, they were in a position to give the visitors insights into the production of vines and roots for marketing and processing. Farmers were able to address all questions posed by the visitors. In his interaction with farmers, the ambassador was eager to know how profitable sweetpotato farming was compared to other crops.

Margaret Muhayimana, a KOTEMU group member, has seen her life transformed since she began planting OFSP. Land holdings in Rwanda are small, a typical farmer only has just over a half an acre. Women in particular rarely earn a continuous income from farming. They grow the typical crops such as beans and maize. They save some of their harvest for household consumption and sell the rest on the open market. It is not enough to make ends meet, let alone pay for school fees, which often extends the cycle of poverty to the next generation. As a single mother and the only breadwinner for her family, Margaret faced additional financial hardships. Margaret explained that over the last five years, through the proceeds she has earned selling OFSP vines and roots, not only has she been able to pay school fees, but she has also been able to make substantive improvements to her family’s well-being, including: rebuilding her house, getting connected to the electrical grid, purchasing a dairy cow, paying for health insurance every year, and installing a biogas unit for producing gas for household use.

Margaret and her fellow farmers are able to achieve such successes because OFSP can be grown throughout the year. Despite the fact that the ambassador visited right at the start of the rainy season, a time when any other crop would just have been planted, he was able to see sweetpotatoes ready for harvest. “You can plant it (OFSP) at the beginning of the season, the middle of the season, or the end of the season,” says Sindi. “The beauty of it is that it needs very little input. You can grow it with almost no fertilizer and it is not sensitive to rain patterns.”

Since OFSP grows from vines that need to be planted at the most three days after cutting, farmers like Margaret have a steady income selling vines to other interested farmers. From December 2014 to June 2015 alone, the SUSTAIN project produced and distributed 4 million OFSP cuttings to 20,000 eligible households in eight districts, opening the door to financial and nutritional health to a whole new crop of poor farming families.

Creating OFSP Products for Sale on the Local Market

In order to make OFSP ubiquitous in the Rwandan diet, creating demand is essential so that farmers have a steady market for their product. To do this, CIP has developed the technology of substituting OFSP puree for up to 50% of the wheat flour contained in baked goods. This raises the nutrient content of the baked goods and lowers the production costs. SUSTAIN has linked farmers to major manufacturers such as Urwibutso Enterprises that uses OFSP in its Golden Power Biscuits and other bakery products that yielded US $364,410 in sales in one year alone. To reach more farmers, however, it is essential to create local market opportunities that farmers can tap to sell their products. Cooperatives that can produce their own puree to be used in goods sold on the local market are able to keep more of the earnings in their own coffers.

The climax of the field visit was a tour of a farmer cooperative run processing unit located in the Gakenke district of Rwanda. Members of the cooperative explained the process of transforming fresh OFSP roots into value-added products for sale, such as mandazi (a type of doughnut) and queen cake to the Ambassador. Various bakery products were showcased and tasted by members of the delegation. The team was impressed at the great variety of products that can be made using OFSP as an ingredient.

At the end of the visit the Ambassador expressed his gratitude for an educational, enlightening, and comprehensive field trip and said he was looking forward to other opportunities of seeing more work in the near future as CIP expands it program in Rwanda.

SUSTAIN is a five-year partnership (2013-2018) coordinated by CIP and financed by the UK Department for International Development, to scale up the nutrition benefits of biofortified orange-fleshed sweetpotato (OFSP). The goal is to reach 1.2 million households with under-five-year-old children in Kenya, Malawi, Mozambique, and Rwanda.

Linking Orange-Fleshed Sweetpotato with Healthcare in Kenya Benefits Women and Children

Thousands of pregnant women, mothers, and young children in Western Kenya are healthier thanks to an innovative, CIP-led initiative that links agriculture, health provision and nutrition education to get mothers to grow, eat, and feed their children nutritious orange-fleshed sweetpotatoes: a vital source of vitamin A.

Vitamin A-deficiency (VAD) is a major health problem in Africa and Asia, where it primarily affects young children and pregnant or lactating women. According to the World Health Organization, VAD is the leading cause of preventable blindness in children, with an estimated 250,000 to 500,000 vitamin A-deficient children going blind each year, half of whom die within a year of losing their sight. VAD also causes night blindness in pregnant women and increases the risk of maternal mortality.

In response to this scourge, CIP promotes the cultivation and consumption of orange-fleshed sweetpotato (OFSP): an important source of beta-carotene, which is converted to vitamin A in the body. One medium-size OFSP provides enough beta-carotene to meet the recommended daily allowance of vitamin A for a child or non-lactating woman. OFSP is a CIP priority in Sub-Saharan Africa (SSA), where CIP scientists help local institutions develop more resilient, bio-fortified OFSP varieties, and work with partners to distribute clean OFSP planting material, promote good agricultural practices, strengthen value chains, and educate people about the crop’s health benefits.

A major focus is to reach pregnant women and young children, since eating OFSP and other vitamin-rich foods during the first 1000 days of life is crucial to preventing blindness and other malnutrition-linked ailments. While CIP has traditionally worked with institutions dedicated to agriculture, the quest to achieve OFSP’s full potential for improving health has involved a wider range of partners and approaches.

As part of CIP’s research on nutrition interventions and scaling methods, one innovative strategy has been to integrate agricultural extension with nutrition education and healthcare provision. CIP and partners are using this approach within the framework of Scaling up Sweetpotato Through Agriculture and Nutrition (SUSTAIN), a five-year initiative (2013-2018) coordinated by CIP and financed by the UK Department for International Development, which targets households with children under five in Kenya, Malawi, Mozambique, and Rwanda. In Kenya’s Nyanza Province, women who visit rural health centers for antenatal care are now given nutrition education and vouchers for planting material of improved OFSP varieties, as part of an effort to get them to grow OFSP, eat it, and feed it to their children.

The approach was developed under a previous intervention in Kenya called MamaSASHA, a component of CIP’s Sweetpotato Action for Security and Health in Africa (SASHA) project that ran from 2010 through 2014, for which CIP partnered with the international health nonprofit PATH. While nurses at antenatal care centers taught patients about OFSP and distributed vouchers for planting material, community health workers followed up through pregnant women’s clubs. Agricultural extension agents distributed OFSP vines for planting and taught women how to grow the crop and multiply vines for sale to other farmers. The project also included events where women learned how to prepare a variety of OFSP dishes.

The effectiveness of this approach in improving nutrition and health was confirmed by a longitudinal cohort study undertaken with 505 women from mid-pregnancy through nine months postpartum. By the end of that study, dietary vitamin A intake among both mothers and infants in the MamaSASHA intervention area was nearly twice that of controls. VAD among mothers had also decreased compared to those in control areas.

VAD remains a major public health problem in Kenya, affecting more than 80% of pre-school aged children and 17% of pregnant women, which is why CIP has continued this approach under SUSTAIN. In Nyanza Province, CIP is cooperating with PATH and Kenya’s Ministry of Agriculture and Ministry of Public Health. Though SUSTAIN is only in its third year, health providers at participating facilities have reported that more pregnant women are seeking ante-natal care early and more children are completing post-natal care, which is in part due to SUSTAIN’s nutrition education efforts. Project personnel have counseled mothers on feeding infants and young children, showed them how to make OFSP baby food, and shared recipes that integrate OFSP into popular local dishes.

The effectiveness of this approach for improving infant health is reflected in the words of one of the beneficiaries, who said: “From the mother support club meetings, I have gained confidence to exclusively breastfeed my child, and at six months, to introduce him to OFSP baby food. He does not fall ill often like my other children.”

CIP and RTB:
a winning alliance for achieving the SDGs

CIP and RTB: a winning alliance for achieving the SDGs

CIP is both the lead center for the CGIAR Research Program on Roots, Tubers and Bananas (RTB) and part of the broader RTB alliance with diverse and complementary partners. CIP has played a key role in making RTB into one of the most successful of CRPs, and reciprocally CIP benefits from the broader perspective which RTB brings. For example, CIP’s outstanding progress in promoting orange fleshed sweetpotato is inspirational in developing more general approaches in RTB to enhancing the use of nutrient dense foods. And vice versa, CIP has benefited from RTB’s approaches to results based management in working with stakeholders to co-develop impact pathways. So together CIP and RTB make a winning alliance for achieving the SDGs.

Last year RTB and CIP moved ahead strongly in research and outcome delivery, as reflected in the 2015 Independent Evaluation Arrangement (IEA) review, which noted that “in spite of the complexities and challenges of successfully implementing a multi-crop and multi-partner CRP, RTB has made notable progress in the past four years and is already delivering results, in spite of budget cuts. RTB is well-directed and reaching a reasonable number of its near-term milestones and is working towards achieving its goals, particularly those concerning productivity and nutritional improvement” (http://bit.ly/24xsQcq).

Among the successes CIP achieved with RTB in 2015 was the development of pest risk assessment documents for staple crops including sweetpotato and potato to help governments, non-governmental organizations and the private sector in SSA better assess, prepare for, and confront the risk of crop pests and diseases under climate change. Through the project, CIP scientists adapted their Insect Life Cycle Modeling software, developed for potato pests, to understand how rising temperatures affect the pests in all RTB crops and what new technologies are needed to deal with this. RTB has also made notable strides in incorporating gender, including the development of a gender responsive framework for participatory varietal selection where gender researchers at CIP contributed significantly.

In 2015 RTB finalized the move to a new program structure, based on flagship projects (FPs) and clusters of activity (cluster), starting from January 2016 (http://bit.ly/1qGmOqk). CIP’s strategic objectives are highly aligned with the FPs and CIP scientists are leading the research areas for productive varieties and quality seed and for nutritious food and value added. FPs and cluster business cases were laid out by the RTB scientist teams, including partners, and were subjected to an intensive external review process in May/June 2015. Detailed feedback from this review, the IEA evaluation, and donors, as well as broad discussions among the RTB teams, informed the cluster design and their integration into FPs and the new program structure. RTB’s targets, known as IDOs, are fully aligned with the Sustainable Development Goals (SDGs) (Table 1). This sets the scene for the submission of the Preproposal for RTB Phase II, which was highly rated by the Independent Science and Partnership Council.

SDGs	IDOs	RTB Targets (2022)
	Increased incomes and employment	20,000,000 people (50% women) increased their income 30,000 small and medium enterprises operating profitably in the RTB seed and processing sectors
	Increased productivity	8,000,000 farm households increased RTB crop yield through the adoption of improved varieties and sustainable management practices
	Improved diets for poor and vulnerable people	10,000,000 people (50% women) have improved their diet quality
	Enhanced benefits from ecosystem goods and services	1,900,000 ha of current RTB crops production area converted to sustainable cropping systems
	More sustainably managed agro-ecosystem
	Mitigation and adaptation achieved	Capacity to deal with climate risks and extremes increased for at least 2,000,000 HH
	Equity and inclusion achieved	At least 35% increase in # of female and young beneficiaries of at least 700,000 HH perceived to have better control over assets and resources
	Enabling environment improved	Individual capacities improved for at least 9,500 individuals (50% women) in research for development partner organizations Capacity for innovation increased in at least 60 development-focused organizations, including women's networks and alliances At least 5 partnership and scaling models tested in a minimum of 5 target countries and adjusted to be fit for purpose
	National partners and beneficiaries enabled	Regulatory frameworks, policies, and national programs in relevant areas under implementation in at least 20 country per policy change
