Dt  Doubling time; the time it would take a population to double, given there are no changes in age-specific mortality or fertility rates

PRA Pest Risk Analysis
rm   Intrinsic rate of increase; a measure of the rate of growth of a population. This assumes the population is in stable age distribution. It is equal to the natural log (In) of the finite rate of increase
Ro   Net reproduction rate; the average number of offspring an individual female will produce in her lifetime. Unlike the GRR, Ro depends on age-specific mortality rates
.RTB   CGIAR Research Program on Roots, Tubers and Bananas
SSA   Sub-Saharan Africa
T  Generation time; the average age at which a female gives birth to her offspring. This is equivalent to the time it takes for a population to increase by a factor equal to the net reproductive rate.
