PEDA An advocacy tool modelling
the interrelationships between population, the environment, development
and agriculture PEDA is an interactive computer simulation model (developed for MS-Windows environment), demonstrating the medium to long-term impacts of alternative national policies on the food security status of the population. The model is based on multi-state demographic techniques, projecting at the same time eight different sub-groups in the population of a country broken down on the basis of three dichotomous characteristics, i.e., urban/rural place of residence, literacy status and food security status. Through the manipulation of scenario variables, the model enables the user to project the proportion of the population that will be food secure and food insecure for a chosen point in time throughout the projection period. As food security is a factor of developments in the fields of population, agriculture, the environment and socio-economic development, the model demonstrates the relationships between these fields as well. The PEDA model was developed by the United Nations Economic Commission for Africa with the assistance of Drs. W. Lutz and S. Scherbov of the International Institute for Applied Systems Analysis (IIASA).
