In the Policy Dialogue Model the Cereal Production is the national food production under
both irrigated and rain-fed conditions by her population. The main driving forces behind
agricultural production include developments in total harvested area, expansion of the
irrigated area and increasing crop yields under rain-fed and irrigated conditions. Details
concerning variables and data sources are given in the figure below
Use this Documentation Link for more specific information about Scenarios and Drivers in the Policy
Dialogue Model. This documentation also provides the equation which is used to get the numbers,
like used in the PODIUM. Projections of total food production—the sum of rain-fed and irrigated
production—are compared to the required amount of food as determined in the first computation step.
Countries facing a deficit are regarded as food importing countries while countries with surplus
production are food exporters.
