Book (series)The Global Agriculture Perspectives System (GAPS) 2016

No results found.The purpose of this document is to provide a full description of FAO’s partial equilibrium modelling system known as GAPS. GAPS has been developed by FAO to study the development of global food markets in the long-term and to assess how socioeconomic fluctuations, climate change and investment pay-offs may affect future global food demand. At its core GAPS is a standard recursive dynamic multi-market and multi-regional partial equilibrium model, complemented by a module enabling to report undern ourishment indicators. GAPS is a simple self-contained model which specifies demand and supply for agricultural and food commodities with global coverage and great detail for low and middle income countries. It is shaped around FAOSTAT data on production and commodity balance sheets, which enables a detailed specification of agricultural and food commodities. Furthermore, GAPS allows to assess impacts of changing conditions in food commodity markets on the prevalence of undernourishment. This ma kes GAPS a suitable tool to simulate future food supply requirements in the context of changing demand and ambition to eradicate hunger and malnutrition. -
Poster, bannerThe future of food and agriculture (FOFA): Quantitative modelling framework 2018
Also available in:
No results found.To provide projections of relevant food and agriculture variables in foresight exercises, the FAO Global perspectives Studies team uses two main quantitative economic models: the FAO Global Agriculture Perspectives System (GAPS) and the Environmental Impact and Sustainability Applied General Equilibrium (ENVISAGE) model. FAO GAPS is a partial equilibrium model that focuses on the relationships between production and consumption of food and agriculture goods, and food security and nutrition. The ENVISAGE model covers the whole economy and portrays the frame for the food and agriculture sectors. Both models allow scenarios to be internally consistent, as they ensure: i) respect of certain physical and economic balances, such as the matching of demand and supply for goods and services under scenario-specific assumptions on population growth, technological progress, and natural resource constraints under changing climate conditions; ii) compliance with selected theoretical restrictions, such as limits on food expenditure imposed by available income and matching value added generation and outlays.
