Explanation:

FAO’s Global Information and Early Warning System (GIEWS) was established in 1975 in the wake of the world food crisis of the early 1970s.
The System has the mandate to continuously monitor the global food supply and demand situation and alert the international community of countries or regions threatened by serious food shortages or which have exceptional localised or exportable surpluses of food available for donor purchases and distribution to deficit areas.
One of the System’s exceptional assets lies in the vast database at its disposal on global, regional, national and sub-national food security which is continuously updated and refined.
Through its monitoring, analysis and early warning activities, GIEWS provides a significant contribution mainly to three of the Organization’s Strategic Objectives (SOs):
SO1: Implementation of the GIEWS Food Price Monitoring and Analysis (FPMA) Tool at country level enhances accessibility of price data and strengthens national capacities to monitor price trends contributing to improved policy decisions for food security.
SO4: Commodity supply/demand and price databases, as well as related indices and analysis, are kept up to date, providing governments and national stakeholders timely, accurate information on which to base the design of efficient and inclusive market and trade strategies.
SO5: Regular assessments at country level of agriculture, food supply and demand, and market situation, permits timely alerts on production and food security shocks. In addition, GIEWS provides support to national institutions, including training on food security analysis
and implementation of monitoring tools, to strengthen national early warning systems.
