Synopsis (short abstract) Guidelines to GIEWS’ Earth Observation website in order to help the viewers with navigation through the website. The Earth Observaiton for Crop Monitoring Tool supports its analysis and supplement ground-based information. The Global Information and Early Warning System on Food and Agriculture (GIEWS) utilizes remote sensing data that can provide a valuable insight on water availability and vegetation health during the cropping seasons. In addition to the rainfall estimates and the Normalized Difference Vegetation Index (NDVI), GIEWS and FAO’s CBC Division have developed the Agricultural Stress Index (ASI). Every ten days, the System generates a map showing the hot spots around the world, where crops are affected by water stress during the growing period and the information is verified with field observations to corroborate the remote sensing analysis.

    Established after the food crises of the early 1970s, the Global Information and Early Warning System on Food and Agriculture (GIEWS) continuously monitors and reports on food supply and demand across the world. It is a leading source of information on food production and food security at national, regional and global levels. Through assessments and reports, GIEWS alerts national and international decision makers on impending food crises, aiming to guide their intervention. GIEWS provides comprehensive market intelligence on agricultural commodities and supports national and regional initiatives to establish and enhance early warning systems.

    Observation of bioindicators as early warning systems to mitigate the impacts of frosts and droughts in Bolivia 2011
    Also available in:
    Weather in the Andean high plateau is characterized by extreme climate events with serious impacts for agriculture, increasing the vulnerability of farmers. The lack of forecast weather stations in the region leads to lack of data and thus weakens timely decision-making. Implementation of modern agro meteorological services would imply high costs. However, local communities in the Omasuyo province in Bolivia traditionally rely on the observation of local bioindicators which provide a kind of local agro meteorological service that has produced reliable guidance over centuries for mitigating the impacts of extreme climate events on crops.
