Monitoring and Predicting Agricultural Drought: A Global Study


Accurate monitoring and prediction of agricultural droughts helps manage them, minimize losses attributed to them, and mitigate their extreme forms, which some countries face even today. This book presents the basic concepts of agricultural drought, various remote sensing techniques used to monitor them, and efforts by international organizations to check them.

Of the many climatic events that influence the Earth's environment, drought is perhaps the one that is most linked with desertification. Drought is the consequence of a natural reduction in the amount of precipitation received over an extended period, usually a season or more in length.

Drought disrupts cropping programmes, reduces breeding stock, and threatens permanent erosion of the capital and resource base of farming enterprises. Continuous droughts stretching over several years in different parts of the world in the past significantly affected productivity and national economies. in addition, the risk of serious environmental damage, particularly through vegetation loss and soil erosion, as has happened in the Sahel during the late 1960s and early 1970s, has long-term implications for the sustainability of agriculture. Bush fires and dust storms often increase during the dry period.

As the United Nations' specialized agency with responsibility for meteorology, operational hydrology, and related geophysical sciences, the World Meteorological Organization (WMO), since its inception, has been addressing the issue of agricultural droughts. the fight against drought receives a high priority in the wmo Long-Term Plan, particularly under the Agricultural Meteorology Programme, the Hydrology and Water Resources Programme, and the Technical Co-operation Programme. wmo involves actively the National Meteorological and Hydrological Services (NMHSs), regional and sub-regional meteorological centres, and other bodies in the improvement of hydrological and meteorological networks for systematic observation, exchange, and analysis of data for better monitoring of droughts and use of medium- and long-range weather forecasts, and assists in the transfer of knowledge and technology.

In order to provide leadership in addressing related issues, wmo has been in the forefront of research on interactions of climate, drought, and . . .
