The present issue of Hydrolink includes articles from three countries with a long history of facing droughts and learning over the years how to manage them. Drought is defined broadly as the condition of “a moisture deficit relative to the average water availability at a given location and season”. Droughts are often categorized as meteorological (prolonged periods of below average precipitation), hydrological (prolonged periods of lower than average streamflows of groundwater availability) and agricultural and ecological droughts (periods of soil moisture deficit during the growing season affecting negatively crop production or ecosystem functions). These three types of droughts are closely related as meteorological droughts causes hydrological droughts, and they both, in combination with high evapotranspiration, contribute to agricultural and ecological droughts.
