  • Inaugural African Drought Atlas Training Course Held

    Saturday, November 17, 2018
    In October 2018, after over a decade of effort, a Drought Atlas for Latin America and Caribbean was released by UNESCO-IHP and the Water Center for Arid and Semi-Arid Zones in Latin America and the Caribbean (CAZALAC). The Atlas uses Regional Frequency Analysis (RFA), based on a statistical method called L-moments, to assist drought planners and decision-makers in both public and private sectors.  During an African regional workshop on “Climate Change Risk, Vulnerability Assessment and Early Warning for Africa”, held on 13-16 June 2017 at the AGRHYMET Centre in Niamey, Niger, the need had been...

    Saturday, September 29, 2018
    One of the techniques for drylands water management identified in the earliest years of the G-WADI network was for the collection and management of flood- or rainwaters to increase water availability for domestic, agricultural or ecosystem use. This approach, called “water harvesting”, has been a traditional means of storing water in the Indian Subcontinent, the Middle East, North and East Africa, and the Americas for millennia. G-WADI Workshops on the topic have been held on three continents, beginning in 2005. Most recently, the Regional Centre for Capacity Development and Research in Wate... Read More
