The effects of climate change, population growth and economic development in the Mediterranean are posing a threat to the water supply in the region. As part of ESA’s TIGER initiative, satellite data are supporting water management by identifying water resources. The demand for water is growing around the Mediterranean and is especially crucial in areas that do not receive regular rainfall. This is especially true for the southernmost parts of Europe and the countries lying along the African coast and in the eastern Mediterranean Basin.
Owing to the increasing population, the demand for water is growing for drinking and irrigation, representing 70–80% of the water use in the region. To get a better grip on water management, satellites are increasingly acknowledged as indispensable tools for collecting information on available water resources and their use. This information is also necessary for planning infrastructure, such as where to build a dam, how to divert a waterway or manage a flood event.
The ten-year TIGER initiative exploits Earth observation technologies in order to respond to the urgent need for reliable water information in Africa. TIGER is currently collaborating with the Euro-Mediterranean Information System on Know-How in the Water Sector (EMWIS), organising water observation systems and building capacity in the Mediterranean region.
