The Food and Agriculture Organization (FAO) will develop an open-access database using satellite information to support water-scarce countries in the Near East and North Africa, where droughts and food security are major issues. The portal’s objective is to gather and assess satellite data in order to enhance land and water productivity, and to foster the sustainability of agricultural systems.

There is a need for wider coordination between conservation organizations and space agencies to decide which variables tracked from space can be useful in order to monitor changes in biodiversity on a global scale. It is crucial to identify these changes as they may very well have impacts on the occurrence of natural disasters, such as droughts, landslides, floods and wildfires.
