 Climate change are undeniable, droughts are increasing, heavy rainfall and unpredictable weather events are now the norm. As a consequence, small-scale farmers often lose their crops and now must work harder than ever to produce enough food in a sustainable manner to survive. The Sustainable Development Goals call for zero hunger and efficiency of water use in all sectors. To help meet the challenge, FAO has developed Vapor, a remote-sensing database which allows for the monitoring of agricultural water productivity. Vapor gives users access to a wide variety of real-time satellite data on water productivity collected over a span of 10 years. This information can be used to propose solutions to increase water productivity while respecting the environment and making equitable use of water resources. Governments and research institutes are already using Vapor to design strategies based on factual data. And in the field, mobile apps developed by FAO and third parties use Vapor data to provide farmers with information on local conditions of water and vegetation. These apps also use artificial intelligence to detect plant pests and diseases. Farmers can make the right decisions. They can decide to increase soil fertility and reduce water use and ensure that the correct crop is grown in appropriate climatic conditions. This tool helps manage every drop for every crop, both now and in the future. Vapor is expanding to new areas and new applications. Join us to build a water and food secure future where no one is left behind.
