Descripción
In Sri Lanka, the project Knowing water better - Towards a more equitable and sustainable access to natural resources to achieve food security (KnoWat) established a modern geospatial database based on the FAO’s Water Productivity through Open-access of Remotely sensed derived data (WaPOR) tool. Different data on water resources are needed to assess and improve water management. In Sri Lanka, the lack of reliable data on water resources made for example agricultural predictions, plans and decisions challenging.
