Synopsis (short abstract) 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.

    The project Knowing water better - Towards a more equitable and sustainable access to natural resources to achieve food security (KnoWat) carried out a water tenure assessment in the Malwathu Oya southern catchment. The assessment identifies and compares the various water tenure arrangements that exist in Sri Lanka and highlights the challenges that may hinder the effectiveness of those arrangements. It also provides recommendations on how to achieve a more responsible and equitable governance of water tenure.

    The project Knowing water better - Towards a more equitable and sustainable access to natural resources to achieve food security (KnoWat) carried out a water accounting and auditing assessment in Sri Lanka. Water accounting and auditing are an essential aspect of managing water resources: water accounting is the systematic examination of status and trends in the availability, demand, accessibility and usage of water, and water auditing puts trends in water supply, demand, accessibility, and usage into a broader framework of governance, institutions, public and private expenditure, law and the political economy of water. When combined, water accounting and auditing facilitate policy development and decision-making.

    The project “Knowing water better: towards fairer and more sustainable access to natural resources” (KnoWat) has built stronger water governance processes in Rwanda, Senegal and Sri Lanka. The project has strengthened national capacities in water accounting and water productivity in agriculture, using the latest remote sensing technologies and training hundreds of water experts. KnoWat has also developed and tested a methodology for assessing water tenure to shed light on the rules and regulations governing access and allocation of water resources. This short publication summarizes the key accomplishments of the KnoWat project in Sri Lanka.
