Water productivity

"Water productivity refers to what we can produce from a unit of input, it is also a ratio of output to input but both do not need to have the same units, e.g. WP is 50kg grains per 1 m3 of water" (Ragab 2014)

FAO CB4WA: Use of FAO WaPOR Portal

Overview

Welcome to the open access course Use of FAO WaPOR Portal from IHE Delft Institute for Water Education and the Food and Agricultural Organization of the United Nations (FAO). WaPOR is the portal to monitor Water Productivity through Open-access of Remotely sensed derived data and has been developed by FAO. The FAO’s WaPOR programme assists countries in monitoring water productivity, identifying water productivity gaps, proposing solutions to reduce these gaps, and contributing to a sustainable increase in agricultural production.

Water accounting is the process of communicating water resources related information and the services generated from consumptive use in a geographical domain, such as a river basin, a country or a land use class; to users such as policy makers, water authorities, managers, etc.

The training platform includes links to freely available online training and exercises on water accounting, as well as a webinar series by ADB, IHE Delft, and recordings of relevant presentations in various languages.

Water problems around the world are increasing; however, information useful for decision makers within the water sector and related to the water sector seems to be decreasing. Solving water problems requires information from many disciplines, and the physical accounts (describing sources and uses of water) are the most important foundation. The information has to be coherent and harmonized in order to provide an integrated picture useful for the assessment of the problems.
