WaPOR, remote sensing for water productivity

Water accounting

Transparent and comprehensive information of water resources is needed for sustainable integrated water resources management. Water accounting is the systematic analysis of the current status and trends in water supply, demand, distribution, accessibility and use in time and space within specified domains, producing a basis for evidence-based water policy decision-making (FAO, 2017). Water accounting outputs reveals how water is used across different sectors and help shape an understanding of the benefits and existing trade-offs of the water allocations and use patterns. The integrated and cross sectoral presentation of the information in water accounting helps the users to see the bigger picture and cross linkages in water management.

Understanding the current status of water resources systems globally requires detailed information on the source of water in space and time as well as detailed information on the utilisation of those water resources. Unavailability of sufficient observed data is a big issue in most parts of the world to be able to fully assess available water resources and its utilisation. Fortunately, more and more remote sensing based products are becoming available, providing information on various components of the water cycle, such as precipitation, actual evapotranspiration and storage variations.

This report describes the rapid water accounting study for the Jordan River Basin using the Water Productivity (WaPOR) database. The water accounting has been carried out in collaboration with IHE Delft using the FAO Water Productivity (WaPOR) data portal, to gain full insights into the state of the water resources in the basin for the period from 2009 to 2018.

The Nile River Basin faces a huge challenge in terms of water security. With an expected doubling of the population in the basin in the next twenty-five years, water supply in the basin will be further depleted as demands for agriculture, domestic and industry continues to grow. This report describes the water accounting study for the Nile River Basin carried out by IHE-Delft using the Water Productivity (WaPOR) data portal of the Food and Agricultural Organization (FAO).

WaPOR Version 2 was launched in June 2019 based on extensive internal and external validation and quality assessment. This report describes the methodology used to produce the different data components of WaPOR Version 2 at the 250m (Level 1), 100m (Level 2) and 30m (Level 3) resolution, as made available through WaPOR version 2.0 release.

WaPOR Version 2 was launched in June 2019 based on extensive internal and external validation and quality assessment. This report, developed in collaboration with ITC-Twente and the other partner of the FRAME Consortium, provides a quality evaluation of the WaPOR V2 evapotranspiration, biomass and water productivity data across Africa and the Near East, currently distributed through the FAO's WaPOR portal.

This technical report focuses on Koga, in Ethiopia, and describes the process of developing, designing, piloting and evaluating potential solutions to increase water productivity sustainably, which is the third objective of component 4 of the WaPOR project. It uses WaPOR data to measure the changes occurring after the implementation of low-cost tools and irrigation practices so as to: increase yield and to reduce the water consumed or applied during the irrigation season.
