This document describes the methodology used to produce data
through the portal on Water Productivity through Open Access of
Remotely sensed derived data (WaPOR). It specifically concerns data
at 250m (Level 1), 100m (Level 2) and 30m (Level 3) resolution
distributed through WaPOR Version 2, which was launched in June
2019 based on extensive internal and external validation and
quality assessment. The portal provides open access to various
spatial data layers related to land and water use for agricultural
production and allows for direct data queries, time series
analyses, area statistics and download of key variables to estimate
water and land productivity gaps in irrigated and rainfed
agriculture. As of today, it provides access to 11 years of
continued observations over Africa and the Near East.Achieving food
security while using water resources in a sustainable manner
represents a major challenge for current and future generations. An
increasing population, economic growth and climate change all add
to the pressure on available resources, including intensive water
use for agriculture. Systematic monitoring of water productivity
through the use of remote sensing techniques can help to identify
gaps and evaluate appropriate solutions.
