Food Security under Water Scarcity: a comparative analysis of Egypt and Jordan
This paper analyses how the application of the global trade and self-sufficiency food security strategies under water scarcity have evolved in Egypt and Jordan before, during and after the 2008 world food price crisis.
An operational framework was developed to predict field crop biomass using high resolution multi-source satellite data. Five regression algorithms were tested to assess their suitability to predict field scale sugarcane biomass production in the Wonji-Shoa estate, Ethiopia. The results showed that linear regression models outperformed non-linear machine learning models with 89% accuracy achieved 4 months before harvest.
Translating open-source remote sensing data to crop water productivity improvement actions
This study presents a framework to translate RS based WP data to actionable information. Six factors (crop water stress, irrigation uniformity, soil salinity, nitrogen application, crop rotation and soil type) derived from RS were analysed to identify their influence on WP and yield. Such information with regard to WP factors assists practitioners to identify priority areas and actions aiming at crop field level WP improvement.
This study presents a framework that applies WaPOR data to assess irrigation performance indicators including uniformity, equity, adequacy and land and water productivity differentiated by irrigation method (furrow, sprinkler and centre pivot) at the Xinavane sugarcane estate, Mozambique.

Project reports and case studies
Trends in water consumption, production and water productivity in IsDB member countries
This report provides an overview of changes in agricultural indicators from 2009 to 2020 in a selection of Islamic Development Bank member countries. The data can also be viewed interactively in Google Earth Engine. The data includes the following agricultural indicators: actual evapotranspiration and interception (AETI), total biomass production, gross biomass water productivity, reference evapotranspiration (RefET), precipitation (P), AETI/RefET and AETI/P over irrigated or rainfed areas.
Compendium of approaches to improve Water Productivity
This compendium focusses mainly on interventions that improve the biophysical water productivity. While the focus is on improving water productivity, it also includes interventions that improve land productivity and the water use efficiency as they go hand in hand. The interactive website can be found here.
Case studies
The objective of this case study was to provide insight on how to improve agricultural water management to increase agricultural yield while maintaining factory production in the Xinavane sugarcane estate. This was done by analysing the spatiotemporal variability in water productivity, land productivity, and other irrigation performance indicators for different irrigation methods. In addition, the impacts of increasing water productivity to a target value ("closing the productivity gap") is assessed. Learn more about this case study in our 2-pager.
The objective of this case study is threefold: first, to shed light onto the agronomic factors that affect yield production and water productivity using AquaCrop simulations; second, to facilitate a comparison between the results of AquaCrop and those of WaPOR; and third, to investigate possible causes of discrepancies between WaPOR and AquaCrop results. This was done by conducting AquaCrop simulations and WaPOR analyses on 5 farms in Kenya and comparing the results. Water productivity related indicators (including yield, biomass production, and water consumption, among others) were obtained.
The main objective of this study was to provide insight into water and land productivity, and irrigation performance at the Wonji-Show Sugar Plantation using WaPOR derived data. This was done by analysing the spatial variation among irrigation application methods. Furthermore, the productivity gaps and implications of closing these gaps for production and water use are explored, considering water allocation in Awash River Basin.

Policy reports and briefs
Following a review of the agricultural policies on water and agriculture a stakeholder dialogue was implemented in November 2022 in Kenya. The review explored the concept of water productivity in its broader sense for Kenya. Report & Brief
The role of the water productivity concept in water and agricultural policies was evaluated for Egypt. The review evaluated vertical expansion against horizontal expansion in the Nile Delta. Report & Brief
For Jordan, the policy review aimed to shed light into the national plans for agricultural water management in relation to water productivity. The review further focussed on comparing the irrigated highlands with the Jordan Valley. Report & Brief
The policy review for Sudan discusses the aspects of the Acts and Policies that contributed to the current poor status of the agricultural sector, followed by the future outlook. Report
Framework for policy assessment
The framework starts with how to conduct a policy review on agricultural water productivity and assess its implications for national development objectives. The goal is to link the policy review results to biophysical impacts using WaPOR data to examine past increases or decreases in evapotranspiration (a measure for water use) or biomass (a measure for agricultural production). This is followed by Policy Dialogues aimed to help improve water productivity. The Integrated Assessment Framework can be applied to score different agricultural development strategies against various technical, economic and social indicators, with the ultimate goal of providing a holistic understanding of development strategies and their (inherent) trade-offs.
Standardized protocol for diagnostic analysis for water productivity variations
This protocol focuses on analyses that can be conducted to explain the reasons behind spatial and temporal biophysical water productivity (BWP) variations. The first aim of this protocol is to delineate the agronomic principles that affect water productivity (section 2). Second, this protocol aims to show how to make use of various existing tools that can provide diagnostic insights (section 3). The report can be found here, as well as the supporting excel files for field surveys and data collection for Aquacrop.
