Water Productivity Improvement in Practice

Work Package 1: Assisting water projects

The objective of Work Package 1 (WP1) is to guide water projects and programs in understanding the concept of water productivity, to be able to report on trends in water productivity, identify causes for variability and decline in water productivity, and to be able to select a course of action for improving water productivity. All of these efforts will work towards the target of increasing water productivity by 25% as stipulated by the Dutch governmental agenda. The definition of water productivity used here is broad, and includes biophysical and socioeconomic parameters.

The aim is to develop standardized protocols for analyzing biophysical water productivity (e.g., using WaPOR or AquaCrop), to complete diagnostic analyses to identify the causes for low water productivity, and to identify and discuss measures to improve water productivity with (agricultural) water managers and users. These will be tested and implemented in selected case studies. For case studies where clear recommendations can be provided, the project team will work with the project leads and system managers to work towards implementing these recommendations.

Standardized Protocol for Land and Water Productivity Analyses using WaPOR

This standardized protocol provides Python scripts which can be used to calculate land and water productivity and other performance indicators such as uniformity, efficiency (beneficial fraction), adequacy, relative water deficit as well as estimating productivity gaps. Go to the Github repository to view and download the Jupyter Notebooks with the protocol.

Case Study: Xinavane, Mozambique

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.

Case Study: Cropmon, Kenya

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.

Case Study: Wonji, Ethiopia

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.
