Book (series)Guidelines for calculation of the agriculture water use efficiency for global reporting
The agronomic parameters in the SDG indicator 6.4.1: yield ratio and proportion of rainfed production
2022These guidelines are intended to assist countries in understanding the agronomic parameters involved in the computation of the agricultural component of the Sustainable Development Goal (SDG) indicator 6.4.1 on the change in water use efficiency over time. They provide a detailed explanation of the calculation process for calculation by countries willing to generate a more accurate estimation using their national data. The guidelines provide the minimum standard method using an estimated or default value proposed by FAO, as well as the available methodologies to progressively improve the accuracy through a monitoring ladder for countries that have more comprehensive and accurate data on their main crops areas and productions. -
Book (series)Change in water-use efficiency over time (SDG indicator 6.4.1)
Analysis and interpretation of preliminary results in key regions and countries
2019Also available in:
No results found.The purpose of this document is to provide suggestions for the interpretation of the Sustainable Development Goals (SDG) indicator 6.4.1. In particular, it focuses on the concept of economic decoupling from water-use, and its application in policy making. The evolution in water-use and water-use efficiency in four selected regions: Europe, Latin America and the Caribbean, Southeast Asia and Sub-Saharan Africa, is discussed. Particular attention is given to the evolution in water-use, water-use efficiency and related drivers in two groups of countries, including major developed economies and newly industrialized countries, and in different economic sectors. The relation of water-use efficiency with economic growth and access to safe drinking water is analyzed and discussed in the context of the literature on the Environmental Kuznets Curve applied to water resources. A country-based example is presented to illustrate some aspects of these issues and a few concluding remarks are provided. -
Book (stand-alone)Progress on water use efficiency - Global baseline for SDG 6 Indicator 6.4.1 2018
Also available in:
No results found.Access to safe water and sanitation and sound management of freshwater ecosystems are at the very core of sustainable development. This is the aim of Sustainable Development Goal 6 (SDG 6), which includes approaches to water management supported by international cooperation, capacity building and stakeholder participation. Indicator 6.4.1 has been designed to assess the economic and social use of water resources in terms of the value added when they are used in different sectors of the economy. Water-use efficiency is strongly influenced by a country’s economic structure, the proportion of water intensive sectors and any “real” improvements or deteriorations. Increasing water-use efficiency over time means decoupling economic growth from water use across the main water-using sectors, which are agriculture, industry, energy and municipal water supply. This report describes the methodology for the assessment of SDG indicator 6.4.1 on water use efficiency, illustrating its development in the pilot phase of the GEMI project and the technical steps needed to apply it. It passes to present the data collection process, and the role of the various national and international stakeholders in the monitoring process. Finally, the report shows the results of the first implementation of the indicator, defining its baseline and proposing key messages for the interpretation of the results.
