Accounting for Water Use and Productivity by David Molden Pdf

This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and increasing water productivity; developing a better understanding of present patterns of water use and impacts of interventions; improving communication among professionals and communication to non-water professionals; and improving the rationale for allocation of water among uses. It is expected that with further application, these water accounting concepts will evolve into a robust, supporting methodology for water basin analysis.

Accounting for livestock water productivity: How and why? by ​Drastig, K., Vellenga, L., Qualitz, G., Singh, R., Pfister, S., Boulay, A.-M., Wiedemann, S., Prochnow, A., Chapagain, A., De Camillis, C., Opio, C. & Mottet, A. Pdf

The assessment of water productivity in livestock supply chains has a critical role to play in developing productive and sustainable food production systems worldwide. In particular, the evaluation of water productivity improvement options is key to addressing growing food demand and the projected impacts of climate change under conditions where the availability of land and water resources is increasingly limited. In this report, we review current applications of water productivity analysis in livestock supply chains. To do so, we analysed 50 livestock water productivity studies carried out in various regions of the world from 1993 to the present time. We reviewed the assessment goals, system boundaries, methodological approaches, water flows, modelling tools, databases, livestock species and the main findings in each of the studies. We found that there was no consistency in the methods and approaches used to assess water productivity in livestock production chains. The studies varied widely in terms of their assessment goals, methodology, and the sources of water used for the analysis. The main methodological differences were the inclusion or exclusion of background processes, such as water input and the treatment of precipitation in accounting for water use in livestock production processes. Another key issue was the missing uncertainty assessment, which can be classified as input data uncertainty or model uncertainty, as well as choice uncertainties. The review recommends the further development of guidelines that ensure a consistent and coordinated application of water productivity analysis of livestock production systems world-wide.

Basin-level Use and Productivity of Water by David Molden,R. Sakthivadivel,Zaigham Habib Pdf

Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in nothern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

The Economics of Water Management in Southern Africa by Glenn-Marie Lange,Rashid M. Hassan,Jaap Arntzen,Jackie Crawford,Eric Mungatana Pdf

This book presents a valuable new tool for water management water resource accounting which significantly advances the economic analysis of water. Water resource accounts integrate detailed information about water supply and use with national income accounts to show the economic use of water, costs and tariffs paid, and the economic value of water for different economic uses. Based on the UN s handbook for environmental accounting, this book describes the implementation and policy application of water accounts in three African countries Botswana, Namibia and South Africa and discusses how they have been used by water managers. The book compares water use across the three countries, explaining the differences in water resources and water policy. In addition to the comprehensive outline of physical and monetary water accounts for each country, the authors provide an extensive discussion of water valuation as well as addressing a number of issues of regional importance, including water accounting for an international river basin and the impact of trade on each country s water use. By demonstrating the usefulness of water resource accounts, this book makes a major contribution to the literature on water economics and management, sustainable development, and to the development of environmental accounting in general. The Economics of Water Management in Southern Africa will appeal to a wide readership including: environmental and development economists NGOs concerned with sustainable development environmental advocacy groups professionals (economists and environmentalists) working in Africa on water and sustainable development issues water professionals national accounts experts and statisticians.

Water Use, Shadow Prices and the Canadian Business Sector Productivity Performance by Kais Dachraoui Pdf

This paper develops a production framework that allows for self-supplied water intake, an unpriced 'natural' input. The framework is then exploited to estimate the corresponding water shadow prices and to assess the extent to which water impacts on the multifactor productivity performance of the Canadian business sector's industries. Accounting for water intake leaves the aggregate business sector's multifactor productivity growth virtually unchanged over the 1981-1996 period, but it increases the productivity performance of the largest water-using industries by 0.7 percentage points on average. The shadow price of water intake amounts to $0.73 cubic meter and varies significantly across industries. While the introduction of water recirculation, a kind of water recycling, does not alter in a significant way most of these results, it reduces the shadow price estimate to $0.55 cubic meter and improves its reliability particularly for the largest water-using industries. Water is found to be a substitute to capital and labor inputs, suggesting that more of these inputs are required to bring about savings in water use.

Estimating Productivity of Water at Different Spatial Scales Using Simulation Modeling by Peter Droogers,G. W. Kite Pdf

A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

More Crop Per Drop by Meredith Giordano,Frank R. Rijsberman,R. Maria Saleth Pdf

This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.
