Download or read book Guidance on realizing real water savings with crop water productivity interventions written by Van Opstal, J., Droogers, P., Kaune, A., Steduto, P., Perry, C. and published by Food & Agriculture Org.. This book was released on 2021-03-18 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical document contains clear and practical guidelines on how to implement real water savings in agriculture through interventions for enhancing crop water productivity. A distinction is made between real water savings and “apparent” water savings. Apparent water savings record reductions in water withdrawals but do not account for changes in water consumption. Real water savings record reductions in water consumption and non-recoverable return flows (runoff or percolation). This guidance document emphasizes the paradox of water savings at field and basin scales, which usually do not translate into increased water availability for other users, as is commonly believed.
Download or read book Capacity Development in Irrigation and Drainage written by International Commission on Irrigation and Drainage and published by Food & Agriculture Org.. This book was released on 2004 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consensus among policy-makers in the developing world and aid agencies is that a lack of capacity is constraining the development of irrigated agriculture. Although this concern is not new, it is now receiving much attention in the irrigation and drainage world, where it is becoming an issue in its own right rather than being embedded in infrastructure investment projects. In order to address this issue FAO Land and Water Development Division (AGL) organized a one-day workshop , which brought together a range of case studies from different parts of the world in order to demonstrate that capacity development should be central focus of future strategies on irrigation and drainage. This publication contains a synthesis of the workshop as well as three keynote papers prepared for the workshop based on the available literature and experiences. The complete workshop materials, which include several country papers and complementary documents, are included on a CD-ROM that accompanies this document
Download or read book The AquaCrop model Enhancing crop water productivity written by Salman, M., García-Vila, M., Fereres, E., Raes, D., Steduto, P. and published by Food & Agriculture Org.. This book was released on 2021-11-16 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources are linked to the global challenges of food insecurity and poverty, as well as to climate change adaptation and mitigation. In line with the Sustainable Development Goals (SGD), FAO works towards several dimensions of sustainable development, including the promotion of coherent approaches to efficient, productive and sustainable water management, from farm to river basin scales. Accordingly, FAO is enhancing well-informed on-the-ground decision-making processes on water management through projects, knowledge advancement, information-sharing and tools development, such as AquaCrop, the FAO crop-water productivity model. This model assists in assessing the effects of environment (including atmospheric CO2 concentration) and management on crop production through the simulation of yield response to water of herbaceous crops. It is particularly suited to address conditions where water is a key limiting factor in crop production. In 2009, FAO officially launched AquaCrop, being the result of several years of collaborative work among scientists, water and crop specialists and practitioners worldwide, bringing together previously fragmented information on crop yields in response to water use and water deficit. AquaCrop has evolved over the different versions released since its first launch, but it always balances accuracy, simplicity and robustness. This has enabled it to remain faithful to its goal, i.e., to be a dynamic tool accessible to several types of users, mainly practitioner-type end users, in different disciplines and for a wide range of applications. In addition, AquaCrop may be considered a valuable tool by research scientists for analysis and conceptualization.

Download or read book Stakeholder oriented Valuation to Support Water Resources Management Processes written by Leon Hermans and published by Food & Agriculture Org.. This book was released on 2006 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, raising capacity in water resources management entails supporting stakeholders and decision-makers to reach a common understanding on the priorities and necessary arrangements for sharing and allocating water-related goods and services. Valuation is central to this process, as setting priorities and making choices implies valuing certain uses and arrangements above others. Water valuation can help stakeholders to express the values that water-related goods and services represent to them. It also offers a means for conflict resolution and planning, informing stakeholders, supporting communication, and facilitating joint decision-making on priorities and specific actions. This report confronts concepts from the literature on water valuation with practical experiences from three local cases where an effort was made to embed existing valuation tools and methods in ongoing water resources management processes. It uses the lessons from this exploration to provide a first outline for a stakeholder-oriented water valuation process. This is expected to provide a useful starting point to help water professionals and policy-makers improve the use of water valuation as a means to support participatory processes of water resources management.
Download or read book Deficit Irrigation Practices written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.
Download or read book Demand for Products of Irrigated Agriculture in Sub Saharan Africa written by P. J. Riddell and published by Food & Agriculture Org.. This book was released on 2006 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: If irrigated production is to make a significant contribution to food security and economic growth in Sub Saharan Africa, it will have to be re-structured across the region as a whole. This is the main conclusion of a study undertaken by FAO to analyse the drivers of demand for irrigated production in Sub-Saharan Africa (SSA). Steeply rising commercial food import bills for staple crops across SSA are indicative of the level demand that is not being met from domestic production. The increase of area under equipped/spate irrigation for the whole of Africa over the last ten years amounts to 1.27 million ha, which is equal to about 127 000 ha a year. This rate of growth has proved too low to have an impact on food import bills and buffer regional food security. However, within subregional trading groups there is scope for consolidation of market supply. Irrigated production opportunities in SSA could be realised where natural resources and markets coincide, but only through a great deal more attention to costs of production, price formation, effective water allocation mechanisms, economically efficient water use and strong, responsive institutions.

Download or read book Economic Valuation of Water Resources in Agriculture written by R. Kerry Turner and published by Food & Agriculture Org.. This book was released on 2004 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to produce a review on water resource valuation issues and techniques specifically for the appraisal and negotiation of raw (as opposed to bulk or retail) water resource allocation for agricultural development projects. The review considers raw water in naturally occurring watercourses, lakes, wetlands, soil and aquifers, taking an ecosystem function perspective at a catchment scale, and takes account of the demands from irrigated and rainfed agriculture. It is hoped that the review will have particular application to developing countries where agreed methods for reconciling competing uses are often absent, but nevertheless takes account of valuation approaches that have been made in post industrial economies.

Download or read book Rethinking the Approach to Groundwater and Food Security written by Marcus Moench and published by Food & Agriculture Org.. This book was released on 2003 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is important in agriculture as it provides a reliable fallback when rainfeeding fails. It is therefore instrumental in managing risk and optimizing food production. However accessing groundwater has become habit and turned to dependency. Resources limits on many key aquifers have been exceeded and competition for groundwater has become intense. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management.
