Understanding Farmers’ Adaptation to Water Scarcity


Book Description

This study was undertaken to analyze farmers’ adaption to water scarcity in the command area of a secondary canal in the Nile Delta of Egypt. The results revealed that farmers’ responses were driven by a multiplicity of factors, beyond water scarcity or profit maximization. These additional factors include food security of the family, risk management, social capital and history of farmers, and most unexpectedly the collective dimension of crop choice. The findings of this study expose the limitations of projects, modeling exercises or policy recommendations that are too often based on the oversimplified view of profit maximization as the basis of farming system dynamics.




Coping with Water Scarcity


Book Description

The report aims to provide a conceptual framework to address food security under conditions of water scarcity in agriculture. It has been prepared by a team of FAO staff and consultants in the framework of the project "Coping with water scarcity - the role of agriculture", and has been discussed at an Expert Consultation meeting organized in FAO, Rome, during the period 14-16 December 2009 on the same subject. It was subsequently edited and revised, taking account of discussions in the Expert Consultation and materials presented to the meeting. The purpose of the Expert Consultation was to assist FAO to better design its water scarcity programme. In particular, the experts were requested to provide recommendations on the range of technical and policy options and associated principles that FAO should promote as part of an agricultural response to water scarcity in member countries. The document offers views on the conceptual framework on which FAO's water scarcity programme should be based, proposes a set of definitions associated with the concept of water scarcity, and indicates the main principles on which FAO should base its action in support to its member countries. At the meeting, experts were requested to review the draft document and provide feedback and recommendations for its finalization. Issues that were addressed in discussions included: 3⁄4 Water scarcity: agreement on key definitions. 3⁄4 The conceptualisation of water scarcity in ways that are meaningful for policy development and decision-making. 3⁄4 The quantification of water scarcity. . 3⁄4 Policy and technical response options available to ensure food security in conditions of water scarcity. . 3⁄4 Criteria and principles that should be used to establish priorities for action in response to water scarcity in agriculture and ensure effective and efficient water scarcity coping strategies.




Farmer Behaviour, Agricultural Management and Climate Change


Book Description

This study examines the broad range of factors driving farm management decisions that can improve the environment, including drawing on the experiences of OECD countries.

Water Supply and Water Scarcity


Book Description

This Book includes selected papers that has been published in the Water journal Special Issue (SI) on Water Supply and Water Scarcity. Moreover, an overview of the SI is included. The papers selected for publication in the SI include review and research papers on water history, on water management issues under water scarcity regimes, on rainwater harvesting, on water quality and degradation, and on climatic variability impacts on water resources. Overall, the issue identify and highlight the main challenges in water sector, and particularly in management and protection of water resources and in use of alternative (non-conventional) water resources, especially in areas with demographic change and climate vulnerability in order to achieve sustainable and secure water supply. Furthermore, general guidelines and possible solutions for an improved and sophisticated water management system are proposed and discussed, such as the adoption of advanced technological solutions and practices that improve water-use efficiency and the use of alternative water resources, to address the growing environmental and health issues and to reduce the emerging conflicts among water users.




A Ricardian Analysis of the Impact of Climate Change on African Cropland


Book Description

This study examines the impact of climate change on cropland in Africa. It is based on a survey of more than 9,000 farmers in 11 countries: Burkina Faso, Cameroon, Egypt, Ethiopia, Ghana, Kenya, Niger, Senegal, South Africa, Zambia, and Zimbabwe. The study uses a Ricardian cross-sectional approach in which net revenue is regressed on climate, water flow, soil, and economic variables. The results show that net revenues fall as precipitation falls or as temperatures warm across all the surveyed farms. In addition to examining all farms together, the study examined dryland and irrigated farms separately. Dryland farms are especially climate sensitive. Irrigated farms have a positive immediate response to warming because they are located in relatively cool parts of Africa. The study also examined some simple climate scenarios to see how Africa would respond to climate change. These uniform scenarios assume that only one aspect of climate changes and the change is uniform across all of Africa. In addition, the study examined three climate change scenarios from Atmospheric Oceanic General Circulation Models. These scenarios predicted changes in climate in each country over time. Not all countries are equally vulnerable to climate change. First, the climate scenarios predict different temperature and precipitation changes in each country. Second, it is also important whether a country is already hot and dry. Third, the extent to which farms are irrigated is also important.




Water Conservation, Reuse, and Recycling


Book Description

In December 2002, a group of specialists on water resources from the United States and Iran met in Tunis, Tunisia, for an interacademy workshop on water resources management, conservation, and recycling. This was the fourth interacademy workshop on a variety of topics held in 2002, the first year of such workshops. Tunis was selected as the location for the workshop because the Tunisian experience in addressing water conservation issues was of interest to the participants from both the United States and Iran. This report includes the agenda for the workshop, all of the papers that were presented, and the list of site visits.




Societal Adaptation to Climate Variability and Change


Book Description

Changes in climate and climate variability have an effect on people's behaviour around the world, and public institutions have an important part to play in influencing our ability to respond to and plan for climate risk. We may be able to reduce climate risk by seeking to mitigate the threat on the one hand, and by adapting to a changed climate on the other. Another theme of the book is the integrated role of adaptation and mitigation in framing issues and performing analyses. Adaptation costs fall most heavily on the poor and special attention needs to be paid to adaptation by the poorest populations. An integrating framework is also presented to provide the context for an expansive typology of terms to apply to adaptation. The 12 papers collected here use methods from a variety of disciplines and focus on different time frames for decision making, from short term to the very long term. Readership: Technically trained readers familiar with the policy issues surrounding climate change and interested in learning the scientific underpinnings of issues related to societal adaptation.




Climate Change, Water and Food Security
