Book excerpt: Previous Ricardian analyses of agriculture have either omitted irrigation or treated irrigation as though it is exogenous. In practice, it is a choice by farmers that is sensitive to climate. This paper develops a choice model of irrigation in the context of a Ricardian model of cropland. The authors examine how climate affects the decision to use irrigation and then how climate affects the net revenues of dryland and irrigated land. This Ricardian "selection" model, using a modified Heckman model, is then estimated across 8,400 farmers in Africa. The analysis explicitly models irrigation but controls for the endogeneity of irrigation. The authors find that the choice of irrigation is sensitive to both temperature and precipitation. Simulations of the welfare impacts of several climate scenarios demonstrate that a model which assumes irrigation is exogenous provides a biased estimate of the welfare effects of climate change. If dryland and irrigation are to be estimated separately in the Ricardian model, irrigation must be modeled endogenously. The results also indicate that African agriculture is sensitive to climate change. Many farmers in Africa will experience net revenue losses from warming. Irrigated farms, on the other hand, are more resilient to temperature change and, on the margin, are likely to realize slight gains in productivity. But any reduction in precipitation will be especially deleterious to dryland farmers, generally the poorest segment of the agriculture community. The results indicate that irrigation is an effective adaptation against loss of rainfall and higher temperatures provided there is sufficient water available. This will be an effective remedy in select regions of Africa with water. However, for many regions there is no available surface water, so that warming scenarios with reduced rainfall are particularly deleterious.

Download or read book Sustainable Irrigation Development in the White Volta sub Basin written by Eric Antwi Ofosu and published by CRC Press. This book was released on 2011-12-16 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sub-Saharan Africa has an irrigation potential of about 42 million hectares of which only 17% is developed. Despite several investments in irrigation the growth is slow. This study aims at helping to achieve sustainable irrigation in sub-Saharan Africa, through gaining a better understanding of productive irrigation water use and effective management of irrigation development. The study is conducted in the White Volta sub-basin specifically in Northern Ghana and Southern Burkina Faso which have been experiencing rapid irrigation development since the mid 1990s. The study identified growing markets for irrigated products as an important driving force behind the expansion of irrigation which has given rise to new technologies. The new technologies have spread because they gave farmers direct control over water sources. These new technologies allow relatively small farm sizes which can be adequately managed by the surveyed farmers. As a result high productivities are achieved. The hydrological impact of upscaling irrigation in the sub-basin is sustainable and will maximize the overall benefits derived from water resources in the Volta Basin.

Book excerpt: Ô. . . this book is a very useful resource for the lawyer. . . makes a good start by presenting a wide-ranging portfolio of multidisciplinary research that will assist in progressing the task, challenging though it may be.Õ Ð Chris Rodgers, Environmental Liability This book explores the interaction between climate change and the agriculture sector. Agriculture is essential to the livelihood of people and nations, especially in the developing world; therefore, any impact on it will have significant economic, social, and political ramifications. Scholars from around the world and from various fields have been brought together to explore this important topic. The contributions found here analyze direct agronomic effects, the economic impacts on agriculture, agricultural impacts on the economy, agricultural mitigation, and farmer adaptation. The authors argue that climate change is likely to have an extensive impact on agriculture around the world through changes in temperature, precipitation, concentrations of carbon dioxide, and available water flows. This thorough and timely volume is an invaluable resource for anyone interested in exploring the impacts of climate change in arguably the most important sector of the world economy. Economists, agronomists, and climate modelers in academia and the public sector, policy analysts and development agency staff, and graduate/postgraduate students will find this remarkable volume a welcome addition to their collection.
Download or read book Arid Lands Water Evaluation and Management written by Robert Maliva and published by Springer Science & Business Media. This book was released on 2012-06-09 with total page 1068 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large part of the global population lives in arid lands which have low rainfall and often lack the water required for sustainable population and economic growth. This book presents a comprehensive description of the hydrogeology and hydrologic processes at work in arid lands. It describes the techniques that can be used to assess and manage the water resources of these areas with an emphasis on groundwater resources, including recent advances in hydrologic evaluation and the differences between how aquifer systems behave in arid lands versus more humid areas. Water management techniques are described and summarized to show how a more comprehensive approach to water management is required in these areas, including the need to be aware of cultural sensitivities and conditions unique to many arid regions. The integration of existing resources with the addition of new water sources, such as desalination of brackish water and seawater, along with reusing treated wastewater, will be required to meet future water supply needs. Also, changing climatic conditions will force water management systems to be more robust so that future water supply demands can be met as droughts become more intense and rainfall events become more intense. A range of water management techniques are described and discussed in order to illustrate the methods for integrating these measures within the context of arid lands conditions.
Download or read book Water management policies and their impact on irrigated crop production in the Murray Darling Basin Australia written by Burdack, Doreen and published by Universitätsverlag Potsdam. This book was released on 2015-06-09 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The economic impact analysis contained in this book shows how irrigation farming is particularly susceptible when applying certain water management policies in the Australian Murray-Darling Basin, one of the world largest river basins and Australia’s most fertile region. By comparing different pricing and non-pricing water management policies with the help of the Water Integrated Market Model, it is found that the impact of water demand reducing policies is most severe on crops that need to be intensively irrigated and are at the same time less water productive. A combination of increasingly frequent and severe droughts and the application of policies that decrease agricultural water demand, in the same region, will create a situation in which the highly water dependent crops rice and cotton cannot be cultivated at all.

Download or read book Seasonality Rural Livelihoods and Development written by Stephen Devereux and published by Routledge. This book was released on 2013-07-03 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seasonality is a severe constraint to sustainable rural livelihoods and a driver of poverty and hunger, particularly in the tropics. Many poor people in developing countries are ill equipped to cope with seasonal variations which can lead to drought or flood and consequences for agriculture, employment, food supply and the spread of disease. The subject has assumed increasing importance as climate change and other forms of development disrupt established seasonal patterns and variations. This book is the first systematic study of seasonality for over twenty years, and it aims to revive academic interest and policy awareness of this crucial but neglected issue. Thematic chapters explore recent shifts with profound implications for seasonality, including climate change, HIV/AIDS, and social protection. Case study chapters explore seasonal dimensions of livelihoods in Africa (Ethiopia, Kenya, Malawi), Asia (Bangladesh, China, India), and Latin America (Peru). Others assess policy responses to adverse seasonality, for example through irrigation, migration and seasonally-sensitive education. The book also includes innovative tools for monitoring seasonality, which should enable more appropriate responses.

This book was released on 2012-12-06 with total page 930 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jan van Schilfgaarde, USDA Agricultural Research Service and National Research Council Committee on Irrigation-Induced Water Quality Problems In 1982, a startling discovery was made. Many waterbirds in Kesterson National Wildlife Refuge were dying or suffering reproductive failure. Located in the San Joaquin Valley (Valley) of California, the Kesterson Reservoir (Kesterson) was used to store agricultural drainage water and it was soon determined that the probable cause of the damage to wildlife was high concen trations of selenium, derived from the water and water organisms in the reservoir. This discovery drastically changed numerous aspects of water management in California, and especially affected irrigated agriculture. In fact, the repercussions spilled over to much of the Western United States. For a century, water development for irrigation has been a religiously pursued means for economic development of the West. The primary objective of the Reclamation Act of 1902 was, purportedly, the development ofirrigation water to support family farms which, in turn, would enhance the regional economy (Worster, 1985).

Download or read book Pricing Irrigation Water written by Yacov Tsur and published by Routledge. This book was released on 2010-09-30 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: As globalization links economies, the value of a country's irrigation water becomes increasingly sensitive to competitive forces in world markets. Water policy at the national and regional levels will need to accommodate these forces or water is likely to become undervalued. The inefficient use of this resource will lessen a country's comparative advantage in world markets and slow its transition to higher incomes, particularly in rural households. While professionals widely agree on what constitutes sound water resource management, they have not yet reached a consensus on the best ways of implementing policies. Policymakers have considered pricing water - a debated intervention - in many variations. Setting the price 'right,' some say, may guide different types of users in efficient water use by sending a signal about the value of this resource. Aside from efficiency, itself an important policy objective, equity, accessibility, and implementation costs associated with the right pricing must be considered. Focusing on the examples of China, Mexico, Morocco, South Africa, and Turkey, Pricing Irrigation Water provides a clear methodology for studying farm-level demand for irrigation water. This book is the first to link the macroeconomics of policies affecting trade to the microeconomics of water demand for irrigation and, in the case of Morocco, to link these forces to the creation of a water user-rights market. This type of market reform, the contributors argue, will result in growing economic benefits to both rural and urban households.
Download or read book Water Reuse written by Chris Binnie and published by IWA Publishing. This book was released on 2008-05-14 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differently wastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater. In the first section water reuse practices around the world are described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view. Each reuse purpose demands different water quality, not only to protect health and the environment but also to fulfil the requirements of the specific reuse. Reuses considered are agricultural, urban agriculture as a special case of the former, municipal and industrial. Alongside these uses, the indirect reuse for human consumption through aquifer recharge is also discussed. The third section deals with emerging and controversial topics. Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as the different international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered. The fourth section of the book presents contrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse. Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for human consumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for regulating water reuse in several countries, the Mediterranean situation is described. Other case studies presented refer to the reuse situation in Israel, Spain, Cameroon, Nepal and Vietnam, these latter countries being located in water rich areas. This book will be an invaluable information source for all those concerned with water reuse including water utility managers, wastewater policy makers and water resources planners as well as researchers and students in environmental engineering, water resources planning and sanitary engineering.

Download or read book Micro and Macro level Approaches for Assessing the Value of Irrigation Water written by Robert C. Johansson and published by World Bank Publications. This book was released on 2005 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Many countries are reforming their economies and setting macroeconomic policies that have direct and indirect impact on the performance of the irrigation sector. One reason for the movement toward reform in the water sector across countries is that water resources are increasingly becoming a limiting factor for many human activities. Another reason for increased pressures to address water policy issues is that many countries are in the process of removing barriers to trade, particularly in agricultural commodities. Therefore, knowledge of the value of water when crafting domestic and macroeconomic policies is important to compare the variable impacts of reform across sectors of the economy and populations within the country. Researchers have used many methods for assessing the value of irrigation water. This survey reviews a broad literature to ascertain how two basic questions have been addressed by research over the past few decades. First, what is the value of water across different sectors and levels? Second, how will this value change under different macroeconomic and domestic policies? This survey details a number of methods for approaching these two questions. The literature has been organized according to a progression from theoretical underpinnings to empirical approaches to how the value of irrigation services are relevant to the link between globalization and poverty.

This book was released on 2017-12-15 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is expected to face increasing water risks that will impact production, markets, trade and food security - risks that can be mitigated with targeted policy actions on water hotspots. This report develops the hotspot approach, provides an application at the global scale, and presents a mitigation policy action plan. The People’s Republic of China, India and the United States are identified as countries facing the greatest water risks for agriculture production globally. A global simulation shows that, in the absence of action, water risks in Northeast China, Northwest India and the Southwest United States in particular could have significant production, price and trade consequences. Agriculture water risks could also result in broader socio-economic and food security concerns. Farmers, agro food companies, and governments can all play a role in responding to water risks at hotspot locations. A three-tier policy action plan is proposed to confront water risk hotspots, encompassing targeted responses, adapted national policies, strengthened market integration and international collaboration.
