Download or read book Unlocking the Water Potential of Agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2003 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: All statistical evidence confirms that agriculture is the key sector for water management, now and in the next decades. Nevertheless, the rural water development sector fails at present to get priority, compared to other competing sectors, in international fora. Strong and new arguments are needed to bring rural water back "on line." Agriculture policies and investments will need to become more strategic. They will have to unlock the potential of agricultural water management practices to raise productivity, spread equitable access to water, and conserve the natural productivity of water resources base.

Download or read book More Crop Per Drop written by Meredith Giordano and published by IWA Publishing. This book was released on 2007-01-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Water Management for Sustainable Food Production written by Narayanan Kannan and published by . This book was released on 2020 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The agricultural community is face with the challenge of increasing food production by more than 70% to meet demand from the global population increase by the mid-21st century. Sustainable food production involves the sustained availability of resources, such as water and energy, to agriculture. The key challenges to sustainable food production are population increase, increasing demands for food, climate change, climate variability, and decreasing per capita land and water resources. To discuss more details on (a) the challenges for sustainable food production and (b) mitigation options available, a Special Issue on “Water Management for Sustainable Food Production” was assembled. This Special Issue focused on issues such as irrigation using brackish water, virtual water trade, allocation of water resources, consequences of excess precipitation on crop yields, strategies to increase water productivity, rainwater harvesting, irrigation water management, deficit irrigation, fertilization, environmental and socio-economic impacts, and irrigation water quality. The articles in the Special Issue cover several water-related issues across the U.S., Asia, Middle East, Africa, and Pakistan concerning sustainable food production. The articles in this Special Issue highlight the substantial impacts on agricultural production, water availability, and water quality in the face of increasing demands for food and energy.
Download or read book The Impact of Irrigation on Nutrition Health and Gender written by Laia Domenech and published by Intl Food Policy Res Inst. This book was released on 2013-04-11 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture in Africa south of the Sahara (SSA) is still largely rainfed. SSA also exhibits the lowest crop yields for major staples in the world, largely due to low use of irrigation and fertilizer. Rainfed agriculture poses growing production risks with increased climate variability and change. At the same time, smallholder irrigation in the region developed rapidly over the past decade, albeit starting from very low levels. In addition to largely demand-driven irrigation development by smallholders, there is a significant push by donors for large-scale irrigation development, as well as some push for smallholder irrigation. There has also been a long-standing debate about whether irrigation in SSA should be large scale or small scale to achieve its potential. However, given the potentially high rewards, but also high possibility of failure, the assessment of irrigation potential must go beyond large scale versus small scale to integrate concerns regarding environmental sustainability, resource use efficiency, nutrition and health impacts, and womens empowerment. The hypothesis underlying this review paper is that how irrigation gets deployed in SSA will be decisive not only for environmental sustainability (such as deciding remaining forest cover in the region) and poverty reduction, but also for health, nutrition, and gender outcomes in the region. The focus of this paper is on the health, nutrition, and gender linkage. We find that to date, few studies have analyzed the impact of irrigation interventions on nutrition, health, and womens empowerment, despite the large potential of irrigation to affect these important variables. Irrigation interventions may have differential effects on different members in the household and in the community, such as irrigators, non-irrigators, children, and women. Measuring and understanding such differences, followed by improving design and implementation to maximize gender, health, and nutrition outcomes, could transform irrigation programs from focusing solely on increased food production toward becoming an integral component of poverty-reduction strategies.

Download or read book The State of the World s Land and Water Resources for Food and Agriculture written by Food and Agriculture Organization of the United Nations and published by Routledge. This book was released on 2013-06-17 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The State of the World's Land and Water Resources for Food and Agriculture is FAO's first flagship publication on the global status of land and water resources. It is an 'advocacy' report, to be published every three to five years, and targeted at senior level decision makers in agriculture as well as in other sectors. SOLAW is aimed at sensitizing its target audience on the status of land resources at global and regional levels and FAO's viewpoint on appropriate recommendations for policy formulation. SOLAW focuses on these key dimensions of analysis: (i) quantity, quality of land and water resources, (ii) the rate of use and sustainable management of these resources in the context of relevant socio-economic driving factors and concerns, including food security and poverty, and climate change. This is the first time that a global, baseline status report on land and water resources has been made. It is based on several global spatial databases (e.g. land suitability for agriculture, land use and management, land and water degradation and depletion) for which FAO is the world-recognized data source. Topical and emerging issues on land and water are dealt with in an integrated rather than sectoral manner. The implications of the status and trends are used to advocate remedial interventions which are tailored to major farming systems within different geographic regions.

Download or read book Water for Food in a Changing World written by Alberto Garrido and published by Routledge. This book was released on 2011-04-12 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is not enough water globally for all the things humans need and want water to do for us. Water supply bubbles are bursting in China, the Middle East and India with potentially serious implications for the global economy and for political stability. Even the United States is depleting groundwater on average 25% faster than it is being replenished. Our thirst for water grows with our population, but the amount of fresh water available on Earth is fixed. If we assume "business as usual" by 2050 about 40% of the projected global population of 9.4 billion is expected to be facing water stress or scarcity. With increasing climate variability being predicted by global climate models, we are likely also to have more people without adequate water more of the time, even in water-rich regions. Irrigation productivity rose dramatically over the past 40 years as a result of the Green Revolution. However, even if we disregard the environmental impacts caused by that revolution, we are no nearer to achieving global food security than we were 40 years ago, as every time we come close to filling the food production gap population growth and ecosystem decline associated with water diversions to human purposes set us back. Our natural and agricultural ecosystems are trying to tell us something. This book pursues these overarching themes connecting to water and food production at global and regional scales. The collection offers a comprehensive discussion of all relevant issues, and offers a wide-ranging discussion with the aim of contributing to the global debate about water and food crises.
Download or read book Food Energy and Water Nexus written by Chittaranjan Ray and published by Springer Nature. This book was released on 2022-01-17 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, major issues surrounding importance of water and energy for food security in the United States and India are described representing two extremes in yield, irrigation efficiency, and automation. The farming systems in these two countries face different risks in terms of climatic shifts and systems’ resiliency to handle the shocks. One may have comparative advantage over the other, but both are susceptible. Innovations in irrigation for food and fuel production, improvements in nitrogen and water use efficiency, and rural sociological issues are discussed here. We also look into some of the unintended consequences of high productivity agriculture in terms of surface and ground water quality and impacts on ecosystem services. Finally, we present ways to move forward to meet the food demands in the next half-century in both countries. As the current world population of 7 billion is expected to reach or exceed 10 billion in the next 40 years, there will be significant additional demand for food. A rising middle class and its preference for a meat-based diet also increases the demand for animal feed. This additional food and feed production needs special considerations in water and energy management besides the development of appropriate crop hybrids to withstand future climatic shifts and other environmental factors. A resilient agricultural landscapes will also be needed to withstand climatic fluctuations, disease pressures, etc. While the upper and many middle income countries have made significant improvements in crop yield due to pressurized irrigation and automation in farming systems, the lower income countries are struggling with yield enhancements due to such limitations. The rise in population is expected to be more in Sub-Sharan Africa and Middle East (Low to middle-income countries) where the crop yields are expected to be low.
