Download or read book The Indus Basin of Pakistan written by Winston H. Yu and published by World Bank Publications. This book was released on 2013 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study, Indus basin of Pakistan: the impacts of climate risks on water and agriculture was undertaken at a pivotal time in the region. The weak summer monsoon in 2009 created drought conditions throughout the country. This followed an already tenuous situation for many rural households faced with high fuel and fertilizer costs and the impacts of rising global food prices. Then catastrophic monsoon flooding in 2010 affected over 20 million people, devastating their housing, infrastructure, and crops. Damages from this single flood event were estimated at US dollar 10 billion, half of which were losses in the agriculture sector. Notwithstanding the debate as to whether these observed extremes are evidence of climate change, an investigation is needed regarding the extent to which the country is resilient to these shocks. It is thus timely, if not critical, to focus on climate risks for water, agriculture, and food security in the Indus basin of Pakistan.
Download or read book The Irrigation Sector written by and published by World Bank Publications. This book was released on 1999 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: India's irrigated agriculture sector has been basic to India's economic development and poverty alleviation. One of India's major achievements is its rapid expansion of irrigation and drainage infrastructure. However, the major emphasis on development has been achieved at a cost. The importance put on new construction has diverted attention away from the need to ensure the quality, productivity, and sustainability of the services. Further, a governmental subsidy based approach has been used and this has resulted in irrigation and drainage services which, while enabling significantly higher productivity than from non-irrigated lands, are well below their potential. 'The Irrigation Sector' discusses directions for future growth, the framework for reform, and the reform agenda.
Download or read book Irrigated Agriculture in Egypt written by Masayoshi Satoh and published by Springer. This book was released on 2017-03-07 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book targets the issue of water scarcity in Egypt as a typical example of the world water crisis. Today, the available water resource is facing its limit because of rapid increase in water demand as a result of population growth and changes in peoples’ life-style. The basic idea to solve the problem of water scarcity is that the irrigation sector, the biggest user of water, should increase water use efficiency. However, the real problem is how this can be achieved in view of the crucial need for water in this sector. This book addresses this challenge through case studies from the Nile delta in Egypt. The water problem in the Nile delta, the major source for water in Egypt, is discussed in this book from all its various aspects. This book covers the situation before and after the advent of the Aswan High Dam, so that the reader understands the entire development. Another special feature are the extensive and scientific descriptions of contemporary topics in water and agriculture, especially from the viewpoint of water saving and sustainability. These descriptions are based on field experiments and surveys in a six-year international research project. Topics of this book are local, but their implications are global.
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 Modernisation Strategy for National Irrigation Systems in the Philippines written by Mona Liza F. Delos Reyes and published by CRC Press. This book was released on 2017-07-12 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents documentary evidence of the insufficiency of rehabilitation works to close the gap between the irrigation service and actual area irrigated of publicly funded national irrigation systems in the Philippines. It outlines a methodology for formulating a modernisation plan for national irrigation systems with focus on the mostly ungauged, medium to small canal irrigation systems. The proposed methodology adaptively modified some known modernisation concepts and techniques and integrated them in a more holistic framework in the context of changing weather patterns and river flow regimes. It includes in-depth review of rehabilitation works; system diagnosis; revalidation of design assumptions on percolation and water supply; characterisation of system management, irrigation service and demand; and drawing up of options and a vision for the modernised irrigation systems. Central to the proposed modernisation strategy is the logical coherence among the design of physical structures, system operation and water supply so that improvements of irrigation service are possible. The book discusses the development of the proposed methodology and demonstrates its utility in two case study irrigation systems.

Available in PDF, EPUB and Kindle. Book excerpt: This is volume 2 of a two-volume work. It discusses a set of ten sectoral plans about natural environment, agriculture and husbandry, urban environment and social welfare, infrastructures and mobility, cultural heritage, tourism and public use, landscape, sustainability, socio-demography, economic development and governance. The sectoral plans are accompanied by eighteen pilot projects that develop in detail their most sensitive or relevant parts. The book is intended for planners and researchers from various disciplines, including urban planning, forestry, agriculture, cultural and touristic management, and sustainability studies. The book presents a unique example of integral planning at different scales and across different types of landscapes found on the outskirts of metropolitan areas. It features a sustainability orientated integrated plan to maximise the performance of the south-central area of the Calderona Mountain Range, Spain (Sierra Calderona). It is informed and driven by social, cultural, perceptual, sustainability and economic factors supported by a participative process, acknowledging the frequent conflict between the natural and cultural values found there and the strong pressure for transformation and public use. Incorporating new methodologies and graphical systems for regional and local planning, it constitutes an example of balanced and multidisciplinary planning, based on principles of sustainability, system thinking, new governance and local adaptation.

Download or read book Digest of Ethiopia s National Policies Strategies and Programs written by Yamāh̲barāwi ṭenāt madrak (Ethiopia) and published by African Books Collective. This book was released on 2008 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having just emerged from a prolonged civil war and faced with the urgent tasks of establishing political stability and reinvigorating an economy in tatters, the Transitional Government of Ethiopia (1991-1995) had to set a new direction for the economic reconstruction and social rehabilitation of the warn-torn and poverty-ridden country. During the Transitional Period a spate of new policies and strategies defining the development priorities, goals and implementation instruments of the new regime led by the EPRDF was introduced. This work is a synthesis of various sectoral policies and an attempt to trace the genesis of the policies, highlight the continuities, significant departures and other salient features. Each of the reviews in this digest briefly analyses the critical elements of the policies, identifies major gaps in the conceptualisation of the policy as well as the achievements registered and the challenges encountered in its implementation. The authors also try to identify the outstanding issues to be addressed by policymakers and suggest remedies. The policy reviews have been grouped into three parts and presented under social, economic and governance sectors.

Download or read book Costs and Performance of Irrigation Projects written by Arlene B. Inocencio and published by IWMI. This book was released on 2007 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: High irrigation investment costs together with declining world prices for food and the failures of a number of high profile past irrigation projects are the main reasons for the reluctance of development agencies and governments in sub-Saharan Africa to invest more resources in irrigation. This study aims to systematically establish whether costs of irrigation projects in sub-Saharan Africa are truly high, determine the factors which influence costs and performance of irrigation projects, and recommend cost-reducing and performance-enhancing options to make irrigation investments in the region more attractive. It analyzes 314 irrigation projects implemented from 1967 to 2003 in 50 countries in Africa, Asia, and Latin America funded by the World Bank, African Development Bank and the International Fund for Agricultural Development.
