This book was released on 2010-05-13 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be valued. The worth of these findings cannot be underestimated as the results are useful to those who need to allocate scarce water supplies between competing uses within a catchment. The assumptions underlying the model, the data used and the results and implications drawn are fully detailed in this paper. This model was connected to a hydrological model and used to simulate various scenarios on the water situation facing users in the basin. This model is the forerunner of similar modeling attempts on similar problems in other regions of the Krishna Basin and in the Murray Darling Basin of Australia.
Book Synopsis A case for pipelining water distribution in the Narmada Irrigation System in Gujarat, India by : Shah, Tushaar
Download or read book A case for pipelining water distribution in the Narmada Irrigation System in Gujarat, India written by Shah, Tushaar and published by IWMI. This book was released on 2011-02-08 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thanks to farmers’ resistance to provide land for constructing watercourses below the outlets, India’s famous Sardar Sarovar Project is stuck in an impasse. Against a potential to serve 1.8 million hectares, the Project was irrigating just 100,000 hectares five years after the dam and main canals were ready. Indications are that full project benefits will get delayed by years, even decades. In this paper, IWMI researchers advance ten reasons why the Project should abandon its original plan of constructing open channels and license private service providers to invest in pumps and buried pipeline networks to sell irrigation service to farmers.
Book Synopsis Health impacts of small reservoirs in Burkina Faso by : Eline Boelee
Download or read book Health impacts of small reservoirs in Burkina Faso written by Eline Boelee and published by IWMI. This book was released on 2010-02-02 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Burkina Faso, at least 1,700 small reservoirs have been constructed, most of them during the last 30 years. Numerous and scattered, these beneficial multipurpose systems combine productive with domestic water uses. However, their environmental and health impacts remain insufficiently documented. This report combines data from different sources into syntheses and national maps, with a focus on water-related diseases. The mitigation of negative impacts requires an integrated approach to specifically identify the enhancing and limiting factors that influence environmental impacts and the transmission of diseases around reservoirs. Public awareness campaigns need to accompany the promotion of preventive and curative measures and the development of alternative water sources for domestic supply.
Book Synopsis A Comparative Analysis of the Technical Efficiency of Rain-fed and Smallholder Irrigation in Ethiopia by : Makombe, G.
Download or read book A Comparative Analysis of the Technical Efficiency of Rain-fed and Smallholder Irrigation in Ethiopia written by Makombe, G. and published by IWMI. This book was released on 2011-08-02 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation – modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains can be made by raising the frontier of the traditional systems and increasing the efficiency of the modern systems. Among the production constraints studied were land preparation, soil fertility, weed control, pests and diseases, soil erosion, input access and moisture deficiency. The most significant constraints on the irrigated systems were input access and moisture deficiency.
Book Synopsis From Mesopotamia to the third millennium: the historical trajectory of water development and use in the Karkheh River Basin, Iran by : Sara Marjanizadeh
Download or read book From Mesopotamia to the third millennium: the historical trajectory of water development and use in the Karkheh River Basin, Iran written by Sara Marjanizadeh and published by IWMI. This book was released on 2010-05-13 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Karkheh River Basin is the third largest basin in Iran after Karoon and Dez, and occupies a strategic position on the western boundary of the country. The basin has seen remarkable ancient feats of engineering, and has a long history of wheat and barley production, complemented by horticulture. With the growth of the modern nation-state of Iran, water development has progressed steadily in tandem with rising populations and urbanization. The report aims to understand the historical setting and present situation of water development and allocation, in relation to rural development and agrarian policy. It provides the contextual backdrop for further research on the management of water to improve livelihoods in the basin through integrated and sustainable management of land and water resources. It provides further information on the changes in surface flows out of the component subbasins and looks at the development, use and consequences of groundwater abstraction.

The river basin studies helped policy formulation for integrated planning and management of water resources besides the methodological contribution through the development of appropriate tools for water management studies. It also contributed to enhancing the capabilities of agency officials and local researchers through their involvement in research activities.
Book Synopsis Climate change impacts and adaptation in Nepal by : Bartlett, R.
Download or read book Climate change impacts and adaptation in Nepal written by Bartlett, R. and published by IWMI. This book was released on 2010-12-29 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of climate change (CC) on water resources is likely to affect agricultural systems and food security. This is especially true for Nepal, a least developed country, where a high percentage of the population is dependent on agriculture for its livelihoods. It is thus crucial for Nepal’s leaders and resource managers to draft and begin implementing national adaptation plans. This working paper aims to create a more comprehensive understanding of how the impacts of CC will be realized at different scales in Nepal, from household livelihoods to national food security, and the many institutions governing the ultimate adaptation process.
Book Synopsis Agricultural extension in Central Asia: existing strategies and future needs by : Kazbekov, Jusipbek
Download or read book Agricultural extension in Central Asia: existing strategies and future needs written by Kazbekov, Jusipbek and published by IWMI. This book was released on 2011-12-19 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is at the forefront of the development objectives of the republics of Central Asia (CA). Since independence in 1991, these countries have undergone transitions from being centrally planned economies to market-oriented systems, which did not include the creation of agricultural extension systems. This paper provides information on the current status of the agricultural extension systems in CA with special reference to Kyrgyzstan, Tajikistan and Uzbekistan. We reviewed the existing extension strategies, donor- and state-driven initiatives to revitalize the agricultural extension systems, informal linkages that nongovernmental organizations play in helping a limited number of farmers, and provided recommendations on ways to further improve the agricultural extension services in CA. The information related to each country was analyzed separately. This is because, after independence, each republic in CA had initiated their agricultural reforms with specific objectives and has now established their unique agricultural systems that differ contextually. However, due to having the same history and agricultural system that existed during the Soviet times, we tried to give a historical perspective to the unified agricultural extension system that existed before independence.
Book Synopsis Inventory of water storage types in the Blue Nile and Volta River Basins by : Johnston, Robyn M.
Download or read book Inventory of water storage types in the Blue Nile and Volta River Basins written by Johnston, Robyn M. and published by IWMI. This book was released on 2010-10-08 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: For agriculture there is a continuum of water storage options, ranging from groundwater aquifers, soil water, natural wetlands and small ponds and tanks to large reservoirs. In any situation each of these has its own niche in terms of technical feasibility, socioeconomic sustainability and impact on public health and the environment. Planning storage requires insight into impending needs and also a good understanding of what already exists and what was, and was not, successful, in the past. This report provides an inventory of existing and prospective water storage in the Ghanaian Volta and the Ethiopian Blue Nile basins. It provides as much quantitative data as possible, but highlights both the dearth of readily available information and the lack of integrated planning of storage in both basins. Recommendations are made for improved planning in the future.
Book Synopsis An Overview of the Development Challenges and Constraints of the Niger Basin and Possible Intervention Strategies by : Regassa E. Namara
Download or read book An Overview of the Development Challenges and Constraints of the Niger Basin and Possible Intervention Strategies written by Regassa E. Namara and published by IWMI. This book was released on 2011-09-14 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Niger River Basin covers 7.5% of the African continent and is shared between nine riparian countries. The human population of the basin is growing at an average annual rate of about 3%, which makes the Niger River Basin one of the areas with the highest fertility rates in the world. The desert margin is expanding; climate change is negatively impacting rainfall; and urbanization, industrialization, and the human and livestock population are threatening the quantity and quality of available water resources. The basin population already suffers from chronic poverty. Based on a literature review, this paper suggests some key water-related and other interventions that are capable of easing the basin’s development challenges.
Book Synopsis Multiple sources of water for multiple purposes in northeast Thailand by : Penning de Vries, F.
Download or read book Multiple sources of water for multiple purposes in northeast Thailand written by Penning de Vries, F. and published by IWMI. This book was released on 2011-02-07 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many farms in tropical countries suffer from droughts in the dry season and sometimes even in the rainy season. In order to significantly increase the capacity to store water, the grassroots Farmer Wisdom movement in Northeast Thailand innovated pond construction on homesteads. This Working Paper first documents how pond water is mainly used to irrigate crops and fruit trees, and is also used for livestock or fish, and for domestic uses, even if ample piped water is available. Households were also found to harvest rainwater from roofs; take water from canals and streams; lift water manually from shallow wells and with electric pumps from deep wells; channel run-off from roads to paddy fields; use precipitation as green water on fields; and buy bottled water. Most households combine at least six of these nine water sources. The second part describes scenarios and some outcomes of a new simulation model, BoNam. This model provides guidelines for the optimal size and site of such ponds according to biophysical factors (weather, soil and crops), socioeconomic factors (prices, availability of labor and off-farm income) and household aspirations.

To help provide an understanding of the variation, this paper builds on previous work to provide a detailed typology of irrigation systems as currently used in Ghana.
Book Synopsis Water Management and Public Participation by : Alka Upadhyay
Download or read book Water Management and Public Participation written by Alka Upadhyay and published by Springer Science & Business Media. This book was released on 2012-11-11 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated Water Resources Management (IWRM) is an approach that promotes the coordinated development and management of water, land and related resources, in order to maximize economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems. Without public interest and participation, successful implementation of IWRM plans for river basin cannot be possible. Further to this, management at the watershed level to assure water supplies to support livelihood (i.e. domestic water, irrigation, industries, etc.) and sustainable groundwater development requires water augmentation through water conservation structures, and pollution control will also play a vital role. In India, because of limited period of rainfall during Monsoon (i.e. three to four months), water conservation and rainwater harvesting have been practiced since ancient days in order to meet water demands throughout the year. These structures are generally constructed and operated through the public participation. Keeping in view of the importance of public partnership, the role of public partnership in context of water-related awareness and practices has been investigated in different parts of the Yamuna River basin. The investigation evaluates the impact of various water conservation devices on livelihood; compares the performance of recently developed water conservation structures with ancient structures; examines spatial variation of water-related problems in the basin; and proposes an institutional setup for effective governance.
Book Synopsis Climate Impacts on Water Resources in India by : Ashish Pandey
Download or read book Climate Impacts on Water Resources in India written by Ashish Pandey and published by Springer Nature. This book was released on 2020-08-31 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book chiefly focuses on environmental flow, water pollution and water quality. Several chapters also cover water treatment technologies and management. In today’s context, climate change and climate variability are important issues in the water sector, which is called upon to develop adaptation strategies to cope with their negative impacts. Human health depends upon the quality of water used for drinking and irrigation purposes. These core issues are discussed and addressed in several chapters. The book explores the impact of climate change on water resources and considers various climatological scenarios. In this regard, it carries out a trend analysis and compares the performance of various Global Climate Models (GCMs). Further, it conducts a water quality analysis and water quality mapping so as to provide information on the most vulnerable areas in the context of water quality. Emerging pollutants, generated from paper mills, are identified in order to choose an appropriate treatment technology. Bioremediation techniques are included for the characterization of improved water quality parameters. The book also presents a low-cost treatment technology for fluoride removal, which can help water managers ensure potable water to stakeholders. In terms of maintaining river ecology in the downstream areas of water resources project sites, the book provides a number of case studies on assessment of environmental flows. Advanced treatment technologies that can be highly advantageous for removing water pollutants are presented. Given its scope, the book offers a valuable resource for academics, water resources practitioners, scientists, water managers, environmentalists, administrators, NGOs, researchers and students who are involved in water management with a main focus on water pollution, the environment, climate change and health.

This book was released on 2007 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discharge from the Krishna River into the ocean decreased by 75 percent from 1960-2005, and was zero during a recent multi-year drought. This paper describes the physical geography and hydrology of the Krishna Basin, including runoff production and a basic water account based on hydronomic zones. More than 50 percent of the basin’s irrigated area is groundwater irrigation, which is not currently included in inter-state allocation rules. Future water allocation will require inclusion of the interactions among all irrigated areas, including those irrigated by groundwater and surface water.
