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.

Download or read book Rural Water Systems for Multiple Uses and Livelihood Security written by M. Dinesh Kumar and published by Elsevier. This book was released on 2016-05-03 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rural Water Systems for Multiple Uses and Livelihood Security covers the technological, institutional, and policy choices for building rural water supply systems that are sustainable from physical, economic, and ecological points-of-view in developing countries. While there is abundant theoretical discourse on designing village water supply schemes as multiple use systems, there is too little understanding of the type of water needs in rural households, how they vary across socio-economic and climatic settings, the extent to which these needs are met by the existing single use water supply schemes, and what mechanisms exist to take care of unmet demands. The case studies presented in the book from different agro ecological regions quantify these benefits under different agro ecological settings, also examining the economic and environmental trade-offs in maximizing benefits. This book demonstrates how various physical and socio-economic processes alter the hydrology of tanks in rural settings, thereby affecting their performance, also including quantitative criteria that can be used to select tanks suitable for rehabilitation. - Covers interdisciplinary topics deftly interwoven in the rural context of varying geo-climatic and socioeconomic situations of people in developing areas - Presents methodologies for quantifying the multiple water use benefits from wetlands and case studies from different agro ecologies using these methodologies to help frame appropriate policies - Provides analysis of the climatic and socioeconomic factors responsible for changes in hydrology of multiple use wetlands in order to help target multiple use water bodies for rehabilitation - Includes implementable models for converting single use water supply systems into multiple use systems

Download or read book Water Supply for Counterinsurgency Operations in Northeast Thailand written by David B. Doan and published by . This book was released on 1968 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The status of water-resources investigations in Northeast Thailand is examined with particular reference to problems of civil and military water supply so as to suggest ways and means of improving existing water supply and forestalling potential water shortages in counterinsurgency operations. With 65,000 square miles and a population of roughly 10 million, NE Thailand amounts to about one-third of the entire country. Potable water is in short supply in many areas, and water distribution systems are very rare. The problem of developing more water for the civilian population is joined with the one of ensuring that sufficient water is available to counterinsurgency forces if field operations were to be undertaken. The situation is approached two ways: One aims at examination of the occurrence of water resources based on evaluation of the results of research in progress by a number of agencies. The second approach involves the preparation of scenarios to illustrate the nature of real planning problems and constraints as they might arise through three possible successive stages in insurgency in NE Thailand. Potential responsive counterinsurgency activity is suggested, including deployments of the Royal Thai Army, to set forth the problems of operations and logistics. The Royal Thai Army, moreover, represents a significant source of potential manpower for carrying out an experimental civic-action program of village-level assistance in exploitation of shallow ground-water resources.

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.

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.

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.
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.
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.

Download or read book Multi Stakeholder Platforms for Integrated Water Management written by Dr Jeroen Warner and published by Ashgate Publishing, Ltd.. This book was released on 2012-11-28 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: As they provide a negotiating space for a diversity of interests, Multi-Stakeholder Platforms (MSPs) are an increasingly popular mode of involving civil society in resource management decisions. This book focuses on water management to take a positive, if critical, look at this phenomenon. Illustrated by a wide geographical range of case studies from both developed and developing worlds, it recognizes that MSPs will neither automatically break down divides nor bring actors to the table on an equal footing, and argues that MSPs may in some cases do more harm than good. The volume then examines how MSPs can make a difference and how they might successfully co-opt the public, private and civil-society sectors. The book highlights the particular difficulties of MSPs when dealing with integrated water management programmes, explaining how MSPs are most successful at a less complex and more local level. It finally questions whether MSPs are – or can be – sustainable, and puts forward suggestions for improving their durability.
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.
