Book Synopsis Shallow groundwater in the Atankwidi Catchment of the White Volta Basin: current status and future sustainability by : Barry, Boubacar
Download or read book Shallow groundwater in the Atankwidi Catchment of the White Volta Basin: current status and future sustainability written by Barry, Boubacar and published by IWMI. This book was released on 2010 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.
Book Synopsis Smallholder shallow groundwater irrigation development in the upper east region of Ghana by :
Download or read book Smallholder shallow groundwater irrigation development in the upper east region of Ghana written by and published by IWMI. This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In sub-Saharan Africa, there is paucity of information on the potential of groundwater resources. The limited available information paints a pessimistic view about groundwater resources. Due to its perceived inadequate availability, groundwater is associated with domestic use but the potential for using it for agriculture is not well reflected in the national irrigation policies. Contrary to official pessimism, farmers do use groundwater for agriculture in many countries of sub-Saharan Africa including Ghana. This paper analyzes the current extent of use, economics, socioeconomic impacts, and constraints and opportunities of shallow groundwater irrigation based on the experiences of smallholders in the three micro-watersheds of the White Volta Basin in the Upper East Region of Ghana.
Book Synopsis Sustainable Use of Soils and Water by : Fernando António Leal Pacheco
Download or read book Sustainable Use of Soils and Water written by Fernando António Leal Pacheco and published by MDPI. This book was released on 2020-04-30 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on the sustainable use of soils and water addressed a variety of issues related to the utopian desire for environmental sustainability and the deviations from this scene observed in the real world. Competing interests for land are frequently a factor in land degradation, especially where the adopted land uses do not conform with the land capability (the natural use of soil). The concerns of researchers about these matters are presented in the articles comprising this Special Issue book. Various approaches were used to assess the (im)balance between economic profit and environmental conservation in various regions, in addition to potential routes to bring landscapes back to a sustainable status being disclosed.
Book Synopsis The Volta River Basin by : Timothy O. Williams
Download or read book The Volta River Basin written by Timothy O. Williams and published by Routledge. This book was released on 2016-09-19 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Volta River Basin (VRB) is an important transboundary basin in West Africa that covers approximately 410,000 square kilometres across six countries: Benin, Burkina Faso, Côte d’Ivoire, Ghana, Mali and Togo. Its natural resources sustain the livelihoods of its population and contribute to economic development. This book provides a comprehensive, interdisciplinary review and assessment of the issues and challenges faced. The authors provide a science-based assessment of current and future scenarios of water availability, the demands of key sectors, including agriculture and hydropower, and the environment under changing demographic, economic, social and climatic conditions. They also identify solutions and strategies that will allow available water resources to be sustainably used to improve agricultural productivity, food security and economic growth in the VRB. Overall, the work examines from a multidisciplinary and multi-stakeholder perspective the solutions and strategies to improve the use of water and other natural resources in the VRB to achieve enhanced food security, livelihoods and economic growth.
Book Synopsis The Water Resource Implications of Changing Climate in the Volta River Basin by : Matthew McCartney
Download or read book The Water Resource Implications of Changing Climate in the Volta River Basin written by Matthew McCartney and published by IWMI. This book was released on 2012 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Volta River is one of the major rivers in Africa. In this study, a dynamic regional climate model (CCLM), a hydrological model (SWAT) and a water resource model (WEAP) were used to provide an assessment of one downscaled ‘middle impact’ climate change scenario on the performance of existing and planned irrigation and hydropower schemes. The results indicate that, by the middle of the twenty-first century, altered climate is likely to undermine the technical performance of existing and planned reservoirs, which will, in turn, affect development outcomes. Future water resources development in the basin requires interventions that bolster resilience and water security. Much more systematic planning of water storage, greater cooperation between the riparian states and consideration of innovative approaches to water storage are needed.

This book was released on 2010 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Indus and Ganges River Basin, being the most populous in the world, is under extreme pressure to sustain food security. Production resources including water are being exploited to various levels from underdevelopment to heavy overexploitation. This report provides a bird’s eye view of the basin and focuses on the nexus between agricultural production and water consumption, making it possible to pinpoint the areas with high/low water productivity and identify the factors behind this, which helps to promote informed decision making in light of environmental sustainability.
Book Synopsis Evaluating the flow regulating functions of natural ecosystems in the Zambezi River Basin by : McCartney, M.
Download or read book Evaluating the flow regulating functions of natural ecosystems in the Zambezi River Basin written by McCartney, M. and published by IWMI. This book was released on 2013 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: By affecting evapotranspiration and influencing how water is routed and stored in a basin, forests, wetlands and floodplains play a crucial role in the hydrological cycle. Although they are widely attributed a major role in regulating flows (i.e., both attenuating floods and maintaining flow during dry periods), these services are rarely factored into the planning and management of water resources. One reason for the failure to include them is lack of understanding. Very often the extent to which natural regulating functions really occur is unclear. Against this background, this report describes a simple, pragmatic approach for quantifying the flow regulating functions of natural ecosystems. The method has been applied at 14 locations in the Zambezi River Basin.
Book Synopsis Glacier Systems and Seasonal Snow Cover in Six Major Asian River Basins by : Savoskul, O. S.
Download or read book Glacier Systems and Seasonal Snow Cover in Six Major Asian River Basins written by Savoskul, O. S. and published by IWMI. This book was released on 2013 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a comprehensive assessment of the water storage properties of glaciers and seasonal snow, carried out for the first time at a major river basin scale, for the Indus, Ganges, Brahmaputra, Amu Darya, Syr Darya and Mekong basins. It analyzes the changes of glaciers and snow under recent climate change, i.e., between the baseline (1961-1990) and current (2001-2010) periods. The paper also addresses climate change sensitivity of glacier systems and the changes that might be expected under a warming scenario for the end of the twenty-first century.
Book Synopsis The Impacts of Water Infrastructure and Climate Change on the Hydrology of the Upper Ganges River Basin by : Luna Bharati
Download or read book The Impacts of Water Infrastructure and Climate Change on the Hydrology of the Upper Ganges River Basin written by Luna Bharati and published by IWMI. This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study assessed the variability of flows under present and ‘naturalized’ basin conditions in the Upper Ganges Basin (UGB). Furthermore, the PRECIS regional climate model (RCM) was used to generate climate projections for the UGB, with subsequent simulations of future river flows. Results show that the annual average precipitation, actual evapotranspiration (ET) and net water yields of the whole basin were 1,192 mm, 416 mm and 615 mm, respectively. Precipitation, ET and water yields were found to be higher in the forested and mountainous upper areas of the UGB. On an annual average, present-day flows throughout UGB are about 2-8% lower than under naturalized conditions. Dry and wet season flows under climate change (CC) scenario A2 are lower than that under present climate conditions at upstream locations, but higher at downstream locations of UGB. Flows under CC scenario B2 are systematically higher and lower than that under CC scenario A2 during dry and wet seasons, respectively.
Book Synopsis Urban wastewater and agricultural reuse challenges in India by :
Download or read book Urban wastewater and agricultural reuse challenges in India written by and published by IWMI. This book was released on 2013-11-14 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 1 million hectares of urban land in India could be irrigated for crops if wastewater was made safe for use. Lack of systematic data collection by municipalities makes it difficult to accurately assess the wastewater generation or estimate the total amount of urban area under wastewater irrigation, so the potential of urban and peri-urban farming could be even greater. This study attempted to analyze the current status of wastewater generation, its uses and livelihood benefits especially in agriculture, based on national data and case studies from Ahmedabad, New Delhi, Hyderabad, Kanpur and Kolkata.
Book Synopsis Water Productivity in Context by : Barker, R.
Download or read book Water Productivity in Context written by Barker, R. and published by IWMI. This book was released on 2012 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we enter an era of increasing water scarcity, there is a growing interest to find ways to capture and put water to more productive uses. Substantial increases in the productivity of water in agriculture are needed to meet the demands for food and ensure environmental security, and to satisfy the demands for non-agricultural uses. However, increasing water productivity in rice-dominated agriculture is a function of the irrigation infrastructure, advances in rice-plant breeding, and the physical, institutional and socioeconomic environments. This paper first describes the potential ways in which increased water productivity can be achieved in the context of rice production in Asia. It then illustrates the ways in which the differences in the environmental context affect the ability to increase water productivity, the approaches used and the incentives to do so. This is explained using two ‘case studies’ reflecting the experiences of Taiwan and the Philippines over the past half-century.
Book Synopsis Revisiting dominant notions: A review of costs, performance and institutions of small reservoirs in sub-Saharan Africa. by : Venot, J.-P.
Download or read book Revisiting dominant notions: A review of costs, performance and institutions of small reservoirs in sub-Saharan Africa. written by Venot, J.-P. and published by IWMI. This book was released on 2012 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report investigates the dynamics of one of the most common agricultural water management practices of sub-Saharan Africa, i.e., small reservoirs. Small reservoirs dam permanent or temporary river flows and support multiple livelihood activities (livestock watering, crop cultivation, fisheries, small handicrafts, etc.) while providing water-related ecosystem services (soil and water conservation, flood and drought mitigation, etc.). Gathering evidence from four sub-Saharan countries, Burkina Faso, Ghana, Ethiopia and Zambia, this report calls for revisiting our understanding and assessment of the costs, performance and institutions for the management of small reservoirs. A more holistic analytical approach is the first step towards an integrative governance framework. This, in turn, holds the promise of sustainable management of small reservoirs.

Book Synopsis Low-cost options for reducing consumer health risks from farm to fork where crops are irrigated with polluted water in West Africa by : Amoah, Philip
Download or read book Low-cost options for reducing consumer health risks from farm to fork where crops are irrigated with polluted water in West Africa written by Amoah, Philip and published by IWMI. This book was released on 2011 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: To identify interventions which reduce health risks of consumers where highly polluted irrigation water is used to irrigate vegetables in West Africa, scientists worked over 5 years with farmers, market traders and street food vendors in Ghana. The most promising low-cost interventions with high adoption potential were analyzed for their ability to reduce common levels of pathogens (counts of fecal coliforms and helminth eggs). The analysis showed the combination potential of various interventions, especially on-farm and during vegetable washing in line with the World Health Organization (WHO) guidelines. The tested market-based interventions were important to prevent new or additional contamination.

Book Synopsis Irrigation-nutrition linkages: Evidence from northern Ghana by : Mekonnen, Dawit Kelemework
Download or read book Irrigation-nutrition linkages: Evidence from northern Ghana written by Mekonnen, Dawit Kelemework and published by Intl Food Policy Res Inst. This book was released on 2019-12-11 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: We analyze the linkages between irrigation and nutrition using data from irrigators and non-irrigators in Northern Ghana. The results show that (i) there is a modest difference in the overall household dietary diversity score between irrigators and non-irrigators, (ii) there are significant differences in the consumption of animal source foods between irrigators and non-irrigators, (iii) there are significant differences in the consumption of fruits and vegetables as well as sugar and honey between irrigators and non-irrigators, and (iv) the sources of food consumption differ between irrigators and non-irrigators. The analysis shows strong association between households’ nutritional status and their access to irrigation, with evidences suggesting that the irrigation-nutrition linkages play out both through the income and production pathways in Northern Ghana.
