Download or read book Agricultural Water Storage in an Era of Climate Change Assessing Need and Effectiveness in Africa written by Matthew McCartney and published by IWMI. This book was released on 2013-06-06 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: By mitigating the vagaries of climate variability, agricultural water storage is widely anticipated to make a key contribution to climate change adaptation in Africa. However, if the planning of water storage is not improved, it is likely that many investments will fail to fully deliver intended benefits. This report describes the agricultural water storage continuum and some of the possible implications of climate change. A simple diagnostic tool which can be used to provide a rapid evaluation of the need and effectiveness of different water storage options, under existing and possible future climate conditions, is presented.

Download or read book The Impacts of Climate Change on Regional Water Resources and Agriculture in Africa written by Kenneth M. Strzepek and published by World Bank Publications. This book was released on 2007 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water Balance) applied to gridded data to simulate changes in soil moisture and runoff across the whole continent of Africa rather than to any particular catchment or water resource system. The model inputs were the climate variables of the 1961-90 climatology and physiological parameters (such as soil properties and land use) derived from global datasets for each of the 0.5 degree latitude/longitude cells across the continent. The primary model output comprised a time series (monthly time step) of simulated runoff for all the grid cells for each of the districts in the countries of interest. The second phase of the study extended the hydrology analyses to update the above hydroclimatic series to the year 2000 using updated input data. To ascertain the possible impacts of climate change within the districts being investigated this study used synthetic or GCM-based climate change scenarios as input to the WatBal model. The WatBal model was used to determine the impact of these different scenarios on runoff and actual evaporation and hence flow in the districts under study. The generated hydroclimatic series and scenario analyses were used as inputs into various Ricardian regressions in other analyses measuring likely impacts of climate change on the agricultural economies of Africa.

Download or read book Water Resources written by Alexander Lane and published by John Wiley & Sons. This book was released on 2017-07-18 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 7 billion people demand water from resources that the changing climate is making more and more difficult to harness. Water scarcity and shortage are increasingly common and conditions are becoming more extreme. Inadequate and inappropriate management of water is already taking its toll on the environment and on the quality of life of millions of people. Modern water professionals have a duty to develop sound water science and robust evidence to lobby and influence national and regional development policy and investment priorities. We need to be bold and brave to challenge the status quo, argue the case for change, and create a New Water Architecture. Water Resources: A New Water Architecture takes a unique approach to the challenges of water management. The stress caused by our desire to live, eat, and consume is examined in the context of Governance, the role of policy, and the commercial world. The authors share their nine-step vision for a New Water Architecture. Written by three industry practitioners, this book provides students, young professionals, policymakers, and those interested in the sustainability of our natural resources with a pragmatic and compelling perspective on how to manage the ultimate resource of our time.

Download or read book Determinants of Adoption of Rainwater Management Technologies among Farm Households in the Nile River Basin written by Gebrehaweria Gebregziabher and published by IWMI. This book was released on 2013-10-18 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is the main sector of the Ethiopian economy. Uneven distribution of rainfall, droughts and high rainfall intensities contribute to low agricultural productivity and high levels of food insecurity. High population growth, the cultivation of steep and marginal lands, poor land management practices and lack of effective rainwater management (RWM) strategies aggravate the situation. Studies show that the adoption of RWM technologies is low and is influenced by several factors. This study assesses the patterns and the factors that influence farm household adoption of RWM technologies. Unlike previous studies which typically examined a single technology rather than the interdependence between technologies, the conceptual framework of this study is based on the premise that farmers are more likely to adopt a combination of promising RWM technologies. The need to consider this interdependence is one of the many recommendations made by this study to promote the adoption of RWM technologies.

Book excerpt: The Multi-stakeholder Policy Formulation and Action Planning approach was applied in the context of a multi-city study to influence and/or change policies that govern urban agriculture practices in three African and two Asian countries. Although the approach was successful and resulted in remarkable outcomes, it showed space for improvement to facilitate its application. The study also showed that there are significant regional differences in how best to achieve policy change, which require careful attention in order to achieve the highest returns on investment in the facilitation of impact pathways.

Download or read book Land Reforms and Feminization of Agricultural Labor in Sughd Province Tajikistan written by Nozilakhon Mukhamedova and published by IWMI. This book was released on 2014-10-10 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report analyzes the influence of agrarian transformations on the feminization of agricultural production in rural Tajikistan. It explores women’s multiple labor relations for meeting basic needs of the household. The evidence shows that households have to depend on more types of agricultural work to secure day-to-day as well as long-term livelihood security. Overall, feminization appears in different types and groupings. The implication is that women in agriculture might not be adequately targeted in policies or integrated within intervention programs.

Download or read book Global Water Demand Projections Past Present and Future written by Upali A. Amarasinghe and published by IWMI. This book was released on 2014-10-10 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of global water demand projections (WDPs) show substantial over- or under-estimation. The pre-1990 WDPs, with population as the main driver of change, over-projected current water use by 20 to 130%. The post-1990 WDPs, with sophisticated modeling frameworks, show substantial underestimation under the ‘business-as-usual’ scenarios and are more downward biased under sustainable scenarios. Overall, the value of long-term country-level projections in global WDPs is inadequate for local water resource planning. To increase the accuracy and value of global WDPs, future WDPs should take into account the spatial variation and influence of rapidly changing key exogenous and endogenous drivers of water demand in different sectors across and within countries, and provide a sensitivity analysis of projections.

Download or read book Water for Food in Bangladesh Outlook to 2030 written by Amarasinghe, Upali A and published by IWMI. This book was released on 2014-10-10 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study assesses the changing consumption patterns of rice in Bangladesh and its implications on water demand by 2030. Rice dominates food and water consumption patterns in the country; it contributed to 72% of the total calorie supply from food, and 81% and 79% of the total cropped and irrigated area, respectively, in 2010. Forecasts using time series models show rice demand for food consumption, which was 172 kg/person/ year in 2008, will have a negligible increase by 2 kg/person by 2030. The demand for rice for feed will double with increasing animal products in the diet, which is only 4% of the calorie intake in 2008. Between 2000 and 2010, the total population and demand for rice have increased by 15% and 22%, and these will increase further by 22% and 25%, respectively, over the next two decades. Forecasts of rice yield, area and production show that the country can meet the increasing demand for rice and can also have substantial production surpluses. However, the rice surpluses will come at a considerable environmental cost, because the demand for groundwater consumptive water use from irrigation alone could exceed the natural recharge in many locations. Bangladesh can mitigate potential water crises by limiting rice production to meet the requirements of self-sufficiency. Increases in water productivity of both Aman (wet season) and Boro (dry season) rice production can help too. A carefully designed deficit irrigation regime for Boro rice can increase transpiration, yield, water productivity and production, and reduce the pressure on scarce groundwater resources. Simultaneously, attention must also be given to exploring the potential of recharging groundwater using the vast amount of monsoon floodwaters to alleviate the stress on groundwater resources.

Download or read book A participatory approach for hydrometeorological monitoring in the Blue Nile River Basin of Ethiopia written by Zemadim, B. and published by IWMI. This book was released on 2014-04-08 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Participatory research is increasingly recognized as being useful for conducting multiple activities in research for development projects. The co-learning environment created in participatory research helps to identify existing social and technological gaps, and develop possible solutions to improve the livelihoods of rural communities. This report describes a participatory approach used in the establishment and implementation of hydrometeorological monitoring networks in the Blue Nile River Basin of Ethiopia. The networks were established with the involvement of rural communities and other stakeholders to gain insights into the hydrological processes of the watersheds, in order to improve rainwater management strategies. Local people were involved in the day-to-day management and maintenance of the networks. The participatory approach proved beneficial for several reasons, not least, because it instilled trust and goodwill amongst the communities.

Download or read book Understanding Farmers Adaptation to Water Scarcity written by Wafa Ghazouani and published by IWMI. This book was released on 2015-02-18 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken to analyze farmers’ adaption to water scarcity in the command area of a secondary canal in the Nile Delta of Egypt. The results revealed that farmers’ responses were driven by a multiplicity of factors, beyond water scarcity or profit maximization. These additional factors include food security of the family, risk management, social capital and history of farmers, and most unexpectedly the collective dimension of crop choice. The findings of this study expose the limitations of projects, modeling exercises or policy recommendations that are too often based on the oversimplified view of profit maximization as the basis of farming system dynamics.

Download or read book Is Social Cooperation for Traditional Irrigation while Technology is for Motor Pump Irrigation written by Mengistu Dessalegn and published by IWMI. This book was released on 2015-02-18 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a case study in Ethiopia, this paper shows that while farmers understand the social nature of community-managed irrigation, they share a narrow understanding of pump irrigation with policymakers as being primarily ‘technical’. They perceive pumps as liberating them from the ‘social’ limitations of traditional communal irrigation. However, the rapid expansion of pump irrigation is leading to increasing competition and conflict over limited water resources. We analyze the wider implications for Africa of this lack of visibility of the social dimension of pump irrigation, and offer suggestions for future policy and applied research to address the problem before it becomes a widespread crisis.
