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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the management of surface water and groundwater resources. Meeting the challenges and the impact of climate change on water resources is also discussed in the book. Most chapters give insights into the interpretation of field information, development of models, the use of computational models based on analytical and numerical techniques, assessment of model performance and the use of these models for predictive purposes. It is written for the practicing professionals and students, mathematical modelers, hydrogeologists and water resources specialists.
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.

Download or read book Flood recession agriculture for food security in Northern Ghana written by Sidibe, Yoro and published by Intl Food Policy Res Inst. This book was released on 2016-02-26 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review describes a range of physical and socio-economic scientific methods and field activities that will be implemented in a proposed research project to develop a better understanding of the extent and patterns of flooding and the potential of flood-recession agriculture. These activities will allow the hydrological characteristics of the river to be matched to crop-livestock systems of flood recession agriculture that are well suited to the study communities and their organizational and institutional frameworks in order to support sustainable growth of such systems. This detailed study will provide recommendations on the technical, economic, institutional and policy measures needed to achieve sustainable intensification of flood recession agriculture in northern Ghana, while complementing efforts undertaken to promote other types of water management systems. Options for out-scaling of flood recession agriculture beyond the study area to other suitable areas will also be explored. The expectation is that the proposed project will improve food security by enhancing knowledge on effective flood recession practices, enhance rural incomes through expanded dry-season farming with new opportunities for rural employment, and improve adaptation to climate change by building more resilient farming communities. To achieve these expected outcomes, proactive policies that clearly identify flood recession agriculture as an alternative farming practice and provide institutional mandates to irrigation support services to promote it through training, demonstration, and outreach programs will be equally valuable.
Download or read book Ecophysiological Diversity of Wild Arabica Coffee Populations in Ethiopia written by Taye Kufa Obso and published by Cuvillier Verlag. This book was released on 2006 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coffea arabica, one of the economically most important crops worldwide, occurs naturally in the undergrowth of montane rainforests of Ethiopia. The study provides the first detailed ecophysiological investigations of wild coffee populations. It demonstrates the inter- and intra-regional variability in phenotypic and hydrological characteristics of wild coffee. The results reveal very different strategies of wild coffee seedlings for coping with drought stress. The ecophysiological diversity shows the importance of Ethiopian wild coffee populations as gene pools for future breeding programs, and underlines the need for an in-situ conservation strategy. The study includes recommendations for coffee forest management and the use of wild arabica coffee in Ethiopia.
Download or read book Management of Bombus Atratus Bumblebees to Pollinate Lulo Solanum Quitoense L a Native Fruit from the Andes of Colombia written by Maria Teresa Almanza Fandiño and published by Cuvillier Verlag. This book was released on 2007 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solanum quitoense (Lulo) from the northern Andes is a fruit with an attractive taste. It has a high export potential but its production is hampered by insufficient pollination. Studies on the reproductive system of Lulo revealed that, due to their poricidal anthers, the flowers need pollinators for self- and cross-pollination. Pollination by native bumblebees significantly increases fruit set and quality. Experiments show that colonies of Bombus atratus can be reared in captivity and used in Lulo fields for providing increased pollination services. Modeling based on data on colony development reveal larva/workers ratio and the supply of pollen as main parameters for improving the rearing method.

This book was released on 2004 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The study presents the analyses of field observations and simulation experiments with an event-based, two-dimensional hydrodynamic model. The model summarized the interactions between temporally dynamic rainfall, infiltration process and surface runoff in a catchment with varied soil physio-hydraulic properties, surface-roughtness, slope-lengths and vegetation structure. Both observation and simulation results indicate that the observation scale affects runoff coefficient and runoff discharge per unit area. The effect of scale is a result of spatial variability in infiltration opportunities, which vary with the slop length and distribution of saturated conductivity, leading to different trasmission losses potential during runoff routing downslope. The magnitude of the difference is influenced by surface and vegetated microtopography, which determine the flow rate"--Back cover.
