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.
Download or read book Surface Runoff and Infiltration Processes in the Volta Basin West Africa written by Ayodele Ebenezer Ajayi and published by Cuvillier Verlag. 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.

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.
Download or read book Sustainable Groundwater Development for Improved Livelihoods in Sub Saharan Africa written by Paul Pavelic and published by Taylor & Francis. This book was released on 2023-05-08 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive analysis of the benefits and challenges of intensifying groundwater irrigation in Sub-Saharan Africa (SSA) for improving smallholder agrarian livelihoods. Only about 3% of the groundwater resources of Sub-Saharan Africa are used for irrigated agriculture despite the subcontinent’s relative abundance of groundwater. The majority of the region’s smallholders are highly dependent on seasonal dryland cropping, making them extremely vulnerable to uncertain weather patterns and droughts. Improved irrigation capabilities through sustainable groundwater development could unleash smallholder farming and make it a major driver of economic growth, poverty reduction, climate resilience, and improved food security. So, why is groundwater so underused? Tapping into groundwater requires a major shift in farming practices and it has its own challenges and requirements – smallholder access to land and finance for irrigation infrastructure and equipment, gendered and equitable adoption options. This whole list is framed in terms of what the smallholder farmers need. Hence, this should also be put in this context, supply chains, energy access, resource availability, and institutional support. The chapters in this book present a picture that is not only heterogeneous across the region, but also hold some common denominators. They serve to enrich the discourse and help better understand the barriers along the pathways toward the sustainable and transformative adoption of groundwater irrigation. The scientific information provided herein would be of interest to researchers, practitioners, decision makers and planners with interest in the region. This book was originally published as a Special Issue of Water International journal.
Download or read book Strategies for Building Resilience against Climate and Ecosystem Changes in Sub Saharan Africa written by Osamu Saito and published by Springer. This book was released on 2017-09-19 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes studies on climate and ecosystem change adaptation and resilience in Africa (CECAR-Africa), a collaboration with the goal of creating an integrated resilience enhancement strategy as a potential model for semi-arid regions across Sub-Saharan Africa by combining climate change and ecosystem change research. The case studies were conducted at multiple scales – local, national, and regional – and incorporate the natural sciences, social sciences and engineering in a transdisciplinary manner while also integrating the needs of local communities. The book chiefly addresses three thematic areas, namely: Forecast and assessment of climate change impacts on agro-ecosystems; Risk assessment of extreme weather hazards and development of adaptive resource management methods; and Implementing capacity development programs for local leaders and practitioners. The collaborative nature of the project and the use of various quantitative and qualitative research technique s and methods – such as field surveys, questionnaires, focus group discussions, land use and cover change analysis, and climate downscaled modeling – make the book truly unique. Especially at a time when both long-term climate change and short-term extreme weather events such as droughts and floods are worsening, this book offers potential approaches to developing an integrated framework for assessing the local ability to cope with floods and droughts, and for enhancing the resilience of farming communities in developing countries, which are the most vulnerable to these changes and extreme weather events. As such, it will be of interest to a wider audience, including academics, professionals, and government officials alike.
Download or read book Empirical statistical Downscaling written by Rasmus E. Benestad and published by World Scientific. This book was released on 2008 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Empirical-statistical downscaling (ESD) is a method for estimating how local climatic variables are affected by large-scale climatic conditions. ESD has been applied to local climate/weather studies for years, but there are few ? if any ? textbooks on the subject. It is also anticipated that ESD will become more important and commonplace in the future, as anthropogenic global warming proceeds. Thus, a textbook on ESD will be important for next-generation climate scientists.
Download or read book African Handbook of Climate Change Adaptation written by Nicholas Oguge and published by Springer Nature. This book was released on 2021-05-20 with total page 2822 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book discusses current thinking and presents the main issues and challenges associated with climate change in Africa. It introduces evidences from studies and projects which show how climate change adaptation is being - and may continue to be successfully implemented in African countries. Thanks to its scope and wide range of themes surrounding climate change, the ambition is that this book will be a lead publication on the topic, which may be regularly updated and hence capture further works. Climate change is a major global challenge. However, some geographical regions are more severly affected than others. One of these regions is the African continent. Due to a combination of unfavourable socio-economic and meteorological conditions, African countries are particularly vulnerable to climate change and its impacts. The recently released IPCC special report "Global Warming of 1.5o C" outlines the fact that keeping global warming by the level of 1.5o C is possible, but also suggested that an increase by 2o C could lead to crises with crops (agriculture fed by rain could drop by 50% in some African countries by 2020) and livestock production, could damage water supplies and pose an additonal threat to coastal areas. The 5th Assessment Report produced by IPCC predicts that wheat may disappear from Africa by 2080, and that maize— a staple—will fall significantly in southern Africa. Also, arid and semi-arid lands are likely to increase by up to 8%, with severe ramifications for livelihoods, poverty eradication and meeting the SDGs. Pursuing appropriate adaptation strategies is thus vital, in order to address the current and future challenges posed by a changing climate. It is against this background that the "African Handbook of Climate Change Adaptation" is being published. It contains papers prepared by scholars, representatives from social movements, practitioners and members of governmental agencies, undertaking research and/or executing climate change projects in Africa, and working with communities across the African continent. Encompassing over 100 contribtions from across Africa, it is the most comprehensive publication on climate change adaptation in Africa ever produced.
Download or read book Hydrology and Water Resources of Africa written by M. Shahin and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa, the cradle of many old civilizations, is the second largest world continent, and the homeland of nearly one-eighth of the world population. Despite Africa’s richness in natural resources, the average income per person, after excluding a few countries, is the lowest all over the world, and the percentage of inhabitants infected with contagious diseases is the highest. Development of Africa to help accommodate the ever-increasing population and secure a reasonable living standard to all inhabitants, though an enormous challenge is extremely necessary. Water is the artery of life, without it all living creatures on earth cannot survive. As such, a thorough knowledge of the meteorological and hydrological processes influencing the yield and quality of the water resources, surface and subsurface, and their distribution and variability in time and space is unavoidable for the overall development of any part of the world. It is highly probable that the said knowledge is at present a top priority to Africa, a continent that has been for so long-and probably still-devastated by the endless ambitions of colonial powers not to forget the corruption and destruction practiced by the internal powers, at least in some countries. The present book “Hydrology and Water Resources of Africa” is written with the aim of bringing together in one volume a fair amount of knowledge any professional involved in hydrology and water resources of Africa needs to know.
Download or read book Technologies for Sustainable Development written by Jean-Claude Bolay and published by Springer Science & Business Media. This book was released on 2013-08-04 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whilst scientific research can be crucial in guiding innovation and development throughout the world, it can be too detached from real world applications, particularly in developing and emerging countries. Technologies for Sustainable Development brings together the best 20 papers from the 2012 Conference of the EPFL-UNESCO Chair in Technologies for Development with the aim to explore and discuss ways to link scientific research with development practices to assist practitioners and reply directly to social needs. In order for technologies to be adopted it is not sufficient that they are low cost and affordable but also socially, culturally and environmentally accepted by the intended users. Technologies for Sustainable Development aims to explore and answer the following three questions: • What is an appropriate technology? • How can we ensure a sustainable, integrated development? • What are the conditions for co-creation and transfer of such technologies? Focusing on the importance of improving working relationships between stakeholders; researchers and decision-makers; between scientists and industrial sectors; between academics and the population; Technologies for Sustainable Development opens a dialogue necessary to create and implement the best solutions adapted to social demands.

Download or read book Adaptation to Climate Change and Variability in Rural West Africa written by Joseph A. Yaro and published by Springer. This book was released on 2016-04-12 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents conceptual and empirical discussions of adaptation to climate change/variability in West Africa. Highlighting different countries’ experiences in adaptation by different socio-economic groups and efforts at building their adaptive capacity, it offers readers a holistic understanding of adaptation on the basis of contextual and generic sources of adaptive capacity. Focusing on adaptation to climate change/variability is critical because the developmental challenges West Africa faces are increasingly intertwined with its climate history. Today, climate change is a major developmental issue for agrarian rural communities with high percentages of the population earning a living directly or indirectly from the natural environment. This makes them highly vulnerable to climate-driven ecological change, in addition to threats in the broader political economic context. It is imperative that rural people adapt to climate change, but their ability to successfully do so may be limited by competing risks and vulnerabilities. As such, elucidating those vulnerabilities and sources of strength with regard to the adaptive capacities needed to support successful adaptation and avoid maladaptation is critical for future policy formulation. Though the empirical discussion is geographically based on West Africa, its applicability in terms of the processes, structures, needs, strategies, and recommendations for policy transcends the region and provides useful lessons for understanding adaptation broadly in the developing world.
