This book was released on 2021-01-11 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an analysis of the ecological conditions and ecosystem goods and services of the Zambezi River Basin (ZRB), the fourth largest river in Africa. Various environmental and anthropogenic factors; inclusive of climate, environmental flows, hydrology, morphology, pollution and land use changes among others and their interactions are considered as drivers of the river ecosystems. The impacts of these drivers on aquatic biota, river ecological integrity, and the livelihoods of surrounding communities are analysed within the socio-economic-policy context. The book goes beyond the usual inventories and basic research by using the comparative research method (CRM) in a trans-disciplinary manner. This CRM analytical approach in this book seeks to interrogate the differences or similarities in socio-economic systems, livelihoods, ecological systems, ecosystem goods and services, their usage and management under the seemingly different cultural, socio-economic conditions expected across boarders that are within the ZRB. The multidisciplinary approach also connects the typical ecological research with social dimensions in a holistic manner. The book therefore, provides empirical and research based evidence to support strategic planning and policy development in the wake of ecological changes that nations and indeed regions such as the ZRB are grappling with while seeking to sustainably manage precious river systems.

Download or read book The Zambezi River Basin written by Jonathan Lautze and published by Routledge. This book was released on 2017-07-28 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Zambezi river is the fourth longest in Africa, crossing or bordering Zambia, Angola, Namibia, Botswana, Zimbabwe and Mozambique. The river basin is widely recognised as one of the most important basins in southern Africa and is the focus of contested development, including water for hydropower and for agriculture and the environment. This book provides a thorough review of water and sustainable development in the Zambezi, in order to identify critical issues and propose constructive ways forward. The book first reviews the availability and use of water resources in the basin, outlines the basin’s economic potential and highlights key concerns related to climate vulnerability and risk. Focus is then devoted to hydropower and the water-energy-food (WEF) nexus, sustainable agricultural water management, and threats and opportunities related to provision of ecosystem services. The impact of urbanisation and water quality is also examined, as well as ways to enhance transboundary water cooperation. Last, the book assesses the level of water security in the basin, and provides suggestions for achieving Sustainable Development Goal (SDG) 6. Throughout, emphasis is placed on entry points for basin-level management to foster improved paths forward.

Download or read book From climate risk to resilience Unpacking the economic impacts of climate change in Mozambique written by Detelinova, Iva and published by Intl Food Policy Res Inst. This book was released on 2023-11-13 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mozambique is already vulnerable to extreme weather events and climate change is projected to exacerbate their frequency and intensity. The occurrence of cyclones and flooding has increased in recent years and the trend is expected to continue. The country’s coast—where 60 percent of the population, the three biggest cities, and critical infrastructure are situated—is most exposed to climate change-related risks, including damage from cyclones and projected sea level rise. Densely populated and low-lying regions, such as Zambezia, Nampula, Sofala, and Maputo Provinces, are particularly exposed to risks from flooding. More broadly, climate change is projected to increase average temperatures across the country and to result in higher variability in precipitation, especially in the south. The most critical economic sectors vulnerable to climate change in Mozambique are agriculture, transport, and potentially energy. In agriculture, maize is likely to be the most affected key crop. This can pose risks to food security (alongside expected higher food inflation because of climate change), given maize’s widespread cultivation and role in nutrition. The impact on other crops is likely to be more limited, and to a large extent driven by damages from increased frequency of extreme weather events. This could exacerbate challenges in the sector, which is already constrained by low productivity and limited arable areas. That said, climate change could create some opportunities; for example, rice yields are projected to improve. Most studies project agricultural production in the central region to be most adversely affected by climate change, albeit the impact varies by crop and within regions. Mozambique’s transport infrastructure is highly vulnerable to climate change due to the projected increase in flooding, the low proportion of paved roads, their limited interconnectivity, and the vulnerability of ports to cyclones and storm surges. Damages to Mozambique’s transport sector are likely to have knock-on effects to other sectors and can have significant regional implications, as the country serves as a conduit for landlocked neighboring countries. Infrastructure damages, alongside the projected coastal erosion, may severely affect the tourism sector. Furthermore, Mozambique’s high dependence on hydropower exposes it to losses from rainfall variability, which is expected to increase. The country’s largest hydropower plant is located downstream on the Zambezi River, which various studies project to dry up due to climate change. Increased water use in upstream countries (such as because of greater irrigation needs and in response to growing populations) could also pose risks to Mozambique’s hydropower sector.
Download or read book From climate risk to resilience Unpacking the economic impacts of climate change in Zambia written by Detelinova, Iva and published by Intl Food Policy Res Inst. This book was released on 2023-11-14 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is projected to cause an increase in average temperatures in Zambia and a decline in rainfall, particularly in the southern and western regions. The country experiences high rainfall variability, which climate change is expected to exacerbate, resulting in likely higher frequency and intensity of already reoccurring extreme weather events, such as droughts and floods. The combined effect of the temperature and precipitation projections is anticipated to cause a decrease in water availability at national level and to adversely affect the Zambezi, Kafue, and Luangwa River Basins. Overall, these trends will exacerbate existing vulnerabilities in southwestern Zambia, as the region is already prone to droughts (as well as floods in some parts). On the other hand, the northern parts of the country are projected to experience a slight increase in rainfall and to be overall relatively positively affected by climate change. The key sectors most likely to be significantly affected by climate change in Zambia include agriculture, road infrastructure, and energy. In agriculture, the key risk stemming from climate change is the projected lower maize yields, as this is the country’s staple crop. Other crops are also expected to be adversely affected by higher temperatures, reduced rainfall, and increased occurrence of extreme events, particularly in southern and western Zambia. That said, changing climate conditions could create new agricultural opportunities in the north. Climate change is projected to negatively affect the livestock subsector, which will increase food security risks, particularly for subsistence farmers. In road infrastructure, the projected higher occurrence of flooding, especially in Lusaka Province, could have a knock-on effect for the rest of the economy, particularly if it damages key international corridors passing through this region and/or affects domestic supply chains. Zambia is significantly reliant on hydropower and is already experiencing severe power cuts due to drought. The risks in the sector are exacerbated by the location of key hydropower plants in the southern parts of the country and the projected drying up of main river basins. The electricity shortages have spillover effects on the rest of the economy, including the copper industry, Zambia’s key export. This has international implications, as Zambia is a top copper producer worldwide, and demand for copper is expected to increase significantly due to its crucial role in various green technologies. Thus, absent adaptation measures, the adverse impact of climate change in Zambia could affect global mitigation efforts and strategies.
Download or read book Climate Change and Water Resources in Africa written by Salif Diop and published by Springer Nature. This book was released on 2021-02-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this book is on the key water-related vulnerabilities to climate change in Africa, particularly in its most vulnerable areas, exploring potential management responses to such vulnerabilities. The African countries are particularly exposed and vulnerable to the negative impacts of climate change, with important impacts on water resources and hydrological systems, water availability, water resource management and sea level variations. Already, under various anthropogenic pressures, the status of water resources in Africa has been changing over the past decades, with decreasing water quality, falling groundwater levels, and variability in rainfall, both in terms of timing and intensity. Climate change will further accelerate the rate of change, affecting the ability of people and societies to respond in a timely manner. It is clear that there is no quick fix to the pressures imposed on water resources by climate change. Increasing the resilience of ecosystems and communities to extreme events such as flooding and drought, and integrating climate change risks and opportunities into development decision-making is indeed a key challenge, as much a technical climate-change one, as a political and developmental challenge. The book, in this regard, intends to contribute to the debate around climate change in relation to water resources management in Africa, and in particular inform policy decisions and actions that will improve governments’ and communities’ ability to manage the challenges of climate change and variability in relation to the aquatic ecosystems that they depend on. The knowledge collected in this book will benefit policy makers, researchers, as well as other stakeholders.

Download or read book Establishing the Environmental Flow Regime for the Middle Zambezi River written by Elenestina Mwelwa-Mutekenya and published by CRC Press. This book was released on 2021-07-28 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Middle Zambezi, host to a rich biodiversity, is located in the central part of the Zambezi River Basin which covers eight Southern African Countries. The area is located downstream of three hydropower schemes. In the last decades, the floodplain riparian tree, the Faidherbia albida, vital for the local wild life, has shown a worrying decrease in its regeneration rates. This thesis explores establishing the environmental flow regime for the Middle Zambezi reach in order to minimise the impact of the upstream hydropower schemes on the river environment, using the Faidherbia albida tree as a biological indicator. The research identified that the current dam operations have completely altered the natural hydrological rhythm from pre-Kariba dam dry season flows of 100-200 m3/s increasing to 1,000-1,500 m3/s. The sudden closure of the dam floodgates can be linked to the observed river channel-widening phenomenon. In addition, the Faidherbia albida tree now experiences longer flood residence over the floodplain, making it inaccessible to animals to allow for regeneration. In order to save the F. albida tree, a two-pronged environmental flow regime is proposed of releasing a moderate flood of 5,800 m3/s once in 5 years, for 5 to 6 weeks in the months of February to March, and phasing the spillway gates closure over a period of 3 to 4 weeks to keep the floodplain wet enough until the months of May and June. Phasing of the spillway gate closure would also mitigate the excessive bank erosion.

Download or read book Climate Change and Africa written by Pak Sum Low and published by Cambridge University Press. This book was released on 2006-11-02 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the twenty-first century, no environmental issue is of such truly global magnitude as the issue of climate change. The poorer, developing countries are the least equipped to adapt to the potential effects of climate change, although most of them have played an insignificant role in causing it. African countries are amongst the poorest of the developing countries. This book presents the issues of most relevance to Africa, such as past and present climate, desertification, biomass burning and its implications for atmospheric chemistry and climate, energy generation, sea-level rise, ENSO-induced drought and flood, adaptation, disaster risk reduction, the UNFCCC and Kyoto Protocol (especially the Clean Development Mechanism), capacity-building, and sustainable development. It provides a comprehensive and up-to-date review of these and many other issues, with chapters by the leading experts from a range of disciplines. Climate Change and Africa will prove to be an invaluable reference for all researchers and policy makers with an interest in climate change and Africa.
