Book Description
The Zambezi Environment Outlook is the integrated assessment of the state and trends of the key environmental resources, including freshwater, land, biodiversity and forests. It covers cross-sectional elements relating human settlement, agriculture, energy, tourism, industry, climate change and variability. The report provides a current update and introduces new and emerging issues, following the widely acknowledged State of the Environment Zambezi Basin2000, which was the first environmental assessment of a single ecosystem I southern Africa

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
This review presents summary information on 45 river and great lake basins of the world, which support inland fisheries. The information presented is drawn from published information in peer-reviewed journals as well as grey literature. Each basin summary is presented in a common format, covering the description of the fishery, estimates of catch and numbers of people engaged in the fishery, important biodiversity features and threats to the fishery. An analysis of the replacement costs of inland fish of the basin is also presented. This is expressed in terms of the water, land and greenhouse gas footprint that would arise if the inland fish that are currently produced had to be replaced with other forms of food (such as aquaculture fish, livestock or field crops).
