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
The Ecosystem Approach, defined as a strategy for the management of land, water and living resources that promotes conservation and sustainable use in an equitable way, was adopted at the Second Conference of the Parties of the CBD as the primary framework for action under the Convention. It puts people and their nature resource use practices squarely at the centre of the decision-making framework. The case studies presented here were discussed at three workshops held in Southern Africa, South America and Southeast Asia. They provide practical examples of the Ecosystem Approach as well as a number of recommendations for action that are widely relevant to Parties and other bodies.

Book Description
In Africa, most major rivers, freshwater lakes, and aquifers are shared by two or more countries. These nations are becoming increasingly vulnerable to conflict, and their vulnerabilities are made more acute by climatic variations in precipitation, increasing urbanization, industrialization and environmental degradation. The concept of resilience and vulnerability as it relates to water resources is tackled in this report within the framework of sustainability and relates to the ability of the human and bio-physical systems to adapt to change.

Book Description
The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.
