By affecting transpiration and evaporation and influencing how water is routed and stored in a basin, forests, wetlands and floodplains play a crucial role in the hydrological cycle. Although they are widely attributed a major role in regulating flows (i.e. both attenuating floods and maintaining flow during dry periods) these services are seldom, if ever, explicitly factored into the planning and management of water resources. One reason for the failure to include them is lack of understanding of the hydrological functions occurring, their dynamic nature, and the interaction of those functions with the catchments in which the ecosystems are located. Very often it is unclear exactly which functions are performed and how those functions change over time (i.e. between seasons and between years). Furthermore, both the lack of quantitative information and a recognized method to incorporate them into decision-making processes, make it very difficult to integrate natural hydrological functions into the planning and management of water resources. This report describes a pragmatic approach for quantifying the flow regulating functions of floodplains, headwater wetlands and forests in the Zambezi Basin. The method utilizes observed stream flow records and flow duration curves to derive a simulated time series of flow in the absence of the ecosystem. This can then be compared with an observed time series to evaluate the impact of the ecosystem on the flow regime. The method, which is easy to utilize and could easily be incorporated into a decision support system for the synchronization of dam operation, has been applied and results obtained for 16 locations in the basin. Results indicate that the different ecosystems affect flows in different and complex ways. Broadly: i) floodplains decrease flood flows and increase low flows; ii) headwater wetlands increase flood flows and decrease low flows; iii) miombo forest, when covering more than 70% of the catchment, decreases flood flows and decreases low flows. However, in all cases there are examples which produce contrary results and simple relationships between the extent of an ecosystem type within a catchment and the impact on the flow regime were not found.

Water infrastructure is a cornerstone of economic development. In the Zambezi River Basin huge investments have been made in dams for hydropower, irrigation, water supply and flood control. Ecosystem functions are central to outcomes from dams. Not only does the performance of dams depend on ecosystem functions but dams also modify them (e.g. by changing natural flow regimes). It is by changing ecosystem functions (and hence ecosystem services) that dams often have their greatest impact on the livelihoods of poor people. However, investment decisions and, subsequently the management of dams, rarely consider ecosystem functions. Trade-offs and synergies between dams and ecosystem functions often go unrecognized and, as a result, the benefits accruing from dams are typically sub-optimal. One reason for the failure to consider ecosystem functions is lack of understanding of them and how they translate into services for people. It is not clear which ecosystems perform which functions or how they will be affected by a dam. For example, whilst it is widely understood that in relation to hydrology, different ecosystems provide different regulating functions, there is little quantitative information on the extent to which they do this or the dynamic nature of such functions. If ecosystem functions, and specifically flow regulating functions, are to be considered in dam planning and management more information and a method to incorporate them into decision-making processes is required. Based on a literature review this report summarizes i) evidence of the flow regulating functions of the major ecosystems in the Zambezi basin and ii) methods for evaluating ecosystem flow regulating functions. Finally, it proposes an approach for developing a method that could contribute to a decision support system for the synchronization of dam operation in the basin.

The Zambezi River Basin (ZRB) is one of the most diverse and valuable natural resources in Africa. Its waters are critical to sustainable economic growth and poverty reduction in the region. In addition to meeting the basic needs of some 30 million people and sustaining a rich and diverse natural environment, the river plays a central role in the economies of the eight riparian countries—Angola, Botswana, Malawi, Mozambique, Namibia, Tanzania, Zambia, and Zimbabwe. It provides important environmental goods and services to the region and is essential to regional food security and hydropower production. Because the Zambezi River Basin is characterized by extreme climatic variability, the River and its tributaries are subject to a cycle of floods and droughts that have devastating effects on the people and economies of the region, especially the poorest members of the population.

Wetlands and forests have strong effects on hydrological processes by changing the rate of evaporation, transpiration, and flow routing in a basin, which affects basin water management such as dam operations. This study aims to assess the flow regulating functions of wetlands and forests using a flow duration curve (FDC) approach. We firstly identify wetlands and forests which are gauged both upstream and downstream. Reference conditions were then established using nearby sub-watersheds that contain few/no wetlands/forests. By transferring reference flows to the target sites and comparing the FDCs for with and without wetland/forest conditions we then assess the hydrological impacts on flood attenuation and base flow maintenance. Results of a floodplain wetland suggest that it decrease flood flows and increase low flows. The extent of this function could be quantified which gives useful indications for water resources planning and management.
