Wetlands in the Limpopo Basin support the livelihoods of many poor people through agriculture for both food production and income. Wetlands are used to mitigate the problem of low crop yields associated with low rainfall and droughts. However, wetlands are complex and ecologically sensitive environments, which fulfill other important environmental functions, such as flood control or groundwater recharge and discharge. Consequently, altering the wetland environment through cultivation has potential impacts not just within the wetland but also in downstream areas. In a context of escalating unemployment and unreliable rainfall, it appears difficult to prevent further development of wetlands for agriculture. However it is also important to ensure that this development does not compromise environmental security. Sustainable management of wetlands cannot be achieved without active participation of all stakeholders, including local communities and environmental groups. Despite the abundant literature on sustainable use of wetlands, there are few decision-support tools designed to assist stakeholders in their choices. Different approaches exist to assess the value of natural resources such as wetlands, according to types of use (e.g. consumptive/non consumptive, productive/non productive). Nevertheless, they provide values that are difficult to compare, and that furthermore reflect a balance of human activities that is likely to change over time. The framework proposed in this paper aims at analysing the trade-offs between wetlands uses by local population and preservation of environmental services, in order to support decision-making by policy makers and wetland users. The framework is based on a combination of participatory methods, observations, surveys and simulation tools to diagnose and analyse the present uses and the ecological status of the wetland. Several multi-disciplinary models (hydrological, agronomic, economic models and GIS) will be interconnected to represent the complex relationships between ecological processes and human activities in the wetland. Simulation of various scenarios of land use and farming practices will help at assessing the trade-offs among these uses and the trade-offs between them and the provision of environmental services by wetlands

The need to achieve efficient, equitable and sustainable use of water resources to meet water demands of different sectors is pressing, particularly in areas where water resources are dwindling. Along with this is the quest for a good understanding of the value of water in its different uses. Using the Change in Net Income method, this paper presents an assessment of the value of water in irrigated paddy and hydroelectric power (HEP) generation in the Great Ruaha (GR) Catchment in Tanzania. The average values of water for irrigated paddy were estimated at $ 0.01 and 0.04 per m3 for abstracted and consumed water respectively. For HEP, the values were relatively higher ($ 0.06-0.21 per m3 for gross and consumed water respectively). Yet irrigated paddy also contributes much: it supports the livelihoods of about 30,000 agrarian families in Usangu with average annual gross income of about US $ 911.90 per annum per family and the GR paddy contributes about 14-24% to national paddy production. Understanding these benefits is key to fostering informed debate on water management and allocation, identifying the base for making ‘agreeable’ trade-offs, the potential for improvement, and creating linkages with water allocation options.

The need for achieving efficient, equitable and sustainable use of water resources to meet water demands of different sectors is pressing, particularly in areas where water resources are dwindling. Along with this is the quest for having a good understanding of the value of water in its different uses. Using a simplified model derived from the residual imputation approach (the Change in Net Income Model)we assess the value of water in irrigated paddy and hydropower generation in the Great Ruaha River Catchment (GRRC) in Tanzania. The estimated productivity of water (PW) in irrigated paddy ranges from 0.059 to 0.250 kg/m3 (for withdrawn water) and 0.126 to 0.265 kg/m3 (for consumed water). The PW in hydropower generation is estimated to range from 0.45 to 1.68 kWh/m3. In monetary terms the value of water in irrigated paddy is estimated at 15.3 Tanzanian shilling (Tsh)/m3 (for water withdrawn) and 0.19 Tsh/m3 (for water consumed). The values of water for hydropower generation are relatively higher than for irrigated paddy, ranging from 59 to 226 Tsh/m3. Yet, irrigated paddy also supports livelihoods of about 30,000 agrarian families in the GRRC, with gross revenue of about Tsh 15.9 million per annum and GRCC paddy contributes about 14– 24% of national rice production. We conclude that understanding the value of water in its alternative uses is key to fostering informed debate on water management and allocation, identifying the basis for making ‘agreeable’ trade-offs, the potential for improvement and creating linkages with water allocation options particularly in agricultural-based economies, where agriculture competes with other sectors and where water re-allocation decisions may involve large transfers of water from the sector generating the highest pro-poor returns (agriculture for this case) to the sectors generating the highest economic returns (hydropower generation and industrial uses).
