In the past decade the Tanzanian government, with a loan from the World Bank, designed and implemented a new administrative water rights system with the aim of improving basin-level water management and cost-recovery for government water-resource management services. This paper evaluates the processes and impacts after the first years of implementing the new system in the Upper Ruaha catchment. In this area, the majority of water users are small-scale irrigators and livestock keepers who develop and manage water according to customary arrangements, without much state support. Although water resources are abundant, growing water demands intensify water scarcity during the dry season. Contrary to expectations, the new system has failed as a registration tool, a taxation tool, and a water management tool, and has also contributed to aggravating rural poverty. As a taxation tool, the system not only introduces corruption by design, but also drains government coffers because the collection costs are higher than any revenue gained. As a water management tool, the new system aggravates upstream-downstream conflicts, because the upstream water users claim that paying for water entitles them to use it as they like. However, unlike these and other counterproductive impacts of the new system, the taxation of the few private large-scale water users according to negotiated rates appeared to be feasible. The paper argues that the root of these paradoxical results lies in the dichotomy between the 'modern' large-scale rural and urban economy with its corresponding legislation and the rural spheres in which Tanzania's majority of small-scale water users live under customary water tenure. While the new water rights system fits the relatively better-off minority to some extent, it is an anomaly for Tanzania's majority of poor water users. This paper concludes by suggesting easy adaptations in the current water rights system that would accommodate both groups water users, improve cost-recovery for government services, mitigate water conflicts and alleviate rural poverty.

This report presents the findings of a study to assess changes to flows into, and downstream of, the Usangu Wetlands, located in the headwaters of the Great Ruaha River, Tanzania. Hydrological data, in conjunction with remote sensing techniques, were used to provide insights into changes that have occurred to the Eastern Wetland. Results indicate that, between 1958 and 2004, inflows to the wetland declined by about 70 percent in the dry season months (July to November) as a consequence of increased human withdrawals, primarily for irrigation.

The authors reflect on the theory and process of creating effective strategies for adaptive river basin management. We formulate our framework from observations of responses to environmental and hydrological change in the Great Ruaha River in Tanzania. We find that problems occur in the pursuit of 'integrated water resources management' (IWRM) that can be attended to by applying a focused expedient approach in three states of the water availability regime: 'critical water', 'medial water' and 'bulk water'. In particular, less reliance on broad generic 'principles' and greater reference to solutions being drawn up by local resource users in relation to identified conflicts helps guide adaptive problem solving.

In the face of growing water stress and increasing concerns over the sustainability of water use, Tanzania has, in common with many other countries in Africa, focused largely on the development of more integrated catchment-wide approaches to water management. In the Great Ruaha River Basin, considerable effort has gone into increasing water productivity and the promotion of mechanisms for more efficient allocation of water resources. Over a period of five years, the RIPARWIN project investigated water management in the basin and evaluated the effectiveness of some of the mechanisms that have been introduced. The study findings are relevant to basins in developing countries where there is competition for water and irrigation is one of the main uses.

The Usangu wetlands, containing the Ihefu swamp, are one of the most valuable inland wetlands in Tanzania. Over the last decade, outflow from the swamp has ceased for extended periods in the dry season. This has had severe consequences for downstream ecosystems, including the Ruaha National Park. Results from a simple hydrological model developed for the Ihefu swamp indicate that, between 1958 and 2004, dry season inflows declined by approximately 60% and the dry season area of the swamp decreased by approximately 40% (i.e. from 160 km2 to 93 km2). The model also shows that to maintain minimum downstream environmental flows requires a minimum inflow of 7m3s?1, which is approximately 65% greater than occurs currently. There is significant potential for improving water use efficiency. However, given the socio-economic importance of current levels of water withdrawal, this inflow may be difficult to achieve. Consequently consideration needs to be given to other options, including upstream storage and water management within the wetland itself. This paper highlights that a simple model supplying relatively low- confidence, but indicative, results can provide a useful basis for contemplating water management options.

Knowledge of wetland hydrology and quantification of water inputs and outputs are Prerequisites to understanding wetland environments and determining their vulnerability to change. To get a better understanding of the dynamics of wetland change in the Usangu Plains, a study was conducted to: a) investigate the effects of human interventions on the wetlands, and b) determine the amount of dry season inflow required to maintain environmental flows downstream of the wetlands. The study integrated hydrologic data, remote sensing and GIS techniques to study the dynamics and spatial response of the wetlands. A monthly water balance model was developed for the wetlands to determine the major components of the water budget. The results of the analyses indicate that the wetlands have changed appreciably in size over recent years and the inflow volumes have decreased with time as a result of increased human interventions. The dry season vegetated swamp cover, a major component of the swamp, decreased by 67% over the 16 years from 1984 to 2000. If this trend continues, it is possible that the wetlands will undergo a change which will be extremely difficult to reverse. Downstream of the wetlands an environmental flow of 0.5 m3/s was estimated. To maintain this outflow, the corresponding inflow volume into the wetlands was estimated to be 7m3/s. To achieve this, the available dry season water resource will have to be divided 20% for anthropogenic needs and 80% for the environment to feed the wetland. The study has demonstrated the need for integrated water resources management to balance the demands between different sectors and enable appropriate catchment interventions to ensure the sustainability of wetland resources.
