Abstract
The Wami Rivers basin is an important area due to its diversified use which benefits a multi-diversity of stakeholders. While large scale irrigated sugar production is the main issue of concern upstream, there are other equally important socio-economic activities which include biodiversity and environmental conservation, domestic water supply, livestock water needs, and fishing. A large water supply project has just been completed downstream of the Wami River to provide water for the Chalinze township and surrounding villages. Other important undertakings include irrigated rice farming in Dakawa area, livestock keeping activities, and the establishment of the Sadani National Park (SANAPA) and the Wami-Mbiki Wildlife Management Area (WMA). The Wami River basin forms significant parts of both the Wami-Mbiki WMA and the SANAPA wildlife conservation areas. Regardless of its importance, the basin is increasingly being degraded through deforestation for agricultural expansion, timber, and more important charcoal making. The basin is also being polluted through disposal of excess molasses from the sugar industry, and use of poisonous substances and herbs in fishing. The worsening environmental condition in the basin has become a health threat to both people in the surrounding villages and wildlife. To a large extent, such changes are intensifying poverty levels among the local population. These changes are raising concerns about the long-term environmental sustainability and health implications of the current water use competition and conflicts in the basin. The purpose of this paper is to examine the main water resource use conflicts and how they affect environmental sustainability in the long-run. It also intends to establish linkages between wildlife management, pastoralism, agricultural activities and how such linkages influence poverty alleviation efforts in the basin. An attempt has been made to examine the environmental and health implications of human activities in the basin in relation to poverty indicators, people’s lifestyle, and integrated water resource use in the Wami River basin. In the process of examining linkages and sources of conflicts, key strategies to harmonize the interests of various stakeholders and ensure integrated and sustainable use of the Wami River waters will be identified. As a conclusion to paper, issues related to population pressure, pollution, wildlife, pastoralism and many others will be discussed with the view of harmonizing the needs of various stakeholders and minimizing their effect on the river ecosystem. The discussion shows how poverty levels are linked to resources over-exploitation, hence limiting sustainability in the basin. Under the current poverty levels in almost all villages surrounding the Wami River basin, there is no alternative ways or technology to replace non-sustainable resource exploitation. Many villages depend on charcoal burning and selling as a survival strategy and source of income.
