Watershed Protection Challenges in Rapidly Urbanizing Regions: The Case of Tegucigalpa, Honduras
Rapidly urbanizing regions present watershed managers with a range of challenges, especially when drinking water sources and their watersheds are located within the margins of urban and suburban expansion. These challenges can be acute in those developing countries where land-use regulations and environmental protection laws are inadequate or poorly applied, the latter often a result of the lack of defined institutional responsibilities and coordination. The Los Laureles reservoir and Guacerique watershed that supply 30 percent of Tegucigalpa's drinking water provide a powerful case study of the kinds of natural resource pressures that may lead to water quality and reliability deterioration as urban growth continues. Sedimentation, high turbidity, and high pathogen counts have accompanied decisions to locate projects such as the construction of a major ring-road/highway expansion, military bases and hospitals, and a 10,000 unit public worker housing complex in the watershed. These problems have been exacerbated by the development of private housing and poultry plants, and widespread firewood extraction from the remaining forest cover around the margins and upstream of the reservoir. For a variety of reasons, geographical and economic, watersheds like Gaucerique may frequently become neglected components of the water supply system and their protection receive much lower priority than efforts to expand and improve water supply coverage to consumers. In particular, by contributing little to revenue generation in the short term, watershed spending may be cut back from already low levels during water sector privatization as managers are forced to pay greater attention to balancing their budgets.
