The Impact of Development on Urban Watersheds in Nigeria

This paper examines the effects of urban development on urban watersheds, highlighting the interactions between land use changes and watershed health. Urban watersheds play a crucial role in maintaining the environmental health and infrastructure of metropolitan areas. However, urbanization significantly impacts these watersheds, leading to water quality degradation, increased flooding, habitat destruction, and socio-economic challenges. The study discusses the consequences of increased impervious surfaces, pollutant loads, and habitat loss on watershed functions. Strategies to mitigate these impacts, including green infrastructure, riparian buffer zones, sustainable urban planning, and community involvement, are also explored. The study underscores the need for integrated watershed management to preserve the vital ecological functions of urban watersheds and enhance the overall well-being and resilience of cities. It was concluded that urban watersheds are critical for sustaining the environmental health and infrastructure of metropolitan areas. These watersheds perform vital functions, including water purification, flood control, and providing habitats for diverse species, which are essential for maintaining ecological balance and supporting urban biodiversity. It was recommended among other that there should be the adoption of green roofs and permeable pavements to reduce surface runoff and promote groundwater recharge and there should be the development and implementation of integrated watershed management plans that consider ecological, social, and economic factors to ensure the sustainable management and rehabilitation of urban watersheds.
