Q1. Describe the importance and various functions of water bodies in urban areas. Explain the factors responsible for degradation and suggest measures for revitalizing urban water bodies.
- Urban water bodies provide critical ecological services: biodiversity, microclimate regulation, groundwater recharge, flood attenuation.
- They offer significant social benefits: recreation, aesthetic value, cultural identity, and community spaces.
- Degradation factors include untreated sewage, industrial effluents, solid waste dumping, and urban encroachment.
- Altered hydrology (channelization, concretization) and weak enforcement lead to severe water body decline.
Answer: Urban water bodies, including rivers, lakes, ponds, and wetlands, are vital components of urban ecosystems, offering numerous ecological, social, and economic benefits. Their importance is underscored by their role in maintaining the hydro-geological balance of a region and supporting urban resilience. The course material highlights their critical functions in enhancing the quality of urban life. Ecologically, these water bodies provide essential habitat for diverse flora and fauna, contributin...
