Introduction
Land reclamation involves transforming underwater areas into usable land for agricultural, industrial, or residential purposes. While this process can facilitate urban development, it has significant environmental consequences.
1. Loss of Biodiversity
Reclaiming water bodies leads to the destruction of habitats that support diverse aquatic and semi-aquatic species. This habitat loss can displace wildlife, disrupting local ecosystems and food chains. For instance, the reclamation around Dal Lake in Srinagar has affected the habitat of various species, resulting in reduced biodiversity.
2. Water Quality Degradation
Reclaimed water bodies are often subjected to urban runoff, sewage discharge, and other pollutants, which deteriorate water quality. This pollution can harm aquatic life and pose health risks to nearby human populations. The Cooum River in Chennai and the Sabarmati River in Ahmedabad exemplify this issue, where industrial and domestic waste has severely impacted water quality.
3. Increased Flood Risk
Water bodies play a crucial role in absorbing excess rainwater and mitigating flood risks. Their reclamation can disrupt this natural function, increasing vulnerability to flooding, as witnessed in cities like Mumbai and Bangkok, where urbanization has led to heightened flood incidents.
4. Climate Change Contribution
The destruction of water bodies reduces the carbon sequestration capacity of ecosystems. Water bodies store significant amounts of carbon, and their reclamation can release this carbon into the atmosphere, exacerbating climate change. This phenomenon has been linked to biodiversity loss, including declines in amphibian populations in tropical regions.
5. Environmental Hazards
Neglecting the natural context in water reclamation projects can lead to environmental hazards, such as increased seismic activity in coastal areas due to altered land use patterns.
Conclusion
The reclamation of water bodies for urban development carries profound environmental implications, including biodiversity loss, water quality degradation, increased flood risks, and contributions to climate change. Addressing these issues is crucial for sustainable urban planning and environmental conservation.

Model Answer
Introduction
Urban flooding in Indian cities, particularly in smart cities like Hyderabad and Pune, has become increasingly frequent due to various factors. The major cause is unplanned urbanization, which disrupts natural drainage systems and exacerbates flooding risks. Notable incidents include the 2021 Maharashtra floods and the 2022 Assam floods, which highlight the urgent need for effective flood management strategies.
Causes of Urban Flooding
Lasting Remedial Measures
Conclusion
Addressing urban flooding in cities like Hyderabad and Pune requires a comprehensive approach that includes infrastructure improvements, regulatory measures, public education, and early warning systems. By implementing these strategies, the risks associated with urban flooding can be significantly mitigated.
