Extent of Usability of River Water
Rivers in India carry substantial volumes of water annually, but this distribution is uneven both in time and space. While some rivers flow perennially, providing water throughout the year, others are non-perennial and experience low water levels during the dry season. During the monsoon season, a significant amount of water is lost to floods, with excess water flowing into the sea. Consequently, areas experiencing floods may coexist with regions suffering from drought. This phenomenon arises from challenges in both water resource availability and management. Mitigating the issues of floods and droughts simultaneously requires strategic measures.
One potential solution is the transfer of surplus water from water-rich basins to water-deficit basins. Inter-basin water transfer schemes have been proposed to address this imbalance. However, the implementation of such schemes faces various challenges. For instance, simply digging canals may not suffice due to the uneven terrain. The north Indian rivers, which often have surplus water, may require mechanisms to lift water from the plains to the plateau areas.
To facilitate a comprehensive understanding of the issue, organizing a debate can be beneficial. Participants can discuss and analyze various aspects, including the ranking of problems associated with river water usage. These problems may include insufficient water availability, river water pollution, silt accumulation, uneven seasonal flow, interstate water disputes, and channel shrinkage due to settlement expansion towards riverbeds.
River pollution is a significant concern caused by various human activities such as industrial discharge, waste disposal, religious practices, and urban runoff. Initiatives like the Ganga Action Plan and campaigns for cleaning rivers like the Yamuna in Delhi aim to address this issue. Collecting information on such pollution control schemes and presenting them in a comprehensive write-up can help raise awareness and guide further actions towards making rivers pollution-free.
