Bengaluru’s water system severely affected by climate change & human interventions say IPCC report

The recent report published by Intergovernmental Panel on Climate Change (IPCC) has cautioned that the water resources near river basins of Amu Darya, Indus, Ganges and the interstate Sabarmati river basin in India could face extreme water scarcity due to the rising effects of climate change.


The report has also highlighted that the water system in Bengaluru has been changed drastically due to urban development. “Currently Bengaluru depends on long-distance water transfers that form political conflict and a dense network of private boreholes that are depleting the city’s water resources. The restoration of the existing community-managed water tanks network offers a more sustainable and socially just alternative for managing water resources”, the report added.

The city’s water system was changed at the end of the 18th century after colonial-era & the post-independence government of Karnataka took responsibility for water management. Ideas of modernist planning influenced the development of new water infrastructure and piped networks, including the first piped infrastructure, bringing water from sources 30 km away, including the Hesaraghatta and then the TG Halli reservoirs, it added.

IPCC mentioned that Climatic and non-climatic factors such as socio-economic changes led to an increase in the water stress conditions in both water supply and demand in all subregions of Asia. These changes in space and time directly or indirectly affected water use sectors and services.
