La lucha por el agua en Bangalore: ¿se está secando el Silicon Valley de la India? | DW Documental

Bangalore, also known as Bengaluru, has transformed into India's Silicon Valley over the last 40 years, becoming a hub for information technology. However, this uncontrolled growth, fueled by urbanization and an expanding concrete jungle, has led to a severe water scarcity. The city's groundwater resources are severely depleted, forcing residents to rely on limited and expensive water deliveries.

Bangalore's rise as an IT powerhouse, attracting companies like Texas Instruments, Wipro, and Apple, has created immense employment opportunities but also placed an unprecedented demand on water resources. The IT parks, while providing economic growth, were not planned with sustainable water management in mind, and the local authorities struggle to keep pace with the infrastructure needs.

The booming real estate sector, driven by the IT industry, has contributed to the water crisis through the illegal encroachment of public lands, particularly lakes. This 'land mafia,' often with the complicity of government officials, has led to the disappearance or contamination of 90% of Bangalore's lakes, further exacerbating the water shortage despite Supreme Court rulings to protect them.

The Bangalore Water Supply and Sewerage Board (BWSSB) faces significant challenges in delivering water to the city. Leaky and old infrastructure, with 30% of water lost to leaks, compounds the problem. Replacing these aging pipes is costly, and the city's sole reliable water source, the Cauvery River, is battling with its own drying up canals, leading to rationing and protests from farmers.

Farmers in the Cauvery River basin are severely impacted by the water diversions to Bangalore. With irregular water supply, once-fertile lands are now dry, leading to crop failures and debt. This economic hardship has driven farmers to suicide and forced many to migrate to Bangalore's slums in search of work, further straining the city's resources and highlighting social inequality.

Engineer Vishwanath, known as the 'rain man,' advocates for decentralized water management systems, including rainwater harvesting and greywater recycling. His initiatives demonstrate how individuals and communities can achieve water self-sufficiency. Local citizens are also mobilizing to restore and protect the remaining lakes, recognizing their vital role in the city's ecological balance.

Historian Marine Nendra argues that Bangalore's future lies in reconnecting with its past, when city planning prioritized the creation of lakes and green spaces for sustainable growth. The efforts to restore lakes like the Hurali Lake show that citizen action and collaboration with the government can lead to positive change. Bangalore's water crisis serves as a warning to other megacities globally, urging a re-evaluation of development models that often ignore environmental consequences.
