Changing Climate Demands Stronger Water Monitoring, Early Warnings: CR Patil

New Delhi: Climate change is rapidly altering the global water cycle, making stronger monitoring systems, scientific forecasting and timely early warnings increasingly important, Union Jal Shakti Minister CR Patil said on Tuesday.

Speaking at the inaugural session of the 9th India International Water Week 2026 in New Delhi, Patil said changing climate patterns were leading to highly uneven rainfall, with some regions experiencing excessive precipitation while others face prolonged dry conditions.

“We need better science, stronger monitoring, timely early warnings and better preparedness,” Patil said, according to his remarks at the event.

The minister said rainfall was also becoming less predictable, with precipitation in some places failing to arrive when it was most needed. He emphasised that emerging water risks require countries and regions to learn from one another and strengthen cooperation.

Water security needs an integrated approach

Patil described water as a shared resource and said water security should similarly be treated as a shared responsibility. Rivers cross administrative boundaries, while groundwater resources are often relied upon by multiple communities.

He called for an integrated approach to water management that takes into account water availability, source protection, groundwater recharge, efficient use and future demand.

The theme of this year's India International Water Week is “Climate Resilient Water Management”, with discussions covering issues including river-basin management, wastewater reuse, environmental flows, monitoring and early-warning systems.

From tap connections to reliable water supply

Patil also highlighted the scale of India's water-supply expansion under the Jal Jeevan Mission. According to figures cited by the minister, around 3.24 crore rural households had tap-water connections in 2019, while the number has since risen to nearly 16 crore households.

However, he said the next challenge was to ensure that tap connections translate into regular, safe and adequate water supplies. This would require continued protection of water sources, proper operation and maintenance, and greater participation from local communities.

Why stronger early warnings matter

The need for improved monitoring comes amid growing concerns over extreme rainfall, floods, droughts and groundwater stress. The World Meteorological Organization has also called for greater investment in hydrological monitoring and data sharing, noting that climate change is intensifying water-related extremes.

India has separately been expanding its weather and climate-monitoring capabilities. The government has cited the modernisation of observational networks, Doppler weather radars, ocean observation systems, high-performance computing and digital dissemination of weather alerts as part of efforts to improve forecasting and preparedness.

Climate resilience at the centre of water planning

Patil said India's water-security agenda is linked to the country's longer-term development goals. He stressed that water management cannot focus only on increasing availability, but must also address conservation, efficient consumption, groundwater recharge and protection of water sources.

The minister's remarks come as policymakers and scientists increasingly focus on building water systems that can cope with greater climate variability. Better data, forecasting, infrastructure and community preparedness are expected to play a central role in reducing the impact of floods, droughts and other water-related emergencies.
