Only six out of India’s 22 river basins are climate resilient: IIT-Guwahati Study

Only 6 river basins including Brahmaputra, Indus, Pennar were able to sustain their primary productivity by increasing water use efficiency during drought

New Delhi: Climate change remains a matter of concern globally. A new study by Indian researchers has shown that only 6 out of 22 river basins in the country have the potential to cope with the threat of climate change, particularly droughts.

This means nearly two-thirds of India’s terrestrial ecosystems are not resilient to drought. Central India has been found to be the most vulnerable to climate change. Parts of northwestern, northeastern and southern India appear to be resilient to cope with droughts while the rest of the country is non-resilient, says the study done by researchers at the Indian Institute of Technology, Guwahati.

“We evaluated the ecosystem resilience in terms of the capability of an ecosystem to maintain its productivity during hydroclimatic disturbances,” lead researcher Dr Manish Goyal said while speaking to India Science Wire.

“Only six river basins- Brahmaputra, Indus, Pennar, west flowing rivers of Kutch and Saurashtra including Luni basin, east flowing rivers between Krishna and Pennar basins and east flowing rivers between Pennar and Cauvery basin were able to sustain their primary productivity by increasing the water use efficiency under driest years,” Goyal said.

Researchers compared response of river basin systems to water stress at different levels such as river basins, land covers, and climate types. They have developed an ecosystem resilience map of India using high resolution remote sensing satellite data for 22 main river basins. The data productivity of a river basin and evapo-transpiration was obtained from NASA’s MODIS satellite and studied along with rainfall data from the India Meteorological Department.

Drastic reduction in water use efficiency under driest conditions was observed for some basins, which highlights their inability to cope with climate change. Low primary productivity can distort the balance of ecosystem and its resistance to fight drought. “The inability of ecosystems at different scales to tolerate water-limited conditions may pose a serious challenge in terms of crop production and food security,” Goyal added.

Only two types of forests – evergreen needle-leaf forest and evergreen broadleaf forest – were found to be resilient at land-cover scale. The presence of such forests in the Brahmaputra basin could be the reason for its resilience. However, forests in some parts of Western Ghats and central India were found more vulnerable to climate change. Ganga basin, the most populous and agriculturally important basin, was also found slightly non-resilient.

“It is clear that forests have higher resilience to withstand the climatic disturbances. The deforestation activities, in the name of economic development and expansion of agriculture, will result in making country more vulnerable to climate change”, researchers said.

The research team also included Ashutosh Sharma. The  study has appeared in journal Global Change Biology.

Abhishek Banerjee says will not bow to BJP after nearly 11 hours of ED questioning

After spending nearly 11 hours before the Enforcement Directorate, TMC leader Abhishek Banerjee said he would not bow to the BJP and accused the ruling party of using investigative agencies for political purposes.

Abhishek Banerjee

Trinamool Congress leader and Diamond Harbour MP Abhishek Banerjee on Tuesday said he would not bow to the BJP after spending nearly 11 hours being questioned by the Enforcement Directorate (ED) in connection with an ongoing investigation.

Speaking after the questioning, Banerjee alleged that central agencies were being used to target opposition leaders and asserted that he would continue his political fight despite what he described as sustained pressure.

The TMC leader has repeatedly maintained that investigations involving him are politically motivated, a charge he has made on several previous occasions while appearing before central agencies.

His appearance before the ED comes amid a period of heightened political activity and multiple investigations involving leaders in West Bengal. Recent days have also seen Banerjee face summons and questioning in separate matters by state investigative agencies.

After leaving the ED office, Banerjee reiterated that he would not be intimidated and said he remained committed to his political responsibilities. He also accused the BJP of attempting to weaken opposition parties through investigative action, an allegation that the BJP has rejected in the past.

The Enforcement Directorate has not publicly commented on Banerjee’s remarks. The investigation related to the questioning remains ongoing.

DMK attacks Rahul Gandhi, accuses him of weakening opposition unity

DMK has intensified its criticism of Rahul Gandhi, alleging that the Congress leader’s actions have weakened opposition unity and strained relations within the INDIA bloc.

Rahul-Gandhi

The war of words between the DMK and Congress has intensified, with the DMK launching a strong attack on Leader of Opposition Rahul Gandhi and accusing him of contributing to divisions within the opposition alliance. The criticism comes amid strained ties between the two parties following their political split in Tamil Nadu.

According to the DMK, Rahul Gandhi’s political approach has weakened unity among opposition parties. The party’s IT wing mocked the Congress leader on social media, while an editorial published in the DMK’s official mouthpiece Murasoli questioned his recent remarks on opposition solidarity.

DMK questions Rahul Gandhi’s remarks on opposition unity

In its editorial, Murasoli argued that Rahul Gandhi was speaking about opposition unity despite, according to the DMK, contributing to disagreements among alliance partners in several states. The publication cited criticism directed at Congress by various opposition parties and suggested that the party’s actions had often created tensions within the INDIA bloc.

The editorial also referred to past political disputes involving Congress and Left parties, particularly in Kerala, claiming such episodes had raised concerns among opposition allies about Congress’s approach toward its partners.

Tamil Nadu political fallout adds to tensions

The attack comes after a major political realignment in Tamil Nadu. Following the 2026 Assembly elections, Congress ended its alliance with the DMK and joined the government led by Vijay’s Tamilaga Vettri Kazhagam (TVK). The move left the DMK in the opposition and significantly altered the political equation between the two former allies.

The DMK has alleged that Congress benefited from the alliance during the election and later abandoned its partner. The party’s editorial questioned whether assurances from Congress leadership would be trusted by alliance partners after the developments in Tamil Nadu.

Congress rejects allegations

Congress has not issued a detailed official response to the editorial, but party sources have rejected the allegations. According to the party, its decisions in Tamil Nadu were made in line with the mandate delivered by voters and were not intended to undermine either the DMK or the broader opposition alliance.

The latest exchange highlights growing strains between two key opposition parties even as leaders continue to stress cooperation on national issues. Just days earlier, Rahul Gandhi had said that the DMK remained aligned with the opposition on defending the “idea of India” despite political differences.
