75% districts exposed to floods, 25% have early warning systems: Report

An estimated 72 per cent of districts in India are exposed to extreme flood events but only 25 per cent of them have level flood forecasting stations, or early warning systems, a new report said on Thursday.

Despite high exposure to floods, Assam, Bihar, Uttar Pradesh, Odisha, and Sikkim are the best performing states in terms of flood early warning systems (EWS), according to the report by independent policy research think tank The Council on Energy Environment and Water.

The report showed that Himachal Pradesh, currently battling massive floods, is among the states with the lowest availability of EWS.

Uttarakhand, on the other hand, is moderately exposed to extreme flood events but has a high availability of flood EWS, it said.

Delhi, in the throes of severe flooding due to a raging Yamuna, is moderately exposed to extreme floods and has a moderate level of resilience through EWS,

Approximately 66 per cent of individuals in India are exposed to extreme flood events; however, only 33 per cent of them are covered by flood EWS. Moreover, 25 per cent of the Indian population is exposed to cyclones and their impacts, but cyclone warnings are available to 100 per cent of the exposed population, the report said.

"The district-level analysis revealed that while 72 percent of districts in India are exposed to extreme flood events, merely 25 per cent of these exposed districts have level flood forecasting stations. This means that two-thirds of individuals in India are exposed to extreme flood events, and only one-third of them have flood EWS," the report said.

According to the CEEW, 12 states -- Uttar Pradesh, Himachal Pradesh, Assam, Jharkhand, Odisha, West Bengal, Andhra Pradesh, Telangana, Tamil Nadu, Karnataka, Goa, Bihar -- are highly exposed to extreme flood events. However, only three -- Uttar Pradesh, Assam and Bihar -- have a high availability of flood early warning systems.

Odisha has moderate EWS availability and the rest low availability, indicating a gap in the planning for installing flood monitoring and forecasting stations, the report said.

Sikkim, Uttarakhand, Arunachal Pradesh, Kerala, Maharashtra, Tripura, Mizoram, Nagaland, Rajasthan, Madhya Pradesh, Gujarat, Delhi, Jammu and Kashmir and Haryana are moderately exposed to extreme floods.

While Sikkim, Uttarakhand, Arunachal Pradesh, Kerala, Maharashtra, Tripura have a high availability of flood early warning systems, the rest have a moderate resilience through flood EWS.

States such as Tamil Nadu, Himachal Pradesh, Karnataka, and Telangana have the lowest availability of flood EWS.

Research shows that 97.51 million people in India are exposed to extreme flood events, and most districts are exposed to more than one extreme event, highlighting the importance of making EWS available to all in the country, especially in the states and districts most exposed to its impacts, the report said.

The recent floods in India and Cyclone Biparjoy have once again shown the importance of investing in early warning systems, said Dr Vishwas Chitale, senior programme lead, CEEW.

"The country is rapidly expanding its early warning coverage by embracing transformative technologies. However, as we witness swapping patterns in the climatic extremes in the country, where previously drought-prone areas are now facing floods, all states need to ramp up their early warning systems to safeguard lives and livelihoods," he said.

According to him, states should leverage state-of-the-art technologies to build inclusive, impact-based multi-hazard early warning systems that involve the local communities for last-mile connectivity.

"Intensifying adaptation finance for enhancing disaster preparedness is the need of the hour, he said.

Incessant, heavy rain wrought massive damage in several parts of north India over the last few days.

Due to a rare interaction of a western disturbance, monsoonal winds and a cyclonic circulation, heavy to extremely heavy rainfall in Himachal Pradesh over the weekend caused flooding and landslides in the hilly terrain.

The gushing water swept away bridges, homes and cars, and caused widespread devastation in the state.

Neighbouring Uttarakhand also saw a similar situation with water levels of several rivers crossing the danger mark.

In Delhi, the Yamuna swelled to 208.62 metres, surpassing the previous all-time record of 207.49 metres set 45 years ago. The raging river inundated nearby streets, impacted public and private infrastructure, road and rail traffic and caused immense hardships to people living in close proximity to the river.

Curbs have also been placed for the entry of vehicles into the national capital.
