 During the fag end of 2015, Chennai experienced severe floods resulting in the death of about 500 people and economic losses of about INR 50,000 crores. The flooding stranded the city and was termed a 'man-made disaster' resulting from irresponsible water management and rapid urbanisation. The northeast monsoon of the year left most parts of South India marooned, exposing how vulnerable our cities are to such catastrophes. That's when the Office of the Principal Scientific Advisor took a major initiative to develop a real-time, integrated, urban flood forecasting system that was non-existent in our country. Soon after, a team of scientists from various institutes across the country, swung into action to develop the first-ever expert system in India to forecast floods. In a recent study, published in the journal Current Science, the researchers shed light on the development of the automated flood forecasting expert system.

Study from  Indian Institute of Technology and National Institute of Hydrology, Roorkee find the total area and number of glaciers in the Himalayas to decrease. The study shows that the glaciers are sensitive to climate change and the long term decrease in the extent of the glaciers could lead to flash floods and water shortage in the future.

Flooding in urban areas in a major threat to life and property. While there is a focus on immediate relief to the victims after the flood, long term effects of the flood need to be explored in more depth. In a recent study, an international team of scientists explores the aftermath of the floods in Chennai in 2015 with regards to the potability of groundwater. The team shows that even five months after the floods the groundwater is still unsafe for human consumption due to heavy metal and microbial contamination.

The Indian subcontinent is prone to a large number of natural disasters. The 58% of the landmass is prone to earthquakes and 12 % to floods. 68% of country’s agricultural land is prone to droughts. Apart from these, bad policy making and unplanned development has also contributed to man-made disasters in the country. On the occasion of International Day for Disaster Reduction, learn about the the measures the country has already taken and what more can be done, to reduce the devastation caused by disasters.

Each monsoon brings a fury of rains in different parts of the country killing many people and damaging properties. In spite of having disaster warnings in place, India still battles floods and the rains as many of us watch helplessly. But perhaps no more, thanks to science! Researchers have now developed a new technique to forecast extreme rainfall events by considering regional parameters that affect the quantity of precipitation. This model, which is accurate than existing models used to forecast rains, can be used for any region by including regional parameters like temperature and humidity, say the researchers.
