Land Use and Natural Disasters

Natural phenomena are largely benevolent and are beneficial to society. However, at times these are of severe intensity and thus become hazardous. When societies fail to cope with hazards they turn into disasters. It is ironical that on one hand improved hazard monitoring, early warning system and disaster management practices have helped in mitigating adverse impact of hazards; on the other hand land use changes have turned hazards in to disasters. It is interesting to note that land use change...

Seismological research and geosciences

India has made some major advances in seismological research in the past few decades. However, gaps continue to remain, and populations remain vulnerable to earthquakes and tsunamis. Initiatives like microzonation, and scientific drilling may yet provide a solution to these problems.

Cities most prone to extreme rain and flood ‘study reveals’

New Delhi, May 17 (G’nY News Service): A study at the University of New South Wales, Australia have determined that cities face harsher and more concentrated rainfall as climate change not only intensifies storms, but draws them into narrower bands of more intense downpours. The findings have major implications for existing storm water infrastructure, particularly in large cities, which face higher risks of flash flooding. The study titled Reduced spatial extent of extreme storms at higher temperatures...

Surface Water Storage and Disasters

Ever since independence, dams were looked upon as the temples of modern India, our saviour against droughts, and partners in India’s development. However, ill-conceived structures devoid of environmental assessment and lack of upstream and downstream flow data have turned them into killers throughout the length and breadth of the country.
