Andhra Pradesh: Pulichintala Dam Gate disaster shows improper maintenance and operation

In another dam related disaster in Andhra Pradesh, a flood gate of K L Rao multi-purpose irrigation project also known as Pulichintala  Dam was washed away on August 5, 2021 raising flood alarm in downstream areas along Krishna river. As per latest information the gate has been fixed and officials have started filling up the reservoir again. However, there is no official statement regarding exact causes, financial losses, damages to dam structure and downstream flood impact caused by the apparently avoidable dam disaster. The rule curve seems to be violated in operation of every dam and the gates do not seem to have been properly maintained. An independent enquiry needs to be immediately set up to find out what lessons we can learn and how we can fix accountability for the disaster.

Himalayan Disasters: Early Warning Systems must, but much more needed

Guest Article by Prof S P Sati

The suggestion of a robust early warning system always echoes as and when there is a disaster in the Himalaya. Hence, the murmuring of having a state of art early warning system after the February 7th 2021 Rishi Ganga disaster is nothing new.

Several concerned scientists of the country are considering of instituting a new centre using the state of art remote sensing techniques. The centre would be dedicated to the early warning forecasting in the Himalayan region. This is heard practically after every disaster since last two decades.

The factors that worsen the Uttarakhand Disasters

Abstract: While Uttarakhand is vulnerable to disasters, climate change is increasing these vulnerabilities. Major human interventions like hydropower projects and highways implemented without an informed or democratic decision-making process act as force multipliers during such disasters. The violations of legal and other prudent norms in their implementation further increase the damages. The absence of necessary monitoring, early warning systems and the overall disaster management system add another layer of damages during the disasters. The lack of the ability to learn lessons from disasters and lack of any accountability ensures the perpetuation of the situation.
