DRP 240723: Urgently need parameters that will truly reflect rainfall pattern

(Feature Image: – IMD’s District Wise Cumulative Rainfall Map for 01 June to 23 July 2023)

India received 389.2 mm rainfall till 0830 hrs on July 23, 2023 in SW monsoon. This being 5% above the normal rainfall till this date of 370.9 mm, India Meteorological Department and with it, the whole nation calls it Normal Monsoon. But anyone who is familiar with the rainfall pattern across India will not call it Normal.

We must urgently develop new parameters for describing the monsoon that also take into account spatial (across states, districts, Tehsils, blocks) and temporal variability. These parameters should take into account the departure from normal for each unit of space for each day and combine such departures to arrive at a figure that will better describe the monsoon for each unit of space. It can also take into consideration the high intensity rainfall events as also the longer dryer patches. This will help us understand not only the nature of monsoon rainfall, but also alert the farmers and everyone else but also help us understand how this pattern is changing over the years. This should not be so difficult for IMD to initiate and accomplish quickly. When aggregated at river basin level, this will also help us understand the actual rainfall pattern in each river basin but also how it is changing. Is this too much to ask?

DRP 170723: Man-Made Reasons That Make Flood A Disaster

Over the past 10 days, several Himalayan and North Indian states including national capital Delhi have been battling severe flood disaster which has already taken a heavy toll of human lives apart from displacing people in large numbers and causing massive scale and still unfolding destruction to public-private infrastructure which is still unfolding.

While at macro level the impact of climate change induced excessive and abnormal rainfall patterns is seen as a major culprit but the micro level analysis reveals the deep connection of human activities behind the devastation on ground.

For example, in Himachal and Uttarakhand it is increasingly becoming clear that the large-scale construction and widening of improperly designed and poorly executed highways projects have started proving a double whammy for the fragile hills and river systems.
