Context

As India awaits the arrival of the annual summer monsoon, hopes are particularly high for normal rainfall that is so vital for agriculture, the health of forests, rivers and wetlands. The India Meteorological Department has forecast normal rainfall of 96% of the long period average of 89 cm rain, with an onset date in the first week of June in Kerala. It has also signalled a significant possibility of a deficit.

Monsoon’s Importance

The monsoon bounty is crucial for the 60% of gross cropped area in farming that is rain-fed, and represents, in the assessment of the National Commission on Farmers, 45% of agricultural output.

Given the erratic patterns of rainfall witnessed over the past few decades and their possible connection to atmospheric changes caused by a variety of pollutants, the distribution of monsoon 2019 will add to the insights.

The southwest monsoon is a determinant of India’s overall prosperity, and sustained efforts to make the best use of rainfall are absolutely important for farms, cities and industry.

Areas of Concern

Decline in groundwater

Considering that there has been a 52% decline in groundwater levels based on tests conducted last year over the previous decadal average, State governments should have pursued the setting up of new recharging wells and made improvements to existing ones on a war footing.

Delay in building infrastructure

They also have lagged in building structures to harvest surface water and helping farmers raise the efficiency of irrigation.

Ineffective Support

The approach to the farming sector, however, has been influenced more by the imperatives of an election year, and the Centre’s biggest intervention was to announce a cash handout to specified categories of small farmers.

Effects of Industrial Pollution

• A normal summer monsoon over the subcontinent brings widespread prosperity, but does not guarantee a uniform spread.

• This, as scientists point out, may be due to the effect of particulates released through various industrial and agricultural processes.

• Some of these aerosols suppress the rainfall and disperse it across the land, causing long breaks in precipitation, while others absorb heat and lead to a convection phenomenon that increases rainfall in some places.

Work on Industrial Pollution

Such evidence points to the need for India to clean up its act on rising industrial emissions, and burning of fossil fuels and biomass in order to improve the stability of the monsoon.

Freshwater availability

An equally key area of concern is freshwater availability for households, which, NITI Aayog says, account for 4% of available supplies, besides 12% used by industry.

Conclusion

Urbanization trends and the severe water stress that residents experience underscore the need for mandatory rainwater harvesting policies and augmented efforts by States to preserve surface water by building new reservoirs. Yet, governments are adopting a commodity approach to the vital resource, displaying deplorable indifference to the pollution and loss of rivers, wetlands and lakes that hold precious waters. This is no way to treat a life-giving resource.
