We lack not at all for experience with drought, yet have not grown used to treating water with the greatest of care. Drought does not strike in the manner a hailstorm does, yet our administrations seem unable to read the signals. Citizens and panchayats alike can contribute to our managing droughts better, provided all are willing to change both perception and behaviour.
It is because drought is such a forbidding condition for any state to fall into that it becomes at once threatening and emotive. Its every symptom becomes a new trial for a drought-afflicted population and simultaneously a likely indictment of the administration, whether local or regional. Food and crop, water and health, wages and relief: this is the short list for which action is demanded by a population concerned for those in the drought-affected districts and blocks.
The administration is bound to answer, as it is likewise bound to plan, prepare, anticipate and act. But where the interrogation of a government for its tardiness in providing immediate relief comes quickly, a consideration of the many factors that contribute to the set of conditions we call drought is done rarely, and scarcely at all when there is no drought. It is the gap between these two activities that has characterised most public criticism of the role of administration today when there is drought.
For farmers and district or block-level administrators alike, drought is a normal and recurrent feature of climate in the dryland regions of India. It occurs in nearly all climatic zones – our long recording history of droughts and floods in particular show that whereas in eastern India (West Bengal, Odisha and Bihar) a drought occurs once in every five years, in Gujarat, East Rajasthan and western Uttar Pradesh the frequency is once in three years. Although the characteristics of what we call drought varies significantly from one meteorological sub-division to another, and indeed from one agro-ecological zone to another, the drought condition arises from a deficiency in precipitation that persists long enough to produce a serious hydrological imbalance.
Drought is a complex phenomenon. There is first a need to distinguish between meteorological and agricultural droughts. A meteorological drought is a period of prolonged dry weather conditions due to below normal rainfall. An agricultural drought refers to the impact caused by precipitation shortages, temperature anomalies that lead to increased evapotranspiration by crops and vegetation, and consequently to a shortage of the water content in the soil, all being factors that adversely affect crop production and soil moisture. The National Commission on Agriculture has defined an agricultural drought differently for the kharif (monsoon cropping season, July to October) and rabi (winter cropping season, October to March).
What the country has witnessed during March and April is an agricultural drought, brought about by the high temperatures which raised mean and maximum temperatures into the heat-wave band. This we have witnessed in Odisha, Telengana, Vidarbha, Marathwada, north interior Karnataka, Rayalaseema, coastal Andhra Pradesh, Tamil Nadu, eastern Madhya Pradesh and Chhattisgarh, Jharkhand and West Bengal.
