Government readies drought plan

The drought management information system is in place and working.

The drought management information system is in place and working.

The Ministry of Agriculture through the Department of Agriculture and Cooperation has released its national drought crisis management plan. This is not taken as the indicator that drought conditions are expected to set in, but to prepare for them where they are identified. In the fifth week of the South-West monsoon, the trend continues to be that week by week, the number of districts that have recorded less rainfall than they normally receive outnumber those districts with normal rainfall. When this happens over a prolonged period, such as four to six weeks, drought-like conditions set in and the administration prepares for these conditions. [Links to the documents are at the end of this posting.]

There are a group of ‘early warning indicators’ for the kharif crop (sowing June to August) which are looked for at this time of the year. They are: (1) delay in the onset of South-West monsoon, (2) long ‘break’ activity of the monsoon, (3) insufficient rains during June and July, (4) rise in the price of fodder, (5) absence of rising trend in the water levels of the major reservoirs, (6) drying up of sources of rural drinking water, (7) declining trend in the progress of sowing over successive weeks compared to corresponding figures for ‘normal years’.

On this list, points 1 and 2 are true, 3 is true for June and July until now, 4 and 5 are true, we have insufficient information for 6 and 7 but from mid-May there have been a number of media reports on water scarcity in the districts of peninsular, central and northern India. Thus the state of the ‘early warning’ indicators taken together have triggered the issuing of the government’s drought crisis management plan.

“The identified priorities of CMP are to clarify the goals and define the roles and responsibilities of various responders (ministries / departments, organisations and individuals) involved in crisis management, and putting together a communication process for quickly notifying the public in the event of a crisis,” the ministry has explained. “The plan outlined in this document does not replace the emergency procedures or contingency action plans already drawn by different agencies, but has been developed to address crisis situations that have the potential for a much greater impact on the nation.”

The reason we have plans at the national and state level, and contingency plans for each district in the event of drought, drought-like conditions, and water scarcity is the combination of several factors:

  • Every year more than 50 million people are directly exposed to drought and its effects, with 16% of India’s total area considered prone to drought.
  • In four out of every ten years rainfall in India is erratic.
  • Drought in varying degrees affects 68% of the sown area.
  • Regions with annual rainfall of 750-1,125 millimetres account for 35% of the land area and are drought prone.
  • Most of these zones lie in the arid (19.6%), semi-arid (37%) and sub-humid (21%) regions of India.
  • Up to three-quarters of the annual average rainfall occurs over 120 days of the year. A third of the total land area receives less than 750 mm of rainfall and is chronically drought prone.

In this ‘warning phase’ – which many districts have entered – the crisis management plan calls for short-term water conservation measures by municipal and district agencies, water-budgeting by the Ministry of Water Resources (Irrigation), the Ministry of Urban Development and by the Department of Drinking Water and Sanitation. Municipal and town councils are instructed to identify alternative sources of water when the town is in a ‘warning’ period and the supply of water may be restricted to 70 litres per person per day (about half of the normal 135). Water rationing and restricted use become urgent with municipal and town councils instructed to ensure that drinking water is not used for other purposes (like washing cars, watering gardens, and so on).

State governments have in place standing instructions of designating officers responsible for meeting the needs of rural and urban citizens during drought and drought-like conditions. This document contains the list of nodal officers of the line ministries and departments, and of the Ministry of Agriculture’s drought management division, with their contact details.

Gauging four weeks of rain in the districts

We now have rain data for four complete weeks from the India Meteorological Department (IMD) and for all the districts that have reported the progress of the monsoon. The overall picture is even more serious than reported earlier because of the falling levels of water in the country’s major reservoirs. [05 to 11 June is the first week. 12 to 18 June is the second week. 19 to 25 June is the third week. 26 June to 02 July is the fourth week.]

Using the new measure of assessing the adequacy of district rainfall (and not the meteorological gradations that is the IMD standard), in the fourth week of the monsoon the number of districts that reported normal rains in that week (+5% to -5%) is 16; deficient 1 (-6% to -20%) is 31; deficient 2 (-21% and more) is 437; excess 1 (+6% to +20%) is 17; excess 2 (+21% and more) is 113; no data was reported from 25.

A third dry week of monsoon 2014

05 to 11 June is the first week. 12 to 18 June is the second week. 19 to 25 June is the third week. The bars represent the weeks and are divided by IMD's rainfall categories, with the length of each category in a bar showing the proportion of that category's number of districts. The colours used here match those used in IMD's weekly rainfall map (below) which displays the category-wise rainfall in the 36 meteorological sub-divisions (but not by district).

We now have rain data for three complete weeks from the India Meteorological Department (IMD) and for all the districts that have reported the progress of the monsoon.

The overall picture remains grim. In the third week of the monsoon the number of districts that reported normal rains in that week (-19% to +19% of the average) is only 74. No rain (-100%) was reported by 71 districts Scanty rain (-99% to -60%) was reported by 221 districts, deficient rain (-59% to -20%) was reported by 125 districts, excess rain (+20% and more) was reported by 129 districts, and there was no data from 21 districts.

IMD_districts_table_3_weeksThe Department of Agriculture and Cooperation, of the Ministry of Agriculture, has already issued its guidance to states on the contingency plans to be followed for a delayed monsoon. That is why it is important to make available the district-level normals and rainfall departures – the meteorological sub-divisions are too broad for such analysis and are irrelevant to any contingency plans and remedial work.

By end-June, when the IMD updates its outlook for the rest of monsoon 2014, we expect more detailed assessments of the districts to be publicly available – the agromet (agricultural meteorology section) already provides this to the states, with state agriculture departments given the responsibility of ensuring that the advice – which is especially important for farmers to plan the sowing of crop staples – reaches every panchayat.
