Landslide Response in Chamoli: Relief, Roles and Helicopter Sorties
On 12 August the meteorological centre forecasts extremely heavy rain for 72 hours over Chamoli district. By evening, 14 villages with about 3,200 people are cut off: two stretches of the national highway are blocked by debris, a footbridge over a tributary has been washed away, and mobile towers are running on backup power. The sub-divisional magistrate reports that five of these villages, with 1,100 people, cannot be reached by road for at least four days. Relief stock is held at Gopeshwar, 54 km away, and one helicopter is available from 07:00 with a payload of 900 kg per sortie, weather permitting. There are 26 patients needing dialysis or obstetric care and 900 head of livestock. The district disaster management authority meets at 21:00, and the state emergency operations centre wants a decision before dawn.
1. Set out the priority order for the next 72 hours, with the arithmetic for food for the five cut-off villages at 600 g per person per day, allowing 200 kg per day for medicines and fodder.

Priority order:
- Evacuation of the 26 patients requiring dialysis or obstetric care - time-critical, small in number, high in consequence.
- Search and rescue where buildings are damaged or slopes are still moving.
- Food, safe water and medicines for the 1,100 people in the five cut-off villages.
- Fodder and veterinary support for 900 livestock, which is the household economy.
- Restoration of the footbridge and road connectivity.
Food arithmetic: 1,100 × 0.6 kg = 660 kg per day. Add 200 kg for medicines and fodder = 860 kg per day, which fits one 900 kg sortie.
For 72 hours: 660 × 3 = 1,980 kg food, plus 600 kg other = 2,580 kg, or three sorties at full payload.
Because the weather may close the helipad, the plan should not rely on three separate days. Fly two sorties on day one if the window allows, carrying about 1,500 kg, so that a 48-hour buffer exists. The 26 patients should be moved on the first sortie out, not the last one in.
2. Who does what? Explain the administrative roles of the district magistrate, SDM, tehsildar, gram pradhan and the cooperative institutions in this response.

The district magistrate chairs the District Disaster Management Authority and is accountable for the overall response: declaring the situation, requisitioning the helicopter through the state emergency operations centre, deploying SDRF/NDRF teams, and coordinating line departments. The DM does not personally distribute relief; the DM sets priorities and deadlines.
The SDM of the affected subdivision acts as incident commander on the ground, runs the incident response sub-centre, and reports the verified casualty and damage figures.
The tehsildar/naib tehsildar and patwari handle revenue administration: damage assessment, relief camp registers, beneficiary lists, and certification for ex gratia, without which compensation is delayed.
The gram pradhan supplies the local knowledge - which hamlet, which family, which mule track is passable - and manages the village-level camp. The pradhan should not be the sole verifier of beneficiary lists; the patwari countersigns.
Cooperative institutions - the PACS and milk federation - are useful for fodder, grain stock and cattle-shed space, and their godowns can be relief stores. Their role must be requisitioned in writing with a receipt, otherwise stock accounts and audit become disputed later.
3. The state office suggests waiting for the road to reopen instead of flying sorties. Give your decision with reasons.
Read the worked answer
I would not wait. The road is reported impassable for at least four days, which is longer than the 72-hour forecast window and longer than the food buffer in the cut-off villages is likely to last. Waiting converts a logistics problem into a distress situation: 1,100 people, 26 patients and 900 livestock cannot be supplied by foot across a washed-out footbridge at the required daily volume of 860 kg.
Decision: begin helicopter operations at first light, subject to the pilot's weather assessment; front-load two sorties on day one to create a 48-hour buffer; evacuate the 26 patients on the outbound leg; and simultaneously task PWD and PMGSY contractors to clear the two highway stretches, with a daily progress report.
The cost of a sortie is not the deciding factor when compared with the risk to patients and the likely cost of a larger emergency later. However, sorties should be logged with payload, consignee and receipt, and the decision recorded in the DDMA minutes, because audit will ask why air operations were chosen over road transport and at whose cost.
