Cyclone Evacuation with Two Shelters and 220 Boats
A cyclone warning is issued for a coastal block in Nagapattinam district at 6 p.m. on 8 December. The storm is expected to make landfall 14 hours later with wind speeds of 110-120 km/h and a storm surge of 1.5 m. The block has 12,000 people in 18 villages. Two shelters can hold 1,200 people each; one is 4 km from the sea and the other 9 km inland. 30% of villagers are fishing families who own 220 boats; many will not leave without their boats and nets. 400 elderly people and 60 pregnant women need transport; there are 6 buses and 10 tractors available. The fishing ban is already in force, but some boats are at sea. The block development officer must decide the evacuation order, priority groups, and whether to move boats.
1. Set out the order of priority for evacuation and justify it with the constraints given.

The first fact is that the two shelters hold only 2,400 people, one-fifth of the 12,000. The block cannot simply order everyone into them. The first priority is life safety for those who cannot move themselves: the 400 elderly people and 60 pregnant women, then children and the sick, using the 6 buses and 10 tractors for the longest distances. The inland shelter should receive the most vulnerable, because it is 9 km from the sea. The second priority is villages nearest the shore and within the 1.5 m surge zone; they should move first to the nearest safe pucca buildings. The panchayat must open additional identified pucca structures - schools, marriage halls, church or temple halls - and publish the list. People should not be turned away from a full shelter. The 4 km shelter is closer but more exposed; it should be used only if it is structurally safe and not in the surge path. The order should be announced village by village, with times, so that no one waits for a late bus.
2. How should the authorities deal with the 220 boats and the boats still at sea?

The authorities should not allow people to go to the shore or into the sea to save boats once the warning is in force. Boats are replaceable; lives are not. Before the winds rise, tractors can help haul boats and nets to high ground if this can be done safely within the available hours, and boat owners should be told where to secure them. A written list of boats and owners would help later compensation claims. For the boats still at sea, the Coast Guard and fisheries department must be alerted immediately with positions and numbers; local fishing associations should help identify them. The fishing ban being in force does not mean the sea is empty. The district control room should keep a single list of missing boats so that rescue is not duplicated. After the storm, the panchayat should record losses with photographs for relief.
3. Give one likely reason the evacuation may fail and one practical way to reduce that risk.
Read the worked answer
A likely reason is that fishing families will refuse to leave without their boats and nets, or will return to check on them. The shelter capacity gap makes this worse, because people who are told there is no space may decide to stay at home. A practical response is to use trusted local messengers - the ward member, the fisherman association leader and the schoolteacher - to explain the surge risk, and to give an assurance that boats and nets will be guarded after evacuation. The panchayat can also designate a livestock and equipment assembly point on high ground. People are more likely to move if they know where their property will be and who is responsible for it. A second risk is transport shortage; pre-assigning each bus to named elderly and pregnant women, rather than letting people queue, would reduce delays.
