In which situation will population growth data be useful in disaster management?

Correct answer: तेजी से बढ़ते जोखिम क्षेत्र में भविष्य के राहत केंद्रों की योजना बनाना

The direct answer is A. Population growth data tells planners how the number of people in a place is changing. If a flood-, cyclone-, earthquake- or landslide-prone area is growing rapidly, future disasters may affect more residents and place greater demands on evacuation, shelter, food, water and medical assistance. Authorities can use population estimates to decide where relief centres should be located, how many people they may need to hold and which routes should be prepared. B is unrelated to disaster preparedness. C describes an observation that does not measure population or plan relief. D is unrelated to population estimates and emergency services. The data does not predict every disaster by itself, but it helps estimate likely human needs. Memory cue: population data answers “how many people may need help?”
