Identify the reasons behind increasing number of extreme rainfall events throughout India in recent times. Assess their socio-economic impact. (Answer in 150 words)

Open scan (p.19)

Main Body

Extreme rainfall events, caused due to monsoon supplies, have been maximum in the current and previous monsoon season, as per Indian Meteorological Department (IMD).

Reasons:

1Higher high pressure conditions, South of equator facilitate faster movement towards India in south-west main.
2Intense Somali jet and Marse high near Madagascar.
3Airsheet formation in urban areas furthering entrapment of weather phenomena.
4Extreme cold in Tibet furthering Tibetan High and intense movement of air down flow.
5Increased insolation in Western plate furthering low pressure conditions and thus, higher rainfall.
6Pocketed rainfall or abrupt 'breaks' and 'spells'. [diagram showing Socio-economic impact]

Thus, rainfall deficit coupled with intense rain spells of short duration.

7Climate change induced Madden Julian Oscillation socio-economic change:

Socio-economic Impact:

Flooding [tag] Hash floods in Rajasthan.
Infrastructure damage.
Agricultural field distortion unemployment or sag economy.

Way Forward:

Efficient watershed with robust wak

harvesting [tag] Himachal Pradesh in Haryana, Punjab

Crop insurance (M) [tag] Kusuya Funds Rate in North Bihar
Watershed development programme (UDP) [tag] Monsoons are the 'makers of economy' and climate change must be capped to enable lead development.

A handwritten diagram showing interconnected factors affecting food security. Central node: 'Impact on food security' with branches to: (1) Land Degradation - Loss of availability of land for agriculture; Reduction in natural productivity increased dry land & degraded output; (2) Health dimension - due to heat stress; (3) Dependency burden - for basic food items. Additional branches show: Deficit of water, fertilizer productivity; Falling landuse productivity in agriculture; Way Forward - Implementation of Paris Agreement, Focus on production at smaller scale with verification of food pattern beyond adopted categories. Additional context includes: Agro-todary systems, Stronger commitment to urban ecology, Loss & Damage proliferated in agriculture. Bottom section notes: Thus, with global rise in resource pressure, there is need to increase disaster resilience and mitigation.
