Main Body
Heat waves are bouts of intense heat characterised by 4-6°C excess of temperature over average, suffered adjacently to different areas by IMD.
[Simple diagram showing heat wave patterns across regions]
Reasons:
D) Climate change induced changing climatic patterns
(Eg) changing Madden Julian Oscillation
and La Niña.
(Eg) Heat dome 2 in western Europe in 2023

Impact on food security:
dependency 2) inputs for basic food items
[Complex diagram showing impact relationships]
Land Degradation:
Reduction in natural & increased drylands & agricultural output
Health encumbered due to heat-stress, dependency 2) inputs for basic food items
Impact on food security:
Deficit of water, fertilizer productivity
Way Forward:
Implementation of Paris Agreement:
Agro-forestry systems, Stronger commitment to urban ecology, Loss & Damage precipitated in agriculture.
Thus, with global side in heatwaves, there is a need to increase disaster resilience and mitigation

- Comprehensive linkage between climate change causes and food security impacts
- Mentions international frameworks like Paris Agreement
- Suggests practical solutions through agro-forestry
- Addresses both immediate and long-term concerns
