Main Body

Ocean pollution, Indian Ocean 0.9°C rise in temperature, climate change, shipping pollution, marine heat waves, ENSO, dipolar effect. Effect on food security of India: (1) Fisheries/Aqua production: reduced by 20% with 2°C increase (FAO) (2) India 2nd largest fisheries producer (3) Effect on Monsoon: this can hamper food grains production, disrupting monsoon cycle when 50% of agriculture is rainfed (4) Increasing Drought spasm: High pressure belt over Indian ocean leads to El-NINO situation => reduced rainfall (5) Heat waves frequency: (1900-2000) saw 27% in cases in heatwaves frequency (IMD) => crop failure (6) Pest Attacks: like locusts attack due to increased temperature and humidity (7) Post-harvest losses: due to increased temperature perishability, will decrease (already 20% losses) => NITI Aayog (8) Increased cyclones @ Amphau in Gujarat (37%): in case of cyclones in Arabian sea in last 25 years => (IMO) => destruction of crops and livelihood.

Conclusion

Now, we need to mitigate these effects and adapt to make our agriculture climate resilient. Way forward: (1) Mitigating climate change through green technology, EWSDT (2) Behavioral change: LIFE Moyt (3) Climate resilient seeds for food crops like HYV seeds (4) Diversification of food basket (eg: inclusion of Milleta) (5) Acqua-culture strategy: Hydro-phonics, acquaponics, et (6) International collaboration for technology and finance transfer (eg: GEF of UNFCCC). India still has 23 core multidimensionally poor people and 15.7% of mal-nutrition, over and above this food insecurity is lost they India wants.
