Discuss the consequences of climate change on the food security in tropical countries. (Answer in 150 words)

Tropical food systems are highly climate-sensitive because farming depends on monsoon timing, heat thresholds and ecological stability.

Consequences

• Heat stress reduces yields of rice, wheat, maize and pulses; warmer nights increase respiration losses.
• Erratic rainfall, droughts and intense floods disturb sowing, damage soil and destroy stored grain.
• Sea-level rise and salinity threaten coastal farmland, fisheries and freshwater aquifers.
• Changing pests, diseases and vector ranges raise crop losses and input costs.
• Lower yields increase prices, malnutrition, livelihood insecurity and migration, especially among smallholders and women.

Way forward

Climate-resilient seeds, micro-irrigation, diversified crops, agroforestry, early warning, crop insurance and regional grain reserves must complement mitigation and social protection.
