Climate Change on Agriculture

• Definition: Long-term changes in temperature and precipitation caused by human activity.

• Impact on Crops: Heat stress reduces yields (e.g., up to 6% reduction for wheat per degree of warming). Longer growing seasons may shift planting times, but increased greenhouse gas emissions from agriculture require intensified production.

• Extreme Weather: Sudden agricultural disruptions lead to price increases, and conditions like heat and drought cause soil erosion, affecting fertility and increasing pest issues.

• Precipitation Changes: Droughts result in water scarcity and challenges in irrigation, leading to soil degradation.

• Livestock Emissions: Livestock contribute to 15% of greenhouse gases, facing nutritional deficiencies and higher feed costs, alongside increased disease risks.

• Food Production Consequences: Less arable land and rising costs lead to higher food prices, poverty, and insecurity.

• Farmers' Challenges: Crop failures, economic instability, high adaptation costs, and health risks from stress are key issues.

• Adaptation Strategies: Farmers are employing improved irrigation, agroforestry, conservation efforts, and adjusting planting schedules to cope with climate change.

• Conclusion: Highlighting the urgent need for agricultural adaptation to climate change challenges is crucial.
