Structure of answer:

• • Introduction (about issue of climate change).
• • Impact of climate change on world food production.
• • Impact in different parts of the world (give some examples).
• • Way forward.
• • Conclusion.

Key points:

• • Climate change can disrupt food availability, reduce access to food, and affect food quality.
• • For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.
• • Climate change is driving an increase in the intensity and frequency of hot days and heatwaves in Australia, changing rainfall patterns, increasing the severity of droughts, and driving up the likelihood of extreme fire danger weather.
• • How to protect:
• • No-Till Farming. Avoiding tillage keeps moisture, organic matter and nutrients in the soil, making farm fields more fertile.
• • Heat-Tolerant Traits. With temperatures on the rise due to global warming, heat waves are putting our crops and food security at risk.
• • Drought-Tolerant Maize.
• • Crop Protection.

  • Nitrogen-Use Efficiency.
