Rice production is dependent on temperature, floods, droughts and precipitation which are all affected by climate change. A rise in temperature of 2-4°C can result in a 15% reduction in rice yields, and 17-40% reduction in rainfed areas. Higher temperatures also cause heat stress and sterility in rice. Floods and waterlogging from increased rainfall can submerge crops, while droughts from decreased rainfall cause moisture stress and reduce tillering, plant height and spikelet fertility. Climate change is negatively impacting rice production in developing countries and arid zones, with potential solutions including controlling deforestation and building dams.

2. z Climate Change:
• Change in weather patterns for extended period of time.
• Change in average weather conditions.
• Pakistan’s annual average temperature increasing by 0.5°C
• Major Cause: Global Warming.Pakistan’s annual average temperature
increasing by 0.5°C

4. z Climate Change And Rice:
Rice production depends on;
• Temperature
• Floods
• Droughts
• Precipitation

5. z Temperature Factor;
• 2-4°C results to 15℅ reduction in yields.
• 17-40℅ in rainfed areas
• Increased pest populations.
• Additonal Co2 can benefit crops,but nullified by rise in
temperature.

6. z
• Heat stress cause sterility.
• Above 33°C sterility increases.
• Chilling requirement not fulfilled.
• Reduction in yield.

7. z Flood Factor:
• Submergence of crops.
• Waterlogging.
• Reduction in plant growth.

8. z Drought Factor:
• Less monsoon rains cause droughts.
• Particularly sensitive to moisture stress.
• Causes reduction in tillering,plant height,spikelet fertility and
delay flowering.
• Major reduction in yield.

9. z
Precipitation Factor:
• Increased rainfall lead to flood.
• Decreased rainfall causes droughts.
• Causing massive destruction in rice yield
.

11. z
• Climate change is affecting rice negatively.
• Developing countries are most affected.
• Severe effects in Arid zones.
• Controlling deforestation and making dams as a solution.
