Climate change is expected to affect cropping patterns in Karnataka by:

Altering rainfall patterns
Increasing temperatures
Causing extreme weather events
All of the above

The correct answer is D. Climate change is expected to affect cropping patterns in Karnataka by altering rainfall patterns, increasing temperatures, and causing extreme weather events.

  • Altering rainfall patterns: Climate change is expected to lead to more erratic rainfall patterns, with both more frequent droughts and floods. This will make it difficult for farmers to plan their crops and water management.
  • Increasing temperatures: Rising temperatures will make it harder for crops to grow, and may also lead to the spread of pests and diseases.
  • Causing extreme weather events: Climate change is expected to lead to more extreme weather events, such as heat waves, droughts, floods, and storms. These events can damage crops and infrastructure, and make it difficult for farmers to get their produce to market.

The impacts of climate change on cropping patterns are likely to be felt most acutely by small farmers, who are often more vulnerable to shocks and stresses. It is important to support these farmers to adapt to climate change, and to invest in research and development to develop new crops and farming practices that can withstand the changing climate.
