The correct answer is D. All of the above.
Climate change is a major threat to Karnataka’s agriculture. Extreme weather events, such as floods, droughts, and heat waves, can damage crops and livestock, and make it difficult for farmers to grow food. Changes in rainfall patterns can also lead to crop failures, as farmers may not be able to plant their crops at the right time or get enough water. Increased temperatures can also make it difficult for crops to grow, as they may not be able to tolerate the heat.
In addition, climate change is also leading to the spread of pests and diseases, which can further damage crops. As a result of these threats, climate change is having a significant impact on Karnataka’s agriculture, and is likely to continue to do so in the future.
Here are some more details about each of the options:
- Extreme weather events: Extreme weather events, such as floods, droughts, and heat waves, are becoming more common due to climate change. These events can damage crops and livestock, and make it difficult for farmers to grow food. For example, in 2019, a severe drought affected Karnataka, leading to crop failures and livestock deaths.
- Changes in rainfall patterns: Climate change is also leading to changes in rainfall patterns. These changes can make it difficult for farmers to plant their crops at the right time or get enough water. For example, in recent years, Karnataka has experienced both droughts and floods, making it difficult for farmers to plan their crops.
- Increased temperatures: Increased temperatures are also a threat to agriculture. As temperatures rise, crops may not be able to tolerate the heat, and may suffer from heat stress. In addition, increased temperatures can also lead to the spread of pests and diseases.
All of these factors are having a significant impact on Karnataka’s agriculture, and are likely to continue to do so in the future.
