Promoting climate-resilient crops can help farmers in Tamil Nadu adapt to:

The correct answer is: d) All of the above.

Climate-resilient crops are those that can withstand the effects of climate change, such as increased salinity in coastal areas, fluctuations in rainfall patterns, and soil erosion. These crops are often drought-tolerant and can grow in saline soils. They are also often resistant to pests and diseases.

Promoting climate-resilient crops can help farmers in Tamil Nadu adapt to the effects of climate change. These crops can help farmers to reduce their risk of crop failure and increase their yields. They can also help to improve the livelihoods of farmers and reduce poverty.

Here is a brief explanation of each option:

• Increased salinity in coastal areas: Climate change is causing sea levels to rise, which is leading to increased salinity in coastal areas. This can make it difficult for crops to grow, as they need fresh water to survive. Climate-resilient crops are able to tolerate higher levels of salinity, which can help farmers to continue growing crops in coastal areas.
• Fluctuations in rainfall patterns: Climate change is also causing rainfall patterns to become more erratic. This can make it difficult for farmers to plan their planting and harvesting schedules. Climate-resilient crops are able to tolerate drought and flooding, which can help farmers to continue growing crops even when rainfall patterns are unpredictable.
• Soil erosion: Climate change is also causing soil erosion to become more severe. This can make it difficult for farmers to maintain their soil fertility. Climate-resilient crops are able to grow in poor soils, which can help farmers to continue growing crops even when soil erosion is a problem.
