Strategies to build a climate-resilient food system in Sikkim include:

The correct answer is: d) All of the above

Drought-resistant crop varieties are crops that can withstand periods of drought without suffering significant yield losses. These crops are often grown in areas that are prone to drought, such as Sikkim. Water conservation and irrigation are important strategies for building a climate-resilient food system in Sikkim. Water conservation can be achieved through a variety of methods, such as rainwater harvesting, drip irrigation, and mulching. Irrigation can be used to supplement rainfall and ensure that crops have enough water to grow. Agroforestry practices are a type of land management that combines trees and crops. Agroforestry can help to improve soil fertility, reduce soil erosion, and provide a source of food and income for farmers.

Here are some additional details about each of the options:

• Drought-resistant crop varieties are crops that can withstand periods of drought without suffering significant yield losses. These crops are often grown in areas that are prone to drought, such as Sikkim. Some examples of drought-resistant crops include millet, sorghum, and chickpeas.
• Water conservation and irrigation are important strategies for building a climate-resilient food system in Sikkim. Water conservation can be achieved through a variety of methods, such as rainwater harvesting, drip irrigation, and mulching. Irrigation can be used to supplement rainfall and ensure that crops have enough water to grow.
• Agroforestry practices are a type of land management that combines trees and crops. Agroforestry can help to improve soil fertility, reduce soil erosion, and provide a source of food and income for farmers. Some examples of agroforestry practices include alley cropping, silvopasture, and tree planting.

Overall, all of the options listed in the question are important strategies for building a climate-resilient food system in Sikkim. By implementing these strategies, farmers can help to ensure that their crops are able to withstand the effects of climate change and continue to produce food for the population.
