To address fodder shortages, especially during winters, Sikkim promotes:

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

Sikkim is a mountainous state in India with a high altitude and a cold climate. This makes it difficult to grow fodder crops, and the state experiences fodder shortages, especially during winters. To address this issue, the government of Sikkim promotes a number of initiatives, including:

• Fodder banks: These are government-run facilities that store fodder crops, which can be distributed to farmers during times of shortage.
• Silage production: Silage is a type of fodder that is made by fermenting green plants. It is a high-quality feed that can be stored for long periods of time, and it is particularly useful during winter when fresh fodder is scarce.
• Import of fodder from other states: Sikkim imports fodder from other states, such as Uttar Pradesh and Haryana, during times of shortage. This helps to ensure that farmers have enough feed for their livestock.

These initiatives have helped to reduce fodder shortages in Sikkim. However, the state still experiences some problems during winter, when the demand for fodder is high. The government is working to improve the situation by increasing the production of fodder crops and by developing new ways to store and preserve fodder.
