• Agriculture: The introduction of new crops like tea and potatoes led to a change in the cropping pattern in Sikkim. Tea became a major cash crop, and potatoes became a staple food. This led to a change in the way land was used, as more land was devoted to the cultivation of these crops.
• Trade patterns: The introduction of new crops also led to a change in trade patterns. Sikkim began to export tea and potatoes to other parts of India and the world. This led to an increase in economic activity in Sikkim.
• Land use: The introduction of new crops also led to a change in land use. More land was devoted to the cultivation of tea and potatoes, which led to a decrease in the amount of land available for other uses, such as grazing and forest cover.

Overall, the introduction of new crops by the British had a significant impact on Sikkim’s agriculture, trade patterns, and land use.
