The correct answer is: a) Remote communities.
Shifting cultivation, also known as swidden agriculture or slash-and-burn agriculture, is a traditional agricultural system in which the land is cleared by cutting and burning, and then cultivated for a short period of time. After the land has been used for a few years, it is left fallow to regenerate. This type of agriculture is often used in remote communities where there is little land available for cultivation.
Large-scale commercial farming is a type of agriculture in which large areas of land are used to grow crops or raise livestock. This type of agriculture is often used to produce food for export or to feed large populations.
Export-oriented crops are crops that are grown primarily for sale to other countries. These crops are often grown in large-scale commercial farms.
Urban populations are people who live in cities. Urban populations are often dependent on imported food, as there is limited space for agriculture in cities.
In conclusion, shifting cultivation plays a role in food production for remote communities. It is a traditional agricultural system that is often used in areas where there is little land available for cultivation.
