- There are several restrictions imposed by governments through forest acts etc., which hinder the free movement of tribes and practice of shifting cultivation.
- Shifting cultivation is sustainable in nature, hence it is unable to meet with the market demand and therefore there is no scope for it in the increasing globalised markets.
- With the infiltration of non tribals in the tribal areas, tribals are adopting to modem agricultural practices which are more productive and environmentally sustainable.
- To support a small population, a huge land resource base is required, ultimately it leads to soil erosion and land degradation.
(ii) Market gardening is practiced near urban areas. Why?
Ans. Market gardening is specialised in the cultivation of high value crops such as vegetables, fruits and flowers, solely for the urban markets. It is practised near urban areas because:

- The crops are costly, hence they need to be situated close to a market where people have high purchasing power and also demand for high valued crops. In such situation urban areas are the perfect markets.
- These crops are perishable in nature; hence farms cannot be situated far away from the main market.
(iii) Large scale dairy farming is the result of the development of transportation and refrigeration.
Ans. Market gardening is specialised in the cultivation of high value crops such as vegetables, fruits and flowers, solely for the urban markets. It is practised near urban areas because:
- Dairy products require quick and suitable transportation as these items are perishable.
- The development of transportation and refrigeration have increased the duration of storage of various dairy products.
- Modem transportation such as refrigerated trucks, ships with special cargoes and faster means of transportation like airways provide with adequate facilities, which allow transportation of dairy products to far off markets without spoilage.
