Solution
- The interior parts of semi-arid lands of the mid-latitudes in the world are the areas where extensive commercial grain cultivation takes place.
- Here the size of farms is very large and population is in small number.
- Operations of cultivation, right from ploughing to harvesting is mechanised.
- Yield per person is high as the number of people working in farms is less and lot of machines is used.
- The size of the farms is very large due to which per acre production or yield is low even though the total production is high.
- This type of agriculture is practised in Eurasian Steppes, Canadian and American Prairies, Pampas of Argentina, Velds of South Africa, Australian Downs and the Canterbury Plains of New Zealand.

Read the following passage and answer the question that follows:
| Agriculture provides livelihood to almost three - a fourth of the population of India. Indian agriculture is highly dependent on the spatial and temporal distribution of rainfall. Climate extremes such as drought and flood affect agriculture severely. An account of the impact of climate extreme viz. drought and flood, on Indian food-grain production, has been presented in this chapter. There are temporal fluctuations in food grain production and the area under the food grain. In secular terms, both of them increased up to the mid-eighties. After the mid-eighties, there is a decline in the area of food grain while maintaining an increase in production of food grain suggesting the improvement in agricultural technology and policy. There is more temporal fluctuation in the production of food grain than the area under food grain. The analysis reveals that the impact of drought on Indian agriculture is more than that of the flood. Rabi food grain production depicts better adaptability to drought than Kharif food grain production mostly due to better access to irrigation infrastructure. Among the various food, crops analyzed all except jowar can effectively face flood events. Wheat and jowar perform relatively better during drought events. Rice is the most sensitive crop to extreme climate events. Since rice is the staple food in the sub-continent, management of rice production against climate extremes needs special attention for food security and sustainability. |
