Differentiate between Barren land, Waste land and Culturable Waste land.
How would you distinguish between Net sown area and Gross cropped area?
Why is the strategy of increasing cropping intensity important in country like India?
Or
Classify rainfed farming on the basis of adequacy of soil moisture during cropping season.
Or
Distinguished between ‘Dryland farming and Wet land farming.’
Or
What is the difference between Dryland and Wetland farming.
Effects :
Technology helps to raise the yield per hectare and total output per unit area. It is done by increasing land use intensity.
How do you measure total cultivable land?The total cultivable land can be measured by adding up net sown area, all fallow lands and culturable waste land.
The total cultivable land can be measured by adding up net sown area, all fallow lands and culturable waste land.
What are the different types of environmental problems of land resources in India?
Many serious problems of land resources arise due to degradation of land. It leads to depletion of soil fertility. A large area of agricultural land has lost its fertility due to alkalisation and salinisation of soils and water logging. It has affected about 15 lakh ha. of land. Excessive use of chemicals such as insecticides and pesticides has led to their concentration in toxic amount in the soil profile. Fallow land has declined. Rainfed areas experience degradation by soil erosion by water and wind.
What are the important strategies for Agricultural development followed in the post independence period in India?
Or
“After independence various important strategies were adopted for agricultural development in India.” Substantiate the statement.
After Independence, the immediate goal of the Government was to increase foodgrains production by (i) switching over from cash crops to food crops ; (ii) intensification of cropping over already cultivated land ; and (iii) increasing cultivated area by bringing cultivable and fallow land under plough. Initially, this strategy helped in increasing foodgrains production. But agricultural production stagnated during late 1950s. To overcome this problem, Intensive Agricultural District Programme (IADP) and Intensive Agricultural Area Programme (IAAP) were launched. But two consecutive droughts during mid-1960s resulted in food crisis in the country. Consequently, the foodgrains were imported from other countries.
