Q.13. Give a note how is land resource more crucial to the livelihood of the people?
Ans :- Better access to input and product markets, including savings and credit. Appropriate technologies for higher, sustainable productivity. Education and the skills to use the new technologies. Opportunities to diversify both within and beyond agriculture. For the landless, being able to access land. Improved tenancy and sharecropping arrangements, Protection of rights and development of opportunities for agricultural workers. Equitable opportunities for private sector development e.g. in high value crops for export. Better terms of trade for developing country agricultural producers. Security of tenure, whether the right to occupy a room or to develop a plot of land, plays a large part in determining access to basic infrastructure, services, employment opportunities and credit. People who are safe from eviction feel secure to improve their homes and neighbourhoods.
The legal recognition of extra-legal settlements and enterprises of the poor are powerful tools for social inclusion, and an essential basis for establishing the rule of law and more socially legitimate government in urban areas.

Q.16. Write an account on the Maize cultivation in India
Ans :- Maize is a food as well as fodder crop grown under semi-arid climatic conditions and over inferior soils. This crop occupies only about 3.6 percent of the total cropped area. Maize cultivation is not concentrated in any specific region. It is sown all over India except eastern and north-eastern regions. The leading producers of maize are the states of Madhya Pradesh, Andhra Pradesh, Karnataka, Rajasthan and Uttar Pradesh. Yield level of maize is higher than other coarse cereals. It is high in southern states and declines towards central parts.
Q.17. Write an account on cotton cultivation in India.
Ans :- Cotton is a tropical crop growth in the kharif season in semi-arid areas of the country, India lost a large proportion of cotton growing area to Pakistan during partition. However, its average has increased considerably during the last 50 years. India grows both short staple (Indian) cotton as well as long staple (American) cotton called ‘narma’ in north-western parts of the country. Cotton requires a clear sky during the flowering stage.
India ranks fourth in the world in the production of cotton after China, U.S.A and Pakistan and accounts for about 8.3 percent of production of cotton in the world. Cotton occupies about 4.7 percent of the total cropped area in the country.
There are three cotton growing areas, in. parts of Punjab, Haryana and Northern Rajasthan in north-west, Gujarat and Maharashtra in the west and plateaus of Andhra Pradesh, Karnataka and Tamil Nadu in South Leading producers of this crop are Maharashtra, Gujarat, Andhra Pradesh, Punjab and Haryana. Per hectare output of cotton is high under irrigated conditions in north-westerns region of the country. Its yield is very low in Maharashtra where it is grown under rainfed conditions.
Q.18. Write briefly on the geographical requirements for the jute cultivation and mention the major jute producing areas of India.
Ans :- Jute is used for making coarse cloth, bags, sacks and decorative items. It is a cash crop in West Bengal and adjoining eastern parts of the country. India lost large jute growing areas to East Pakistan (Bangladesh) during partition. At present, India produces about three-fifth of jute production of the world. West Bengal accounts for about three-fourth of the production in the country. Bihar and Assam are other jute growing areas. Being concentrated only in a few states, this crop accounts for only about 0.5 percent of the total cropped area in the country.
Q.19. What are the geographical requirements for tea cultivation and which are the major tea producing areas in India?
Ans :- Tea is a plantation crop used as a beverage. Black tea leaves are fermented whereas green tea leaves are unfermented. Tea leaves have rich content of caffeine and tannin. It is an indigenous crop hill in northern China. It is grown over undulating topography of hilly areas and well drained soils in humid and sub-humid tropics and sub-trophies.
In India, tea plantations started in 1840s in Brahmaputra valley of Assam which still is a major tea growing area in the country. Later on, its plantation was introduced in the sub-Himalayan region of West Bengal (Darjeeling. Jalpai and Cooch Bihar districts). Tea is also cultivated on the lower slopes of Nilgiri and Cardamom hills in Western Ghats. India is a leading producer of tea and accounts for about 28 percent of total production in the world.
India’s share in the international market of tea has declined substantially At present, it ranks third among tea exporting countries in the world after Sri Lanka and China. Assam accounts for about 53.2 percent of the total cropped area and contributes more than half of total production of tea in the country. West Bengal and Tamil Nadu are the other leading producers of tea.

(iv) Due to our use of chemical fertilizers soil fertility seriously depleted in the recent years.
(v) Deforestation is another environmental problem of land resources in India.
(vi) Alkalisation and salinisation of soils are other problems of land resources in India.
Q.22. What are the strategies followed for agricultural development in the Post Independence Period in India.
Ans : Important in strategies for agricultural development followed the post- independence period in India are as follows :
(a) The Government of India was made pressure to increase foodgrains production by-
(i) Switching over from cash crops to food crops.
(il) Intensification of cropping over already cultivated lands.
(iii) Increasing cultivated area by bringing cultivated and fallow land under plough.
(b) The above strategy helped in increasing foodgrains production, but agricultural production stagnated during the late 1950s.
(c) To overcome this problem, India were launched two important programme as –
(i) Intensive Agricultural District Programme (IADP)
(ii) Intensive Agricultural Area Programme (IAAP) But two consecutive droughts during the mid-1960s resulted in a food crisis in the country.
(d) By the mid – 1960s, Indian farmers used some new varieties (HYV) of wheat and rice which were imported from Mexico and the Philippines respectively.
(e) The country introduced package technology comprising HYVs along with chemical fertilizers in irrigated areas of Punjab, Haryana, Western Uttar Pradesh, Andhra Pradesh and Gujarat.
(f) This strategy of agricultural development paid dividends instantly and increased the food grains production at a very fast rate. It is known as “Green Revolution.”
(g) This strategy of agricultural development made the country self reliant in foodgrain production.
(h) In 1988, emphasis was given to the following sectors.
(i) Dairy farming
(iv) Livestock rearing
(i) In the 1990s, initiation of the policy of liberalisation and free mare economy are notable strategies for agricultural development.
