India's literacy rate is at 74.04%. Kerala is the most literate state in India, with 93.91% literacy. Bihar is the least literate state in India, with a literacy of 63.82%.
4. Population Growth
Phase 1 : 1901-1921 Stagnant growth
Phase 2 : 1921-1951 Steady population growth
Phase 3 : 1951-1981 High growth rate
Phase 4 : 1981-2019 Remained high but slowed down (Due to decrease in crude birth rate)
5. Density of population increased from 117 persons/ sq km in 1951 to 382 persons/sq km in 2011 6. Mumbai is most populated [Mumbai > Delhi > Kolkata] 7. Density of Population [Delhi > Chandigarh > Pondi > D&D > Bihar > West Bengal > Kerala > UP]
11,297 persons in the National Capital Territory of Delhi Arunachal Pradesh has least density Eastern Region- 625(Highest)
Highest in Kerala in peninsular India (Bihar in north after NCT)
Physiological density = total population / net cultivated area
Agricultural density = total agricultural population / net cultivable area

Land Resources and Agriculture
1. Classified as forest - identified and demarcated for forest growth [Area (Notified) vs Cover]2. Barren and Wastelands - cannot be brought under cultivation with the available technology 3. Land put to Non-agricultural Uses - Land under settlements (rural and urban), infrastructure (roads,
canals, etc.), industries, shops, etc. 4. Area under Miscellaneous Tree Crops and Groves (Not included in Net sown Area) - land under
orchards and fruit trees 5. Culturable Wasteland - Left fallow (uncultivated) for more than five years. It can be brought under
cultivation after improving it through reclamation practices. 6. Current Fallow - Left without cultivation for one or less than one agricultural year. The land recoups the
lost fertility through natural processes. 7. Net Area Sown - The physical extent of land on which crops are sown and harvested is known as net sown
area
8. Share of area under forest, area under non-agricultural uses, current fallow lands and net area sown have
shown an increase. 9. common property resources - public spaces where a group larger than a household or family unit
exercises rights of use and carries responsibility of management 10. Cropping Intensity in percentage = GCA/NSA 11. Cropping Seasons in India
12. Types of Farming
Irrigated - Protected and productive
Rainfed area
Dryland Farming
ragi, bajra, moong, gram and guar (fodder crops)

14. Land-human ratio in the country is only 0.31 ha which is almost half of that of the world as a whole (0.59 ha) 15. More than 60 per cent of the ownership holdings have a size smaller than one (ha). Furthermore, about 40
per cent of the farmers have operational holding size smaller than 0.5 hectare (ha). 16. Small and marginal farmers with less than two hectares of land account for 86.2% of all farmers in India,
but own just 47.3% of the crop area 17. India ranked first in the production of pulses and jute in 2011. It is the second largest producer of rice,
wheat, groundnut, sugarcane and vegetables. 18. Irrigation covers only about 33 per cent of the cultivated area in India 19. Rice needs high temperature, high humidity and rainfall. 20. Wheat requires moderate temperature and rainfall during growing season and bright sunshine at the time of
harvest. 21. Millets are hardy crop that needs low rainfall and high to moderate temperature22. Maize requires moderate temperature, rainfall and lots of sunshine. It needs well-drained fertile soils.23. Cotton requires high temperature, light rainfall, two hundred and ten frost-free days and bright sunshine for
its growth.24. Jute was also known as the ‘Golden Fibre’. It grows well on alluvial soil and requires high temperature,
heavy rainfall and humid climate.25. Coffee requires warm and wet climate and well drained loamy soil.26. Tea requires cool climate and well distributed high rainfall throughout the year for the growth of its tender
leaves. It needs well-drained loamy soils and gentle slopes.
Water Resources
1. Water Resources in India
4% of world water resources for 16% population
Surface Water Resources
Rivers - 1,869 cubic km but only 32% usable
Replenishable groundwater - 432 cubic km
Lagoons and Backwaters - used for fishing and irrigating certain varieties of paddy crops, coconut, etc.
Agriculture 89% surface water & 92% ground water
2. High yielding varieties of crops need regular moisture supply 3. Over withdrawals in some states, like Rajasthan and Maharashtra, has increased fluoride concentration in
groundwater, and this practice has led to increase in concentration of arsenic in parts of West Bengal andBihar
4. Watershed management basically refers to efficient management and conservation of surface andgroundwater resources.
5. Haryali is a watershed development project sponsored by the Central Government which aims at enablingthe rural population to conserve water for drinking, irrigation, fisheries and afforestation. The Project isbeing executed by Gram Panchayats with people’s participation.
6. Neeru-Meeru (Water and You) programme (in Andhra Pradesh) and Arvary Pani Sansad (in Alwar,Rajasthan) have taken up constructions of various water -harvesting structures
7. India’s National Water Policy, 2002
Irrigation and multi-purpose projects should invariably include drinking water component, whereverthere is no alternative source of drinking water.
Providing drinking water to all human beings and animals should be the first priority.Measures should be taken to limit and regulate the exploitation of groundwater.Both surface and groundwater should be regularly monitored for quality. A phased programme
should be undertaken for improving water quality.The efficiency of utilisation in all the diverse uses of water should be improved.Awareness of water as a scarce resource should be fostered. Conservation consciousness should
be promoted through education, regulation, incentives and disincentives.
8. Jal Kranti Abhiyan (GOI) 2015-16 is designed to provide livelihood and food security through water security.
