NCERT-aligned Class 12 Geography topic. Every item is anchored to a real location on India's map — built for boards (CBSE, ICSE, state) and UPSC aspirants.
Which agency officially MEASURES the geographical area of Indian states + districts?
The SURVEY of INDIA (SoI) — founded 1767, now under the Department of Science + Technology — is the official mapping agency that measures + records the geographical extent of all administrative units (states, districts, tehsils, blocks, villages). The areas published by SoI are the authoritative geographic measurements. However, land-revenue records maintained by states use a separate "REPORTING AREA" that can DIFFER slightly from the SoI figure — typically because the revenue records reflect surveyed + revenue-paying land only, while SoI captures every square metre including forests + wastelands + water bodies.
What does "Forests" land category include?
Area which the Government has demarcated for forest growth — NOT necessarily the same as actual forest cover. So this category can rise without actual forest gain.
What does BARREN + WASTELAND mean in Indian land-use classification?
BARREN + WASTELAND covers land that — with present-day agricultural technology — CANNOT be put to productive crop cultivation. Typical examples: rocky + barren HILL TERRAIN where soil is too thin; DESERT lands of western Rajasthan where water is insufficient; deeply eroded RAVINES (e.g., Chambal badlands); steep slopes; salt-encrusted patches. Some of this land can be RECLAIMED over time through afforestation, irrigation, or soil treatment — moving it eventually into the CULTURABLE WASTE or NET SOWN AREA category.
What is "Land put to Non-agricultural Uses"?
Settlements (rural + urban), infrastructure (roads, canals), industries, shops. Grows with secondary + tertiary sector expansion.
What is "Permanent Pastures and Grazing Lands"?
Mostly owned by village Panchayat or Government. Falls under "Common Property Resources".
What is "Area under Miscellaneous Tree Crops"?
Land under orchards + fruit trees — mostly privately owned. NOT included in Net Sown Area.
What is "Culturable Wasteland"?
Land left fallow for MORE than 5 years; can be brought under cultivation through reclamation.
What is CURRENT FALLOW in agricultural land classification?
CURRENT FALLOW refers to cultivable land that has been LEFT UNCROPPED for the current agricultural year (or for less than one year) — typically to let the soil RECOVER fertility, organic matter + soil structure. Farmers fallow fields between intensive cropping seasons because growing the same crop repeatedly without rest depletes nutrients + builds up pests. Land that remains uncropped for 1-5 years is called OTHER FALLOW; beyond 5 years it is classed as CULTURABLE WASTE. Fallow rotation is one of the oldest soil-conservation practices in agriculture.
What is "Fallow other than Current Fallow"?
Cultivable land left uncultivated for MORE than 1 year but LESS than 5 years.
What does NET AREA SOWN measure in India's land-use statistics?
NET AREA SOWN is the total physical extent of agricultural land where farmers actually planted + harvested CROPS during a given year. A field cultivated TWICE in the same year (e.g., rabi + kharif) counts ONCE for Net Area Sown. The total area of all crops sown — counting each cropping season separately — is called GROSS CROPPED AREA. The difference between the two measures gives the CROPPING INTENSITY of Indian agriculture (Gross Cropped Area / Net Area Sown × 100).
Which five LAND-USE categories EXPANDED between 1950-51 + 2019-20 in India?
India's land-use statistics show INCREASES in five categories over the seven decades since Independence: (i) FORESTED area — partly due to plantation drives, partly to administrative reclassification. (ii) AREA UNDER NON-AGRICULTURAL USES — settlements, factories, roads, railways, airports. (iii) PERMANENT PASTURES + grazing lands — modestly. (iv) CURRENT FALLOW — slightly higher. (v) NET AREA SOWN — though slowing in recent years. The CORRESPONDING DECLINES are in barren + uncultivable waste, culturable waste, + tree crops on cultivable land — partly reabsorbed into the categories above.
Four categories that have DECREASED?
Barren and wasteland, culturable wasteland, area under tree crops + groves, fallow other than current fallow.
