AgroForestry 🌲

Agroforestry is the deliberate integration of trees with crops and/or livestock on the same land unit to achieve ecological and economic benefits. Nair's classification (1993) defines three main systems: (1) Agrisilviculture — trees + crops (e.g., poplar-wheat, eucalyptus-sugarcane); (2) Silvipasture — trees + pasture/livestock (e.g., subabul-pasture); (3) Agrisilvipasture — trees + crops + livestock. Additional: aquaforestry (trees + fish), multipurpose woodlots. India has 25.32 million ha under agroforestry.

The India State of Forest Report (ISFR) is published biennially by the Forest Survey of India (FSI), Dehradun. ISFR 2021 reported: total forest and tree cover = 80.9 million ha (24.62% of India's geographic area). Forest cover alone = 71.3 million ha (21.71%). Tree cover (outside forests) = 9.6 million ha. Madhya Pradesh has the highest forest area; Mizoram has the highest percentage of forest cover (~85%).

Major silvicultural systems: (1) Clear-felling — entire crop is removed at once, area replanted (used in teak, eucalyptus plantations); (2) Shelterwood system — trees removed in stages over several years, allowing natural regeneration under the shade of residual trees; (3) Selection system — only mature trees are removed individually (used in mixed forests); (4) Coppice system — trees regenerate from root sprouts after cutting (used for fuelwood species like Dalbergia, Acacia). Selection system maintains biodiversity best.

The Indian Forest Act, 1927 (amended) classifies forests into three categories: (1) Reserved Forests — highest protection, no rights except by Forest Department permission; (2) Protected Forests — lesser protection, some rights allowed; (3) Village Forests — assigned by State Government to village communities for management. The Act also covers timber transit regulations, penalties for forest offences, and defines what constitutes forest produce (including NTFPs, bamboo, canes, mosses).

NTFPs (also called Minor Forest Produce — MFP) are forest products other than timber and fuelwood — including bamboo, cane, leaves, honey, lac, gum, resin, silk, beedi leaves, medicinal plants, and edible fruits. India's NTFPs are worth ~₹6,000–7,000 crore annually. Key NTFPs: bamboo (construction, handicrafts), lac (shellac production), tendu leaves (beedi wrapping), mahua (liquor, oil), sal seeds (cocoa butter substitute), and gum karaya (food additive).

Agroforestry and Forestry is a direct topic in IBPS AFO (Professional Knowledge), NABARD Grade A/B (Agriculture paper), ICAR JRF (Agronomy and Forestry disciplines), and all state PSC Agriculture Officer exams. The most tested items are: forest cover percentage from ISFR, silvicultural system types, Indian Forest Act categories, important tree species silviculture, and agroforestry system definitions.
