- A nine-year ICAR field study in Odisha’s Eastern Ghats shows that smallholder agroforestry can simultaneously deliver climate mitigation, livelihood security, and food production.
About Agroforestry
- Agroforestry is the practice of integrating trees with crops or livestock on the same land unit.
- Legal Framework: It is primarily governed under the National Agroforestry Policy, 2014.
- Area Estimate: India has ~25 million hectares under agroforestry, covering about ~8% of its area.
- Significance: It contributes to sustainable land use, biodiversity, and climate resilience.
Key Findings of the ICAR Study
- Carbon Sequestration: One-acre agroforestry farms sequestered up to 154.5 Mg CO₂e in nine years, demonstrating high mitigation potential on small landholdings.
- Slope Advantage: Lower-slope farms stored 73.1 Mg CO₂/acre, nearly 3 times higher than upper slopes (27.2 Mg), due to better moisture and nutrient retention.
- Species Selection: Cashew and mango emerged as dual-benefit species, combining high biomass carbon storage with strong farm incomes.
- Carbon Markets: At $20/Mg CO₂, potential carbon credits could reach ₹2.56 lakh per acre over nine years, subject to verification costs.
- Income Security: Farmers earned ₹1.1–1.13 lakh annually, while maintaining yields.
- Ecosystem Services: Farms released 112.4 Mg oxygen/acre, improving local.

Types of Agroforestry
- Agrisilviculture: This system combines crop cultivation alongside timber or fuelwood trees.
- Silvopasture: It integrates trees with grazing lands to provide fodder and shelter for livestock.
- Agrihorticulture: This model intercrops fruit-bearing trees with seasonal crops.
- Apisilviculture: It promotes flowering tree plantations to support beekeeping and pollination.
- Aqua-forestry: This system pairs tree planting around ponds with fish farming activities.
Significance of Agroforestry
- Soil & Water Conservation: Tree roots anchor the soil, reducing erosion during heavy rains; agroforestry can reduce soil erosion by up to 50% in certain regions, such as the Himalayan foothills in India.
- Environment-friendly: Agroforestry improves soil fertility through nitrogen-fixing trees, reducing dependency on chemical fertilisers by 20-30% (seen in Andhra Pradesh’s agroforestry projects).
- Supports Biodiversity: Creates habitats and corridors for pollinators like bees and birds, crucial for crop pollination and ecosystem balance.
- Agroforestry areas in Tamil Nadu have increased bird species richness by 25%.
- Carbon Sequestration: In India, agroforestry can sequester about 68 million tonnes of CO₂ annually and reduce local temperatures by around 1°C.
- Nutritional Security: It increases production of pulses and vegetables, helping address India’s average calorie deficit (~3000 calories recommended vs. actual intake).
Model Rules for Agroforestry
- These are meant for voluntary adoption by States/UTs to bring uniformity in regulating tree felling.
- National Timber Management System (NTMS): Centralised digital platform for registering agroforestry plantations and tree-felling requests. It auto-verifies girth, species, & location using uploaded data.
- State–level Committee: Formed under the 2016 Wood-Based Industries Guidelines to oversee agroforestry. It verifies applications through field agencies and periodically uploads validated data to NTMS.
- Divisional Forest Officer: Oversee verification agencies and ensure timely processing.
- Felling Procedure: NOC is auto-issued for up to 10 trees; for more, a permit is issued following verification.
- For up to 10 trees, geotagged photographs are uploaded to NTMS for identification. For more than 10 trees, physical inspection and reporting are mandatory.
Challenges Associated with Agroforestry
- Regulatory Restrictions: Only 33 tree species are allowed free harvesting and transport across states, while high-value species like teak and sandalwood require permits that cause delays.
- Research Gaps: About 10% of planting material meets quality standards, with limited large-scale research on indigenous species and fragile ecosystems like the Himalayas.
- Policy Issues: Weak marketing infrastructure and complex taxation reduce farmer profits, with multiple taxes on timber processing discouraging enterprises.
- NABARD’s Odisha pilot increased agroforestry loan uptake by 30%, showing scope for improvement.
- Extension Services: Extension services remain inadequate, benefiting mainly large farmers, whereas two-thirds of Indian farmers (small/marginal) lack access to targeted support.
- Digital Gaps: Low literacy and poor connectivity limit farmers’ knowledge of species selection and carbon markets. Digital tools like AgroConnect exist but have limited reach, constraining effective support.
Way Forward
- Regulatory Reforms: Simplify harvesting and transport rules by amending laws and implementing region-specific, time-bound permits like Tamil Nadu’s pilot, to reduce bureaucratic delays.
- Research & Development: Set up regional agroforestry research centres and invest in certified nurseries. E.g. Maharashtra’s nurseries improved sapling survival rates by 40%.
- Extension Strengthening: Promote FPOs for better market access, expand tailored credit and insurance schemes, & strengthen extension via apps and platforms like AgroConnect for farmer empowerment.
- Equitable Access: Design schemes prioritising small/marginal farmers with subsidies and technical aid, and support community-driven habitat restoration and ecological corridor creation.
- Sustainability Focus: Scale agroforestry to boost rural employment, income stability, and climate resilience, while promoting carbon credit participation through transparent benefit-sharing models demonstrated successfully in Uttarakhand.
As the saying goes, “When we plant trees, we plant hope.” Agroforestry unites climate mitigation with farmers’ livelihoods. It shows that sustainable agriculture & climate resilience can grow together on the same land.
