Key Details
The OECD’s Integrating Ecosystem Services from Trees and Forests into Agriculture in OECD Countries shows that financial support alone does not determine success. Incentives must reflect farm economics, ecological conditions and the period for which environmental benefits can be maintained.
Area | Finding |
|---|---|
Policy mix | About 60% of the nearly 100 identified measures use subsidies, 14% provide information or advisory support and 12% support carbon credits |
Large-scale planting | Carbon-focused planting measures provide an average of about USD 1,800 per hectare, excluding outliers |
Incremental improvements | Measures supporting tree maintenance or smaller changes average about USD 235 per hectare annually, excluding outliers |
Implementation risks | Water stress, unsuitable species, uncertain farm returns, inadequate seedlings and reversal of stored carbon can weaken results |
Trees Can Improve Farms, but Location Matters
Trees incorporated into agricultural landscapes can reduce erosion, improve water retention, support pollinators and natural pest control, create favourable microclimates and diversify farm income. The report also cites research on agroforestry for soil conservation and productivity in western India.
The benefits are not automatic. Planting unsuitable species or adding trees where water is already scarce can place further pressure on soil and water resources. Large-scale conversion of farmland may also reduce agricultural production or shift environmental pressures elsewhere.
For India, this reinforces the need to distinguish among:
agroforestry on productive farms;
trees on field boundaries and marginal land;
restoration of degraded land; and
naturally open ecosystems where additional tree cover may be ecologically inappropriate.
Uniform Subsidies May Produce Uneven Results
Farmers’ willingness to plant or retain trees depends on land productivity, farm size, labour requirements, expected income and the time taken for trees to generate returns. A payment that is adequate on low-productivity land may be insufficient on more valuable farmland—or may overcompensate farmers elsewhere.
The OECD paper therefore favours incentives adapted to local conditions, supported by farmer engagement, technical advice and markets for agroforestry products. It also highlights a less visible policy issue: retaining existing trees may provide high public value even when removing them is more profitable for an individual farmer.
Carbon Credits Must Address Permanence
Trees store carbon only while that carbon remains outside the atmosphere. Fire, disease, harvesting or later land conversion can reverse the claimed benefit, while fossil-fuel carbon dioxide can remain in the atmosphere for much longer than typical forestry-credit commitments.
Forest-carbon programmes therefore need:
sufficiently long maintenance obligations;
monitoring beyond the initial payment period;
safeguards or reserve mechanisms for possible carbon loss; and
clear responsibility when land ownership changes.
This is directly relevant as India develops carbon markets and land-based mitigation projects. Crediting the act of planting without tracking survival and continued storage would overstate the climate benefit.
Seedling Supply Is Part of Policy Design
Ambitious planting targets require enough high-quality, genetically diverse and locally suitable planting material. The report recommends strengthening nurseries, improving seed sourcing and giving farmers practical advice on species selection.
The objective should not be the largest number of seedlings distributed, but surviving trees that suit local farming systems and ecological conditions.
What Is Agroforestry?
Agroforestry integrates trees with crops or livestock on the same land. It differs from converting farmland entirely into forest because agricultural production generally continues alongside tree-based products and environmental services.
Policy Relevance
Payments should reflect local opportunity costs. India’s agroforestry incentives need to account for differences in land value, farm size, water availability and expected agricultural income.
Environmental safeguards must precede planting. Site and species screening can prevent water stress, invasive planting and damage to grasslands or other open natural ecosystems.
Existing farm trees deserve policy attention. Incentives should cover retention and management, not only the planting of new trees.
Carbon claims require long-term verification. Survival rates and continuing carbon storage matter more than initial plantation figures.
Agriculture and environment authorities need shared implementation systems. Joint data, extension services and monitoring can reduce conflicting objectives and administrative burdens.
Nursery capacity determines delivery quality. Expanding certified, diverse and regionally suitable planting material is essential for scaling agroforestry responsibly.
