Context:
Agroforestry presents a transformative opportunity for rural India by enhancing biodiversity, boosting farmer incomes, promoting carbon capture, and supporting ecological restoration.
Agroforestry
Agroforestry is a holistic land-use approach that combines agricultural practices with forestry techniques to create diversified, sustainable, and economically viable landscapes.
Key Goals:
- Improve land productivity and ecological restoration
- Optimize resource use for sustainable outputs
- Generate employment in rural areas
- Provide raw materials for small-scale rural industries
- Expand food production to meet population growth
- Enhance diet diversity for improved nutrition
- Ensure fodder availability for dairy and meat production
Types of Agroforestry Systems
- Agrisilvicultural Systems:
- Integration of crops and trees on the same land.
- Enhances soil fertility and provides multiple income streams.
- Silvopastoral Systems:
- Incorporates trees into grazing lands.
- Offers shade and shelter to livestock and improves soil quality.
- Apiculture with Trees:
- Nectar-producing trees attract bees, aiding pollination.
- Promotes honey production as an added income source.
- Aquaforestry:
- Trees planted around water bodies like fish ponds.
- Stabilizes pond banks, improves water quality, and supports sustainable aquaculture.
Benefits and Significance
- Soil and Water Conservation:
- Tree roots prevent soil erosion—up to 50% reduction noted in regions like the Himalayan foothills.
- Environmental Gains:
- Nitrogen-fixing trees enhance soil health, reducing the need for chemical fertilizers by 20–30%, as seen in Andhra Pradesh.
- Biodiversity Conservation:
- Agroforestry landscapes act as habitats for pollinators and birds, enhancing ecosystem resilience.
- Tamil Nadu’s agroforestry zones have seen a 25% rise in bird species diversity.
- Climate Action – Carbon Sequestration:
- India’s agroforestry systems can absorb about 68 million tonnes of CO₂ annually and contribute to local temperature reduction (up to 1°C).
- Nutritional Security:
- Increases output of pulses and vegetables, helping mitigate India’s calorie intake shortfall (recommended ~3000 calories per person/day).
Key Challenges
- Regulatory Barriers:
- Free movement of only 33 tree species across states; high-value trees like sandalwood and teak require permits, delaying farmer benefits.
- Research & Quality Issues:
- Only around 10% of planting materials meet the required quality standards.
- Limited research on native species and fragile zones like the Himalayas.
- Policy and Market Limitations:
- Fragmented marketing systems and complex taxation structures reduce farmer profitability.
- Multiple taxes on timber discourage agroforestry-based enterprises.
- NABARD’s pilot in Odisha demonstrated a 30% rise in agroforestry loans, indicating potential with better policy support.
- Inadequate Extension Services:
- Small and marginal farmers (who make up 66% of all farmers) often lack access to customized training and advisory services.
- Digital Divide:
- Poor internet access and low digital literacy prevent farmers from using tools like AgroConnect to access species recommendations, weather forecasts, and carbon market insights.
