Agroforestry is a vital necessity for India right now

Introduction

Agroforestry, as the term implies, is a practice that integrates agriculture and forestry by growing trees or shrubs alongside crops. This combination fosters a more biodiverse, productive, and sustainable land-use system. The rapid growth of the global population has intensified the pressure on land resources. In recent decades, agricultural intensification and farm consolidation have led to the standardization of farming methods and a decline in agrodiversity. This has paved the way for the development of diverse agroforestry systems, which offer resilience under water scarcity while boosting production and profitability. Agroforestry is increasingly recognized as a vital tool for enhancing rural livelihoods, protecting ecosystems, and ensuring food security through sustainable practices. It represents a dynamic and ecologically sound approach to natural resource management, integrating tree species into agricultural landscapes. This practice promotes production diversification and sustainability, offering economic, environmental, and social benefits [Kumar et al., 2024] [5] . Historically, farmers across the world have practiced the cocultivation of trees and crops, and this remains a common practice in many regions. Agroforestry is practiced globally and is critical for mitigating climate change impacts. In India, land degradation and deforestation threaten long-term food security, sustainable development, and peace. Environmental degradation in key regions has contributed to decades of social unrest and conflict. Despite its potential, many developing countries, including India, have not prioritized agroforestry due to gaps in knowledge, economics, information, and technology. Agroforestry is practiced all over the world, and it is critical for mitigating the effects of climate change. Land degradation and deforestation jeopardize India's long-term food security, sustainable development, and peace chances. The substantial deterioration of environmental services in various major sections of the country is one of the root causes of decades of social struggle and violence. However, due to a lack of knowledge, economics, information and technology, many developing nations like India, do not give it appropriate and effective attention and neglect to practice. Adopting a long-term strategy for addressing food poverty necessitates more sustainable farming techniques. Crop failure is becoming more common in monoculture farming www.extensionjournal.com systems due to increasing weather anomalies. Specialized crop production methods, in which a small number of seasonal crops occupy huge arable areas, result in increased biotic and abiotic pressures in the agro-ecosystem. Addressing food insecurity requires a shift toward sustainable farming techniques. Monoculture farming systems, which dominate large areas of arable land, are increasingly vulnerable to crop failure due to climate anomalies. Such systems exert significant biotic and abiotic pressures on the agro-ecosystem. Climate change exacerbates the impacts of droughts, floods, and pest outbreaks, and farmers' ability to adapt to these challenges will determine their ability to sustain their livelihoods. Agroforestry offers various adaptation strategies, improving agricultural landscapes through carbon sequestration, wood energy, enhanced soil fertility, and better local climatic conditions. The advantages of agroforestry are well-documented: it helps alleviate poverty among farmers by increasing the production of wood and other tree products for both home use and sale. Additionally, agroforestry enhances food security by restoring soil fertility, thereby improving the productivity of food crops. This holistic approach not only supports agricultural yields but also promotes environmental sustainability. It also plays a crucial role in reducing deforestation and stabilizing soil against erosion. An appropriate mix of tree and crop species can enhance the resilience of agricultural land, enabling it to withstand extreme weather events such as floods and droughts, as well as the broader impacts of climate change. Thus, agroforestry can be confidently regarded as a vital tool for building resilience among farmers and rural communities in the face of climate change and natural disasters. This integrated approach not only protects ecosystems but also supports the livelihoods of those who depend on the land. For India, agroforestry represents a crucial alternative for achieving the ambitious goal of increasing forest and tree cover to 33% from the current level of less than 25%, as outlined in the National Forest Policy of 1988. Successful examples of agroforestry practices can be found among farmers, such as those in Bareilly district, Uttar Pradesh, where cultivating Eucalyptus and Poplar alongside traditional crops led to net profits increasing by 2.5 to 3 times over seven years. However, such instances remain sporadic. Despite its potential to address climate change, enhance food security, and improve rural livelihoods, many farmers remain hesitant to adopt agroforestry for various reasons, including lack of knowledge, access to resources, and perceived risks. Addressing these barriers is essential for promoting wider adoption of this sustainable land-use system. Finally, the long-awaited development of a National Agroforestry Policy is underway. The Indian Council of Agricultural Research (ICAR) is actively discussing its scope and has begun compiling data from various regions across the country to support this policy initiative. This effort aims to provide a structured framework that encourages the adoption of agroforestry practices, ensuring they are tailored to the diverse ecological and socioeconomic contexts of India. By establishing this policy, the government hopes to enhance the benefits of agroforestry for farmers, the environment, and the economy as a whole.

India is situated in a region recognized as the cradle of agroforestry, having been a pioneer in the scientific advancements related to this practice. The time has come to develop this sector for income and employment generation, as agroforestry is uniquely positioned to drive sustained growth of 4% in Indian agriculture. It offers a viable solution for optimizing farm productivity, particularly as landholding sizes continue to shrink. By embracing and promoting agroforestry, India can enhance both agricultural resilience and economic opportunities for rural communities.

Why We Need Agroforestry

The increasing population will significantly raise the demand for household wood products, paper, packaging materials, and firewood. Relying solely on forests to meet this growing demand is not feasible; thus, private agroforestry has become essential. Currently, India's per capita consumption of paper and paperboard is less than 10 kg, compared to 72 kg in China. Additionally, timber productivity in India stands at only 0.7 cubic meters per hectare per year, while the global average is 2.1 cubic meters per hectare per year. With forests covering only 69 million hectares-19.5% of the country's area-the availability of forest land per person in India is among the lowest globally, at just 0.08 hectares. This is significantly less than the average of 0.5 hectares for developing countries and 0.64 hectares worldwide. The demand for timber was 85 million cubic meters in 2008, and it is expected to exceed 153 million cubic meters by 2020. However, the projected supply of wood from forests is only around 60 million cubic meters by that same year. This disparity indicates that India will need to rely on imports or, alternatively, develop agroforestry on private and community lands to meet its growing wood requirements. Embracing agroforestry can provide a sustainable solution to fulfill these demands while enhancing rural livelihoods and conserving the environment. In the face of increased cultivation costs, labor shortages, and rising farm wages, many farmers are shifting towards less investment and labor-intensive practices, such as shortterm commercial crops and forestry plantations. Agroforestry systems tend to be predominantly practiced by larger farmers who have alternative sources of income beyond agriculture. For small farmers, relying solely on agroforestry can be challenging, as they require annual returns to sustain their livelihoods. However, some small farmers have begun to adopt agroforestry by intercropping food crops between tree rows for the first one to two years, until the trees mature. This approach not only provides immediate food security but also contributes to wood security in the long term. Such practices highlight the potential for agroforestry to enhance both agricultural productivity and sustainability, benefiting smallholders and fostering resilience in rural communities. Leucaena and Eucalyptus trees are widely cultivated in Andhra Pradesh, providing farmers with a reliable source of income. The yield from each acre typically ranges from 25 to 30 tonnes every four years, as these trees are harvested at that interval. The wood is primarily used in the paper industry, as well as for plywood, particle boards, and wood veneer. Additionally, waste wood is utilized in biomass www.extensionjournal.com power generation plants as a substitute for coal and other fossil fuels, helping to reduce greenhouse gas emissions. Many progressive farmers are increasingly inclined to adopt the agroforestry model as a means to enhance farm productivity and profitability, supporting sustainable agricultural practices while securing their livelihoods.

Carbon pool in different agroforestry system

Agroforestry systems, as a land-use practice, have the potential to reduce atmospheric carbon dioxide concentrations. Recent projections indicate that the global area under agroforestry will expand significantly in the near future, which will likely have a profound impact on the flux and long-term storage of carbon in the terrestrial biosphere (Dixon, 1995) [3] . Agroecosystems are integral to the global carbon cycle, storing approximately 12% of the world's terrestrial carbon (Smith et al., 1993; Dixon, 1995) [14,3] . Carbon is accumulating in the atmosphere at a rate of 3.5 petagrams (Pg) per year (1 Pg = 10^15 grams or billion tons), with the largest share resulting from the burning of fossil fuels and the conversion of tropical forests into agricultural land (Paustian et al., 2000) [10] . While increased atmospheric carbon flux can lead to some positive effects, such as improved plant productivity, negative climate changes-such as rising temperatures, more frequent droughts, and floods-are often more consequential. Agriculture, forestry, and other land uses (AFOLU) are bidirectional in their ability to absorb and release carbon dioxide. Land used under different practices, land use changes, and forestry practices (LULUCF) were responsible for 12.5% of all human-caused carbon based emissions (Tripathi et al., 2023) [16] . Land-use management practices, like agroforestry systems, which combine tree cultivation with agricultural crops, play a crucial role in mitigating climate change. These systems absorb excess carbon dioxide, which is then used in photosynthesis by trees. Carbon is stored in both tree biomass and soil, which not only contributes to carbon sequestration but also helps protect natural carbon sinks. Agroforestry systems improve land productivity while providing forest products on agricultural lands, further supporting sustainable land use and climate change mitigation. India has achieved self-sufficiency in food production, and now the focus should shift toward ecological sustainability, conserving fossil fuels, and addressing the growing demand for wood driven by population growth and economic development. Agroforestry systems have the potential to sequester significant amounts of carbon, thereby helping to mitigate the risks associated with greenhouse gas emissions. Implementing agroforestry can be particularly effective on large barren lands and along farm boundaries, enhancing soil fertility and promoting water conservation. There is substantial potential for agroforestry to address various ecological issues, support biomass production, provide cattle fodder, and supply diverse outputs for industries, while also generating employment opportunities.

Key Benefits of Agroforestry

• Food Supply: Meet the needs of the increasing population.

• Increased Forest Cover: Enhance forest areas outside of traditional forest boundaries.

• Soil Improvement: Boost soil productivity, reduce erosion, and establish sustainable land management practices. • Economic Upliftment: Improve the social and economic status of rural farmers. • Consistent Raw Material Supply: Ensure a steady supply of raw materials for forest-based industries.

Agroforestry and Climate Change Mitigation and Adaptation

In India, emerging evidence suggests that agroforestry systems offer a promising land-use approach for enhancing and conserving aboveground and soil carbon (C) stocks, thereby contributing to climate change mitigation (Kumar et al., 2020) [6] . The average potential of agroforestry for carbon storage has been estimated at 25 tons of carbon per hectare across 96 million hectares (Sathaye and Ravindranath, 1998) [13] . This would translate to a total potential of about 2400 million tons of carbon stored through agroforestry in India. Other estimates indicate that agroforestry occupies 8.2% of the total reported geographical area (305.6 million hectares) and contributes 19.3% of the total carbon stock across various land uses (2755.5 million tons of carbon). The higher productivity potential of agroforestry systems may be attributed to the efficient capture of growth resources such as light and water, as well as enhanced soil fertility. Numerous studies conducted in different parts of India have shown that agroforestry can be more profitable for farmers compared to traditional agriculture or forestry on the same piece of land (Tokey, 1997) [15] . Recent projections indicate that the area under agroforestry in India is expected to increase significantly in the near future (NRCAF, 2006) [9] . The carbon sequestration potential of various agroforestry systems depends on the specific practices implemented. Carbon storage estimates for different agroforestry systems vary widely, ranging from 12 to 228 megagrams (Mg) of carbon per hectare in different regions of the world (Ram Newaj and S.K. Dhyani, 2008) [12] . Agroforestry plays a vital role in both mitigating and adapting to climate change through several key mechanisms:

• Impact Reduction: Integrating trees into agricultural systems can help diminish the effects of climate change on agriculture while also reducing agriculture's contribution to greenhouse gas emissions.

Issues and Challenges in Agroforestry

Although, agroforestry presents a promising approach for sustainable land use, it faces significant challenges related to knowledge, economics, land tenure, policy support, and environmental conditions. Overcoming these challenges www.extensionjournal.com requires concerted efforts from governments, institutions, and communities to promote education, provide economic incentives, clarify land rights, and develop supportive policies that encourage the widespread adoption of agroforestry systems.

• Short-Term Focus: Agroforestry is inherently a longterm investment, but many farmers prioritize shortterm, hassle-free gains, leading them to prefer horticulture over agroforestry.

Economic Constraints

• Agroforestry systems require significant initial investment for tree planting, management, and maintenance, which can be costly for farmers, particularly in developing countries. • Many farmers, especially those in low-income regions, lack access to affordable credit, making it difficult to cover the upfront costs of agroforestry. • Agroforestry yields delayed returns as trees take time to mature, adding to the economic burden, particularly compared to traditional agriculture that provides quicker financial returns. • Limited market access for agroforestry products (e.g., timber, fruits, medicinal plants) further complicates the economic viability of agroforestry.

Land Tenure Issues

• In many rural and forested regions, land tenure systems are unclear, insecure, or complex, discouraging farmers from investing in agroforestry. • Without guaranteed ownership or long-term rights to land, farmers may be hesitant to commit to long-term agroforestry projects that take decades to yield benefits. • Unclear land tenure can also lead to conflicts over land use and ownership, complicating the integration of agroforestry into rural livelihoods.

Policy and Institutional Support

• Land-use, agriculture, and forestry policies are often fragmented and lack coordination, making it difficult to implement effective agroforestry systems.

Conclusion

The world's population has been rapidly increasing, putting additional strain on land. Agricultural intensification and farm consolidation have resulted in significant standardization of farming techniques and agro-diversity during the last few decades. As a result, a diverse agroforestry system has arisen to provide resilience under limited water conditions while also increasing production and profitability. Agroforestry is thought to be a significant tool and future of global land use for improving rural people's livelihoods, safeguarding ecosystems, and assuring food security through sustainable ways. Agroforestry systems in India play a vital role in meeting the basic needs of rural communities. They contribute significantly to increasing overall productivity while addressing the domestic demands of farmers and the growing needs of our population for food grains, fuelwood, timber, and more. As these demands continue to rise, current availability and supply remain insufficient. With over 200 million people heavily reliant on forests for their subsistence and livelihoods, it is clear that traditional farming practices alone cannot meet these needs. Agroforestry emerges as a realistic and effective approach to not only conserve natural resources but also help achieve the goal of increasing forest www.extensionjournal.com cover to 33% from the current level of 23.81%. By promoting agroforestry, we can enhance sustainability, bolster rural economies, and support the resilience of communities dependent on agriculture and forestry.
