Dr. Sunder Raju highlights that without market infrastructure, even the most productive regenerative systems remain economically fragile

In an exclusive Agrospectrum interview, Dr. Sunder Raju, Chairman of Atria Group, emphasizes that the strongest evidence for regenerative food forests lies in market-oriented, multi-layer agroforestry systems that outperform monocultures in total productivity, income stability, and resilience—especially under climate stress. He argues that scaling is constrained less by land or capital and more by the lack of integrated supply chains capable of handling diversified outputs.

The key to overcoming long gestation periods is designing systems that generate continuous income from the outset through integrated activities like livestock and energy production. While food forests improve climate resilience and ecological outcomes, he cautions that benefits like carbon sequestration are often overstated due to weak measurement frameworks. Ultimately, he concludes that by 2040 success will be defined by widespread, economically driven adoption—where regenerative systems become the default, not a subsidized alternative.

Regenerative food forests promise to reverse land degradation while producing food. Where does the strongest empirical evidence now exist that multi-layer systems can outperform conventional agriculture on productivity, resilience, and profitability—rather than simply coexist as niche models?

The strongest empirical evidence comes from multi-layer agroforestry systems centred on perennial food crops that are actively harvested and marketed, rather than maintained solely as ecological plantings. In systems that combine trees such as moringa and fruit crops with short-cycle vegetables and fodder in the understory, field comparisons consistently show higher total output per hectare and greater income stability than single-crop farms.

These advantages become most pronounced under stress conditions, when diversified systems continue to produce usable food and biomass while monocultures suffer sharp yield losses. The evidence is clearest when performance is assessed at the system level, across seasons and crop cycles, rather than through the yield of a single crop in a single year. Designed with a production-first logic, food forests shift from niche experiments to economically competitive farming systems.

Scaling is where many regenerative concepts falter. What are the primary constraints preventing food forests from moving beyond pilot projects—land tenure, capital timelines, labor intensity, policy frameworks, or market access—and which of these is most underestimated by proponents?

Scaling fails not because food forests are biologically unviable, but because they are rarely designed as complete economic systems. The primary constraint is neither land nor capital, but the absence of downstream infrastructure capable of handling diversity at scale.

Multi-layer systems generate multiple crops in staggered volumes, and without aggregation, storage, processing, and dependable market access, that diversity becomes economically fragile. While capital timelines, labour intensity, and land tenure are important considerations, the most underestimated challenge is the depth of supply-chain and operational integration that regenerative systems require.

Through Project Chittoor, we are addressing this gap by building processing capacity, cold storage, logistics, and market linkages alongside the farms themselves—ensuring that production and monetisation scale together, rather than diverging.

Time horizons are a fundamental tension. Perennial, multi-layer systems often require years before reaching peak yields. How can farmers, investors, and governments reconcile those timelines with short-term financial and food security pressures?

This tension arises only when systems are designed to deliver value at the end of the transition rather than throughout it. Farmers cannot afford to wait several years for returns, and expecting them to do so is unrealistic. The solution is not to compress biological timelines, but to design systems in which cash flow begins early and strengthens as the landscape matures.

In Project Chittoor, this is achieved by layering agriculture with animal husbandry and decentralised solar, enabling farmers to generate steady income while perennial food systems establish. For investors and governments, this approach requires financing and support frameworks that recognise staged returns and progressive risk reduction over time, rather than evaluating performance through seasonal yields alone.

When regeneration is structured around continuous income instead of deferred promise, long time horizons cease to be a barrier.

Climate resilience is frequently cited as a core advantage. Based on field data, how do food forests actually perform under drought, flood, or heat stress compared with monoculture systems, and where do they still fall short?

Food forests do demonstrate stronger performance under climate stress, but not in the way they are often portrayed. Their primary advantage is not the elimination of losses, but the reduction of volatility. Under heat stress, multi-layer systems create cooler microclimates that protect sensitive crops and limit yield collapse. Over time, improvements in soil structure, continuous ground cover, and boundary plantings, such as timber trees, help regulate temperature, wind, and moisture across the farm.

At the same time, these systems are not inherently resilient. During the establishment phase, they can be more vulnerable than monocultures, and poor design can increase disease pressure or exacerbate waterlogging during heavy rainfall. The evidence indicates that food forests perform best once they are established and actively managed, and that resilience arises from deliberate design choices rather than from structural complexity alone.

Carbon sequestration and biodiversity gains are central to the narrative. How confident are you in current measurement and verification methods, and what risks do you see of overstating ecological benefits before robust standards are in place?

I am confident about the direction of impact, but much more cautious about the precision of measurement today. Diversified, tree-based systems clearly increase biomass and biodiversity compared to simplified monocultures, but translating those gains into accurate, farm-level numbers remains difficult. Soil carbon accumulates slowly, varies widely by context, and is expensive to measure accurately, which creates room for overstatement when claims run ahead of verification.

The real risk is that carbon and biodiversity benefits become headline promises before standards and monitoring frameworks are robust enough to support them. For this reason, these outcomes should be treated as important co-benefits rather than the primary business case, at least until measurement and verification systems mature.

Transition costs remain a major barrier for conventional farmers. What policy or financial mechanisms—subsidies, blended finance, carbon markets, insurance reform—would most effectively de-risk the shift to multi-layer regenerative systems?

The biggest challenge is not the absence of schemes, but the fact that most existing policies are designed for single-crop, single-season agriculture. Crop insurance under PMFBY protects against extreme downside, but it struggles to recognise diversified systems because assessment and payouts remain tied to individual crops. Institutional credit through NABARD and priority sector lending does exist, yet it is structured around short repayment cycles that do not align with perennial or multi-layer systems.

 What truly de-risks the transition is support that prioritises income continuity rather than inputs alone. Long-tenure credit with interest subvention during the establishment phase, public investment in shared infrastructure such as packhouses and cold storage, and assured offtake for value-added outputs help stabilise cash flows in the years when biological systems are still maturing. Through Project Chittoor, we are using on-ground experience to advocate for policy shifts that recognise systems rather than crops and that support farmers through the transition, not just at the point of planting.

Food forests challenge dominant assumptions about efficiency and mechanization.Do you see future productivity gains coming primarily from biological complexity itself, or from integrating advanced technologies such as AI, remote sensing, and precision management into these systems?

Biological complexity is what creates resilience, but it does not scale on its own. Left unmanaged, complexity increases labour and decision-making burden. The real productivity gains will come from integrating technology so these systems can be managed with the same discipline as any other production asset. Remote sensing, soil and weather monitoring, farm management software, and farmer support applications allow multi-layer systems to be planned, monitored, and adjusted in real time. In our experience, technology does not replace ecological design, it makes it executable at scale. Without these tools, food forests remain high-touch and difficult to replicate. With them, they become dependable, scalable production systems.

Looking toward 2040, not just 2030, success will be judged by adoption, not ideals.What would signal that regenerative food forests have crossed from alternative agriculture into the mainstream—and what would constitute failure despite good intentions?

By 2040, success will look boring, and that is a good thing. Food forests will have crossed into the mainstream when farmers adopt them without the need for persuasion, grants, or advocacy, simply because they are safer and more reliable than conventional options. Banks will lend to these systems without hesitation, insurers will price them rationally, and infrastructure will be built to support diversity rather than single crops.

These systems will be evaluated on income stability and long-term productivity, not treated as special cases. Failure, despite good intentions, would look like continued dependence on pilots, subsidies, and narratives that do not survive contact with real economics. If regenerative systems remain impressive in theory but fragile in practice, or if carbon claims run ahead of credibility and erode trust, adoption will stall.

Ultimately, regeneration succeeds when it becomes a default choice driven by economics, not an alternative sustained by belief.
