As climate stress, rising input costs, and nutritional concerns mount, a quiet shift is taking root in India’s fields: farmers and policymakers are once again valuing local, traditional seeds — often called landraces or desi seeds — as critical tools for food security, resilience, and nutrition. Recent scientific studies and international reports are giving these age-old practices renewed credibility at a time when debates over genetically modified (GM) seeds remain polarised.
“Local seeds are not nostalgia — they are adaptation,” said Dr Meera Patel, an agronomist with a farmer-led seed network in Maharashtra. “They perform reliably where the Green Revolution varieties and even some biotech options struggle — on marginal soils, with erratic rains, and in low-input systems.”
Science backs the resilience of landraces
A 2024 on-farm survey published in Scientific Reports documented hundreds of landraces conserved by farmers across India and concluded that on-farm crop diversity plays a significant role in sustaining agro-ecosystems, livelihoods, and local food security — especially under changing environmental conditions. (Nature)
This finding aligns with a broader literature showing that genetic diversity at the farm level increases system resilience, giving farmers a buffer against unexpected weather extremes — an increasingly frequent reality on the subcontinent.
Nutrition and public-health: millets and landrace crops
Beyond resilience, nutrition is a central argument for reviving local seeds. Nutritional reviews highlight millets and other indigenous grains as rich sources of protein, fibre, minerals, and antioxidants — qualities particularly relevant for diet-related illnesses that India still battles.
Health benefits of local seeds over GMO seeds
One of the increasingly recognised advantages of local, traditional seed varieties is the superior nutritional and health profile they often carry compared with commercial hybrids — and in many cases compared to monoculture GM varieties as well.
- A study of rice landraces from India’s northeast found that local varieties harbour rich genetic diversity and associated traits such as enhanced micronutrient content and adaptation. (PMC)
- Reviews of Indian landraces emphasise they carry higher fibre, richer micronutrient profiles (especially iron and zinc), and bio-active compounds (polyphenols, anthocyanins) known for protective health effects. (ResearchGate)
- Meanwhile, the literature on GM crops emphasises that while GM technologies can deliver yield or pest-resistance gains, they are seldom developed primarily for nutritional richness; and some reviews caution that long-term health or ecosystem effects need further study. (PMC)
In short: by choosing and preserving local seed varieties, farmers and consumers can get foods that are more nutrient-rich per unit, aligned with traditional dietary patterns, and better suited to combating micronutrient deficiencies (often called “hidden hunger”) that still afflict large segments of India’s population.
Why GMOs Should Be Given Less Priority Over Local Seed Varieties
While GMOs have their role, a number of scientific reviews and policy studies suggest they warrant lower priority compared to local, farmer-managed seed systems in the Indian context. The reasons span ecological risk, socio-economic vulnerability, regulatory gaps, and long-term sustainability.
Ecological and biodiversity concerns:
- A review on GM crops in India warns that transgenic cultivation may lead to unintended effects on non-target organisms, gene flow into wild relatives, and loss of agro-biodiversity — especially problematic in a mega-diverse country like India. (annalsofplantsciences.com)
- Given local seeds harbour much higher genetic and ecological diversity, focusing on them helps conserve biodiversity and manage future climate and pest threats — a reserve capacity that GM monocultures may undermine.
Socio-economic vulnerability for smallholders:
- GM seeds often come with higher input costs (seed purchase, required chemicals, licensing), which places a burden on small and marginal farmers. The review of GM crops in India shows that despite some yield and pesticide-use gains, the overall benefits for all farmers have been inconsistent. (ResearchGate)
- In contrast, local seed systems allow farmers to save, reuse, and exchange seed, reducing dependency and risk.
Regulatory, safety, and long-term knowledge gaps:
- A 2025 commentary in Nature on India’s GM crop policy points out that the “necessity of GM crops in the Indian context remains contested” and that a robust national policy is still under development. (Nature)
- Given these gaps, prioritising GMOs may be premature; giving GMOs less priority allows time for strong safety, biosafety, and regulation frameworks to mature, while focusing on proven local systems.
Sustainability and long-term resilience:
- Agriculture in India faces climate volatility, soil degradation, and resource constraints. Local seed varieties — evolved under small-holder conditions with variable inputs — inherently build resilience.
- A meta-analysis of GM crop area trends shows declining adoption in India, which suggests that high-investment GM strategies may not fit all contexts. (gm.agbioinvestor.com)
- Therefore, prioritising local seeds aligns better with a sustainable, small-holder-centric agriculture model, rather than relying primarily on high-investment biotechnologies.
GM crops: documented gains — but not a panacea
Proponents of biotechnology point to meta-analyses that document average yield increases and pesticide reductions following GM adoption in many settings. For example, a widely-cited 2014 meta-analysis found GM crop adoption reduced chemical pesticide use by about 37 %, increased yields by roughly 22 %, and raised farmer profits — particularly in lower-income countries. (PMC)
Yet Indian experience shows complexity. Studies on Bt cotton — the most widely adopted GM crop in India — report clear productivity and profit gains for many farmers, but also underscore variability across regions, seasons, and farmer access to complementary inputs and markets. Economists and agronomists warn that without supportive extension services, affordable inputs, and risk-sharing mechanisms, some farmers face increased vulnerability even with higher-yielding technologies.

Seed sovereignty and farmer autonomy
A central non-technical concern is seed sovereignty — the ability of farmers to save, share, and manage their own seed supplies. Organisations such as the Food and Agriculture Organization (FAO) document how community seed systems and farmer-managed seed banks preserve diversity and give smallholders control over their cropping choices, in contrast to commercial seed models that may restrict reuse through intellectual property or hybrid/sterile seed systems. (Open Knowledge FAO)
For many advocates, seed sovereignty is a development and rights issue as much as an agronomic one.
Benefits of Microbes in Agriculture
Microbes (bacteria, fungi, actinomycetes, algae, etc.) are tiny living organisms found in soil that play a critical role in supporting crop growth, soil health, and sustainable farming. These are often harnessed as biofertilizers, biopesticides, and soil conditioners.
1. Improve Soil Fertility (Biofertilizers)
Certain microbes fix atmospheric nitrogen and convert it into forms that plants can absorb easily.
| Microbe Type | Role in Agriculture |
|---|---|
| Rhizobium | Lives in legume roots and fixes nitrogen naturally |
| Azotobacter / Azospirillum | Fix nitrogen in non-leguminous crops (wheat, maize, rice) |
| Blue-green algae & Azolla (in paddy fields) | Natural nitrogen suppliers in rice cultivation |
Reduces chemical fertilizer usage and improves soil fertility.
2. Improve Nutrient Availability
- Phosphate-solubilizing bacteria (PSB) dissolve soil phosphorus, making it available to plants.
- Potassium and zinc solubilizers make micronutrients available without chemical fertilizer use.
This means better nutrition for plants and reduced input cost for farmers.
3. Promote Plant Growth (PGPR – Plant Growth-Promoting Rhizobacteria)
Microbes produce growth-promoting substances like:
- Auxins
- Gibberellins
- Cytokinins
These improve root growth, seed germination, and crop yield.
4. Natural Disease Control (Biopesticides / Biocontrol Agents)
Some microbes protect plants from pathogens:
| Microbe | Function |
|---|---|
| Trichoderma fungus | Suppresses soil-borne diseases (root rot, wilt) |
| Bacillus thuringiensis (Bt) | Natural pest control agent used against caterpillars & bollworms |
| Pseudomonas fluorescens | Inhibits harmful fungi and bacteria |
Reduces use of chemical pesticides and supports eco-friendly farming.
5. Decompose Organic Matter & Build Soil Structure
Microbes break down organic material into humus, improving:
- Soil aeration
- Water retention
- Nutrient cycling
Soil becomes loose, fertile, and capable of storing more nutrients and water.
6. Increase Crop Yield and Quality
Microbial activity leads to:
- Bigger root systems
- More efficient nutrient uptake
- Higher crop productivity
Result: Higher yield, better grain quality, improved shelf life.
7. Reduce Environmental Pollution
Since microbes reduce the need for synthetic fertilizers and pesticides:
- Soil and water contamination is minimized
- Greenhouse gas emissions are lower
Supports sustainable and climate-resilient agriculture.
Real-World Application in India
Microbial products are used in:
- Vermicompost
- Organic manure
- Biofertilizers supplied by ICAR & state agriculture departments
Farmers using microbial inputs report lower fertilizer costs and better soil health over time.
Summary
| Benefit | Impact |
|---|---|
| Natural nutrient suppliers | Reduce chemical fertilizer needs |
| Disease & pest control | Reduce pesticide use |
| Soil building & fertility | Long-term sustainability |
| Increased yield | Higher profitability for farmers |
Microbes are the backbone of organic, natural, and regenerative agriculture.
A hybrid policy approach is recommended
Experts interviewed for this report urged a pragmatic policy mix: invest in conserving and multiplying landraces (community seed banks, incentives for millet markets), scale agro-ecological practices that reduce dependence on costly chemical inputs, and allow biotechnology where it demonstrably solves a local problem and is accompanied by farmer training, price support, and risk mitigation.
“Binary debates — desi vs biotech — miss the point,” said Dr Ramesh Iyer, a policy researcher. “India needs diverse tools: genetic diversity managed by farmers, improved varieties where appropriate, and public systems that ensure technologies serve smallholders rather than capture them.”
What farmers are already doing
Across states from Karnataka to Odisha and the Northeast, NGOs and farmer groups report renewed interest in millets and local rice varieties — driven by lower input needs, better on-farm returns per rupee invested, and growing urban demand for nutritious traditional grains. Community seed banks and farmer-led seed networks are emerging as practical infrastructure for conserving diversity and reducing dependence on external seed markets. (AESA)
Take-away
Leading scientific studies and international agencies reinforce what many farmers have known for generations: local seeds are a strategic asset for resilience, nutrition, and farmer autonomy. While GM crops have a place in improving productivity for targeted problems, India’s agricultural strategy — critics and proponents agree — should prioritise diversity, farmer control, and policies that align new technologies with the realities of smallholder agriculture.
