Crop Science & Agricultural Biodiversity: A 2025 UPSC Masterclass on India's Food Future

Crop Science and Agricultural Biodiversity represent two fundamental pillars that underpin the sustainability, resilience, and productivity of India’s vast agricultural landscape. As a nation striving to ensure food and nutritional security for over 1.4 billion people while navigating the profound impacts of climate change, the strategic management of these domains has become a critical policy imperative. Crop science, at its core, is the application of scientific principles to improve the cultivation and production of crops. It is a multidisciplinary field encompassing genetics, agronomy, soil science, and plant protection. Parallelly, agricultural biodiversity, or agrobiodiversity, refers to the variety and variability of animals, plants, and micro-organisms that are used directly or indirectly for food and agriculture. This includes the diversity of species, the genetic diversity within them, and the agro-ecosystems they form. The interplay between advancing crop science and conserving agrobiodiversity is central to building a future-proof agricultural sector, creating a complex policy arena where technological ambition often intersects with the principles of conservation and equity.

The contemporary context, particularly in 2024 and 2025, is defined by a dynamic policy environment and emerging technological frontiers. The Indian government is actively pushing for agricultural modernization through initiatives like the AgriStack and promoting new technologies, while also grappling with the complex socio-economic and ethical questions surrounding them. A landmark development has been the Biological Diversity (Amendment) Act, 2023, which has significantly reshaped the country’s biodiversity governance framework. This amendment, passed in August 2023, aims to simplify compliance, encourage investment in the AYUSH (Ayurveda, Yoga & Naturopathy, Unani, Siddha and Homoeopathy) sector, and decriminalize certain violations of the parent act. However, it has also sparked intense debate among conservationists and farmer groups who fear it may dilute the core principles of access and benefit-sharing, potentially undermining the very communities that have conserved biodiversity for generations. Simultaneously, the debate around Genetically Modified (GM) crops reached a new inflection point with the Genetic Engineering Appraisal Committee’s (GEAC) October 2022 recommendation for the environmental release of GM Mustard (DMH-11), signaling a potential shift in India’s long-held cautious stance. These recent developments form the primary lens through which we must analyze the current state and future trajectory of crop science and agrobiodiversity in India, demanding a nuanced understanding for any serious UPSC aspirant.

The Frontiers of Crop Science: From Genes to Digital Fields

Crop science is the engine of agricultural productivity, directly influencing yield, quality, and resilience. Its evolution in India reflects a journey from the Green Revolution’s focus on high-yield varieties of rice and wheat to a more nuanced, technology-driven, and sustainable paradigm that seeks to address second-generation problems like soil degradation, water scarcity, and climate vulnerability.

Plant Breeding, Genetics, and the Contentious GM Crop Debate

Plant breeding is the art and science of changing the traits of plants to produce desired characteristics. For millennia, this was accomplished through simple selection and hybridization, where farmers would save seeds from the most robust plants. Modern crop science, however, delves into the genetic code itself, offering powerful tools to accelerate and refine this process.

Genetically Modified (GM) Crops are plants whose DNA has been modified using genetic engineering methods, often by inserting a gene from another species to introduce a new trait that does not occur naturally. The two most commercially successful traits globally are herbicide tolerance (Ht) and insect resistance (Bt).

• Bt Crops: These contain a gene from the soil bacterium Bacillus thuringiensis (Bt), which produces a protein toxic to specific insect pests like the pink bollworm in cotton. Bt Cotton is the only GM crop officially approved for commercial cultivation in India, a decision made in 2002. Its adoption was rapid and widespread, and it is often credited with transforming India into a leading cotton producer by drastically increasing yields and reducing the need for chemical pesticide sprays against the bollworm complex. However, its long-term performance has been debated, with issues like the emergence of secondary pests and resistance in the pink bollworm itself becoming significant challenges.
• Ht Crops: These are engineered to tolerate specific broad-spectrum herbicides, allowing farmers to spray these chemicals to kill weeds without harming the main crop. While Ht Bt Cotton is widely grown across India, its cultivation is technically illegal as it has not received approval from the GEAC. This widespread illegal cultivation highlights a significant regulatory gap and the strong demand from some farmers for this technology.

The apex regulatory body for GM crops in India is the Genetic Engineering Appraisal Committee (GEAC), which functions under the Ministry of Environment, Forest and Climate Change (MoEFCC). The path to approval is designed to be stringent, involving multiple stages of biosafety research, including laboratory studies and confined field trials.

The debate over GM crops reached a fever pitch with the GEAC’s 2022 recommendation for the “environmental release” of Dhara Mustard Hybrid-11 (DMH-11). This transgenic mustard hybrid, developed by the Centre for Genetic Manipulation of Crop Plants at Delhi University, was created using a bacterial genetics system known as barnase/barstar technology. This system facilitates cross-pollination and hybridization in mustard, which is largely a self-pollinating plant, thereby enabling the development of higher-yielding hybrids. Proponents, including many scientists and government bodies, argue that GM mustard is a critical tool to boost domestic edible oil production and reduce India’s massive import bill, which exceeds $15 billion annually. They point to extensive safety assessments showing it is safe for consumption and the environment.

However, opponents, including a coalition of farmers’ unions, environmental activists, and consumer groups, have raised serious objections. Their concerns are multifaceted: the potential for the herbicide tolerance gene (the ‘bar’ gene) to encourage increased herbicide use, leading to negative environmental consequences and the emergence of superweeds; the potential adverse impact on honey bee populations, which are vital for pollination; and the socio-economic implications of increased corporate control over the seed supply. In response to legal challenges, the Supreme Court in late 2023 and early 2024 has been hearing arguments, effectively placing a temporary hold on its commercialization and emphasizing the need for a thorough, unbiased examination of all available data before a final decision is made. As of mid-2025, the fate of DMH-11 remains undecided, symbolizing the deep divisions in Indian society and policymaking on the role of genetic engineering in agriculture.

Fun Fact: The Bacillus thuringiensis (Bt) bacterium, the source of the insect-resistance gene in Bt crops, is a naturally occurring soil microbe that has been used as an organic pesticide spray by farmers for decades. Genetic engineering simply took the gene responsible for producing the insecticidal protein and placed it directly into the plant’s own DNA.

Agronomy and the Push for Sustainable Practices

Agronomy is the science of soil management and crop production. The intensive agricultural practices of the Green Revolution, while successful in averting famine, led to significant environmental degradation, including soil salinization, depleted groundwater tables, and loss of soil organic matter. Recognizing this, the policy focus has been gradually shifting towards more sustainable models.

• Soil Health Card Scheme: Launched in 2015, this ambitious scheme aims to provide every farmer with a customized “health card” for their land. These cards detail the soil’s nutrient status (macro and micro-nutrients) and offer specific recommendations on the appropriate dosage of fertilizers and soil amendments. The goal is to move away from the indiscriminate use of urea towards more balanced and efficient nutrient management, thereby improving soil health and reducing input costs for farmers.
• Bharatiya Prakritik Krishi Paddhati (BPKP): This is a government-promoted program to encourage chemical-free, traditional farming methods. It subsumes concepts like Zero-Budget Natural Farming (ZBNF), which was pioneered by Subhash Palekar. This method emphasizes the use of on-farm, cow-dung-based bio-inputs like Jeevamrutha (a fermented microbial culture) and Beejamrutha (a seed treatment). The philosophy is to restore the natural ecosystem of the soil, eliminating the need for external chemical inputs. The government is promoting BPKP as a key strategy for making farming more climate-resilient and doubling farmers’ incomes.
• Precision Agriculture: This represents the high-tech frontier of agronomy. It involves using advanced technologies like GPS, remote sensing, drones, and the Internet of Things (IoT) to monitor and manage crop fields with a high degree of spatial and temporal precision. For example, drones equipped with multispectral sensors can identify patches of a field suffering from nutrient deficiency or pest attack, allowing for the targeted application of fertilizers or pesticides. This “more crop per drop” approach optimizes the use of inputs, leading to significant savings in water, fertilizer, and pesticides, while also minimizing environmental runoff.

Plant Protection: An Evolving Battlefield Against Pests and Diseases

Protecting crops from pests and diseases is a perennial challenge. The over-reliance on chemical pesticides has led to numerous problems, including pest resistance, destruction of beneficial insects, pesticide residues in food, and severe environmental pollution. The modern approach is Integrated Pest Management (IPM). IPM is not a single method but a holistic, ecosystem-based strategy that prioritizes long-term prevention. It combines a hierarchy of control methods:

1. Cultural Controls: Practices like crop rotation, adjusting planting times, and maintaining field sanitation to disrupt pest life cycles.
2. Mechanical/Physical Controls: Using traps, barriers, or manual removal of pests.
3. Biological Controls: Introducing or encouraging natural enemies of pests, such as predators (e.g., ladybugs) and parasitoids.
4. Chemical Controls: Using pesticides, but only as a last resort, and selecting the most specific and least disruptive ones.

The government promotes IPM through various schemes and has established Central Integrated Pest Management Centres across the country. A significant recent development in this area was the Ministry of Agriculture and Farmers’ Welfare’s 2022 notification restricting the use of the herbicide glyphosate to be applied only through Pest Control Operators. This move aims to curb its widespread and often unsafe use by untrained individuals, reflecting a growing regulatory concern over the health and environmental impacts of chemical pesticides.

Agricultural Biodiversity: The Foundation of Resilience

Agrobiodiversity is the bedrock upon which sustainable agriculture is built. It encompasses the genetic resources for food and agriculture, including traditional crop varieties (landraces), wild relatives of crops, and diverse livestock breeds. This diversity is crucial for developing new crop varieties that can withstand pests, diseases, and climate change. India is one of the world’s 17 megadiverse countries and a recognized center of crop diversity, being the origin of crops like rice, mango, and eggplant.

Captivating Statistic: According to the Food and Agriculture Organization (FAO), about 75% of the world’s plant genetic diversity has been lost since the 1900s as farmers worldwide have shifted to genetically uniform, high-yielding varieties. This genetic erosion makes our food systems more vulnerable to shocks.

India’s Legal & Policy Framework for Biodiversity

India has a robust legal framework to govern its biological resources, primarily anchored by two key legislations that are crucial for the UPSC syllabus.

1. The Biological Diversity Act, 2002, and its 2023 Amendment

The Biological Diversity Act, 2002 was enacted to give effect to the principles of the United Nations Convention on Biological Diversity (CBD), to which India is a signatory. Its primary objectives are:

• Conservation of biological diversity.
• Sustainable use of its components.
• Fair and equitable sharing of benefits arising out of the use of biological resources, known as Access and Benefit-Sharing (ABS).

The Act established a three-tiered structure for its implementation: the National Biodiversity Authority (NBA) at the national level, State Biodiversity Boards (SBBs) at the state level, and Biodiversity Management Committees (BMCs) at the local body level. A key feature of the Act was that any entity seeking to access Indian biological resources or associated traditional knowledge for research or commercial purposes had to seek prior approval from the NBA and sign a benefit-sharing agreement.

In August 2023, the Indian Parliament passed the Biological Diversity (Amendment) Act, 2023, which introduced sweeping changes to this framework. The government’s stated rationale was to simplify, streamline, and decriminalize the compliance process to encourage more investment, particularly in the AYUSH sector.

Key Changes in the 2023 Amendment:

• Exemptions for AYUSH: The amendment exempts registered AYUSH practitioners and users of “codified traditional knowledge” from the requirement of seeking prior approval from biodiversity boards for accessing biological resources.
• Decriminalization: It removes criminal penalties for violations and replaces them with monetary penalties, to be determined by an adjudicating officer.
• Focus on “Indian Companies”: It encourages foreign investment by clarifying the definition of a foreign-controlled company and allowing them to access resources, provided they are registered in India and comply with certain conditions.
• Narrowing the Scope of ABS: The benefit-sharing obligation is now primarily linked to the commercial utilization of the resource, potentially excluding intermediate steps like research and bio-survey.

This amendment has been met with fierce criticism from a wide range of stakeholders. Conservationists and legal experts argue that it fundamentally dilutes the spirit of the original Act. They contend that exempting the entire AYUSH industry—a multi-billion dollar sector—from the ABS framework undermines the rights of the local communities who are the traditional custodians of this knowledge and these resources. The decriminalization of offenses is seen as weakening the deterrent effect against biopiracy. Critics fear that these changes prioritize corporate interests and “ease of doing business” over the core principles of conservation and equity enshrined in the CBD. The government, in its defense, has argued that the changes will foster a more conducive environment for research and development, ultimately leading to better utilization of India’s biological wealth for public good, without compromising the rights of communities.

2. The Protection of Plant Varieties and Farmers’ Rights (PPV&FR) Act, 2001

This is a unique piece of legislation that attempts to balance the rights of plant breeders with those of farmers. It was enacted to comply with India’s obligations under the WTO’s TRIPS agreement, which requires member countries to provide some form of intellectual property protection for plant varieties. Instead of adopting the stringent patent-like system prevalent in many Western countries (UPOV model), India opted for a ‘sui generis’ (of its own kind) system.

The PPV&FR Act grants Plant Breeders’ Rights (PBRs), which give the breeder exclusive rights to produce, sell, market, distribute, import, or export the protected variety. However, it simultaneously recognizes and protects the rights of farmers in an unprecedented manner.

Key Farmers’ Rights under the PPV&FR Act, 2001:

• Right to Save, Use, Sow, Re-sow, Exchange, or Share: Farmers are explicitly allowed to save seeds from a protected variety and use them in subsequent seasons on their own farm. They can also exchange or share these seeds with other farmers.
• Right to Sell Seed: Farmers can also sell their farm produce, including seed, of a protected variety, with one condition: they cannot sell it as “branded seed.” This means they can sell it in an unbranded manner, protecting their traditional practices.
• Right to Benefit Sharing: Farmers and communities who have contributed to the development of a new variety are entitled to a share of the benefits arising from its commercialization.
• Right to Compensation: If a protected variety fails to provide the expected performance under recommended conditions, farmers can claim compensation from the breeder.
• Right to Protection from Infringement: Farmers are protected from legal action if they unknowingly infringe on a breeder’s right.

To remember the core rights of farmers under this act, you can use the following mnemonic:

Mnemonic: “Farmers can SURELY SELL their seeds.”

• Save, Use, Re-sow, Exchange, Liability (Compensation), Yield (Sell).

The table below contrasts the rights under the PPV&FR Act with a standard patent regime.

Intersecting Challenges and Future Directions

The domains of crop science and agrobiodiversity are being shaped by overarching global challenges, most notably climate change and the digital revolution.

Climate Change and the Imperative for Climate-Resilient Agriculture (CRA)

Climate change is no longer a future threat but a present reality for Indian farmers. Increased frequency of extreme weather events like droughts, floods, and heatwaves, coupled with shifting monsoon patterns, is wreaking havoc on crop cycles and yields. The Economic Survey 2017-18 had estimated that climate change could reduce farm incomes by up to 25% in the medium term. This necessitates a paradigm shift towards Climate-Resilient Agriculture (CRA). CRA is an approach that involves developing and promoting agricultural practices and crop varieties that can better withstand climate shocks. Key components include:

• Development of Climate-Smart Varieties: The Indian Council of Agricultural Research (ICAR) and other institutions are actively working on breeding crop varieties that are tolerant to drought, flooding, and high temperatures. For example, drought-tolerant rice varieties like Sahbhagi Dhan have been developed.
• Water Management: Promoting micro-irrigation techniques like drip and sprinkler systems to improve water-use efficiency.
• Agroforestry: Integrating trees with crops and livestock to create more resilient and diversified farming systems.
• Weather Forecasting: Leveraging technology to provide farmers with more accurate and timely weather advisories.

Digital Agriculture: Promise and Perils

The government is aggressively promoting the digitization of the agricultural sector. The most ambitious and controversial of these initiatives is the AgriStack. AgriStack aims to create a unified digital database of India’s farmers, linking their identity (Aadhaar) with their land records and other information. The stated goal is to create a platform for delivering targeted services, credit, and subsidies. Another recent initiative is KISAN-e, a platform leveraging AI for crop assessment and advisory services.

While these digital initiatives hold the promise of transforming Indian agriculture by improving efficiency and transparency, they are also fraught with challenges.

• Data Privacy and Security: The creation of a massive, centralized database of farmers’ personal and land data raises significant concerns about privacy, data security, and the potential for misuse by private corporations.
• The Digital Divide: A large proportion of Indian farmers, particularly small and marginal ones, lack access to smartphones and digital literacy, which could lead to their exclusion from the benefits of these platforms.
• Monopolization by Agribusiness: There are fears that AgriStack could facilitate the takeover of the agricultural data ecosystem by large tech and agribusiness companies, potentially leading to the exploitation of farmers.

Critical Policy Appraisal

Analytical Lens: UPSC Focus (Mains & Prelims)

Conceptual Basis

The legal and ethical framework for crop science and agricultural biodiversity in India is primarily built upon two landmark pieces of legislation:

1. The Biological Diversity Act, 2002: Enacted to fulfill India’s commitments under the Convention on Biological Diversity (CBD), it establishes the legal basis for conservation, sustainable use, and, most importantly, Access and Benefit-Sharing (ABS).
2. The Protection of Plant Varieties and Farmers’ Rights (PPV&FR) Act, 2001: A ‘sui generis’ law that operationalizes India’s obligations under the TRIPS agreement while creating a unique balance between the intellectual property rights of plant breeders and the traditional rights of farmers.

UPSC Integration: Connecting the Dots

• GS Paper 3 (Economy & Environment): This topic is a direct fit. It connects to Agriculture (cropping patterns, farm subsidies, technology in aid of farmers), Food Security, Conservation, and Environmental Impact Assessment. The GM crop debate is a classic example of the technology-environment conflict. The economic angle involves analyzing the impact of these policies on farmers’ income and India’s import-export balance (e.g., edible oils).
• GS Paper 2 (Polity & Governance): The legislative process behind the Biological Diversity (Amendment) Act, 2023 is a case study in governance, stakeholder consultation (or lack thereof), and the functioning of parliamentary committees. The roles of regulatory bodies like the GEAC and the National Biodiversity Authority are key aspects of the governance structure.
• GS Paper 4 (Ethics): The GM crop debate and the changes to the biodiversity law are rife with ethical dilemmas. These include corporate greed vs. public good, inter-generational equity (conserving biodiversity for the future), and the rights of indigenous communities vs. national economic interests.

Future Impact & Policy Relevance

The current policy trajectory indicates a strong governmental push towards technological solutions (GM crops, digital agriculture) and a simplification of regulatory frameworks to attract private investment. The long-term impact will depend on the ability to balance these objectives with the principles of equity, sustainability, and conservation. The implementation of the 2023 Biodiversity Amendment will be a critical test of whether “ease of doing business” can coexist with fair benefit-sharing. The final decision on GM Mustard will set a precedent for the role of genetic engineering in India’s food future. The key policy challenge moving forward will be to ensure that technological advancements do not come at the cost of farmer autonomy, environmental health, and the rich agrobiodiversity that forms the very foundation of our agricultural resilience.

Prelims Practice Question (MCQ)

Question: With reference to the Protection of Plant Varieties and Farmers’ Rights (PPV&FR) Act, 2001, which of the following rights is granted to farmers?

1. The right to sell seeds of a protected variety under their own brand name.
2. The right to claim compensation from the breeder if a protected variety underperforms.
3. An absolute right to use a protected variety for commercial seed production without any restrictions.
4. The right to export seeds of a protected variety for commercial purposes.

Answer: 2 Explanation: The PPV&FR Act, 2001, grants several unique rights to farmers. Option 2 is correct as Section 39(2) of the Act allows farmers to claim compensation if a registered variety fails to provide the expected performance under given conditions. Option 1 is incorrect because while farmers can sell the seed, they cannot sell it as “branded seed.” Option 3 is incorrect as the right is for saving, sowing, and re-sowing on their own farm, not for unrestricted commercial production. Option 4 is incorrect as the commercial rights, including export, are reserved for the breeder.
