Biotechnology refers to any technique that utilises living organisms or substances derived from them to create or modify products for practical applications. According to the Food and Agriculture Organisation (FAO), agricultural biotechnology encompasses a variety of tools that scientists use to understand and manipulate the genetic makeup of organisms for the production or processing of agricultural products.
This technology addresses challenges throughout agricultural production and processing. It is employed in plant breeding to enhance and stabilise yields, improve resistance to pests, diseases, and abiotic stresses such as drought and cold, and enrich the nutritional content of foods. Furthermore, biotechnology plays a crucial role in disease diagnostics and in the production of vaccines for animal diseases.
Many argue that biotechnology in agriculture is more effective than the use of agrochemicals, which are often associated with environmental damage and can be impractical for farmers. However, the primary ethical dilemma surrounding biotechnology in agriculture lies in balancing the potential benefits such as increased crop yields and improved food quality against the risks.
The purpose of this article is to explore the balance between the potential benefits of biotechnology in agriculture and the ethical considerations related to safety, public health, and environmental integrity.
The Importance of Biotechnology in Agriculture
Agriculture is a sector closely linked to biotechnology. From the earliest days, farmers have manipulated plants and animals through selective breeding and planting. They have chosen specimens with desirable traits, leading to the creation of new varieties and species.
In recent times, agricultural biotechnology has emerged, thanks to the technological advancements of the 20th century. This field focuses on using biological tools and techniques involving living organisms to enhance agriculture, leading to the development of improved agricultural products.

Over the years, biotechnology has facilitated significant advancements in the agricultural sector. Some key improvements include:
A. Increased Production
Biotechnology can be employed in various ways to achieve higher yields. For instance, it can enhance flowering capacity, increase photosynthesis, or improve the uptake of nutrients. In the long term, genetic engineering can further boost the production of valuable components in specific crops. For example, cassava and rice are essential calorie sources for millions of people, yet both staples have low protein content. For those with limited access to a varied diet, this can result in unbalanced nutrition. Genetic engineering can modify the amino acid composition of plant proteins, increasing the nutritional value of these staple crops.
B. Reduced Use of Agrochemicals
Biotechnology can help diminish the reliance on agrochemicals, which small farmers in developing countries often cannot afford. For example, nitrogen-fixing bacteria which are popularly used to inoculate soil, reduces the need for expensive fertilisers that can heavily burden the limited foreign exchange resources of rural farmers. Additionally, a reduction in agrochemical use results in fewer residues in final products.
C. Increased Nutritional Value
Biotechnology has enabled farmers to produce crops with higher nutritional value, improved flavour, and better texture. For instance, biotechnology in agriculture has made it possible to cultivate soybeans with higher protein content, beans with more amino acids, and starch-rich potatoes. It also enhances the taste and flavour of crops by stimulating the activity of enzymes present in plants, helping maintain freshness for a longer duration.
D. Disease Resistance
Farmers often rely on insecticides to manage viral infections spread by insects which is harmful to the environment in the long run. Fortunately, genetically modified plants are less susceptible to viral infections, making it easier for farmers to manage crop damage without relying on chemicals which are detrimental to soil health.
Ethical Issues in Biotechnology Advancements in Agriculture
Agricultural Biotechnology, particularly the creation of genetically modified (GM) crops, has sparked controversy for several reasons. Some of these reasons include:
The Environmental Issue
One ethical dilemma centres on the environment. Supporters of agricultural biotechnology argue that it can help farmers cut back on chemicals that negatively affect the ecosystem, suggesting that biotechnology is beneficial. However, critics contend that there is insufficient knowledge about the long-term environmental impacts of genetically engineered crops, beneficial insects, and microorganisms, leading them to believe that the use of biotech products should be avoided for now.
According to these critics of biotechnology in agriculture, we have an ethical duty to future generations to ensure that biotech products do not harm the environment and if there is no concrete proof to determine long-term safety, biotech products must be stopped. In contrast, proponents believe that scientific evaluations can demonstrate that genetically engineered products are safe for the environment.
The Food Safety Issue
Another ethical concern revolves around the safety of genetically engineered foods for consumption. Most individuals agree that it is ethically wrong to endanger people if there is even the slightest chance that biotech products could be harmful to humans, yet advocates of biotechnology maintain that biotech foods do not pose risks to consumers. Conversely, critics argue that food safety tests conducted on biotech foods are inadequate, biased, or simply inappropriate. Again, the dispute is not about whether biotechnology in agriculture is something we should pursue but rather whether we can definitively claim that biotech foods are safe. If we cannot make that claim, then these products should not be permitted in the marketplace.
Playing God
Genetic modification is perceived as human interference in creation, thus being an unnatural act. Often framed as a religious issue, it posits that this technology is “so intrusive to life processes that they amount to a form of disrespect for humanity’s proper relationship to nature, a form of playing God”. Certain religions attribute a specific “essence” to each living organism, linking the concept of genes to the idea of essence. Others argue that biotechnology disrupts natural order and breaches the ethical boundaries of what humans are allowed to do. Alternatively, some believe that science and progress are inherently positive and represent God-given abilities that enable humanity to sustain life and manage the environment more effectively.
Distribution of Benefits and Burdens
Another critical issue, especially in developing nations, is the principle of equitable distribution. This raises questions about whether the outputs generated by biotechnology in agriculture will adequately serve those in need and whether they will contribute to overall societal wealth. This includes claims that innovations arising from modern biotechnology are being introduced by private enterprises with a profit motive. Additionally, it is worth discussing whether technology can enhance technical employment while simultaneously displacing subsistence labour due to the replacement of traditional practices.
Balancing Innovation and Safety in Agricultural Ethics
The term “ethics” encompasses the ideals, values, and standards that individuals employ to assess their actions as either good or bad. These ethical principles create a societal framework that allows for the evaluation of whether a specific issue or action is deemed acceptable and justifiable. Furthermore, ethics play a vital role in defining concepts of responsibility and justice within society. In the context of agricultural biotechnology, particularly genetically modified organisms (GMOs), there exists a pressing need to balance the innovative potential of these technologies with the paramount importance of safety. To achieve this balance, several ethical guidelines and regulatory frameworks have been established.
A. The European Union Regulatory Framework
The European Union (EU) has developed a comprehensive legal framework designed to ensure that the advancement of modern biotechnology, especially GMOs, takes place under stringent safety measures. This regulatory framework is multifaceted and aims to achieve several crucial objectives:
1. Protection of Human and Animal Health and the Environment: The EU prioritises the safeguarding of human and animal health alongside environmental protection. This is accomplished through rigorous safety assessments that adhere to the highest possible standards. Such assessments are conducted at the EU level before any GMO can be approved for market introduction, ensuring a thorough evaluation of potential risks.
2. Harmonised Risk Assessment Procedures: The EU framework includes the implementation of unified procedures for the risk assessment and authorisation of GMOs. These procedures are designed to be efficient, time-bound, and transparent, allowing for a quicker response to innovations while maintaining safety standards. This harmonisation helps create consistency across member states, promoting a collaborative approach to regulation.
3. Clear Labelling Practices: One of the essential aspects of the EU’s approach is the mandate for clear labelling of GMOs available in the market. This requirement enables consumers, farmers, and food chain operators to make informed choices based on their preferences regarding genetically modified products. The availability of transparent information empowers stakeholders and fosters trust in the biotechnology sector.
4. Traceability of GMOs: The EU also emphasizes the importance of traceability once GMOs enter the market. This means that all GMOs must be tracked from their point of origin through distribution and sale. Traceability not only enhances consumer confidence but also facilitates effective monitoring and accountability.
By adopting stricter safety protocols and comprehensive risk assessment procedures, the EU aims to fortify both innovation and safety within the realm of agricultural biotechnology.
B. Effectively Communicating Biotechnology to the Public
In an era where the public increasingly seeks to understand the science behind agricultural practices, effective communication has become paramount. Scientists and plant biotechnologists must bear the responsibility of adequately conveying complex research and its implications to the public in an engaging and accessible manner.
1. Addressing Biosafety and Beyond: Communication efforts must not solely focus on biosafety concerns but also encompass a broader range of complex and often contentious issues related to agricultural biotechnology. These include social, ethical, political, and economic considerations that influence public perception and acceptance of GMOs.
2. Building Public Trust: Effective communication is crucial for building and maintaining public trust in agricultural biotechnology. By being transparent and addressing concerns openly, scientists can help demystify biotechnology and illustrate its potential benefits, ultimately enhancing public understanding and acceptance.
3. Utilising Innovative Communication Strategies: Scientists are encouraged to adopt innovative and engaging strategies for conveying their messages, such as utilising social media, visual aids, and interactive platforms. These methods can make complex information more relatable and easier to comprehend for diverse audiences.
C. Ethical Guidelines for Research and Development
Establishing ethical standards for the development and testing of new agricultural biotechnologies is crucial. Some of these guidelines include:
1. Beneficence(Promoting Well-Being) and Non-maleficence(Avoiding harm):
In the context of biotechnology in agriculture, it is imperative to prioritise the ethical principle of beneficence, which emphasises the importance of ensuring that all biotechnological products provide significant benefits to human health, promote the quality of soil, and contribute positively to the overall well-being of our planet. This means that scientists and researchers should focus on developing biotechnological innovations that not only enhance agricultural practices but also nurture ecosystems and support sustainable environmental practices.
Equally important is the principle of non-maleficence, which dictates that these biotechnological advancements must be designed and implemented in such a way that they do not pose any harm to humans or the environment.By adhering to these foundational principles, the field of biotechnology can ensure that its contributions lead to a healthier, safer, and more sustainable world for all living beings.
2. Justice and Fairness: Ethical decision-making in biotechnology should uphold principles of justice and fairness, ensuring the equitable distribution of benefits and burdens across diverse populations. This includes addressing disparities in access to biotechnological innovations and promoting global collaboration in research and development.
3. Accountability and Transparency: Stakeholders in biotechnology, including scientists, policymakers, and industry leaders, should embody principles of accountability and transparency. This involves disclosing potential conflicts of interest, sharing research findings openly, and engaging with the public to build trust and understanding.
Case Studies of Biotechnology in Agriculture
1. Improving Plant Growth and Resistance
Improving plant growth and resistance to diseases serves as an important example of biotechnology in agriculture. Since the dawn of agriculture, farmers have been selectively breeding plants to obtain desirable traits, such as larger fruit size, more vigorous plant growth, or disease resistance. This traditional method of cross-breeding involves farmers selecting the best examples from each generation for further breeding, a process that requires many generations of experimentation to achieve the desired results.
Case Study: Enhancing Banana Production in Sri Lanka Using Tissue Culture and Mutation Induction
Bananas rank as the fourth most important food crop globally in terms of production value, providing sustenance for hundreds of millions of people in tropical and subtropical regions, as well as being utilised for medicinal and industrial purposes. In Sri Lanka, banana farming is on the rise, with 55 locally cultivated varieties. However, many of these varieties are susceptible to disease.
The Department of Botany at the University of Colombo has partnered with the FAO and the International Atomic Energy Agency (IAEA) on several projects. One significant approach involves using irradiation to create mutant banana lines, thereby increasing genetic variation and producing new varieties. Biotechnology also plays a role in disease detection among these new varieties. Furthermore, tissue culture techniques are being employed to help farmers improve banana production and reduce disease incidence. As a result, virus-free mutant banana plants are being produced for rural farmers in Sri Lanka.
2. Improving Animal Health and Breeding
Biotechnology also significantly contributes to enhancing animal health and breeding. In livestock production, biotechnology enables animals to grow faster while consuming less food, resulting in better meat quality. Cloning techniques can also be applied, and animals resistant to diseases can be bred through these methods. By implementing biotechnology solutions, farmers can boost their production and enhance the quality of animal products.
Case Study: Breeding for Increased Sheep Productivity in India Using DNA Testing for High Fertility
Sheep-rearing serves as a vital source of income in drought-prone rural areas of India. In Maharashtra’s Deccan plateau, Deccani sheep keepers depend heavily on lamb sales for their livelihood.
In a project by the Nimbkar Agricultural Research Institute (NARI), a gene that enhances ewe fertility was introduced by crossbreeding Deccani sheep with the prolific Garole sheep breed. This led to the development of more productive ewes that retain the desirable traits of Deccani sheep, such as larger body size and hardiness.
DNA testing using polymerase chain reaction (PCR) was employed to detect the presence of the high-fertility gene during the breeding program. This method made it quick and easy to determine whether a lamb carried the favourable gene, thus speeding up the selection of productive ewes. As a result of this breeding program, the average productivity of these sheep has increased by up to 50 percent due to a higher number of lambs per lambing. The new sheep have been successfully introduced into local flocks, thereby enhancing the income of local farmers.
3. Improved Plant Varieties
It is essential to highlight the advances in seed quality enabled by biotechnology in agriculture. Biotechnology has provided more effective and efficient methods to enhance the crops that sustain our population while ensuring high-quality seeds at harvest time. Seed quality has always been fundamental to successful farming, and biotechnology has improved seeds in several ways.
Case Study: Producing New Crop Varieties Using Mutation Breeding
Mutagenesis, which involves altering the genetic material of an organism (for example, using radiation), has been used to develop new crop varieties, particularly in developing countries. For instance, mutation-bred rice varieties in Thailand and Myanmar, along with pearl millet in India, are widely grown. In the Mekong Delta region of Vietnam, three varieties of rice with improved food quality and salt tolerance have been released, increasing annual smallholder incomes in the region.
Call for Responsible Innovation
The urgent requirement for a responsible and thoughtful approach to biotechnology has never been more critical. It is essential to ensure that advancements in agricultural innovations are not only effective in enhancing productivity but also adhere to stringent ethical regulations. Furthermore, these innovations must prioritise public health, safeguarding consumers and communities from potential risks associated with biotechnological interventions. Additionally, environmental sustainability must be at the forefront of these developments, ensuring that they support biodiversity, soil health, and ecosystem balance. By aligning agricultural biotechnology with these crucial standards, we can foster a safer and more sustainable future for both agriculture and society as a whole.
