Introduction:
For nearly 25 years now, plants that have undergone biotechnological cultivation have been grown all over the world. The enormous advantages of biotechnology in agriculture are supported by numerous publications. The ecosystem, climate, and farmer yields are all benefited by the cultivation of these plants.
Plant types created by biotechnology have been used in agriculture since 1996. 13 percent of the world's arable land is currently being used to cultivate biotech cultivars, with soybeans, maize, cotton, and rapeseed accounting for the majority of those acres.
In multiple articles in specialised journals, the British agricultural economist Graham Brookes has evaluated the economic and ecological effects of agriculture between 1996 and 2020.
Higher Yields: His research provides a crystal-clear picture. Growing genetically modified cultivars results in noticeably increased yields and, consequently, higher agricultural incomes. One billion tonnes of additional food, feed, and fibre crops were produced over the time period under study. The average yield of insect-resistant maize was 17% higher than that of regular plants. The same is true with cotton, which was genetically modified to resist some dangerous insects. On average, yields grew by 14.5 percent.
Less Need for Pesticides: Biotechnology does not just result in increased yields. Farmers have also used fewer insecticides as a result of plants that are resistant to hazardous insects. A total of 7.5 million tonnes of pesticides could be discarded between 1996 and 2022. This is equivalent to 1.5 times what China uses yearly. In areas where biotech varieties were planted, pesticide use dropped by 7.2% on average. Cotton and maize received 30 and 41% fewer pesticide applications, respectively.
Lower CO2 emissions: Growing genetically modified plants also reduces carbon dioxide emissions. Less frequent tractor use is necessary in the fields since the plants are more pest-resistant. This lowers CO2 emissions and conserves diesel. Additionally, cultivating cultivars that are resistant to specific herbicides enables more humane weed control. Because of the usage of herbicides, the soil requires less plough time and can bind more carbon. No-till farming techniques have allowed for the transition of many farmers. Such cultivation techniques reduced CO2 emissions by 23.6 million kilogrammes in 2020, or almost 15 million cars' annual emissions.
Reduced need for land: Biotechnology has also helped with better land management. Biotech cultivars need less land because they provide yields that are much higher than those produced by traditional farming techniques. Without the use of biotechnology, an additional 234,000 square kilometres of cultivated area would be required to maintain current levels of soybean, corn, cotton and rapeseed yields worldwide. This is equivalent to Switzerland's size by about six times.
Conclusion:
Small-scale farmers can also greatly profit from biotechnology. Contrary to what many people think, biotechnology can help small farmers protect their crops. For instance, as demonstrated in Bangladesh, the adoption of genetically modified eggplants has significantly reduced the need for insecticides, increased yields, and significantly increased farmer income. Specifically, the aubergine has been genetically modified with Bt (Bacillus thurigiensis), a pesticide that is allowed in organic farming and that gives the plant the ability to fight itself. Researchers from ETH and other institutions have discovered the gene that protects cassava from the terrible mosaic disease. This essential staple item, which is mostly grown by small farmers in Africa and Southeast Asia, could be shielded from viral illness by genome editing.
