New Genomic Techniques Essential for Agriculture Amid Rising Temperatures
As Europe contended with extreme heat and droughts this summer, its agricultural sector faced significant challenges, particularly in key food-producing regions. The harsh weather has led to concerns over food supply, prompting discussions about the future of agricultural practices and the adoption of biotechnology.
In Spain’s Valencian Community, the ongoing drought is predicted to yield the lowest wine grape harvest in three decades. Similarly, rural areas in Greece are experiencing water rationing that has diminished the yields of crops such as peaches, nectarines, and plums. Italy’s grape harvest has been affected by unpredictable weather, with regions like Sicily suffering from drought while Tuscany and Lombardy contend with flooding. Switzerland has also reported severe losses in wheat and potato harvests due to prolonged rain.
The conversation surrounding agricultural resilience often revolves around sustainable practices and the potential of New Genomic Techniques (NGTs) to combat the effects of climate change on food production. These technologies promise a new era in crop development, although their implementation faces hurdles related to environmental impact, health concerns, and ethical considerations.
Selective breeding has been utilized for centuries to cultivate crops with desirable traits; however, traditional methods can be slow and imprecise. In the 1970s, scientists made strides in genetic engineering, allowing for quicker modifications. This was followed by the introduction of genetically modified organisms (GMOs), which involve the transfer of genes from one species to another to enhance certain traits, such as pest resistance.
Gene editing techniques like CRISPR/Cas9, developed in 2012, represent a significant advancement, allowing for precise modifications of a plant’s genetic code without incorporating foreign DNA. Approval for various gene-edited crops has been granted in countries such as the United States and Japan, signaling a growing acceptance of these methods.
However, in the European Union, strict regulations under the 2001 GMO Directive currently hinder the production of plants using NGTs. This regulation stems from the EU’s commitment to limiting transgenic crops. In a ruling from the European Court of Justice in 2018, it was decided that gene-edited plants should still be regulated as GMOs, sparking criticism from scientists and agricultural stakeholders who argue for more flexible policies.
In July 2023, the European Commission proposed a new regulation that would create two categories of plants modified by NGTs: one comparable to conventional crops, which would bypass GMO labeling requirements, and another requiring stricter assessments. The European Parliament later supported these new rules in February 2024, emphasizing the importance of transparency and advocating for the elimination of patents on NGT plants.
Despite the potential benefits of genetically modified and gene-edited crops in increasing yields and addressing food security, there remain significant concerns regarding health risks, environmental impact, and the concentration of power within the global seed market. Critics warn that these advancements may benefit large corporations at the expense of small farmers and organic producers.
As the regulatory landscape evolves, the path toward embracing new agricultural technologies will require careful consideration of ethical and environmental implications, ensuring that innovations can sustainably support food security in Europe while protecting biodiversity and small-scale agriculture.
