Summary
A Nature editorial argues that crop biotechnology could help limit agriculture’s contribution to climate change and biodiversity loss. It points to gene editing, crop-trait discovery and research on lower-methane rice, while stressing the need for safeguards and public readiness.
A Nature editorial published on 11 November argues that biotechnology could help reduce the climate and biodiversity impacts of food production. It highlights gene editing, the search for useful traits in plant genomes and research on rice emissions as possible ways to produce food while limiting pressure to expand farmland.
The editorial presents these approaches as potential contributions, not a single solution. Their value would depend on how they perform in farming and whether governments, regulators, researchers, companies and farmers can put them into practice with appropriate safeguards.
Why land use is central to the case
The editorial says cultivated land grew by roughly eight million hectares a year between 2015 and 2024. It also describes land clearance and land-use change as contributing up to five billion tonnes of carbon annually and as a major cause of biodiversity loss. Producing enough food within the existing agricultural footprint could therefore help address both problems.
The proposed route is to develop crops that yield more or better withstand heat, drought and disease. If those traits help maintain food production without further land conversion, they could reduce pressure on habitats. That outcome is a potential benefit, rather than an automatic result of using biotechnology.
The editorial cites a Perspective by bioengineers Shekhar Mishra, Lauren Lui and Adam Arkin, who describe 77 technologies with applications across agriculture, aquaculture and other sectors. The editorial says many are ready for large-scale field testing. It also notes that Argentina, China and the United States have given the green light to engineered drought-tolerant crops.
Rice is another potential target. Rice farming produces around 9% of human-caused emissions of methane, according to the editorial, which reports that researchers have found a way to reduce those emissions. It does not describe the method or quantify the reduction, so the finding is best understood here as a research direction rather than a specified climate benefit.
From crop traits to deployment
Gene editing changes an organism’s genes precisely to produce particular traits. Germplasm mining takes a different route: researchers analyse large libraries of plant-genome sequences to identify traits that could be useful in crop improvement. Both approaches aim to give breeders ways to develop plants suited to environmental stresses or farming needs.
The editorial contrasts the current interest in these methods with the stalled ambitions for agricultural biotechnology in the 1990s. Public concern about eating transgenic crops, insufficient study of health and environmental risks, and worries about corporate control all shaped resistance. It argues that these concerns make public trust and careful regulation part of deployment, not an afterthought.
Regulatory approaches have since shifted in some places. The editorial says the European Union amended its genetic-modification regulations in June to permit cultivation of some gene-edited crops. It argues that biotechnology could complement other approaches to farming if implemented wisely, safely and ethically. The central test is whether improvements in crop production can help meet food needs while reducing, rather than shifting, pressure on land and ecosystems.
