After fifteen years of commercial cultivation, a substantial body of literature now exists addressing the potential impacts of GM crops on the environment. This review takes a biodiversity lens to this literature, considering the impacts at three levels: the crop, farm and landscape scales.

The potential impact of GMOs on biodiversity is a complex topic of great interest, particularly in relation to biological conservation and ecosystem resilience. While there is now an increasing amount of literature on the possible environmental implications of GM plants on biodiversity at different trophic levels, it is essential to first define bi...
With the rise in GM crop production and area under GM crop cultivation in the last 24 years, the debate on the risks associated with GM crop cultivation has also intensified, with more and more studies being published both in support of and against GM crops (Prakash et al. 2011). GM plants increase the crop’s genetic diversity when considered in th...
Intensive agriculture is among the main drivers behind the loss of biodiversity at the crop, farm and landscape levels. Half of the global food demands are met with only four major crops: wheat, maize, rice and potato, implying that 50% of the biota occurring on farmlands (i.e. plants, insects, pests, farm animals, birds, fungi and microbes of farm...
Overreliance on GM crops in general, and herbicide-resistant GM crops in particular, discourages the application of alternative weed control and insect pest management strategies. Since the very beginning of agriculture, all the developments have aimed at achieving higher yields and increasing farm income, with less focus placed on integrating the ...

Overall, the review finds that currently commercialized GM crops have reduced the impacts of agriculture on biodiversity, through enhanced adoption of conservation tillage practices, reduction of insecticide use and use of more environmentally benign herbicides and increasing yields to alleviate pressure to convert additional land into agricultu...
Dec 13, 2017 · The global food crop yield (1996–2013) has increased by > 370 million tonnes over a relatively small acreage area. 2 Furthermore, GM crops have been recorded to reduce environmental and ecological impacts, leading to increases in species diversity. It is therefore unsurprising that GM crops have been commended by agricultural scientists ...

Apr 8, 2024 · While these studies do not necessarily identify the contributions of GM crops, GM crops have resulted in reduced tillage, therefore the results of increased soil conservation practices are applicable to the continuous cropping, zero tillage production of GM crops.
