Feeding a global population projected to reach 8 to 10 billion by 2050 presents critical challenges for agriculture, demanding innovative strategies to enhance crop resilience and conserve natural resources. Traditional agricultural practices, heavily reliant on synthetic fertilizers, pesticides, and irrigation, have significantly increased food production but at the cost of environmental degradation contributing to soil erosion, water pollution, biodiversity loss, and greenhouse gas emissions. To ensure sustainable food production, it is crucial to adopt next-generation agricultural systems that reduce dependence on harmful inputs while boosting crop productivity and resilience. Environmental biotechnology offers transformative solutions through advanced genetic engineering and the utilization of plant-beneficial microbes. These approaches enable the development of crops with enhanced resistance to biotic stresses, such as pests and diseases, and abiotic stresses, including drought, salinity, and heat exacerbated by climate change. Furthermore, practices like the incorporation of cover crops and microbial inoculants play a pivotal role in improving soil health by enhancing nutrient cycling, reducing erosion, and controlling pathogens, thus supporting sustainable farming practices. This review highlights three case studies in small grain, tomato, and oilseed rape production, illustrating the success of cover crops and microbial technologies in improving soil fertility, controlling weeds, and reducing chemical inputs. Although these systems approximate conventional yields, further advancements are needed to significantly increase agricultural productivity. Developing new crop varieties with enhanced tolerance to environmental stresses and improved nutritional profiles will be essential. Achieving this requires the integration of cutting-edge biotechnology, including intensified genetic engineering and sustainable farming techniques. By harnessing the power of environmental biotechnology, we can address the dual challenges of global food security and natural resource conservation for future generations.
