Introduction

Agriculture lies at the center of global environmental challenges, contributing significantly to greenhouse gas emissions, biodiversity loss, and soil degradation. Conventional production systems—characterized by intensive input use and monocultures—often prioritize short-term yields over the long-term health of ecosystems. Ecological agriculture offers an alternative approach that applies ecological principles to farming in order to create resilient, sustainable, and equitable food systems. By promoting biodiversity, reducing dependence on external inputs, and strengthening ecological interactions, ecological agriculture is increasingly recognized as a solution to the intertwined crises of climate change, food security, and environmental degradation.

Principles and Transition Toward Ecological Agriculture

Ecological agriculture operates along a continuum of transition—from incremental efficiency improvements and replacement of harmful practices to a full redesign of systems. Its key principles include enhancing biodiversity, improving soil and livestock health, optimizing nutrient cycles, and reducing reliance on external inputs. While conventional agriculture tends to simplify ecosystems, ecological agriculture embraces complexity by integrating diverse species, habitats, and management strategies. This transformation enables farms to function more like natural ecosystems, where ecological processes generate stability, productivity, and resilience.

Benefits of Biodiversity

One of the core principles of ecological agriculture is its positive impact on biodiversity. By creating diverse habitats and ecological niches, these systems support a wide range of organisms—from soil microbes to pollinators. Increased biodiversity strengthens ecological functions such as nutrient cycling, pest control, and pollination. Unlike systems dominated by uniform monocultures, ecological landscapes foster coexistence among species and functional groups, reducing vulnerability to disturbances and enhancing ecosystem resilience.

Climate Change Mitigation

Ecological agriculture contributes to mitigating climate change primarily through improved soil carbon storage and reduced nitrous oxide emissions. Practices such as diversified cropping, ecological fertilization, and reduced soil disturbance increase the soil’s capacity to act as a carbon sink. These interventions also enhance nutrient use efficiency and reduce nitrogen losses that lead to greenhouse gas emissions. Although the outcomes related to carbon dioxide and methane vary due to complex biological interactions, consistent improvements in soil carbon and nitrogen cycles demonstrate the strong potential of ecological agriculture to mitigate climate change.

Synergies and Trade-offs

Ecological interventions often create synergies between biodiversity benefits and climate change mitigation. Healthy soils enriched with organic matter function both as carbon reservoirs and as foundations for diverse microbial and plant communities. These mutually reinforcing effects strengthen the ecological base of farming systems. However, trade-offs may also occur—particularly when emission-reduction measures conflict with short-term productivity or biodiversity goals. The main challenge lies in designing strategies that balance these dimensions while maintaining long-term sustainability.

System-Level Transformation

The greatest benefits of ecological agriculture arise when interventions go beyond isolated practices to achieve integrated system-level redesign. Efficiency improvements and input substitution offer initial gains, but full reorganization of agricultural systems around ecological principles yields deeper and more lasting outcomes. By placing biodiversity and ecological processes at the heart of production, ecological agriculture enables farms to deliver not only food but also a wide range of ecosystem services—such as climate regulation, water purification, and soil conservation.

Conclusion

Ecological agriculture provides a comprehensive response to the environmental and social challenges facing modern farming. By enhancing biodiversity, improving soil health, and contributing to climate change mitigation, it offers a framework for developing resilient and sustainable food systems. Although trade-offs exist, the overall evidence shows that ecological agriculture represents a promising pathway for aligning agricultural production with environmental integrity and social well-being. Continued research and supportive policies are essential to accelerate the transition toward ecological systems and fully realize their potential in achieving global sustainability goals.

To date however, the effects of farming systems and management practices associated with agroecology (i.e., agroecological interventions) on biodiversity and climate change mitigation have not been systematically reviewed. Here, we perform a meta-analysis using observational and experimental studies to assess the effects of agroecological interventions on taxa diversity, as well as on greenhouse gas emissions (GHG) and carbon storage in Europe.
