Conservation agriculture centres on three main practices: minimising soil disturbance, maintaining permanent soil cover, and diversifying crop species. Evaluating these practices demonstrates improvements in soil physical, chemical, and biological properties. Notable impacts include enhanced soil structure, greater organic carbon sequestration, stimulated microbial activity, higher water-use efficiency, and reduced soil erosion and nutrient loss. Alongside these environmental benefits, the approach supports broader outcomes such as biodiversity conservation, lowered greenhouse gas emissions, improved crop yields, and greater food system resilience. Integrating technological innovations, including precision agriculture, remote sensing, and digital farming tools, assists in scaling these practices. However, successful adoption depends heavily on local socioeconomic conditions, supportive institutional frameworks, targeted capacity-building, and tailored policy interventions to address existing implementation gaps.
Maintaining healthy soil is essential for long-term food production and climate resilience. By limiting soil disturbance and keeping soil covered, conservation agriculture helps farms adapt to climate pressures while protecting natural ecosystems. Understanding how digital technologies and targeted policies support these methods ensures that farming systems can sustain yields without degrading land or accelerating environmental decline.
The findings point to application opportunities for agritech developers, farm service providers, and agricultural policymakers. Precision agriculture tools, remote sensing services, and digital management platforms can be deployed alongside sustainable agronomic practices to boost farm productivity. Because these supporting digital tools and conservation techniques already exist and are being adopted, practical implementation sits near-market, although scaling requires locally tailored services and institutional support.

Conservation agriculture (CA) is widely recognized as the cornerstone of sustainable agriculture. It prioritizes minimizing soil disturbance, maintaining permanent soil cover, and diversifying crop species to restore soil health and ecosystem resilience. This review synthesizes the effects of CA on the soil’s physical–chemical and biological properties. It demonstrates its effectiveness in improving soil structure, enhancing organic carbon sequestration, promoting microbial activity, increasing water-use efficiency, and reducing erosion and nutrient losses. The paper then highlights the broad environmental, economic, and social benefits of CA. These include biodiversity conservation, reduced greenhouse gas emissions, improved yields, and increased food system resilience. The review explores the synergistic role of technological innovations such as precision agriculture, remote sensing, and digital tools in scaling CA for higher productivity and sustainability. The review then examines how socioeconomic conditions, institutional frameworks, and policy interventions shape CA adoption and impact. Despite its growing adoption, CA’s successful implementation will require strategies adapted for local needs, capacity-building, and supportive, inclusive policies. Finally, the review identifies key CA research gaps and future directions. This provides a comprehensive foundation to advance CA as a climate-smart, resilient, and sustainable pathway to ensure global food security and environmental stewardship.
