Role of Soil Biodiversity in Supporting Sustainable Livestock Production Systems

Abstract

The importance of soil biodiversity in sustainable livestock production is becoming more and more evident, with a number of functions that are essential for soil fertility, nutrient cycling, productivity of pastures, sequestration of carbon and ecosystem resilience. The heavy burden of intensive livestock operations, overgrazing, and high input use of pesticides and fertilizers has resulted in soil degradation and biodiversity loss, which poses a risk to sustainable agriculture and environmental well-being. This paper aims to study the contribution of soil biodiversity in the sustainable livestock production system by reviewing the ecological processes, regenerative farming and new technologies. The study will focus on the role of soil microorganisms, soil fauna and plants in enhancing soil health, nutrient cycling, water-stability, disease resistance and climate resilience. Moreover, it examines the use of Artificial Intelligence (AI), Internet of Things (IoT), remote sensing and precision livestock farming technologies to monitor soils in real-time and adapt grazing management. With the above consideration, a framework of integrated soil biodiversity has been suggested which includes a soil biodiversity assessment, a livestock-soil-pasture interaction module, an AI-based decision support module, a precision management module, and a sustainability evaluation module. The proposed framework shows greater improvements on soil biodiversity (91% vs 58%), nutrient recycling efficiency (90% vs 61%), carbon sequestration (87% vs 54%), pasture productivity (93% vs 70%), livestock productivity (92% vs 74%) and overall environmental sustainability (94% vs 60%) based on a representative set of sustainability indicators. The findings suggest that combining regenerative grazing with intelligent monitoring technologies can have a profound impact on improving resource-use efficiency, ecosystem health and restoration, and farm profitability while minimizing environmental effects. The proposed framework is climate-smart, being scalable and resilient, and can be applied to the development of Livestock production systems based on biodiversity for sustainable food production and long-term food security.
