Sustainability of Livestock Farming Systems

The sustainability of livestock farming systems hinges on balancing environmental integrity, economic viability and social welfare across diverse production models. Key environmental concerns include greenhouse-gas emissions, land degradation, water scarcity and biodiversity loss, while economic pressures derive from fluctuating market prices, policy incentives and input costs. Social dimensions encompass rural livelihoods, animal welfare and community well-being. Contemporary research adopts integrative frameworks—such as life-cycle assessment, emergy accounting and the water-energy-food nexus—to quantify trade-offs and co-benefits. Intensification can lower emissions per unit of product but may threaten soil health and equity in resource access, whereas extensive systems often promote biodiversity yet depend heavily on external subsidies. Emerging innovations span feed additives to reduce methane, precision grazing to enhance pasture resilience and circular models that valorise manure and by-products. The drive towards resilient livestock systems reflects global commitments to climate targets, food security and circular economy principles, with tailored approaches required for mountain grazing, smallholder dairying and ruminant meat production across temperate, tropical and peri-urban contexts.

Research from Nature Portfolio

Recent studies have applied emergy accounting to assess mountain grazing agroecosystems in the Spanish Pyrenees over the past three decades. This analysis demonstrates a growing dependence on non-renewable energy and material inputs—driven largely by public economic support—which has paradoxically transferred unsustainability into systems conventionally viewed as low-impact. Despite extended grazing duration and reduced external feed use, the influx of subsidy-derived services elevates the emergy footprint and underscores the need for policy realignment towards renewable resource flows and ecosystem stewardship.

The graph below shows the total number of articles in sustainability of livestock farming systems across all publications each year (not limited to Nature Index journals).

Technical terms

Emergy accounting: Evaluation method that converts all energy and material inputs into a common unit of solar-energy equivalents to assess true systemic resource dependence.

Life-cycle assessment (LCA): Holistic framework for quantifying environmental impacts throughout the full life cycle of a product or system, from resource extraction to end-of-life.

Water-energy-food nexus: Integrated approach that examines interdependencies among water, energy and food systems to ensure balanced resource management and resilience.

System dynamics: Modelling technique that simulates interactions and feedbacks within complex systems to analyse policy scenarios and optimise resource flows.
