Exploration of Advantages in Grassland Agriculture: A Study on Pasture-Based Methods
In recent years, there has been a growing body of evidence supporting the resilience and viability of pasture-based livestock farming systems in addressing climate change, biodiversity loss, and socio-ecological disruption. These systems, when managed sustainably, can make significant contributions to the mitigation of climate impacts, the conservation of biodiversity, and the support of socio-ecological systems.
One key example of climate mitigation through low-impact grazing is the Chopan transhumant pastoralism in alpine Jammu and Kashmir. This system, which uses only about 10% of the ecological capacity, supports soil fertility, carbon sequestration, and biodiversity by converting underutilized biomass into protein without causing land degradation. Integrative grazing approaches, such as rotational and adaptive grazing, mimic natural herbivory, improving soil structure, microbial biomass, root development, and nutrient cycling. This promotes enhanced organic matter stocks and reverses soil degradation trends often observed in conventional or extractive grazing.
Advances in breeding for resilience traits (e.g., parasite resistance, heat tolerance, feed efficiency) and improved health and welfare protocols reduce emissions intensity per product and support animal well-being, creating more sustainable herds adapted to changing climates. Pastoral communities, using deep local ecological knowledge, apply rotational grazing, monitor pasture health, and maintain ecosystem balance, ensuring livelihoods while stewarding landscapes that would otherwise be ecologically underutilized or degraded.
However, challenges remain. Declining pasture yields and soil degradation are linked to decoupling livestock from pasture-based feeding and over-reliance on off-farm feed and synthetic inputs. Holistic planned grazing and integrated crop-livestock systems can reverse these trends and enhance resilience, productivity, and ecosystem services.
The Pasture for Life approach, which emphasises adaptive grazing, integrated management, and leveraging local knowledge and genetics, has been shown to be resilient and viable. This approach contributes significantly to the delivery of broader public goods, such as carbon sequestration, biodiversity enhancement, and socio-ecological resilience.
Dr Jordana Rivero and Dr Laurence Smith, researchers in the field, stress the importance of managing grazing systems and advocating for a more comprehensive assessment of agroecological systems to fully capture the multi-functional benefits of agricultural landscapes. The use of rapid farm-level multi-criteria sustainability assessment tools can complement Life Cycle Assessment results, help reveal 'blind spots', and encourage adoption by farmers.
In conclusion, pasture-based livestock farming systems, when managed sustainably, demonstrate strong evidence of resilience and viability in mitigating climate impacts, conserving biodiversity, and supporting socio-ecological systems. However, realizing their full potential requires attention to soil health, grazing intensity, and integration within broader agroecosystems. The Pasture for Life approach, with its focus on adaptive grazing, integrated management, and local knowledge, offers a promising path forward for sustainable livestock production.
