Managing soils for negative feedback to climate change and positive impact on food and nutritional security

This paper by Dr. Rattan Lal detailing the scope of nature-based climate solutions, including but not limited to grasslands and soils. Findings show that “the soil C sink capacity, between 2020 and 2100, with the global adoption of best management practice which creates a positive soil/ecosystem C budget, is estimated at 178 Pg C for soil, 155 Pg C for biomass, and 333 Pg C for the terrestrial biosphere with a total CO2 drawdown potential of 157 ppm.”

Ecosystem Impacts and Productive Capacity of a Multi-Species Pastured Livestock System

This paper conducted a whole-farm life cycle assessment (LCA) of a multi-species pasture rotation (MSPR) farm in the southeastern United States that was originally converted from degraded cropland. Results showed an average of 2.29 Mg C ha−1 yr−1. Incorporation of soil C sequestration into the LCA reduced net GHG emissions by 80%, resulting in a footprint 66% lower than commodity production systems.

Holistic Management and Adaptive Grazing: A Trainers’ View

The authors avoid the usual debates on whether or not Holistic Management, Holistic Planned Grazing, or any its many derivatives deliver outcomes as claimed by practitioners, and instead focuses on their contribution to managing complexity. Holistic Management’s biggest acknowledged contribution to the grazing world is (arguably) its emphasis on adaptivity, strategic decision-making, goal-setting, and ability to manage complexity. Based on data gathered from educators in American and Canada who have trained many farmers and ranchers, the authors conclude that Holistic Management represents systems thinking in practice.

The Effect of Holistic Planned Grazing on African Rangelands: A Case Study from Zimbabwe

South Africa’s Agricultural Research Council completed this study over a 6-year period comparing the Africa Centre for Holistic Management’s land at Dimbangombe under Holistic Planned Grazing (HGP), to nearby communal areas where HPG was not practiced. The researchers concluded that HPG yields positive long-term effects on ecosystem services (soils and vegetation) and points to the HPG approach enhancing the sustainability of livestock and wildlife in this environment.
