Holistic Management : Misinformation on the Science of Grazed Ecosystems

الملخص EN

Over 3 billion hectares of lands worldwide are grazed by livestock, with a majority suffering degradation in ecological condition.

Losses in plant productivity, biodiversity of plant and animal communities, and carbon storage are occurring as a result of livestock grazing.

Holistic management (HM) has been proposed as a means of restoring degraded deserts and grasslands and reversing climate change.

The fundamental approach of this system is based on frequently rotating livestock herds to mimic native ungulates reacting to predators in order to break up biological soil crusts and trample plants and soils to promote restoration.

This review could find no peer-reviewed studies that show that this management approach is superior to conventional grazing systems in outcomes.

Any claims of success due to HM are likely due to the management aspects of goal setting, monitoring, and adapting to meet goals, not the ecological principles embodied in HM.

Ecologically, the application of HM principles of trampling and intensive foraging are as detrimental to plants, soils, water storage, and plant productivity as are conventional grazing systems.

Contrary to claims made that HM will reverse climate change, the scientific evidence is that global greenhouse gas emissions are vastly larger than the capacity of worldwide grasslands and deserts to store the carbon emitted each year.
