Benefits of multi-paddock grazing management on rangelands: Limitations of experimental grazing research and knowledge gaps

This paper refutes recent research that finds no benefits for vegetation or animal production under “multi-paddock rotational grazing” in comparison to continuous grazing. It finds that these studies were small scale and fixed protocol experiments that did not adequately match the experience of successful managers.   Four key factors in successful “multi-paddock rotational grazing” are… Read more »

Rangeland Management for Improved Pastoralist Livelihoods: The Borana of Southern Ethiopia

Read full article: “Rangeland Management for Improved Pastoralist Livelihoods: The Borana of Southern Ethiopia“
Summary: This dissertation asks what can be done to revitalise degraded rangelands, and suggests that Holistic Management can help practitioners and pastoralists re-apply indigenous knowledge and skills under modern conditions to re-establish a dynamism important to rangeland health. Holistic Management uses… Read more »

Controlled intensive grazing: Savannah Grasslands, Africa

Read full article: “Controlled intensive grazing: Savannah Grasslands, Africa“
Summary: This chapter appears in a book about sustainable land management, the development of water buffers, and the business case in favor of investment in natural resource management. The financial payback, economic dividend, and social impact of investing in integrated landscapes – if done properly –… Read more »

What place for livestock on a re-greening earth?

Read full article: “What place for livestock on a re-greening earth?“

Summary: This paper contemplates the role of livestock and livestock management in providing helpful ecosystem services, “re-greening the earth,” through a literature review considering both the well documented injurious and highly beneficial outcomes of ruminants on landscapes, such as promoting perennials on landscapes. It thus… Read more »

Regarding Holechek and Briske, and Rebuttals by Teague

Read full article: “Regarding Holechek and Briske, and Rebuttals by Teague, Gill and Savory“

Summary: This paper investigates the grazing management assessment reports authored by university researchers David Briske and Jerry Holechek that were critical of methods they had attributed to Allan Savory. Criticisms of the Briske and Holechek assessments are provided from three sources: rancher,… Read more »

Origin, Persistence, and Resolution of the Rotational Grazing Debate: Integrating Human Dimensions Into Rangeland Research

Read full article: “Origin, Persistence, and Resolution of the Rotational Grazing Debate: Integrating Human Dimensions Into Rangeland Research“

Summary: This paper examines the origins of the “rotational grazing” debate in range management and suggests that discrepancies between scientific findings and manager experience can be rectified through a context of “complex adaptive systems” where social and biophysical… Read more »

Critical choices for crop and livestock production systems that enhance productivity and build ecosystem resilience

Read full article: “Critical choices for crop and livestock production systems that enhance productivity and build ecosystem resilience“

Summary: This report provides an overview of systems of production that reduce negative agricultural impacts on the use of soil, water, and biological resources; many highlighted approaches (e.g. maximizing crop residue, enhancing nutrient and water cycles, etc.) regenerate… Read more »

Multi-paddock grazing on rangelands: Why the perceptual dichotomy between research results and rancher experience?

Read full article: “Multi-paddock grazing on rangelands: Why the perceptual dichotomy between research results and rancher experience?“
Summary: Much anecdotal evidence from producers suggests that, if applied appropriately, multi-paddock grazing can improve forage and livestock production. By contrast, recent reviews of published rangeland-based grazing systems studies have concluded that, in general, field trials show no… Read more »

Hawkins’s 2017 Meta Analysis of Holistic Planned Grazing Should be Retracted

Read full article: “Hawkins’s 2017 Meta Analysis of Holistic Planned Grazing Should be Retracted“
Summary: This paper refutes Hawkins (2017), “A global assessment of Holistic Planned Grazing™ compared with season-long, continuous grazing: meta-analysis findings,” which argues that Holistic Planned Grazing (HPG) is not superior to year long continuous grazing. It is shown that none of… Read more »
