A roundup of Permaculture related research.
Unravelling the Food-Health Nexus
NEW REPORT: 'An overwhelming case for action' - expert panel identifies unacceptable toll of food and farming systems on human health. Industrial food and farming systems are making people sick in a variety of ways, and are generating staggering human and economic costs - according to a major new report from the International Panel of Experts on Sustainable Food Systems (IPES-Food). Decisive action can be taken on the basis of what we know, the Panel found, but is held back by the unequal power of food system actors to set the terms of debate and to influence policy.
THE POTENTIAL OF PERMACULTURE PRINCIPLES IN THE AGRIFOOD TRANSITION
The main question for this research was : How can a production system based on permaculture principles contribute to the agrifood transition? This study answered this question by comparing a permaculture system with a conventional potato system. The Unique Selling Points of permaculture were identified, which determine the future potential of permaculture. Due to its diversity and inherent social and ecological values, permaculture is expected to be able to respond well to future bioclimatic conditions and consumer demands, which conventional systems are less likely to excel in. The underlying ethics and principles foster resilience and flexibility and can be applied in any system, permaculture or not.
Cover crops have been promoted for their abilities to reduce erosion and retain soil nutrients. Now there is evidence that they can significantly reduce weed seeds. Crops such as red clover, planted after a main crop’s harvest, provide cover for insects such as ground beetles that feed on weed seed. Rodents are also important consumers of weed seeds and tend to prefer foraging under the shelter provided by cover. As a result, in fields planted with cover crops, three to four times more weed seed is eliminated.
