rotational grazing

Farmer Joel Salatin gives a TEDx talk on how well-managed grass and rotational grazing support sustainable farming and affect the climate. He draws on his work at Polyface Farm in Virginia.

A 47-minute documentary on Allan Savory and how he used Holistic Management to restore degraded land in Zimbabwe. It covers rotational grazing, soil health and regenerative agriculture.

Allan Savory's TED talk arguing that desertification of grasslands can be reversed with holistic managed grazing, which he says would also help reverse climate change. TED notes that other scientists have challenged his claims.

Veritasium explains the Dzhanibekov effect, also called the tennis racket theorem, where a spinning object flips unexpectedly about its intermediate axis. The video gives an intuitive account of the underlying rotational dynamics, drawing on Terry Tao's explanation and the original papers.

Farmer Gabe Brown talks about how he rebuilt the soil on his ranch using no-till farming, cover crops, and grazing animals. The talk was recorded at a sustainable agriculture symposium in Idaho in 2014.

Alan Watson Featherstone, founder of Trees for Life, describes nearly 30 years of work restoring the ancient Caledonian Forest in the Scottish Highlands, illustrated with his photography.

Scott Manley surveys the research on whether people can adapt to rotating artificial gravity, from early Soviet centrifuge tests to modern studies. He concludes it is an engineering problem and discusses Coriolis effects and station radius.

Josef Holzer walks through his family's Krameterhof, one of Europe's oldest permaculture farms in the Austrian mountains, with fish ponds, terraces, fruit trees and grazing animals. It showcases water management and microclimates.
