Robert Paarlberg argues that anti-science environmental groups and corrupt local governments deprive African farmers of the crops needed for progress.
Graham Strouts takes critical look at whether the forest gardens championed by many permaculture enthusiasts can produce food in yields significant enough to compete with traditional orchard and farming systems outside of tropical climates.
Graham Strouts deconstructs the meaning and definition of permaculture and exposes the lack of data, rigor, and evidence to support any claims for superior productivity or environmental impact to the modes of production it is meant to serve as an alternative to.
When all is said and done, any contribution permaculture has to make will be practices that work will work independent of the whole edifice. Just as “alternative medicine” that works is just called “medicine” so anything that could be shown to work in what is called “permaculture” is simply “good farming”, “good design” or “good engineering”.
