Regenerative Agriculture the Fruiticulture Way by Dr. David Klein

As humans are biologically, physiologically and anatomically best suited to a fruit-based diet, and because fruit is the best source of carbohydrate fuel for our cells, and because well-grown fruits are nearly nutritionally complete, and because nothing tastes more delicious than luscious fruits, and because every species of animal that eats its natural biological diet does not experience the toxemic and degenerative disease that humans do (unless fed cooked food and exposed to chemical pollutants), and because fruit trees beautify and improve every aspect of our ecosphere, we will be wise to replace agricultural lands that are devoted to grain and livestock farming with fruit-centric, regenerative agriculture  — ”Fruiticulture.”

Fruiticulture Defined

Fruiticulture is a conscientious, civilized, regenerative way of living in harmony with Nature, consonant with human’s natural dietetic character: frugivore. It is a culture of living reverentially, wholistically, symbiotically, synergistically, healthfully, and sustainably, employing biomimicry, diverse organic horticulture, and complementary “green” design practices, and establishing local and global communities and economies based on fruit, vegetable, nut and seed growing and eating.

Fruiticulture is the most sustainable form of agriculture for our planet. Its method is planting the gamut of vegetable crops under and between diverse fruit and nut trees, employing site-generated green waste mulch, compost, worm castings and remineralizing the soils with locally-sourced mineral-rich rock powder amendments as fertilizers. This naturally improves the fertility of the soil ecosystem, returning more to the soils than is removed, while sequestering CO2, reducing greenhouse gases, helping to stabilize the climate, regenerating the Earth, and creating nutritious food forests of abundance. Farmers can collect the seeds of a portion of their fruit and vegetable crops and grow independently of seed suppliers. Food forests would enhance every aspect of life on planet Earth!

“Permaculture offers a radical approach to food production and urban renewal, water, energy and pollution. It is a philosophy of working with, rather than against nature — the harmonious integration of the landscape, people and appropriate technologies, providing food, shelter, energy and other material and non-material needs, achieving a resource of great diversity and stability in a sustainable way. The design principles are equally applicable to both urban and rural dwellers.”
-Bill Mollison

“Fruiticulture is a way of life; a culture, a philosophy. At its very core, Fruiticulture is a way of designing all human systems so that they integrate harmoniously with ecology. Veganic Fruiticulture is the ultimate ideal for a sustainable, vibrantly thriving culture. There simply is no better way of living in harmony with Mother Nature and being true to our frugivorous
nature than to create cruelty-free, abundant fruit forests in
every open space available.”
-Jesse Krebs, Ph.D.

Toxic, Destructive Agriculture or Eco-friendly Food Forests?

Nothing depletes our soils so much as grain growing, corn in particular, and cattle farming. Livestock farming degrades land and water resources, while furnishing toxic food fare and cruelly inflicting death upon animals, and perpetuating the insidious culture of killing. Artificial fertilizers are toxic and contain few nutrients, ruining our soils and making them more subject to erosion. The crops they stimulate are nutrient-poor, especially lacking in vital trace minerals which the plants and we need to attain vigorous health and disease resistance. The use of herbicides, fungicides and insecticides severely disrupts or totally kills off beneficial predator insects, earthworms and the soil microbes that give our soils their fertility. These practices have killed off great populations of the bees upon which most fruit crop pollination depend, and they have made crippling and fatal human disease conditions commonplace in countries where conventional agrochemical farming is the norm.

The sensible alternative, vibrant, poly-crop food forests would dramatically enhance the ecological health of our planet, and enable those working in the toxic agrochemical industry find new, healthful green jobs!

“Only two percent of U.S. cropland produces fruits and vegetables.”

Food Production Numbers

In the table below are some relative figures showing the productivity of fruit, vegetable, nut, legume, grain and animal foods employing conventional farming methods. The table was included in an article that the late Dr. T. C. Fry wrote in the 1980s. I was not able to find the source. Although the figures are old, their impact on human welfare and world ecology is nevertheless startlingly self-evident. In my quest to compile recent crop yield statistics, I found numerous sources of fragmented data from different regions where different farming methods are used, rendering it impractical to pull together an updated unified chart based on consistent factors. Nonetheless, it’s certain that the cited fruit and vegetable production numbers are cogent and can be increased dramatically, even quintupled, using today’s advanced Fruiticulture farming methods.

In 2007, I interviewed David Blume (, one of the fathers of the Permaculture movement (Living Nutrition magazine volume no. 20 ). Mr. Blume stated: “During the ‘90s I pretty much focused on sustainable agriculture and farming. I had 450 people eating all their vegetables from my two-acre polycultural organic farm. Of course I’m sure they also bought other things. We were delivering 10 pounds of vegetables per person per week. And we never really had more than two-thirds of the farm in cultivation at any one time. The rest of the time it was in cover crop. We had about eight times the yield that the U.S.D.A. says is possible.”

If you ask any Permaculture farmer about optimum crop yields, he or she will likewise rave about numbers that far exceed those that conventional agriculture can achieve; the same holds true for the few but increasing legions of Fruiticulturalists.

“Regenerative agriculture provides answers to the soil crisis, the food crisis, the health crisis, the climate crisis and the crisis of democracy.”
-Dr. Vandana Shiva

Diet Numbers

The average human requires about a pound of food (dry weight) daily, varying somewhat with the foodstuff. Thus, an acre of bananas will, if it amounts to about 50% of the diet, support about 40 people. At the other end of the spectrum, comparably, it requires two acres of animal products to support a single human. In other words, bananas supply human needs not only better but they furnish about 80 times as much food per acre than does animal agriculture.

Fruits, nuts and vegetables generally supply us with some 20 to 80 times as much food per cultivated acre than if we eat animals and animal products—and far more if Fruiticulture methods are employed. Fruit and nut trees will grow on rough and rocky mountainous and hilly areas that cannot otherwise be cultivated. Furthermore, animals graze poorly in such areas and cause a tremendous amount of erosion or soil loss. Fruiticulture is feasible in all landscapes in non-polar regions, as Permaculture master Geoff Lawton has demonstrated time and time again — see: To learn how generous tree planting can dramatically transform a landscape and local climate, read The Man Who Planted Trees (1953) by Jean Giono.

“You can solve all the world’s problems in a garden.”
-Geoff Lawton

The Great Potential

Fruiticulture food forests can be implemented not only at farms, but in all urban and suburban settings: from residential properties with lawns and woods, to city parks, to highway parkways, to school and hospital grounds, and all other green and empty spaces. These will feed and beautify our world, and improve air quality and climate stability. The gains in human and animal health would be epic!

If America were to devote as much to fruit, nut and vegetable agriculture as it presently devotes to animal agriculture, it would feed perhaps five times as many people as it presently does. The world can feed 10 to 30 times its present population, if the best use were made of our resources. Local green economies would thrive and displace toxic meat and junk food industries. Disease rates and healthcare needs would plummet. Hospitals would be nearly empty; the medical and pharmaceutical industries would become nearly obsolete.

If the world were to adopt Fruiticulture and embrace natural health education, as taught in our Fruiticulture book, and we will offer at Hua Nui, and as we currently offer via our Vibrant Health & Wealth Academy, this could arrest and possibly reverse the impending catastrophic effects of climate change, eliminate diet-related diseases, and make the whole world a veritable Garden of Eden, a peaceful planet of abundance and unlimited vibrant health. The time is ripe!
