Food forests and shared prosperity
At age 40, Yamman found a new life goal in the "food forest" concept.
Before then, he had worked in construction and satellite television. The high-pressure lifestyle had him smoking three packs of cigarettes and chewing several packets of betel nut per day, and his weight soared to over 100 kilos at one point. His quest for success had put his health in danger. Suffering from severe allergies, he decided he had to leave his job and take drastic steps to regain his health. He went to mainland China to study traditional Chinese medicine in Wu-han, and naturopathy in India. After learning about permaculture in 2005, he decided to establish Yamana Garden because "for people to be healthy, we must first have a healthy environment."
In addition to the food forest, Yamman also adopted the "three sisters" crop system originated by indigenous peoples in South America, who plant corn, squash, and beans together in a way that allows for symbiosis between them. The corn is planted first, and once it grows to about 15 centimeters they plant beans, which climb up the cornstalks. The beans provide nitrogen, which is needed in large quantities by the corn. The squash, in the meantime, spreads along the ground, where its large leaves make for the perfect mulch, blocking the sunlight, inhibiting the growth of weeds, and protecting the soil.
The concept of permaculture was first introduced in Taiwan by an American married to a local woman.
Peter Morehead, a major in botany at Wisconsin University who since childhood had enjoyed identifying edible plants and tracking wildlife, came to Soochow University in 1991 as an exchange student to study Chinese. Within three years he had met and married -Jiang Huiyi and settled down for the long haul in Taiwan.
The couple lived back then in an apartment in New Taipei City. The concrete-bound existence grated on him, and so in 1998 at the suggestion of a Canadian friend he decided to take a course in permaculture in Australia. After returning to Taiwan he rented out a plot in Beitou and started planting crops there.
In a corner of the rooftop garden at Morehead's home, there are to be found a water tank, some papaya trees, and a compost bin. The papaya trees provide shade for the water tank and smaller plants. The water tank lowers the temperature, serves as a windbreak for the surrounding environment, and reflects sunlight back to the papaya trees. The yams he planted there climb up the papaya trees, and green beans planted subsequently are now climbing their way up the yams. The compost bin, meanwhile, shelters the garden from the wind and creates a cooler microenvironment.
Morehead explains that when people hear the word "forest" they get the wrong idea that you're talking about planting crops in the hills, but in fact a food forest can be modified to suit any particular environment. Where water tends to collect, for example, you can plant a ring of banana trees numbering anywhere from a few to several dozen, and then carry out composting within the ring. "The banana root system absorbs a lot of water, and the compost pile fertilizes the trees."
Crops eaten in season are best for one's health. Shown here are rice harvested at Yamana Garden, and two varieties of ginger from Yang Wenxian's farm.
