Takao Furuno (born 1950) is a Japanese farmer, social entrepreneur, philanthropist, private aid volunteer, and pioneer of the duck-rice farming, known as aigamo in Japanese.
After ten years of using organic farming practices, Furuno learned of a traditional Japanese rice farming method that consisted of using ducks to eliminate the weeds in rice fields, the "Aigamo Method." His first experiment was a success, but not without problems. In this system, ducklings are introduced into rice paddies for the purpose of (1) providing natural fertilizer, (2) to strengthen the rice seedlings by oxygenating the water from the turbulence caused by the ducklings' swimming actions, as well as (3) to weed and eat insects. One season, disease destroyed Furuno's entire crop. For three years, dogs ate his ducks until he installed electric fences. Then, Furuno had to ward off birds of prey, who would fly into the paddies for a quick meal.[4]
By continuous observation and research, however, Furuno was able to identify the optimal age at which ducklings should be released into rice fields (7 days), the number that should be introduced for every tenth of a hectare (15-30), and the moment when the ducklings should be removed from working in a paddy (8 weeks) so as not to eat the rice. Through experimentation, he discovered, too, that the addition of loaches (a type of freshwater fish) and the nitrogen-fixing weed Azolla to the fields boosted rice and duck growth, and simultaneously supplied nutrition for the ducks. Wires strung at intervals across the fields deterred the birds of prey.
By 1989, he had re-engineered the method into a sustainable, integrated organic rice and duck farming system that could be replicated. Today, in addition to protecting his family’s health, Furuno now produces crop yields without the use of chemicals that equal or surpass those of farmers still using conventional methods. Furuno has successfully marketed duck rice, which now sells at a 20-30% premium over conventionally grown rice in Japan and other countries. Today, his 3.2-hectare farm produces rice, organic vegetables, eggs, ducks, and ducklings.[5]
Through his writings, travels, lectures and cooperation with agricultural organizations and governments, his methods have spread to more than 75,000 farmers in Japan, Korea, China, Vietnam, the Philippines, Laos, Cambodia, Malaysia, Bangladesh, Iran, and Cuba. The adoption of this method boosts a farmer's income, decreases their workload, and reduces environmental damage, while increasing local and regional food security. When the ducks are no longer needed, they are used as table birds or sold to add considerably to the family income and protein intake. Farmers using the aigamo method also have more time to spend with their family or doing other things. In the past, it has been estimated that manual weeding of paddies requires 240 person-hours per hectare every year.[6]
