We constructed a novel method of market gardening: Synecoculture, based on the high-density mixed association of edible plants without the application of tillage, fertilizer, and chemicals.

We introduced a high crop diversity (200 species, 700 varieties in 1000㎡) for year-round sustainable harvests. This was shown to strengthen food security, nutrition profile, soil quality, cost efficiency, climate adaptation and field biodiversity.

In Japan, 2- to 4-fold productivity was attained compared to conventional method.

In Burkina Faso, 40- to 150-fold productivity and 10-fold cost-effectiveness was realized in the arid tropic region.

Linear extrapolation of the result shows a strategic propagation of synecoculture could lift the entire population of Burkina Faso above the poverty threshold, and substantial achievement of Aichi biodiversity targets.
