Most of the locals are small-scale microfarmers who make a living from major grains and coffee cultivation, but they do not have enough income and depend on some unstable sources of income(cash crop cultivation), making them economically vulnerable.Before implementation of this project,they could only make a living by selling cash crops on limited land, and the amount of money(about 50 en per day) was well below the international poverty level(about 200 yen per day).Also, the time when this income was earned was only due to work during the farming season, and there was almost no work during the four months of the dry season.
