On the island of Bali in Southeast Asia, rice farming is a way of life. The people live in tune with the natural rhythms and cycles of the water and the soil. Ingrained in their community and culture, rice farming connects them to the land and one another. Balinese farmers have planted rice using an intricate system of water sharing and crop rotation for more than a thousand years. Intertwined with their spiritual, social, and day-to-day lives, this system has made Bali a leading producer of one of the world’s most important crops. And because Balinese rice farming respects the balances of nature, it serves as a remarkable example of sustainable agriculture in an increasingly industrialized world. With lush photographs and captivating text, Jan Reynolds explores the traditional world of rice farming on the beautiful island of Bali. Readers of all ages will come away with an enhanced awareness of how we farm, eat, and live today, and the effects these practices have on the world of tomorrow.
