I read somewhere that in the medieval ages European farmers considered that Nature did the work. Their task as farmers was merely to harvest what nature produced, and for some crops also to plant. This way of looking at natural resource management adds a new aspect to the idea of a “Thanksgiving Day” – which is still celebrated in Swedish churches at the end of the harvest season, with samples of root crops, vegetables, berries etc. placed by the altar. I guess the thinking among the Dayak is similar, when they celebrate their Gawai after the rice harvest.
