The rapa nui environment prevented more sustainable options: irrigation was not possible, fruit orchards could not be established, native forest cover offered no edible foods. Greater risk: higher wind speeds, greater evaporation, higher surface temperatures, no natural organic inputs into the soil. Not enough food: plants may be damaged by winds, not enough moisture, prevents maturation of the tubers, lowers overall crop yield. The rock garden was developed as an environmental buffer. Five forms of gardens can be identified. Reduces temperature extremes and lowers ground temperature average. Rapa nui farmers practiced a program of fertilization to increase yields. More remote fields receive less fertilizer and may be depleted in phosphorus. In another words-get to work or you"re fired!
