Main features of Shifting Cultivation • The following characteristics could be describe/explained • Clearings made in the rainforest by cutting and firing trees (slash and Burn) • Largest trees often left because they are difficult to move and can provide a source of food in the form of fruit. • Ash is scattered after trees have been burned to fertilise the ground. • Little fertiliser is added apart from the ash, so the nutrient levels drop quickly leading to the cultivators abandoning the plot and finding a new one after 7-10 years. • Labour intensive little use of machines (some have chain saws). Crops tend to be planted using digging sticks. • Crops planting between remaining tree trunks which decompose slowly adding extra nutrients into the soil. • When the clearing is abandoned it is left for many years, allowing the vegetation to recolonise. • With a low population density this form of agriculture is sustainable.
