Abstract

Abstract: Shifting cultivation by Dayak Iban Tribe in Mensiau Village have several stages, namely burn the land, rice cultivating for two or three planting seasons, and abandoned for reforestation. Vegetation growth through several stages on one cycle, ideally started from burn scar, rice field, bushes, young secondary regrowth, old secondary regrowth, then become secondary forest, so that cycle needs 20 years. The aim of this study is to identify the spatial characteristic of shifting cultivation from UAV data, calculating the change on cycle from Landsat NDVI temporal analysis, also calculating the distance from home and access to the field using Euclidean Distance Analysis. The result shows most of shifting cultivation happen on hilly area with 15-25% slope and Ultisol soil type. NDVI analysis for some field shown increasing of cycle time from 3 to 5 year, and distance analysis reveal that shifting cultivation mostly take place near the roads.
