Oldeman’s Agroclimatic Zone Shifting Analysis and Suitability of Agricultural Land in Bali

Due to climate change, the land suitability for several commodities no longer be the same. Agricultural conditions in Bali province will be expected to face uncertain climate patterns in the future. Therefore, the climate information required by farmers. By knowing the information, they expected able to suit their cultivation planning to the latest climate types information. One of climate information is climate types classification presented as Oldeman’s Agroclimatic Zone Map. It resulted by identification of climate types shifting areas. Areas where the wet or dry months become shorter or longer will cause the cultivation period for a commodity to be disrupted, which can reduce crop yields. The research regarding climate types shifting is important to find out which areas experienced in shift and what type of it. The aim of the research is to analyze Oldeman’s climate types shifting every decade in the 1991 -2020 period to determine the suitability of land to climate for paddy (Oryza sativa), corn (Zea mays), soybean (Glycine max.), chili (Capsicum annuum) and shallot (Allium oscolonicum) in 58 locations to represent all sub-districts in Bali. The results showed that 49 (84.48%) locations experienced shifting.
