The cultivatable land suitability terms as degree of land suitable for cultivations. The authors take 0.5° x 0.5° grids of the world as the analysis basic units, 5′ x 5′ as spatial resolution. The global cultivatable land suitability dataset based on physical-geographic factors was developed by integrating 13 physical-geographical factors, which affects the cultivation intensity, such as climate, soil, topography and etc, with Pearson correlation analysis. The data result indicates that the spatial distribution pattern of cultivatable land suitability is basically consistent with the value of reclamation rate. That is, in the main agricultural areas in the world (such as plains in Eastern European, North China, Ganges, Central North America, etc.), it generally shows a high reclamation intensity, while in areas with relatively extremely conditions for cultivation, the value of cultivatable land suitability is generally very low. The dataset is archived in .img format, and consists of 4 data files with data size of 38.7 MB (compressed to one file with 3.55 MB).Browse
