Dataset Description
This map set provides spatial indicators of climate, soil, and terrain resources relevant to agriculture, as well as population and agricultural resource poverty, all mapped at a 1-kilometer resolution. It also includes maps depicting precipitation probabilities and trends, growing periods, and agroclimatic zones, along with their changes across different reference periods.
The map set is included in Publication 112 (2016). For methodological details and further information, including interpretations of the various maps, is referred to the publication.
