Data underlying the publication: Small-scale and large-scale agriculture across water-scarce and water-abundant regions

We aim to estimate the geographic distribution of small-scale and large-scale agriculture across water-scarce and water-abundant regions, their blue and green water consumption, and the water stress (stress from a lack of blue water) and soil fertility stress on their crop. We combined three definitions of small-scale agriculture and used a soil fertility-enhanced crop model to estimate crop production and water consumption.<br>This dataset contains country-level and grid-level results (55 countries).

本研究旨在估算缺水与富水区域内小尺度农业与大尺度农业的地理分布格局，及其蓝水（blue water）、绿水（green water）消耗量，以及作物面临的水分胁迫（由蓝水匮乏引发）与土壤肥力胁迫。本研究结合三种小尺度农业的定义，并采用土壤肥力增强型作物模型估算作物产量与水分消耗量。
