This dataset is supplement to the following publication (please cite that when using the data):
Kinnunen et al. 2020. Local food crop production can fulfil demand for less than one-third of the population. Nature Food 1: 229–237. http://doi.org/10.1038/s43016-020-0060-7
Data description
Distance to food: Globally optimized distance between crop production and consumption. The optimization creates a theoretical food allocation set-up that minimizes travel time cost from crop production to consumption. Data is in two formats: NetCDF (dist_food_netcdf.zip) and multi-band geotiff (dist_food_tif.zip).
The data includes:
baseline scenario (dist_food_baseline.nc / .tif)
and three other scenarios where food availability is changed by
decreasing food waste by half (dist_food_halfLoss.nc / .tif)
halving the yield gap (dist_food_halfYieldGap.nc / .tif)
both of these measures together (dist_food_halfLoss_halfYielGap.nc / .tif)
The data covers six crop functional types: maize, pulses, rice, temperate cereals, tropical cereals and tropical roots
Dataset specifications:
spatial extent: -180, 180, -90, 90 (xmin, xmax, ymin, ymax)
spatial resolution: 0.5 degrees
projection: long/lat WGS84
layers: 1: maize, 2: pulses, 3: rice, 4: temp_cereals, 5: trop_cereals, 6: trop_roots
no data value: -999
unit: km
Foodsheds: The data contains global foodsheds which are areas that are connected by food flows between raster cells. The food flows are from a theoretical food allocation set-up that minimizes travel time cost from crop production to consumption. In addition to normal foodsheds (values>0), there are two special cases: ridge-cells (value: -99) and unconnected single cells (value: -50). Ridge-cells are raster cells connected to multiple foodsheds, while being able to satisfy their own demand locally. Unconnected single cells are not connected to any other foodshed. Each positivie value is a crop specific id, signifying a connected foodshed area.

本数据集为以下学术出版物的补充配套数据(使用本数据时,请务必引用该文献):
Kinnunen等,2020年。《本地粮食作物生产仅能满足不足三分之一人口的需求》。《自然·食品》(Nature Food)1卷:229–237。http://doi.org/10.1038/s43016-020-0060-7
## 数据说明
### 粮食可达距离
本指标指作物生产与消费之间的全局优化距离。该优化方案构建了一套理论粮食分配体系,可最小化作物从生产到消费的运输时间成本。本数据包含两种格式:NetCDF(dist_food_netcdf.zip)与多波段地理栅格(multi-band geotiff,dist_food_tif.zip)。
本数据集包含:
- 基准情景(dist_food_baseline.nc / .tif)
- 另外三种通过调整粮食供应水平得到的情景:
1. 食物损耗减半(dist_food_halfLoss.nc / .tif)
2. 产量缺口减半(dist_food_halfYieldGap.nc / .tif)
3. 同时实施上述两项措施(dist_food_halfLoss_halfYieldGap.nc / .tif)
本数据集涵盖6类作物功能型:玉米(maize)、豆类(pulses)、水稻(rice)、温带谷物(temperate cereals)、热带谷物(tropical cereals)与热带块根作物(tropical roots)。
### 数据集规格参数
- 空间范围:-180, 180, -90, 90(x最小值、x最大值、y最小值、y最大值)
- 空间分辨率:0.5度
- 投影坐标系:经纬度WGS84
- 波段顺序:1: 玉米(maize)、2: 豆类(pulses)、3: 水稻(rice)、4: 温带谷物(temp_cereals)、5: 热带谷物(trop_cereals)、6: 热带块根作物(trop_roots)
- 无数据值:-999
- 单位:千米(km)
## 粮食流域(foodsheds)数据
本数据集包含全球粮食流域数据,即通过粮食流动将栅格单元相互连接形成的区域范围。该粮食流动源自一套最小化作物生产至消费运输时间成本的理论粮食分配方案。除常规粮食流域(取值>0)外,还包含两种特殊栅格类型:
1. 山脊栅格(ridge-cells):取值为-99,指同时连接多个粮食流域且可本地满足自身需求的栅格单元
2. 孤立无连接栅格(unconnected single cells):取值为-50,指未与任何其他粮食流域建立连接的栅格单元
所有正数值均为作物专属ID,用于标识对应的连通粮食流域范围。
