ERA Africa

The Evidence for Resilient Agriculture (ERA v1.0.1) dataset contains observations from agricultural studies conducted in Africa from 1934 to 2018. ERA examines the efficacy of agricultural practices on environmental, social, and agricultural-economic outcome indicators. For AGROSTAC the phenology (start and end) was extracted.

Pre-processing

Original data of file '01a. ERA_Compiled.csv' was repaired, merging splitted lines, and afterwards processed and filtered:

• Only include records that have information on the journal, DOI, Product.Simple (crop label)
• Only include observations of arable annual crops
• Only extract the sowing and harvest date
• At least one of the fields of Plant.Start, Plant.End, Harvest.Start or Harvest.End must have a value
• The record was not copied if there is no valid planting date and no valid harvest date
• The record was not copied if the planting date and harvest date differ by less than 90 days
• The record was not copied if Plant.Start and Pant.End differ by more than 30 days
• The record was not copied if Harvest.Start and Harvest.End differ by more than 30 days

The unique name is constructed from the initial string 'ERA_Africa_', concatenated with the attributes:

• Site.Key
• DOI
• Product.Simple

and finally a sequence number in case if multiple treatments.

The comment is based on the following attributes:

• Site.Key (latitude and longitude)
• DOI
• Product.Simple (crop label)

The geometry accuracy is taken from the attribute Site.Key. Elevation is only loaded if the elevation field in the .csv file consists of one number.

CROP_CODE

Attribute: Product.Simple

Remark: selected annual arable crops

CROP_DEV_BBCH

Attribute: Plant.Start, Pant.End, Harvest.Start and Harvest.End

Remark:

• If there is a Plant.Start and a Plant.End, the average was taken, rounded to the nearest date
• If there is a Harvest.Start and a Harvest.End, the average was taken, rounded to the nearest date

Management

There was no further information on the crop management.
