Crop Data
The most recent crop data file has 14,519 rows and covers the 1985-2022 period. Besides the “data” tab, the file contains 4 other tabs (admin, season, crops, metadata).
The metadata tab is a new one, listing previous metadata already in the FDW, and new entries that will have to be added before uploading.
In the new data, the Dominant Production System field is more complex than usual because the original source data are reported in multiple, non-overlapping production systems that were not previously captured. New “PS” codes will need to be entered into the FDW (see below, and in the Metadata tab).
Context for these: Most crops are grown during the main rainy-season by small-holders with few resources.
Plaine/Bas-fond irrigated (PS): In BF there has been extensive development of “plaines” (irrigated fields with bunding) and “bas-fonds amenagés” (irrigated bas-fonds, or low-lying areas that may fill during the rains, and which are irrigated using that rainwater, or other drawn from a near-by source: ergo, not necessarily just rain-fed). Some of these areas are managed by cooperative groupings, and others may be small-scale commercial in nature. Some of these may be growing veggies and other crops outside of the rainy season, although not reported.
Bas-fonds rainfed (PS): There is another more-common bas-fonds farming system that is only fed by rainfall and is not irrigated or managed (amenagé) in the same way.
Rainfed (PS): everything else that is grown in fields, often dispersed and planted with multiple crops, during the rainy season without irrigation and with few resources.
Season dates in the FDW now are wrong. They are corrected in this spreadsheet. See the “Season” tab in the spreadsheet describing correct seasons and dates (not all of which are used here in these data).
In the BF admin evolution, former AD1 “provinces” were demoted in 2001 with AD1 “regions” being inserted above them. FEWS does apparently have FNIDS (and shapefiles?) for current AD3.
Some previous crop codes (eg cowpeas) were updated to more current codes, and 3 new crops (using existing FDW CPCV2 codes) are added.
There are new FNIDs for recent data, and the “admin” tab shows the evolution of each.
