Classification Systems

Crop Monitor for AMIS Classification System

Specifically in the context of the Crop Monitor, GEOGLAM experts developed a simple classification system for evaluating and depicting crop conditions and drivers. This system was developed based on systems used by the Agriculture and Agrifood Canada (AAFC) and the JRC MARS, with inputs from the AMIS Secretariat. Crop condition classes are defined with respect to expected yield as compared to the average over the past five years (even though production is of ultimate interest, classifications are made considering prospects for yield. This is due to an inability to detect changes in cropped area in near real time in landscapes dominated by smallholder cultivation). Along with all crop conditions which are other-than-favourable, one or more drivers are provided which indicate the cause of the abnormal condition.

Crop Condition Classes

 ConditionDefinition
ExceptionalConditions are much better than average* at time of reporting. This label is used only during the grain-filling through harvest stages.
FavourableConditions range from slightly below to slightly above average at reporting time.
WatchConditions are not far from average but there is a potential risk to final production. There is still time and possibility for the crop to recover to average conditions if the ground situation improves. This label is only used during the planting-early vegetative and the vegetative-reproductive stages.
PoorCrop conditions are well below average. Crop yields are likely to be 10% below average. This is only used when conditions are not likely to be able to recover, and impact on production is likely.

Drivers of Crop Conditions

DriverDefinition
WetWetter than average.
DryDrier than average.
HotHotter than average.
ColdCooler than average.
Extreme EventsCatch-all for all other climate risks (i.e. hurricane, typhoon, frost, hail, winter kill, wind damage, etc.). When this category is used the analyst will also specify the type of extreme event.
Note: "average" refers to behavior over the 5 most recent years

Crop Monitor for Early Warning Classification System

Crop condition classes observed in the Crop Monitor for Early Warning system are the same as with the AMIS Crop Monitor, with the addition of the “Failure” class. Failure is designated when crop yield is expected to be more than 25% below average. Much like the Crop Monitor for AMIS classification system, drivers of crop conditions are provided for all conditions which are other-than-favourable. However, additional driver types are included in the Crop Monitor for Early Warning classification scheme in recognition of the significant differences in agricultural weather and practices in the Early Warning regions.

WatchConditions are not far from average but there is a potential risk to final production. There is still time and possibility for the crop to recover to average conditions if the ground situation improves. This label is only used during the planting-early vegetative and the vegetative-reproductive stages.
PoorCrop conditions are well below average. Crop yields are likely to be 10-25% below average. This is used when crops are stunted and are not likely to recover, and impact on production is likely.
FailureCrop conditions are extremely poor. Crop yields are likely to be 25% or more below average.

Drivers of Crop Conditions

DriverDefinition
WetWetter than average (includes water logging and floods).
DryDrier than average.
HotHotter than average.
ColdCooler than average or frost damage.
Extreme EventsThis is a catch-all for all other climate hazards (i.e. tropical cyclones, frost, hail, winterkill, wind damage, etc.)
Delayed OnsetLate start of season/
Pest & DiseaseDestructive insects, birds, animals, or plant disease.
Socio-economicSocial or economic factors that impact crop conditions (i.e. policy changes, agricultural subsidies, government intervention, etc.)
ConflictArmed conflict or civil unrest that is preventing the planting, working, or harvesting of the fields by the farmers.
Note: "average" refers to behavior over the 5 most recent years

Crop Season Nomenclature

In countries that contain multiple cropping seasons for the same crop, the following chart identifies the national season name associated with each crop season within the Crop Monitor.  Within the Crop Monitor for AMIS countries the larger producing season (most recent 5 years) has been assigned to the first season.
