Classification Systems

Crop Monitor for AMIS Classification System

The GEOGLAM Crop Monitor for AMIS crop classification scheme is designed to convey current crop conditions to non-agronomists in a terminology that is simple and has relatively universal meanings. Current crop conditions refer to the state of the crop during a given period in the growing season, relative to the average (i.e. typical) state over the previous five years as it relates to final expected yields. The five-year period was chosen to limit the effects of longer-term trends as a result of changes in factors such as seed varieties, and management practices. The four crop condition classes used are; exceptional, favourable, watch and poor.

Crop Condition Classes

  Condition Definition
Exceptional Conditions are much better than average* at time of reporting. This label is used only during the grain-filling through harvest stages.
Favourable Conditions range from slightly below to slightly above average at reporting time.
Watch Conditions are not far from average but there is a potential risk to final yields. 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.
Poor Crop conditions are well below average. Crop yields are likely to be 5% below average. This is only used when conditions are not likely to be able to recover, and impact on yields is likely.
Out-of-Season Crops are not currently planted or in development during this time.
No data No reliable source of data is available at this time.

* “Average” refers to the mean conditions over the most recent 5 years.

When crop conditions are identified as other-than-favourable, one or more climatic drivers are provided to indicate the cause of the abnormal crop conditions.

Drivers of Crop Conditions

  Driver Definition
Wet Wetter than average (includes water logging and floods).
Dry Drier than average.
Hot Hotter than average.
Cold Cooler than average or frost damage.
Extreme Events Catch-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 in the text.
Delayed Onset A late enough start to the season that it may impact full crop development.

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 a few adjustments. The “Poor” class threshold has been adjusted to be 10% -25% below-average due to the highly variable yields found in many early warning regions. Additionally, a “Failure” class has been added to designate when crop yields are expected to be more than 25% below-average.

Crop Condition Classes

  Condition Definition
Exceptional Conditions are much better than average* at the time of reporting. This label is used only during the grain-filling through harvest stages.
Favourable Conditions range from slightly below to slightly above-average at reporting time.
Watch Conditions are not far from average but there is a potential risk to final yields. 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.
Poor Crop conditions are well below average. Crop yields are likely to be 10-25% below-average. This is used when crops are not likely to recover, and impact on yields is likely.
Failure Crop conditions are extremely poor. Crop yields are likely to be 25% or more below average.
Out-of-Season Crops are not currently planted or in development during this time.
No data No reliable source of data is available at this time.

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.

Drivers of Crop Conditions

  Driver Definition
Wet Wetter than average (includes water logging and floods).
Dry Drier than average.
Hot Hotter than average.
Cold Cooler than average or frost damage.
Extreme Events This is a catch-all for all other climate hazards (i.e. hurricane, typhoon, frost, hail, winterkill, wind damage, etc.) When this category is used the analyst will also specify the type of extreme event in the text.
Delayed Onset A late enough start to the season that it may impact full crop development.
Pest & Disease Destructive insects, birds, animals, or plant disease.
Socio-economic Social or economic factors that impact crop conditions (i.e. policy changes, agricultural subsidies, government intervention, etc.)
Conflict Armed conflict or civil unrest that is preventing the planting, working, or harvesting of the fields by the farmers.

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 Monitors the larger producing season (most recent 5 years) has been assigned to the first season.
