Editing Crop yield gap index (section)

== Signal Definition ==
The crop yield gap index quantifies the relative difference between realized crop production and the attainable production level achievable under comparable agronomic and environmental conditions. It is expressed as an index value, typically normalized to represent the proportion or percentage by which actual yields fall short of potential yields. This index captures the magnitude of yield deficits attributable to non-climatic factors such as management practices, pest and disease impacts, and soil fertility constraints, isolating these from inherent environmental limitations.
