Behind the Map:
- FAQ - AquaCrop
- AquaCrop is a crop water productivity model developed by the Land and Water Division of FAO. It simulates yield response to water of herbaceous crops, and is particularly suited to address conditions where water is a key limiting factor in crop production. AquaCrop attempts to balance accuracy, simplicity, and robustness. It uses a relatively small number of explicit and mostly-intuitive parameters and input variables requiring simple methods for their determination.
- Research Program on Climate Change, Agriculture and Food Security.
- The CCAFS is a strategic collaboration researching climate change and food security run by the CGIAR. It is from here that statistically downscaled data was retrieved from for the creation of the crop yield projections. The downscaling of Global Climate Models (GCM's) is an essential step to allow for regional studies where climate predictions are required. Most GCM's have spatial resolutions of 100m or greater, making regional data very course and likley missing large amounts of spatial variability. There are two types of downscaling, statistical and dynamic. Dynamic downscaling fits GCM outputs into regional meteorological models. These are very computational and resource heavy approaches. Statistical downscaling, the approached used in this project, use a series of equations to attempt to predict local values based off of GCM data as well as local variables such as jet stream locations.
