Land supply elasticity is a key parameter in assessing the land use response to changing environment, market conditions and policies. It reflects the fact that cultivation decisions depend on land profitability as well as on land suitability. In spite of its importance, high-resolution and aggregatable information on this elasticity is sparse. Instead, previous research has been relying on parameters that are grossly estimated and extrapolated. An improper approximation of this elasticity can significantly weaken the predictive power of an integrated assessment model in land use change studies.

This tool aims to provide land supply and transformation elasticities at any user-defined resolutions. Pre-saved in this tool is a set of grid-cell level parameters that will be used to compute these elasticities (for methodology, see attached reference papers). Users only need to upload their own mapping files indicating the area of interest and its coverage of countries. The tool would return the corresponding parameters aggregated to the indicated area. In particular, this tool provides the following functions: 

  • Compute own-price land supply elasticity and land transformation elasticity for a given area
  • Compute converted cropland areas from different non-crop covers (forest, grassland and shrublands) for a given area
  • Visualize grid-cell level land cultivation probability induced by changing land returns
  • Compare results from different simulations
