‘ChitwanABM’ is an agent-based model of the Western Chitwan Valley, Nepal. The model represents a subset of the population of the Valley using a number of agent types (person, household and neighborhood agents), environmental variables (topography, land use and land cover) and social context variables.
Construction of the model is supported as part of an ongoing National Science Foundation Partnerships for International Research and Education (NSF PIRE) project (grant OISE 0729709) investigating human-environment interactions in the Western Chitwan Valley. Development of the model is continuing, and model documentation is still incomplete. As work continues, this page will be updated with more information on initializing and running the model, and on interpreting the model output.
Note: the model requires restricted access survey data from the Chitwan Valley Family Study to run. See the README file below for more information.

Two rasters are required to define the ‘world’ represented in the ChitwanABM: a digital elevation model (DEM) file and a mask file. The model can be run at 30m or 90m resolution depending on which set of world files is chosen (the 30m DEM is interpolated using cubic convolution from the 90m SRTM DEM).
The ChitwanABM agent-based model is built using the PyABM toolkit. The code of PyABM is open source (released under the GPL).
