An agent-based model of the Chitwan Valley, Nepal

Project description

Model Description

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 in progress, and model documentation is still incomplete.

See the chitwanabm website for more information, past releases, publications, and recent presentations.

Getting the Code

Stable releases of chitwanabm are available from the Python Package Index (PyPI).

The latest version of the code (unstable) is available as a zipped snapshot from Github.

The chitwanabm is based off of extensive work done as a part of the Chitwan Valley Family Study. The Chitwan Valley Family Study dataset can be cited as:
