title: Data and Visualization Code for "AIM-ALPHA v1.0: A partial equilibrium model of global agriculture and land use at basin-level resolution"

description: This Zenodo repository provides the model simulation results, along with the R code used for generating the figures in the manuscript "AIM-ALPHA v1.0: A partial equilibrium model of global agriculture and land use at basin-level resolution".

This repository includes R code for processing data and generating the figures.After placing the required datasets into the data/ directory, you can reproduce the outputs by either:

1. Opening RStudio and running prog/Visualization.R  or

2. Running the shell script run.sh

The generated figures will be saved in the /output/plot/ directory.

Datasets:

To run the scripts, you will need to download the required data from the SSP Public Database (Version 2.0), available at:

    https://tntcat.iiasa.ac.at/SspDb

Please place the downloaded SSP data into the "data" directory of this repositorybefore running the code. The SSP database is provided by IIASA under its own terms of use, and therefore the original data cannot be redistributed here.

This repository also contains several external datasets used in the analysis. These datasets are provided in processed and reformatted versions based on the original sources listed below:
