Data used in these tutorials

During the tutorials, we will use a dataset containing social and ecological variables associated with agricultural systems (coffee production). The variables are classified into four main groups:

Analysis of this data can contribute to the development of more sustainable and diversified agroecosystems. The list of variables with their descriptions and units is provided in Table 1. The data file is available on Brightspace.
