Does the simplification of activity systems produce landscape homogenization?

Activity systems determine the land-use strategies that ultimately shape landscapes. Identifying the reasoning behind the decision making on land use strategies can help to understand how humans contribute to shaping landscapes and to design appropriate land management plans. We studied changes in land-use strategies employed by rural communities, as well as their impact on the landscape in Atzalan, Mexico. For this, we conducted interviews in households distributed throughout the municipality, documenting their activities, resources, and motivations related to land use. We also compared local perceptions of landscape change with that detected by remote sensing analysis. Our results indicate that the activity system in Atzalan features a multiplicity of economic strategies with traditional activities at their core, as well as other more intensified systems such as monocultures and pastures. However, traditional activities are largely giving way to intensified land uses, leading to landscape homogenization. The spatial and temporal distribution of the dominant land covers throughout the municipality reflects a dependency on the environmental context, social structure and land accessibility. People are aware of changes in the landscape and recognize their role in these transformations, mostly due to impacts on the forest and crop cover. Simplification of the activity system has been reflected in the homogenization of the landscape and could prevent households from maintaining diversified strategies of multiple uses of resources.
