Which environmental risk increases with maize monoculture farming on pre-Columbian chinampa systems?

💡 Explanation

When maize monoculture is practiced, the lack of genetic diversity amplifies vulnerability to disease, because a single pathogen can devastate the entire crop. Therefore the risk of blight increases, rather than reduced filtration, stone depletion, or increased runoff; each requires different agricultural management factors or environmental changes.
