The Nahua communities in the Central Highlands of La Montaña of Guerrero region have a ritualagricultural cycle closely related to seasonality, environmental processes, agriculture, and landscape. The most important celebrations in the region are those asking for a good rainy season, for the rain to end, and to thank for the harvest. Building upon the ethnoecological framework, this study explores ritual-agricultural practices, the water realities these practices make, and their implications in water conservation and communitarian management.
