The Valley of Mexico is a high-altitude basin ringed by volcanic mountains, stewarded for centuries by the Nahua and Otomi peoples whose lineage on this land carries an unbroken practice of agricultural cosmology, ceremonial calendar, and urban-rural cohabitation. The bioregion holds one of the densest regenerative cultural infrastructures in the Americas: Huerto Roma Verde and the Roma Norte and Coyoacán neighborhoods, the Xochimilco chinampa system, agroecology collectives across the valley, and the indigenous-led food-sovereignty networks that compose the everyday ground.
The city and the surrounding ecology already practice the cohabitation the Protocol invites. The dry season and the rainy season set the rhythm; ceremony tracks both. The valley has held population centers continuously for more than seven hundred years, and the modern city has not erased the older grammar so much as layered itself on top of it. The Protocol enters where that grammar is still legible.
