Overview

• Environmental agencies are conducting diagnostics on lagoons and canals to design interventions, including local infiltration works and a possible treatment plant.
• Officials flagged chinampa subsidence linked to groundwater overextraction near Canal de Chalco and roughly 500 irregular sewage discharges as urgent problems.
• The plan targets chinampa communities in Xochimilco and Tláhuac—San Gregorio Atlapulco, San Luis Tlaxialtemalco, Santiago Tulyehualco and San Pedro—and will incorporate residents’ proposals through upcoming dialogues.
• The government tied the recovery to local livelihoods via Altépetl supports and Yolotl Anáhuac upgrades, aiming to lift native maize output from about 3,000 tonnes by up to 15% next year.
• Designs expected in the coming months are intended for submission to the 2026 city budget so investments can begin next year, including measures to secure potable water for local use.
