# Environmental and flooding challenges in Tabasco > Live situation record from CLSTR: https://clstr.news/situations/environmental-and-flooding-challenges-in-tabasco > Updated: 2026-09-30T18:29:05.000Z. Sources: 5. Developments: 2. Authorities in Tabasco, Mexico, have implemented various measures to address water-related environmental threats. Initial efforts focused on flood prevention due to forecasts of heavy rainfall, with the State Civil Protection Institute preparing 535 temporary shelters. Mitigation strategies included dredging rivers and the PROHTAB hydrological project, which utilizes concrete walls and embankments to reinforce vulnerable areas. As the situation evolved, focus shifted toward severe coastal erosion driven by rising sea levels. This erosion has caused the sea to advance up to 90 meters inland in specific zones, leading to what is being recognized as Mexico’s first official case of climate displacement in El Bosque. In response to these long-term coastal threats, the federal government is prioritizing natural infrastructure over concrete sea walls. Through the ‘Dunas Vivas’ project supported by UNESCO, Semarnat and Conagua are working to restore mangroves and dunes to serve as natural shields against hurricanes. ## Timeline ### 2026-09-30: Tabasco faces severe coastal erosion and climate displacement Tabasco faces severe coastal erosion and climate displacement.
