The Mexican Caribbean is part of the Mesoamerican Barrier Reef System, considered the second largest reef system globally. This system, as well as inland aquatic ecosystems, are at risk of contamination due to the intensive use of sunscreen by the tourists who visit the Riviera Maya each year. At present, the regulation and management of sunscreens...
Resumen La falta de acceso a fuentes de agua segura es un problema en el Caribe Mexicano, particularmen-te en comunidades con irregularidad en servicios. Ante esto, la captación de agua de lluvia (CALL) podría representar una alternativa para satisfacer necesidades básicas. Sin embargo, los esquemas de implementación a menudo son verticales y jerár...
Mexico faces multiple water quality challenges, both in terms of the water supplied to the population as well as surface and underground water sources. Problems with drinking water supply affect the population in diverse ways, from associated health risks to high levels of intermittency in service to the poor perception of the quality of piped wate...
Sunscreens have spread widely into aquatic systems over the last 18 years in Quintana Roo, Mexico. This contamination is caused by intensive use as a result of leisure activities, as sunbathers apply the substances intensively (up to 83.75% of tourists and locals). Moreover, 25% of the compounds are mainly released into the water through topical pr...
Since 2011, tourism to Mexico’s Yucatán Peninsula has been heavily impacted by large masses of sargassum seaweed washing up on the beaches, with the largest seaweed event occurring in 2019. Seaweed deters beach tourism, potentially shifting tourism inland towards other activities such as swimming in cenotes (sinkholes). Our mixed methods study comb...
Tourist growth in Quintana Roo, Mexico has brought with it an increase of pollution by sunscreens to aquatic ecosystems, which represents an environmental risk because of the chemical components of sunscreens that can negatively affect human health and aquatic ecosystems. However, the magnitude of pollution in aquatic environments is unknown. Conse...
En este boletín de políticas públicas se aborda la gestión del agua en los municipios del estado de Jalisco a partir del análisis de datos oficiales y de la realización de entrevistas y encuestas en cuatro municipios de cuatro regiones del estado: El Salto, Gómez Farías, San Juan de los Lagos y Villa Guerrero.

La migración por jubilación ocurre en varios países de Centroamérica, en el norte de África y en la Unión Europea, en donde los inmigrantes jubilados ocupan la región mediterránea (Lizárraga-Morales, 2008). En México, esa migración se presenta como un turismo residencial rural. En los últimos veinte años y tras las modi ca...

Migration of foreign retirees in Mexico has increased, especially in Los Cabos, where settlements trailer type are increasing and are moving into rural coastal areas of high ecological value, without the knowledge of impacts that may result. Thus the aim of this paper is to contribute to the understanding of this type of settlement, by documenting...
During 2004 the spatial distribution of total Hg in sediments from Todos Santos Bay, Baja California, México was studied to evaluate the degree of environmental impact in this bay. The results showed low concentrations and no Hg enrichment at any site. These findings suggest natural levels of Hg in the water of Todos Santos Bay. The regional distri...
An evaluation was made of the distribution and enrichment of Hg in surface sediments collected in August 1998 at 37 stations along the northwest coast of Baja California (NCBC). Mercury was analyzed by cold-vapour atomic absorption spectrophotometry. The percentages of mud (<63 μm) and organic matter were also measured. Mercury concentrations showe...
