Background: Access to safe, affordable and accessible drinking water is a human right and foundational to the third and sixth World Health Organization’s Sustainable Development Goals (SDGs). Unsafe drinking water is a risk factor for chronic and enteric diseases. Both chronic kidney disease (CKD) and diarrheal disease are highly prevalent in the Lake Chapala basin, Jalisco, Mexico, suggesting disparities in factors leading to successful achievement of these two SDGs. Methods: This study aimed to assess progress towards SDG three and six in the Lake Chapala basin. Qualitative, quantitative, and geospatial data were collected between May and August of 2019 from three towns within the municipalities of Poncitlán and Chapala. Results: Ninety-nine households participated in this study. Water sampling analyses determined 81.18% of samples from water jugs (garrafones) and 70.05% of samples from tap water were contaminated with total coliform bacteria, often including E. coli. Additionally, 32% of garrafón samples and 61.9% of tap water samples had detectable levels of arsenic. Approximately 97.94% of respondents stated that they believe clean water is a human right, but 78.57% feel the Mexican government does not do enough to make this a reality. Conclusions: This mixed methods approach highlights water quality as a serious issue in communities around Lake Chapala, and demonstrates inadequate drinking water as a key hazard, potentially perpetuating the high disease burden of both CKD and enteric disease in the region.

Activists, social organizations and members of citizen collectives in Mexico and Latin America have assumed not only the fight for water and territory, but also the difficult task of interacting with experts in different scientific fields, and the challenge of placing their causes in the public space. They take the role of cultural mediators between affected people, scientists and politicians within hybrid transdisciplinary working groups. Within the framework of these groups' actions, a new current of communication of science has emerged, one that shifts its interest from encouraging involvement with scientific knowledge for its own sake, to untangling, understanding and communicating socio-environmental issues for the explicit purpose of contributing to social transformation.

World's Fairs and scientific-technological theme parks have been propitious places for the communication of science and technology through modernity. This work addresses the issue of the construction of public discourse about the future within these sites, as well as the changing role attributed to science and technology as mediators in the relationships between nature and society. In both fairs and parks, science and technology play a leading role in the construction of the discourse about the desirable and achievable future. The practices of science communication and technology have specific forms, strategies and objectives, depending on the purposes of the discourse enunciators at different historical moments. This is exemplified through two cases: the 1939 New York World's Fair and the EPCOT center in the U.S.

Este trabajo aborda la comunicación de problemáticas socioambientales en contextos urbanos, a partir de una investigación situada en la intersección entre el campo de la comunicación pública de la ciencia y el de la comunicación de lo socioambiental. El objetivo es dar cuenta de las voces y formas emergentes en las prácticas de comunicación sobre lo socioambiental, así como
