Abstract –In 2025 per capita water availability will decrease to 150 gallons per day in the best for the communities near any aquifer.The water situation will worsen as the population density and the shortage becomes acute exacerbate unsafe, leading cause of death in children with hydrotransmitted diseases.Such a scenario requires theoretical reconceptualization enabling public policies, environmental agendas, public opinion and social work.In this sense, the objective of this paper is to present water situation to conceptualize from the thought of Enrique Leff (2002, 2004, 2008) and analyze their transformation into public agenda.Understanding the relationship between water situations, public opinion, political initiatives, scientific diagnoses, technohydrological innovations and media coverage will be critical for social work professionals in the near future. Keywords –Sustainability, Access, Knowledge and Rationality Agenda. ; ESPECIFICAÇÃO DE UM MODELO PARA ESTUDO DA SUSTENTABILIDADE DO TRABALHO SOCIAL Resumo - Em 2025, a disponibilidade de água per capita diminuirá para 150 galões por dia, no melhor para as comunidades próximas a qualquer aqüífero. A situação da água vai piorar à medida que a densidade populacional e a escassez se agravam de forma aguda e insegura, principal causa de morte em crianças com doenças hidrotransmitidas. Tal cenário requer uma reconceituação teórica viabilizando políticas públicas, agendas ambientais, opinião pública e trabalho social. Nesse sentido, o objetivo deste artigo é apresentar a situação da água para conceituar a partir do pensamento de Enrique Leff (2002, 2004, 2008) e analisar sua transformação em agenda pública. Compreender a relação entre situações hídricas, opinião pública, iniciativas políticas, diagnósticos científicos, inovações tecnohidrológicas e cobertura da mídia será fundamental para os profissionais do serviço social em um futuro próximo.

This article examines how artists have engaged with the issue of air pollution in Beijing, where poor air quality has become a serious public health matter. Artists have utilized various mediums including performance art, photography, and painting to represent smog. Through generating media and online attention this work has contributed to a relatively vibrant "green public sphere" (Yang and Calhoun, 2007) of air pollution discourse. In contrast to much resistance in China that relies upon making specific claims to government officials, artistic expression bypasses the authorities and appeals instead to public opinion. Artists utilize ambiguity to portray air pollution in novel ways that subtly question the structures that produce and sustain it. In this way, artists can challenge popular perceptions of smog and raise public awareness, thus intensifying support for policies that tackle smog. Yet art can also embody deep frustration at the powerlessness that artists, and the public more widely, experience when confronted by severe air pollution. Art therefore serves both as a form of activism and as an expression of curtailed agency in a politically restrictive environment.
