Water struggles and contested use: A capabilities assessment of household water security in marginalized communities.

In this study, we apply a capabilities approach to analyze a water consolidation project and water security outcomes following a severe drought in East Porterville, California. By combining hydro-social theory with the capabilities approach, we provide a holistic approach to household water security that is historically situated, considers residents' needs, and accounts for areas of life beyond hydration and domestic use. In addition, we offer a critical analysis of water system consolidation, a process of combining water systems physically and/or managerially as a solution to water insecurity in small towns. Drawing on interviews with residents, local experts, and government officials as well as archival research and participant observation, we find that the water consolidation project has mixed results for the East Porterville community, with beneficial, limiting, and contested effects on residents' social, cultural, and economic life. Although residents now have a consistent source of water in their homes, they find themselves limited in their ability to use water for drinking and cultural and economic purposes. Water negotiations and contestations also affected property values, independence, and livability. Through this empirical application of the capabilities approach, we demonstrate the need to expand the concept of water security and consolidation outcomes through needs-based perspectives. Furthermore, we show how the coupling of capabilities approach with a hydro-social framework provides descriptive, analytical, and explanatory tools for understanding and addressing household water security.

Predicting why people engage in pro-sustainable behaviors in Portland Oregon: The role of environmental self-identity, personal norm, and socio-demographics.

This study aims to identify factors influencing people's participation in frequent and effective pro-sustainable behaviors (PSB) in Portland, Oregon, using value-belief-norm theory and a modified value-identity-personal-norm (VIP) model. Drawing from a resident survey (n = 484) and applying a series of regression and mediation analyses, we tested the power of the VIP model in our sample to examine the influence of values, environmental self-identity, and personal norms on PSB while adjusting for socio-demographic factors. Our study revealed participants who held altruistic values (i.e., cared for the community, valued diversity and gender equality, and made decisions based on cooperation) had stronger environmental self-identity characterized by a belief that reflects biocentrism, ecofeminism, ecospirituality, or deep ecology. These identities were significantly associated with participation in more effective PSB after adjusting for personal norms. Participants with egoistic values had stronger anthropocentric identity and weaker personal norms which translated into lower participation in more effective PSB. Also, education increased PSB, with master's degree holders participating more than other groups. Overall, values, environmental self-identity, and higher education predicted participation in effective PSB. Our refined theoretical model is, therefore, promising for assessing multiple PSB at once, especially those that significantly reduce carbon footprint on the planet.

Why climate migration is not managed retreat: Six justifications.

This perspective piece makes a case for a more rigorous treatment of managed retreat as a politically, legally, and economically distinct type of relocation that is separate from climate migration. We argue that the use of both concepts interchangeably obfuscates the problems around climate-induced mobilities and contributes to the inconsistencies in policy, plans, and actions taken by governments and organizations tasked with addressing them. This call for a disentanglement is not solely an academic exercise aimed at conceptual clarity, but an effort targeted at incentivizing researchers, practitioners, journalists, and advocates working on both issues to better serve their constituencies through alliance formation, resource mobilization, and the establishment of institutional pathways to climate justice. We offer a critical understanding of the distinctions between climate migration and managed retreat grounded in six orienting propositions. They include differential: causal mechanisms, legal protections, rights regimes and funding structures, discursive effects, implications for land use, and exposure to risks. We provide empirical examples from existing literature to contextualize our propositions while calling for a transformative justice approach to addressing both issues.

Social media analysis reveals environmental injustices in Philadelphia urban parks.

The United Nations Sustainable Development Goal (SDG) target 11.7 calls for access to safe and inclusive green spaces for all communities. Yet, historical residential segregation in the USA has resulted in poor quality urban parks near neighborhoods with primarily disadvantaged socioeconomic status groups, and an extensive park system that addresses the needs of primarily White middle-class residents. Here we center the voices of historically marginalized urban residents by using Natural Language Processing and Geographic Information Science to analyze a large dataset (n = 143,913) of Google Map reviews from 2011 to 2022 across 285 parks in the City of Philadelphia, USA. We find that parks in neighborhoods with a high number of residents from historically disadvantaged demographic groups are likely to receive lower scores on Google Maps. Physical characteristics of these parks based on aerial and satellite images and ancillary data corroborate the public perception of park quality. Topic modeling of park reviews reveal that the diverse environmental justice needs of historically marginalized communities must be met to reduce the uneven park quality-a goal in line with achieving SDG 11 by 2030.

The effects on public health of climate change adaptation responses: a systematic review of evidence from low- and middle-income countries.

Climate change adaptation responses are being developed and delivered in many parts of the world in the absence of detailed knowledge of their effects on public health. Here we present the results of a systematic review of peer-reviewed literature reporting the effects on health of climate change adaptation responses in low- and middle-income countries (LMICs). The review used the 'Global Adaptation Mapping Initiative' database (comprising 1682 publications related to climate change adaptation responses) that was constructed through systematic literature searches in Scopus, Web of Science and Google Scholar (2013-2020). For this study, further screening was performed to identify studies from LMICs reporting the effects on human health of climate change adaptation responses. Studies were categorised by study design and data were extracted on geographic region, population under investigation, type of adaptation response and reported health effects. The review identified 99 studies (1117 reported outcomes), reporting evidence from 66 LMICs. Only two studies were ex ante formal evaluations of climate change adaptation responses. Papers reported adaptation responses related to flooding, rainfall, drought and extreme heat, predominantly through behaviour change, and infrastructural and technological improvements. Reported (direct and intermediate) health outcomes included reduction in infectious disease incidence, improved access to water/sanitation and improved food security. All-cause mortality was rarely reported, and no papers were identified reporting on maternal and child health. Reported maladaptations were predominantly related to widening of inequalities and unforeseen co-harms. Reporting and publication-bias seems likely with only 3.5% of all 1117 health outcomes reported to be negative. Our review identified some evidence that climate change adaptation responses may have benefits for human health but the overall paucity of evidence is concerning and represents a major missed opportunity for learning. There is an urgent need for greater focus on the funding, design, evaluation and standardised reporting of the effects on health of climate change adaptation responses to enable evidence-based policy action.
