Since the late 1970s, the term “colonias” (in English) has described low‐income, peri‐urban, and rural subdivisions north of the U.S.‐Mexico border. These communities are in arid and semi‐arid regions—now in a megadrought—and tend to have limited basic infrastructure, including community water service and sanitation. Recent scholarship has demonstrated how colonias residents experience unjust and inequitable dynamics that produce water insecurity in the Global North. In this review, we explain why U.S. colonias are an important example for theorizing water insecurity in the United States and beyond in the Global North. Tracing the history of water infrastructure development in U.S. colonias, we show how colonias are legally and socially defined by water insecurity. We draw on the published literature to discuss key factors that produce water insecurity in U.S. colonias: political exclusion, municipal underbounding, and failures in water quality monitoring. We show that water insecurity had led to negative outcomes—including poor water access, risks to physical health, and mental ill‐health—in U.S. colonias. We present four possible approaches to improving water security in U.S. colonias: (1) soft paths & social infrastructure for water delivery, (2) decentralized water treatment approaches, such as point‐of‐use, point‐of‐entry, and fit‐for‐purpose systems; (3) informality, including infrastructural, economic, and socio‐cultural innovations; and (4) political, policy, and law innovations and reforms. At the same time, we reflect seriously on how water security can be ethically achieved in partnership and aligning with the visions of U.S. colonias residents themselves.This article is categorized under: Human Water > Water Governance Engineering Water > Water, Health, and Sanitation

Community-based participant-observation purposefully combines participant-observation and community-based participatory research. While participant-observation is the core method of ethnography and foundational to cultural anthropology, community-based participatory research initially emerged from health and related applied sciences to align researchers’ and communities’ agendas through focused collaboration. Participant-observation and community-based participatory research have different scholarly origins and norms but are united in centering communities’ understandings on their terms. Combining the strengths of both, we provide a step-by-step explanation of community-based participant-observation, with examples from a study of water insecurity in colonias north of the U.S.–Mexico border. Using community-based participant-observation, researchers can facilitate the co-production of knowledge and community benefit by analyzing high-quality data that inform theory building and basic research.

Puerto Rico’s residents were left without water services for up to nine months in the wake of hurricanes Irma and María (2017). Further, it was clear that there were no viable plans for addressing water provision gaps in anticipation of future hazards. In response, Puerto Ricans initiated autogestión, a strategy to secure survival through self-provisioning. Utilizing mixed methods, we reveal two different emergent forms of autogestión water self-provision in three differently serviced Puerto Rican communities. These provide an informed reflection on the trade-offs and pitfalls of reliance on autogestión for water security in the wake of disaster.

This paper introduces the concept of “Participatory Convergence” as a framework to meet grand social-ecological challenges. Participatory Convergence combines the principles of Convergence Research with Participatory Action Research (PAR), offering a novel approach to tackling complex societal problems. Convergence Research seeks to foster high-level integration between diverse disciplines to address multifaceted issues, emphasizing systems thinking and solutions orientation; however, existing literature falls short in providing practical models for the deep integration of diverse disciplines, community partners, and community members. This paper aims to bridge these gaps by integrating Convergence Research with PAR. We illustrate the application of Participatory Convergence with a case study: the “Action for Water Equity” project, focusing on water challenges faced by communities in U.S. colonias along the U.S.–Mexico border. The Action for Water Equity project is a practical example of how Participatory Convergence can be applied to tackle pressing challenges while embracing diversity, inclusivity, and adaptability. This approach holds the potential to facilitate comprehensive solutions for global challenges and foster meaningful change through interdisciplinary collaboration, community engagement, and a commitment to sustainability and equity.
