Water planners and policy analysts need to pay closer attention to the behavioral aspects of water use, including the use of nonprice measures such as norms, public communications, and intrinsic motivations. Empirical research has shown that people are motivated by normative as well as economic incentives when it comes to water. In fact, this research finds that after exposure to feedback about water use, adding an economic incentive (rebate) for reducing water use holds no additional power. In other cases, nonprice measures can be a way to increase the salience, and subsequently, effectiveness of any adopted pricing mechanisms. We review these empirical findings and locate them within more general literature on normative incentives for behavioral change. Given increasing water scarcity and decreasing water security in cities, policy planners need to make more room for normative incentives when designing rules for proenvironmental behavior.

The relationship between environment and health is part of the history of medicine and has always been important to any study of human health and to public-health interventions. In Latin America many health improvements are related to environmental interventions, such as the provision of better water and sanitation services. Latin America’s development, industrialization, and sweeping urbanization have brought many improvements to the well-being of its populations; they have also inaugurated new societies, with new patterns of consumption. The region’s basic environmental-health interventions have needed to be updated and upgraded to include disciplines such as toxicology, environmental epidemiology, environmental engineering, and many others. Multidisciplinary and inter-sector approaches are paramount to understanding new profiles of health and well-being, and to promoting effective public-health interventions. The new social, economic, labor, and consumption aspects of modern Latin American society have become more and more relevant to understanding the complex interactions in the region’s social, biological, and physical environment, which are essential to explaining some of the emerging and re-emerging public-health problems. Environmental health, as concept and as intervention, is simple and easily understood, but no longer sufficient to achieve the levels of health and well-being expected and required by these new realities. Many global changes such as climate change, biodiversity loss, and mass migrations has been identified as main cause of ill health and are at the center of the sustainable development challenges in general, and many are critical and specific public health. To face this development, other frameworks have emerged, such as planetary health and environmental and social determinants of health. Public health remains central to some, such as the improved environmental-health agenda, while others assign public health a relative position in a variety of overarching frameworks.
Street science is the processes used by community residents to understand, document, and take action to address the environmental health issues they are experiencing. Street science is an increasingly essential process in global urban health, as more and more people live in complex environments where physical and social inequalities create cumulative disease burdens. Street science builds on a long tradition of critical public health that values local knowledge, participatory action research, and community-driven science, sometimes referred to as “citizen science.” Street scientists often partner with professional scientists, but science from the street does not necessarily fit into professional models, variables or other standards of positivist data. Street science is not one method, but rather an approach where residents are equally expert as professional scientists, and together they co-produce evidence for action. In this way, street science challenges conventional notions in global health and urban planning, which tend to divorce technical issues from their social setting and discourage a plurality of participants from engaging in everything from problem setting to decision-making. Street science does not romanticize local or community knowledge as always more accurate or superior to other ways of knowing and doing, but it also recognizes that local knowledge acts as an oppositional discourse that gives voice to the often silent suffering of disadvantaged people. At its best, street science can offer a framework for a new urban health science that incorporates community knowledge and expertise to ensure our cities and communities promote what is already working, confront the inequities experienced by the poor and vulnerable, and use this evidence to transform the physical and social conditions where people live, learn, work, and play.

A strong social gradient in the experience of health means that a person’s health tends to reflect social position. There is strong evidence that average health outcomes in a country tend to be poorer when income inequality is greater. Consequently, public health policy is influenced by a country’s economic situation. Adopting principles in the Helsinki Statement on Health in All Policies, this means governments should pay attention to the public health implications of its economic policies, moving beyond simple analyses of how policy might support growth in gross domestic product. Since 2009, a global movement has aimed to shift the emphasis of economic policy evaluation from measuring economic production to measuring people’s well-being. This approach is known as well-being economics. Many countries have engaged with citizens to create their own national well-being framework of statistical indicators. Some countries have passed legislation or designed new institutions to focus specific policy areas on promoting the well-being of current and future generations. A small number of countries are attempting to embed well-being in their core economic policies. Further policy work and research are required for the vision of a well-being economy to be realized.
