Pursuing sustainability : a guide to the science and practice
\"Sustainability is a global imperative and a scientific challenge like no other. This concise guide provides students and practitioners with a strategic framework for linking knowledge with action in the pursuit of sustainable development, and serves as an invaluable companion to more narrowly focused courses dealing with sustainability in particular sectors such as energy, food, water, and housing, or in particular regions of the world. Written by leading experts, Pursuing Sustainability shows how more inclusive and interdisciplinary approaches and systems perspectives can help you achieve your sustainability objectives. It stresses the need for understanding how capital assets are linked to sustainability goals through the complex adaptive dynamics of social-environmental systems, how committed people can use governance processes to alter those dynamics, and how successful interventions can be shaped through collaborations among researchers and practitioners on the ground. The ideal textbook for undergraduate and graduate students and an invaluable resource for anyone working in this fast-growing field, Pursuing Sustainability also features case studies, a glossary, and suggestions for further reading. Provides a strategic framework for linking knowledge with action Draws on the latest cutting-edge science and practices. Serves as the ideal companion text to more narrowly focused courses. Utilizes interdisciplinary approaches and systems perspectives. Illustrates concepts with a core set of case studies used throughout the book. Written by world authorities on sustainability. An online illustration package is available to professors\"-- Provided by publisher.

Exercise induces cerebral VEGF and angiogenesis via the lactate receptor HCAR1
Physical exercise can improve brain function and delay neurodegeneration; however, the initial signal from muscle to brain is unknown. Here we show that the lactate receptor (HCAR1) is highly enriched in pial fibroblast-like cells that line the vessels supplying blood to the brain, and in pericyte-like cells along intracerebral microvessels. Activation of HCAR1 enhances cerebral vascular endothelial growth factor A (VEGFA) and cerebral angiogenesis. High-intensity interval exercise (5 days weekly for 7 weeks), as well as L-lactate subcutaneous injection that leads to an increase in blood lactate levels similar to exercise, increases brain VEGFA protein and capillary density in wild-type mice, but not in knockout mice lacking HCAR1. In contrast, skeletal muscle shows no vascular HCAR1 expression and no HCAR1-dependent change in vascularization induced by exercise or lactate. Thus, we demonstrate that a substance released by exercising skeletal muscle induces supportive effects in brain through an identified receptor.
Physical exercise promotes brain angiogenesis through an unknown signalling cascade. Morland
et al
. identify the elusive muscle-brain communication and show that lactate produced by muscle activity binds to its receptor HCAR1 in brain vessel-surrounding cells, stimulating VEGF production and brain angiogenesis.

Gender quotas increase the equality and effectiveness of climate policy interventions
Interventions to reduce greenhouse gas emissions strive to promote gender balance so that men and women have equal rights to participate in, and benefit from, decision-making about such interventions. One conventional way to achieve gender balance is to introduce gender quotas. Here we show that gender quotas make interventions more effective and lead to more equal sharing of intervention benefits. We conducted a randomized ‘lab’-in-the-field experiment in which 440 forest users from Indonesia, Peru and Tanzania made decisions about extraction and conservation in a forest common. We randomly assigned a gender quota to half of the participating groups, requiring that at least 50% of group members were women. Groups with the gender quota conserved more trees as a response to a ‘payment for ecosystem services’ intervention and shared the payment more equally. We attribute this effect to the gender composition of the group, not the presence of female leaders.Decision-making structures in forest-user communities often exclude women. This lab-in-field experiment shows that groups in which at least 50% of members were women conserved more trees, and distributed benefits more equally, in a payment for ecosystem services intervention.

Voluntary leadership and the emergence of institutions for self-governance
Strong local institutions are important for the successful governance of common-pool resources (CPRs), but why do such institutions emerge in the first place and why do they sometimes not emerge at all? We argue that voluntary local leaders play an important role in the initiation of self-governance institutions because such leaders can directly affect local users’ perceived costs and benefits associated with self-rule. Drawing on recent work on leadership in organizational behavior, we propose that voluntary leaders can facilitate a cooperative process of local rule creation by exhibiting unselfish behavior and leading by example. We posit that such forms of leadership are particularly important when resource users are weakly motivated to act collectively, such as when confronted with “creeping” environmental problems. We test these ideas by using observations from a laboratory-in-the-field experiment with 128 users of forest commons in Bolivia and Uganda. We find that participants’ agreement to create new rules was significantly stronger in group rounds where voluntary, unselfish leaders were present. We show that unselfish leadership actions make the biggest difference for rule creation under high levels of uncertainty, such as when the resource is in subtle decline and intragroup communication sparse.

Collective forest land rights facilitate cooperative behavior
The introduction of formal collective property rights to forest lands appears to have improved both environmental and economic outcomes, but there is limited evidence on how these reforms affect cooperative behavior among local resource users. We propose that when national governments issue collective land rights, they strengthen the collective psychological ownership among coowners and produce increased levels of cooperative behavior. Analyzing data from 213 forest user groups in 10 countries, and a framed field experiment in a subset of sites, we find that collective land titling is associated with significantly higher levels of cooperative behavior including increased levels of trust, more frequent interpersonal interactions related to both forestry and nonforestry activities, more self‐governing institutions, and greater equality in resource extraction patterns.

Decentralization can help reduce deforestation when user groups engage with local government
Policy makers around the world tout decentralization as an effective tool in the governance of natural resources. Despite the popularity of these reforms, there is limited scientific evidence on the environmental effects of decentralization, especially in tropical biomes. This study presents evidence on the institutional conditions under which decentralization is likely to be successful in sustaining forests. We draw on common-pool resource theory to argue that the environmental impact of decentralization hinges on the ability of reforms to engage local forest users in the governance of forests. Using matching techniques, we analyze longitudinal field observations on both social and biophysical characteristics in a large number of local government territories in Bolivia (a country with a decentralized forestry policy) and Peru (a country with a much more centralized forestry policy). We find that territories with a decentralized forest governance structure have more stable forest cover, but only when local forest user groups actively engage with the local government officials. We provide evidence in support of a possible causal process behind these results: When user groups engage with the decentralized units, it creates a more enabling environment for effective local governance of forests, including more local government-led forest governance activities, fora for the resolution of forest-related conflicts, intermunicipal cooperation in the forestry sector, and stronger technical capabilities of the local government staff.

Getting citizens to conserve water: A comparison of crisis responses in Bogota and Mexico City
How can global megacities respond to increased threats from natural hazards? Looking at hazard events that produced drinking water crises in Bogota, Colombia, and Mexico City, Mexico, we compare these cities’ efforts to decrease potable water consumption. We ask how and why the socioeconomic and biophysical contexts shape city policymakers’ responses to water crises and consider the immediate and lasting impacts of technical and behavioral interventions. Leveraging our 2 case studies in Latin America, we identify how the unique policy contexts affected the interventions used and helped determine their outcomes. Four factors are identified as particularly relevant as follows: the differential roles of scientific and technical perspectives in each context, the role of ideology, the complexity of the environmental policy problems in each setting, and the varied roles of policy entrepreneurs in Bogota and Mexico City.

What Motivates Local Governments to Invest in Critical Infrastructure? Lessons from Chile
In this study, we identify institutional factors and processes that foster local government decisions about disaster risk reduction, especially critical infrastructure investments and maintenance. We propose that municipal institutional capacities, organization, leadership, and multilevel governance will affect critical infrastructure investments by local governments. To examine these ideas, we employ qualitative analysis to compare two representative medium–sized cities in Chile. Our results suggest that there are two main institutional factors that constitute the foundation for improvements in critical infrastructure in Chile: municipal institutional context and the local administration’s links with decision makers at higher levels of governance. These results imply that future interventions to strengthen local government efforts for disaster risk reduction in terms of critical infrastructures would benefit from a pre-intervention diagnosis of the target location’s existing institutional context and linkages with external governance actors.

Analyzing Decentralized Resource Regimes from a Polycentric Perspective
This article seeks to shed new light on the study of decentralized natural resource governance by applying institutional theories of polycentricity-the relationships among multiple authorities with overlapping jurisdictions. The emphasis on multi-level dynamics has not penetrated empirical studies of environmental policy reforms in nonindustrial countries. On the contrary, many of today's decentralization proponents seem to be infatuated with the local sphere, expecting that local actors are always able and willing to govern their natural resources effectively. Existing studies in this area often focus exclusively on characteristics and performance of local institutions. While we certainly do not deny the importance of local institutions, we argue that institutional arrangements operating at other governance scales-such as national government agencies, international organizations, NGOs at multiple scales, and private associations-also often have critical roles to play in natural resource governance regimes, including self-organized regimes.

Collective PES Contracts Can Motivate Institutional Creation to Conserve Forests: Experimental Evidence
ABSTRACT
Incentives are a widely used tool for addressing deforestation and are often implemented as collective contracts. Local institutions are crucial to the solution of collective action problems associated with forest conservation, but we still have little knowledge of how to encourage institutional creation through policy. Since collective contracts do not eliminate freeriding incentives, we argue that their success hinges on their ability to stimulate the creation of institutions for collective action. To test these ideas, we analyze data from an incentivized lab‐in‐the‐field experimental collective action game played with natural resource users in four developing countries. The experiment simulates management of a common forest, and groups were randomly assigned to a conservation incentive payment condition. We observe how much group members attempt to coordinate on the creation of institutional rules and find experimental evidence that an external incentive program can stimulate the endogenous creation of informal institutions.
