A growing body of empirical evidence is revealing the value of nature experience for mental health. With rapid urbanization and declines in human contact with nature globally, crucial decisions must be made about how to preserve and enhance opportunities for nature experience. Here, we first provide points of consensus across the natural, social, and health sciences on the impacts of nature experience on cognitive functioning, emotional well-being, and other dimensions of mental health. We then show how ecosystem service assessments can be expanded to include mental health, and provide a heuristic, conceptual model for doing so.

Background:At a time of increasing disconnectedness from nature, scientific interest in the potential health benefits of nature contact has grown. Research in recent decades has yielded substantial evidence, but large gaps remain in our understanding.Objectives:We propose a research agenda on nature contact and health, identifying principal domains of research and key questions that, if answered, would provide the basis for evidence-based public health interventions.Discussion:We identify research questions in seven domains: a) mechanistic biomedical studies; b) exposure science; c) epidemiology of health benefits; d) diversity and equity considerations; e) technological nature; f) economic and policy studies; and g) implementation science.Conclusions:Nature contact may offer a range of human health benefits. Although much evidence is already available, much remains unknown. A robust research effort, guided by a focus on key unanswered questions, has the potential to yield high-impact, consequential public health insights. https://doi.org/10.1289/EHP1663

Cochran, Bobby and Charles Logue, 2011. A Watershed Approach to Improve Water Quality: Case Study of Clean Water Services’ Tualatin River Program. Journal of the American Water Resources Association (JAWRA) 47(1):29‐38. DOI: 10.1111/j.1752‐1688.2010.00491.x Abstract:  Over the last five years, Clean Water Services developed and implemented a program to offset thermal load discharged from its wastewater facilities to the Tualatin River by planting trees to shade streams and augmenting summertime instream flows. The program has overcome challenges facing many of the nation’s water quality trading programs to not only gain consensus on the frameworks needed to authorize trading, but also provide a broad range of ecosystem services. This paper compares the Tualatin case study with some of the commonly cited factors of successful trading programs.

This article takes a first step toward analyzing the characteristics of a cross-policy, state-wide collaborative system. Specifically, using data from the Atlas of Collaboration project, we offer a big-picture analysis of how over 200 externally directed collaborative governance regimes (CGRs) are operationalized in a state-level collaborative system consisting of 13 collaborative platforms operating across five policy areas (economic development, education, health, natural resources, public safety) in Oregon. We focus on three attributes—geographic scope, collaborative size, and collaborative characteristics—aggregated at the system level across CGRs, as well as across collaborative platforms and policy areas. The descriptive findings reveal that collaborative efforts are geographically dispersed across the state, involve thousands of participants representing organizations from the public, private, and nonprofit sectors, and vary across multiple characteristics, such as organizational form, lead organization, funding model, structural roles, staffing, and extent of face-to-face dialogue. These findings lay the groundwork for future theoretical development and empirical research.
