Andrew Liveris, the CEO of Dow Chemical, discusses the 120-year-old company’s ambitious sustainability agenda. He says an environmentally driven business model is good for the earth—and the bottom line. Liveris is one of the CEOs contributing to Harvard Business Review’s Future Economy Project, in which leaders detail their company’s efforts to adapt to and mitigate climate change.

In 1958, writer Rachel Carson began her exhaustive research on the effects of widespread pesticide use for her next book, Silent Spring. Over the next four years, she built up an airtight case showing how the world’s most powerful chemical companies were harming animals, plants, and people. Her effort was also a race against time, as she struggled against an aggressive form of breast cancer. In the second episode of a four-part special series on leadership, HBR Editor in Chief Adi Ignatius and Harvard Business School professor and historian Nancy Koehn trace the modern environmental movement back to Carson’s pioneering reporting and powerful prose. They discover lessons in how to strengthen your resilience, gather your energy and skills for a coming challenge, and why caretaking is an act of leadership.

Agencies and organizations deploy various strategies in response to environmental challenges, including the formulation of policy, programs, and regulations. Citizen-based environmental stewardship is increasingly seen as an innovative and important approach to improving and conserving landscape health. A new research focus on the stewardship of urban natural resources is being launched by the U.S. Forest Service in the Pacific Northwest region. Early scoping efforts are addressing various scales of human systems ranging from individuals to organizations to the entire positive "footprint" of stewardship on the land. This report addresses a fundamental need—to understand and describe civic environmental stewardship in urban settings. Stewardship has been described and defined in diverse ways within a variety of contexts, including the philosophical literature of environmentalism, agency program descriptions, and outreach by sponsoring organizations. Constructing a framework to convey the layered meanings of stewardship will help to focus and guide future research. A cognitive mapping technique was used to elicit responses to the question "What is environmental stewardship?" Semistructured interviews were conducted with representatives of nine Seattle environmental organizations, a group of practitioners who collectively represent over 100 years of experience in the field. Program planners and managers have particularly direct experiences of stewardship. Cognitive mapping enables participants to explore, then display, their particular knowledge and perceptions about an idea or activity. Analysis generated thematic, structural representations of shared concepts. Results show that the practitioners have multilayered perceptions of stewardship, from environmental improvement to community building, and from actions to outcomes. The resulting conceptual framework demonstrates the full extent of stewardship activity and meaning, which can aid stewardship sponsors to improve stewardship programs, leading to better experiences for participants and higher quality outcomes for projects and environments.

We conducted an experimental study of infection, transmission, and persistence of a nucleopolyhedrovirus (NPV) of Douglas-fir tussock moth (Orgyia pseudotsugata) to better understand mechanisms determining the efficacy of the virus when it is used as a microbial control agent. In a field experiment, we quantified infection rates of larvae exposed to either Tussock Moth Biocontrol-1, the strain currently used for control by the U.S. Forest Service, or a wild-type strain isolated from a natural population. We first allowed each pathogen to decay on experimental branches for 0, 1, or 3 days before allowing uninfected larvae to feed on the branches, and then we fit both a generalized linear model and an epidemiological model of virus transmission to the infection data. Longer decay of the NPV resulted in lower infection rates, but evidence that overall virus transmission differed between wild and pesticide isolates of NPV was weak. The short persistence time of the virus suggests that it does not last long on foliage, in turn suggesting that application of TM Biocontrol-1 must be carefully timed to ensure maximum mortality.

Prior to the existence of the National Environmental Policy Act (NEPA), Forest Service district rangers had considerable latitude to make resource management decisions and execute management plans with relatively little encumbrance by documentation and process requirements.

The Forest Service system of experimental forests and ranges (EFRs) and other sites of long-term silvicultural, watershed, and ecological research have contributed to science and natural resource management for more than a century. An important aspect of the success of EFR programs is strong collaboration between the research and land manager communities. This guide offers suggestions for effective research management partnerships based at EFRs and other long-term research sites. Keys to success include mutual understanding and respect, shared commitment to learning, and joint projects and communications programs.
