Part of the SAGE Reference Series on Leadership; this 2-volume set tackles issues relevant to leadership in the realm of the environment and sustainability. Volume 1 of Environmental Leadership: A Reference Handbook will consider such topics as: environmental thought leadership (environmental ethics, conservation, eco-feminism, collective action and the commons and what we have termed contrarians); political leadership (the environmental challenge context for the expression of political leadership); governmental leadership (government initiatives to provide leadership in environmental management); private sector leadership (private sector leadership in environmental management as individuals, through organizations or through specific initiatives); nonprofit leadership (nonprofit sector leadership in topical areas such as conservation, advocacy, philanthropy and economic development); signaling events (events and their impact on the exercise of environmental leadership through individual, political and organizational actions); grassroots activism (profiles of individual environmental activists and considerations of how environmental leadership is exercised through activism); environmental leadership in journalism, literature and the arts; and environmental leadership in education. In Volume 2 we will cover topics that confront the particular intractable characteristics of environmental problem solving. Individual chapters will focus on how environmental leadership actions or initiatives may be applied to address specific problems in context, offering both analyses and recommendations. Overarching themes to be considered in this volume include: taking action in the face of uncertainty (mitigating climate change impacts, adapting to climate change, protecting coastal ecosystems, protecting wetlands and estuaries, preserving forest resources, protecting critical aquifers, preventing the spread of invasive species, and identifying and conserving vital global habitats); promoting international cooperation in the face of conflicting agendas (designing and implementing climate change policy, reconciling species protection and free trade, allocating scarce resources, designing sustainable fisheries, addressing global overpopulation, preventing trade in endangered species, conserving global biodiversity, and mitigating ocean debris and pollution); addressing conflicts between economic progress and environmental protection (preserving open space, redesigning cities, promoting ecotourism, redeveloping brownfields, designing transit-oriented development, confronting impacts of factory farming, preventing non-point source agricultural pollution, confronting agricultural water use, addressing the impacts of agrochemicals, designing sustainable food systems, and valuing ecosystem services); addressing complex management challenges (energy efficiency, solar energy, wind energy, hydrogen economy, alternative vehicles, solid waste disposal, hazardous waste disposal, electronic waste disposal, life cycle analysis, and waste to energy); and addressing disproportionate impacts on the poor and the weak (preventing export of developed world waste to developing countries, minimizing co-location of poverty and polluting industries, protecting the rights of indigenous peoples, preventing environmental disease, protecting children's health, providing universal access to potable water, and protecting environmental refugees). The final three chapters will examine next generation environmental leaders.
