History of the Environment and Ecological Science
(F&ES 80032 /F&ES823)
Arvid Nelson


In this seminar, students explore the tools of historical research and analysis and develop their writing skills. Students' work centers on practical applications of historical research, data analysis, and narrative so that students gain new power in problem analysis and narrative. After focusing on landscape, forest, and farm history from the earliest records, the seminar folds in the history of ecosystem analysis, forest science, and biologists' and ecologists' influence on political and economic theory. The dynamics of historical change in natural systems in response to management and ecological constraints tells more than the story of how the natural world emerges; it deepens our understanding of political and economic history and of human culture. The ecological orientation afforded by environmental history leads to more successful and ethical policymaking through its emphasis on context, on emergent processes, and on the central role of individuals and communities in environmental, political, and cultural system dynamics.


Leaves, Livelihoods, and Landscapes: Ecology, Socio-Economics, and Politics of Development across Borneo
(F&ES 80166 )
Lisa Curran
Amity Doolittle


Borneo has occupied a space of exoticism in our collective imagination ever since colonial explorers returned to the metropolis with stories of headhunters and the "wild man of the forest." More contemporary images of Borneo include massive forest fires and violent ethnic wars. Despite these images of "primitive" and wild jungles, the past two decades have brought unprecedented socio-economic and environmental change to Borneo. This interdisciplinary course explores the historical, bio-geographical, political, and socio-economic context of anthropogenic and natural change across the Bornean landscape. Each week students are introduced to basic concepts from the ecological and social sciences. These concepts are then applied to specific case studies in Borneo. We examine the interrelated issues of forest conversion, local livelihood practices, resource distribution and availability, and extractive industries coupled with political power and corruption and emerging democracy and decentralized management. By adopting multiple perspectives and using multiple lenses across nested scales of analyses, we seek to understand the dynamics of how the landscape influences anthropogenic resource use patterns and how resource use alters the landscape and the resulting synergies and feedbacks. Although Borneo is used as the specific context to explore these issues, comparisons and contrasts are also emphasized with other tropical regions (e.g., tropical Latin America and Africa), and the conceptual issues should be applicable worldwide in a variety of situations.


Technology, Society, and the Environment
(F&ES 83026/F&ES818/MGT561)
Arnulf Grubler


This seminar addresses technology's dual role as both source and remedy of global environmental change. The seminar first discusses conceptual and theoretical aspects of technological change from an interdisciplinary perspective including social science, history, economics, engineering, as well as management theory. Examples of technological change and its environmental impacts in agriculture, industries, and the service economy are addressed through case studies. Questions discussed include: Why are some technological innovations successful (e.g., cell phones) while others (e.g., fast breeder reactors) are not? What determines rates of change in the adoption of new technologies and how can these be accelerated? How many people can the earth feed? Is dematerialization actually occurring, and why? What are the implications of the Internet's digital North-South divide and what are strategies to overcome it? Active student participation is an essential ingredient of the seminar; students participate in seminar debates, perform case studies in home assignments, and also write a (short) final term paper on a mutually agreed-upon topic.

This seminar introduces research methods involving the built environment. It includes readings from urban and suburban history, geography, anthropology, and architecture as well as readings on narrative and graphic strategies for representing spaces and places. Participants present papers; chapters from longer projects are welcome.

 

Disaster, Degradation, Dystopia: Social Science Approaches to Environmental Perturbation and Change
(ANTH 572 01 (20397) /F&ES80176/F&ES869)
Michael Dove

This is an advanced seminar on the long tradition of social science scholarship on environmental perturbation and natural disasters, the relevance of which has been heightened by the current global attention to climate change. Topics covered include the academic literature on the social dimension of natural disasters, illustrated with a case study of volcanic hazard; the discursive dimensions of environmental degradation, focusing on deforestation and other case studies; climate change, including discursive dimensions at the global level and close-grained studies of adaptation at the local level; the current debate about the relationship between resource wealth and political conflict, focusing on the "green war" thesis, and the case of tropical forest commodities; and alternative perspectives on sustainable environmental relations, based on interdisciplinary work and work in the humanities.

Society and Environment: Introduction to Theory and Method
(ANTH 581 01 (20398))

This is an introductory graduate core course on the scope of social scientific contributions to environmental and natural resource issues. It is designed to be the first course for students who will be specializing in social science approaches as well as the last/only course for students who take only one course in this area. The approach taken in the course is inductive, problem-oriented, and case-study-based. Section I presents an overview of the field and course. Section II deals with the way that environmental problems are initially framed. Case studies focus on placing problems in their wider political context, new approaches to uncertainty and failure, and the importance of how the analytical boundaries to resource systems are drawn. Section III focuses on questions of method, including the dynamics of working within development projects, and the art of rapid appraisal and short-term consultancies. Section IV is concerned with local peoples and the environment, with case studies addressing the myth of slash-and-burn cultivation, livestock and the development discourse, and indigenous knowledge and its transformation. Section V presents lessons learned.

World Religions and Ecology: Asian Religions
(RLST 872 01 (20859) /F&ES80071/REL817/RLST280)
Mary Tucker
John Grim

This course examines the various ways in which religious ideas and practices have contributed to cultural attitudes and human interactions with nature. Examples are selected from Hinduism, Buddhism, Confucianism, and Daoism. The course examines such topics as symbols, images, and metaphors of nature in canonical texts, views of the divine as transcendent to the world, the indwelling of the sacred in the earth, the ethics of using and valuing nature, ritual practices that link humans to the natural world, and cosmology as orienting humans to the world and embedding them in place.

Indigenous Traditions and Ecology
(RLST 875 01 (11157) /F&ES80044/EVST270/RLST263/REL810)
John Grim

The course explores how particular indigenous peoples relate to local bioregions and biodiversity. Opening with an examination of such terms as "indigenous," "religion," and "ecology," the course proceeds to investigate religious studies and ethnography related to small-scale societies and the many ways in which they relate to local bioregions and biodiversity. The course examines indigenous ethnic diversity and cultural relationships to place, and the ways values associated with physical places are articulated in symbols, myths, rituals, and other embodied practices. Finally, this course involves questions of environmental justice, namely, the imposition of environmentally damaging projects on a people whose voice in decision making is diminished or totally eliminated.

Anthropology of the Global Economy for Development and Conservation
(ANTH 561 01 (10260) /F&ES80061)
Carol Carpenter

This seminar explores topics in the anthropology of the global economy that are relevant to development and conservation policy and practice. Anthropologists are often assumed to focus on micro- or local-level research, and thus to have limited usefulness in the contemporary, global world of development and conservation policy. In fact, however, they have been examining global topics since at least the 1980s, and very little current anthropological research is limited to the village level. More importantly, the anthropological perspective on the global economy is unique and important.

Social Science of Development and Conservation
(ANTH 597 01 (10261) /F&ES839/F&ES83056)
Carol Carpenter

This course provides a fundamental understanding of the social aspects involved in implementing sustainable development and conservation projects. Social science has two things to contribute to the practice of development and conservation. First, it provides ways of thinking about, researching, and working with social groupings-including rural households and communities, but also development and conservation institutions, states, and NGOs. Second, social science tackles the analysis of the knowledge systems that implicitly shape development and conservation policy and impinge on practice. The goal of the course is to stimulate students to apply informed and critical thinking to whatever roles they play in sustainable development and conservation, in order to move toward more environmentally and socially sustainable projects and policies.

Households, Communities, Gender (for Development and Conservation)
(ANTH 582 01 (20399) /F&ES83073)
Carol Carpenter

The implementation of development and conservation projects involving people requires an understanding of households, communities, and gender; unfortunately, policy is laden with mistaken assumptions about these social units. This course examines both the anthropology of households, communities, and gender, and common assumptions about them in development and conservation. Economic and political aspects of relations within these units are intimately linked, and are examined together. The course explores important global variations in the structure of households, communities, and gender. The structure of households, communities, and gender in any particular locality influences the economic and political relation with its region, nation, and the world system-with essential implications for development and conservation. The course aims to study local social units in order to understand their importance for regional, national, and global development and conservation. The goal is to encourage future policy makers and implementers to examine their assumptions about society, and to think more critically about the implications of these social units (and their variations around the world) for development and conservation.

Archetypes and the Environment
(F&ES 40004 01 (13528) /F&ES602)
Paul Draghi

This course explores the mythologies, literatures, arts, and folklore of a variety of cultures in search of archetypal characters whose role is to mediate between nature and society. Beginning with sources as early as The Epic of Gilgamesh and ending with contemporary film and media, the course seeks to examine and understand the ways in which diverse peoples integrate an awareness of their traditional and popular arts and cultures. The course makes use of works from a variety of languages, including Akkadian, Greek, Tibetan, Bhutanese, Chinese, German, French, and Italian, but all readings are available in English; students with reading abilities in foreign languages will be encouraged to examine primary sources wherever possible. The course includes visits to the Beinecke Rare Book and Manuscript Library, the Yale Center for British Art, and the Yale Art Gallery.
