The economics of climate change
2011
While debates over the consequences of climate change are often pessimistic, historical data from the past two centuries indicate many viable opportunities for responding to potential changes. This volume takes a close look at the ways in which economies—particularly that of the United States—have adjusted to the challenges climate change poses, including institutional features that help insulate the economy from shocks, new crop varieties, irrigation, flood control, and ways of extending cultivation to new geographic areas. These innovations indicate that people and economies have considerable capacity to acclimate, especially when private gains complement public benefits. Options for adjusting to climate change abound, and with improved communication and the emergence of new information and technologies, the potential for adaptation will be even greater in the future.

2006
This collection of studies by anthropologists, botanists, ecologists, and biologists is an important contribution to the emerging field of historical ecology. The book combines cutting-edge research with new perspectives to emphasize the close relationship between humans and their natural environment. Contributors examine how alterations in the natural world mirror human cultures, societies, and languages. Treating the landscape like a text, these researchers decipher patterns and meaning in the Ecuadorian Andes, Amazonia, the desert coast of Peru, and other regions in the neotropics. They show how local peoples have changed the landscape over time to fit their needs by managing and modifying species diversity, enhancing landscape heterogeneity, and controlling ecological disturbance. In turn, the environment itself becomes a form of architecture rich with historical and archaeological significance. Time and Complexity in Historical Ecology explores thousands of years of ecological history while also addressing important contemporary issues, such as biodiversity and genetic variation and change. Engagingly written and expertly researched, this book introduces and exemplifies a unique method for better understanding the link between humans and the biosphere.

In 2050, the billions of people living on Earth have found a way to manage the planetary system effectively. Everyone has access to adequate food, shelter, and clean water. Human health is no longer considered outside of the health of the ecosystems in which people live. Ecological awareness is an integral part of education. People respond effectively to social and environmental hazards, and societies care for the most vulnerable amongst them. The economy, too, has shifted. Carbon dioxide management is under control, and energy efficiency is the norm. The remaining rainforests have been preserved. Coral reefs are recovering. Fish stocks are thriving. Is any of this really possible? How can our complex social and economic systems interact with a complex planetary system undergoing rapid change to create a future we all want?
This book is a contextualised collation of ideas articulated by the 50 participants of the Planet 2050 workshop held in Lund in October 2008, as part of The Planet in 2050, an interdisciplinary Fast Track Initiative of the International Geosphere-Biosphere Programme. Participants were selected from academia and the sustainability practice community to give a wide-ranging, multi-cultural, trans-disciplinary set of perspectives.
This collection explores four broad sectoral themes: energy and technologies; development, economies and culture; environment; and land use change. By doing so, this book emphasises the importance of a social dialogue on our collective future, and our responsibility to the Earth. It makes strong statements about what needs to happen to the global economy for a sustainable future and documents a new kind of scholarly discussion, engaging people from diverse knowledge communities in a spirit of exploration and reflexivity. The book provides a focus for dialogue and further study for postgraduates and researchers interested in global change as a multi-faceted, socio-environmental
Include the true value of nature when rebuilding economies after coronavirus

BackgroundNatural and anthropogenic wildfires burn large areas of arid and semi-arid forests with significant socio-economic and environmental impacts. Fire regimes are controlled by climate, vegetation type, and anthropogenic factors such as ignition sources and human-induced disturbances. Projections of climate and land-use change suggest that these controlling factors will change, altering fire regimes in the near future. In the southern Central Monte, Mendoza, Argentina, the factors that modulate the fire temporal and spatial variability are poorly understood. We reconstructed the fire history of southeast of Mendoza from 1984 to 2023 and investigated the relationships between fire extent and climate variability at seasonal and interannual scales. Burned areas were determined using Google Earth Engine by processing Landsat 5-TM, Landsat 7-ETM+ , and Landsat 8-OLI-TIRS sensor imagery.ResultsThe region exhibited high spatial and temporal variability in fire occurrence, being a mosaic of areas with different fire histories and recovery times. Between 1985 and 2023, fire recurrence ranged from sites unburned to sites with up to 14 fires. The occurrence of large fires was strongly favored by a combination of a year with abundant spring–early summer precipitation, which favors fuel accumulation, followed by a year of low spring–early summer precipitation. Precipitation and burnt area showed a very pronounced 6–7 year cycle, suggesting a dominant climatic control on fire occurrence.ConclusionsFire distribution in southeastern Mendoza forests is not homogeneous, resulting in a mosaic of patches with different fire histories. This heterogeneity may be related to vegetation patterns and land use. The temporal variability of fires is strongly influenced by climate variability, which would promote fuel production and subsequent drying. Large fires are concentrated in periods of high interannual precipitation variability. Climate change scenarios predict an increase in temperature and precipitation variability in the region, suggesting future changes in fire dynamics. Our results contribute to the development of fire guidelines for southeastern Mendoza forests, focusing on periods of wet years followed by dry years that favor fire occurrence and spread.

BackgroundStone pine (Pinus pinea), a drought-resistant species, has significant socio-economic benefits and increasing interest for the establishment of productive plantations in several countries, especially in a climate change context. Monitoring hourly stem diameter variations contributes to the understanding of the tree-growth response to changes in environmental conditions and management. By monitoring the diameter expansion of tree stems, high-resolution band dendrometers were used to study the development of adult trees growing in a semi-arid coastal environment of central Chile under fertilized and non-fertilized soil conditions through the span of a year.ResultsShort cycles (< 21 h) were few in fertilized and non-fertilized trees (6 and 4, respectively), whereas long cycles (> 28 h) occurred at a higher frequency in fertilized trees (16 vs 6). Most of the circadian cycles were regular (24 ± 3 h). The longest cycle duration (59 h) was observed in fertilized trees during spring. In all seasons, each phase of the circadian cycle, especially during the stem diameter increment phase (P3, irreversible growth), started earlier in fertilized than in control trees. P3 duration was significantly longer in fertilized than in control trees in springtime. The maximum shrinkage (P1) was observed in summer for both treatments. Stem diameter increased faster in fertilized than in control trees throughout the year, with the highest accumulation occurring in spring and the lowest in autumn. The daily variability pattern showed lower growth under high temperature across seasons.ConclusionsThis study highlights the importance of fertilization in enhancing stone pine diameter growth. This cultural practice should be further explored to contribute to the mitigation of climate change effects in semi-arid environments.

Modern crises and traditional strategies
2007,2011
The 1990s have seen a growing interest in the role of local ecological knowledge in the context of sustainable development, and particularly in providing a set of responses to which populations may resort in times of political, economic and environmental instability. The period 1996-2003 in island southeast Asia represents a critical test case for understanding how this might work. The key issues explored in this book are the creation, erosion and transmission of ecological knowledge, and hybridization between traditional and scientifically-based knowledge, amongst populations facing environmental stress (e.g. 1997 El Niño), political conflict and economic hazards. The book will also evaluate positive examples of how traditional knowledge has enabled local populations to cope with these kinds of insecurity.
Environmentalism and Cultural Theory
1996
The last decade has seen a dramatic increase in the attention paid by social scientists to environmental issues, and a gradual acknowledgement, in the wider community, of the role of social science in the public debate on sustainability. At the same time, the concept of `culture', once the property of anthropologists has gained wide currency among social scientist. These trends have taken place against a growing perception, among specialist and public, of the global nature of contemporary issues. This book shows how an understanding of culture can throw light on the way environmental issues are perceived and interpreted, both by local communities and within the contemporary global arena.Taking an anthropological approach the book examines the relationship between human culture and human ecology, and considers how a cultural approach to the study of environmental issues differs from other established approaches in social science. This book adds significantly to our understanding of environmentalism as a contemporary phenomenon, by demonstrating the distinctive contribution of social and cultural anthropology to the environmental debate. It will be of particular interest to students and researchers in the fields of social science and the environment.
Population growth, resource consumption, and the environment
1995,2006,2000
A public-policy summary of the academic chapters presented at the 1993 Whistler Conference \"Population, Consumption and the Environment\" in which scholars from the world religions and the aboriginal traditions, as well as scientists, demographers, philosophers and economists from Canada, the U.S., Africa, Japan and India examined the double-sided problem of population pressure and excess consumption, and the resulting degradation of the environment.
