Book Description
We live in a world of wide pendulum swings regarding management policies for protected areas, particularly as they affect the involvement of local people in management. Such swings can be polarizing and halt on-the-ground progress. There is a need to find ways to protect biodiversity while creating common ground and building management capacity thr

Book Description
This highly topical study of tropical deforestation in Mexico reports on the first phase of the Land-Cover and Land-Use Change in the Southern Yucatan Peninsular Region Project (LCLUC-SYPR): a large, multi-institutional, and team-based study designed to understand and project land changes in a development frontier that pits the rapidly growing needs of smallholder farmers to cut down forests for cultivation against federally sponsored initiatives committed to various international programmes of forest preservation and complementary economic programmes. The SYPR project is a response to inderdisciplinary defined research themes deemed critical to global environmental change and complementary international research agendas (e.g. environment and development, ecosystem assessment, biotic diversity). Pivotal among these agendas are those posed by the Land-Use/Cover Change (LUCC) effort of the International Geosphere-Biosphere Programme and the International Human Dimensions of Global Environmental Change Programme as it is linked through such US sponsors as the National Aeronautics and Space Administration (NASA) and the National Science Foundation (NSF). The themes (i.e. questions and subjects) posed by these programmes and organization are 'integrated' or 'synthesis' in kind, meaning that they rest within the intersection of formal disciplines and are intended to fit into a larger, systems framework about human-environment relationships and the structure and function of the biosphere. The editors of this volume, as most of its contributors, come from the disciplines of geography, ecology, and economics. The lead editor, the geographer B. L. Turner II, has spent most of his career in pursuit of understanding different aspects of tropical deforestation and agriculture.

Book Description
Enduring differences between protected areas and local people have produced few happy compromises, but at the Calakmul Biosphere Reserve in the southern Mexican state of Campeche, government agents and thousands of local people collaborated on an expansive program to alleviate these tensions—a conservation-development agenda that aimed to improve local people’s standard of living while preserving natural resources. Calakmul is home to numerous endangered species and raises a common question: How can environmental managers and citizens reconcile competing ecological desires? For a brief time in the 1990s, collaborations at Calakmul were heralded as a vital example of melding local management, forest conservation, and economic development. In Fields of Power, Forests of Discontent, Nora Haenn questions the rise and fall of this conservation program to examine conservation at the intersection of national-international agendas and local political-economic interests. While other assessments of such programs have typically focused on why they do or do not succeed, Haenn instead considers conservation’s encounter with people’s everyday lives—and how those experiences affect environmental management. Haenn explores conservation and development from two perspectives: first regionally, to look at how people used conservation to create a new governing entity on a tropical frontier once weakly under national rule; then locally, focusing on personal histories and aspects of community life that shape people's daily lives, farming practices, and immersion in development programs—even though those programs ultimately fail to resolve economic frustrations. She identifies how key political actors, social movements, and identity politics contributed to the instability of the Calakmul alliance. Drawing on extensive interviews with Reserve staff, including its director, she connects regional trends to village life through accounts of disputes at ejido meetings and the failure of ejido development projects. In the face of continued difficulty in creating a popular conservation in Calakmul, Haenn uses lessons from people's lives—history, livelihood, village organization, expectations—to argue for a "sustaining conservation," one that integrates social justice and local political norms with a new, more robust definition of conservation. In this way, Fields of Power, Forests of Discontent goes beyond local ethnography to encourage creative discussion of conservation's impact on both land and people.

Book Description
The Maya Tropical Forest, which occupies the lowlands of southern Mexico, Guatemala, and Belize, is the closest rainforest to the United States and one of the most popular tourist destinations in the Western Hemisphere. It has been home to the Maya peoples for nearly four millennia, starting around 1800 BC. Ancient cities in the rainforest such as Palenque, Yaxchilan, Tikal, and Caracol draw thousands of tourists and scholars seeking to learn more about the prehistoric Maya. Their contemporary descendants, the modern Maya, utilize the forest's natural resources in village life and international trade, while striving to protect their homeland from deforestation and environmental degradation. Writing for both visitors and conservationists, James Nations tells the fascinating story of how ancient and modern Maya peoples have used and guarded the rich natural resources of the Maya Tropical Forest. He opens with a natural history that profiles the forest's significant animals and plants. Nations then describes the Maya peoples, biological preserves, and major archaeological sites in Mexico, Guatemala, and Belize. Drawing on more than twenty-five years of conservation work in the Maya Tropical Forest, Nations tells first-hand stories of the creation of national parks and other protected areas to safeguard the region's natural resources and archaeological heritage. He concludes with an expert assessment of the forest's future in which he calls for expanded archaeological tourism to create an ecologically sustainable economic base for the region.

Book Description
A major, worldwide threat to agricultural productivity is undoubtedly due to environments with stressful factors, including drought, salinity, and extreme temperatures. Based on contributions presented at the International Conference on Biosaline Agriculture and High Salinity Tolerance, held in Gammarth, Tunisia, November 2006, this book reviews the current state of knowledge in biosaline agriculture and high salinity tolerance in plants.

Book Description
The knowledge of plant responses to various abiotic stresses is crucial to understand their underlying mechanisms as well as the methods to develop new varieties of crops, which are better suited to the environment they are grown in. Environmental Stress Physiology of Plants and Crop Productivity provides readers a timely update on the knowledge about plant responses to a variety of stresses such as salinity, temperature, drought, oxidative stress and mineral deficiencies. Chapters focus on biochemical mechanisms identified in plants crucial to adapting to specific abiotic stressors along with the methods of improving plant tolerance. The book also sheds light on plant secondary metabolites such as phenylpropanoids and plant growth regulators in ameliorating the stressful conditions in plants. Additional chapters present an overview of applications of genomics, proteomics and metabolomics (including CRISPR/CAS techniques) to develop abiotic stress tolerant crops. The editors have also provided detailed references for extended reading to support the information in the book. Environmental Stress Physiology of Plants and Crop Productivity is an informative reference for scholars and researchers working in the field of botany, agriculture, crop science and physiology, soil science, and environmental sciences.
