This book was released on 2012-12-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main activities of the economically active population around The Iztaccíhuatl and Popocatépetl volcanoes region lie in the primary sector (65- 90%). Of the people working in this sector, those dependent on agricultural or pastoral activities generally have an income significantly lower than the minimum wage in Mexico. Of the activities in the area, these agricultural, pastoral, and forestry activities probably have the most direct effect on the ecology of the volcanoes and its immediate surroundings. Traditional farmers, producing crops such as beans, pumpkins and cucumbers, generally work on small fields using traditional methods and animal traction. Modern farming, geared towards intensive production develops on larger sites making use of modern machinery, fertilizers, and pesticides. As the area under agriculture continues to increase every year, the attendant opening of large forested areas, soil modification, and ensuing erosion make it almost impossible for forest recovery. Extensive forestry in the region mainly concerns cutting and collecting wood, cutting Pinus-branches for torches or for utensils for open-fire cooking, collection of mushrooms, and hunting. Although these (often clandestine) activities seem to be small-scale, their adverse effects on the forest have been substantial. Weekend visitors from Mexico City heavily dominate recreation, with tourism concentrated near the roads leading to and inside the park. Lacking organization and facilities, most recreational activities have had significant environmental impact on the area In many countries, the decline of nature has occurred because of changes in land use.

Download or read book Volcanic Activity and Human Ecology written by Payson D. Sheets and published by Elsevier. This book was released on 2013-09-24 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic Activity and Human Ecology deals with dating, chronology, stratigraphy, volcanic activity, and with the impacts of volcanism on animals, plants, human populations, and the environment. Some of the chapters explain how such findings must be weighed against other causes that influence human behavior and survival, such as factors of social customs, climatic change, shifting biogeographic patterns, disease, and the ability to adapt. Each of the chapters that assess the possible human response to volcanism does so by searching for multiple explanations of the archaeological record, avoiding the simple argument that people were dramatically and inevitably overcome by catastrophic geologic events. The book begins with discussions of volcanism as seen by geologists and pedologists. These include s a general overview of volcanoes and volcanism; a review of the production, dispersal, and properties of tephra and of the geologic methods used to study tephra; and the nature of volcanic soils and their economic impact. Subsequent chapters use the geologic and modern records to examine volcanoes as hazards to people. The final series of papers deals with the interrelationships between volcanism and human occupations as seen through the archaeological, paleobotanical, and paleozoological records.

Download or read book Assembly Rules and Restoration Ecology written by Vicky M. Temperton and published by . This book was released on 2004-05 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how ecosystems are assembled -- how the species that make up a particular biological community arrive in an area, survive, and interact with other species -- is key to successfully restoring degraded ecosystems. Yet little attention has been paid to the idea of assembly rules in ecological restoration, in both the scientific literature and in on-the-ground restoration efforts. Assembly Rules and Restoration Ecology, edited by Vicky M. Temperton, Richard J. Hobbs, Tim Nuttle, and Stefan Halle, addresses that shortcoming, offering an introduction, overview, and synthesis of the potential role of assembly rules theory in restoration ecology. It brings together information and ideas relating to ecosystem assembly in a restoration context, and includes material from a wide geographic range and a variety of perspectives. Assembly Rules and Restoration Ecology contributes new knowledge and ideas to the subjects of assembly rules and restoration ecology and represents an important summary of the current status of an emerging field. It combines theoretical and practical aspects of restoration, making it a vital compendium of information and ideas for restoration ecologists, professionals, and practitioners.

Download or read book Human Settlements and Planning for Ecological Sustainability written by Keith Pezzoli and published by MIT Press. This book was released on 2000 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many areas of the world, environmental degradation in and around human settlements is undermining prospects for both socioeconomic justice and ecological sustainability. To explore the issues involved in this worldwide problem, Keith Pezzoli focuses on a dramatic instance of conflict that grew out of the unauthorized penetration of human settlements into the Ajusco greenbelt zone, a vital part of Mexico City's ecological reserve. The heart of the book is the story of what happened when residents of the Ajusco settlements fought relocation by proposing that the areas be transformed into productive ecology settlements. Pezzoli draws upon urban and regional planning theory and practice to examine biophysical as well as ethical and social sides of the story, and he uses the Mexican experience to identify planning strategies to link economy, ecology, and community in sustainable development. -- Publisher description.

Download or read book Active Volcanoes of Chiapas Mexico El Chich n and Tacan written by Teresa Scolamacchia and published by Springer. This book was released on 2015-02-25 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication summarizes the studies carried out at two of the most active volcanoes of Chiapas (Mexico): El Chichón and Tacaná. El Chichón erupted explosively in 1982 killing more than 2000 people being the worst volcanic disaster in Mexico, and Tacaná produced two mild phreatic explosions in 1950 and 1986. Only after these explosions a surge of new studies began to unreveal their volcanic history and impact. This book presents the state of the art advances in topics related to the geologic setting of the two volcanoes, their eruptive history and composition of erupted products, the hydrothermal systems and their manifestations. Volcanic hazards and risks and possible mitigation plans are discussed based on the experience of the catastrophic eruption of El Chichón that occurred in 1982. The book will also include previously unpublished material on the flora and the fauna of the region and archaeological and social aspects of the area that is inhabited by indigenous people.

Download or read book Humans and the Environment written by Matthew I. J. Davies and published by OUP Oxford. This book was released on 2013-06-27 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environment has always been a central concept for archaeologists and, although it has been conceived in many ways, its role in archaeological explanation has fluctuated from a mere backdrop to human action, to a primary factor in the understanding of society and social change. Archaeology also has a unique position as its base of interest places it temporally between geological and ethnographic timescales, spatially between global and local dimensions, and epistemologically between empirical studies of environmental change and more heuristic studies of cultural practice. Drawing on data from across the globe at a variety of temporal and spatial scales, this volume resituates the way in which archaeologists use and apply the concept of the environment. Each chapter critically explores the potential for archaeological data and practice to contribute to modern environmental issues, including problems of climate change and environmental degradation. Overall the volume covers four basic themes: archaeological approaches to the way in which both scientists and locals conceive of the relationship between humans and their environment, applied environmental archaeology, the archaeology of disaster, and new interdisciplinary directions.The volume will be of interest to students and established archaeologists, as well as practitioners from a range of applied disciplines.

Download or read book Earth at Risk in the 21st Century Rethinking Peace Environment Gender and Human Water Health Food Energy Security and Migration written by Úrsula Oswald Spring and published by Springer Nature. This book was released on 2020-04-03 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth at Risk in the 21st Century offers critical interdisciplinary reflections on peace, security, gender relations, migration and the environment, all of which are threatened by climate change, with women and children affected most. Deep-rooted gender discrimination is also a result of the destructive exploitation of natural resources and the pollution of soils, water, biota and air. In the Anthropocene, the management of human society and global resources has become unsustainable and has created multiple conflicts by increasing survival threats primarily for poor people in the Global South. Alternative approaches to peace and security, focusing from bottom-up on an engendered peace with sustainability, may help society and the environment to be managed in the highly fragile natural conditions of a ‘hothouse Earth’. Thus, the book explores systemic alternatives based on indigenous wisdom, gift economy and the economy of solidarity, in which an alternative cosmovision fosters mutual care between humankind and nature. • Special analysis of risks to the survival of humankind in the 21st century. • Interdisciplinary studies on peace, security, gender and environment related to global environmental and climate change. • Critical reflections on gender relations, peace, security, migration and the environment • Systematic analysis of food, water, health, energy security and its nexus. • Alternative proposals from the Global South with indigenous wisdom for saving Mother Earth.
