Download or read book Urban Air Pollution and Forests written by Mark E. Fenn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, roughly half of the world's population lives in urban centers. There are now more than 20 cities with a population of over 10 million inhabitants, compared to less than 5 about 50 years ago. This tendency toward urbanization is expected to continue, particularly in the developing world. A consequence of this growing trend is that millions of people are being exposed to harmful levels of urban air pollutants caused mainly by emissions from motor vehicles and from industrial and domestic activities involving the combustion of fossil fuels. The driving force for the design and implementation of emission control strate gies aimed at improving air quality has been the protection of the health of the population in urban centers. There are, however, other consequences of the pres ence of air pollutants besides the direct effect on human health. Reduced visibil ity, damage to monuments and buildings, and many other such consequences indirectly affect our quality of life. Another set of consequences involves damage to ecological systems. In fact, the nature of "photochemical smog" was first uncovered in the 1950s in connection with observations of its harmful effects on crops and plants in the vicinity of Los Angeles.
Download or read book Carbon and Nitrogen in Forest Ecosystems Series I written by Yowhan Son and published by MDPI. This book was released on 2021-01-20 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the differences in carbon and nitrogen distribution and cycling both spatially and temporally using various approaches is essential in forest ecosystems. In addition, the influence of biotic and abiotic factors as well as natural and artificial disturbances on carbon and nitrogen cycling need to first be understood before drawing their implications to forest management practices. This Special Issue aims to understand carbon and nitrogen distribution and cycling in forest ecosystems for ecosystem-based forest management under different natural and artificial disturbances.
Download or read book Mexico s Community Forest Enterprises written by David Barton Bray and published by University of Arizona Press. This book was released on 2020-11-24 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The road to sustainable forest management and stewardship has been debated for decades. Some advocate for governmental control and oversight. Some say that the only way to stem the tide of deforestation is to place as many tracts as possible under strict protection. Caught in the middle of this debate, forest inhabitants of the developing world struggle to balance the extraction of precarious livelihoods from forests while responding to increasing pressures from national governments, international institutions, and their own perceptions of environmental decline to protect biodiversity, restore forests, and mitigate climate change. Mexico presents a unique case in which much of the nation’s forests were placed as commons in the hands of communities, who, with state support and their own entrepreneurial vigor, created community forest enterprises (CFEs). David Barton Bray, who has spent more than thirty years engaged with and researching Mexican community forestry, shows that this reform has transformed forest management in that country at a scale and level of maturity unmatched anywhere else in the world. For decades Mexico has been conducting a de facto large-scale experiment in the design of a national social-ecological system (SES) focused on community forests. What happens when you give subsistence communities rights over forests, as well as training, organizational support, equipment, and financial capital? Do the communities destroy the forest in the name of economic development, or do they manage them sustainably, generating current income while maintaining intergenerational value as a resource for their children? Bray shares the scientific and social evidence that can now begin to answer these questions. This is an invaluable resource for students, researchers, and the interested public on the future of global forest resilience and the possibilities for a good Anthropocene.

Download or read book Moral Ecology of a Forest written by José E. Martínez-Reyes and published by University of Arizona Press. This book was released on 2016-11-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests are alive, filled with rich, biologically complex life forms and the interrelationships of multiple species and materials. Vulnerable to a host of changing conditions in this global era, forests are in peril as never before. New markets in carbon and environmental services attract speculators. In the name of conservation, such speculators attempt to undermine local land control in these desirable areas. Moral Ecology of a Forest provides an ethnographic account of conservation politics, particularly the conflict between Western conservation and Mayan ontological ecology. The difficult interactions of the Maya of central Quintana Roo, Mexico, for example, or the Mayan communities of the Sain Ka’an Biosphere, demonstrate the clashing interests with Western biodiversity conservation initiatives. The conflicts within the forest of Quintana Roo represent the outcome of nature in this global era, where the forces of land grabbing, conservation promotion and organizations, and capitalism vie for control of forests and land. Forests pose living questions. In addition to the ever-thrilling biology of interdependent species, forests raise questions in the sphere of political economy, and thus raise cultural and moral questions. The economic aspects focus on the power dynamics and ideological perspectives over who controls, uses, exploits, or preserves those life forms and landscapes. The cultural and moral issues focus on the symbolic meanings, forms of knowledge, and obligations that people of different backgrounds, ethnicities, and classes have constructed in relation to their lands. The Maya Forest of Quintana Roo is a historically disputed place in which these three questions come together.
Download or read book The Community Forests of Mexico written by David Barton Bray and published by University of Texas Press. This book was released on 2009-03-16 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico leads the world in community management of forests for the commercial production of timber. Yet this success story is not widely known, even in Mexico, despite the fact that communities around the globe are increasingly involved in managing their own forest resources. To assess the achievements and shortcomings of Mexico's community forest management programs and to offer approaches that can be applied in other parts of the world, this book collects fourteen articles that explore community forest management from historical, policy, economic, ecological, sociological, and political perspectives. The contributors to this book are established researchers in the field, as well as many of the important actors in Mexico's nongovernmental organization sector. Some articles are case studies of community forest management programs in the states of Michoacán, Oaxaca, Durango, Quintana Roo, and Guerrero. Others provide broader historical and contemporary overviews of various aspects of community forest management. As a whole, this volume clearly establishes that the community forest sector in Mexico is large, diverse, and has achieved unusual maturity in doing what communities in the rest of the world are only beginning to explore: how to balance community income with forest conservation. In this process, Mexican communities are also managing for sustainable landscapes and livelihoods.

Download or read book Instituting Nature written by Andrew S. Mathews and published by MIT Press. This book was released on 2011-11-04 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of how encounters between forestry bureaucrats and indigenous forest managers in Mexico produced official knowledge about forests and the state. Greater knowledge and transparency are often promoted as the keys to solving a wide array of governance problems. In Instituting Nature, Andrew Mathews describes Mexico's efforts over the past hundred years to manage its forests through forestry science and biodiversity conservation. He shows that transparent knowledge was produced not by official declarations or scientists' expertise but by encounters between the relatively weak forestry bureaucracy and the indigenous people who manage and own the pine forests of Mexico. Mathews charts the performances, collusions, complicities, and evasions that characterize the forestry bureaucracy. He shows that the authority of forestry officials is undermined by the tension between local realities and national policy; officials must juggle sweeping knowledge claims and mundane concealments, ambitious regulations and routine rule breaking. Moving from government offices in Mexico City to forests in the state of Oaxaca, Mathews describes how the science of forestry and bureaucratic practices came to Oaxaca in the 1930s and how local environmental and political contexts set the stage for local resistance. He tells how the indigenous Zapotec people learned the theory and practice of industrial forestry as employees and then put these skills to use when they become the owners and managers of the area's pine forests—eventually incorporating forestry into their successful claims for autonomy from the state. Despite the apparently small scale and local contexts of this balancing act between the power of forestry regulations and the resistance of indigenous communities, Mathews shows that it has large implications—for how we understand the modern state, scientific knowledge, and power and for the global carbon markets for which Mexican forests might become valuable.

Download or read book Forest Plans of North America written by Jacek P. Siry and published by Academic Press. This book was released on 2015-03-13 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Plans of North America presents case studies of contemporary forest management plans developed for forests owned by federal, state, county, and municipal governments, communities, families, individuals, industry, investment organizations, conservation organizations, and others in the United States, Canada, and Mexico. The book provides excellent real-life examples of contemporary forest planning processes, the various methods used, and the diversity of objectives and constraints faced by forest owners. Chapters are written by those who have developed the plans, with each contribution following a unified format and allowing a common, clear presentation of the material, along with consistent treatment of various aspects of the plans. This work complements other books published by members of the same editorial team (Forest Management and Planning, Introduction to Forestry and Natural Resource Management), which describe the planning process and the various methods one might use to develop a plan, but in general do not, as this work does, illustrate what has specifically been developed by landowners and land managers. This is an in-depth compilation of case studies on the development of forest management plans by the different landowner groups in North America. The book offers students, practitioners, policy makers, and the general public an opportunity to greatly improve their appreciation of forest management and, more importantly, foster an understanding of why our forests today are what they are and what forces and tools may shape their tomorrow. Forest Plans of North America provides a solid supplement to those texts that are used as learning tools for forest management courses. In addition, the work functions as a reference for the types of processes used and issues addressed in the early 21st century for managing land resources. Presents 40-50 case studies of forest plans developed for a wide variety of organizations, groups, and landowners in North America Illustrates plans that have specifically been developed by landowners and land managers Features engaging, clearly written content that is accessible rather than highly technical, while demonstrating the issues and methods involved in the development of the plans Each chapter contains color photographs, maps, and figures

This book was released on 2013-05-27 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species
Download or read book Ecology and Man in Mexico s Central Volcanoes Area written by G.W. Heil and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 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.
