Plants play a central role in human existence. Medicinal plants, in particular, have allowed for the continued survival of the human species. This book, based on over a decade of research in Southern Mexico with the Highland Maya, explores the relationship between medicinal plants, traditional ecological knowledge and the environment. The biodiversity of the region remains among the highest in the world, comprising more than 9000 plant species. Over 1600 employed for medicinal uses and knowledge for approximately 600 species is widespread. Medicinal plants play an overwhelmingly primary role in the daily health care of the Highland Maya. Three principal objectives are addressed: 1) identifying which medicinal plants are used; 2) determining the role of environmental variation on use and selection of medicinal plants; and 3) identifying which habitats are preferred for medicinal plant procurement. Findings demonstrate the overwhelming importance of human modified environments for medicinal plants. Explanations are presented from human ecology and biochemical ecology. Implications for conservation, health and the environment are discussed.
The most comprehensive collection of papers in the field to date, this volume presents state-of-the-art research and commentary from more than fifty of the world's leading ethnobiologists. Covering a wide range of ecosystems and world regions, the papers center on global change and the relationships among traditional knowledge, biological diversity, and cultural diversity. Specific themes include the acquisition, persistence, and loss of traditional ecological knowledge; intellectual property rights and benefits sharing; ethnobiological classification; medical ethnobotany; ethnoentomology; ethnobiology and natural resource management; homegardens; and agriculture and traditional knowledge. The volume will be of interest to scholars in anthropology, ecology, and related fields and also to professionals in conservation and indigenous rights organizations.
Environmental and Ecological Chemistry is a component of Encyclopedia of Chemical Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Environmental and Ecological Chemistry prsents the essential aspects such as: Fundamental Environmental Chemistry; Atmospheric Chemistry; Soil Chemistry; Aquatic Chemistry; Ecological Chemistry; Chemistry of Organic Pollutants Including Agrochemicals. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
Environmental Regulations and Standard Setting is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Environmental regulation and the setting of environmental standards is concerned with command-and-control standards and regulations to control most of the pollutants generated by anthropogenic activities impacting on the three main environmental compartments: air, water, and land (including waste). Methods of regulatory control are described along with all major associated issues, including criteria for standard sett...
Environmental Education and Awareness is a component of Encyclopedia of Human Resources Policy, Development and Management which is part of the global Encyclopedia of Life Support Systems (EOLSS), an integrated compendium of twenty one Encyclopedias. The Theme is organized into seven different topics which represent the main scientific areas of the theme: The first topic, Formal Environmental Education at Preschool, Primary and Secondary Levels; important issues of children's formal environmental education are discussed in this topic, considering that as future adults today's children are more likely than not to make adverse impacts on the natural environment and earth's life-support systems...
Pollution Control Technologies is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The volume on Pollution Control Technologies focuses largely concerned with strategies for pollution reduction, and pollution prevention if at all possible, using scientific and technological methods. Focusing primarily but not exclusively on air pollution, the Theme is written in simple English, avoiding both mathematical and chemical equations as far as possible to facilitate effective and widest possible dissemination. The conten...
Fresh Surface Water theme is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The occurrence of surface water in abundance is unique to planet Earth among the inner or terrestrial planets. This is only one of the environmental consequences of the anomalous properties of water. Water has been central to human life and human thought throughout history. The availability of fresh surface water varies between continents, between regions within any given continent, between countries in a given region, and between catchments in a given country...
Physiology and Maintenance is a component of Encyclopedia of Biological, Physiological and Health Sciences in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Physiology and Maintenance with contributions from distinguished experts in the field, discusses the functions of our body and their regulations which are some of the most fascinating areas of science. The content of the theme is organized with state-of-the-art presentations covering the following aspects of the subject: General Physiology; Enzymes: The Biological Catalysts of Life; Nutrition and Digestion; Renal Excretion; Endocrinology; Respiration; Blood Circulation: Its Dynamics And Physiological Control; Locomotion in Sedentary Societies; Neurophysiology; Plant Physiology and Environment : A Synopsis, which are then expanded into multiple subtopics, each as a chapter. These five volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
