This book was released on 2018 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have played a significant role in the geomorphic evolution of the Belize River Valley in western Belize over the past 4,000 years, and this anthropogenic landscape still influences land use and flooding regimes today. Using LiDAR and GIS, fieldwork and lab analyses, I have studied the ways in which ancient Maya construction and agriculture affected the sediment budget thereby influencing geomorphic evolution of the river system. Soil geochemistry and radiocarbon dating have identified potential paleosols characterized by high levels of phosphorus, calcium, and potassium. These horizons are also composed of clay-sized particles, abundant organic matter and elevated magnetic susceptibility values. These buried soils are often overlain by a deposit of coarse, non-local sandy material that was transported from the Maya Mountains some 50 km away. These results may suggest that Maya activity caused changes to the Belize River’s sediment budget, thus contributing to the geomorphic evolution of the fluvial landscape. More research is required to further test this hypothesis

Download or read book Climate and Conservation written by Jodi A. Hilty and published by Island Press. This book was released on 2012-05-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate and Conservation presents case studies from around the world of leading-edge projects focused on climate change adaptation-regional-scale endeavors where scientists, managers, and practitioners are working to protect biodiversity by protecting landscapes and seascapes in response to threats posed by climate change. The book begins with an introductory section that frames the issues and takes a systematic look at planning for climate change adaptation. The nineteen chapters that follow examine particular case studies in every part of the world, including landscapes and seascapes from equatorial, temperate, montane, polar, and marine and freshwater regions. Projects profiled range from North American grasslands to boreal forests to coral reefs to Alpine freshwater environments. Chapter authors have extensive experience in their respective regions and are actively engaged in working on climate-related issues. The result is a collection of geographical case studies that allows for effective cross-comparison while at the same time recognizing the uniqueness of each situation and locale. Climate and Conservation offers readers tangible, place-based examples of projects designed to protect large landscapes as a means of conserving biodiversity in the face of the looming threat of global climate change. It informs readers of how a diverse set of conservation actors have been responding to climate change at a scale that matches the problem, and is an essential contribution for anyone involved with large-scale biodiversity conservation.

This book was released on 2018-11-05 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.

Download or read book Strategies and Tools for a Sustainable Rural Rio de Janeiro written by Udo Nehren and published by Springer. This book was released on 2018-08-16 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of recent developments in land, ecosystem, and water management in the Brazilian state of Rio de Janeiro. The state is located in the biodiversity hotspot of the Atlantic Forest (Mata Atlântica), a biome characterized by high biological diversity and endemism. At the same time the state of Rio de Janeiro emerged to one of the economic hubs in Latin America. This development process has been accompanied by population growth, industrialization, urbanization, as well as consumption and degradation of land and water resources. In the past years many efforts have been made to stop or at least slow down these degradation processes and restore degraded environments with the overall goal to bring together sustainable management of natural resources, nature conservation, and economic development. An overview is provided of the different strategies and tools that have been developed in the fields of agriculture, ecosystem management and biodiversity, integrated water management, land restoration, disaster risk reduction and climate change adaptation, as well as environmental governance and economic instruments. This book covers a wide spectrum from applied research to science‐policy interfaces, planning concepts, and technical tools and has a model character for other rural areas in Latin America. Target groups are scientists, practitioners, policy makers and graduate students in the field of environmental management. The different chapters are written by researchers and practitioners of the German‐Brazilian project INTECRAL (Integrated Eco Technologies and Services for a Sustainable Rural Rio de Janeiro), the rural development program Rio Rural under the state secretary for agriculture and animal husbandry, as well as invited scientists from Brazilian universities and research institutes. It bridges existing gaps between science, policies, and practice in rural development.
Download or read book The Value of Things written by Jennifer P. Mathews and published by University of Arizona Press. This book was released on 2017-04-11 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jade, stone tools, honey and wax, ceramics, rum, land. What gave these commodities value in the Maya world, and how were those values determined? What factors influenced the rise and fall of a commodity’s value? The Value of Things examines the social and ritual value of commodities in Mesoamerica, providing a new and dynamic temporal view of the roles of trade of commodities and elite goods from the prehistoric Maya to the present. Editors Jennifer P. Mathews and Thomas H. Guderjan begin the volume with a review of the theoretical literature related to the “value of things.” Throughout the volume, well-known scholars offer chapters that examine the value of specific commodities in a broad time frame—from prehistoric, colonial, and historic times to the present. Using cases from the Maya world on both the local level and the macro-regional, contributors look at jade, agricultural products (ancient and contemporary), stone tools, salt, cacao (chocolate), honey and wax, henequen, sugarcane and rum, land, ceramic (ancient and contemporary), and contemporary tourist handicrafts. Each chapter author looks into what made their specific commodity valuable to ancient, historic, and contemporary peoples in the Maya region. Often a commodity’s worth goes far beyond its financial value; indeed, in some cases, it may not even be viewed as something that can be sold. Other themes include the rise and fall in commodity values based on perceived need, rarity or overproduction, and change in available raw materials; the domestic labor side of commodities, including daily life of the laborers; and relationships between elites and nonelites in production. Examining, explaining, and theorizing how people ascribe value to what they trade, this scholarly volume provides a rich look at local and regional Maya case studies through centuries of time.

Download or read book The Leatherback Turtle written by James R. Spotila and published by JHU Press. This book was released on 2015-10-30 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive book ever written on leatherback sea turtles. Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.
Download or read book Latin America and the Caribbean LAC Report written by International Assessment of Agricultural Knowledge, Science, and Technology for Development (Project) and published by Iaastd. This book was released on 2009 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Assessment of Agricultural Knowledge, Science, and Technology for Development (IAASTD) looks realistically at how we could effectively use agriculture/AKST to help us meet development and sustainability goals. An unprecedented three-year collaborative effort, the IAASTD involved more than 400 authors in 110 countries and cost more than $11 million. It reports on the advances and setbacks of the past fifty years and offers options for the next fifty years. The results of the project are contained in seven reports: a Global Report, five regional Sub-Global Assessments, and a Synthesis Report. The Global Report gives the key findings of the Assessment, and the five Sub-Global Assessments address regional challenges. The volumes present options for action. All of the reports have been extensively peer-reviewed by governments and experts and all have been approved by a panel of participating governments. The Sub-Global Assessments all utilize a similar and consistent framework: examining and reporting on the impacts of AKST on hunger, poverty, nutrition, human health, and environmental/social sustainability. The five Sub-Global Assessments cover the following regions: Central and West Asia and North Africa (CWANA) East and South Asia and the Pacific (ESAP) Latin America and the Caribbean (LAC) North America and Europe (NAE) Sub-Saharan Africa (SSA)
Download or read book Lake Chilwa written by M. Kalk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.
Download or read book Sustaining the World s Wetlands written by Richard Smardon and published by Springer Science & Business Media. This book was released on 2009-06-13 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands throughout the world, including those described in this book are among the most sensitive and vulnerable ecosystems. They are critical habitats to the world’s migratory birds and a broad range of endangered mammal, reptile, amphibian, and plant species. They provide a broad range of flood storage, pollution control, water supply, ecotourism functions to indigenous peoples and country populations as a whole. They are also at the center of severe land and water use conflicts. These are conflicts between counties where wetland resources or the water supplies required for such resources involve more than one country. These are conflicts in use such as conflicts between habitat protection and charcoal production in mangroves. These are conflicts between groups of peoples such as indigenous peoples and hydropower advocates. Many wetlands have already been destroyed by water extractions, dams, levees, channelization, and fills. Others have been degraded by water pollution, overfishing and overhunting, timber harvest, and a host of other activities. This book describes these conflicts and international policies and institutions developed to protect and manage wetland resources. Most of the broader literature and other books on wetlands focuses on wildlife. Wildlife is described in the case studies, which follow. But, Richard Smardon provides us with more. He traces the history of conflicts and the development of policies and insti- tions to protect and manage wetland resources.
Download or read book Global Soil Biodiversity Atlas written by European Commission. Joint Research Centre and published by . This book was released on 2016 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Atlas describes soil as habitat for the diversity of organisms that live under our feet. At the same time, it draws attention to the threats to soil biodiversity, such as invasive species, pollution, intensive land use practices or climate change. The Atlas provides current solutions for a sustainable management of soils. It was coordinated by the JRC and the Global Soil Biodiversity Initiative (www.globalsoilbiodiversity.org) with more than 70 contributing organisations and several hundred individual contributions. It illustrates the diversity of soil organisms, explains their geographical and temporal distribution, the ecosystem functions and services provided by soil biota. Most importantly, it draws attention to the myriad of threats to soil biodiversity. These include inappropriate land management practices (e.g. deforestation, land take for infrastructure development), agricultural systems, over-grazing, forest fires and poor water management (both irrigation and drainage). Other practices such as land conversion from grassland or forest to cropped land result in rapid loss of soil carbon, which indirectly enhances global warming. The Atlas shows that mismanaging soils could exacerbate the effects of climate change, jeopardise agricultural production, compromise the quality of ground water and worsen pollution. It also proposes solutions to safeguard soil biodiversity through the development of policies that directly or indirectly target soil health, leading to a more sustainable use."--
