Ecohydrology of the Andes Páramo Region (IHE Delft PhD Thesis Series)

by Veronica G. Minaya Maldonado

In the Andes mountainous region of South America grasslands known as páramos provide important ecosystem services like sustaining biodiversity, securing carbon sequestration and providing water storage. However, many páramos regions are subject to land use change due to expanding agriculture, intensified grazing and land burning. These are usually caused by socio-economic factors driving local communities to increase their income generation. Trying to achieve a better understanding of the páramos is often restricted to exploring specific details and does not follow an integrated approach or a comprehensive ecosystem analysis. In this research the focus is on better understanding the dominant ecohydrological processes and their interactions. An integrated approach is followed using in-situ measurements, field experiments, laboratory analyses, and numerical modelling. Also, different hydroinformatics tools are used to identify and quantify the ecosystem services provided by the páramos. Moreover, a framework is developed that allows a more realistic quantification and mapping of the main ecosystem services. The approach was carried out for a test site in an Ecological area in North Ecuador. The findings show a clear difference in ecosystem services depending on their altitudinal range and type of vegetation. These results can be used to further develop environmental management and landscape planning strategies, in order to better meet the social goals. This research is aligned with the priorities advocated in the IPCC Report (2007) 'to improve representation of the interactive coupling between ecosystems and the climate system', and with SDG #15: Life on Land 'By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services'.

Ecolitan Prime: The Ecologic Envoy and The Ecolitan Enigma

by L. E. Modesitt Jr.

This new omnibus from L. E. Modesitt, Jr., includes the third and fourth of his four- volume Ecolitan series, The Ecologic Envoy and The Ecolitan Enigma, both starring Nathaniel Whaler.Four hundred years after winning secession from the Terran Empire (as chronicled in the earlier omnibus, Empire & Ecolitan), the star system Accord wants to sign a simple trade treaty with the Empire on microchip export tariffs. But if the agreement is so minor, why is Professor Nathaniel Whaler, chief economist at the Ecolitan Institute and his world's top commando killer, chosen as Accord's Envoy? Because the Imperial capital is a maddening bureaucracy of sniveling diplomats, high-profile figureheads, powers behind the throne, and spies---everywhere, spies. So the Envoy has to face red tape, politics, prejudice, as well as and a gauntlet of kidnappers, assassins, snipers, and bombs. And some ministry---but which?---doesn't want the treaty. In fact, some in the Empire still blame Accord for Earth's poisoning and for the defection of fifty star systems after the war between Imperial nuclear might and Ecolitan bio-ecological weaponry. A hidden cabal wants to fight that war again---even if, this time, the entire galaxy dies. And only Nathaniel Whaler, the Ecologic Envoy, has the power to stop the catastrophe. This omnibus concludes one of L. E. Modesitt's most powerful science fiction series.A shocking novel of what could happen if the fanatical defense of the environment crossed the line into deadly terror. When environmental consultant Jack McDarvid's boss is killed in a shootout near the Capitol, McDarvid becomes enmeshed in a diabolical plot behind the scenes of the environmental movement.Other Series by L.E.

Ecological Building Materials for Deserts and Drylands (SpringerBriefs in Geography)

by Daniela A. Ottmann

This book examines prospective climate adaptive building materials in desert and drylands in the context of climate change, desertification, urbanisation demands, and the consequent sustainable urban development challenges. This preliminary collection of ecological materials covers the characterisation of biotic and abiotic resources for materials, their specifications and benefits for adequate bio-climatic design and construction. Particular emphasis is given to ecological composite materials for advances in desert architecture. Based on the initial collection, the book culminates with potentials for new ecological building materials. The "eComposite Combinator" matrix offers potential research recipes and encourages the reader to conduct further climate-matters related research.

Ecological Connectivity of Forest Ecosystems

by Martin Braun Katharina Lapin Janine Oettel Heino Konrad

This is an open access book. This professional volume provides scientific background and practical guidance on forest management in light of ecological connectivity. Readers will gain a great understanding of shifting species in response to climate change and the resulting loss of various resources. The main drivers of these variations are the quality of the availability, quantity, and quality of habitats in the landscape, the genetic diversity of species populations, and the ability to navigate through a fragmented landscape matrix. The connectivity of habitats is gaining importance in the combat of both, the biodiversity crisis and the climate change crisis. Improving ecological connectivity, however, does not automatically benefit all species, as the examples described in the book demonstrate. Specific planning tools, active monitoring protocols, and management measures are needed to increase the benefit for species with low dispersal and small population size, which generally fail to migrate. Assisted migration can help to prevent species extinction, but also offer opportunities for pathogens to cross geographical barriers. The vast majority of the known diversity of plants, fungi, vertebrates, and invertebrates depends on forest ecosystems. This volume helps to spread this message and prepare students for their later careers in the forestry sector, while also informing active practitioners and policy makers.

Ecological Crisis, Sustainability and the Psychosocial Subject

by Matthew Adams

This book draws on recent developments across a range of perspectives including psychoanalysis, narrative studies, social practice theory, posthumanism and trans-species psychology, to establish a radical psychosocial alternative to mainstream understanding of 'environmental problems'. Only by addressing the psychological and social structures maintaining unsustainable societies might we glimpse the possibility of genuinely sustainable future. The challenges posed by the reality of human-caused 'environmental problems' are unprecedented. Understanding how we respond to knowledge of these problems is vital if we are to have a hope of meeting this challenge. Psychology and the social sciences have been drafted in to further this understanding, and inform interventions encouraging sustainable behaviour. However, to date, much of psychology has appeared happy to tinker with individual behaviour change, or encourage minor modifications in the social environment aimed at 'nudging' individual behaviour. As the ecological crisis deepens, it is increasingly recognised that mainstream understandings and interventions are inadequate to the collective threat posed by climate change and related ecological crises.

Ecological Economic and Socio Ecological Strategies for Forest Conservation: A Transdisciplinary Approach Focused on Chile and Brazil

by Felix Fuders Pablo J. Donoso

This book proposes strategies for improving the resilience and conservation of temperate forests in South America, such that these forests can provide ecosystem services in a sustainable way. As such it contributes to the design of a resilient human-forest model that takes into account the multiculturalism of local communities, in many cases including aspects of ecological economics, development economics and territorial development planning that are related to indigenous peoples or first nations. Further, it provides proposals for public and territorial policies that improve the state of conservation of native forests and forest ecosystems, based on a critical analysis of the economic factors that lead to the degradation of forest ecosystems in South America today. This edition was conceived by members of the Transdisciplinary Research Center for Social and Ecological Strategies for Sustainable Forest Management in South America at the Universidad Austral de Chile. It includes contributions by distinguished researchers from around the world, combining the fields of economics, ecology, biology, anthropology, sociology and statistics. It is not, however, simply a collection of works written by authors from different disciplines, but rather each chapter is in itself transdisciplinary. This approach makes the book a unique contribution to enhancing social, managerial and political approaches to forestry management, helping to protect forest ecosystem services and make them more sustainable. This, in turn, will benefit local communities and society as a whole, by reducing the negative externalities of forestry management and enhancing future opportunities.

Ecological Engineering Design

by Robert A. Morgan Marty D. Matlock

Ecologically-sensitive building and landscape design is a broad, intrinsically interdisciplinary field. Existing books independently cover narrow aspects of ecological design in depth (hydrology, ecosystems, soils, flora and fauna, etc. ), but none of these books can boast of the integrated approach taken by this one. Drawing on the experience of the authors, this book begins to define explicit design methods for integrating consideration of ecosystem processes and services into every facet of land use design, management, and policy. The approach is to provide a prescriptive approach to ecosystem design based upon ecological engineering principles and practices. This book will include a novel collection of design methods for the non-built and built environments, linking landscape design explicitly to ecosystem services.

Ecological Forest Management

by Jerry F. Franklin K. Norman Johnson Debora L. Johnson

Fundamental changes have occurred in all aspects of forestry over the last 50 years, including the underlying science, societal expectations of forests and their management, and the evolution of a globalized economy. This textbook is an effort to comprehensively integrate this new knowledge of forest ecosystems and human concerns and needs into a management philosophy that is applicable to the vast majority of global forest lands. Ecological forest management (EFM) is focused on policies and practices that maintain the integrity of forest ecosystems while achieving environmental, economic, and cultural goals of human societies. EFM uses natural ecological models as its basis contrasting it with modern production forestry, which is based on agronomic models and constrained by required return-on-investment. The book concludes with an overview of how EFM can contribute to resolving major 21st century issues in forestry, including sustaining forest dependent societies.

Ecological Impacts of Tsunamis on Coastal Ecosystems

by Tohru Nakashizuka Jotaro Urabe

This book focuses on the ecological impacts of the Great East Japan Earthquake and resulting tsunamis, a rare and extremely large disturbance event, on various coastal ecosystems in Japan's Tohoku area, including sub-tidal and tidal animal communities, sand dune plant communities and coastal forests. The studies presented here describe not only how species and populations in these ecosystems were disturbed by the earthquake and tsunamis, but also how the communities have responded to the event and what types of anthropogenic activities will hamper their recovery processes. In the ecological sciences, it is often argued that large disturbances are critical to shaping community structures and biodiversity in local and regional habitats. However, our understanding of these roles remains limited, simply because there have been few opportunities to examine and address the ecological impacts of large disturbance events. The scale of the 2011 Great East Japan Earthquake makes it one of the largest hazards in the past 1000 years. Thus, this book provides a unique opportunity to advance our understanding of the ecological impacts of large and rare disturbances and the implications of these events in the conservation and management of coastal ecosystems. Following an outline of the Great East Japan Earthquake, the book's content is divided into two major parts. Part I reports on studies examining the ecological impacts of the tsunamis on sub-tidal and tidal animal communities, while Part II focuses on terrestrial plant communities in Japan's coastal Tohoku area. This book will benefit all scientists interested in the ecological impacts of large disturbances on aquatic and terrestrial ecosystems in general, and especially those who are interested in the ecological management of coastal ecosystems and Ecosystem based Disaster Risk Reduction (EcoDRR).

Ecological Intensification of Natural Resources for Sustainable Agriculture

by Ram Swaroop Meena Manoj Kumar Jhariya Arnab Banerjee

Ecological intensification involves using natural resources such as land, water, soil nutrients, and other biotic and abiotic variables in a sustainable way to achieve high performance and efficiency in agricultural yield with minimal damage to the agroecosystems. With increasing food demand there is high pressure on agricultural systems. The concept of ecological intensification presents the mechanisms of ensuring high agricultural productivity by restoration the soil health and landscape ecosystem services. The approach involves the replacement of anthropogenic inputs with eco-friendly and sustainable alternates. Effective ecological intensification requires an understanding of ecosystems services, ecosystem's components, and flow of resources in the agroecosystems. Also, awareness of land use patterns, socio-economic factors, and needs of the farmer community plays a crucial role. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape. The editors critically examined the status of ecological stress in agroecosystems and address the issue of ecological intensification for natural resources management. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the approaches that can be put in practice for poly-cropping systems and landscape-scale management to increase the stability of agricultural production systems to achieve ‘Ecological resilience’. It further discusses the role of farmer communities and the importance of their awareness about the issues. This book will be of interest to teachers, researchers, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, agronomy, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be a useful read for green future.

Ecological Interface Design

by Catherine M. Burns John Hajdukiewicz

Ecological Interface Design delivers the techniques and examples that provide you with a foundation to succeed in designing advanced display graphics. The opening chapters introduce the "art" of interface design by exposing the analytical methods behind designs, the most common graphical forms, and how these methods and forms are pulled together to create a complete design.The book then incorporates case studies that further emphasize techniques and results. Each example exemplifies a solution to a certain part of the EID puzzle. Some of the examples demonstrate the analysis phase, while others apply more scrutiny to graphical design. Each is unique, allowing allowing you to use them in the development of your own designs. The volume concludes with an analysis that connects ecological interface design with other common interface design methods, enabling you to better understand how to combine approaches in the creation of design solutions.

Ecological Modeling in Risk Assessment: Chemical Effects on Populations, Ecosystems, and Landscapes

by Scott Ferson Lev R. Ginzburg Steven M. Bartell Robert A. Pastorok

Expanding the risk assessment toolbox, this book provides a comprehensive and practical evaluation of specific ecological models for potential use in risk assessment. Ecological Modeling in Risk Assessment: Chemical Effects on Populations, Ecosystems, and Landscapes goes beyond current risk assessment practices for toxic chemicals as applied to individual-organism endpoints to describe ecological effects models useful at the population, ecosystem, and landscape levels. The authors demonstrate the utility of a set of ecological effects models, eventually improving the ecological relevance of risk assessments and making data collection more cost effective.

Ecological Modelling of River-Wetland Systems: A Case Study for the Abras de Mantequilla Wetland in Ecuador (IHE Delft PhD Thesis Series)

by Maria Gabriela Alvarez Mieles

Around 6% of the Earth's land surface is covered by wetlands. Wetlands play a key role in hydrological and biogeochemical cycles, delivering multiple benefits to society: sources of water supply, flood regulation, water purification, agriculture, fisheries, and biodiversity. Hence, wetland systems are of immense socio-economic as well as ecological importance. In this research, the focus was on the Abras de Mantequilla (AdM) wetland in the tropical coastal region of Ecuador, a RAMSAR site and case study area for the EU-FP7 WETwin project. The research in this thesis involves a combination of field data collection, multivariate analysis techniques, as well as numerical modelling studies. The goal was to explore the effects of changes in hydrological forcing on the hydrodynamic and ecohydraulic responses of the wetland. The study aims to contribute to the understanding of how a tropical river-wetland system functions in terms of hydrodynamics, water quality, primary production, and biotic communities. Spatial patterns of biotic communities and environmental variables are obtained as well as spatio-temporal variability of hydrodynamics, water quality, primary productivity and fish habitat-suitability conditions. In data scarce areas and countries with financial constraints, the combination of field measurements with numerical models was extremely useful and relevant, confirming that these techniques complement each other in obtaining a better understanding of the dynamics of freshwater river–wetland systems. Studies like the present research can be used to enhance awareness about the environmental services of wetlands and stimulate cooperation between all stakeholders in order to achieve more sustainable wetland management.
