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.
This new textbook has two main themes. The first is Modern Methods of Construction (MMC) which is the off-site manufacture of a wide spectrum of products, ranging from whole buildings to be transported onto site, down to smaller units or components for site integration. The second theme describes the innovation and progress towards carbon zero by the major generators of CO2 in the construction industry – namely cement, steel and masonry. The first section of the book describes and illustrates with photographs, the major forms of Modern Methods of Construction. These include fully completed 3D units, panelised systems, pods, sub-assemblies and on-site MMC. The section on Innovative Materials then describes a wide range of construction products which are entering into the built environment sector. Some new entrants are variants on well-established construction materials such as steel and concrete. Materials such as these will remain major construction materials for the foreseeable future, but their composition and manufacturing processes will inevitably have to change. Timber also will remain a major construction material, but sustainable sourcing is key and its utilisation as cross-lamination timber (CLT) or as modified timber is rapidly developing. As a result, students and practitioners must familiarise themselves with these materials, their composition, and various uses. The book goes on to describe variants of other traditional building products, such as glass, plastic and insulation, which are undergoing major developments leading towards enhanced environmental sustainability, as well as many emergent materials, some of which are likely to be significant in future. Modern Methods of Construction and Innovative Materials is the only book combining these important elements of the future of the industry in an easy-to-read guide for students and new practitioners. It is essential reading for anyone studying and working in the built environment, be they architects, construction managers, surveyors or engineers.
Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. - Highlights the complexity of global desert systems in a clear, concise way - Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change - Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems
Desiccation tolerance was essential when plants first began to conquer land, roughly 400 million years ago. While most desiccation-tolerant plants belong to basal phylogenetic taxa, this capacity has also evolved among some vascular plant species. In this volume renowned experts treat plant desiccation tolerance at the organismic as well as at the cellular level. The diversity of ecophysiological adaptations and acclimations of cyanobacteria, eukaryotic algae, mosses, and lichens is addressed in several chapters. The particular problems of vascular plants during dehydration/rehydration cycles resulting not only from their hydraulic architectures, but also from severe secondary stresses associated with the desiccated state are discussed. Based on the treatment of desiccation tolerance at the organismic level, a second section of the book is devoted to the cell biological level. It delineates the general concepts of functional genomics, epigenetics, genetics, molecular biology and the sensing and signalling networks of systems biology involved in dehydration/rehydration cycles. This book provides an invaluable compilation of current knowledge, which is a prerequisite for a better understanding of plant desiccation tolerance in natural as well as agro- and forest ecosystems where water is one of the most essential resources.
This book lays out a variety of practical ways to prepare for a changing climate by paying attention to soil, water harvesting, types of crops planted, and ways to protect pollinators.
Drylands have been cradles to some of the world’s greatest civilizations, and contemporary dryland communities feature rich and unique cultures. Dryland ecosystems support a surprising amount of biodiversity. Desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. Deterioration of soil and plant cover has adversely affected 70% of the world’s drylands as a result of extended droughts as well as mismanagement of range and cultivated lands. The situation is likely to worsen with high population growth rates and accompanying land-use conflicts. The contributions to The Future of Drylands – an international scientific conference held under the leadership of UNESCO – address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. Major themes include the conservation of dryland biological and cultural diversity and the human dryland interface. This volume documents how our improved understanding of drylands provides insight into the health and future prospects of these precious ecosystems that should help ensure that dryland communities enjoy a sustainable future.
Drylands cover 41 percent of the earth' s terrestrial surface. The urgency of and international response to climate change have given a new place to drylands in terms both of their vulnerability to predicted climate change impacts and their potential contribution to climate change mitigation. This book aims to apply the new scientific insights on complex dryland systems to practical options for development. A new dryland paradigm is built on the resources and capacities of dryland peoples, on new and emergent economic opportunities, on inward investment, and on the best support that dryland science can offer.
Taking a global perspective, this book provides a concise overviewof drylands, including their physical, biological, temporal, andhuman components. Examines the physical systems occurring in desert environments,including climate, hydrology, past and present lakes, weathering,hillslopes, geomorphic surfaces, water as a geomorphic agent, andaeolian processes Offers an accessible introduction to the physical, biological,temporal, and human components of drylands Investigates the nature, environmental requirements, andessential geomorphic roles of plants and animals in this stressfulbiological environment Highlights the impact of human population growth on climate,desertification, water resources, and dust storm activity Includes an examination of surface/atmosphere interactions andthe impact of ENSO events.
