  • Scientists predict the earth is facing 40-to-60 years of climate change, even if emissions of carbon dioxide and other global warming gases stopped today. One inevitable consequence of the greenhouse gases already in the atmosphere will be an increase in the frequency and severity of natural disaster events. Global Warming, Natural Hazards, and Emergency Management documents the imperative need for communities to prepare for the coming effects of climate change and provides a series of in-depth, road-tested recommendations on how to reduce risks for communities and businesses.

  • Natural resources conservation is one of the dilemmas currently facing mankind in both developed and the developing world. The topic is of particular importance for the latter, where the majority depend on terrestrial ecosystems for livelihood; more than one billion people live in abject poverty earning less than a dollar per day; more than 3.7 billion suffer from micronutrient deficiency and more than 800 million suffer from chronic hunger.

  • An analysis of the complex relationship between demographic changes and impacts on the natural-resource base confirms that resource exploitation is occurring not only to meet growing domestic needs but also for other vested interests. Population, together with other major drivers, such as institutions, markets, and technology, will have a very strong bearing on the way in which the rich resources of the Mekong River Basin are developed and distributed in the present and future.

  • Clay and clay minerals represent the youngest minerals in the Earth’s crust. Clays are irregularly distributed in lithosphere, as their concentration increases due to the weathering, hydrothermal changes, including anthropogenic influences. Clay minerals occur in all types of sediments and sedimentary rocks and are common in hydrothermal deposits. The interdisciplinary character of clay science follows from the information obtained from the methodology and theory of other natural and technical sciences....

  • This book provides an interdisciplinary view of how to prepare the ecological and socio-economic systems to the reality of climate change. Scientifically sound tools are needed to predict its effects on regional, rather than global, scales, as it is the level at which socio-economic plans are designed and natural ecosystem reacts. The first section of this book describes a series of methods and models to downscale the global predictions of climate change, estimate its effects on biophysical systems and monitor the changes as they occur....

  • Natural gas is a vital component of the world's supply of energy and an important source of many bulk chemicals and speciality chemicals. It is one of the cleanest, safest, and most useful of all energy sources, and helps to meet the world’s rising demand for cleaner energy into the future. However, exploring, producing and bringing gas to the user or converting gas into desired chemicals is a systematical engineering project, and every step requires thorough understanding of gas and the surrounding environment.

  • This is probably the first study that has used resilience, the adaptive cycle and panarchy as a major part of the conceptual foundation for the work. Resilience (as used here) has been explored in the literature for about 30 years, the adaptive cycle originated about 18 years ago and both have been integrated within the panarchy concept for only a few years.

  • Over the past three decades, governments at the local, state, and federal levels have undertaken a wide range of bold innovations, often in partnership with nongovernmental organizations and communities, to try to address their environmental and natural resource management tasks. Many of these efforts have failed. Innovations, by definition, are transitory. How, then, can we establish new practices that endure?
