Over the last 11,700 years, during which human civilization developed, the earth has existed within what geologists refer to as the Holocene Epoch. Now science is telling us that the Holocene Epoch in the geological time scale ended, replaced by the onset of a new, more dangerous Anthropocene Epoch, which began around 1950. The Anthropocene Epoch is characterized by an “anthropogenic rift” in the biological cycles of the Earth System, marking a changed reality in which human activities are now the main geological force impacting the earth as a whole, generating at the same time an existential crisis for the world’s population. What caused this massive shift in the history of the earth? In this comprehensive study, John Bellamy Foster tells us that a globalized system of capital accumulation has induced humanity to foul its own nest. The result is a planetary emergency that threatens all present and future generations, throwing into question the continuation of civilization and ultimately the very survival of humanity itself. Only by addressing the social aspects of the current planetary emergency, exploring the theoretical, historical, and practical dimensions of the capitalism’s alteration of the planetary environment, is it possible to develop the ecological and social resources for a new journey of hope.

Systems Analysis and Modeling in Food and Agriculture is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Systems analysis and modeling is being used increasingly in understanding and solving problems in food and agriculture. The purpose of systems analysis is to support decisions by emphasizing the interactions of processes and components within a system. Frequently investigated systems level questions in agriculture and food are relevant to the 6 E's: Environment, Energy, Ecology, Economics, Education, and Efficiency. The theme on Systems Analysis and Modeling in Food and Agriculture with contributions from distinguished experts in the field provides information on key topics related to food and agricultural system. The coverage include an overview of food system; system level aspects related to energy, environment, and social/policy issues; knowledge bases and decision support; computer models for crops, food processing, water resources, and agricultural meteorology; collection and analysis methods for data from field experiments; use of models and information systems. This volume is aimed at the following a wide spectrum of audiences from the merely curious to those seeking in-depth knowledge: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

a theoretical and practical critique of the methods (net energy analysis and Energy Return On Investment - EROI) so far proposed to assess the quality of energy sources a critical appraisal of existing energy statistics explaining their shortcomings presents an innovative approach capable of generating flexible protocols of energy accounting (to be tailored on the specificity of different situations) across scales

With its lush wetlands, miles of beaches, and wide array of colorful wildlife, Florida is a fascinating and important ecosystem to study. Using this state as a model, Environment and Society in Florida offers a whole systems approach to understanding the environment and discusses the interactions between human systems and natural systems. It addresses the complicated issues stemming from these interactions among population, resources, economics, and environment, and discusses how we may better manage these challenges in the future.

Urban areas produce a series of environmental problems arising from the consumption of natural resources and the consequent generation of waste and pollution. These problems contribute to the development of social and economic imbalances. All these problems, which continue to grow in our society, require new solutions. This book addresses the many inter-related aspects of the urban environment from transport and mobility to social exclusion and crime prevention. Publishing papers from the Fourth International Conference on Urban Regeneration and Sustainability, the volume includes topics such as: Strategy and Development; Planning; Development and Management; Environmental Management; Planning Issues; Socio-economic Issues; The community and the City; Cultural Heritage; Architectural Issues; Traffic and Transportation; Land Use and Management; Public Safety; Conservation of Resources; Sustainable Transportation and Transport Integration; Depleted Ecological Resources; Environmental Pollution; Energy Resources Systems.

The Environmental Monitoring and Assessment Program was created by EPA to develop the capability for tracking the changing conditions of our natural resources and to give environmental policy the advantages ofa sound scientific understanding of trends. Former EPA Administrators recognized early that contemporary monitoring programs could not even quantify simple unknowns like the number of lakes suffering from acid rain, let along determine if national control policies were benefiting these lakes. Today, adding to acidification impacts are truly complex problems such as determining the effects of climate change, of increases in ultraviolet light, toxic chemicals, eutrophication and critical habitat loss. Also today, the Government Performance and Results Act seeks to have agencies develop performance standards based on results rather than simply on levels of programmatic activities. The charge to EMAP of ecosystems is, therefore, the same today as it was a with respect to measuring the condition decade ago. We welcome the increasing urgency for sound scientific monitoring methods and data by efforts to protect and improve the environment. Systematic nationwide monitoring of natural resources is more than anyone program can accomplish, however. In an era of declining budgets, it is crucial that monitoring programs at all levels of government coordinate and share environmental data. EMAP resources are dwarfed by the more than $500 million spent on federal monitoring activities each year.

Much of the convenience of modern life resides in sheet metal, the cowling shield of most machines and appliances. However, the load that this takes off human shoulders has to be carried elsewhere, and the Earth has borne the burden. Many of us woke up to the environmental cost when over a century of industrialization finally surpassed the capacity
