Biofuels, Solar and Wind as Renewable Energy Systems
The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided...
Environmental Management in Practice: Compartments, stressors and sectors
Volume 2: Compartments, Stressors and Sectors, deals with the problems that occur in the three 'compartments' of the environment, namely air, water and soil.
Environmental Management in Practice: Vol 2
Volume 2: Compartments, Stressors and Sectors, deals with the problems that occur in the three 'compartments' of the environment, namely air, water and soil. The contributors also address the socio-economic sectors of industry, traffic, energy, agriculture and tourism.
Invertebrate Biodiversity as Bioindicators of Sustainable Landscapes
Reducing environmental hazard and human impact on different ecosystems, with special emphasis on rural landscapes is the main topic of different environmental policies designed in developed countries and needed in most developing countries. This book covers the bioindication approach of rural landscapes and man managed ecosystems including both urbanised and industrialised ones. The main techniques and taxa used for bioindication are considered in detail. Remediation and contamination is faced with diversity, abundance and dominance of biota, mostly invertebrates. Invertebrate Biodiversity as Bioindicators of Sustainable Landscapes provides a basic tool for students and scientists involved in landscape ecology and planning, environmental sciences, landscape remediation and pollution.
Local Mediterranean Food Plants and Nutraceuticals
As a result of domestication - considered to be the most important cultural development of the past 13,000 years of human history - we depend today on a tiny number of domesticated plant and animal species for our food supply. Nevertheless, people continue to gather food which grows around their homes or they cultivate local varieties of food plants (as well as keep land races of domestic animals). Generally, wild varieties tend to be richer in micronutrients and bioactive secondary metabolites, which are produced in adaptation to local environmental conditions. These metabolites trigger further adaptive responses by producing 'protective', bioactive compounds which, when ingested, result in...
Structure and Function in Agroecosystem Design and Management
Structure and Function in Agroecosystem Design and Management presents an advanced discussion of the need to design agricultural systems that 1) increase reliance on biological interactions in agroecosystems as a means of decreasing dependence on the use of large quantities of agrochemicals and the consumption of fossil fuel energy and 2) continue
Ecosovereignty
In this book, Omar Dahbour develops the idea of ecosystem sovereignty, calling for a reinterpretation of some essential concepts in political philosophy, including territoriality, self-determination, peoplehood, and sovereignty, in order to make the case for peoples’ rights to protect and maintain their natural environments. In doing so, he theorizes current and historical struggles against resource extractions and land grabs, especially by food sovereignty and indigenous rights movements. The basic idea of ecosovereignty is that peoples living in relation to particular ecosystems have a collective right to ultimate authority over those systems and the resources they contain—provided the...
Soil and Water Conservation Policies and Programs
For as far into the future as we can see, governments will probably topple, power will continue to exchange hands, the climate will undergo continuous change, and the global economy will ebb and flow like the oceans. But for the world's many diverse countries-whether they be highly industrialized or third world-one thing will always remain constant: the need to solve the planet's pressing soil and water conservation problems, as well as implement effective policies. But why do some policy initiatives succeed while others fail? Soil and Water Conservation Policies and Programs: Successes and Failures addresses this very question. Based on an international conference held in Prague, this book ...
Agricultural Ecology and Environment
The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different discip...
Eat the Beetles!
“Provides a sturdy literary exoskeleton to the field of human insectivory . . . it entertains as it enlightens” (Daniella Martin, author of Edible). Meet the beetles: there are millions and millions of them and many fewer of the rest of us—mammals, birds, and reptiles. Since before recorded history, humans have eaten insects. While many get squeamish at the idea, entomophagy—people eating insects—is a possible way to ensure a sustainable and secure food supply for the eight billion of us on the planet. Once seen as the great enemy of human civilization, destroying our crops and spreading plagues, we now see insects as marvelous pollinators of our food crops and a potential source o...
