The exclusive role of natural ecosystems is a key factor in the maintenance of the biospheric equilibrium. The current global crisis is largely caused by their dramatic decline by 43% in the past hundred years. Ignoring the immutable laws and limitations which determine the existence of all living things in the biosphere could lead humanity to an ecological catastrophe. This book presents the ecological, demographic, economic and socio-psychological manifestations of the global crisis and outlines the immutable laws and limitations which determine the existence of all living things in the...

2007 marked the 20th anniversary of the G.H.Brundtland Commission report that broke new ground by addressing the issue of sustainable development as a means of avoiding an ecological catastrophe. This led to a multitude of political declarations, documents and scientific articles while Agenda 21 adopted in 1992 in Rio de Janeiro has been accepted by the governments of more than 100 countries. Sadly, however, this has not prevented certain recent dangerous trends, nor have the wider public, journalists, business circles or politicians grasped the urgency of the problem. It is therefore...

Fire Ecology of Tropical Ecosystems gives an extensive explanation of historic and current fire situations in the tropics, describing the fire ecology of tropical ecosystems from around the globe. Eighteen groups of leading researchers explain the many different aspects and roles of fire in tropical ecosystems. Regional chapters address a set of common subjects including the causes of fire, typical fire behavior, and elements of the fire regime. In addition, they study the impacts of human land use, landscape fragmentation and climate change on the fire environment and the challenges of...

This book shows how human activity on local, regional and global scales has perturbed natural biogeochemical cycles, "colliding" with Nature. The authors demonstrate how the scale and intensity of human-induced destruction of Nature and resultant feedback mechanisms have continuously expanded. They consider the likelihood of increasing numbers of natural disasters as a result of such activities, and propose that sustainable development become a principal research topic for the 21st Century.

This book provides an account of recent developments in light scattering media optics. Leading researchers focus on both the theoretical and experimental results in the area. In particular, light scattering by ice crystals, soil particles and biological particles is considered. This volume first discusses single light scattering, followed by multiple light scattering and finally examines possible applications in combustion and marine research.

This book provides the first comprehensive analysis of how aerosols form in the atmosphere through in situ processes as well as via transport from the surface (dust storms, seas spray, biogenic emissions, forest fires etc.). Such an analysis has been followed by the consideration of both observation data (various field observational experiments) and numerical modeling results to assess climate impacts of aerosols bearing in mind that these impacts are the most significant uncertainty in studying natural and anthropogenic causes of climate change.

In its revised 2nd edition, this book examines current understanding of the relationship between sunspots and the Earth's climate. Opening with a brief historical review, the text moves on to scrutinize the various current hypotheses. The focus is on how information on the solar cycle and Earth's climate is gathered, and includes discussion of observations, methododology and the physics involved, with the necessary statistics and analysis also provided.

Large-scale natural catastrophes are environmental phenomena. Numerous studies in recent years have concluded that the frequency of occurrence of such natural disasters have been incereasing. leading to an enhanced risk of very considerable human and economic losses and the widespread destruction and pollution of habitats, settlements and infrastructure. In 2001 over 650 natural disasters happened around the globe with economic losses exceeding $35 billion. 2004 ended with the South East Asian tsunami on 26th December with its huge toll on life and local economics and this demonstrated...

Lakes Ladoga and Onego are the greatest lakes in Europe. With a surface area of 17891 km² and a volume of 902 km³, the former is one of the top fifteen world's freshwater lakes and is only slightly smaller than Lake Ontario. Lake Onego's surface area is 9600 km² and it has a volume of 292 km³. The watershed of Lake Ladoga (258000 km²) extends through Northwestern European Russia and the eastern part of Finland, including the large Lakes Ilmen and Saimaa, and together these Great European Lakes are an important link in the...
