Yet another book on the topic of 'Sustainable Forest Management' can only be justified by new information that is of direct relevance. The contents of this volume concentrate on the very latest factors and developments, thus, hopefully, contributing both to the book's attractiveness and to closing gaps in the discipline's database. This book is written for researchers in the field of forest management, international forestry, and climate change-related issues, legal and policy advisors, as well as for managers of private companies who deal with SFM. The authors of the various sections are scientists in the field of forestry and other environmental sciences. They represent different institutions, mainly universities and research agencies in Germany, but also high-level international institutions in development co-operation, such as the World Bank, FAO, and IIASA. The scope of the book is to refresh the meanings and perceptions of SFM against the background of the rapid changes in our natural and social environment. Climate change and the rapid increase of atmospheric CO concentration is a global process 2 with negative impacts of different kinds, among others on natural ecosystems such as forests. A crucial issue therefore is how forest management can contribute to forest conservation in light of changing climatic conditions. Moreover, policy changes such as the introduction of certification schemes and the new emphasis laid on Non-Wood Forest Products justify the re-evaluation of the role of SFM in delivering ecological goods and services from our forests.
As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high- latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.
Chlorophyll a Fluorescence: A Signature of Photosynthesis highlights chlorophyll (Chl) a fluorescence as a convenient, non-invasive, highly sensitive, rapid and quantitative probe of oxygenic photosynthesis. Thirty-one chapters, authored by 58 international experts, provide a solid foundation of the basic theory, as well as of the application of the rich information contained in the Chl a fluorescence signal as it relates to photosynthesis and plant productivity. Although the primary photochemical reactions of photosynthesis are highly efficient, a small fraction of absorbed photons escapes as Chl fluorescence, and this fraction varies with metabolic state, providing a basis for monitoring quantitatively various processes of photosynthesis. The book explains the mechanisms with which plants defend themselves against environmental stresses (excessive light, extreme temperatures, drought, hyper-osmolarity, heavy metals and UV). It also includes discussion on fluorescence imaging of leaves and cells and the remote sensing of Chl fluorescence from terrestrial, airborne, and satellite bases. The book is intended for use by graduate students, beginning researchers and advanced undergraduates in the areas of integrative plant biology, cellular and molecular biology, plant biology, biochemistry, biophysics, plant physiology, global ecology and agriculture.
This book entitled "Health and Environmental Issues That Shake The World" by Dr Paul Ola Igboji shows the authors love for man and the planet. According to the author, when High Immune Deficiency Syndrome (HIV) and Acquired Immune Deficiency Syndrome (AIDS) were discovered as sexually transmitted diseases that have no cure, the eyes of the world opened. Even before their discovery other ailments like Cancer, Sickle Cell Anaemia, Malaria, Typhoid, Cholera, Dysentary, Yellow Fever, Laser Fever, Tuberculosis, Asthma, Leprosy and a host of others have ravaged the world. Not quite long "Ebola" which is also incurable. Even though, some have remedies that tend to cure the disease or prolong life of patients like HIV but not AIDS, Cancer, Asthma, Leprosy; others like Ebola and Laser fever is yet to have cure. Others like Malaria, Cholera, Yellow Fever, Tuberculosis, Dysentary have been defeated through vaccination and drugs that are very successful. Other health and environmental issues that shake the world, according to this author include diabetes, influenza, small pox, Mumps, Measles and Rubella (MMR), migraines, cardiac, blood substitutes, smart pills, xenotransplantation, mental and emotional disorders, obesity, anorexia, genetic modification of plants, cloning of animal, gas poisoning, Viagra/drug abuse, endocrine disrupters, climate change, ozone layer depletion, global warming, rise in sea level, flooding/tsunami; desertification, drought; erosion, earthquake, landslides, tornado, hurricane. Human life is threatened on air, land and sea. Insecurity, fear, uncertainty, anxiety trail the blaze in life of human race. To crown it all, we have moved from era of cold war to that of global terrorism. The later has been very difficult as it cuts across regions, continents and countries and very difficult to control as terrorist are humans living and eating with one another innocently. Terrorists have no tomorrow in their dictionary. It is either today we perish or never and does not honour father, mother, wife, children, religion, state, leader, the led and any legislation or material on earth. Terrorists are greater than nuclear weapon as the latter's use can never be envisaged by any normal human being except in the case of Armageddon or nuclear accident. Moreover, the nuclear weapons being stored today may be black gold of future generations. Both the owner and user of nuclear weapon are bound to Hades or Hell Fire instantly once they are launched. In a world of uncertainty, panic, distrust, hate, religious divide, socio-cultural divide, political divides, economic divides, quest for supremacy, discrimination, apartheid, imperialism, borders, taboos, dogmas, molestations, abuse, betrayal, name it; we live on a keg of gunpowder ready to devour all. But, there remains a solution. NASA and other atheists now believe that God exist and have key to mysteries of the world. All the gods and satans we worship submit to only one true God that is omniscient, omnipresent and omnipotent, very fair, civil, descent, affordable, beneficial, adoring, kind, loving, charismatic, untouchable God that rules heaven and earth and has everything at his grip. He can reverse everything evil to good and restore world order, peace and togetherness. But, till he does, that many health and environmental issues; will continue to threaten the world. The book's contents are very delicious. It is a must read for everyone. Take a look!
The book that started it all: Before the Fall is sure to leave you interested in the inner-workings of poetry, pompous prose, pretentious descriptions and depictions, and really help you delve into the heart of the man that has written these things.
