Book Description
Process-based models open the way to useful predictions of the future growth rate of forests and provide a means of assessing the probable effects of variations in climate and management on forest productivity. As such they have the potential to overcome the limitations of conventional forest growth and yield models, which are based on mensuration data and assume that climate and atmospheric CO2 concentrations will be the same in the future as they are now. This book discusses the basic physiological processes that determine the growth of plants, the way they are affected by environmental factors and how we can improve processes that are well-understood such as growth from leaf to stand level and productivity. A theme that runs through the book is integration to show a clear relationship between photosynthesis, respiration, plant nutrient requirements, transpiration, water relations and other factors affecting plant growth that are often looked at separately. This integrated approach will provide the most comprehensive source for process-based modelling, which is valuable to ecologists, plant physiologists, forest planners and environmental scientists. - Includes explanations of inherently mathematical models, aided by the use of graphs and diagrams illustrating causal interactions and by examples implemented as Excel spreadsheets - Uses a process-based model as a framework for explaining the mechanisms underlying plant growth - Integrated approach provides a clear and relatively simple treatment

Book Description
Therapists are increasingly using a variety of techniques in their clinical practice. From memory recovery to relaxation training, from cognitive restructuring to empathic reflection, today's interventions are based less on the theoretical preconceptions of the therapist and more on the problems and desires of the patient. With these changes as a backdrop, internationally renowned cognitive psychologist Hector Fernandez-Alvarez presents an integrated model of therapy. Theoretically sound and clinically rich, this volume offers a way of tailoring each clinical encounter to the needs of the particular patient, from the mildy distressed anxiety disordered the severely suffering borderline. This book is an invaluable guide to students and experienced therapists alike.

Book Description
The green revolution in India about 50 years ago transformed India's image then as begging bowl to bread basket. This transformation during the 1960s took just about 4 years. The yield increases achieved in wheat and then in rice which occurred in just about half decade is far in excess of the yield increases during the preceding 4000 years. This remarkable feat was achieved with the leadership of the author using the dwarf wheat types which had been produced by Norman Borlaug in Mexico. The research and development of green revolution of wheat and rice at the Indian Agricultural Research Institute, New Delhi was led by the author along with his team of students and co-workers. He has published over 100 papers on green revolution and the ever-green revolution which is a refinement of the former. This book is a compilation of just about 40 of his numerous research papers, monographs and books published by him on this subject. The papers in this book bring out the scientific basis of the modification of the plant type so as to be responsive to exogenous addition of chemical fertilizers and irrigation. The ideal plant type enables capture of adequate sunlight and using the chemical fertilizers added to the soil, produce substantial photosynthetic starch. And because the plants have short and thick culm, they are able to withstand enormous amounts of grains in their ears. This indeed was the basis of breaking the yield barriers associated with native varieties. The book also brings out that green revolution had established the food security at the national level but not at the individual household levels of millions of resource-poor rural small and marginal farming, fishing and landless families. Further green revolution was commodity-centric and the manner of its practice led to environmental degradation and social inequities. This author realized as early as 1972 that system of agriculture in India should be designed to fight both the famines of food and rural livelihoods. In pursuit of it, this author further designed an evergreen revolution with systems approach. What this means is providing concurrent attention to ecological foundations of agriculture and the livelihoods of the rural people. The book also brings out that green revolution was a team effort involving scientists, policy makers, administrators, farmers and students. This book is an outstanding example of green revolution providing a breathing space by putting the cereal grain production rate ahead of the population growth rate and then when food security has been adequately established, the system is changed to achieve productivity in perpetuity without causing environmental and social harm.

Book Description
Most eucalypts grow naturally on soils low in fertility. Commercial plantations of eucalypts have been established around the world over a range of climates and soils. These two themes are central to this book. Nutrition of Eucalypts provides a comprehensive survey of nutritional ecology of eucalypts in their natural environment and in plantations. The authors, who are all at the forefront of research and development in their fields, are from the various eucalypt growing regions including Brazil, India, China, Spain and Australia. Their text aims at a state-of-the-art presentation. The book includes a key and descriptions for recognising nutrient deficiencies in eucalypts.

Book Description
The dominant trees of Australia, eucalypts make up a remarkable genus. This authoritative volume provides current reviews by active researchers of many disciplines, including evolutionary history, genetics, distribution and modelling, the relationship of eucalypts to fire and nutrients, ecophysiology, pollination and reproductive ecology, interactions between eucalypts and other co-existing biota (including fungi, invertebrates and vertebrates), and conservation and management. Together these reviews shed light on the reasons for the great success of eucalypts in Australian environments, and provide a comprehensive summary for comparison with the ecology of major woody plant genera in other continents. This volume is of particular relevance to Australian ecologists, but also provides a stimulating perspective to students of vegetation ecology in all continents.

Book Description
How six industries are collaborating with competitors, society, and the public sector for competitive advantage No longer can we consume the equivalent of 1.3 Earths resources and expect to remain prosperous in perpetuity. We need a new economic paradigm, one that yields growth in a way that strengthens the global systems we rely on daily for survival, such as the global water, food, and energy systems. The Collaboration Economy—a model where the private, public, and civil sectors collaborate for prosperity that can last in perpetuity—is emerging. But what does this economic model look like? How does it work? How can companies survive and thrive in the Collaboration Economy? The Collaboration Economy provides easy to use frameworks and tools to enable leaders of industry, of government, and of society to lead the effort to align growth with sustainable development. Offers a plan for how the private, public, and civil sectors can successfully collaborate to steward resources, fortify global water, food, and energy systems, and spark a new era of prosperity at the same time Contains case study profiles of the leaders of the Collaboration Economy, including Unilever, GE, Coca-Cola, Nestle Waters North America, Grieg Green, and the European Parliament Written by Eric Lowitt, a globally recognized and sought after consultant, thought leader, and speaker in the fields of competitive strategy, growth, and sustainability, who has been named one of the Global Top 100 Thought Leaders on Trustworthy Business Behavior by Trust Across America
