ISBN: 9783540001850
Category : Science
Languages : en
Pages : 424
Book Description
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

The Science and Practice of Resilience
Author: Igor LinkovPublisher: Springer
ISBN: 303004565X
Category : Technology & Engineering
Languages : en
Pages : 212
Book Description
This book offers a comprehensive view on resilience based upon state-of-the-science theories and methodological applications that resilience may fill. Specifically, this text provides a compendium of knowledge on the theory, methods, and practice of resilience across a variety of country and case contexts, and demonstrates how a resilience-based approach can help further improved infrastructure, vibrant societies, and sustainable environments and ecologies, among many others. Resilience is a term with thousands of years of history. Only recently has resilience been applied to the management of complex interconnected systems, yet its impact as a governing philosophy and an engineering practice has been pronounced. Colloquially, resilience has been used as a synonym for ‘bouncing back’. Philosophically and methodologically, however, it is much more. In a world defined by interconnected and interdependent systems such as water, food, energy, transportation, and the internet, a sudden and unexpected disruption to one critical system can lead to significant challenges for many others. The Science and Practice of Resilience is beneficial for those seeking to gain a rich knowledge of the resilience world, as well as for practitioners looking for methods and tools by which resilience may be applied in real-world contexts.

Ocean Biogeochemistry
Author: Michael J.R. FashamPublisher: Springer Science & Business Media
ISBN: 3642558445
Category : Science
Languages : en
Pages : 324
Book Description
Oceans account for 50% of the anthropogenic CO2 released into the atmosphere. During the past 15 years an international programme, the Joint Global Ocean Flux Study (JGOFS), has been studying the ocean carbon cycle to quantify and model the biological and physical processes whereby CO2 is pumped from the ocean's surface to the depths of the ocean, where it can remain for hundreds of years. This project is one of the largest multi-disciplinary studies of the oceans ever carried out and this book synthesises the results. It covers all aspects of the topic ranging from air-sea exchange with CO2, the role of physical mixing, the uptake of CO2 by marine algae, the fluxes of carbon and nitrogen through the marine food chain to the subsequent export of carbon to the depths of the ocean. Special emphasis is laid on predicting future climatic change.
France in the South Pacific
Author: Denise FisherPublisher: ANU E Press
ISBN: 1922144959
Category : History
Languages : en
Pages : 366
Book Description
France is a Pacific power, with three territories, a military presence, and extensive investments. Once seen by many as a colonial interloper in the South Pacific, by the early 2000s, after it ended nuclear testing in French Polynesia and negotiated transitional Accords responding to independence demands in New Caledonia, France seems to have become generally accepted as a regional partner, even if its efforts concentrate on its own territories rather than the independent island states. But Frances future in the region has yet to be secured. By 2014 it is to have handed over a set of agreed autonomies to the New Caledonian government, before an independence referendum process begins. Past experience suggests that a final resolution of the status of New Caledonia will be divisive and could lead once again to violent confrontations. In French Polynesia, calls continue for independence and for treatment under UN decolonisation procedures, which France opposes. Other island leaders are watching, so far putting faith in the Noumea Accord, but wary of the final stages. The issues and possible solutions are more complex than the French Pacific island population of 515,000 would suggest. Combining historical background with political and economic analysis, this comprehensive study offers vital insight into the intricate history -- and problematic future -- of several of Australias key neighbours in the Pacific and to the priorities and options of the European country that still rules them. It is aimed at policy-makers, scholars, journalists, businesspeople, and others who want to familiarise themselves with the issues as Frances role in the region is redefined in the years to come.
Strategic Asset Management of Water Supply and Wastewater Infrastructures
Author: Helena AlegrePublisher: IWA Publishing
ISBN: 1843391864
Category : Science
Languages : en
Pages : 553
Book Description
Water and Wastewater companies operating all around the world have faced rising asset management and replacement costs, often to levels that are financially unsustainable. Management of investment needs, while meeting regulatory and other goals, has required: A better understanding of what customers demand from the services they pay for, and the extent to which they are willing to pay for improvements or be compensated for a reduction in performance Development of models to predict asset failure and to identify and concentrate investment on critical assets Improved management systems Improved accounting for costs and benefits and their incorporation within an appropriate cost-benefit framework Incorporation of risk management techniques Utilisation of advanced maintenance techniques including new rehabilitation failure detection technologies Enhancements in pipeline materials, technologies and laying techniques. These papers developed from LESAM 2007 for inclusion in Strategic Asset Management of Water Supply and Wastewater Infrastructures are focused on the techniques, technologies and management approaches aiming at optimising the investment in infrastructure while achieving demanded customer service standards, and they provide an opportunity to gain access to the latest discussion and developments at the leading-edge in this field. This book will be essential reading for utility operators and managers, regulators and consultants.

Mining in Africa
Author: Bonnie CampbellPublisher: IDRC
ISBN: 074532939X
Category : Business & Economics
Languages : en
Pages : 290
Book Description
The continent of Africa is rich in minerals needed by Western economies, but rather than forming the basis for economic growth the mining industry contributes very little to African development Investigating the impact of the 2003 Extractive Industries Review on a number of African countries, the contributors find the root of the problem in the controls imposed on the African countries by the IMF and World Bank. They aim to convince academics, governments and industry that regulation needs to be reformed to create a mining industry favourable towards social, economic and environmental development. The book takes a multidisciplinary approach and provides a historical perspective of each country, making it ideal for students of development studies and development organizations.
