Researchers in the natural sciences are faced with problems that require a novel approach to improve the quality of forecasts of processes that are sensitive to environmental conditions. Nonlinearity of a system may significantly complicate the predictability of future states: a small variation of parameters can dramatically change the dynamics, while sensitive dependence of the initial state may severely limit the predictability horizon. Uncertainties also play a role. This volume addresses such problems by using tools from chaos theory and systems theory, adapted for the analysis of problems in the environmental sciences. Sensitive dependence on the initial state (chaos) and the parameters are analyzed using methods such as Lyapunov exponents and Monte Carlo simulation. Uncertainty in the structure and the values of parameters of a model is studied in relation to processes that depend on the environmental conditions. These methods also apply to biology and economics. For research workers at universities and (semi)governmental institutes for the environment, agriculture, ecology, meteorology and water management, and theoretical economists.

When Franklin published her book on cyst nematodes in 1951, the cyst nematodes were already known as serious pests of brassicas, cereals, potatoes and sugar beets. However, at that time this group of nematode, with about 12 species, was considered tobe largely temperate in distribu tion. Now a total of 105 species (including those that are considered as synonyms or species inquirende by some or all) within six genera of cyst nematodes have been described from temperate, tropical, and subtropical regions and at least five species are important constraints to crop produc tion in tropical agriculture. The previous impression of localization of cyst nematodes in the temperate region was seemingly an artifact due to a greater concentration of nematologists in the temperate regions. Based on my own experience of working in several Asian and African countries, I believe that many more undescribed species are present in the tropical countries of Asia and Africa, and probably in other tropical regions. Most growers, extension workers, and research managers in these regions are still not aware of the possible harm of presence of these nematodes in their agricultural soils. The cyst nematodes are perhaps smaller than the smallest available computer chip but they are very well programmed to survive and pro pagate despite severe hardships. These nematodes are very selective in their choice of food; about 50% of known species are parasites of plants mainly in the families Poaceae and Fabaceae.

Regional Sustainability written by Irene Ring and has been published by Springer Science & Business Media this book supported file pdf, txt, epub, kindle and other format this book has been release on 2012-12-06 with Business & Economics categories.
This book presents interdisciplinary approaches towards achieving regional sustainability. The relevance of interdisciplinary research and its consequences for economic research into the environment are elaborated, and new approaches are developed to integrate knowledge from ecological and social sciences into economic research. Regional Sustainability includes the development of theoretical concepts as well as applied regional case studies relating to nature conservation and agricultural policies, coastal management and air pollution problems. Centered around the themes of decision-making processes, modelling as support for policy analysis and the evaluation of policies, it successfully addresses problems facing researchers and policy-makers in the context of regional sustainable development. The book pays special attention to human behaviour and stakeholders in decision-making processes, and contributes to the transition from ecological economics to socio-ecological economics.

Sensitivity analysis should be considered a pre-requisite for statistical model building in any scientific discipline where modelling takes place. For a non-expert, choosing the method of analysis for their model is complex, and depends on a number of factors. This book guides the non-expert through their problem in order to enable them to choose and apply the most appropriate method. It offers a review of the state-of-the-art in sensitivity analysis, and is suitable for a wide range of practitioners. It is focussed on the use of SIMLAB – a widely distributed freely-available sensitivity analysis software package developed by the authors – for solving problems in sensitivity analysis of statistical models. Other key features: Provides an accessible overview of the current most widely used methods for sensitivity analysis. Opens with a detailed worked example to explain the motivation behind the book. Includes a range of examples to help illustrate the concepts discussed. Focuses on implementation of the methods in the software SIMLAB - a freely-available sensitivity analysis software package developed by the authors. Contains a large number of references to sources for further reading. Authored by the leading authorities on sensitivity analysis.

Only a few laboratories in the world have taken the bold step to attempt the integration of sub-models of the climate system, the global biogeochemical cycles and the human/societal components. This volume reports such a major undertaking and it is an important step towards an integrated approach to global change science. The IMAGE 2 model is important in demonstrating our current ability to model the complex global system.

This book features a collection of extended papers based on presentations given at the SimHydro 2019 conference, held in Sophia Antipolis in June 2019 with the support of French Hydrotechnic Society (SHF), focusing on “Which models for extreme situations and crisis management?” Hydraulics and related disciplines are frequently applied in extreme situations that need to be understood accurately before implementing actions and defining appropriate mitigation measures. However, in such situations currently used models may be partly irrelevant due to factors like the new physical phenomena involved, the scale of the processes, and the hypothesis included in the different numerical tools. The availability of computational resources and new capacities like GPU offers modellers the opportunity to explore various approaches to provide information for decision-makers. At the same time, the topic of crisis management has sparked interest from stakeholders who need to share a common understanding of a situation. Hydroinfomatics tools can provide essential information in crises; however, the design and integration of models in decision-support systems require further development and the engagement of various communities, such as first responders. In this context, methodologies, guidelines and standards are more and more in demand in order to ensure that the systems developed are efficient and sustainable. Exploring both the limitations and performance of current models, this book presents the latest developments based on new numerical schemes, high-performance computing, multiphysics and multiscale methods, as well as better integration of field-scale model data. As such, it will appeal to practitioners, stakeholders, researchers and engineers active in this field.

This book contains essays in honour of Claus Weddepohl who, after 22 years, is retiring as professor of mathematical economics at the Department of Quantitative Economics of the University of Amsterdam. Claus Weddepohl may be viewed as th~ first Dutch mathematical economist in the general equi librium tradition of Arrow, Debreu and Hahn. The essays in this book are centered around the themes Equilibrium, Markets and Dynamics, that have been at the heart of Weddepohl's work on mathematical economics for more than three decades. The essays have been classified according to these three themes. Admittedly such a classification always is somewhat arbitrary, and most essays would in fact fit into two or even all three themes. The essays have been written by international as well as Dutch friends and colleagues including Weddepohl's former Ph. D. students. The book starts with a review of Claus Weddepohl's work by Roald Ramer, who has been working with him in Amsterdam for all those years. The review describes how Weddepohl became fascinated by general equilibrium theory in the early stages of his career, how he has been working on the theory of markets throughout his career, and how he turned to applications of nonlinear dynamics to price adjustment processes in a later stage of his career. The first part of the book, Equilibrium, collects essays with general equilib rium theory as the main theme.
