Bioeconomic Modeling of Natural Resource Management

Pages : 96
Book Description
Economic progress and ecological balance always have conflicting interests. The necessities and comforts of human beings, invariably robs the ecological structure, of the nature. One such activity is harvesting. This, more often than not, leads to the extinction of a species of life. The exploitation of fish populations provides some classic examples of disastrous exploitation of renewable resources. Often it is possible to prevent such extinction by proper management. If a particular species is on the brink of extinction, then a properly planned regulating policy ensures the damage to the ecosystem is minimal and saves it from the extinction.This book provides an insight into the conservation and management aspects of the fishery, which is largely unregulated. Four different models are introduced, considering taxation as a control instrument and gompertz model. Also realistic catch rate, Stability, and optimal harvest policy is thoroughly analyzed.So this book will be a great help to the biologists, conservationists, scientists, researchers and anyone, who takes keen interest in the field of conservation and management of natural resources.
Fisheries Bioeconomics
Author: J. C. SeijoPublisher: Food & Agriculture Org.
ISBN: 9789251040454
Category : Biology, Economic
Languages : en
Pages : 128
Book Description
This book is presented in seven Chapters. Chapter 1 describes the basic assumptions underlying the optimal allocation of natural resources and the inherent characteristics of fisheries that determine, under unrestricted access, the failure to allocate resources, economic inefficiency and overfishing. To mitigate these undesired effects, the bioeconomic literature invokes the allocation of property rights, which in turn must be implemented within a management context. Thus, in this Chapter we suggest some guidelines to conduct management plans. Static and dynamic bioeconomic models are presented in Chapter 2 as a theoretical framework for the design of intelligent management schemes aiming at sustainable use of fish stocks. Classic models are shown, such as the Gordon-Schaefer based on the logistic. We also develop new bioeconomic approaches, such as a distributed-delay model to add realism to Smith's fleet dynamics approach. Chapter 2 also includes an introductory version of a bioeconomic yield-mortality model, and dynamic age-structured models. A comparison of the dynamic and static trajectories is stressed. The price of time and its implications for optimal resource allocation over time is also discussed. For the sake of adding realism to the above models, the systems approach is used in Chapter 3 to model different technological and ecological complexities that occur in marine fisheries. Ecological interdependencies (competition, predation), as well as technological interdependencies resulting from fleets with different fishing power and/or gear types, operating on components of a stock, or on different target species of a "mixed stock", are specified and modelled.
Natural Resources Management in Agriculture
Author: Bekele ShiferawPublisher: CABI
ISBN: 0851990681
Category : Business & Economics
Languages : en
Pages : 400
Book Description
In response to increasing concerns about the degradation of natural resources and the sustainability of agriculture, many research programmes have been established in natural resource management (NRM). However, although methods for evaluating the impacts of crop improvement technologies are well developed, there is a dearth of methods for evaluating the impacts of NRM interventions. This is partly due to the complexity of interactions among natural resources, spatial and temporal dimensions of impact, and the valuation of direct and indirect environmental costs and benefits. This book discusses the unique features and methodological difficulties of NRM impact assessment. It examines the strengths and weaknesses of various impact assessment approaches, including econometric, bio-economic, and more direct methods. It also assesses and identifies data requirements for developing impact indicators and recommends suitable methodologies for assessing the impacts of NRM technologies on issues such as soil and water conservation and watershed and biodiversity management.
Bioeconomics of Fisheries Management
Author: Lee G. AndersonPublisher: John Wiley & Sons
ISBN: 1119949246
Category : Technology & Engineering
Languages : en
Pages : 320
Book Description
Fisheries Economics has always been an interdisciplinary field of study with economic analysis based on stock population dynamics, but many published works have focused mainly on theoretical economic issues without much focus on biological details. For the most part, age structured models have been ignored. Bioeconomics of Fisheries Management is a valuable reference text that presents the economic aspects of fisheries management in a broad bioeconomic framework. The book is broken into two parts. Part I covers the traditional areas of fisheries economics, covering topics such as open access, optimal and managed fisheries utilization that is analyzed through a traditional one stock/one fleet model. It also presents the basic results in terms of an age structured model. Part II covers material related to more recent work on bioeconomic models when more rigorous biological components became more prevalent, and views fisheries management with an ecosystems-based approach. Accompanying the book is a user-friendly CD with exercises and examples that aids the reader in applying theoretical principles of population dynamics and fisheries management and regulation. Bioeconomics of Fisheries Management will be a valuable text for researchers, fisheries economists, professionals, and students alike.
Applied Mathematical Ecology
Author: Simon A. LevinPublisher: Springer Science & Business Media
ISBN: 3642613179
Category : Mathematics
Languages : en
Pages : 498
Book Description
The Second Autumn Course on Mathematical Ecology was held at the Intern ational Centre for Theoretical Physics in Trieste, Italy in November and December of 1986. During the four year period that had elapsed since the First Autumn Course on Mathematical Ecology, sufficient progress had been made in applied mathemat ical ecology to merit tilting the balance maintained between theoretical aspects and applications in the 1982 Course toward applications. The course format, while similar to that of the first Autumn Course on Mathematical Ecology, consequently focused upon applications of mathematical ecology. Current areas of application are almost as diverse as the spectrum covered by ecology. The topiys of this book reflect this diversity and were chosen because of perceived interest and utility to developing countries. Topical lectures began with foundational material mostly derived from Math ematical Ecology: An Introduction (a compilation of the lectures of the 1982 course published by Springer-Verlag in this series, Volume 17) and, when possible, progressed to the frontiers of research. In addition to the course lectures, workshops were arranged for small groups to supplement and enhance the learning experience. Other perspectives were provided through presentations by course participants and speakers at the associated Research Conference. Many of the research papers are in a companion volume, Mathematical Ecology: Proceedings Trieste 1986, published by World Scientific Press in 1988. This book is structured primarily by application area. Part II provides an introduction to mathematical and statistical applications in resource management.
Bioeconomic Modelling and Valuation of Exploited Marine Ecosystems
Author: J.C.J.M. van den BerghPublisher: Springer Science & Business Media
ISBN: 1402040598
Category : Business & Economics
Languages : en
Pages : 261
Book Description
This book offers an environmental-economic analysis of exploited ecosystems with a clear policy orientation. The study moves beyond traditional economic fishery analysis in two respects. First, several theoretical and numerical models are offered that combine economic and ecological descriptions of fisheries. Second, valuation and stakeholder concerns are addressed in empirical analyses employing both qualitative and quantitative approaches. The approaches, models and policy insights are sufficiently general and innovative to interest a broad audience.
