Economic Policy and Sustainable Land Use
Author: Nico Heerink
Publisher: Springer Science & Business Media
ISBN: 3642575587
Category : Business & Economics
Languages : en
Pages : 388
Book Description
Since the 1980s many developing countries have implemented macro-economic policy reforms to curb inflation, reduce fiscal deficits and control foreign debt. The policy instruments used, such as exchange rate adjustment, budget cuts, trade policy reforms, public expenditure reviews and privatisation, have different and sometimes opposite consequences for agricultural land use. During the same period awareness was growing that deteriorating soil quality could become a limiting factor to increase or even sustain agricultural production. As a result, food availability and even accessibility for large population groups in developing countries may be jeopardised in the near future. Recently, quantitative models have made useful contributions to understanding the impact of economic policy reforms on the sustainability of land use. They provide a consistent analytical framework to deal with complex issues such as the direct and indirect effects of economic, agricultural, environmental and population policies, the role of market imperfections in transmitting economic policy signals, and the interactions between soil quality, agricultural production and household economic decision making. Different types of models can be distinguished: bio economic models, focussing on the link between farm household decisions and the agricultural resource base, household and village models, examining the impact of the socio-economic environment on farm household decisions, and more aggregate models, analysing interactions between sectors and their implications for sustainable land use.

Late Cenozoic of Península Valdés, Patagonia, Argentina
Author: Pablo Bouza
Publisher: Springer
ISBN: 3319485083
Category : Science
Languages : en
Pages : 314
Book Description
This book presents extensive and new information on the Cenozoic marine and continental systems of one of the most important World Heritage sites of Southern South America: The Península Valdés. Using an interdisciplinary approach, that includes geological, biological and archeological perspectives of more than 30 specialists, an integrated description and analysis of the Cenozoic environments of the study region is presented. The volume brings together an update of the geology, climate, geomorphology, soils, biodiversity, archeology and human impact of the Península Valdés. The scope of this book extends to any natural science researcher of the world interested on the Cenozoic history of the Península Valdés.

New Models for Ecosystem Dynamics and Restoration
Author: Richard J. Hobbs
Publisher: Island Press
ISBN: 1610911385
Category : Science
Languages : en
Pages : 366
Book Description
As scientific understanding about ecological processes has grown, the idea that ecosystem dynamics are complex, nonlinear, and often unpredictable has gained prominence. Of particular importance is the idea that rather than following an inevitable progression toward an ultimate endpoint, some ecosystems may occur in a number of states depending on past and present ecological conditions. The emerging idea of “restoration thresholds” also enables scientists to recognize when ecological systems are likely to recover on their own and when active restoration efforts are needed. Conceptual models based on alternative stable states and restoration thresholds can help inform restoration efforts. New Models for Ecosystem Dynamics and Restoration brings together leading experts from around the world to explore how conceptual models of ecosystem dynamics can be applied to the recovery of degraded systems and how recent advances in our understanding of ecosystem and landscape dynamics can be translated into conceptual and practical frameworks for restoration. In the first part of the book, background chapters present and discuss the basic concepts and models and explore the implications of new scientific research on restoration practice. The second part considers the dynamics and restoration of different ecosystems, ranging from arid lands to grasslands, woodlands, and savannahs, to forests and wetlands, to production landscapes. A summary chapter by the editors discusses the implications of theory and practice of the ideas described in preceding chapters. New Models for Ecosystem Dynamics and Restoration aims to widen the scope and increase the application of threshold models by critiquing their application in a wide range of ecosystem types. It will also help scientists and restorationists correctly diagnose ecosystem damage, identify restoration thresholds, and develop corrective methodologies that can overcome such thresholds.
