The effects of the Brussels Sugar Convention of 1902 on various Latin American countries are analysed: domestic production, exports, imports and prices.


Resilience In Ecology And Belief, Ram Ranjan Aug 2007

Resilience In Ecology And Belief, Ram Ranjan

Ram Ranjan

TThis paper explores the crucial linkage between societal risk perception and the survival of threatened ecosystems exhibiting non-linear stock dynamics. Perception of risk over specie’s importance and over its survival chances may be subject to resilience and therefore may differ from actual risks. Whereas, ecosystems stand a better chance of survival if they aren’t stressed beyond their resilience thresholds. When an ecosystem’s sustainability and the subjective perception of risks of their loss are both influenced by the stock of a common natural resource, several resource management outcomes are possible, not all of which may ensure the sustainability of the ecosystem. …


From Sweet Potatoes To God Almighty: Roy Rappaport On Being A Hedgehog, Brian A. Hoey, Thomas E. Fricke Jul 2007

From Sweet Potatoes To God Almighty: Roy Rappaport On Being A Hedgehog, Brian A. Hoey, Thomas E. Fricke

Brian A. Hoey, Ph.D.

Recognized as a principal figure in ecological anthropology, Roy Rappaport is best known for his studyPigs for the Ancestors(1968). His work in the anthropology of religion has received less attention. Least acknowledged is Rappaport’s role in defining an “engaged” anthropology. Drawn from interviews Tom Fricke conducted with Rappaport in the year before his death in October 1997, this article gives insight into these three facets of his professional life. Beginning with an account of Rappaport’s fieldwork with the Tsembaga Maring, the discussion takes up his core themes, ideas that evolved out of his early field experience and with which he …


Achieving Economic And Ecological Resilience Through Natural Resource Management, Ram Ranjan Jul 2007

Achieving Economic And Ecological Resilience Through Natural Resource Management, Ram Ranjan

Ram Ranjan

Historically, the subsistence based lifestyles of small scale economies (SSEs) have avoided pushing the stock of their natural resources beyond thresholds where their resilience could be lost. However, rising frequencies of natural disasters coupled with a growing outside influence from the developed economies are increasingly putting pressure on the economic and natural resources of these societies. This paper explores the nature and role of inter-linkages between ecological and economic resilience in SSEs towards maintaining long term sustainability in the face of these external influences. It is shown that initial conditions associated with the stock of natural and physical capital could …


Patterns Of Ecosystem Fragmentation In Jabal Al-Akhdar, Libya: A Look At Landscape Ecology (In Arabic) , Mansour M. Elbabour Apr 2007

Patterns Of Ecosystem Fragmentation In Jabal Al-Akhdar, Libya: A Look At Landscape Ecology (In Arabic) , Mansour M. Elbabour

Mansour M Elbabour

Abstract Landscape fragmentation is a growing problem throughout the region of Jabal al-Akhdar in northeastern Libya where forest fragmentation has been a common occurrence in the past few decades. A greater part of the surviving shrub cover in the upper and lower terraces of Jabal al-Akhdar and their escarpments consist of isolated patches and disconnected corridors. The primary cause of fragmentation is agricultural development, especially clearing the land for dry farming. This paper presents some of the principles of landscape ecology as they pertain to the management of natural resources. A further aim is to enhance public awareness of the …


Empirical Analysis Of Poverty And Inequality In West Virginia, Hector Addison Jan 2007

Empirical Analysis Of Poverty And Inequality In West Virginia, Hector Addison

Hector Addison

Poverty and income inequality have attracted a lot of attention in recent literature and policy discussions. Using Ordinary Least Squares and Two stage least squares and cross sectional data for all counties in West Virginia, this study examines the determinants of poverty and income inequality and possibility of simultaneous relationship between them. Findings indicate there is a weak simultaneous relationship and income inequality is declining among aged 65 and above. Education, seen as social equalizer does not provide any evidence in reducing income inequality in West Virginia but as more and more women take up headship in families, poverty and …


Critical Examination Of Ghana’S Agriculture Policy Under Vision 2020 Document - Ppt, Hector Addison Jan 2007

Critical Examination Of Ghana’S Agriculture Policy Under Vision 2020 Document - Ppt, Hector Addison

Hector Addison

Ghana, like many developing economies has a huge agricultural based with cocoa being the major export commodity. Since independence in 1957, Ghana had struggled to put together and implement and model of development that guarantees better life for her citizenry. This paper looks at one such document and analyzes it from agriculture perspective in the context of present realities. It is clear that Ghana stands to gain from a transformed agricultural sector which might lead the way to discover the eluded glory as a resource endowed nation


Treatment Of Heavy Metals Contaminated Solid Wastes-Stabilization, Zeljko J. Kamberovic Jan 2007

Treatment Of Heavy Metals Contaminated Solid Wastes-Stabilization, Zeljko J. Kamberovic

Zeljko J Kamberovic

This paper presents investigation of possibility of heavy metals contaminated solid wastes treatment form Bor Site, Serbia. Presented remediation technology is stabilization, which can effectively reduce content of contaminants in the environment. As a representative of solid waste from investigated site Dam from the Bor copper sulphide ore flotation tailings was chosen. For stabilization of solid waste as stabilizing agenses foundry sand and lime were used. Experiments were conducted by leaching of mixture of solid samples and stabilizing agens or their mixture with sulphuric acid. Change of Cu, Fe, Pb and Zn concentration and change of pH and Eh value …

The Economics Of Ecology Journals, Ted C. Bergstrom, Carl T. Bergstrom

Ted C Bergstrom

Large commercial publishers charge dramatically higher prices to institutions than do non-profit publishers. These price differences do not reflect quality as measured by citation rate or pages. We discuss effect of prices and citations on number of library subscriptions and offer an explanation for why competition has not been able to erode the price difference between commercial and non profit journals.

Ecosystem Services And The Public Trust Doctrine: Working Change From Within, J.B. Ruhl Dec 2006

Ecosystem Services And The Public Trust Doctrine: Working Change From Within, J.B. Ruhl

J.B. Ruhl

What to do with the public trust doctrine? Environmental law scholars have been asking that question for going on 40 years, ever since Professor Joseph Sax surmised in his famous law journal article on the topic that of all the concepts known to American law, only the public trust doctrine seems to have the breadth and substantive content which might make it useful as a tool of general application for citizens seeking to develop a comprehensive legal approach to resource management problems. In this Article we briefly survey reasons why his vision has yet to be fulfilled, and we propose …
