A critical factor in the viability of such practices is socioeconomic and cultural acceptability in the communities of the region. Health is an essential factor in this dimension of sustainability. The NCE includes a health component that examines issues of human and ecosystem health related to boreal forest communities in western and northern Canada. These may be direct, involving direct health effects on the human body, or indirect, mediated by social mechanisms. Communities in the region are generally small, remote, limited in economic resources, and support a mixed economic development of forest products, oil and gas, and traditional aboriginal activities. The small and dispersed population and the time frame for the study do not permit application of the usual methods of broad-based community health research. Instead, emphasis is placed on four main elements with a variety of robust and sometimes qualitative methods to suit the problems. The four elements are: (1) ”Population health,“ a conceptual model of determinants of health, as interpreted for boreal forest communities; (2) application of the population health model to anticipate and prevent human health problems associated with various scenarios of sustainable forestry management; (3) occupational health and safety issues associated with increased activity in the forest products sector; and (4) large-scale ecosystem change and human health. The NCE presents an unusual opportunity to study both the ecosystem and human health implications of an ecological intervention. Its activities may provide insight into the complex relationship between human and ecosystem health.</p>","PeriodicalId":100392,"journal":{"name":"Ecosystem Health","volume":"3 1","pages":"11-26"},"PeriodicalIF":0.0,"publicationDate":"2008-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1526-0992.1997.00703.pp.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72600735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hypothesis is that old, weathered landscapes respond differently from young landscapes when subjected to intensive landuse. The major difference in response is that system function regresses or fails in old landscapes. The aging phenomenon is illustrated using data from a podzol chronosequence on coastal sand dunes at Cooloola, Queensland, Australia. The old systems here are shown to regress naturally from forest systems to health systems as access to nutrients decreases. Responses to landuse disturbances in old landscapes other than sand dunes, show analogous regressive trends to the dune landscapes, but the biophysical nature of the responses can vary. How can such trends in landscape health be measured to better link land capability with landuse? The concept of sustainability may not be appropriate for old landscapes and a different framework based on a health paradigm is suggested. Starting from an equilibrium perspective, we move to a conditional stability concept and then to a conditional health paradigm. Health and ill-health are deemed to be definable within predetermined limits, that is a compliance measure, similar to the diagnostic approach in human medicine.</p>\u0000 </div>","PeriodicalId":100392,"journal":{"name":"Ecosystem Health","volume":"7 1","pages":"7-14"},"PeriodicalIF":0.0,"publicationDate":"2003-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1046/j.1526-0992.2001.007001007.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83580111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paradox is relevant because it predicts that attempts to sustain a population by making its food supply more abundant (e.g., by nutrient enrichment) may actually have the reverse (paradoxical) effect of destabilizing the network. Originally, this paradox was based upon studies of “reasonable,” but quite simple, predator-prey models. Here, we attempt a more “realistic” revision of the paradox that explicitly accounts for the embedded nature of the human system in a complexly interwoven set of hierarchical (spatial, temporal, and organizational) relations with the rest of the ecosphere-a relationship whose exploitative nature continues to grow in intensity and extent. This revision is attempted with the aid of a combined thermodynamic and network approach. The result is that a scaledependent asymmetry in the action of the second law of thermodynamics is shown-an asymmetry that results in the creation of two antagonistic propensities: local order and local disorder. The point of balance between these two propensities is empirically measurable and represents a balance between processes and constraints internal (growth and development) and external (interactive and perturbing influences) to a system-a balance that may be called the most “adaptive” state (after Conrad 1983). The use of such an index of this balance is demonstrated and it is used to clarify the relevance of the paradox to more complexly organized systems. As a consequence, we conclude that the concept of “sustainable exploitation and growth” is an oxymoron.</p>","PeriodicalId":100392,"journal":{"name":"Ecosystem Health","volume":"7 3","pages":"163-178"},"PeriodicalIF":0.0,"publicationDate":"2003-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1046/j.1526-0992.2001.01024.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91891376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
