Sustainability is a relationship, or balancing act, between many factors (social, environmental and economic realities and constraints) that are constantly changing (Munasinghe & McNeely, 1995; Pirages, 1994). Ensuring sustainability over time means maintaining a dynamic balance among a growing human population and its demands, the changing capabilities of the physical environment to absorb the...

Although ecosystems provide myriad services to economies, only one service is considered in most renewable-resource models. The general equilibrium bioeconomic model introduced here admits a second service, and more importantly it accounts for how the two services are impacted by interactions within an eight-species ecosystem and interactions within a regional economy. Endangered Steller sea li...

A modeler must often rely on highly simplified representations of complex physical systems when analyzing associated economic issues. Herein, we consider a management problem in which a bioeconomic system exhibits simultaneity in processes governing productivity and damage. In this case, it may benefit the producer to sacrifice productivity to reduce the costs associated with increased damage. ...

The arrival of novel pathogens and pests can have a devastating effect on the market values of forests. Calibrating management strategies/decisions to consider the effect of disease may help to reduce disease impacts on forests. Here, we use a novel generalisable, bioeconomic model framework, which combines an epidemiological compartmental model with a Faustmann optimal rotation length model, t...

Wastewater reuse for aquaculture is a reality in several Asian countries, however, traditional practices face constraints including inadequate or contaminated wastewater inputs and growing concern over health risks. Based on Kolkata and a wastewater flow of 550,000m(3)d(-1), rational and conventional designs for lagoon-based wastewater treatment and reuse through aquaculture were compared using...

Bioeconomy is one of the leading science directions at present time; countries and international organizations around world pay close attention to it. They are actively working on policies strategies for transition a bioeconomy. based advances in microbiology that can be used various processes associated with use biological resources; it changing consumer preferences by bringing new understandi...

Sow production indicators, including litter size, litter weight, and the length of time that sows remained in the herd (sow longevity), were used to characterize sow performance and profitability. Sow longevity and production records from 148,568 sows in 32 commercial herds from Central Illinois from January 1995 to May 2001 were analyzed using survival and repeatability models, respectively. T...

Strong sustainability has not been truly operationalized despite the fact that it is one of major challenges facing society today. Thus, this work proposes a way to rediscover bioeconomic epistemology Nicholas Georgescu-Roegen as an approach toward informing strong operationalizations. Through literature review, article demonstrates how various studies (stock-flow or fund-flow models, multi-sca...
