On the Poverty of Our Nomenclature

This paper examines the recent proposal to christen our geological epoch “the Anthropocene.” The reasoning offered for this new name is that humanity’s enormous mark on the geological strata would be a discernible boundary to future geologists; therefore a change in nomenclature is called for to reflect our transition out of the Holocene (our epoch’s current formal name). I argue, however, that the pitch for the Anthropocene goes well beyond this rationale. The Anthropocene has morphed into a discourse that is organizing the perception of a world picture (past, present, and future) through a set of ideas and prescriptions that is tenaciously anthropocentric; indeed, the championed name itself—Anthropocene, or the age of Man—evokes the human-centeredness that is at the root of our ecological predicament. The main argument of this paper is that the discourse of the Anthropocene refuses to challenge human dominion, proposing instead technological and managerial approaches that would make human dominion sustainable. By the same token, the Anthropocene discourse blocks from consideration the possibility of abolishing a way of life founded on the domination of nature. In conclusion, I submit that while technological and managerial approaches have a place in addressing ecological problems, our predicament primarily calls for a drastic pulling back and scaling down of the human presence—welcoming limitations of our numbers, economies, forms of habitation, and uses of land and sea, so that humanity may flourish together with the entire breadth of Life

Diagnostic model for assessing traceability system performance in fish processing plants

This paper introduces a diagnostic tool that can be used by fish processing companies to evaluate their own traceability systems in a systematic manner. The paper begins with discussions on the rationale of traceability systems in food manufacturing companies, followed by a detailed analysis of the most important indicators in the designing and executing traceability systems. The diagnostic tool is presented in four grids through which fish companies can evaluate their own developed traceability system. The paper argues that if a company operates at a higher level of contextual factors, then design and execution of traceability system needs to be at a higher level as well so as to achieve a higher level of traceability system performance. The paper concludes that companies that are able to systematically assess their own developed traceability systems are able to determine food safety problems well in advance, and thereby take appropriate corrective actions

Inventory control for a perishable product with non-stationary demand and service level constraints

Abstract We study the practical production planning problem of a food producer facing a non-stationary erratic demand for a perishable product with a fixed life time. In meeting the uncertain demand, the food producer uses a FIFO issuing policy. The food producer aims at meeting a certain service level at lowest cost. Every production run a set-up cost is incurred. Moreover, the producer has to deal with unit production cost, unit holding cost and unit cost of waste. The production plan for a finite time horizon specifies in which periods to produce and how much. We formulate this single item -single echelon production planning problem as a stochastic programming model with a chance constraint. We show that an approximate solution can be provided by a MILP model. The generated plan simultaneously specifies the periods to produce and the corresponding order-up-to levels. The order-up-to level for each period is corrected for the expected waste by explicitly considering for every period the expected agedistribution of the products in stock. The model assumes zero lead time and backlogging of shortages. The viability of the approach is illustrated by numerical experiments. Simulation shows that in 95.8% of the periods the service level requirements are met with an error tolerance of 1%

Bottlenecks and Opportunities for Quality Improvement in Fresh Pineapple Supply Chains in Benin

This study mapped and diagnosed the fresh pineapple supply chains in Benin to identify bottlenecks in pineapple quality improvement for different markets. A research framework was defined that comprised all relevant aspects to be researched. After 54 semi-structured interviews with key informants, 173 structured interviews were held with actor groups. The chain diagnosis showed there was no concordance between actor groups in which quality attribute they valued most. Moreover, pineapple quality was found to be highly heterogeneous. Key bottlenecks identified were lack of training of primary producers in production practices, unconditioned transport, and unavailability of boxes for export
