This paper examines the economics of catch discarding in fisheries. To study this issue a simple dynamic fisheries model is constructed. On the basis of this model it is demonstrated that in a differentiated fishery discarding of catch may be socially optimal. The paper goes on to show that...

This study was intended to develop an understanding of producer preference for land-based carbon sequestration in agriculture. We conducted a mail survey to elicit producer choice to provide marketable carbon offsets by participating in different carbon credit programs characterized by varying...

The recent/current recession provides the opportunity to study the effects of the macroeconomic changes on the agricultural production systems in the Great Plains and trace some of its impacts through the system to changes in primary inputs such water resource use. Therefore, the objective of...

The aim of this paper is to estimate the perennial crop potential regarding new uses like second generation biofuels. We focus on the introduction of a perennial yearly harvested crop, namely the miscanthus, in European agricultural short term supply model - AROPAj. Inserting this crop in the...

Both the goal of energy independence and the desire to lower greenhouse gas emission have triggered the search for alternate energy sources. For second generation biofuel production, a key question is which form of industrial organization should be adopted in order to stimulate stable feedstock...

This paper compares environmental and profitability outcomes for a centralized biorefinery for cellulosic ethanol that does all processing versus a biorefinery linked to a decentralized array of local depots that pretreat biomass into concentrated briquettes. The analysis uses a spatial...

In this workshop the participants identified five priority areas of concern relative to sustainable management of groundwater irrigation by farmers:1) aquifer drawdown; 2) FMIS groundwaterwater support services, 3) management problems under water-surplus conditions; 4) management problems under...

Using a bio-economic model, H2OBeef, that includes traditionally considered parameters associated with running a beef feedlot but also incorporates aspects associated with water, changes that can alter water consumption and or price are examined. The results indicate that when water does not...
