AN ECONOMETRIC ANALYSIS OF THE CAUSES OF TROPICAL DEFORESTATION: GHANA AgEcon
Yiridoe, Emmanuel K.; Nanang, David M..
Deforestation is modeled in two stages, as an interaction of interlinked key sectors in the Ghanaian economy (including forest products exports, fuelwood energy consumption, cocoa production, and food crop production), which compete for forest landuse or forest products. The effects of the different first- and second-level causes of deforestation analyzed are discussed.
Tipo: Conference Paper or Presentation Palavras-chave: Two-stage regression; Elasticity of deforestation; Forest policy/management; Resource /Energy Economics and Policy; C320; Q230.

MARGINAL ABATEMENT COSTS OF REDUCING GROUNDWATER-N POLLUTION WITH INTENSIVE AND EXTENSIVE FARM MANAGEMENT CHOICES AgEcon
Yiridoe, Emmanuel K.; Weersink, Alfons.
Cost-effectiveness is an important consideration in evaluating choices for meeting environmental quality objectives. Estimated crop yield response functions and the associated groundwater-nitrate pollution production functions were used to evaluate the optimal N fertilization and on-farm abatement costs for alternative cropping systems, with management choices at both the intensive and extensive margins. The cost-effective corn production system, which meets the Health Canada standard for nitrates with the highest returns ($278 ha-1) and lowest on-farm abatement cost ($248 ha-1), was a four-year corn-corn-soybean-wheat rotation under conventional tillage. At contaminant limits above the Health Canada standard, the cost-effective wheat cropping system...

Mitigating the High Cost of ISO 14001 EMS Standard Certification: Lessons from Agribusiness Case Research AgEcon
Yiridoe, Emmanuel K.; Marett, Geb E..
Small and Medium Enterprises (SMEs) account for an estimated 90% of the world's economic activity, implying that environmental management strategies customized specifically for such organizations are important in a global environmental management initiative such as ISO 14001. The cost of third party ISO 14001 standard registration can be extremely high, and generally beyond the means of SMEs. Three dimensions to ISO 14001 EMS standard registration, which can substantially affect the cost associated with developing, implementing and obtaining ISO 14001 accreditation, were examined: i) whether the EMS implementation and registration process is direct or indirect; ii) how an organization can demonstrate compliance with ISO 14001 requirements; and iii)scale of...
