The growing awareness on the multiple environmental impacts of livestock production has risen the necessity to widen the definition of efficiency to a multidimensional eco-efficiency concept. Our paper suggests a combined approach of a whole-farm agronomic model and frontier efficiency method to explore deeply the determinants of eco-efficiency. The whole-farm model used, GAMEDE, is randomly pa...

Eco-labeling signals that a product has been eco-certified. While there is increasing use of eco-labeling practices, there is still little understanding of the conditions under which eco-labels can command price premiums. In this paper, we argue that the certification of environmental practices by a third party should be analyzed as a strategy distinct from although related to the advertisement...

For a cropping system to be sustainable, should not only the soil nitrogen (N) content be preserved but also the N runoff be minimised. Finding a simple but robust way to estimate N runoff would thus be a great advantage when evaluating cropping systems. In this study all major N flows in six different cropping systems, each covering 0.18 ha of a separately pipe drained field lysimeter, located...

The value of water resources and bodies has been acknowledged in terms of environmental, ecological, and landscape vision and sight because water itself is closely interrelated to the existence and expansion of humanity. The eco-design and eco-innovation of rural-housing in reservoir environment with sustainable tourism and mass-tourism development are under rising pressure of prohibited housin...

Pollution occurs when the concentration of various chemical or biological constituents exceed a level implying negative impact on amenities, the eco-system, resources and human health. Oil spills are the serious environmental   hazards which often exhibit long-term impacts. The main objective of response to an oil spill is to reduce its impact on nature and human health. This paper allows us to...

At present, overseas and domestic eco-security early warning research is in the exploratory stage. This paper uses Kizilsu Kirghiz Autonomous Prefecture as the research object and constructs an evaluation index system based on the pressure-state-response (P-S-R) conceptual model. This study analyzes eco-security early warning in the study area using the granger causality test model, the entropy...
