This paper addresses the impacts of environmental legislation and vehicle emissions on the future of alternative fuels sucl~ as methanol, compressed natural gas, propane, electricity, hydrogen, and reformulated gasoline in the transportation industry, and it discusses the advantages and disadvantages of each type of fuel in terms of fuel efficiency, fuel cost, environmental impacts, and vehicle...
Farmers' perception of the environmental impacts of modern agricultural technology diffusion and factors determining such awareness were examined using survey data from 21 villages in three agro-ecological regions of Bangladesh. Results reveal that farmers are well aware of the adverse environmental impacts of modern agricultural technology, although their awareness remains confined within visi...
The possibility of using bioenergy as a climate change mitigation measure has sparked a discussion of whether and how bioenergy production contributes to sustainable development. We undertook a systematic review of the scientific literature to illuminate this relationship and found a limited scientific basis for policymaking. Our results indicate that knowledge on the sustainable development im...
Assessing the impacts of chemical mixtures in the environment is challenging largely because of high variation: diverse sources and constituents; routes of environmental exposure; taxa-specific sensitivities. This complexity and uncertainty leads to concerns that current prospective risk assessment (RA) methods are insufficient for appropriate environmental protection. Likewise, there is scope ...
Organic farming practices have been promoted as, inter alia, reducing the environmental impacts of agriculture. This meta-analysis systematically analyses published studies that compare environmental impacts of organic and conventional farming in Europe. The results show that organic farming practices generally have positive impacts on the environment per unit of area, but not necessarily per p...
