Cattle farming is a major source of greenhouse gases (GHGs). Recent research suggests that GHG fluxes from dung pats could be affected by biotic interactions involving dung beetles. Whether and how these effects vary among beetle species and with assemblage composition is yet to be established. To examine the link between GHGs and different dung beetle species assemblages, we used a closed cham...

Pastures are important environments worldwide because they offer many ecosystem services and sustain meat milk production. However, pastures ecosystems responsible for greenhouse gas (GHG) emission. The major GHGs include CO2, CH4, N2O. present review summarizes GHG emission from pasture discusses strategies to mitigate this problem. In pastures, emissions originate animal excretion, fertilizat...

Scientific assessments of agricultural air quality, including estimates of emissions and potential sequestration of greenhouse gases, are an important emerging area of environmental science that offers significant challenges to policy and regulatory authorities. Improvements are needed in measurements, modeling, emission controls, and farm operation management. Controlling emissions of gases an...

Plug-in hybrid electric vehicles (PHEVs), which use electricity from the grid to power a portion of travel, could play a role in reducing greenhouse gas (GHG) emissions from the transport sector. However, meaningful GHG emissions reductions with PHEVs are conditional on low-carbon electricity sources. We assess life cycle GHG emissions from PHEVs and find that they reduce GHG emissions by 32% c...

Loss of nitrate from agricultural lands to surface waters is an important issue, especially in areas that are extensively tile drained. To reduce these losses, a wide range of in-field and edge-of-field practices have been proposed, including constructed wetlands. We re-evaluated constructed wetlands established in 1994 that were previously studied for their effectiveness in removing nitrate fr...

Greenhouse gas (GHG) emissions resulting from the Land Use, Land-Use Change, and Forestry sector (LULUCF) are estimated and reported in National Communications to the United Nations Framework Convention on Climate Change (UNFCCC). By definition, the LULUCF sector is a “greenhouse gas (GHG) inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induce...

Accurate estimation of emissions greenhouse gases (GHGs) is required for making effective climate change mitigation policies at the national level. Among major sources, municipal solid waste (MSW) an important source GHGs, such as methane (CH4), generated during anaerobic decomposition organic matter. In Viet Nam, GHGs are not well quantified, in particular from MSW management system. this stud...

The use of fossil fuels is increasingly questioned due to depleting natural energy assets and the buildup of greenhouse gases (GHGs). Biofuels are an efficient substitute to existing fossil fuel based energy sources as they can be utilized for transport with little modification to existing techniques. They thus offer the prospect of ecological sustainability and reduced GHGs emission. Microalga...

The United Nations, Food and Agricultural Organization [FAO, Steinfeld, Gerber, Wassenaar, Castel, Rosales, and de Haan (2006). Livestock’s Long Shadow. Food and Agriculture Organization of the United Nations] report titled Livestock’s Long Shadow (LLS) stated that 18% (approximately 7100 Tg CO2eq yr ) of anthropogenic greenhouse gases (GHGs) are directly and indirectly related to the world’s l...

Reducing and off-setting anthropogenic emissions of CO(2) and other greenhouse gases (GHGs) are important strategies of mitigating the greenhouse effect. Thus, the need for developing carbon (C) neutral and renewable sources of energy is more than ever before. Use of crop residue as a possible source of feedstock for bioenergy production must be critically and objectively assessed because of it...
