Greenhouse gases (GHGs) are vital components of the earth’s atmosphere, trapping heat around the earth, maintaining temperatures necessary for human existence. Until the Industrial Revolution, these gases existed in a natural equilibrium with the environment. Since that time, anthropogenic activities such as fossil fuel burning and land clearing have increased the quantity of GHGs, such as carb...

• In the short term, using price-driven instruments (through tax or trading) will allow flexibility in how, where and when emission reductions are made, providing opportunities and incentives to keep down the cost of mitigation. The price signal should reflect the marginal damage caused by emissions, and rise over time to reflect the increasing damages as the stock of GHGs grows. For efficiency...

We have used the CCSR/NIES/FRCGC atmospheric general circulation model (AGCM) based transport model for simulations of greenhouse gases (GHGs), e.g., CO2, N2O, SF6, and a transport diagnostic tracer Radon (half-life 3.8 days). These simulations are now being analyzed comparing with observations and preparing strategies for future inverse modeling of GHG fluxes. The JMA CDTM is used for tracer t...

This article provides an overview of the effects of land-use on the fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) and from peatlands in the Nordic countries based on the field data from about 100 studies. In addition, this review aims to identify the gaps in the present knowledge on the greenhouse gas (GHG) balances associated with the land-use of these northern ecosyste...

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...

Agriculture is a significant emitter of GHGs. Especially ruminant production systems that contribute substantially to global warming due to the enteric fermentation. Ruminant production systems are often integrated in mixed farm systems, including arable production, grassland systems and possibly energy production, which may provide opportunities for mitigation of GHGs when considered as a whol...

The expansion and intensification of agroecosystems worldwide has significantly affected the environment at multiple spatial scales (Matson et al., 1997). Agroecosystem effects on atmospheric constituents have altered local, regional, and global environmental quality through windblown soil (Zhang et al., 2001) and emission of particulate matter, reactive N (e.g., NH3 and NOx), volatile organic ...
