Increased CO2 release from soils resulting from agricultural practices such as tillage has generated concerns about contributions to global warming. Maintaining current levels of soil C and/or sequestering additional C in soils are important mechanisms to reduce CO2 in the atmosphere through production agriculture. We conducted a study in northern Alabama from 2003 to 2006 to measure CO2 efflux...

We monitored soil respiration (Rs), soil temperature (T) and volumetric water content (VWC%) over four years in one typical conventional and four alternative cropping systems to understand Rs in different cropping systems with their respective management practices and environmental conditions. The control was conventional double-cropping system (winter wheat and summer maize in one year--Con.W/...

The mangrove forest ecosystem is known to possess a variety of ecosystem services, including high rates of carbon sequestration, storage and mitigating climate change through reduced deforestation. This study was carried out in the mangrove forests of Gowatr Bay, Gulf of Oman during 2017-18 to quantify biomass and carbon stocks of all components of this forest, including live and dead trees, so...

By analyzing the decisions of policy makers and in addition public referenda, shadow prices for global warming (ca. 5 to 22 € per ton of CO2) and exceedance of critical loads for eutrophication and acidification (ca. 100 € per hectare of exceeded area and year with a range of 60 – 350 €/ha year) have been developed. These data are complementary to the valuation steps in ExternE, and can be used...

To clarify the link between existing infrastructure legacy and the 2°C target, we extend the work of Davis et al. (2010) by introducing non-CO2 greenhouse gases and the inertia in transportation-needs drivers. We conclude that climate policies able to maintain climate change below 2°C cannot disregard existing infrastructure. ha ls hs -0 07 24 49 3, v er si on 1 21 A ug 2 01 2 Author manuscript...
