Quantifying greenhouse gas emissions from soils: Scientific basis and modeling approach
Global climate change is one of the most important issues of contemporary environmental safety. A scientific consensus is forming that the emissions of greenhouse gases, including carbon dioxide, nitrous oxide and methane, from anthropogenic activities may play a key role in elevating the global temperatures. Quantifying soil greenhouse gas emissions is an essential task for understanding the a...
متن کاملGreenhouse gas fluxes in southeastern U.S. coastal plain wetlands under contrasting land uses.
Whether through sea level rise or wetland restoration, agricultural soils in coastal areas will be inundated at increasing rates, renewing connections to sensitive surface waters and raising critical questions about environmental trade-offs. Wetland restoration is often implemented in agricultural catchments to improve water quality through nutrient removal. Yet flooding of soils can also incre...
متن کاملModelling of Greenhouse Gas Emissions from Wheat Production in Irrigated and Rain-Fed Systems in Khorasan Razavi Province, Iran
Agriculture has a key role in greenhouse gas emissions. As such, the present study aimed to evaluate the greenhouse gas emissions from wheat production in irrigated and rain-fed systems. The primary data were collected from 116 wheat farmers. The results showed that the total greenhouse gas emissions from wheat production in irrigated and rain-fed systems were 637.8 and 65.12 kgCO2eq, respecti...
متن کاملThe effects of biochar on wetland and agricultural soil carbon and nitrogen emissions in North Carolina
Executive Summary Biochar is an increasingly popular topic in environmental management due to its potential effects on several ecosystem functions. Specifically, biochar has been linked to significant reductions in greenhouse gas emissions, including nitrous oxide, carbon dioxide and methane when used as a soil amendment. It has also been suggested as a long term mechanism to sequester carbon i...
متن کاملA Worldwide Assessment of Greenhouse Gas Emissions from Drained Organic Soils
Despite the importance of organic soils, including peatlands, in the global carbon cycle, detailed information on regional and global emissions is scarce. This is due to the difficulty to map, measure, and assess the complex dynamics of land, soil, and water interactions needed to assess the human-driven degradation of organic soils. We produced a new methodology for the comprehensive assessmen...
