Dear C-AGG Participants and Stakeholders – FAO and France urge including agriculture in global climate change debate MORE TARGETED POLICIES AND INVESTMENTS NEEDED TO ADAPT AGRICULTURE TO THE IMPACTS OF CLIMATE CHANGE FAo Director-General José Graziano da Silva...
Impending risks associated with climate change have forced the global community to devise tradable pollution permit or “cap and trade” approaches to control the release of greenhouse gases. In the U.S, soils have the potential to offset about 10 percent of annual CO2...
The CENTURY version 5 agroecosystem model is the latest version of the soil organic model developed by Parton et al. (1987). This model simulates C, N, P, and S dynamics through an annual cycle over time scales of centuries and millennia. The producer submodel may be...
Abstract Mathematical modelling has widely been used during the last 20 years to estimate and predict soil organic carbon (SOC) balance and nutrients dynamic on the landscape scale. The model simulations are applied and developed to assess the long-term effects of...
U.S. ENERGY-RELATED CARBON DIOXIDE EMISSIONS INCREASED 2.5% IN 2013 Energy-related carbon dioxide emissions (CO2) increased from 5,267 million metric tons (MMmt) in 2012 to 5,396 MMmt in 2013 (2.5%). The 2013 increase was largely the result of colder weather leading...
The Salt Lake Valley, long recognized for its spectacular mountain views and abundant outdoor activities, has in recent years earned a negative reputation for its air quality problems. During winter months, the valleys of Northern Utah consistently rank among the...
Overview The Global Warming Solutions Act of 2006 (AB 32) requires that the California Air Resources Board (ARB) determine the statewide 1990 greenhouse gas (GHG) emission level and approve a statewide greenhouse gas emissions limit, equal to the 1990 level, to be...
Air Quality Trends EPA creates air quality trends using measurements from monitors located across the country. The table below show that air quality based on concentrations of the common pollutants has improved nationally since 1980. (See the trends graphs...
The US Composting Council is firmly opposed to landfilling yard debris and other source-separated organics when viable alternatives are available. It is an inefficient way to use our organic feedstocks–wasting resources, reducing recycling, and potentially...
