Again, whilst you are correct in saying that a few changes in fertilizer practices in the US, China and India could yield large
agricultural emissions benefits I would not bet on any wholesale (or even small and targeted) changes being made in those three countries any time soon.
Not exact matches
All these supports and promotion schemes for liquid biofuels should be scrapped, because of overwhelming scientific evidence that using land to produce energy crops delivers no climate
benefits at all once
agricultural emissions and land - use change are taken into account.
The authors of this new research paper analysed data and models from the USEPA's updated global non-CO2 GHG mitigation assessment to investigate the potential for GHG reductions from
agricultural emissions from seven regions globally, offsetting costs against social
benefit of GHG mitigation (e.g. human health, flood risk and energy costs).
In addition, the
benefits of avoided
emissions of air pollutants have been estimated for
agricultural production and the impact of acid precipitation on natural ecosystems.
This technical document provides a brief review of the
benefits from various agriculture - based practices and technologies that have the potential to increase food production and the adaptive capacity of the food production system, as well as reduce
emissions or enhance carbon storage in
agricultural soils and biomass, focusing in detail on empirical evidence concerning costs and barriers to adoption, both from household and project - level data.
This technical document presents the latest estimates of the
emissions gap in 2020 and provides plentiful information, including about current (2010) and projected (2020) levels of global greenhouse gas
emissions, both in the absence of additional policies and consistent with national pledge implementation; the implications of starting decided
emission reductions now or in the coming decades;
agricultural development policies that can help increase yields, reduce fertilizer usage and bring about other
benefits, while reducing
emissions of greenhouse gases; and, international cooperative initiatives that, while potentially overlapping with pledges, can complement them and help bridge the
emissions gap.
While such reductions would not replace the need to reduce CO2
emissions, they could have the result of lowering global temperature by 0.5 degrees Celsius (0.9 degree Fahrenheit) by mid-century, as well as having the added
benefits of saving lives and boosting
agricultural yields.
Likewise, all three could
benefit from payments to farmers in support of
emission - reducing
agricultural practices, but only the United States already has such a program (although repackaging agri - environment payments to farmers as a «climate mitigation activity» is proving a tough sale).
Jon Sanderman, a co-author with Griscom, as well as a soils experts at Massachusetts» Woods Hole Research Center, said skeptical farmers are coming to understand that natural techniques used to sequester soil carbon and reduce
agricultural emissions also end up
benefiting soil health, water retention and crop yields, thus promoting food security — a big worry in developing countries.
