Potential of global croplands and bioenergy crops for climate change mitigation through deployment for enhanced weathering.
Conventional row crop agriculture for both food and fuel is a source of carbon dioxide (CO2) and nitrous oxide (N2O) to the atmosphere, and intensifying production on agricultural land increases the potential for soil C loss and soil acidification due to fertilizer use. Enhanced weathering (EW) in agricultural soils-applying crushed silicate rock as a soil amendment-is a method for combating gl...
متن کاملClimate change mitigation: potential benefits and pitfalls of enhanced rock weathering in tropical agriculture.
Restricting future global temperature increase to 2°C or less requires the adoption of negative emissions technologies for carbon capture and storage. We review the potential for deployment of enhanced weathering (EW), via the application of crushed reactive silicate rocks (such as basalt), on over 680 million hectares of tropical agricultural and tree plantations to offset fossil fuel CO2 emis...
متن کاملThe potential of soil organic carbon sequestration for climate change mitigation and food security
SOC sequestration on cropland and grassland is an important mitigation option with potentially significant cobenefits for food security. At a carbon price of 20 $/tCO2eq, Paustian et al. (2016) identified a technical mitigation potential of 3-8 GtCO2eq/yr related to improved cropland and grassland management, biochar application, enhanced root phenotypes, and restoration of degraded lands and o...
متن کاملThe Role of Health Co-Benefits in the Development of Australian Climate Change Mitigation Policies
Reducing domestic carbon dioxide and other associated emissions can lead to short-term, localized health benefits. Quantifying and incorporating these health co-benefits into the development of national climate change mitigation policies may facilitate the adoption of stronger policies. There is, however, a dearth of research exploring the role of health co-benefits on the development of such p...
متن کاملClimate change and nutrition: creating a climate for nutrition security.
BACKGROUND Climate change further exacerbates the enormous existing burden of undernutrition. It affects food and nutrition security and undermines current efforts to reduce hunger and promote nutrition. Undernutrition in turn undermines climate resilience and the coping strategies of vulnerable populations. OBJECTIVES The objectives of this paper are to identify and undertake a cross-sectora...
