The potential of soil organic carbon sequestration for climate change mitigation and food security
نویسندگان
چکیده
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 organic soils. Realizing this potential could offset 6-16% of current greenhouse gas (GHG) emissions.

Carbon sequestration in sugarcane plant and soil with different cultivation systems
Sugarcane (Saccharum officinarum L.) is a multi-purpose crop, mainly planted in South-western (SW) parts of Iran. However, the capability of sugarcane farms to sequestrate carbon into soil and plant is not well documented. In this research, the carbon sequestration in sugarcane plant and soil in a ratooning traditional cultivation system at the Amirkabir Sugarcane Agro-Industry Complex...
متن کاملPotential of Carbon Sequestration of Hammada salicornica Vegetation Type in Desert Areas (Case Study: South Khorasan, Iran)
Climate change due to increasing the level of greenhouse gases including CO2 is the main environmental issue of the world in the new century. One of the effective way for reducing atmospheric CO2 is carbon sequestration by plants and soils. A vast area of Iran has desert condition with special adapted plant species in which can be devoted for carbon sequestration. Hammada salicornica as a shrub...
متن کاملManagement to mitigate and adapt to climate change
Management decisions both at the field and off-site have the potential to contribute to climate change mitigation and adaptation. Climate change threatens to increase the potential for soil erosion, reduce soil quality, lower agricultural productivity and negatively impact food security and global sustainability, making it one of the most severe challenges we will face in the 21st century. This...
متن کاملResponse to the discussion letter of Lassaletta and Aguilera "soil carbon sequestration is a climate stabilization wedge: comments on Sommer and Bossio (2014)".
Sommer and Bossio (2014) model the potential soil organic carbon (SOC) sequestration in agricultural soils (croplands and grasslands) during the next 87 years, concluding that this process cannot be considered as a climate stabilization wedge. We argue, however, that the amounts of SOC potentially sequestered in both scenarios (pessimistic and optimistic) fulfil the requirements for being consi...
متن کاملSoil carbon sequestration impacts on global climate change and food security.
The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the historic carbon loss of 42 to 78 gigatons of carbon. The rate of soil organic carbon sequestration with adoption of recommended technologies depends on soil texture and structure, rainfall, temperature, farming system, and soil management. Strategies to increase the soil carbon pool include soil restorat...
