Potential soil carbon sequestration in a semiarid Mediterranean agroecosystem under climate change: Quantifying management and climate effects

Potential soil carbon sequestration in a semiarid Mediterranean

Soil carbon sequestration to mitigate climate change

The increase in atmospheric concentration of CO2 by 31% since 1750 from fossil fuel combustion and land use change necessitates identification of strategies for mitigating the threat of the attendant global warming. Since the industrial revolution, global emissions of carbon (C) are estimated at 270F 30 Pg (Pg = petagram= 10 g = 1 billion ton) due to fossil fuel combustion and 136F 55 Pg due to...

The 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...

Climate change Effects of Surface soil temperature profile in Ahwaz

In arid and semi-arid regions, soil surface warming is a considerable phenomenon causing a high thermal gradient which makes water flow intensely. The degree of soil temperature is effective on crop production, plant growth and soil microorganisms. In recent years, the ascending trend of temperature has been substantially noticed by researchers in the issues of pointwise climate change and at w...

Soil 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...
