Perennial crops reduce the need for tillage and thus help mitigate soil erosion, and may help increase soil organic matter. Globally, soils are estimated to contain >8,580 gigatons of organic carbon, about ten times the amount in the atmosphere and much more than in vegetation.
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO 2) from ...
Deforestation is a primary contributor to climate change, [ 1 ][ 2 ] and climate change affects the health of forests. [ 3 ] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [ 4 ][ 5 ] Greenhouse gases are emitted from ...
Soil carbon is the solid carbon stored in global soils. This includes both soil organic matter and inorganic carbon as carbonate minerals. It is vital to the soil capacity in our ecosystem. Soil carbon is a carbon sink in regard to the global carbon cycle, playing a role in biogeochemistry, climate change mitigation, and constructing global ...
Climate stabilization wedges are used to describe possible climate change mitigation scenarios and their impact, through the grouping of different types of interventions into "wedges" representing potential decreases in CO 2 emissions. When stacked on top of each other, wedges form a "stabilization triangle" that represents the estimated amount ...
The erosion could reduce the ocean's ability to absorb more than 14 million tons of CO2 per year by century's end, the researchers found. ( A typical passenger car emits about 5 tons of CO2 per year.)
Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades. This may sound like a small uptick, but the implications are profound. Rising temperatures will destroy plant and animal habitats ...
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
