Since 1990, total cropland has declined by 31 million acres, or 7%. during 2018 totaled 400 million acres and represented 17% of U.S. Cropland includes land area used to produce traditional row crops, perennial crops, horticultural crops, pastureland or hay land, fallow land and Conservation Reserve Program lands. land area it has declined by 2.7 million acres, or 0.4%, since 1990.įollowing forestland, the third-largest land use category in the U.S. ![]() during 2018 totaled 716 million acres, representing 31% of U.S. Forestland does not include land that is predominantly used for farming or land that is completely surrounded by urban or developed areas. In addition, forestland includes unimproved roads, trails, streams and clearings in forest areas, as long as they meet certain size criteria. Land in transition zones, i.e., areas between forestland and non-forestland, such as urban zones, that have at least 10% tree cover are also categorized as forestland. Forestland represents land area that is at least 1 acre in size with at least 10% cover by live trees and includes land that has tree cover that will be naturally or artificially regenerated. The second-largest land use category is forestland. area, and has increased by 2.7 million acres, or 0.3%, since 1990. during 2018 totaled 898 million acres, or 39% of total U.S. Grassland vegetation practices that may result in CO2 emissions include clearing, burning, chaining or chemical application. Savannas, deserts and tundra are also considered grassland. Grassland is the largest land use category and is composed principally of grasses, sedges, rushes, forbs or shrubs suitable for grazing and browsing, woody plants, drained wetlands, pasture, rangeland and land with three or fewer years of continuous hay production. ![]() There are five primary land use categories for measuring both carbon emissions and carbon sinks related to land use, land-use changes and forestry. Today’s article reviews trends in carbon offsets achieved through forestry, grassland, cropland and wetland management. Since 1990, the ability to reduce carbon stocks through land and forestry management practices has decreased by approximately 9%, or 80 million metric tons of CO2 equivalent. CO2 removals in 2018 represented 12% of the total GHG emissions and resulted in reducing net GHG emissions to 5.7 billion metric tons. A variety of carbon-capturing practices are used on agricultural lands, including but not limited to conservation cover crops, no-till or reduced tillage, anaerobic digesters and nutrient management, e.g., GHG and Carbon Sequestration Ranking Tool.ĮPA data reveals that during 2018 carbon sequestration efforts resulted in an increase in CO2 stocks, i.e., carbon removed from the atmosphere, of 764 million metric tons. To offset GHG emissions and reduce atmospheric CO2, carbon can be trapped in soils through various carbon sink activities such as the growth of trees, forestry management that reduces forest fires and forest degradation, increasing below-ground plant matter and sequestering carbon in soils through cropland, wetland or grassland management. ![]() GHG emissions have increased by 4%, or 240 million metric tons. ![]() greenhouse gas emissions in 2018 totaled 6.7 billion metric tons in CO2 equivalents, up 2%, or 188 million metric tons, from the prior year ( Agriculture’s Greenhouse Gas Emissions and Sinks). The most recent data from the Environmental Protection Agency’s Greenhouse Gas Inventory Data Explorer reveals U.S.
