Sensitivity of Global Pasturelands to Climate Variation
网页2019年11月14日 · Pasturelands are globally extensive, sensitive to climate, and support livestock production systems that provide an essential source of food in many parts of the world. In this paper, we integrate information from remote sensing, global climate, and land use databases to improve understanding of the resilience and resistance of this ...
Pasture - Wikipedia
网页Pasture (from the Latin pastus, past participle of pascere, "to feed") is land used for grazing. [1] Types of pasture. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine.

网页Pasture. Pasturelands cover 121.1 million acres (6% of the U.S. surface area), predominantly in the eastern half of the U.S. While mostly used for livestock grazing and hay production, pastures also offer other ecosystem services, enhance environmental quality and provide scenic landscapes.
Greenhouse gas balance in global pasturelands and rangelands
网页2020年9月17日 · In pasturelands and rangelands, net GHG balance was dominated by an increasing contribution from N 2 O and CH 4 fluxes, respectively. Our results also indicate large spatial and regional variations in GHG balance, with Europe acting as a small GHG source and other regions (i.e. Africa and Southern Asia) a strong GHG sink.

Satellites Find Greener Pastures - NASA Earth Observatory
网页2019年3月12日 · Degraded pastures tend to have bare soil, more invasive species, and less nutrients to support livestock. They also retain less carbon in the soil and contribute more to greenhouse gas emissions. Ferreira’s team found that the northeastern and center-west portions of the country showed the most land degradation.
Global pastureland use as reflected in inter-regional supply chain
网页2022年11月15日 · Pasturelands as the largest land biome on earth are undergoing significant change, and are reallocated to economic hot zones through the livestock supply chains. We highlight the fact that the global shift of pastureland resources from nature-based to economic-based cartography may exacerbate ecological inequity between world regions.
