  • Rangelands cover over 50% of the world’s terrestrial area. They also support an estimated 500 million pastoralists who play a crucial role in livestock production and allied occupations. About half of the world’s rangelands are degraded and need policy interventions, and communities depending on them need focused support, according to a new report of the United Nations Convention on Combating Desertification (UNCCD). The UNCCD report defines rangelands as natural or semi-natural ecosystems that are grazed by livestock or wild animals. Rangelands contain vegetation such as grasses, shrubs, bushes, open forests, and agroforestry systems (land which contains trees and crops or pastures). The exact nature of rangelands’ vegetation is influenced by rainfall, temperature, and other climate phenomena, according to the Rangeland Atlas, prepared by a consortium of international non-profits and United Nations agencies. Currently, rangelands cover 80 million sq km of Earth’s terrestrial surface area (over half of Earth’s land) and are thus the largest land cover or land use type in the world, the UNCCD report said. They act as carbon sinks (which absorb more carbon from the atmosphere than they release), storehouses of freshwater, and prevent desertification of land. Millions of people worldwide depend on rangelands for food security, and livelihoods.
    What are rangelands? Why are they important? What does the UNCCD report find, we discussed in this video.
