Rangelands cover more than half of Earth’s land surface and are essential for sustaining billions of people worldwide. These diverse ecosystems, ranging from deserts to tundra, provide a wide variety of vital resources such as meat, dairy, fiber, and other staple foods. Additionally, rangelands play a crucial role in Earth’s nutrient, water, and carbon cycles, highlighting their significance in maintaining global environmental balance.
Recent findings from a report by the United Nations reveal that up to 50 percent of rangelands are currently degraded. This degradation is attributed to a range of factors, with poor land management practices playing a significant role. Activities such as land clearing, mining, overgrazing, and erosion contribute to soil nutrient depletion, salinization, and alkalinization, ultimately leading to drought and desertification. The widespread impact of these issues underscores the urgent need for intervention to prevent further deterioration of rangeland ecosystems.
In various regions across the globe, conflicts, border disputes, and overgrazing exacerbate rangeland degradation. For example, in Central Asia and Mongolia, one-third of the population relies on herding livestock, with rangelands comprising 60 percent of the land. The disruption of traditional practices and the increase in wildfires further threaten the health of these vital ecosystems. Similarly, in North America, ancient grasslands, prairies, and southern deserts are experiencing a decline in biodiversity due to ongoing degradation.
Efforts to address rangeland degradation must prioritize sustainable land management practices and conservation strategies. The incorporation of indigenous knowledge, along with local and scientific expertise, is crucial for designing effective management plans. Additionally, shifting away from damaging practices such as monocultural farming is essential for mitigating the negative impacts on rangeland health. Climate mitigation and cross-border cooperation are identified as key measures to prevent further degradation and protect the invaluable cultural, environmental, and economic values associated with rangeland ecosystems.
The global crisis of rangeland degradation requires immediate attention and concerted action from governments, organizations, and communities worldwide. By recognizing the importance of preserving and restoring these critical ecosystems, we can work towards a sustainable future where rangelands continue to support livelihoods, biodiversity, and ecological balance. Collaborative efforts to implement effective management practices and conservation initiatives are essential to safeguarding the health and productivity of rangelands for generations to come.
