UN Conference on Desertification Opens in Mongolia, Linking Land Degradation to Global Migration and Conflict

With 77 percent of its own territory already degraded into arid steppe and desert, Mongolia opened the 17th United Nations Conference on Desertification (COP17) in Ulaanbaatar on Monday. Approximately 10,000 delegates, including government negotiators, scientists, and representatives of pastoral communities, convened to negotiate a global response to the rapid deterioration of the Earth's soil. The two-week summit, operating under the theme 'Restoring Land, Restoring Hope,' marks the first time the UN's primary land-focused conference has been held in East or Central Asia.[1][2][3]

The Convention to Combat Desertification (UNCCD) is one of the three 'Rio Conventions' established in 1992, alongside the more prominent climate change and biodiversity treaties. Historically, the desertification framework has garnered the least international attention. However, recent severe heatwaves, wildfires, and prolonged droughts across the Northern Hemisphere have elevated the urgency of the Ulaanbaatar talks, positioning land management as a critical component of global climate resilience.[3][4]

The stakes are structural and immediate. According to United Nations estimates, up to 40 percent of the world's land is currently degraded, a condition that undermines food production and water availability for nearly half of humanity. When agricultural productivity collapses, the resulting economic and social vulnerability frequently translates into forced displacement. Negotiators at COP17 are explicitly linking land degradation to global migration and regional instability, framing soil restoration as a matter of national security.[4]

A central friction point at the summit is the massive financial shortfall required to halt the crisis. The conference aims to operationalize pledges made two years ago, which involve allocating roughly $12 billion to vulnerable nations to help them manage drought and land degradation. Yet environmental economists note that this figure is a fraction of the estimated $2.6 trillion needed by 2030 to repair degraded land, restore soils, and build adequate drought defenses globally.[3]

The pressure is particularly acute for rural and nomadic populations. Rangelands—encompassing grasslands, savannas, and shrublands used for grazing—cover more than half of the Earth's land surface and support approximately 2 billion people. Recognizing this, the UN declared 2026 the International Year of Rangelands and Pastoralists, an initiative championed by the Mongolian government to ensure that the livelihoods of herders are integrated into the new strategic framework.[1][2]

Mongolia's domestic policies are serving as a backdrop for the negotiations. The host nation has committed to spending at least 1 percent of its gross domestic product annually on fighting climate change and desertification. Its 'Billion Trees' campaign, launched in 2021, aims to restore vast tracts of land by 2030, offering a template for integrating land restoration with rural economic development.[1][2]

Disaster risk reduction agencies are using the summit to push for a pivot from reactive crisis management to proactive prevention. By investing in early warning systems and integrating land protection into broader development planning, agencies argue that governments can mitigate the worst impacts of drought before they trigger mass migration or famine.[5]

Negotiations will continue behind closed doors through the first week, focusing on drought resilience, finance, and the protection of pastoralist communities. A high-level segment featuring senior government ministers will commence on August 24 to finalize the UNCCD's post-2030 strategic framework, which will dictate the trajectory of global land management investments for the remainder of the decade.[3][4]
