As UNCCD COP17 closes in Mongolia, governments are giving greater weight to the economic consequences of land degradation and drought. New financing mechanisms, large-scale restoration models and a major rangelands initiative point toward a stronger implementation agenda, but global drought governance remains unresolved.
ULAANBAATAR — UNCCD COP17 is ending with a clearer policy signal than diplomatic breakthrough.
Governments have spent the summit pushing land degradation and drought further into discussions on food security, water, investment and economic resilience, while advancing new financing mechanisms and highlighting restoration models already operating at scale.
The stakes are considerable. Around 40 percent of the world’s land is affected by degradation and drought, threatening the livelihoods of more than three billion people, according to UNCCD. The international system has set a goal of restoring one billion hectares of degraded land by 2030.
The Land Degradation Financing Gap
UNCCD estimates roughly $355 billion a year will be needed through 2030 to address land degradation, desertification and drought. Current annual investment is about $77 billion, leaving a gap of approximately $278 billion.
The Convention estimates the required investment could generate around $1.8 trillion in annual benefits.
That financing gap has pushed implementation closer to the center of COP17.
Discussions have focused on blended finance, guarantees, development-bank participation and stronger project pipelines capable of attracting private capital, which still represents only a small share of restoration financing.
One concrete development is the Drought Resilience Investment Facility, launched during COP17 to use public and concessional capital to mobilize larger pools of private investment.
Its significance will depend on execution: whether it can generate viable projects, attract capital and deliver measurable resilience outcomes.
Restoration Is Beginning to Show What Scale Can Look Like
COP17 has also provided evidence that large-scale restoration is possible.
Three initiatives in Brazil, Saudi Arabia and the Sahel were recognized as UN World Restoration Flagships during the summit. Together, they aim to restore almost five million hectares by 2030.
The models are notably different.
Brazil’s Cerrado initiative brings together more than 180 partners and aims to restore two million hectares of one of the world’s most biodiverse savannahs by 2030. Saudi Arabia’s National Greening Program has already brought roughly one million hectares under restoration and planted 159 million trees, while targeting 2.5 million hectares restored by 2030.
Across Burkina Faso, Chad, Mali, Mauritania and Niger, a World Food Programme-led initiative has rehabilitated more than 335,000 hectares while supporting food security and livelihoods for over four million people. Monitoring cited by the UN found improved soil and vegetation conditions across 75 percent of restoration sites and an approximately 11 percent decline in households requiring humanitarian assistance during the lean season in participating areas.
For governments, these examples strengthen the case that restoration can be linked not only to environmental outcomes, but also to agricultural productivity, employment and resilience.
They also underscore COP17’s central implementation challenge: how to replicate successful models at the scale required globally.
Delivery Is Now the Credibility Test
COP17 also inherits unfinished implementation from Riyadh.
More than $12 billion in drought-resilience commitments were announced around COP16, including through the Riyadh Global Drought Resilience Partnership.
The challenge is now translating those commitments into projects such as drought-resistant agriculture, irrigation, water storage and broader resilience infrastructure.
For developing countries, the constraint is increasingly not simply access to pledges, but the ability to turn national priorities into financeable projects.
That places greater pressure on governments, development banks and donors to close the gap between political commitments and capital deployment.
Rangelands Move Up the Diplomatic Agenda
COP17 has also raised the profile of rangelands.
They cover more than half of the planet’s land surface, support roughly 500 million pastoralists and generate ecosystem benefits estimated at $21 trillion to $47 trillion annually, according to UNCCD research launched at the summit.
The new Rangelands Flagship Initiative connects restoration, pastoral livelihoods, biodiversity, food security and investment.
For governments across Africa, Central Asia, Latin America and the Middle East, that creates a potentially significant policy platform. The test will be whether ecological value can be translated into credible financing models and tangible benefits for pastoral and local communities.
The Unresolved Diplomatic Question: Drought
The most consequential negotiating issue remains drought governance.
COP16 failed to produce agreement on the future structure of international drought cooperation, leaving COP17 to address whether governments should pursue a stronger international instrument or a more voluntary framework.
That divide remains unresolved as COP17 moves through its closing process.
The issue increasingly extends across government portfolios. Drought can simultaneously affect agriculture, electricity generation, transport, public finances and migration.
This summer’s severe European drought has provided another reminder of that exposure, disrupting agriculture, power production and transport along major waterways including the Rhine and Danube.
A failure to resolve drought governance at COP17 would therefore leave a central diplomatic issue open. Even without a binding agreement, however, drought is gaining a more prominent institutional position within the UNCCD process.
Why It Matters for Governments
COP17 is reinforcing three shifts.
First, land degradation is increasingly being treated as an economic and resilience risk, rather than solely an environmental one.
Second, the debate is moving from commitments toward delivery. The restoration programs highlighted in Mongolia show that implementation at meaningful scale is possible, while the financing gap demonstrates how far the world remains from global targets.
Third, land policy is becoming more closely connected to food, water and public finance, potentially bringing restoration into areas of government policy with much larger budgets and economic consequences.
None of those shifts guarantees success.
The financing gap remains enormous, private investment remains limited and governments remain divided over the future of drought cooperation.
The Diplomatic Signal
COP17 is unlikely to be defined by a single sweeping agreement.
Its more significant legacy may be a clearer transition from why land restoration matters to how governments can deliver it.
The examples highlighted in Mongolia show that restoration can produce measurable environmental, livelihood and food-security gains. The financing discussions suggest governments are searching for mechanisms capable of taking those models to greater scale.
The unresolved drought negotiations demonstrate the limits of that progress.
For governments, the immediate question is what Parties ultimately agree in Ulaanbaatar. The larger question is whether COP17 can turn proven restoration models and political commitments into investment and implementation at the scale the land crisis now demands.
Editor’s note: COP17 is scheduled to conclude on August 28, 2026. Several decisions remained under consideration during the summit’s closing process and should not be treated as adopted until finalized.
