The United Nations Convention to Combat Desertification (UNCCD) COP17 ended in Ulaanbaatar with two stories that deserve to be told together.
The first is a story of progress.
Land tenure remained firmly on the international land agenda. Rangelands and pastoralists received unprecedented attention. New financing was mobilized for restoration and drought resilience. Indigenous Peoples, local communities, women, youth, scientists, governments, and others brought knowledge and demands into a global conversation about the future of land.
The second story is much less comfortable.
An unprecedented number of issues were blocked or postponed. Negotiations on drought failed to produce the stronger global response many countries had sought. Discussions on gender, civil-society participation, and cooperation among the three Rio Conventions were blocked at the beginning of the conference. Migration, aspects of drought and aridity planning, and knowledge sharing and technology transfer were among the matters pushed to COP18.
These are not peripheral questions. They concern how the world responds to drought, how women participate in land governance, how civil society contributes to implementation, how knowledge moves between countries, and whether international environmental agreements can work together on problems that are inseparable in the real world.
COP17 therefore raises a question larger than land degradation.
What happens when the requirement for consensus stops facilitating cooperation and starts preventing it?
COP17 achieved more than the negotiating impasse suggests
It would be wrong to characterize Ulaanbaatar simply as a failed COP.
The UNCCD reports that governments, development banks, funds, and companies advanced a US$1.3 billion portfolio for land restoration and drought resilience across 23 countries. The Rangelands Flagship Initiative brought together US$1.2 billion across 45 projects, which the Convention describes as its largest single mobilization for rangelands. UNCCD and Luxembourg also launched the Drought Resilience Investment Facility, designed to mobilize up to US$400 million in public and private capital.
Rangelands themselves moved closer to the center of international land policy. That matters for tenure security. Rangelands cover more than half of the Earth’s terrestrial surface, and their governance frequently depends on collective rights, customary institutions, mobility, negotiated access to water and grazing resources, and forms of tenure poorly captured by conventional ideas of individual ownership. COP17 discussions explicitly connected sustainable rangeland management with legitimate land rights for pastoralists and Indigenous rangeland communities.
Land tenure also emerged in its own negotiated decision, alongside a decision on rangelands and pastoralists. The official COP17 record includes adopted texts on both issues.
These developments matter. Secure land and resource rights are not an optional social dimension of restoration. They influence who can use land, who makes decisions about it, who bears the costs of restoration, and who ultimately benefits.
That is precisely why the political difficulties at COP17 should concern us.
What was blocked
The independent Earth Negotiations Bulletin account of COP17 uses unusually strong language. It reports that the sheer number of issues blocked or postponed was unprecedented in the history of the Convention.
The United States played a prominent role.
At the opening plenary, the U.S. blocked agenda items concerning gender, civil-society participation, and synergies among the Rio Conventions. The move helped set the tone for what became two difficult weeks of negotiation. Other substantive issues, including migration, drought, aridity, and knowledge sharing, also failed to advance.
It is important to be precise here. The United States was not alone in disagreeing with other Parties on every issue, nor should every failure at COP17 be reduced to the position of one government. Multilateral negotiations involve legitimate differences over obligations, finance, national circumstances, and institutional mandates.
But neither should diplomatic caution obscure what happened.
When one Party can prevent even the consideration of issues supported by many others, we are dealing with more than an ordinary policy disagreement. We are confronting a structural weakness in the way multilateral decisions are made.
Consensus is valuable. A veto is something different.
I believe strongly in multilateralism.
That belief is precisely why COP17 should prompt a discussion about reform.
Consensus has real advantages. International agreements are more durable when governments genuinely support them. Negotiators should exhaust every reasonable effort to reconcile differences, accommodate national circumstances, and find language countries can implement.
But consensus and unanimity are not the same thing.
Nor should a commitment to consensus mean that 196 Parties must indefinitely surrender their ability to act because one Party refuses to join them.
The UNCCD has lived with this unresolved problem for almost its entire existence. Its rules contain a long-standing unresolved provision, Rule 47, concerning decision-making when consensus cannot be reached. The issue appeared repeatedly on COP agendas from the Convention’s earliest years, but Parties never resolved it. UNCCD’s own archive records decisions on Rule 47 stretching across successive COPs.
After COP17, that procedural question no longer looks obscure.
It looks fundamental.
It is time to talk about voting
The principle should be straightforward: seek consensus first, but do not make unanimity a prerequisite for action.
Parties should negotiate seriously. They should accommodate minority concerns where possible. On consequential matters, the threshold for a vote should be high.
But after good-faith efforts to achieve consensus have been exhausted, a qualified majority of Parties should be able to make decisions.
That could mean a two-thirds or other appropriately high threshold. The precise mechanism deserves careful negotiation. Safeguards would also be needed to ensure that voting did not simply allow powerful blocs to override smaller or poorer countries.
But the underlying principle deserves consideration: multilateralism cannot function indefinitely if participation gives every government an effective veto.
Voting would not eliminate disagreement. It would make disagreement visible.
Governments could vote no. They could abstain. They could explain their positions publicly and seek to change the decision at a future COP.
That is normal governance.
What is harder to defend is a system in which a country can prevent the international community from reaching a decision at all.
This is not an argument against the United States
The immediate temptation after COP17 is to make this an argument about one country.
That would miss the larger point.
Today, the obstruction may come from the United States. At another COP, on another issue, it may come from another government or group of governments.
Rules should not be designed according to whether we agree with the country using them.
The question is whether the rules themselves are fit for purpose.
The United States has every right to oppose an international drought instrument or object to language it considers outside the Convention’s mandate. Other governments have the same right.
But a right to disagree should not automatically become a right to prevent everybody else from deciding.
That distinction is central to functioning democratic institutions at the national level. International institutions increasingly need to confront it as well.
The problems themselves are already multilateral
Drought does not respect borders.
Neither do dust storms, ecosystem decline, climate impacts, commodity markets, migration pressures, or many of the economic forces affecting land use.
The UNCCD itself describes drought as a challenge affecting food and water security, public health, ecosystems, economic stability, and sustainable development across regions.
The answer to difficult international negotiations is therefore not retreat from multilateralism.
It is stronger multilateralism.
We need institutions capable of bringing nearly 200 countries together, listening to competing interests, incorporating science and local knowledge, protecting the interests of countries with less geopolitical power, and reaching compromises.
But eventually, they also need to be capable of deciding.
Land governance offers the same lesson
There is a parallel here with land governance itself.
Secure and equitable land governance depends not on the absence of disagreement, but on institutions capable of managing disagreement legitimately.
People have overlapping claims. Customary and statutory systems interact. Pastoralists need mobility across administrative boundaries. Governments pursue public objectives. Communities assert collective rights. Women and men may have profoundly unequal power within the same household or tenure system.
Good governance does not pretend those differences disappear.
It establishes rules through which rights are recognized, evidence is considered, people can participate, decisions can be challenged, and ultimately decisions can be made.
International governance should aspire to the same standard.
TenureSecurity.org exists in part because land and resource governance cannot be understood through technical solutions alone. It is about rights, institutions, evidence, participation, accountability, and power. That is the platform’s independent editorial proposition: connecting evidence and practice while making room for the people and communities whose rights and knowledge are too often peripheral to formal decision-making.
COP17 demonstrated both what multilateralism can accomplish and what happens when its procedures become vulnerable to paralysis.
The lesson from Ulaanbaatar should not be that international cooperation has failed.
It should be that international cooperation matters too much to allow it to fail this way.
Consensus should remain the ambition. It should not remain an unlimited veto.
The time has come for the UNCCD Parties to reopen the question they have postponed for decades and develop a fair mechanism for decision-making when genuine consensus proves impossible.
The world will continue to face drought, land degradation, climate change, biodiversity loss, and growing competition over natural resources regardless of whether 197 governments can agree on every paragraph of a negotiated text.
Multilateralism must be able to accommodate disagreement.
It must also be able to act.
