United Nations Convention to Combat Desertification
Land degradation is not just an environmental problem. It increases risks to human health and the spread of new diseases. It is a driver of forced migration and conflicts over scarce resources. It is a leading contributor to climate change, biodiversity loss, poverty, and food insecurity. In other words, it is at the core of sustainable development.
Up to 40% of the world’s land is degraded. Between 2015 and 2019, at least 100 million hectares of healthy and productive land were degraded every year—a cumulative area twice the size of Greenland. Droughts are hitting more often and harder all over the world, driven or amplified by both climate change and poor land management.

Restoring degraded land and soil, and investing in drought resilience, are some of the most cost-effective actions countries can take to reduce the high human, social and economic impacts of drought—simultaneously increasing food, water and energy security while reducing displacement and conflict drivers. Thirty years ago, with the adoption of the United Nations Convention to Combat Desertification (UNCCD), countries agreed to walk together down this path.
What Drives Land Degradation and Desertification?
Land degradation is the long-term decline in the quality of land that leads to the reduction or loss of the biological or economic productivity of land. In the drylands, land degradation is known as desertification. According to the Global Land Outlook, drylands cover more than 45% of the Earth’s land surface, provide 44% of the world’s agriculture, support 50% of the world’s livestock, and are home to one in three people worldwide. Experts estimate that, if not reversed, land degradation will drive 700 million people out of their homes by 2050 because they will no longer be able to feed themselves or have access to sufficient water.
The dominant drivers of land degradation include agriculture and related land-use changes, unsustainable management or over-exploitation of resources, natural vegetation clearance, nutrient depletion, overgrazing, inappropriate irrigation, excessive use of agrochemicals, urban sprawl, pollution, mining and quarrying, among others.
Deforestation is one of the most significant causes of land degradation. Tree roots help bind soil particles, thus maintaining their quality. When trees are cut down, the soil particles tend to disperse, negatively impacting the quality of the soil.
Another driver of land degradation is a lack of land tenure security. When people own their land, they are more likely to make the long-term investments needed to sustainably manage land, such as practicing crop diversity and agroforestry. Even though land constitutes the main asset from which the rural poor derive their livelihoods, millions of farmers, especially women, do not own their land. In many countries, the laws or customs hinder women’s ownership of land. In more than 100 countries, women are dispossessed from their land when they lose their husbands. This is a key issue to global land restoration since women are more likely to invest in diverse food systems, which boost soil health, while men focus primarily on cash crops and monoculture.
What is the UN Convention to Combat Desertification?
In 1991, African environment ministers decided to prioritize their proposal for the negotiation of a new convention to combat desertification as one of the concrete recommendations to be adopted at the UN Conference on Environment and Development (UNCED or Earth Summit) to be held in Rio de Janeiro, Brazil in June 1992. They hoped a convention would help them gain access to additional funding to combat desertification, land degradation, and drought.
Leading into the final days In Rio, delegates had reached agreement on much of the desertification chapter of Agenda 21, the UNCED outcome, including the definition of desertification: “Land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climate variations and human activities.” However, there was still opposition to a convention. Many developing countries resisted the idea of a special convention for Africa, since they also faced land degradation. Industrialized countries maintained that desertification was a local problem and did not warrant a treaty. It wasn’t until the final hours of the Earth Summit that a deal was finally struck and the call for a convention was included in Chapter 12 of Agenda 21.
Negotiations on the Convention began in May 1993 and were completed in five meetings over fifteen months. At the first session in Nairobi, Kenya, the International Negotiating Committee held a one-week seminar to inform negotiators of the substantive issues related to desertification and drought, demonstrating that land degradation affected people around the world. This led to a serious discussion on how to create a global convention that still gave priority to Africa. When Committee Chair Bo Kjellén suggested including a special annex for Africa under the Convention, other regions insisted on annexes for their regions.
At the second meeting in Geneva, Switzerland, in September 1993, governments agreed to negotiate four annexes simultaneously, while giving special attention to Africa. In the end, the Convention includes regional implementation annexes for Africa, Latin America and the Caribbean, Asia, and the Northern Mediterranean. A fifth annex, for Central and Eastern Europe, was adopted in 2000.
Differences over financial resources nearly caused the negotiations to collapse. Developing countries called for a special fund as the centerpiece of the new convention. Industrialized countries rejected binding obligations to increase financial assistance to affected countries, insisting that existing resources could be used more effectively. The deadlock was broken only after the United States proposed establishing a “Global Mechanism” to improve monitoring and assessment of existing aid flows and increase donor coordination. Many developing countries were not happy, but believed they had to accept the Global Mechanism on the final night because if there was no agreement on finance, there would be no convention. On 17 June 1994, delegates adopted the UNCCD, four regional implementation annexes, and a resolution calling for urgent action for Africa.
The Convention recognizes the physical, biological, and socio-economic aspects of desertification and the importance of redirecting technology transfer so that it is demand-driven. The core of the convention is the development of national, subregional and regional action programmes by national governments in cooperation with donors, local populations, and non-governmental organizations (NGOs). In fact, the Convention was the first to call for the effective participation of local populations and organizations in the preparation of national action programmes. This innovation led the first “sustainable development” convention to also be referred to as a “bottom-up” convention.
The UNCCD was opened for signature in October 1994 and entered into force on 26 December 1996. Today, there are 197 parties, representing universal ratification.
Released in 2024, Unite for Land provides an overview of the first 30 years of the UNCCD.
Promoting Land Degradation Neutrality
In 2008, a group of scientists was asked by the UNCCD Executive Secretary to examine if the Convention could use the offsetting principle already practiced by the Convention on Biological Diversity (CBD) and the UN Framework Convention on Climate Change (UNFCCC), and applied to deforestation at one site by planting trees elsewhere. The idea was to use this offsetting principle to lead to zero-net land degradation and expand the reach of the Convention to address land degradation globally, not just in the drylands.
The Secretariat and like-minded countries then advocated for endorsement of this concept of land degradation neutrality (LDN) by the UN Conference on Sustainable Development (Rio+20) in June 2012 and its inclusion as one of the targets under the Sustainable Development Goals (SDGs). This would enable LDN to gain traction and effectively link land degradation as a driver of poverty, climate change and biodiversity loss, and demonstrate the relevance of productive land to global sustainability. The Rio+20 outcome, The Future We Want, highlights the need for urgent action to reverse land degradation and achieve a land-degradation neutral world.
After Rio+20, the UNCCD pushed forward with LDN on a variety of fronts. First, in 2013, the 11th meeting of the Conference of the Parties (COP) established a working group to develop a science-based definition of LDN (Decision 8/COP.11). In late 2014, the Secretariat set up the LDN pilot project, through which 14 affected countries worked to translate LDN into national targets.
Meanwhile, in New York, the UNCCD and its supporters successfully lobbied for including a target on LDN in the Sustainable Development Goals (SDGs). When the 17 SDGs and 169 targets were adopted by the UN General Assembly in September 2015, they included target 15.3: “By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world.” For the first time, the UNCCD had successfully placed an item at the forefront of the international agenda.

The following month, UNCCD COP12 convened in Ankara, Turkey, and endorsed the science-based definition of LDN submitted by the working group:
“Land degradation neutrality is a state whereby the amount and quality of land resources necessary to support ecosystem functions and services and enhance food security remain stable or increase within specified temporary and spatial scales and ecosystems” (decision 3/COP.12).
And, in what some viewed as a ‘game changing’ accomplishment, COP12 agreed that striving to achieve SDG target 15.3 is a “strong vehicle for driving implementation of the UNCCD,” and invited countries to set voluntary targets to achieve LDN. The Global Mechanism and the UNCCD Secretariat established the LDN Target Setting Programme to assist countries in setting national baselines and creating voluntary national LDN targets and associated measures. Since then, 131 countries committed to setting LDN targets and more than 100 have already set their targets.
In 2017, the Convention’s Science-Policy Interface (SPI) published the Scientific Conceptual Framework for Land Degradation Neutrality, which provides a scientific foundation for understanding, implementing and monitoring LDN. It was designed as a bridge between the vision and the practical implementation of LDN by defining LDN in operational terms. The SPI developed three indicators, which created a clear pathway for monitoring LDN—both for the Convention and SDG 15.3:
trends in land cover;
trends in land productivity or functioning of the land; and
trends in carbon stocks above and below ground.
But there were concerns. Some countries and members of civil society at COP12 were worried about the focus on LDN as a central UNCCD target. Some likened it to opening a door to land grabs and greenwashing. So while the UNCCD COP called for the restoration of 1.5 billion hectares of land by 2030 to achieve a land-degradation neutral world, it was also essential to acknowledge land rights and inclusive land governance arrangements at the national and sub-national levels. The land tenure decision at COP14 did just that.
Already countries have pledged to restore 1 billion hectares of land, but there is still more work to be done to make these pledges a reality.
2018-2030 Strategic Framework
In 2017, COP13 in Ordos, China, adopted the UNCCD 2018−2030 Strategic Framework, which has three main components: a vision, strategic objectives and an implementation framework.
The vision commits parties to “A future that avoids, minimizes, and reverses desertification/land degradation and mitigates the effects of drought in affected areas at all levels and strive to achieve a land degradation neutral world consistent with the 2030 Agenda for Sustainable Development, within the scope of the Convention.”
The Framework’s five strategic objectives are designed to guide the actions of all UNCCD stakeholders and parties until 2030:
To improve the condition of affected ecosystems, combat desertification/land degradation, promote sustainable land management and contribute to land degradation neutrality
To improve the living conditions of affected populations
To mitigate, adapt to, and manage the effects of drought in order to enhance resilience of vulnerable populations and ecosystems
To generate global environmental benefits through effective implementation of the UNCCD
To mobilize substantial and additional financial and nonfinancial resources to support the implementation of the Convention by building effective partnerships at global and national level
The implementation framework defines the roles and responsibilities of parties, UNCCD institutions, partners and stakeholders in meeting the strategic objectives.
In Abidjan, Côte d’Ivoire, in 2022, COP15 launched a midterm evaluation of the Strategic Plan. The results of this evaluation, overseen by an intergovernmental working group, will be discussed at COP16, which is expected to adopt a decision on enhancing the implementation of the Strategic Framework for its final five years and restoring the necessary hectares of land to achieve a land degradation neutral world.
What’s Next?
UNCCD COP16 convenes in Riyadh, Saudi Arabia, from 2-13 December 2024, under the theme “Our Land. Our Future.” The COP will commemorate the 30th anniversary of the UNCCD and a special segment will bring together leaders and high-level officials to commit to accelerate action to combat land degradation and desertification and improve drought resilience.
A social media image for UNCCD COP 16 underlines how land degradation is a youth issue.
In addition to the midterm evaluation of the Strategic Plan and adopting the UNCCD’s biennial budget, COP16 is expected to negotiate and adopt decisions aimed at:
accelerating restoration of degraded land between now and 2030;
boosting drought preparedness, response and resilience;
ensuring land continues to provide climate and biodiversity solutions;
boosting resilience to sand and dust storms;
scaling up nature-positive food production by protecting and restoring grasslands and rangelands;
enhancing ongoing efforts to address desertification/land degradation and drought as one of the drivers that causes migration;
strengthening women’s right to land tenure to advance land restoration; and
promoting youth engagement, including decent land-based jobs for youth.
COP16 is also expected to catalyze new initiatives on land restoration and drought resilience that build on the G20 Global Land Initiative.
For the first time, the COP will include an Action Agenda, which will highlight voluntary commitments and actions and include thematic days:
Land Day on 4 December will focus on the importance of healthy land for combating climate change, creating jobs and alleviating poverty, with an emphasis on nature-based solutions, land restoration, and private sector engagement.
Agri-food System Day on 5 December will highlight sustainable farming practices for resilient crops and healthy soils while protecting ecosystems.
Governance Day on 6 December will address inclusive land governance.
People’s Day on 7 December will focus on the role of youth, women and civil society in decision-making.
Resilience Day on 10 December will focus on policies and technologies to build societal and planetary resilience in the face of climate change.
Finance Day on 11 December will engage financial stakeholders to showcase innovative funding mechanisms and partnerships for land and drought resilience initiatives.
COP16 will also build upon the COPs of the CBD in October 2024 and the UNFCCC in November 2024, improving synergies between the three “Rio Conventions” and promoting the implementation of the SDGs.
As UNCCD Executive Secretary Ibrahim Thiaw said in his foreword to the second edition of the Global Land Outlook report, “Governments and stakeholders cannot stop the climate crisis today, biodiversity loss tomorrow, and land degradation the day after.” The international community needs to tackle all these issues together. Achieving climate, biodiversity and sustainable development goals is impossible without healthy land.
In 1994 the adoption of the UNCCD started the world down the path to reversing land degradation, desertification and drought. COP16 is expected to reaffirm this global commitment for present and future generations.

As the detrimental effects of the East African Crude Oil Pipeline (EACOP) project intensify, hundreds of Ugandan communities are bearing the brunt of this colossal project. From forced evictions and displacements to the criminalization of project critics and now devastating flash floods, the urgency of addressing these issues is paramount. The suffering of local communities hosting the project has been exacerbated.
In Kyotera District, central Uganda, communities remain stranded as floodwaters rush into their homes and gardens, destroying their food stores and leaving families in despair. Residents attribute the cause of the floods to the ongoing construction activities related to the EACOP project.
Kyotera is one of the 10 districts that the project traverses to the port of Tanga in Tanzania; the others include Hoima, Kikuube, Kakumiro, Kyankwanzi, Gomba, Mubende, Lwengo, Sembabule, and Rakai.
The EACOP project, a 1,444km pipeline that will transport oil from Hoima in Uganda to the port of Tanga in Tanzania, has cast a wide net of impact. It has affected thousands of people, especially in local communities, leading to displacement, destruction of property and crops, and environmental hazards such as floods.
The development of oil activities in Uganda has led to several major projects supporting oil extraction, processing, and export. The proponents of these projects argue that they bring economic development and job opportunities to the region.
These include the EACOP project, the Tilenga Project operated mainly by Total Energies (with partners like CNOOC and UNOC), which covers oil fields located in Buliisa and Nwoya districts, and the Kingfisher Project, which is managed by the Chinese oil company CNOOC and is located on the southeastern shores of Lake Albert (mainly in Kikuube District). It focuses on drilling oil and setting up a central processing facility (CPF), and oil camps and access roads have been constructed to support these operations.
However, these developments have not left the communities the same. Instead of bringing only the promised prosperity, they have contributed to poverty, fear, and uncertainty among the local populations and have exacerbated the climate crisis.
It is also worth noting that activists who stand up to defend these communities face a different kind of suffering: harassment, surveillance, arrests, and even physical attacks. They have been criminalized under vague charges, often labeled as enemies of development for demanding transparency, fair compensation, and environmental protection.
For the communities in Kyotera, the construction of an access road leading to the EACOP camp in the Kyotera district, which serves as a base for project operations, blocked drainage channels, causing water to overflow into the neighboring villages.
The floods, which started last month in April, have now affected seven households in Kyakacwere village, Kakuto Subcounty, Kyotera district.
People’s houses and gardens are flooded, forcing them to look for alternative places to live, and several plantations, such as banana plantations, maize, and beans, among others, continue to be affected. The impacts have already caused dispossession to the affected communities and are likely to cause financial losses and food insecurity for smallholder farmers and their families.
Noeline Nambatya, a 47-year-old mother and a person with disability, shares her traumatic experience of waking up to a flooded house. “This has never happened to us. I found my house full of water in the morning, and several of my household items had already been destroyed. We want justice, we can’t stay in this situation. We were living peacefully, and now, because of the so-called investors, this is what we are reaping.” She revealed in an interview with the Witness Radio team.
The disaster left her home logged, her crops destroyed, and her livelihood distorted. Currently, the caretaker of eight faces immense challenges in providing for her family, including feeding and supporting them in school. The adverse situation forced her and the family to relocate to the nearby village of Muyenga.
Another affected person, Lukyamuze Paul, claims the floods have caused significant damage, including cracking houses and severely destroying crops. He holds the EACOP project responsible for the devastation, stating that when the access road leading to the EACOP camp was constructed, it blocked existing drainage channels, changing the natural water flow into people’s homes.
The environmental concerns arising from EACOP project activities, such as floods, continue to affect different project host communities. The problem was first experienced in Bulisa district in 2022 when Total Energies began the construction of the Tilenga feeder pipeline, resulting in floods that affected surrounding communities.
Patience Nabukalu, who has experienced climate-related flooding, joins protestors from around the world to deliver a letter to CEO Georges Elhedery criticising the financing of oil, gas and coal projects.
At nine years old, Patience Nabukalu was devastated when her friend, Kevin, died in severe flooding that hit their Kampala suburb, Nateete, a former wetland. Witnessing deaths and the destruction of homes and livelihoods in floods made worse by extreme rainfall has had a profound impact on her.
She decided to try to bring about change – to do what she could to amplify the voices of those in the Ugandan communities worst affected by the climate crisis.
Now 27, Nabukalu is one of several young climate activists who travelled to London this week to attend what has been predicted to be the last in-person AGM held by HSBC. They will deliver a letter to the bank’s CEO, Georges Elhedery, urging him to stop financing the expansion of oil, gas and coal projects and harmful industrial agribusiness, and to stop providing money to companies that forcibly remove people from their homes to make way for such infrastructure.
“This is an opportunity to talk to real people, not just an HSBC office,” said Nabukalu, speaking before the meeting at the Intercontinental hotel. “I will be so happy to get the chance to hand over the letter and to ask: ‘Has HSBC measured the damage they have done by financing corporations that are driving the climate crisis?’”

The letter refers to a 2023 Action Aid report, which identifies HSBC as “the largest European financier of fossil fuels in the global south”, channelling $63.5bn (£48bn) into fossil fuel activities between 2016 and 2022.
The letter to Elhedery, from young people all over the world, refers to HSBC’s plans, announced earlier this year, to review its commitment to scaling back its financing of fossil fuels.
“This has made something very clear: you value profit margins and boardroom agendas more than the lives of millions of people bearing the full brunt of your decisions,” the letter reads.
Environmentalists criticised HSBC after it delayed key parts of its climate goals by 20 years, and watered down environmental targets in a new long-term bonus plan for Elhedery that could be worth up to 600% of his salary. In February, the lender said it was reviewing its net zero emissions policies and targets – which are split between its own operations and those of the companies it finances – after realising its clients and suppliers had “seen more challenges” in cutting their carbon footprint than expected.
The activists’ letter asks “that you not only stand by your commitments to end your support for the fossil fuel industry in line with what the science requires, but also put an end to all lending and underwriting for corporations involved in fossil fuel expansion”.
Nabukalu will also urge the bank to stop funding corporations that are backing the east African crude oil pipeline from Uganda to Tanzania. Once constructed, the pipeline would produce an estimated 379m tonnes of CO2 over 25 years. The main backers of the multimillion-dollar pipeline are the French oil company TotalEnergies and the state-owned China National Offshore Oil Corporation (CNOOC).
Nabukalu, who has visited people living along the proposed route, said: “This pipeline is already causing damage even before its construction. Thousands and thousands of people have been displaced. They were promised land titles, but have none. Their livelihoods have been sabotaged. They cannot build agriculture, the water table is low, so they have little access to water.
“These people should be at the centre of the bank’s decisions.”
“We will talk to HSBC and ask them to stop financing fossil fuels that are driving the climate crisis,” said Nabukalu. “By continuing to finance TotalEnergies they are destroying our future.”
A report published in April found that those displaced along the pipeline’s proposed route had reported being inadequately compensated and rehoused.
Some western banks have declined to fund it after pressure from a coalition of organisations and community groups.
A spokesperson for HSBC said: “We follow a clear set of sustainability risk policies which support our ambition to align the financed emissions in our portfolio to net zero by 2050. We do not comment on client relationships.”
In January, a joint team of soldiers and police evicted more than 400 local people who had been occupying part of the 64 square kilometre Maruzi ranch in Apac District. The most affected were actually residents of Acam-cabu Village.
Acam-cabu Village is no longer a recognised administrative unit in northern Uganda’s Apac District after it was erased from the map of Uganda following a land dispute.
Since this area is now excluded from the list of existing villages in the country, a total of 1,040 people living in 180 households there cannot now benefit from any government programmes and projects.
Mr Bosco Wacha, the LCI chairman of Acam-cabu, said the village disappeared from the map of Uganda around 2018.
“Since 2018, I have not been getting my salary and the people who have been isolated because of this confusion are suffering,” Mr Wacha said on the phone on Thursday, May 1, 2025.
He also said all the households in the lost village are at risk of extreme hunger and starvation because the government has stopped them from engaging in any farming or economic activities.
“There is a severe shortage of food here because we have been stopped from farming. We are not able now to take our children to school and we lack access to healthcare,” said Mr Joe Olwock, the area chairman of the National Resistance Movement (NRM) party.
Mr Felix Odongo Ococ, Akokoro LC3 chairman, said that although the government doesn’t recognise Acam-cabu as a village in Uganda, during the National Population and Housing Census, 2024, enumerators went and counted people there.
Data obtained from the local leadership of this isolated administrative unit shows that there are 180 households in Acam-cabu. Of these, at least 14 households have one member each and eight households have eight members.
However, a household regarded as number eight in the document that was reportedly sent to the Office of the Prime Minister (OPM) has the highest membership, standing at 11 people. This household is followed by number 158, which has 10 members, and household number eight has a total of nine members.
Dr Kenneth Omona, the Minister of Northern Uganda, previously said he would meet the leadership of Apac to try to iron out all issues affecting the community in the district.
In January, a joint team of soldiers and police evicted more than 400 local people who had been occupying part of the 64 square kilometre Maruzi ranch in Apac District. The most affected were actually residents of Acam-cabu Village.
The squatters, numbering over 1,500 occupied the said land around 1995. They had repeatedly ignored various eviction notices, saying the land belongs to their fore grandfathers.
In September 2015, the High Court in Lira issued an interim order blocking Apac District leadership from evicting the affected residents. The district then resorted to using the army and police to evict the squatters.
The Uganda People’s Defence Forces (UPDF) has established a military detachment to man security of the area.
