The United Nations has issued a stark warning regarding the escalating crisis of land degradation, emphasising that an annual investment of £260 billion is essential to avert a catastrophic future where vast areas of arable land deteriorate into dust. Currently, only a fraction of this funding—approximately £56 billion—is being mobilised, placing millions at risk of forced migration, conflict, and severe disruptions to global food supply chains.
The Financial Shortfall
Yasmine Fouad, the executive secretary of the UN Convention to Combat Desertification (UNCCD) and former Egyptian environment minister, highlighted the urgent need for innovative financing solutions to bridge the significant funding gap. “Today, there is a massive gap between the finance available and the finance required,” she stated. “Closing that gap cannot rely on public budgets alone. We need the financial sector, development banks, insurance systems, and private capital to treat healthy land as foundational infrastructure for our economies and societies.”
According to the latest UNCCD assessment, a staggering $355 billion (£261 billion) is necessary each year to effectively address the issue of land degradation. At present, only $77 billion is being mobilised annually, with 72 per cent originating from the nations most threatened by land degradation. Government aid contributes around 22 per cent, while private investment accounts for a mere 6 per cent. As global aid budgets decline, there is a pressing need to develop mechanisms that can attract more private financing to fill this void.
Understanding Land Degradation
Land degradation encompasses the decline in land quality and productivity due to factors such as soil erosion, deforestation, and overgrazing. Desertification, specifically, refers to persistent land degradation in dry regions, leading to diminished productivity and the expansion of arid conditions—an alarming development for agriculture and livestock.
Fouad warned that the consequences of inaction are no longer confined to the environment. “Land degradation and drought contribute to food insecurity, supply chain disruptions, forced migration, rising inequality, and instability in vulnerable regions,” she explained. “In a deeply interconnected world, no country is insulated from these impacts. Investing in land restoration is therefore not charity; it is preventive investment in resilience, stability, and shared prosperity.”
A Growing Crisis
Recent data reveals that land degradation is worsening globally, with 15.4 per cent of reported land classified as degraded in 2019, marking a 4 per cent increase over four years. This deterioration equates to over 100 million hectares of once-productive land being lost annually, affecting approximately 1.3 billion people. The UNCCD estimates that the economic toll on affected countries is staggering, costing them about 2 per cent of their GDP each year—roughly $878 billion—through impacts on food availability, soil fertility, and groundwater replenishment.
This urgent message has resonated with the environment ministers of the G7, who recently characterised desertification and drought as “systemic global challenges” and “security risk multipliers” in their communique ahead of the upcoming G7 leaders’ summit.
Solutions on the Horizon
Despite the gravity of the situation, Fouad remains hopeful that adequate funding can unlock viable solutions. “We are backing projects like watershed management in Ethiopia and Kenya, and initiatives encouraging farmers in the Nile Delta to cultivate salt-resistant crops,” she noted. One of the prominent UNCCD initiatives, the Great Green Wall project across the Sahel region of Africa, aims to plant 100 million hectares of trees in desert-affected countries by 2030. In addition, 74 drought-prone nations have submitted drought management plans to the UNCCD, which now require funding for implementation.
A pivotal moment will arise in August when the UNCCD convenes a “Conference of Parties” (COP) in Ulaanbaatar, Mongolia, focusing on strategies for financing desertification mitigation efforts. While scepticism regarding the efficacy of such conferences is growing, Fouad believes they are crucial for fostering international collaboration. “I see COPs as more important than ever,” she asserted. “They are vital for bringing together countries from both the global North and South to reach the consensus necessary to address various global environmental challenges.”
Why it Matters
The ramifications of failing to address land degradation extend far beyond environmental concerns; they pose existential threats to food security, social stability, and international peace. As the global community grapples with increasing climate challenges, the need for robust financial mechanisms to support land restoration initiatives has never been more critical. Investing in sustainable land management is not merely an environmental imperative; it is an essential strategy for ensuring future resilience and prosperity for all nations.
