CORRECTION: COP15: Global GDP could gain $140 trillion a year, if we achieve the objectives of the UN Convention to Combat Desertification

The global economy could increase by more than $140 trillion a year [1], or 1.5 times the annual global GDP, if the objectives of the United Nations Convention to Combat Desertification (UNCCD) are achieved, participants heard during a side-event at the 15th summit of the UNCCD.

Camilla Nordheim-Larsen, Senior Partnerships and Resource Mobilization Coordinator at the UN Convention, noted that action in the land sector has the potential to generate up to $140 trillion a year and create 400 million new jobs, while failure to act can result in losses in the range of $44 trillion. The Sustainable Development Goal for Life on Land is least funded, but can contribute most to resilience, she said, speaking at an event on innovative finance mechanisms for sustainable landscapes, hosted by the African Development Bank and partners.

The cost of taking action may seem vast but governments could pay an even higher price if they do nothing. “The benefits of taking action against land degradation largely outweigh the costs of sustainable landscape management. In Sub-Saharan Africa, it is by at least seven times [2]! Inaction costs Sub-Saharan countries $490 billion per year, while according to the Economics of Land Degradation Initiative, action to reverse land degradation could generate benefits worth up to $1.4 trillion,” said Luc Gnacadja, former Executive Secretary of the UN Convention to Combat Desertification and former Minister of Environment of Benin, currently acting as a Co-Chair of the Adaptation Benefits Mechanism Executive Committee.

Rishabh Khanna, Chief Impact Officer at Earthbanc and a steering committee member of the Initiative of Land, Lives and Peace, presented a new initiative launched together with the UN Convention at the summit — digital sustainable land bonds, which allow carbon buyers to purchase at an earlier stage of development. “Finance for land and ecosystem restoration makes up less than 1% of all climate finance due to a lack of universal capital market products for these activities. Part of the reason is that monitoring, reporting and verification of sustainable land management has been labor-intensive, sometimes inaccurate and uses fragmented measurement and accounting methodologies.”

The Adaptation Benefits Mechanism, piloted by the African Development Bank between 2019 and 2023, certifies and monetizes the environmental, social, and economic benefits of adaptation actions, including for sustainable and resilient landscapes. “Unlike for mitigation, where cost-efficiency is the driving factor for investments, revenues from monetizing the adaptation benefits are likely to be directed towards actions in vulnerable communities that are needed most, because they deliver compelling stories,” explained Gareth Philips, Climate and Environment Finance Manager at the African Development Bank.
