How debt deals are funding the fight against ecosystem collapse

Yet recognition is growing that nature loss poses serious risks to political stability.  "Nature is a foundation of national security," the authors from the UK Department for Environment, Food and Rural Affairs (DEFRA) wrote in a recent assessment that draws a direct line between protecting critical ecosystems and the future stability of the country.  Biodiversity loss threatens the water, food, clean air, and critical resources on which human societies depend. And the risk isn't just from local nature decline. The report warns that six critical ecosystem regions — including the Amazon Rainforest — could collapse by mid-century, threatening the security of the UK and other countries both at home and abroad.  That's because collapse of critical ecosystems even far away disrupts a delicate balance that can "drive displacement of millions, change global weather patterns, increase global food and water scarcity, and drive geopolitical competition for remaining resources," said the report. Among the most immediate risks is food insecurity. More than a third of the world's ocean fish stocks are already overfished, while more than three-quarters of global food crops depend on pollinators that are vanishing due to intensive agriculture. As ecosystems weaken, supply shocks become more likely — and more politically destabilizing.  The vulnerability is acute in the UK, which imports 40% of its food and does not have enough agricultural land to support the nation's current dietary patterns. In the US, between 75 to 90% of the country's seafood comes from imports. In an increasingly volatile world, disruptions abroad can translate into price spikes and shortages at home.  "Protecting and restoring ecosystems improves food system and societal resilience to shocks," wrote the DEFRA. Swapping stocks and shares for investing in nature The challenge of protecting nature and mitigating security risks is financial as much as ecological. For economically vulnerable countries facing heavy debt burdens, the short-term revenue from logging and resource extraction can be difficult to resist.  ​​​The world collectively spends US$7.3 trillion (€6.2 trillion) on activities that harm nature, 30 times more money than it spends on protection, according to the United Nations Environment Program.    What's needed is a dramatic inversion in spending, environmental advocates say. Enter debt-for-nature swaps, an increasingly popular financial tool aimed at unlocking new capital to protect vital ecosystems. The idea dates back to the 1980s. A creditor and a country exchange debt for commitments to protect nature. The country gets its debt restructured or canceled on the condition that some of those savings are spent on conservation programs. ​​In the early days, the creditor was either a conservation NGO or a government, and the deals were relatively small. ​​ The first swap took place in 1987 between Conservation International and Bolivia. The nonprofit bought some of Bolivia's debt, so that the country could spend more money to protect the Beni Biosphere Reserve in the Amazon River basin.How Belize chocolate supports rainforest conservationTo view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Despite domestic concerns over sovereignty and infringement on Indigenous lands, the swap helped strengthen protection for forest reserves and spark a wave of similar debt-for-nature deals across Latin America.  More recently, a 2021 swap in Belize helped th​​e country reduce its ballooning debt burden, ​​while funneling millions in savings into managing fisheries and marine conservation. "If you protect certain areas of the ocean, they act as an incubator for fish stocks elsewhere," said Gaia Larsen, who oversees climate finance for developing nations at research nonprofit World Resources Institute. As fish populations decline globally, such protections may prove essential for keeping food on plates. More than 3 billion people rely on seafood as a major source of protein. A new era of private funding for nature protection  For private investors, the appeal is bond-like returns. Legal & General, the UK's largest asset manager, recently pledged $1 billion to new debt-for-nature swaps, the firm told DW in an emailed statement. "We believe these tra
