A Creative Way to Use Foreign Debt. A Case Study From Costa Rica
Written by: Elizabeth Aiken

Costa Rica’s Wide Implementation of Debt-for-Nature Swaps
In 2019, Costa Rica released an ambitious National Decarbonization Plan to achieve net-zero emissions by 2050, solidifying the small nation’s reputation as a global leader in sustainability. This article will comb through arguments and counterarguments that Costa Rica’s debt-for-nature swaps (DNS) have been a key factor in the nation’s success and provided crucial financial support for conservation and environmental initiatives. A DNS occurs when a country’s foreign debt is forgiven or reduced in exchange for a commitment to invest in environmental conservation efforts. In the late 1980s, organizations such as the World Wildlife Fund (WWF) established these swaps to combat deforestation in debt-burdened nations. Since 1989, the US debt-for-nature swaps canceled approximately $1.8 billion owed by 21 low- and middle-income countries and generated $400 million for conservation. While DNS have been instrumental in funding biodiversity protection and forest conservation, they also raise complex questions about sovereignty, economic impacts, and local perspectives.
Political Challenges
An initial political criticism of DNS was that it may infringe on the sovereignty of receiving nations. After the 1980s debt crisis in Latin America, plans were discussed to raise $4 billion and buy discounted Brazilian debt of roughly $8 billion in face value. In exchange, Brazil would invest in conserving the Amazon basin. However, following a 1989 visit by three U.S. senators, who reportedly promoted the case, Brazil rejected the DNS proposal. Foreign involvement in Brazil’s environmental conservation became increasingly seen as a system granting foreign powers undue control. Brazil viewed the debt crisis as caused by misleading loans from Western creditors. It therefore perceived DNS as legitimizing foreign-imposed debt. This underscores the challenge of implementing foreign investment programs like DNS the real or perceived undermining of sovereignty or reinforces debt-trap dependencies.
Implementation Considerations
Another criticism of DNS swaps is that they may not adequately incorporate local perspectives into their implementation. For example, in 2023 the Galapagos Islands signed a DNS that planned to cancel $1.1bn of Ecuador’s debt in exchange for investing $450m to protect the islands. However, its implementation did not undergo a consultation process with Indigenous peoples and other local communities. This highlights another key criticism of DNS, which is the difficulty of ensuring that community voices are included in the decision-making process for projects funded by these swaps. However, despite the challenge of involving local perspectives, many DNS-funded national park projects are regarded as outstanding successes for biodiversity conservation.
DNS and the Parque Nacional Guanacaste
One of these successful national parks is the Área de Conservación Guanacaste (ACG) in Costa Rica. ACG was designated a UNESCO World Heritage Site in 1999 and contains approximately 235,000 species (65% of the estimated species in Costa Rica) and 2.6% of global biodiversity. The majority of the funding for the successful ACG came from a groundbreaking 1989 DNS organized by Minister Alvaro Umaña and the Salomon Brothers, a New York investment bank. In this DNS, administrators brokered a $3.5 million debt swap donation from Sweden to provide $17 million in government bonds for long-term support for the Guanacaste project. This project set the stage for Guanacaste Park’s success, and from 1985 to 2019, ACG raised at least $107 million from national and international sources for long-term conservation.
Required Research
Despite this successful Costa Rican national park, other case studies suggest that more research may be needed to properly assess the conservation impact of DNS. Although DNS provides significant conservation funding, there is little cross-national research that evaluates whether such swaps correspond with a reduction forest loss. A growing body of research explores how bilateral aid for environmental projects affects forests. A 2009 study found that higher levels of bilateral aid for conservation were linked to increased forest loss rather than a reduction. A 2015 study published here observed the same pattern in Sub-Saharan Africa. Their research attributed this outcome to conservation programs that establish protected areas displacing local communities, forcing them to clear forests elsewhere. As a result, there is considerable complexity regarding the environmental impact of DNS and whether the harm they have been criticized for outweighing their successes.
Inflation Concerns
Another initial challenge of these swaps was a concern over inflation. DNS was established during the 1980s debt crisis when many nations increased exports in sectors like forestry and agriculture to pay their foreign debt, which strongly contributed to extensive forest loss. While DNS was proposed to help nations reduce debt and protect forests, Costa Rica halted debt swaps at the end of 1989 because of its potential macroeconomic impacts. When the swaps resumed they were more limited in scope. Compared to a simple cash deal, DNS swaps are also marked with two uncertainties: the value of the debt being swapped and the actual commitment to conservation. In a cash deal, the focus is solely on conservation efforts. With DNS, debtor countries oftentimes have an advantage over lenders when negotiating debt valuation because they alone know their true plans regarding repayment and conservation.
Debt-for-Nature Today
DNS swaps continue to occur today in Costa Rica and beyond, with Indonesia, El Salvador, Barbados, and the Bahamas being just a few countries that participated in DNS in 2024. In 2007, the U.S. and Costa Rica reached a DNS agreement to reduce Costa Rica’s debt by $26 million over 16 years, with the Bank of Costa Rica committing the funds to conservation efforts. In 2010, a second DNS was established between the two nations. This DNS signed for $27 million, reallocating the funds under the Forever Costa Rica Program and the United Nations’ global biodiversity framework. By 2023, 138 DNS-funded conservation projects were completed across Costa Rica’s protected areas. According to the study “Debt for Nature: A Swap Whose Time Has Gone?”, which reviews the performance of DNS programs in terms of their effectiveness in reducing deforestation and lowering debt servicing costs, the DNS mechanism has been used only modestly so far. However, in its latest form, DNS has become more streamlined. It now involves larger amounts of debt while providing greater financial support for environmental projects.
