A debt-for nature swap (DfNS) is a method by which debt owed by a developing country or commercial/private company debtor can be renegotiated with the creditor to fund biodiversity conservation. A debt-for-nature swap occurs when the debt owed by the developing country debtor is exchanged with the creditor for financial payments made by the debtor country to conservation. These swaps can be done using either/or bilateral or commercial debt. The payments generated by debt-for-nature swaps often finance local conservation trust funds, which disburse grants to specific projects, or fund parks and protected areas.
