- Summary - More countries linking debt cost to conservation goals - Seychelles, Belize, Barbados among those to strike deals - Ecuador swap could be biggest yet at $800 million - Cape Verde, Sri Lanka and others also exploring deals SHARM EL-SHEIKH, Egypt, Nov 17 (Reuters) - The Galapagos Islands, whose thousands of unique species inspired Darwin's theory of evolution, have incalculable ecological value."There's now a big push to get nature into sovereign debt markets," said Simon Zadek, executive director at NatureFinance, which advises governments on debt-for-nature swaps and other types of climate-focused finance.At their simplest, these deals see expensive bonds or loans written down and replaced with cheaper financing, usually with the help of a credit guarantee from a multilateral development bank.Ecuador, for example, is in talks with the Pew Charitable Trusts plus the Inter-American Development Bank and U.S. International Development Finance Corporation, two of the people with knowledge of the planned deal said.The World Bank's managing director of operations, Axel van Trotsenburg, told Reuters on the sidelines of COP27 that it supports debt-for-nature swaps, as did African Development Bank President Akinwumi Adesina, who said his bank would "absolutely" start providing credit guarantees."
