This is a brilliant example of using logic and business sense to preserve our forests. I wish more NGOs adopted this approach.

A MOST unusual document landed on your correspondent’s desk recently: a financial report from a rainforest. Iwokrama, a 370,000-hectare rainforest in central Guyana, announced that it was in profit. It added, more intriguingly, that rainforests had entered the “global economy”.

Iwokrama is part of the largest expanse of undisturbed rainforest in the world, which overlies the Guiana Shield. It has a unique history. In 1989 the president of Guyana had the foresight to give the forest as a gift to the Commonwealth for research into global warming. Today it is administered by an international board of trustees, who have devolved the day-to-day management to the Iwokrama International Centre. It is this centre that has been working to exploit the forest sustainably.

Edward Glover, one of Iwokrama’s board of trustees, says that it became clear more than a decade ago that the forest could not rely on donor funding to survive, so it had to look elsewhere for finance. The centre’s first job was to identify the forest’s assets and to exploit them. It seems to have perfected its art. Today the centre makes money in areas such as ecotourism, timber-extraction, forest-products such as honey and oils, bio-prospecting and forestry research. Its results for 2008 reveal that it made a surplus for the first time that year, with revenues of $2.4m and a profit of $800,000. The previous year it had lost $200,000. Revenues from timber were up by 44%, ecotourism by 26% and training by 22%.

When forests vanish, people suffer. That is why many believe that there is an urgent need to bring forests onto the global financial balance sheet. Last year Pavan Sukhdev, an economist at Deutsche Bank, reported that the world was losing natural capital worth between $2 trillion and $5 trillion every year as a result of deforestation alone. If money could be made by selling these ecosystem services, then the financial equation for forests would change.
