How can we save the Amazon rainforest? It’s a question that is becoming increasingly urgent as concern grows that the world’s largest original forest – a key defense against global warming – risks being destroyed by farming, logging and climate change.
One solution may lie partly in private hands.
In 1990, the government of Brazil created a system of private nature reserves, known as RPPNs, to complement state-owned national parks. Under the law, the land must be protected, but it may be used for research, education and eco-tourism to provide income. In return there are tax advantages for owners.
Today there are 700 RPPNs across Brazil, protecting almost one million hectares.
