In the forests near the southern Sumatran village of Krui, 48-year-old Marhana climbs up the trees to harvest damar, a resin used in paints and varnishes. These damar trees are part of something called an "agroforest," which experts see as a way to prevent deforestation and conversion of forests into palm oil plantations.

Palm oil plantations have led to widespread deforestation in Indonesia. But now some farmers are turning to a different crop — damar, a kind of anti-palm oil, grown in forest-based farms.
