Co-founder and managing trustee, Masungi Georeserve Foundation
Together with her sister Ann, Billie Dumaliang runs award-winning conservation and sustainable tourism project Masungi Georeserve. Situated just to the east of Manila, it protects historic limestone formations and hundreds of plant and animal species, many of them threatened, with 3,000 hectares of heavily degraded land reforested since the 2000s. Employing many of those formerly involved in the exploitation of the land, it also provides clean water to neighbouring communities.
