The Amazon basin contains over half of the world’s remaining tropical rainforest, and is facing unprecedented changes that will have major impacts on biodiversity, regional hydrology and the global carbon cycle. Avoiding tropical deforestation requires implementation of forest management strategies that provide revenue opportunities for those living in or near forests, thus creating incentives for forest conservation via management. Carapa guianensis is one species that provides this opportunity; this tropical tree is valued for the high quality oil extracted from its seeds and its mahogany-like timber. Resource use, such as logging and non-timber extraction, however, incurs associated environmental costs. Effective management can mitigate these costs when based on an understanding of the ecological parameters under which sustainable harvest can exist.
Dr. Christie Klimas (Assistant Professor, De Paul University, Chicago, Ill, USA) is engaged in answering these questions. She used coupled economic ecological models to answer the question: Under what ecological and market conditions is collection of C. guianensis seed oil favored and, conversely, under what ecological and market conditions is C. guianensis timber harvest favored? THer Ph D study took place at the Brazilian Agricultural Research Institute’s 1,200 hectare research forest in Acre, Brazil.
