Building a Sustainable Africa Together

​Congo Basin Institute

UCLA and the International Institute of Tropical Agriculture are leading a multi-institutional initiative to develop the Congo Basin Institute (CBI), which will be a model for how universities can partner in international development. CBI is based at a research and education campus located in Yaoundé, Cameroon and offers lab and meeting space, accommodations, and assistance applying for research permits. CBI researchers conduct science that decision makers can use to address sub-Saharan Africa’s interlocking environmental and development challenges.  Please visit the CBI website for more information about getting involved with CBI or conducting research in Cameroon.

dja reserve

Dja Reserve

For the past 20 years, we have been conducting research in the Dja Biosphere Reserve and adjacent areas.  The Dja Biosphere Reserve is a UNESCO World Heritage site located in South Central Cameroon. The reserve comprises over 500,000 hectares, making it one of Central Africa’s largest protected areas. Our research began in 1993 with the...

long-distance movements and resource use by hornbills in cameroon

Long-distance Movements and Resource Use by Hornbills in Cameroon

The recent discovery by UCLA Center for Tropical Research (CTR) scientists that the large-bodied frugivorous hornbills (Ceratogymna sp., Fig. 1) of Central Africa make long-distance movements (Fig. 2) highlights their potential as important seed dispersers that help maintain the incredible tree diversity found in the Congo basin. Until the discovery that their abundance in particular...

mapping evolutionary processes under climate change

Mapping Evolutionary Processes Under Climate Change

The Partnership for International Research and Education project seeks to develop an integrated framework for conserving central African biodiversity under climate change that is both evolutionary-informed and grounded in the socioeconomic constraints of the region.

Rainforest Biodiversity and Speciation

Region: Africa (Cameroon, Equatorial Guinea, Ivory Coast), Australia, South America (Ecuador) These projects seek to understand the mechanisms important in generating rainforest biodiversity. Results from research on birds in Cameroon and reptiles in Australia strongly suggest that these transition zones, known as ecotones, are an important generator of the biodiversity of the rainforest. These findings...

rainforest restoration and seed dispersal

Rainforest Restoration and Seed Dispersal

Region: South America (Ecuador) Africa (Cameroon) These long-term studies examine the role of birds and primates as seed dispersers in the maintenance of tree diversity in West African and Neotropical rainforests. In West Africa, we are using data gathered at a remote field station (maintained by CTR and ECOFAC) in the Dja Reserve, (a UN...
