To face the myriad environmental challenges around the world we need professionals trained in both in science and policy to understand and tackle environmental issues, both here and abroad. The Nicholas School of the Environment and Earth Sciences at Duke University is designed to train environmental professionals who will work within the private and public sector to sustain the environment, and those who will work within academic and other research institutions to understand the human impact on our planet.

Currently, the Nicholas School manages programs in over a dozen countries.  Some of their international collaborations are listed below:

Nicholas School Division of Earth and Ocean Sciences: Bolivia
Decade-long research project on the sediments of Lake Titicaca (Bolivia) to ascertain past fluctuations in climate at tropical latitudes in South America.
Nicholas School Program in Ecosystem Science and Management
ARIDnet, a National Science Foundation sponsored effort to develop a network for testing new paradigms for global desertification, comparing sites in North and South America.
Nicholas School Program in Environmental Economic and Policy: Indonesia
Several past joint research projects at Bogor Agricultural University, sponsored by the Asian Development Bank and the MacArthur Foundation, and a nascent collaboration to develop a joint exchange program between their Tropical Marine Resource Economics Program and the Master of Environmental Management Program of the Nicholas School. 
Nicholas School, Duke Marine Laboratory:
Oak Fellowship Program, brings students from various countries in Central America to pursue an MEM degree in the Coastal Environmental Management Program
Cetacean By-Catch Resource Center, sponsored by the World Wildlife Fund, serves as an online clearinghouse for information, statistics, news, inquiries, scientific papers, technological advances and the latest developments in cetacean bycatch mitigation.
Ocean Biogeographic Information Systems, Spatial Ecological Analysis of Magavertebrate Animal Populations (OBIS-SEAMAP), to provide a global tracking and analysis of the population and migration pathways of large marine vertebrates
Duke Wetlands Center: Studies of Iraq Marshlands    
Nicholas School faculty serve on the Agency for International Development (AID) team to evaluate the status and potential remediation of Iraq wetlands
Nicholas School Program in Energy and Environment: Kenya
Cooperative agreement with Moi University in Kenya.  MOU signed with The School of Environmental Studies at Moi University to support cooperation between the two universities in studies of environmental issues in Kenya.
Nicholas School Program in Conservation Biology:
Field studies in Madagascar of the ecology and conservation of fossa (Cryptoprocta ferox) and other predators in Madagascar, and analysis of deforestation in Madagascar using satellite images and remote sensing techniques.  These are not unrelated projects, inasmuch as habitat destruction is the major cause of species extinction in Madagascar.  The work is performed in cooperation with the University of Antananarivo and funded by Conservation International, Earthwatch Institute, the National Geographic Society and NSF.
Cooperative studies with the Peace Parks Foundation, to explore the ecological viability of trans-boundary parks, especially for elephant populations
Center for Tropical Conservation:
Field Station at Cocha Cashu, Peru
Duke researchers have established and managed the Cocha Cashu Biological Station in Manu National park
Parks Watch Program to monitor the status of protection in natural areas
