Mercedes Bustamante is a biologist born in Chile. Most of her work takes place in the savannah regions in Brazil called the cerrado biome. Her area of interests are studying large scale impacts on the environment, land usage and biogeochemistry.[1] Since 1994 she has been a professor at the University of Brasília (UnB), where she is currently the Graduate Coordinator of the Ecology Department. She is a member of the Climate Crisis Advisory Group.[2]

Education edit
Bustamante attended the University of Rio de Janeiro, graduating with a Bachelors in Science with a Biology focus in 1984. She received her master's degree in Agricultural Physiology/Plant Physiology from the University of Viçosa in 1988, and she acquired a PhD in Geobotany from the University of Trier in 1993.
Achievements edit
- In 2007 Bustamante received the Claudia prize in the science category for preservation of native areas.
- She was awarded woman of the year for her conservation work in the cerrado.
- Working Group III: Mitigation of the 5th Report of the Intergovernmental Panel on Climate Change (IPCC): Dr. Bustamante was a coordinator on working on “Agriculture, Forestry and Other Land Uses”. This mainly focuses on emissions from deforestation, livestock, and soil and nutrient management.[3]
- United Nations Environment Program (UNEP): Worked on writing a report on nitrous oxide.
- International Nitrogen Initiative (2010-2013): Represented Latin America during this time period.
- Scientific Committee of the International Geosphere Biosphere Program (IGBP) & Biosphere Atmosphere Program in the Amazon (LBA): A member of these two organizations focusing on global changes and scientific research.
- Ministry of Science, Technology and Innovation (2010-2013): General coordinator for Ecosystem Management, Director of Policies, and Thematic Programs.
- Brazilian Programs and Scholarships of Coordination of Personnel Development: Director of this program.
- Advisory Committee of the Ecology and Limnology: A member of this group.
Research achievements edit
Bustamante's research group has made several important discoveries about the impacts of human activities on the Cerrado. For instance, she was one of the first to link cattle ranching in the Cerrado to greenhouse gas emissions.
Government service edit
In addition to her academic research, Bustamante served in Brazil's federal government. She was a General Coordinator of Ecosystem Management and Director of Policies and Thematic Programs in the Ministry of Science, Technology from 2010 to 2013. Her responsibilities included political outreach, and working alongside lobbyists.

Books edit
- Our Nutrient World: The challenge to produce more food and energy with less pollution: This book discusses agriculture will continue to be a large business in the future. The fertilizers used such as nitrogen and phosphorus will still be in high demand. These nutrients have led to large scale negative impacts on the planet leading to soil degradation, food scarcity, and depleting natural resources.[4]
- Amazonia and Global Change: This book discusses the future the Amazon faces with climate change approaching. Some issues addressed are increased emissions, differences among wet and dry seasons, drought, release of carbon, floodplains, and cattle ranching.[5]
Ecosystem Lab edit
The Ecosystem Lab is part of the University of Brasília (UnB), and was created in 1994.[6] The lab is dedicated to researching the tropics at different levels. The lab specifically focuses on the cerrado biome. The lab consists of Dr. Bustamante's bachelors, graduate, masters, and PhD students.
