André Braga Junqueira
  
André is a Brazilian ethnoecologist. He obtained his BSc. in Biological Sciences in 2005 from the Universidade de São Paulo (Brazil) and his MSc. in Botany in 2008 from the Instituto Nacional de Pesquisas da Amazônia (INPA - Brazil). He has been working in Amazonia since 2006, focusing on the use and management of plants by traditional populations. During his MSc. he studied the ecology and ethnobotany of secondary forests on terra preta, and from 2008 to 2010, as an associate researcher at INPA, he conducted research related to anthropogenic soils and forests, plant and landscape domestication, and Amazonian historical ecology. André obtained his PhD. from Wageningen University, within the Terra Preta Program, in September 2015. He is currently a post-doc researcher within the Terra Preta Program.
 
 
Short description of PhD thesis (research topic #9).
There is growing evidence that Terra Preta are specific environments that contrast strongly with non-anthropogenic soils not only in soil chemical and physical properties, but also in ecological and agrobiodiversity patterns. However, little attention has been given to the diversity of local knowledge, use and management strategies within Terra Preta, as well as to the drivers and implications of this diversity. Based on qualitative and quantitative approaches, this study aims to (1) understand how Terra Preta fits into local knowledge and perceptions about soils and how this relates to the ways these soils are managed; (2) analyse the relationships between socio-economic factors and floristic, structural and management characteristics of agricultural and agroforestry systems on Terra Preta and the underlying mechanisms that explain these relationships; (3) evaluate how the specific Terra Preta management strategies affect agricultural cycles and the rate of deforestation and (4) compare different agricultural and agroforestry systems within Terra Preta and between Terra Preta and non-anthropogenic soils regarding the ecological and livelihood services they provide.
