Natalia is a Post-doctoral Researcher in Biodiversity Monitoring and Climate Change Adaptation in LINCZ (Locally-led Indigenous Nature-based Solutions to Climate Change Adaptation in Zimbabwe) Project.  She supports the project through the application of spatial analysis to monitor landscape-scale outcomes of nature-based solutions for restoring forest, wetland, and degraded agricultural lands, and for protecting and enhancing biodiversity in the areas of interest. 

Prior to joining CMU, she worked as a Remote Sensing and Geoprocessing  Researcher at Brazilian Agricultural Research Corporation (Embrapa) with focus on monitoring deforestation and forest degradation in the Amazon Forest. Also worked at Cargill being responsible for palm oil mapping in Latin America and with sustainability projects, such as the development and management of web applications of traceability, from agricultural crop production chain in compliance of the environmental laws in force at national level and international certifications.

On general, Natalia has with research focus is monitoring land use and land cover and environmental changes, including forest response to multiple environmental stressors, and carbon accounting, combining different datasets, with the aim of identifying the main actors responsible for transformations and modifications in/of landscapes, in order to understand the temporal and spatial dynamics occurring in geographic space to support conservation efforts and policies.

Natalia holds a BSc in Geography from Federal Universty of Santa Catarina (Brazil), a MSc and PhD in Remote Sensing from National Institute for Space Research (Brazil).
