Osvaldo Valeria

His research project was undertaken at Waswanipi Cree Model Forest, an area managed by the Aboriginal community using a mosaic method over the last 10 years. Mr. Valeria estimated the cost of this type of management practice while considering other uses of the forest. He developed a spatial platform tool that enables forest managers to take into account concerns of trappers and community members, in particular Waswanipi Crees. Mr. Valeria joined UQAT in June 2003 as a research professor specialized in development of forest management tools using geomatics and remote sensing. His PhD experience will contribute to improving knowledge on evaluating and integrating non-timber resources into forest management planning. His interests lie in the development of models that will integrate Aboriginal knowledge into management practices in Québec.


His research interests include development and design of spatial platform decision support systems in forest management. These will integrate forest operations, system analysis, economic and financial analysis and modeling. Forest certification (master’s thesis) is also among his interests.

Research orientations

  • Spatial modeling of timber harvest, evaluation of supply costs, and evaluation of advantages and disadvantages for other forest users.
  • Forest operations planning and development of decision support systems.
  • Optimization of harvest and transportation systems.
  • Certification of forest practices.
