Provide land resource management, geographic information systems and geomatics support to local, regional and national scale research programs at the Fredericton and Charlottetown Research and Development Centres.

Research and/or project statements

Provide GIS and geomatics support to the following projects:

  • Soil microbial biogeography and soil health in agro-ecosystems of Atlantic Canada
  • Microfauna biogeography and artificial intelligence in Atlantic agri-environmental ecosystems
  • Development of regional management strategies and decision making tools for the control of Colorado potato beetle
  • Surveying the extent of triazine resistant lamb's quarters (Chenopodium album) and development of an integrated weed management program for potato production systems
  • Assessing the ecological goods and services provided by riparian areas and identifying areas at risk in agricultural landscapes in Atlantic Canada
  • Landscape Integrated Soil and Water Conservation (LISWC) on sloping fields under potato production in Atlantic Canada
  • Living Laboratories Initiative
