Biography

I am a doctoral student of Physical Geography and my research interests are related to the ecosystem services across spatial scales. I use Geographic Information Systems (GIS) -based accessibility analysis to explore people’s ability to utilize different ecosystem services and to estimate the negative impacts which ecosystems can cause for people. My special interest is to introduce the accessibility analysis in the ecosystem service research. At my current project, I study the balance between supply and demand of ecosystem services at continental and global scales.

Research interests

  • Ecosystem services
  • Geographic Information Systems (GIS)
  • GIS approaches for analyzing accessibility, supply and demand of ecosystem services

Global geographic accessibility to food resources: Exploring spatial mismatch between food production, consumption and transport system by using big and open source data

Despite of satisfactory level of global food production, shortage of food is still a huge problem in some of the less-developed countries. Future climate change, population growth and conflicts likely increase the problem, whereas developing farming practices and opportunities to boost fair markets may ease off the hunger problem. However, regional balance between production and consumption, as well as differences in transport system conditions among regions, have a key role in satisfying demand. Aim of the study is to explore spatial mismatch between proxies of food production and consumption in accurately localised data. Two year project is funded by Kone Foundation.
