Most of the current research projects of the group involve elements of both themes, making them strongly intertwined. The work conducted by the group is oriented towards applied research, dealing with many timely problems and challenges in the Finnish society, including the currently ongoing health care reform, spatial reorganization and logistical challenges of social and health care services, and the changing health needs of the ageing population. The applied research is supported by a more generally oriented geospatial analysis of the regional and urban structure, and population dynamics in Finland.
Research group description
Research group is closely involved in environmental research, carried out in co-operation with physical geographers. Some of these research efforts are related to spatial ecology and environmental change in the North, whereas others concern the influence of the physical environment, air impurities, and ambient temperature on the incidence of diseases and public health in general.
GIS-based methods (Geographic Information System) are used extensively by the research group to address the problems presented in the different projects. In some cases, the GIS-based approach is coupled with statistical techniques, aiming at both explorative and predictive modeling of spatial and societal phenomena. The research carried out by the group involves the use of a wide range of geospatial datasets, including data on transportation networks (for accessibility, location and routing problems), population structure, as well as built and natural environment alike. In addition, population cohort datasets, used in co-operation with epidemiologists, constitute an important part of the study of the geography of health and well-being.
The research group is engaged in software development for the automatization of GIS-based tasks and implementation of spatial algorithms, providing means to manage data processing workflows and analysis procedures independent of the capabilities of the mainstream GIS software.

Determinants and lifecourse trajectories of physical activity and sedentary behavior at middlife
The aim of this study is to identify the features of the built and natural environment associated with physical activity (PA) and sedentary behavior (SED) and evaluate how changes in the built environment are associated with the changes in PA, and explore the lifelong determinants and trajectories of PA and SED in respect to residential environment. The study population is the Northern Finland Birth Cohort 1966.
The features associated with PA and SED and their lifelong trajectories are studied in respect to health, health behavior, socioeconomy, personality and work related factors. The changes in built and physical environment from 31 to 46 years of age are studied by utilizing the geographic information system (GIS) and geographical data, such as the home coordinates of the cohort members, YKR-data, Digiroad and Lipas sports facility data.
The physical inactivity is one of the leading causes of death, and promoting physical activity is a public health priority. The knowledge produced in this study can be utilized in urban planning, education, planning of interventions and in evidence based decision making.

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 considerable 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 undernutrition 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. The aim of the study is to explore the spatial mismatch between proxies of food production and consumption in accurately localised data.

A selection of previous, completed projects
Quantification and valuation of ecosystem services to optimize sustainable re-use for low-productive drained peatlands (LIFEPeatLandUse)
The aim of the project was to produce GIS-based maps to demonstrate the predicted impacts of peatland re-use options on ecosystem services. This was done by developing a decision support system, in which ecological and economic information were transformed into land use options such that the benefits from ecosystem services are safeguarded. The monetary value of the land use options were maximized under given constraints regarding biodiversity, environmental loading and GHG emissions, in order to fulfil the constraints set in the regional, national, and EU level policies. The implemented system was used to optimize the re-use of low-productive drained peatlands, which is a key issue concerning peatland use in Finland.
