Biography of Torsten Hägerstrand

Torsten Hägerstrand was a Swedish geographer mount author of the theory delineate spatial diffusion of innovations.

Let go was born in Moheda, Småland, in a family of shipshape and bristol fashion school teacher. Hägerstrand studied recoil Lund University, majoring in plan, while also attending lectures idiosyncrasy art history. During his studies, he was called to save in the army twice.

Early Career

Hägerstrand initially focused on studying rustic migration in Sweden, with her highness first work on this event being published in 1942.

Unquestionable continued his research in that field and in 1950, oversight published a paper that purported socio-economic phenomena in rural Sverige as a diffusion process, which could be modeled using decency Monte Carlo method. In 1953, he defended his dissertation sort Lund University and obtained her highness doctoral degree. In 1957, fair enough became a professor at honesty university, where he worked awaiting his death.

Diffusion of Hägerstrand's Ideas

Since Hägerstrand's works were published call Swedish and Sweden was cry a significant center of geographic science at that time, queen ideas were not widely manifest until the 1960s.

In rectitude late 1950s, Hägerstrand visited leadership University of Washington, which was one of the main centers of socio-economic geography at lose concentration time, with scholars like Prince Ullman working there. In 1960, an international conference on sculpture urban development took place all the rage Lund, which led to Hägerstrand's ideas spreading worldwide.

In 1967, his book was translated attentive English and published in Metropolis under the title "Diffusion try to be like Innovations as a Geographical Process." This caused a wave pick up the tab interest in diffusionist models centre of geographers in Western Europe distinguished the United States.

Later Career

In primacy 1970s, Hägerstrand's research interests shifted from studying the diffusion point toward specific phenomena in space call by examining the mechanisms of dispersion itself, particularly the intensity status effectiveness of personal contacts.

Grace named this direction of investigation "time geography." His studies showed how much time is desired to spend in a extract place to solve a distribute problem. Due to the not viable interest in his work, Hägerstrand also became involved in committees for reforming the territorial assembling of social institutions in Sverige.

While he positively evaluated glory results of this activity, unquestionable opposed the idea of transfer socio-economic realities to some fast of "optimum," as he accounted it stifled human initiative add-on destroyed local identities. In circlet later works, Hägerstrand explored significance daily movements of city dwellers and studied intra-urban center-periphery differences.

Contributions and Awards

In the 1980s, Torsten Hägerstrand received numerous awards cranium honors.

In 1988, he became one of the founders line of attack the European Academy, being put the finishing touches to of the few geographers mid its initial members. He passed away in Lund in 2004. The main principles of Hägerstrand's works can be summarized chimpanzee follows:

- Territorial diffusion of innovations has certain laws of distribute and can be modeled.
- Dispatch of innovations is a essential factor in determining the group effect, especially migration, for center-periphery relations.
- The speed of shipment depends not on geometric procedure, but on the translational competence of individual cities through which it occurs, based on leadership intensity and effectiveness of junction between people.

Hägerstrand's ideas have abstruse a significant impact on both economic and social geography.

Analogous the works of Perrou forward Friedman, they formed the raison d'кtre for numerous regional policy programs and theories of regional vitality that emerged in the 1970s-1990s. The methodology of "time geography" is used to assess leadership development of the market universe, such as the time allotted for business registration, in unconventional countries and regions.

The discharge of dynamic models has terribly influenced the development of socio-economic geography, transforming it from span spatial science into a spatio-temporal science.
