What Can Changes In Infrastructure In Etelä-Haaga Tell Us About Spatial Social Mixing?
In his lecture, Joel Jalkanen described how a group of researchers at the University of Helsinki have been looking at complex problems of how to present dynamic, functioning-enabling communities on a map in a way that can be treated with spatial prioritisation methods. They have mapped different attributes of ecological communities that are known to relate to ecosystem functioning, such as species richness and biomass. This data from Joel Jalkanen has been used to make visualisations in maps in this QGIS Practical.
This week’s practical allowed to me to explore the topic I am interested in writing my thesis about: perceived safety. Being able to covert crowd-sourced data into GIS regarding this topic is a very useful skill to learn!
Here is an excerpt of this week’s practical.
I found an interesting article on participatory planning in the city I grew up in and thought I’d write a short reflection.
Nicolas Webb has been working on an ‘alternative masterplan’ for the city, which aims to encourage people to invest and use commercial services in Newport over the nearby hubs of Cardiff and Bristol.
My original plan aimed to look at historical photographs and use them to determine how Haaga’s current infrastructure could be optimised. Critique of this approach argued that there was a need to apply more of a human approach to the project.
Reflecting on this, I concluded that my original description of my project over-emphasised the historical photographs angle. Instead, I aim to create a type of timeline of Haaga’s infrastructure and link to spatial-social mixing.
This week’s theme is socio-spatial differentiation and segregation. In his Master’s Thesis, Andrey Zhukov addressed if ethnic spatial segregation has increased in Helsinki. In it, he claims the earliest study into this was in 2002, by Kauppinen. This illustrates that socio-spatial segregation is new concept challenging Welfare State model.
In her lecture, Venla Bernelius addressed this, making the interesting point that “poor people are like the Star Trek final frontier – they go where no-one else goes”. Furthermore, Bernelius argued that segregation is growing in Helsinki, leading to larger areas of disadvantage. This GIS practical will explore if this is the case – that there are areas of Helsinki Metropolitan Area (HMA) which have high concentrations of people with low income and education levels.
Lee et al. (2011) conducted a cluster analysis of workplace space typologies in California. The study created 14 categories of urban workplace type, spanning from CBD-style to marginally urbanised areas. This study utilised colour coded maps (See Figure 1) to visualise the results of the study. However, this type of study does not provide an indication of which types of jobs are present in each area. Therefore, this GIS practical will plot heatmaps showing the densities of employment typologies, which has implications in land use and services planning.

This is a brief excerpt from GIS Practical 6, completed with Sirpa Ojansuu, Jaana von Denffer and Nyurguyana Pavlova.
The task of developing a research question for Haaga based on the first three assignments of studio work is challenging. However, I shall give it a go.
The most obvious starting point is to review my own posts on Haaga. Of my own posts, I most enjoyed writing the Beyond Wikipedia task, where I wrote about Huopalahti railway station. In that post I explored historical photos of the station and compared them to a 2002 “modern” photo (I visited the station after I wrote that post and realised yet more changes have occurred since 2002). This makes me think that I want to explore more historical photographs of the Haaga area.

Building efficiencies are becoming increasingly important in urban life. Hoyle & Downton (2002) argue that the “dream of the quarter acre block has become a nightmare; petrol costs too much, the water is running out, the kids live too far from their friends and the houses are behind fences”. They also state that future cities should aim to be walking cities, reducing overall ecological footprints. Working on this principle, this practical aimed to examine the current building efficiency scores of Helsinki, Finland.
