Koti keskellä kaupunkia : Keskusta lapsiperheen asuinalueena, esimerkkeinä Tukholma ja Helsinki

Families with children have traditionally moved to suburbs. In the last 20 years a modest counter process has however been recognized. Families with an urban lifestyle stay in the city centres. This study looks at the phenomenon through two cases, Stockholm and Helsinki. In the first case it has already been observed that the city centre has grown in popularity among families with children. Therefore it serves as a basis for the study and as well as a point of comparison. Stockholm’s city centre is expanding as new neighbourhoods have been built and are being planned. In the city centre of Helsinki the building of two large neighbourhoods for 30 000 inhabitants will start in a few years. The first aim of the study is to look closer at what has really happened in the city centre of Stockholm, why families choose to live there with their children and how the City of Stockholm has reacted to the change. The main sources of information are secondary sources, statistics and interviews with planners, politicians and experts in the field. The main object is to look at the situation in the city centre of Helsinki. Can a preference for urban residential environments be observed in Helsinki? What are the reasons for a family to choose the city centre as a living place? How does the everyday life of a family in the city centre appear? How are these families taken into account in the planning of the city? The main sources of information here are statistics, interviews with dwellers in the neighbourhood Kruununhaka and interviews with planners. In Stockholm the birth rate has grown constantly during the 2000s and is highest in the city centre. Some of the families still move elsewhere, but many of them do not. One of the most important reasons for living in the city centre is short working distances which give working parents more time with their children. Another reason is a preference of an urban, active lifestyle. Families prefer to live close to everything, childcare, schools, shops and entertainments. The popularity of the city centre among families with children has taken politicians and planners by surprise. Helsinki has not experienced a baby boom like Stockholm. However the negative changes in the birth rate have been more modest in the central areas than in the suburbs. Statistics show, that many families move away from the city centre as the children grow. Families who stay in the city centre especially appreciate closeness to public and private services and good public transportation which means that they are not dependent on using the car. Further they find that the city centre has a tolerant climate and is a safe and beautiful place to live in. The families enjoy the social life of the neighbourhood and feel that it makes a good climate to raise children in. However they are concerned with traffic safety and the lack of stimulus in the playgrounds of the neighbourhood parks. Two large neighbourhoods with homes for about 30 000 inhabitants are now planned in the former Port Districts in the city centre of Helsinki. The other one, Jätkäsaari has been planned to become an attractive alternative for families with children. Traffic safety has been one of the main objects for the planning. The other, Kalasatama, has been planned to attract all groups in society.

Asemakaavoitus Helsingin seudun kasvun hallinnassa

Many Finnish municipalities need to control their growth. In this research growth is understood as developments of land utilisation and also as a wide range of other changes that have mainly ap-peared as a result of a long term growth in population. The development growth control contains four areas: 1. adequate productivity of town planning, 2. stationing the growth to needs led and for sustainable developments, 3. quality of the developing environment, and 4. producing growth with communicative and transparent process. The aim of the research is to represent connection between town planning and development growth control. Research defines the role of town planning in the municipalities development growth control. In addition research focuses on links between town planning and development growth control in history, present and in the development work for the future. According to the hypothesis the extensive examination of town planning enables better growth control and promotes appropriate response to municipal changes regarding housing delivery. As an example there are five outskirt municipalities in the Helsinki region. They are called Kirkkonummi, Vihti, Nurmijärvi, Tuusula and Sipoo. The decision was to use examples based on a contingence theory. According to the theory there is no one correct way to operate. Therefore development should be based on individual municipal needs. In the research, municipality s needs were collected by 20 semi- structured interviews from municipal officials. In addition there were group interviews in Uusimaa Regional Council and in Uusimaa Regional Environmental Centre. There was also secondary material collected from official papers and statistics. Operationalisation was the analysis tool between empiric and literature reviews. The role of town planning has evolved during the 20th century from a more simple town plan level to operative stage in town planning hierarchy. Outskirt municipalities town planning was established during the 1960s. Since then one of the most important aims in the town planning has been to produce growth and building possibilities. Currently the challenge is to reach the satisfying rate of productivity and to meet increased housing demand. Other challenges include locating the appropriate geographical areas for growth; and the balance between required developments and planning permission decisions. Findings concluded that town planning should be more viable and it should have better ability to co-operate and operate in the changing operational environment. Municipality s ability to receive growth can increase and growth control can advance by planned and workable town planning. It is essential to take wide perspective of the each municipality's unique needs to improve productivity rather than to focus simply on productivity.

Accessibility as a determinant of opportunities : A case study from Peruvian Amazonia

Accessibility is a crucial factor for interaction between areas in economic, cultural, political and environmental terms. Therefore, information concerning accessibility is relevant for informed decision making, planning and research. The Loreto region in the Peruvian Amazonia provides an interesting scene for an accessibility study. Loreto is sparsely populated and because there are few roads in the region, in practice all movement and transportation happens along the river network. Due to the proximity of the Andes, river dynamics are strong and annual changes in water level combined with these dynamic processes constantly reshape accessibility patterns of the region. Selling non-timber forest products (NTFP) and agricultural products (AP) in regional centres is an important income source for local rain forest dwellers. Thus, accessibility to the centres is crucial for the livelihood of local population. -- In this thesis I studied how accessible the regional centre Iquitos is from other parts of Loreto. In addition, I studied the regional NTFP/AP trade patterns and compared them with patterns of accessibility. Based on GPS-measurements, using GIS, I created a time-distance surface covering Loreto. This surface describes the time-distance to Iquitos, along the river network. Based on interview material, I assessed annual changes to accessibility patterns in the region. The most common regional NTFP/AP were classified according to the amount of time they can be preserved, and based on the accessibility surface, I modelled a catchment area for each of these product classes. -- According to my results, navigation speeds vary considerably in different parts of the river network, depending on river types, vessels, flow direction and season. Navigating downstream is, generally, faster than upstream navigation. Thus, Iquitos is better accessible from areas situated south and south west of the city, like along the rivers Ucayali and Marañon. Differences in accessibility between different seasons are also substantial: during the dry season navigation is slower due to lower water levels and emerging sand bars. Regularly operating boats follow routes only along certain rivers and close to Iquitos transport facilities are more abundant than in more distant areas. Most of the products present in Iquitos market places are agricultural products, and the share of NTFP is significantly smaller. Most of the products were classified in product class 2, and the catchment area for these products is rather small. Many products also belonged to class 5, and the catchment area for these products reaches up to the edges of my study area, following the patterns of the river network. -- The accessibility model created in this study predicts travel times relatively well, although in some cases the modelled time-distances are substantially shorter than observed time-distances. This is partly caused by the fact that real-life navigation routes are more complicated than the modelled routes. Rain forest dwellers having easier access to Iquitos have more opportunities in terms of the products they decide to market. Thus, they can better take advantage of other factors affecting the market potential of different products. -- In all, understanding spatial variation in accessibility is important. In the Amazonian context it is difficult to combine the accessibility-related needs of the local dwellers with conservation purposes and the future challenge lies in finding solution that satisfy both of these needs.

Kaupunkipurot Helsingissä - Veden laatu vuonna 2004

In recent years urban hydrology and individual urban streams have been in focus and subjects to research also in Helsinki. However, until now there has been lack of research covering simultaneously the whole area of the city of Helsinki. The aim of this study was to find out the general state of water quality in small urban streams in the city of Helsinki. 21 streams were studied: Mätäjoki, Korppaanoja, Mätäpuro, Näsinoja-Tuomarinkylänoja, Tuomarinkartanonpuro, Kumpulanpuro, Tapaninkylänpuro, Tapaninvainionpuro, Puistolanpuro, Longinoja, Säynäslahdenpuro, Viikinoja, Porolahdenpuro, Mustapuro, Marjaniemenpuro, Mellunkylänpuro, Vuosaarenpuro, Rastilanpuro, Ramsinkannaksenpuro, Skatanpuro and Yliskylänpuro. Water samples were collected from 48 sampling points, each stream having at least one point. Four water samples were collected from each point, sampling periods being 9.-11.2., 26.-28.4., 29.6.-1.7. and 25.-27.10.2004. Field measurements associated with water sampling included water temperature, oxygen concentration, pH and electrical conductivity. Water samples were analysed in the Laboratory of Physical Geography in the University of Helsinki and in the Environmental Laboratory of the City of Helsinki Environment Centre for following properties: suspended solids, dissolved substances, alkalinity, principal anions and cations (Na+, K+, Mg2+, Ca2+, F-, Cl-, NO3-, PO43- and SO42-), colour, turbidity, biological and chemical oxygen demand (BOD7 and CODMn-values), nutrient concentrations and bacterial indicators of hygienic quality. The main water quality issues found in this study were low oxygen levels in many streams and poor hygienic quality at least occasionally. E.g. in summer oxygen levels were under 60 % in every stream. Amount of total dissolved substances and nutrients were high in some of the streams studied. Compared to other Finnish streams the values of alkalinity and pH were higher. Although these problems were common, the variation between different streams and sampling points was significant. This was probably due to local conditions. Best overall water quality was found in Mätäpuro and Tuomarinkartanonpuro streams. Seasonal variation was evident in almost all water quality properties. For example the total amount of dissolved substances was largest in winter and decreased during the year. Colour and turbidity were smallest in winter and increased towards the end of the year. The same was true for suspended solids, which had smallest concentration in winter and greatest in autumn. It must be kept in mind that the spring samples were collected after the spring flood otherwise the largest suspended solid concentrations would have been expected in spring. Finnish general water quality classification was used to assess the quality of urban stream waters. Its suitability for small urban streams is not, however, completely trouble-free. This classification does not take into account the quick changes in such small streams but evaluates only the yearly mean values. This can oversimplify the picture of the water quality situation in the streams. Also in order to better reflect the urban environment the analysed water quality properties should also include total dissolved substances and e.g. concentrations of chloride and sodium.

Helsingin lämpösaareke ajallisena ja paikallisena ilmiönä

The urban heat island phenomenon is the most well-known all-year-round urban climate phenomenon. It occurs in summer during the daytime due to the short-wave radiation from the sun and in wintertime, through anthropogenic heat production. In summertime, the properties of the fabric of city buildings determine how much energy is stored, conducted and transmitted through the material. During night-time, when there is no incoming short-wave radiation, all fabrics of the city release the energy in form of heat back to the urban atmosphere. In wintertime anthropogenic heating of buildings and traffic deliver energy into the urban atmosphere. The initial focus of Helsinki urban heat island was on the description of the intensity of the urban heat island (Fogelberg 1973, Alestalo 1975). In this project our goal was to carry out as many measurements as possible over a large area of Helsinki to give a long term estimate of the Helsinki urban heat island. Helsinki is a city with 550 000 inhabitants and located on the north shore of Finnish Bay of the Baltic Sea. Initially, comparison studies against long-term weather station records showed that our regular, but weekly, sampling of observations adequately describe the Helsinki urban heat island. The project covered an entire seasonal cycle over the 12 months from July 2009 to June 2010. The measurements were conducted using a moving platform following microclimatological traditions. Tuesday was selected as the measuring day because it was the only weekday during the one year time span without any public holidays. Once a week, two set of measurements, in total 104, were conducted in the heterogeneous temperature conditions of Helsinki city centre. In the more homogeneous suburban areas, one set of measurements was taken every second week, to give a total of 52.The first set of measurements took place before noon, and the second 12 hours, just prior to midnight. Helsinki Kaisaniemi weather station was chosen as the reference station. This weather station is located in a large park in the city centre of Helsinki. Along the measurement route, 336 fixed points were established, and the monthly air temperature differences to Kaisaniemi were calculated to produce monthly and annual maps. The monthly air temperature differences were interpolated 21.1 km by 18.1 km horizontal grid with 100 metre resolution residual kriging method. The following independent variables for the kriging interpolation method were used: topographical height, portion of sea area, portion of trees, fraction of built-up and not built-up area, volumes of buildings, and population density. The annual mean air temperature difference gives the best representation of the Helsinki urban heat island effect- Due to natural variability of weather conditions during the measurement campaign care must be taken when interpretation the results for the monthly values. The main results of this urban heat island research project are: a) The city centre of Helsinki is warmer than its surroundings, both on a monthly main basis, and for the annual mean, however, there are only a few grid points, 46 out of 38 191, which display a temperature difference of more than 1K. b) If the monthly spatial variation is air temperature differences is small, then usually the temperature difference between the city and the surroundings is also small. c) Isolated large buildings and suburban centres create their own individual heat island. d) The topographical influence on air temperature can generally be neglected for the monthly mean, but can be strong under certain weather conditions.

The research goal is to describe curriculas and leadership in day-care centers. The day-care centers needed to write their own curriculas, when Centre for Research and Development of Welfare and Health published The National Curriculum Guidelines on Early Childhood Education and Care in Finland (ECEC) in 2003. The study tries to review day-care center managers views of day-care centers plans for early childhood education and care in three municipals. The research data was collected in the begining of 2008. In previous researches it was found out that co-operation and employees knowledge of education in day-care centers will define the reality (Nivala). Furthermore sosial reality will be based on discussions (Berger JA Luckmann). The subject was approached by one-way analysis of variance. Views of the day-care center managers was compared to the written plans for early childhood education, it s effect on day-care center s early childhood education and evaluation. Besides day-care center managers views were compared to early childhood education. Day care center manager s (N=40) answers were collected to a questionnaire, where there were mainly structured and some open end questions. Data was analysed with PASW Statistics 17 program. The research results showed that the day-care center managers views of the prosess of writing the plans for early childhood education in the day-care centers varied from each other. In addition there were differences in views how the plan of day-care center s early childhood education effected daily in their early childhood education. Furthermore the results showed that there were differenties in evaluating day-care center s education. Whereas the views of early childhood education were not different between the day-care managers in the three municipals.

Elämää keskustassa ja kaupunkiseudun reunoilla. Urbaani ja jälkiesikaupungillinen elämäntyyli asumisen valinnoissa ja arkiliikkumisessa Helsingin seudulla.

The lifestyles of people living in single-family housing areas on the outskirts of the Greater Helsinki Region (GHR) are different from those living in inner city area. The urban structure of the GHR is concentrated in the capital on the one hand, and spread out across the outskirts on the other. Socioeconomic spatial divisions are evident as well-paid and educated residents move to the inner city or the single-family house dominated suburban neighbourhoods depending on their housing preferences and life situations. The following thesis explores how these lifestyles have emerged through the housing choices and daily mobility of the residents living in the new single-family housing areas on the outskirts of the GHR and the inner city. The study shows that, when it comes to lifestyles, residents on the outskirts of the region have different housing preferences and daily mobility patterns when compared with their inner city counterparts. Based on five different case study areas my results show that these differences are related to residents values, preferences and attitudes towards the neighbourhood, on the one hand, and limited by urban structure on the other. This also confirms earlier theoretical analyses and findings from the GHR. Residents who moved to the outskirts of Greater Helsinki Region and the apartment buildings of the inner city were similar in the basic elements of their housing preferences: they sought a safe and peaceful neighbourhood close to the natural environment. However, where housing choices, daily mobility and activities vary different lifestyles develop in both the outskirts and the inner city. More specifically, lifestyles in the city apartment blocks were inherently urban. Liveliness and highest order facilities were appreciated and daily mobility patterns were supported by diverse modes of transportation for the purposes of work, shopping and leisure time. On the outskirts, by contrast, lifestyles were largely post-suburban and child-friendliness appreciated. Due to the heterachical urban structure, daily mobility was more car-dependent since work, shopping and free time activities of the residents are more spread around the region. The urban structure frames the daily mobility on the outskirts of the region, but this is not to say that short local trips replace longer regional ones. This comparative case study was carried out in the single-family housing areas of Sundsberg in Kirkkonummi, Landbo in Helsinki and Ylästö in Vantaa, as well as in the inner city apartment building areas of Punavuori and Katajanokka in Helsinki. The data is comprised of residential surveys, interviews, and statistics and GIS data sets that illustrate regional daily mobility, socio-economic structure and vis-à-vis housing stock.
