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. The applied accessibility methodology has been developed in Finnish regional case and successfully tested in European scale. The study focuses first to establish the analysis in Africa, India and China – where population dynamics are intense. After testing and validation of the methodology to the study regions, the analysis is extended to global scale. The project can plausible be executed thanks to rapid development in open source geospatial big data and its applicability in Geographic Information Systems (GIS)-based analyses. Analysis includes distribution of population, food resources and transports at the same time. Two year project is funded by Kone Foundation.

Quantification and valuation of ecosystem services to optimize sustainable re-use for low-productive drained peatlands (LIFEPeatLandUse)

Aim is to produce GIS based maps to demonstrate the predicted impacts of peatland re-use options on ecosystem services within project LIFEPeatLandUse. The main objective of the LIFEPeatLandUse is to quantify and valuate ecosystem services to assist land use planners and policymakers in making ecologically, economically and socio-culturally sustainable land use decisions. This is done by developing and demonstrating a decision support system, where ecological and economical information is aggregated to numerically optimize cost efficient land use options so that benefits from ecosystem services are safeguarded. The monetary value of the land use options is maximized under given constraints set to the biodiversity, environmental loading, and GHG emissions, to fulfil the constraints set in the regional, national, and EU level policies. The system is tested and demonstrated to optimize the re-use for low-productive drained peatlands, which is the key issue concerning peatland use in Finland. Funded by LIFE+ Environment Policy and Governance (LIFEPeatLandUse).

Balancing Local Politics, Housing Preferences and Sustainability in the New Detached Housing Areas in the Rural-Urban Interaction Zones (BALANCE)

GIS based analysis of university graduates was included to the final stage of BALANCE-project, and results of this analysis are aimed to be publised during year 2017. The general aim of the BALANCE study was to find balancing and reconciliative approaches to local politics, housing preferences and sustainability in the context of housing and land use in the new detached housing areas (new villages) in the rural-urban interaction zone. The geography reserach unit's sub-project considered development paths in different new villages in the context of housing preferences, and more precicely how have the positive and/or negative development paths of different urban regions effected to the housing preferences of inhabitants in the new villages? The GIS based analyses focused to reveal migration patterns of skilled labour in relation to regional competitiveness.

Liikuntapaikkojen saavutettavuusindeksi (LINDA) / Accessibility of sports facilities

Liikuntapaikkojen saavutettavuusindeksi (LINDA) -hankkeessa kehitettiin liikuntapaikkojen saavutettavuuden paikkatietoperusteinen mittaustapa. Saavutettavuustarkastelua voidaan hyödyntää liikunnan olosuhdepolitiikan seurantavälineenä ja tuoda esiin kuntien liikuntapalvelujen saavutettavuuden taso ja sen alueelliset erot. Saavutettavuustarkastelut toteutettiin paikkatietojärjestelmässä hyödyntäen LIPAS-tietojärjestelmän liikuntapaikkojen paikkatietoja, yhdyskuntarakenteen seurantajärjestelmän YKR-väestöruututietoja ja Digiroad-liikenneverkon mallia. Työ toteutettiin Oulun yliopiston maantieteen tutkimusyksikössä vuosina 2014–2016. Päävastuullisena tutkijana toimi Ossi Kotavaara (FT) ja työtä ohjasi Jarmo Rusanen (professori) sekä Risto Järvelä (rakennusneuvos) Opetus- ja kulttuuriministeriöstä. Hanke on toteutettu Opetus- ja kulttuuriministeriön rahoitustuella.

Terveet tukipalvelut - Tehokkaat ja käyttäjälähtöisen tukipalvelumallit pitkien etäisyyksien terveyspalvelujärjestelmissä / Healthy Suport ServicesTerveet tukipalvelut -hankeessa on tutkittu terveydenhuollon logistisia tukipalveluja Oulun yliopiston Kauppakorkeakoulun,Tuotantotalouden yksikön ja Maantieteen tutkimusyksikön yhteistyössä. Maantieteen työpaketissa kehitettiin paikkatietoperusteisia jakeluverkostojen ja varastojen fyysisen sijainnin optimointiin soveltuvia menetelmiä. Tiestön ja terveyspalvelujen sijaintitietoihin perustuen Pohjois-Suomen kokoisen alueen logistiset tukipalvelut voidaan tuottaa 1-2 palvelukeskuksen avulla. Hanketta on rahoittanut TEKESin Innovaatiot sosiaali- ja terveyspalveluissa -ohjelma. Lisää aiheesta

Sosiaali- ja terveyspalveluiden palveluverkko 2025 / Social and health service network 2025

Hankkeen tavoitteena oli arvioida sosiaali- ja terveyspalveluiden perus- ja erikoispalveluiden maantieteellistä saavutettavuutta ja palveluverkon alueellisia muutostarpeita vuoteen 2025 mennessä. Muutostarpeita arvioitiin suhteessa väestökehitykseen, ikärakenteeseen sekä uusien digitaalisten palveluiden ja sote-palveluiden maantieteellisen uudelleenorganisoinnin mukanaan tuomiin mahdollisuuksiin. Hanketta rahoitti Sitra.

RuokaGIS

Local and organic foods have gained a larger share of the markets in Finland during the last years. Potentials to increase the use of local food have strong connections to accessibility. The RuokaGIS project will use geospatial analysis and geographical information systems/science (GIScience) to reveal location and accessibility patterns of local and organic food at the province of Northern Ostrobothnia, Finland.
