In September and October 2015 MDI studied the regional cooperation model of Kemijärvi, Salla, Savukoski and Pelkosenniemi municipalities. MDI studied how the regional cooperation could be executed in a more flexible and economical way. The options are further developing the current organisational model, a registrated association, company model or functioning without a separate organisation, for example as a cooperation group of municipal leaders. The work took into account special circumstances and future possibilities and arising needs for cooperation in Eastern Lapland.
