Supra-regional strategies are created for two or more voivodships, which are bound not only by geographical neighborhood, but also by common goals and development challenges. The legal basis for developing supra-regional strategies is the Act of 6 December 2006 on the principles of conducting development policy. These strategies arise mainly from the willingness to cooperate between the authorities of individual voivodships. The minister responsible for regional development, in consultation with self-government authorities and social and economic partners, is responsible for the final preparation of the draft strategy.
Individual strategies were adopted by relevant resolutions of the Council of Ministers. Those are:
- The Strategy of socio-economic development of Eastern Poland until 2020, adopted on 30 December 2008 and updated on 11 July 2013; the strategy realization area covers 5 voivodships: Lubelskie, Podkarpackie, Podlasie, Świętokrzyskie and Warmińsko-Mazurskie;
- The Development Strategy of Southern Poland until 2020, adopted on 8 January 2014; the strategy realization area covers 2 voivodships: Małopolskie and Śląskie;
- The Development Strategy of Western Poland until 2020, adopted on 30 April 2014; the strategy realization area covers 5 voivodships: Dolnośląskie, Lubuskie, Opolskie, Wielkopolskie and Zachodniopomorskie;
- The Development Strategy of Central Poland until 2020 with the 2030 horizon, adopted on 14 July 2015; the strategy realization area covers 2 voivodships: Łódzkie and Mazowieckie.
