Introduction
The process of development of the SDWP paid special attention to the supra-regional dimension. Formulation of the intervention directions took into accountthe specific characteristics of the macro-region, which is consistent with the principle of the territorial approach to development, which is based on the assumption that one should make morę efficient use of endogenous resources of different types of territories and build development strategies on them81. Works were also carried out in accordance with the principle of subsidiarity, consisting in selecting the management level of public intervention which is most adequate for the identified development objectives.
The efforts to maximize the developmental effects resulting from the activities provided for in the SDWP led to thematic concentration (selectivity) of areas of support, which is one of the basie principles of designing a strategy document. The SDWP focuses on carefully selected supra-regional issues occurring with particular intensity in the macro-region. Support for these issues will contribute to the greatest extent to achieve the development objectives of Western Poland.
The SDWP is based on the principle of evidence-based policy. Formulation of development objectives and intervention directions to implement them was preceded by a diagnosis of the socio-economic situation in the macro-region, based on the analysis of available studies and identification of key developmental potentials. The vision of development of the macro-region took into account the key challenges and trends that may have most influence on the development processes taking place in the area. Implementation of the SDWP was based on monitoring progress in achieving its objectives and on sound assessment of the effects of actions taken. The condition for effective implementation of the SDWP is the best use of the potential of interregional, cross-border and transnational cooperation to achieve the common objectives of development, hence the strong emphasis on this issue in the entire document.
Opinion of the General Directorfor Environmental Protection on the environmental impact assessment
The SDWP was consulted with the General Directorfor Environmental Protection
(GDEP) in order to determine whether it is necessary to carry out the strategie environmental assessment for the document under the Act of 3 October 2008 on the provision of information on the em/ironment and its protection, public participationinenvironmental protection and environmentalimpactassessments91. On 31 October 2013, the minister in charge of regional development received 81 Potentials Identified in the SDWP arise from the analyses madę, which allowed for distinguishing features common to the area of Western Poland. Situation of a single region is presented in the document only when a given feature in a particular voivodeship is significantly different from the situation in the macro-region (the so-called "outlier").
