This E-Book focuses on "Private-public strategies for sustainable regional development" to facilitate a transformation to sustainable societies on regional geographic scales. The main research questions driving the conference were as follows: "Why Strategies for Sustainable Regional Development?" and, "Can collaborative strategies by multi-stakeholders facilitate the conditions towards sustainable regional development models?" Business, commerce and industry operate in increasingly global settings. Sustainable development is also closely connected to global systemic changes, and regional settings demands additional attention for efficient operation of private-public strategies implementation. Furthermore, due to the interconnection between sustainable production and consumption patterns, collaboration among all the parties involved is currently seen as an important success factor. Consequently, business, governments, citizens and NGOs need to meet at the regional level and interact. During the 3rd GIN conference in Mexico City, stakeholders from those sectors participated by sharing their experiences and visions about "sustainable regional development".
