International Day of Peace

In celebration of International Day of Peace, Sister Cities International hosted an International Peace Day +SocialGood Google Hangout surrounding this year’s theme, “Partnerships for Peace – Dignity for All” on Monday, September 21, 2015.

Sister city partnerships and citizen diplomacy play a crucial role in peace-building at a grass roots, person-to-person level. Speakers discussed what it means to be a peace-builder and how cities and their people can utilize citizen diplomacy as a tool to not only lessen the chance of new conflicts, but to connect with people of other cultures to build enduring peaceful partnerships based on mutual respect, understanding, and cooperation.

Global Diaspora Week: Digital Diaspora +SocialGood

As part of 2015 Global Diaspora Week, Sister Cities International hosted a Digital Diaspora+SocialGood Google Hangout to highlight the leading cities whose sister city relationships formed or have been strengthened because of local diaspora. Furthermore, panelists discussed how these communities leverage technology and digital media to stay connected and why these tools are important to strengthening and maintaining global relationships.  

Sister city partnerships may form for a variety of reasons including preexisting trade relationships, historical connections, shared geographic traits, and personal experiences ranging from study abroad to marriages. One notable reason that many sister city partnerships are developed is because the local diaspora population takes an avid interest in connecting their new home with their old home. The role these local diaspora populations play in bringing a better understanding of their home culture abroad to their new homes creates a much better understanding overall between the two communities. These relationships help to create more global acceptance and digital technology helps create a platform for easier exchange. During Digital Diaspora +SocialGood, speakers examined diaspora populations’ effect and significance to sister city relationships and how individuals within a diaspora population communicate digitally between their communities.
