The Sustainability Demonstration Center and the Social Solidarity Network are collaborating in Costa Rica to improve the quality of life of all sentient beings through trading.  We have our own unit of exchange called the Guacimo and a trade route called RuTaCom that we are actively expanding to the entire territory and which includes people who produce food and items and people who provide services of all types including dentistry and medicine.

The SDC is also partnering with the Mutual Aid Network our of Madison, Wisconsin.  "Mutual Aid Networks (MANs) are a new type of networked cooperative creating means for everyone to discover and succeed in work they want to do, with the support of their community. Through the HUMANs (Humans United in Mutual Aid Networks, formerly the Main MAN), a global umbrella cooperative, all pilot sites and members share their tools, experiences and resources. Together we demonstrate that the economy is what we make it."  You can read more on their website:  mutualaidnetwork.org
