An example of a succsesful program in the U.S., is Berkshire County, Mass. Residents there pay $10 to get 11 "BerkShares," which are widely accepted in local stores, encouraging people to shop at home instead of using dollars to buy goods online or at large retail chains. Launched in 2006, BerkShares are still being used.
The idea is that by using local currencies, residents don't spend so many dollars, pounds or euros, keeping more resources within their communities. And because local currencies can't be easily banked or invested to earn interest, users keep spending it, providing a boost to their area's economy.
A wide literature exists to help communities get started in implementing this kind of project. All it takes is committed group of people to get it off the ground, and thats what I'd like to help start. I'll try to disseminate this through various means and gauge interest. Feel free to comment with your own ideas, and lets get started on a proactive local solution to all the financial calamity in the news.
