Here's a link to a write up about the former mayor of Bogota City, Colombia. It also includes how he transformed the city with 'green' innovations that employed the poor and helped the environment. Here's a summary of what he accomplished in his term:
As mayor, Peñalosa:
- Created a successful Urban Land Reform institution.
- Created a new bus-based transit system: TransMilenio.
- Spearheaded large improvements to the city center, including the rejuvenation of plazas, creation of a large park in an area previously overrun by crime and drugs, and transformation of one of the main deteriorating downtown avenues into a dynamic pedestrian pubic space.
- Built more than a hundred nurseries for children under 5 and assured resources for their operation.
- Increased children enrolment in public schools by more than 200,000, a 34% increase in four years; did major improvements to more than 150 school buildings and built 50 new schools.
- Put in place a network of 14,000 computers in all public schools connected to both the Internet and a network of 3 large new libraries and several smaller ones that were built.
- Planted more than 100,000 trees.
-
Built or reconstructed hundreds of kilometers of sidewalks; more than 300 kilometers of bicycle paths, pedestrian streets, and greenways; and more than 1,200 parks.
-
Instituted the city’s first “Car-Free Day” in 2000, for which he received the Stockholm Challenge Award. Through a referendum, people adopted a yearly car free day and decided that from the year 2015 onwards, there would be no cars during rush hours, from 6 AM to 9 AM and from 4:30 PM to 7:30 PM.
