Wikipedia's description of 'Gleaning' is the collection of leftover crops from farmers' fields after they have been mechanically harvested or on fields where it is not economically profitable to harvest.
"Glean The Planet is a community resource to facilitate the sharing of food. Gleaning is about sharing food resources that would otherwise go to waste. Whether you are looking for free vegetables or have an apple tree you don't have time to pick from, you can use GTP forums to spread the word."
The project intersects with recent public debate in Copenhagen about air pollution in the city. In collaboration with Senior Scientist Jørgen Brandt from The National Environmental Research Institute in Denmark a first prototype is developed for making an indicator that can be placed in the city and display local levels of pollution as well as pollution forecasts on individual streets. The project holds an open source script for displaying data from the Internet in a variety of forms.
