Greetings to all. Here are my contributions to the last two initial questions. I did not have time to ponder on the follow-up questions. I hope this e-dialogue yielded the results that were hoped for.
1. I believe that creating a system of incentives (e.g permits to sell in areas where there are more potential customers, such as near schools, hospitals, transportation hubs; vouchers or some sort of recognition mechanism for good practices) is required for motivating the street vendors to use locally-sourced, fresh produce. Do you think that such incentives could be successful, and why? What other types of incentives might be, and why?
Recognition will only go so far. I suspect pricing, convenience and perceived quality are the major issues.
2. What new mechanisms can be put in place to raise peoples’ awareness on the consequences of their street eating habits? Do you know any advertising methods, which have been proven effective?
I am not aware of any advertising methods nor whether such methods have been effective or not. I suspect the most issues are price, convenience and quality, as above.
However, the above answers are based on conjecture rather than systematic evidence.
