I am sorry I must respond in English. I do not speak Spanish. I was able to get your question translated.
I am not aware of any place that has solved the problem you described. Such problems often have local origins and are best solved by looking at what contributes to or causes the problem.
I suggest you begin by examining what is leading to this problem. The Community Tool Box Chapters 17-19 provide guidance for analyzing the problem and then designing a solution that addresses the causes you uncover within your community. Then Chapter 5 presents guidance for choosing strategies. If you need to get local government to pay attention. Chapter 4 provides guidance for getting the issues on the public agenda.
I am sorry I could not provide a more definitely solution for you, and sorry that this is written in English. I hope the information is helpful to you.
