Thank you for writing to us at the Community Tool Box with your important question, and please excuse our delay in getting back to you.
Your question is of course very specific, and many details of a response would be unique to Ethiopia. But you can find some general information about social marketing in the Table of Contents of the Community Tool Box, such as in Chapter 45, Section 1, on Understanding Social Marketing, at /en/sustain/social-marketing/overview/main and in other nearby sections in Chapter 45 as well. This might be a useful place for you to start; we hope so.
Many best wishes for success as your important work proceeds.
