Italy has social work opportunities all over the place, but the southern region is in need of the most help from those wanting to volunteer abroad. The economic difference between the north and south of the country is a consequence of strong industrial development of the northern region while the southern region remained agricultural. With just a few hours of work each day on a project or with an NGO, you get free accommodation while help those in need.
To be a part of volunteer work in Europe, the main requirement is to have a willingness to help. With volunteering, besides getting to see the beautiful sights of Italy, you exchange a few hours of your day for accommodation and share your knowledge with those who need it. Doing exchange projects this way are full circle because they are more economical, allow you to see a new country, and bring a lot of learning along with solidarity.
