Sustainable development project for the construction of Peace coordinated by SCI-Catalunya and realized under Adela has been a project of permaculture and social transformation where the voluntarily was integrated in the local community and lived for six months in cooperation with members association of alternative local development. It was an entire project where the vast majority of hours per day with other people and shared many environmental and sustainable development activities, social transformation and peace was made. This system permit the voluntary fully integrated into volunteering and to know the culture, traditions and way of life of the community where he lived and local, apart from progress and have an inner change. We believe that the project also provided an invaluable benefit to the local community and the association received new information, new prespectives and different ways of acting in an active international volunteer as we proposed. Sharing, continuous learning and cooperation, both sides did evolve and have beneficial results by the volunteer and also by the association. We can see that the draft tube positive results and that affected a high number of youth groups and thanks to the benefits. That's why we also propose a dynamic long time, establishing a network between voluntary, partnership and other participants such as CO and SO. We believe that the only way the project could be a model and with good results for all.
