The practice consists of mass events that are carried out in collaboration with organizations of the migrant population on topics of entrepreneurship and artistic, cultural and sports exchange. The practice is the “Celebrate Cultures Fair”, financed by the Office of Population, Refugees and Migration of the Department of State of the United States of America, which was conceived to promote socioeconomic integration, as well as cultural and commercial exchange between the refugee and migrant population and host communities. The target population was the entrepreneurial exhibitors, part of training programs of the IOM and other organizations, and the attendees (general public) at the fairs. The Fairs included 1) Cultural agenda; 2) Gastronomic, cultural and artistic endeavors; 3) Services for refugee and migrant populations and host communities. Two editions of the fair were held, both in Surquillo, Lima-Peru, in collaboration with the District Municipality of Surquillo. The first in October 2022 and had the participation of 56 businesses and attendance was 530 people. The second was held in November 2022 and hosted 70 ventures and 395 people attended. Based on this experience, we have sought to integrate mass events with programs implemented for several months. Another important activity within this practice was the Gymkhana for integration, financed by KOICA, which aimed to promote spaces for positive interaction and the work of grassroots social organizations of the migrant population aimed at children, adolescents, young people, adults and families of the Venezuelan refugee and migrant population and the host community of Metropolitan Lima. The Gymkhana was held on December 16, 2023 and included cultural and sports activities, medical and dental care, and immigration regularization implemented by organizations part of the IOM Organized Voices program. 238 people attended.
