Elisabeth Muyinganyiki, a 19-year-old Rwandan child rights, gender justice, and environmental activist, demonstrates the transformative impact of investing in children's meaningful participation. She joined Children's Voice Today (CVT) grassroots groups at age 13 and became actively engaged in its programs by age 15. Through CVT's training, mentorship, coaching, and leadership opportunities, Elisabeth developed strong skills in child rights advocacy, leadership, public speaking, and civic engagement. She progressed from a grassroots group member to a confident youth leader and advocate influencing discussions on children's rights, climate justice, and youth participation at local, regional, and international levels.
