Brief Summary

This study investigates the impact of school-based educational interventions on adolescents' knowledge and practices related to environmental health in Karachi, Pakistan. The methodology opted for this research is quasi experiment with three months intervention period. The research will begin with a baseline survey to assess adolescents' understanding of environmental health, green spaces, waste management, and associated health impacts. Schools are then engaged in creating and maintaining green spaces and adopting waste management practices. Two intervention arms are implemented: Arm 1 receives educational content through posters, while Arm 2 receives pamphlets. In March, schools are revisited to evaluate the maintenance of cleanliness and green spaces. Finally, in April, a post-intervention survey will be conducted to measure changes in knowledge and eco-friendly practices. The study aims to determine the effectiveness of posters versus pamphlets in enhancing knowledge and sustaining environmental practices among adolescents, thereby contributing to evidence-based strategies for promoting environmental health education in urban school settings.
