Enhancing Tree Planting Programs with a User-Centric Web Portal for Subsistence Farmers

The project aims to develop a web portal enhancing the International Small Group and Tree Planting Program (TIST). By providing a user-friendly interface for quantifiers who assist subsistence farmers in Africa, the portal addresses critical challenges like PDA data downloads and filtering issues. Built on Yii framework in MVC architecture, it incorporates role-based access control for data security. The initiative strengthens communities, fights deforestation, creates jobs, and enhances farming education, ultimately promoting a sustainable future.
