Waste refers to discarded materials that are no longer useful. If not properly managed, waste can have significant negative impacts on the environment. Dili, as the capital city of Timor-Leste, has a population of 277,488, accounting for 26.9% of the country’s total population. The high volume of waste generated daily by the population contributes significantly to pollution. With support from the Youth Climate Justice Fund, G-SIG employs GIS tools and the Ushahidi platform to map and monitor waste disposal sites across the municipality of Dili. This initiative aims to support the government and key decision-makers in developing effective waste management strategies while also raising public awareness on proper waste disposal practices. This project is open to public participation.
