Latuppa stream, the most potential water supply to PDAM Palopo and irrigation to agricultural land, hasserious environmental degradation due to behavioural factors of local inhabitants in watershed area of Latuppa whocontinuously exploit forest area to produce woods, housing, and plantation. Those contribute to flood and landslide inrainy season and extreme dryness in dry season in Palopo.
