Sustainable Water Supply Model in Ambon Island

Abstract

Land-use changes from forest to other use will affect watershed hydrological system that lead to water availability in Leitimur Peninsula watershed, Ambon Island. It aims to analyze sustainability index and sensitive attribute of watershed management and to design watershed management model in supporting sustainability of water resources in Leitimur Peninsula. The analysis applies the Multidimensional Scaling (MDS) model and the dynamic model (Stella). The findings signifies that multidimensional sustainability status is 50.97% indicating quite sustainable, while the best management model is by performing land and forest rehabilitation (LFR) and agricultural extensification through agro-forestry system.

Institutional System of Watershed Management in Leitimor Peninsula, Ambon Island (Watershed Management Institution in Ambon Island Peninsula Leitimor)

“…All parties, both the government-private institutions and society (individual alone or group) are concerned to the watershed management and utilization with different goals. The broader and more varied resources existing in a watershed, there will be more parties who are interested in the watershed (Putuhena et al, 2014).…”

“…On the contrary, natural ecosystem limits are under-utilized, although natural disasters like flood and landslide do not care about political boundaries. Consequently, watershed problem solving does not work when the activities are conducted in apart under respective regional policy (Putuhena, 2014). Generated Revenue escalation.…”
