【 摘 要 】

The current water resources management in Indonesia requires the government to pay more attention on sustainable water management. Agriculture as the highest water demand in the country need better water management as the impact of future changing climate. Furthermore, the water managers as well as policy makers may require integrating the climate change assessment into water resources allocation policy and management. Agropolitan in Malang district, East java - Indonesia is an agriculture which is characterized by complex agricultural system and was assigned as a case study. The supply-demand water allocation approach was applied on allocating water to different water users under current and future climatic condition. Both climate and the changing nature of water demand have affected the development and evolution of water allocation. The result shows that the water supply is expected to decrease under future climate comparing with the current condition. Furthermore, it is required to incorporate the future climate information on design the future water policy and management to reduce the adverse impact of changing climate. This study also suggested policy actions as recommendation to better manage current climate variability as well as future uncertainty from climate change impacts on water allocation and resources management.
