• Water right supporter: efficient allocation unit and a solution of water crisis in urban and industry consumers.

• Water right lead allocation based on its economical status settlement, industry (Chile and Srilanka)

• Water Act No.7/2004 : not allowing the origin “water right” concept (ownership/entitlement)

• Regarding water crisis, reallocation of water from agriculture to other sector is inevitable

• This condition threats food security

Other source: Problematic!• Water body (river basin, lake, estuaries, water spring)

- polluted, saline water intrusion, decreasing• Ground water

- un-renewable, subsidence, contaminated (e-coli form)

- North Jakarta reach 35cm subsidized in 10 years• Packed water

- expensive, litter

Solutions and Alternatives• Restoration ecosystem to normalizing hydrology cycle.• Diversification staple food (1 kg rice = 3000 L water)• Develop new planting method to reduce the use of water• Public campaign to raise people awareness of water as

limited resource• Decentralization to facilitate citizen distribution
