Water right
• 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

User composition shifting
This has already occured at
Brantas and Citarum Rivers:
• Domestic demands increase
• Industry demands increase
• Agriculture allocation decrease
Water shifts from agriculture

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
Wahana Lingkungan Hidup Indonesia www.walhi.or.id
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
