Presented by IWMI's Director General, Claudia Sadoff, at the 3rd Karachi International Water Conference in Mövenpick Hotel, Karachi, Pakistan, on November 22, 2017.

4. 25% more people by 2050 in Asia
Domestic water demand to triple
& industrial to double by 2050
By 2050, 40% of Asia’s population
in severe water scarcity
Growing population – growing scarcity
5. Asia among fastest growing economies
Among the fastest urbanizing
Over 22 megacities in Asia by 2030
Shifting demands sectorally & spatially
Economic transformation & urbanization

6. Sharing “closed/closing” river basins
Roughly half of the basins in Asia are
transboundary
Many ‘closed’ of ‘closing’, meaning that all
water is used (includes environmental flows)
Increasing demands, increasing tensions
Sub-optimal management & development
7. Climate variability & uncertainty
Schew et al. (2013)
Relative change in annual discharge at 2oC vis. today, under RCP8.5
• Wet gets wetter – Dry gets drier
• Per capita water declines in much of Asia
• In South Asia up to -30% per capita
• More extremes, double the drought days
• Variability well outside the historical range
Little aggregate volume change projected – however:
11. Intensify sustainable agriculture
Sustainable agricultural intensification potential
• Largely in rainfed agriculture
Water smart agriculture for smallholders in Asia
Better methods to capture, store & conserve water
• Small-scale irrigation systems
• Participatory groundwater management
• ‘Green’ solutions i.e., rainwater harvesting, watershed
management
Water productivity innovations
12. Resource Recovery
and Reuse Business
Models
Wastewater recycling – ‘water portfolio’
Remove hazards from the environment
Return resources - water, nutrients
and energy – to productive uses
• Groundwater recharge
• Industrial & landscape water
• Salt-water intrusion barrier wells
• Fertilizer pellets from sludge
• Energy from biogas
13. Manage uncertainty & enhance resilience
• Forecast & early warning of drought/flood
• Last mile connectivity – apps, etc.
• Enhanced storage capacity and more
coordinated management of storage
• Redundancy in supply
• Index-based weather & crop insurance to
reduce economic impacts of shocks
Remotely sensed drought monitoring
15. Water policy can promote inclusion
Institutional and policy measures that offer
inclusive access to water, with special
emphasis on gender equality
Sustainably managed solar irrigation –
strengthens ‘agency’ by de-linking from
publicly provided water & energy
16. Technologies to inform water policy & mgmt
From small-scale, ground-based, citizen
science like mobile weather stations…

18. …to web-based information systems, decision
support systems, geo-spatial tools, and
platforms for options analysis
