Launch Workshop
“Open-source mobile weather stations:
reducing flood damages and increasing the preparedness of communities”
IWMI, Sri Lanka,
3 May, 2016
IWMI’s vision - A water-secure world
IWMI’s mission - To provide evidence-based solutions to
sustainably manage water and land resources for food security, people’s livelihoods and the environment
Water Futures vision – A decision support toolkit that helps
planners, managers and stakeholders understand and assess possible futures and sets of solutions.
Mission - To identify contextually-appropriate pathways to achieving
sustainable water security.
Half our planet’s population are water insecure… uncertain futures
Absent or unreliable WSS Food security and Irrigation
The impacts of unmitigated variability including floods & droughts Degraded water environments

• Water use grows with income.
• GDP/capita rises everywhere, while GDP in China could start to decrease in the latter half of the century.
