Global Water Security Challenge – Collaborative Actions for Sustaining a Common Property

Global Challenges and Pressures

•768 million people lack access to improved WS

•2.5 billion people lack basic sanitation (70% in Asia)

•1 billion people practice open defecation (70% in SA)

•3.4 million people die/y from water-related disease

•2 million tons/d of sewage, industrial, agricultural

waste are discharged into the world’s water

•Depleting groundwater - land subsidence

•Climate change - Increase of extreme weather events, floods/droughts

•Nitrogen, pesticides, endocrine disruptors

A Defining Moment in Time

Post-2015 and Water

Lobby for an SDG for Water responding to three

objectives:

1. Achieve universal access to sustainable sanitation and

to drinking water that is really safe

2. Increase wastewater management and pollution

prevention

3. Improve water security through integrated water

resources management and water-use efficiency

WATER SECURITY is defined as the capacity of a population to safeguard access to adequate quantities of water of acceptable quality for sustaining human and ecosystem health on a watershed basis, and to ensure efficient protection of life and property against water related hazards -- floods, landslides, land subsidence,) and droughts.

Future for Urban/Peri-Urban Areas

• Urban Water Solutions Development of ASPAC

Flagship programme towards sustainable and

effective water management in ‘The City of the

future’

Develop and deliver strategy for transformational

change:

• A holistic approach

• Reduce water use (all uses)

• Reuse water (water chain)

• Help water (eco-)systems cope
