Water and Poverty
1 billion lack access
to safe water
 2.6 billion are without
basic sanitation

The MDGs


On track: Water supply
Off track: Sanitation
• >500 million people will be missed

Beyond the pipes
• Good policies, accountable
and capable institutions required
Urbanization

The urban shift and growth of slums
has major implications on water
infrastructure development

Impact on Infrastructure




Damage from coastal flooding,
glacier melt, hurricanes
Salt water intrusion into aquifers and
lower flows from glaciers reduce
drinking water supplies
Need for more water storage,
wetlands loss
Overexploitation of aquifers
Glaciers in the Andes (Colombia, Ecuador, Peru, Bolivia,
Chile, Argentina) have lost volume
Photos of the Qori Kalis
Argentina's Upsala Glacier, once the biggest in South
America, is now disappearing at a rate of 200 meters
per year
A temperature increase of 4o C is anticipated to
lead to a collapse of the Amazon Rainforest
Ecosystem (Brazil, Colombia, Bolivia)
Most Important Effects in LAC





Glacier Melt
Coral Bleaching in the Caribbean
Increased Hurricane Frequency
and Intensity
Collapse of Tropical Rainforest
Coastal Flooding
Economic impact from climate change in
LAC by 2050





Combined impact of sea level rise, loss of
fisheries and tourism calculated to equal 530% of GDP in the Caribbean
Water supply to cities will be affected (Quito
may see water supply costs increase by 30%,
La Paz, Lima, Bogotá also to be affected by
diminished supplies caused by climate
change)
Power generation will be more expensive as it
shifts from hydro to thermal
Health costs will be affected by increased
exposure to tropical diseases
The cost of hurricane impact has increased by
two orders of magnitude in the Caribbean
basin in the last 20 years and hurricane
intensity is expected to continue increasing

Investments in Water
Water investments provide multiple
co-benefits and are drivers of growth and
poverty alleviation.
• Health
• Environment
• Building government
track record
• Education
• Gender equality
• Economic growth

A minimum platform for infrastructure and
institutions is needed to move along the
path of sustainable development.

Investments in Water
The S-Curve
Considerations of Climate Change

Challenges for developing countries
• Needs for additional water infrastructure
and nonstructural investments
• Adaptive management to address
uncertainty about implications of climate
variability and long term impacts on the
water balance
Adapting to Climate Change



Augment Supply:
•
•
•
•
•
Expand alternatives of water supply and storage
Increase efficiency of water supply services
Control water balance at basin level
Sustainable aquifer management (recharge)
Desalination
•
•
•
•
Foster water quality management at basin level
Phased approach to investments and standards
Support priority investments in wastewater treatment
Support reuse
Pollution Management:
Water Consumption
• Economic incentives to reduce consumption and waste
• Support R&D on cutting edge water technologies and
reuse
• Increase productivity of water in irrigation systems

Support efficiency and sustainability
of water investments




Charge the well-to-do, subsidize the poor
• From (regressive) consumption subsidies to
connection subsidies for the poor
• Public Expenditure Reviews to inform public
financing policy
Apply smart technology
• Focus on system improvement before expanding
capacity
• Flexible standards decrease cost
• New irrigation and drainage techniques, reuse,
desalination
• Better designs of dams
Secure O&M
• Revenues from consumers, as a minimum, should
cover O&M to underpin sustainability
‘Climate proof’ new investment
• The infrastructure that is built now, will be subject
to increasing variability and climatic uncertainty

Regional Examples of Corruption
In Africa
•80 percent of urban
water utilities in
Africa are considered
financially unviable
In 21 water companies
in Africa, nearly twothirds of operating costs
were due to corruption
Cross, Piers. WSP. 2007.
Estache & Kouassi. 2002
In South Asia
• False readings: 41% of
customers had paid a bribe
in last 6 months
• Illegal connections: 20%
of households admitted
paying a bribe to utility
staff
• Contractors: 15%
excess cost because of
collusion
• Kickbacks: 6-11% of
contracts value
Cross, Piers. WSP. 2007.

much further than PSP
It is estimated that of

consumers
• 41% enjoy regulatory
protection
• 15% are supplied by a
