LACK OF CORRELATION BETWEEN GDP GROWTH
AND ACCESS TO IMPROVED WATER SOURCES
• High Population Growth
• Possible lack of inclusiveness in the recent GDP growth in Africa. – Largely Commodity price-driven GDP
Growth.

WATER AND SANITATION
High Correlation between the two Sectors.
Access to Sanitation lagging behind Access to Improved Water.
High Correlation between income and Access Rates.
• Service/management contract
–Relatively common in WSS in Africa.
– Can lead to Improvements in quality of services.
– Increase in access not guaranteed.
• Lease/Concession
–Less common in Africa in WSS in Africa
– Can lead to Improvements in quality of services.
– Increase in access likely.

CHALLENGES FOR PPP:
IMPLICATIONS FOR MDG TARGETS
-Countries with favorable investment climate already have high access rates. Limited Capacity for countries with low access rates. High rate of cancellations in previous PPPs.
