ACCRA FORUM

5th RWSN Forum 2006 – GhanaScaling up Local Entrepreneurship in Rural

Water Supply to meet the MDGs

Date : 27th - 30th November 2006Venue: Royal Palm Hotel, Accra,

Ghana • Around 200 participants from Africa, Asia and

Europe.• Field visits prior to main forum 24-26th

• To encourage stakeholders to consider alternative approaches to rural water supply

• To build on the research undertaken through RWSN, as well as experiences from other organisations and communities,

• To provide a platform for extensive dialogue and demonstration (50% of programme)

• To provide feedback to the RWSN core team regarding future focus and linkages for the network.

RWSN THEMES

EXISTING RWS STRATEGY

Self supply sustainability

• Technologies are as far as possible replicable • Phased and affordable improvements in supply, with

minimum design standards• Local entrepreneurs provide safe water supplies and

easier water-lifting devices and promote low-cost options.

• Linkage is made to economic and nutritional benefits, increasing the perceived value of water supply.

• Ownership and management are maintained within naturally developed groups and empowered to make choices and solve problems mainly at own cost.

• An enabling policy environment, combined with low cost and high proportion of private investment, allows rapid advance for large numbers of people,.

Where are we starting from?

Mali 48% domestic wells used for productive purposes, 85% of these are privately owned.

LINKS TO PRODUCTIVE USE

Positive Negative

Sustainability/ Affordability

Pressure to over-use supply

Sustainability/ value Exclusion?

Water quality improvement with increased turnover

Returning leachates from cultivation

Increased promotion/ market for technologies

Promotion of good nutrition and irrigation practice

Linkage to support networks of health and agriculture

COMMON GROUND WITH PRODWAT

• Promotion of family level investment• Development of /support to low cost technologies

(spares, maintenance services, stocks, manufacture)

• Improved knowledge of resources• Promoting the linkage of domestic supplies and

livelihoods.• Aiming for several MDGs

So how could we link up better?
