At the 2025 Stockholm Water Week the GOPA MetaMeta / SMART Centre Group presented the new “Portable solar pump” that was developed in the last 5 years by the Jacana SMART Centre in Zambia based on input of farmers. It can pump 5 – 15 cubic meters per day and in Zambia is sold now at around $220.
We also presented about “supported self-supply” in the session “Restoring landscapes through innovative finance” together with TIARA -SIWI, Tiyeni and IRHA. With examples it was shown that SDG6.1 basic service in Africa is possible at a one-time support of $25/ person in areas with >200 mm rainfall / year.
The supported self-supply model consists of:
- Use innovative low-cost technologies,
- Focus on family-owned farm wells who share water with neighbors
- Productive uses so income generation to pay for pump maintenance
