Africa (2007 update): Sub-Saharan Africa is not on track to achieve any of the Goals.

7. Ensure environmental sustainability• Integrate the principles of sustainable

developmentinto country policies and programmes.

• Reduce by half the proportion of people without sustainable access to safe drinking water and basic sanitation.

World Summit on Sustainable DevelopmentPlan of implementation (Johannesburg 2002):• Currently between 2 and 3 Billion people without access

to reliable affordable and clean energy• Half this number by the year 2015

HRM prince Willem Alexander During his official visit to India• Currently 1.2 Billion people without

access to clean water

ARRAKIS

Access to clean water is the critical point for the poorest• Little R&D efforts to implement water pumping

windmills• Most R&D efforts in high tech area (45 Fte at TU

Delftin wind energy)

• Development needssupport using AT:

Example: South Africa

• Currently 8 GWh electrical energy produced from wind

• But 26 GWh generated for water pumping purposeswith 23.000 wind pumps (Climax pump Soutern Cross)

Thank you for your attention.

Discussion

• Is the current profile of TU Delft on sustainability not too much focussed on high tech application?

• Should TU Delft extend its profile with affordable technology activities? (“contextuality”)

• If yes, how to enhance sustainable development with affordable technology at TU Delft?(in both research and education)
