Perhaps you should try some spelling variations:
developpement de » developpement des, developpement durable
au developpement » du developpement, de developpement, le developpement
via information » a information, data information, 2 information
technology via » technology vi, technology 4ir, technology vt
de afrique » de l'afrique, en afrique, l afrique
3.0 1 » 5.0 1, 2.0 1
a au » a auf, a bau, a aus

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "technology via information ((3.0 1) OR (3.0 _)) risk communication a au developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology via information ((3.0 1) OR (3.0 _)) risk communication a au developpement de afrique.*.
