Results & Impacts

A Summary of the overall results & impacts to date (Sept 2015)

The main results so far:

  • Since the start of the program, 1,500 sites have been built by NV masons and entrepreneurs, for 20,000 direct beneficiaries, in 700 locations (villages, hamlets, towns) in 6 countries of the Sahel (Burkina Faso, Mali, Senegal, Benin, Ghana and Mauritania)
  • Total vaults production reached 68,000 sqm of usable area built.
  • 87% of NV buildings are houses, and 13% are for community use (churches, mosques, community centers, schools...)
  • 380 NV masons have been trained, of whom half are at the foreman and/or entrepreneur level
  • There are currently over 300 apprentices in training
  • On the last ten years, the program has experienced an average annual growth rate of 31%.


And we estimate the impacts of the Program as being:

  • 20,000 people use, live in, or sleep in NV buildings;
  • 33,000 corrugated iron roofing sheets have been economized
  • 55,000 tons of CO2-equivalent economized,  as a result of NV construction, as compared to the alternatives
  • 2 millions Euros of local economic impacts have been generated.


One of the most encouraging outcomes is that over one-third of the NV construction market is now completely autonomous and self-sustaining: 17% of NV clients are found directly by NV builders / entrepreneurs. Of the remainder, 30% come via a local intermediary or ’champion’, 32% via AVN itself, and 14% via AVN's partners. So, in the regions where AVN is active, we are well on the way to a growing and independent market in NV construction, permitting us to soon move on and target our resources in new regions.
