The most powerful climate solutions aren’t always high-tech and brand new. This one is simple and ancient.
By contributing, you’ll help people living in the Sahel to build houses using a technique that’s thousands of years old – but which reduces carbon emissions and helps families adapt to climate change.
Around 22 million Malians and Burkinabe live in rural areas, and population growth is estimated at nearly 3% per year.
Many households in the Sahel region survive on less than $2 a day and live in tin-roofed buildings that are not suited to the rising temperatures caused by climate change. The wood used to build them is also becoming increasingly scarce.
The Vault technique, which originated in Nubia (now Upper Egypt), involves building houses with vaulted roofs without a timber framework or shuttering; it uses locally sourced raw materials and simple tools, and requires only a basic level of technical competence.
The most ancient mud brick Nubian Vaults, in Luxor, are still standing over 3,300 years after their construction.
The houses also reduce CO2 emissions because they’re made with raw earth instead of metal sheets and cement, and they need less energy to keep them cool once they’re built.
By giving people the financial help to build these bioclimatic houses, the project’s potential impact on climate change is equivalent to 7% of the CO2 emissions produced each year in France by road traffic.
The natural insulating properties of raw earth make these dwellings much more comfortable than those with tin roofs. So the Nubian Vault is a relevant solution for local populations to adapt to climate change – and the only one that is financially accessible to them.
In addition Nubian Vault are:
