People spend most of their lives in buildings, and their design significantly affects economies and lifestyles.

Traditionally, local materials and craftsmanship suited buildings to their environments, but modern construction relies on imported materials like cement and steel, especially in African countries.

Research in Zambia's Green Jobs Programme showed that using local materials boosts local economies and resilience. Locally sourced components reduce carbon emissions, enhance economic diversity, and create jobs.

Although local materials aren't always cheaper, they offer long-term economic benefits. To promote local content, updated regulations, coordinated projects, and professional training are needed.
