Validation/upscaling
Yes. SDCMR has operated continuously since 1994, and its published institutional figures report several thousand water-harvesting and storage structures (check dams, cisterns, and reservoirs) across the wadi systems of Matrouh Governorate, alongside reclamation works in dozens of wadi valleys. The approach has subsequently been reinforced and partly re-evaluated through two externally funded programmes: IFAD-PRIDE (2019–ongoing, USD 81.6 million, targeting roughly 450,000 people / 60,000 households across the governorate, of whom about 36,000 households are direct beneficiaries) and the EU-PRIMA SALAM-MED project (2022–2025), whose Matrouh Living Lab tested water-harvesting and nature-based solutions specifically in the wadi systems feeding into this practice.
