In the Republic of Djibouti (Horn Africa), fractured volcanic aquifers serve as primary water resource. The country’s climatic characteristics (arid climate, average rainfall 140 mm/year, and absence surface water) have led to intensive groundwater exploitation meet increasing demands. This study focuses on Dalha basalts aquifer in Dikhil region. region, located southwest bordering Ethiopia, spans 7200 km2. Its population is estimated at 112,000 inhabitants. intensively exploited supply region its capital, city (35,000 inhabitants). objective this work assess current resources using numerical modeling capacity future demands under impact climate change. RCP 2.6 (Representative Concentration Pathway) was used simulate scenario up 2100. Superficial recharge 3.86 × 106 m3/year. wellfield abstraction amounts 2.34 m3/year, accounting for 60% aquifer’s recharge. simulation indicates a declining trend table. These findings highlight fragile state aquifer, which critical socioeconomic stability Given vulnerability, any increase unsustainable, despite growing demand To tackle challenge, we recommend conducting further studies deepen understanding system implementing real-time monitoring network track changes.
