Abstract
The objective of this study was to quantify the effects of economic and population growth under climate variability on annual freshwater abstractions in Algeria over the 1990-2020 period. Utilizing the Autoregressive Distributed Lag (ARDL) modeling approach, the findings demonstrate statistically significant positive long-term impacts of temperature and demographic expansion. The empirical results indicate that annual freshwater withdrawals increase by 4.23 units per unit increase in temperature and by 3.97 units per unit increase in population growth. While economic growth shows a positive coefficient, it lacks statistical significance. Short-run dynamics reveal a positive association between temperature and annual freshwater withdrawals, with each unit increase in temperature corresponding to a 0.47-unit increase in water abstractions. These findings establish climate change as a principal determinant of escalating water stress, attributed to reduced precipitation and elevated temperatures, thus highlighting the critical necessity for sustainable interventions to ensure water security.
