CLIMATE–TECHNOLOGY INTERACTIONS AND THEIR IMPACT ON AGRICULTURAL PRODUCTION IN ALGERIA

Abstract


This study examines the impact of climatic and technological changes on agricultural productivity in Algeria during the period 1999–2023 using the ARDL model. The results confirm the existence of a long-run equilibrium relationship between agricultural value added and its climatic, technological, and structural determinants. Productive inputs, particularly fertilizers and water resources, positively affect agricultural performance, whereas rising temperatures and inefficient irrigation management exert negative effects. The findings also show that technological development contributes to strengthening the sector’s capacity to cope with climate-related challenges. In addition, persistent structural constraints, including low labor productivity and the prevalence of traditional production practices, continue to limit productive efficiency. The error correction mechanism confirms the sector’s ability to adjust toward long-run equilibrium following short-term shocks. Overall, the results highlight the importance of improving resource-use efficiency, promoting technological modernization, and strengthening climate adaptation policies to support sustainable agricultural development in Algeria.
