Ezzeddine B. Mosbah is an agricultural and rural-development economist whose academic formation includes a Ph.D. in Agricultural Economics and Rural Development from the National Agricultural Institute of Tunis (INAT, 2007), preceded by a specialized engineering degree in Economy and Rural Development (1996) and an agro-economist engineering degree (1993) from the same institute. With more than two decades of professional experience across ministries of Agriculture, Education, and Employment & Vocational Training in Tunisia and, since 2017, as Assistant Professor at King Faisal University (KSA), and previously at institutions in Tunisia, he has taught courses ranging from Agricultural Economics and Water Economics to Development Economics, Statistics, Operations Research, and Project Feasibility Studies. His research interests revolve around agricultural economics, rural development, labor and employment markets, efficiency and impact evaluation, environmental economics and waste management, food marketing (notably date-palm economics), water desalination, and econometric/operations-research methods. According to publicly available citation data, his h-index is 3 with 33 citations and 6 documented publications — a baseline that signals a career still consolidating its scholarly impact. Among his work is the monograph Rationaliser le Comportement Public: la Formation un Exemple (2015). Through empirical analyses of water-use efficiency, agricultural investment incentives, municipal waste impacts, technical efficiency of farms, and environmental sustainability, Mosbah contributes to policy-relevant knowledge in both MENA and Gulf contexts. His ongoing focus remains on efficiency measurement, sustainable rural development, and socio-economic evaluation of agricultural and environmental systems.
