The purpose of this article is to investigate the agricultural potential for a selected area in the northeast of Libya. The area is Wadi Derna which lies in the eastern slope of Jabel El Akhdar. The agricultural project is a multi-purpose scheme involving several inter-linked aims. The main ambition is to increase the total percentage of land under crops and to do this by replacing shifting cultivation by settled farming under irrigation.
A modified Penman formula was used to calculate the potential evaporation and the deficit of water in the area and to suggest the need for supplementary irrigation.
