The present study was conducted at Matrouh Governorate, where the area exlends along the coastal plain southward depth 2.5 km (at El Alamien) and disappears in other places, i.e. Fuka and Ras El-Hekma. Due south the coastel phin the plateau rises gradually until Siwa Oasis, where the altitude falls down to around 27 m below sea level. The study aims at evaluating the agricultural resources availability of irrigation water resoures, arable land, the current status of the rainfed agricultural system adopted, in addition to productive and economic efficiency assessment. The study indicited that the net yield of irrigated wheat crops was 2210 pounds/acre, while the net return of the opportunity cost of about 492.8 pounds/acre, while showing that the opportunity cost of agriculture represents the best investment opportunity rain-fed wheat crop cultivated rainy system, where there has been a return of about 151.9 pounds/acre, while they cause the loss of about 460 pounds/acre. Also, data showed that the net yield of the irrigated olive crops was about 6450 pounds/acre, while the net return of the opportunity costs of about 1636.9 pounds/acre, which means productive activity preference for the cultivation of the crop olive about the opportunity cost of this activity represents a better investment opportunity. This study has led to some recommendations, including the need to develop a specific time-plan for the establishment of infrastructures helping in rain water harvesting and provisim. Altmioalah sources needed to identify dams and reservoirs needed for the absorption and maintenance and rainwater.
