Development in the third world is greatly dependant on assistance and cooperation with developed counties. Agricultural engineering can play an important role in the educational, economical and social development of under developed countries in the world due to the nature of work that requires interaction with local people. In this paper, background information is presented about Palestine and Southern West Bank. In addition, many on-going long-term development projects in Southern West Bank are presented as examples of cooperation. Regional and international cooperation in the field of agricultural engineering are shown to be important tools that would lead to the training of Palestinians and to the transferring of knowledge and technology. It is suggested here that this cooperation would lead to interaction and building of tolerance between nations that in turn would be one of the factors that would lead to sustainable just peace in the Middle East.
