In my thesis essay I have researched the impact of water management on the outcome of peace negotiation and treaty in the case of Israel and Syria. My research question was “How should the water resources of the Golan Heights be addressed in a coming peace treaty between Israel and Syria for this treaty to be sustainable?”. I emanated from the theory advocated by researchers Ohlsson, Homer-Dixon and Gleick, arguing that the detailed incorporation of water management in negotiations as well as in a final peace treaty between countries is crucial for these to be sustainable. I used this theory in analysing the extended data related to the two countries’ water resources and water policies, as well as two previous rounds of negotiation. I came to the conclusion that for any future negotiation to lead to a sustainable peace agreement between the two countries, it is crucial for them to establish very detailed stipulations on the shared water resources. Both Israel and Syria are in great need of accessing and controlling water resources, however Israel is much more dependent than Syria on the waters of the Golan Heights. When an internationally recognized borderline between the countries in the future will be established, it will by default be situated on or closely connected to vital water resources. Therefore the water management, including use of and withdrawal from these resources needs to be clearly regulated, otherwise conflict might rise again between the two countries. If water management would be included in the peace treaty in as thoroughly manner as the theorists suggests, this would enable the treaty to become sustainable, as well as make feasible the resolution of related conflicting matters.
