From its outset, the Zionist Movement's aspiration to turn the Holy Land (Palestine, under the Ottoman and the British Mandatory's rule) into the Jewish state relied upon the assumption that the area's ‘productive capacity’ was sufficient to sustain the millions of Jews who would immigrate to the land. This assumption was not obvious. Rather, it required empirical and political support. The primary challenge was to create a positive worldwide opinion of the Zionist vision. That is, to persuasively demonstrate that the difficulties engendered by the scarcity of water in the semi-arid climate of the land could be overcome. To this end, in the mid-1940s, the Zionist leaders commissioned the service of the best-known soil and water engineering experts of the time: Walter C. Lowdermilk and James B. Hays. The results of the water surveys conducted were made public in Lowdermilk’s, "Palestine, Land of Promise" (1944) and Hays’," T.V.A on the Jordan" (1948). The two publications built a narrative that asserted that proper water management would generate ample resources for the projected massive immigration to Palestine. However, during the first decade of its existence, the Israeli government reversed its original allegation of water. It was no longer an abundant resource, but instead one of profound scarcity. To reinforce this narrative, the government utilized effective propaganda, like the motto – “Save every drop”. Why? The proposed lecture will be based on visual art and a video clip. Its aim is to reveal an unknown aspect of the legal interests in the water availability conception during the early years of the Israeli Statism.
