This paper examines the differences in agricultural water application per crop ton output in semi-arid jurisdictions in the Jordan Basin, focusing on Israel and Jordan, with some analysis relevant to Palestine. In order to understand differences in water application, it delivers a nationally averaged assessment of applied water application for 14 key regional crops, with most cases suggesting Israeli best practice in water application per unit crop. The paper draws on a secondary assessment of agricultural water intensity and primary data from farmer interviews to demonstrate differences in applied water productivity and agricultural context. The analysis suggests a conservative estimate that a difference of 168 Million Cubic Meters (MCM)/yr (33% of agriculture and 18% of national total) exists in terms of water application for a given crop production in Jordan when compared with Israel. The paper then proposes further work required to establish how differences in water application might translate into differences in agricultural water productivity, and thereby potential water savings that might enable growth of production within current agricultural allocations, allowing new future resources to be allocated to other economic and social needs. The paper also delivers a preliminary analysis of the political and institutional landscape for implementation, assessing the challenges of institutional silos and overlap that some policy stakeholders see as hindering cross-sectoral progress. The paper concludes by examining the limitations of the analysis, and it proposes future work to deepen the robustness of results and examines some of the challenges facing improved agricultural water productivity and changing farm behaviour in the region.
This chapter examines trends in water resources used in Jordan and Israel. Specifically it illustrates how these two economies have circumvented significant limits in their natural freshwater resource endowment to enable continued economic and population growth despite static or declining water availability. Using the concept of resource decoupling, it identifies four specific mechanisms by which economies can decouple their water needs from water availability, including economic diversification, food imports, agricultural water productivity, and nonconventional water resource development. Each of these mechanisms are illustrated for the two countries, including technical and political processes shaping their adoption. The chapter also critiques existing conceptualizations of decoupling relative to the water-specific model, highlighting the importance of understanding the unique characteristics of scarcity, flows, and substitutability of water at a global scale. Finally the chapter nests decoupling within the market modes framing this volume, before evaluating the risks and trade-offs inherent in decoupling strategies.
