It belonged to a peaceful and quiet village where old farmers seemed to have all the time to Chapter 1 wait for their irrigation turn. While we walked through the irrigation system we saw remnants of the Moorish past: the acequia irrigation infrastructure, aqueducts, water mills and a tower – the shadow of which used to indicate when a ‘water turn’ was finished. While admiring the traditional irrigation system, I heard farmers talk about the modernization of Yunquera: they were planning to install drip irrigation. These plans of the Yunquera water users confused me as the combination of modern drip irrigation with a traditional farmer managed irrigation system seemed a contradiction. In conventional irrigation thinking, drip irrigation - and in particular its capacity to apply precise amounts of water to plants, accurately matching water deliveries to crop water requirements and thereby increasing water use efficiencies - is associated with progress and modernity. Converting a traditional farmer managed irrigation system to drip irrigation would therefore imply an irreversible modification of age-old water infrastructures and management systems in favour of supposedly more rational and efficient methods and technologies. It would, in other words, imply the destruction of a beautiful cultural heritage inscribed in landscapes and people. It was because I cherished this cultural heritage that my impulse was to reject the idea of drip irrigation in Yunquera. I returned to Yunquera in 2008 (for my MSc thesis research) to understand why drip irrigation would be installed in Yunquera. I did not only aim to understand the reasons for installing drip irrigation because of my own discomfort with modernizing this traditional irrigation system but also because the most logical reason for installing drip irrigation – increasing irrigation efficiency - was absent. As no-one had complained about the availability of water, there seemed little justification for installing efficient drip irrigation here. In retrospect, I had a romanticized view of farmer managed irrigation systems (FMIS) and an engineering biased view of drip irrigation. Approaching FMIS as markers of tradition and drip irrigation as an icon of efficiency and modernity indeed implied that the two would never be able to ‘marry’, as it places them in different worlds. These categories that I used to make sense of drip irrigation and of FMIS mutually excluded each other: choosing one automatically meant rejecting the other. While I was afraid that drip irrigation would destroy a rural ideal, others (aligning with a modernization discourse) would instead see Yunquera’s traditionality as a hindrance to the efficient use of the country’s scarce 11 Chapter 1 water resources. While I felt attracted to the idyll of the past, many irrigation engineers would instead be attracted by the introduction of drip irrigation which would help bring about a modern, entrepreneurial future based on a more efficient use of water. 1.1.1 Modernization thinking in irrigation Conventional irrigation thinking favours a future in which water is used ever more rationally and efficiently (van Halsema, 2002; Bolding, 2004; Zwarteveen, 2006). Irrigation modernization thinking has “strong positivist beliefs in technology as a motor of progress” and “perceives development as an evolutionary, linear process of change which takes societies from their pre-modern, primitive, phase through a series of stages towards the final destination of modernity” (Zwarteveen, 2006, p.53). In this line of thinking, drip irrigation is favoured over supposedly more wasteful surface methods of irrigation. Its use will help achieving a desired future: “Use of drip irrigation methods in field crops is inevitable in the near future because of the problem caused by crop patterns and traditional irrigation methods.” (Topak et al., 2011 p.80). Indeed, in the epistemic communities of irrigation scholars, the term ‘modernization’ is used to refer to a conversion from supposedly backward and wasteful surface irrigation methods to supposedly more efficient and rational irrigation technologies and modes of management. The latter for instance include canal lining, automatically controlled water distribution methods, water pricing and drip irrigation. In irrigation thinking, modernization thus refers to the “upgrading” (Burt, 1999, p.15) of irrigation systems, aimed at attaining higher water use efficiencies and water productivities through the improved control of water (van Halsema, 2002). As drip irrigation enables full control over water and thus allows applying precisely the right amount of water to crops at the right moment it represents an icon of the engineering ideal to increase irrigation efficiencies.
