“…Also, the mean soil EC was significantly higher under DI 50 treatment than DI 75. These results agree with the findings of Díaz et al (2013) and Aragüés et al (2014a), who reported that soil salinity and sodicity were generally higher for deficit irrigation than for full irrigation treatments.…”

“…Moreover, DI raised the soil SAR when compared with full irrigation with FW. This is similar to the findings of Díaz et al (2013) and Aragüés et al (2014a). In contrast, DI irrigation with RW and BW treatments led to lower soil SARs than FI.…”

“…Similar views have been expressed by many investigators who found increases in soil salinity and sodicity in the top soil layer when irrigating with RW (Hassanli et al, 2008;Amiri et al, 2008;Laurenson et al, 2012). Also, other studies involving irrigation with desalinated seawater and RW reported increased soil salinity and sodicity, which were found to be generally higher in DI than in FI treatments (Díaz et al, 2013;Aragüés et al, 2014a). As mentioned earlier, the high sodium content in RW influenced the SAR, which could lead to reductions in soil permeability and subsequent restrictions of water flow within the soil profile (Hassanli et al, 2008).…”

“…Significant Bs increases in soil as a result of irrigation with RWW and DBW have been reported by other authors [32,33]. The high B content in the RWW and DBW in the present study, above the recommended limit for irrigation water (~0.75 mg·L ) respectively, which is not effectively reduced by reverse osmosis during desalination.…”

Abstract:In a global context in which obtaining new energy sources is of paramount importance, the production of biodiesel from plant crops is a potentially viable alternative to the use of fossil fuels. Among the species used to produce the raw material for biodiesel, Jatropha curcas L. (JCL) has enjoyed increased popularity in recent years, due partly to its ability to grow in degraded zones and under arid and semi-arid conditions. The present study evaluates the potential for JCL production under irrigation with non-conventional water resources in abandoned agricultural soils of the island of Fuerteventura (Canary Islands, Spain), which is one of the most arid parts of the European Union. JCL growth and productivity are compared during the first 39 months of cultivation in two soil types (clay-loam and sandy-loam) and with two irrigation water qualities: recycled urban wastewater (RWW) and desalinated brackish water (DBW). The results indicate that JCL growth (in terms of plant height and stem diameter) was significantly influenced both by soil type and water quality, with better development observed in the sandy-loam soil under RWW irrigation. Productivity, measured as cumulative seed production, was not affected by soil type but was affected by water quality. Production under RWW irrigation was approximately seven times greater than with DBW (mean ~2142 vs. 322 kg·ha 6903 were found to be key factors in the greater productivity observed under irrigation with this type of water.

“…Particularly, in extremely arid areas, such as the SE of Gran Canaria, with a high evaporative demand (ETPo~1786 mm year −1 ; period 2001-2018) and very low precipitation (~94 mm year −1 ; period 2008-2017), the accumulation of soluble salts in the upper zone of the profiles might be a limiting factor (i.e., osmotic effects) for production in sensitive and moderately sensitive crops if no adequate leaching fractions are applied. Therefore, Diaz, et al (2013) [31] reported, also in a very arid insular environment, a significant increase in soil salinity, when compared to rainfall soils, after 20 years of irrigation with DSW (average EC~580 µS cm −1 ).…”

The growing need for alternative water resources for irrigation has led to advanced technological developments, which are addressing some of the challenges that our planet is facing regarding the water supply. The Canary Islands Archipelago (Spain) is a singular territory with several years of desalination experience while using desalinated seawater (DSW) for agricultural purposes. The current paper will address the conducted research of one of the case studies done into the Horizon 2020 project MAGIC, with the aim of analyzing the use of DSW for crop production in the Southeast of Gran Canaria Island. A methodology of surveying farmers in the area has been put in practice, as well as an assessment of potential soil degradation risks that are related to DSW irrigation (with fifteen years of DSW data). Additionally, local good practices to improve the DSW quality for irrigation are discussed. This study demonstrates an excellent endorsement of the surveyed farmers in the studied area regarding the use of DSW for irrigation: the strategy of combining this type of water with other water resources, such as groundwater and/or reclaimed water is very frequent and it can guarantee water and food security in the island’s territory.
