“…However, there is limited information about surface runoff, and soil erosion under varying soil management in such orchards. In addition, there have been several studies based on effects of soil conservation managements on soil and water loss in orange, citrus, apricot and olive orchards (Abrisqueta et al, 2007;Cerdà et al, 2009a, b). However, it is still unknown if these management techniques also would be beneficial in rainfed jujube orchard for long-term production in Chinese Loess Plateau.…”

“…Almond (Faulkner, 1995), persimmon , and apricot (Abrisqueta et al, 2007) orchards have also shown high erosion rates, but little research has been carried out comparing agriculture land management in fruit orchards. Also no research has been reported in other orchards such as apples, cherries or pears even though the worldwide land area devoted to fruit production is growing due to demand for fresh fruits and juices (Jackson et al, 2011).…”

Soil erosion is extreme in Mediterranean orchards due to management impact, high rainfall intensities, steep slopes and erodible parent material. Vall d'Albaida is a traditional fruit production area which, due to the Mediterranean climate and marly soils, produces sweet fruits. However, these highly productive soils are left bare under the prevailing land management and marly soils are vulnerable to soil water erosion when left bare. In this paper we study the impact of different agricultural land management strategies on soil properties (bulk density, soil organic matter, soil moisture), soil water erosion and runoff, by means of simulated rainfall experiments and soil analyses. Three representative land managements (tillage/herbicide/covered with vegetation) were selected, where 20 paired plots (60 plots) were established to determine soil losses and runoff. The simulated rainfall was carried out at 55 mm h-1 in the summer of 2013 (<8% soil moisture) for one hour on 0.25 m2 circular plots. The results showed that vegetation cover, soil moisture and organic matter were significantly higher in covered plots than in tilled and herbicide treated plots. However, runoff coefficient, total runoff, sediment yield and soil erosion were significantly higher in herbicide treated plots compared to the others. Runoff sediment concentration was significantly higher in tilled plots. The lowest values were identified in covered plots. Overall, tillage, but especially herbicide treatment, decreased vegetation cover, soil moisture, soil organic matter, and increased bulk density, runoff coefficient, total runoff, sediment yield and soil erosion. Soil erosion was extremely high in herbicide plots with 0.91 Mg ha-1 h-1 of soil lost; in the tilled fields erosion rates were lower with 0.51 Mg ha-1 h-1. Covered soil showed an erosion rate of 0.02 Mg ha-1 h-1. These results showed that agricultural management influenced water and sediment dynamics and that tillage and herbicide treatment should be avoided

“…Themes that emerge from the limited research on hydrological processes in the world's drylands highlight the significant role of processes related to water connectivity, including the lateral and longitudinal hydrological redistribution of surface water and surface-groundwater interactions, including in work from northeastern Brazil (Costa et al, 2012), Africa (Bonell and Williams, 2009;Bauer et al, 2006) and Spain (Abrisqueta et al, 2007;Ceballos and Schnabel, 1998;Nicolau et al, 1996). Ecohydrology and the interaction of vegetation with rainfall, topography, aquifers and runoff is also highlighted as significant (Ludwig and Tongway, 2000;Ludwig et al, 1997Ludwig et al, , 2005Wilcox and Newman, 2005;Gifford, 1978;Callow, 2011;Eamus et al, 2006;Turnbull et al, 2012;Wang et al, 2012).…”

“…The constructed waterway intervention is very different to the deep-drainage approach used to combat rising groundwater salinity in valley floor locations in the Wheatbelt region of Western Australia (Ali et al, 2004;Barrett-Lennard et al, 2005;Pannell, 2001;Pannell and Ewing, 2004;Coles et al, 1999). These are based on digging a ditch or drain to a depth of around 2m to intercept groundwater and dispose of the saline groundwater effluent downstream (Ali et al, 2004). Deep drainage offers limited or no economic return on investment for broadacre farming (Ali et al, 2004;Pannell, 2001;Pannell and Ewing, 2004) and has detrimental downstream environment impacts, with discharge often being acidic (pH 1.9-3.8) and high in salinity (measured as up to 147 000 mg L −1 or 4.5 times seawater salinity) (Stewart et al, 2009).…”

Abstract. Secondary dryland salinity is a global land degradation issue. Drylands are often less developed, less well instrumented and less well understood, requiring us to adapt and impose understanding from different hydro-geomorphological settings that are better instrumented and understood. Conceptual models of secondary dryland salinity, from wet and more hydrologically connected landscapes imposed with adjustments for rainfall and streamflow, have led to the pervasive understanding that land clearing alters water balance in favour of increased infiltration and rising groundwater that bring salts to the surface. This paper presents data from an intra-catchment surface flow gauging network run for 6 years and a surface-water–groundwater (SW–GW) interaction site to assess the adequacy of our conceptual understanding of secondary dryland salinity in environments with low gradients and runoff yield. The aim is to (re-)conceptualise pathways of water and salt redistribution in dryland landscapes and to investigate the role that surface water flows and connectivity plays in land degradation from salinity in low-gradient drylands. Based on the long-term end-of-catchment gauge, average annual runoff yield is only 0.14 % of rainfall. The internal gauging network that operated from 2007–2012 found pulses of internal water (also mobilising salt) in years when no flow was recorded at the catchment outlet. Data from a surface-water–groundwater interaction site show top-down recharge of surface water early in the water year that transitions to a bottom-up system of discharge later in the water year. This connection provides a mechanism for the vertical diffusion of salts to the surface waters, followed by evapo-concentration and downstream export when depression storage thresholds are exceeded. Intervention in this landscape by constructing a broad-based channel to address these processes resulted in a 25 % increase in flow volume and a 20 % reduction in salinity by allowing the lower catchment to more effectively support bypassing of the storages in the lower landscape that would otherwise retain water and allow salt to accumulate. Results from this study suggest catchment internal redistribution of relatively fresh runoff onto the valley floor is a major contributor to the development of secondary dryland salinity. Seasonally inundated areas are subject to significant transmission losses and drive processes of vertical salt mobility. These surface flow and connectivity processes are not only acting in isolation to cause secondary salinity but are also interacting with groundwater systems responding to land clearing and processes recognised in the more conventional understanding of hillslope recharge and groundwater discharge. The study landscape appears to have three functional hydrological components: upland, hillslope “flow” landscapes that generate fresh runoff; valley floor “fill” landscapes with high transmission losses and poor flow connectivity controlled by the micro-topography that promotes a surface–groundwater connection and salt movement; and the downstream “flood” landscapes, where flows are recorded only when internal storages (fill landscapes) are exceeded. This work highlights the role of surface water processes as a contributor to land degradation by dryland salinity in low-gradient landscapes.
