Citrus is one of the most valuable crops in Syria, with largest production areas being coastal provinces Tartus and Latakia, where this study was performed. A companion paper reported on basal crop coefficients derived from field water balance performance assessment various irrigation methods used a citrus orchard located same region. That evidenced need for improved management water, mainly reducing applications increasing productivity, thus leading to current research. The main objectives consisted (i) providing set reliable (Kcb) average (Kc) be practice orchards Syrian area, while accounting diversity characteristics observed; (ii) estimate seasonal consumptive use typical under different climate-demand deficit-irrigation scenarios; (iii) assess possible savings related yield reductions. previously calibrated model SIMDualKc these purposes. computed Kcb values mid-season demand ranged 0.52, when plant density low, 0.84, very high. corresponding Kc values, which further reflected impact drip controlling soil evaporation, were 0.72 0.97, respectively.

Abstract Mulching is a widely adopted agronomic practice, often used as water-saving strategy due to its effectiveness in reducing soil evaporation. However, effects vary depending on the materials and extent of mulch coverage. Consequently, impacts mulching may differ considerably across production systems, preventing establishment reliable guidelines for irrigation water management. The objective this study comprehensively review existing literature that compares versus no-mulching management, aiming gain deeper understanding evaporation (E s ), crop coefficients (K c actual evapotranspiration (ET act ). 58 studies were selected. impact was particularly notable early stages, when not fully covered. Data shows plastic films more effective K than organic materials. effect, while evident during diminished throughout rest season. Black stages compared other colored plastics, relative decrease , but effect also diminishes Building upon these findings, provides expected reductions values based type crop, stage, material most each cropping system.

Understanding microclimate spatial variability is crucial for sustainable and optimised grape production within vineyard plots. By employing a combination of model (NicheMapR) multiple climate data sources, this study aimed to achieve microclimatic analysis in two plots, Quinta do Bomfim (northern Portugal) Herdade Esporão (southern Portugal). This approach provides an innovative 10 m resolution variables. incorporated local station hourly with quantile mapping bias correction on the ERA5-land data. The output was employed perform EURO-CORDEX ensemble. Climate extreme bioclimatic indices specifically targeted viticulture were calculated each plot. scale analysed identify potential shifts temperature extremes, precipitation patterns, other climatic variables cultivation specific significance analyses higher areas intricate topography, while smooth slopes, variation determined be negligible.

Abstract Wetlands, namely the riparian ones, play a major role in landscape and water resources functionalities provide enormous opportunities for ecosystems services. However, their area at globe scale is continuously decreasing due to appropriation by riverain communities or allocation of other uses, irrigation, prejudice natural wetlands. Due high competition water, agricultural calculation vegetation evapotranspiration (ET c ), i.e. consumptive use wetland ecosystems, mandatory determining supply–demand balance various scales.

Abstract Portugal, a leading olive oil producer, boasts six Protected Denomination of Origin (PDO) regions, with distinct orchard (OR) densities (traditional rainfed to super-intensive irrigated). This study aimed assess future drought and aridity conditions the impacts on ORs located in PDOs. Therefore, indicators were considered for historical (ERA5: 1981–2000) periods (2041–2060; 2081–2100), anthropogenic forcing scenarios (RCP4.5 RCP8.5), using 7-member ensemble global climate models. From Spearman’s correlation analysis, Annual Mean Aridity (AIA) was selected as most representative indicator conditions, which exposed. Readily Available Soil Water (RAW; mm) represent available soil water reservoir trees. Moreover, Olive Drought Risk Index (ODAR) developed determine each OR's risks. index that AIA RAW weighted by OR density fractions. In future, southern Portugal will be more arid (0.69) than northern central (0.60). shows lower PDOs (< 60 regions (> 90 mm). These results suggest south exposed stress regions. According ODAR, low high risk mainly parts ORs, moderate predominate. south, however, very high, means tree growth, fruit development, quality could negatively affected.
