[1] Quantification of global land evapotranspiration (ET) has long been associated with large uncertainties due to the lack reference observations. Several recently developed products now provide capacity estimate ET at scales. These products, partly based on observational data, include satellite-based surface model (LSM) simulations, atmospheric reanalysis output, estimates empirical upscaling eddy-covariance flux measurements, and water balance datasets. The LandFlux-EVAL project aims...
Soil water infiltration is an important process whose behavior depends on external factors and soil properties, which vary depending the type of soil. The present paper aims to establish parameters determine steady‐state rate six Orders, all formed volcanic materials—Andisols (nonallophanic, allophanic, vitric), Inceptisols (typic, andic, vertic), Alfisols, Vertisols, Aridisols, Entisols (psamments, fluvents), contribute differences between them. study was conducted at 108 sites island...
Children under 15 years of age living in the household a tuberculosis case constitute very vulnerable group to infection (TBI). The objective this study was determine prevalence TBI and risk factors associated with presenting group, considering sex, age, migratory status as axes inequality. A population-based, analytical, cross-sectional observational carried out city Barcelona period 2003–2022. population contacts index cases pulmonary TB reported Public Health Agency analyses were...
ABSTRACT: Soil erosion and infiltration are influenced by chemical, mineralogical, physical soil properties. Typically, increases with decreasing infiltration. Undisturbed Andisols considered to be highly stable resistant water erosion. A wide variety of can found on the island Tenerife (Canary Islands). The objective present paper was determine rate five assess influence deforestation a change in vegetation rate. Apparent hydraulic conductivity measured using double ring infiltrometer soils...
Abstract Depending on the severity of fire, forest fires may modify infiltration and soil erosion processes. Rainfall simulations were used to determine hydrological effects fire Andisols in a pine burned by wildfire 2007. Six zones with different severities compared unburned zones. Infiltration, runoff loss analysed slopes 10% 30%. Forest floor properties evaluated. Unburned exhibited relatively low (23 16 mm h −1 30% slope angles, respectively) high average runoff/rainfall ratios (43% 50%...
In a global context in which obtaining new energy sources is of paramount importance, the production biodiesel from plant crops potentially viable alternative to use fossil fuels. Among species used produce raw material for biodiesel, Jatropha curcas L. (JCL) has enjoyed increased popularity recent years, due partly its ability grow degraded zones and under arid semi-arid conditions. The present study evaluates potential JCL irrigation with non-conventional water resources abandoned...
Natural soil salinization and sodication processes that restrict or prevent crop growth are commonplace in arid regions. In saline‐sodic soils of parts the Canarian archipelago, where annual rainfall is <150 mm, a traditional agriculture system has been developed using basaltic tephra mulch. This enabled dry farming to take place even under most adverse natural conditions. The present work compares salinity‐sodicity cultivated layer were covered with 10 15 cm mulch as recently 20 yr ago...
Summary Soil temperature influences both soil formation processes and land use possibilities, is a classification criterion in some systems. Vegetation cover one of the factors that affects temperature. In this paper, we estimate classes regimes, using Taxonomy, for Andosols located parts island Tenerife, Canary Islands, Spain, which are influenced by trade winds. The study focuses on soils under three types natural vegetation – cloud forest, tree‐heath woodland pine forest adjacent plots...
We studied the soil temperature regimes of volcanic island Tenerife (Canary Islands, Spain), which is situated in Atlantic Ocean between 27 and 28° N. The 2034 km 2 size its highest point 3718 m above sea level. Direct measurements were taken during a 4‐yr period at 103 sites, depth 50 cm, altitudinal sequences from north south slopes island. In contrast to continental situations, all latitudes are found within small area Seven nine considered by Soil Taxonomy have been...
Large areas of the Canarian archipelago are catalogued as aridic according to U.S. soil taxonomy. A traditional system cultivation, based on application a mulch layer tephra, is widely practiced. The objective this work compare classification soils with and without using U. S. taxonomy, illustrate problems in estimating moisture regime basis meteorological data. In study natural an adjacent mulched 12‐cm basaltic tephra was characterized gravimetric measurements, taken over period >1 yr,...
Abstract Quantity‐intensity (Q/I) curves and derived parameters provide general information about soil K availability. This investigation was conducted to study the relationship between Q/I properties of 24 calcareous Inceptisols Vertisols southwestern Spain. Three were considered: activity ratio at equilibrium (AR o ), buffer power (BP in 20 × 10 −3 30 activity‐ratio range 20‐30 ). Close linear correlations found powers BP ) cation‐exchange capacity (CEC) ( r 2 = 0.949 0.888, respectively),...
