Applying pruning residues in the lanes of olive groves has become a popular practice because it is economical and accrues benefits for soil and water management. This study presents an analysis of the impact of different rates of pruning residue on soil properties, in particular related with soil quality. Over 4 annual campaigns, chopped pruning residues used as a mulch were analyzed in terms of composition, coverage and moisture content to evaluate their effects on the amount of soil organic carbon (−10 cm and −20 cm) and CO2 emissions, temperature and moisture. The experiment was carried out in a super-intensive olive orchard in Cordoba (SE, Spain) and used four amounts of fresh pruning residue: 7.5 t ha⁻1(T1), 15.0 t ha⁻1 (T2) and 30.0 t ha⁻1 (T3), with a control T0 = 0.0 t ha1. Mulch mean leaf fraction was 46.0 ± 17.5% (±SD) and initial water content, 24.8 ± 8.6%. The mulching benefits for soil moisture were observed in amounts of pruning residue >7.5 t ha⁻1, which are only produced in super-intensive olive groves or in orchards with high tree densities. The low impact of the treatments on soil moisture was explained by the dramatic annual variations in residue moisture contents, caused by the regimes of high temperatures and rainfall-evapotranspiration deficits inherent to the Mediterranean Basin climate. Thus, the mulching capacity only resulted efficient when the residues were still humid in spring. In addition, 15.0 t ha⁻1 of pruning residues was the threshold to provide significant increases in soil organic carbon at depths of 0–20 cm. Thus, accumulating pruning residue in lanes at rates of over 15 t ha⁻1 (T2 and T3) is more convenient than a uniform distribution with lower amounts, due to the low mineralization rates occurring during warm seasons and the larger inputs of OM increasing the annual balance of SOC.

En la Cordilleras Béticas litorales, estudios recientes indican un incremento de la erosividad de la precipitación. Así, es necesario avanzar en la estimación de la pérdida de suelo por erosión hídrica, principal agente geomorfológico en dicha zona. Este estudio aplica la ecuación RUSLE en dos cuencas de media montaña, con diferentes condiciones pluviométricas, durante el periodo 1997-2018; ambas cuencas presentan rasgos ecogeomorfológicos propios de la montaña mediterránea. En la aplicación, se han introducido cambios metodológicos en el cálculo de la estimación de pérdida de suelo y su validación: intensidad de lluvia diezminutal (I10), en vez de 30 minutos para el factor R; estimación de la cubierta vegetal para el factor C por medio del NDVI; y validación mediante inventario en campo de los componentes superficiales del suelo. Los resultados arrojan diferencias entre ambas cuencas dadas sus diferentes condiciones ecogeomorfológicas. La precisión dada por la I10 permite valorar mejor la estimación de pérdida de suelo y sus cambios espacio-temporales. La validación con componentes superficiales del suelo es mejor en la cuenca con condiciones ecogeomorfológicas más bióticas. Este trabajo tiene evidente utilidad para detección de zonas prioritarias ante la ejecución de políticas de reforestación y control de la erosión y generación de avenidas.

Concentrated flow erosion in Mediterranean cultivated areas is considered a major process of land degradation. Rills and ephemeral gullies in a 6.4 ha olive orchard catchment located in an intensive commercial farm which could represent a common degradation scenario in hilly areas, were measured and compared with the sediment loads at the outlet. 4 GPS survey campaigns were done between March‐2009 and March‐2014, for periods with cumulative precipitation ranging between 728 and 121 mm. Chopped pruning residues were kept on the lanes during campaigns 2‐4 whereas a grass cover crop was seeded in campaign 4. Rainfall, runoff and sediment loads were measured in a flume gauge station at the catchment outlet. The ratio of concentrated flow erosion to catchment sediment load varied between 1.0 and 35.0. Total concentrated flow erosion ranged between 25.0t•ha‐1 and 0.1t•ha‐1. Rill erosion was the dominant process on ephemeral gullies for three campaigns with a mean contribution to the total concentrated flow erosion of 55%. Rills clearly followed tractor tracks along the most parallel lanes to the maximum slope. Therefore, a change in traffic direction would be helpful to reduce the connectivity controlled by the spatial distribution of rows and lanes in the farm. Olive plantation distributions should prioritize hydrological criteria to adapt traffic patterns in olive farms as long as the tractor maneuverability and the risk of overturning are not adversely affected. Although the farmer only kept the cover crop for one campaign, it proved to be an efficient measure for interrupting rills along the lanes whereas pruning residues were effective for the control of interrill erosion. On‐site application of pruning residues reduced their handling and transport costs while increasing the soil fertility and soil cover. However, guidelines for the efficient application of pruning residues are still necessary in terms of residue rates and orientation.

Soil quality indexes (SQIs) are very useful in assessing the status and edaphic health of soils. This is particularly the case in the Mediterranean area, where successive torrential rainfall episodes give rise to erosion and soil degradation processes; these are being exacerbated by the current climate crisis. The objective of this study was to analyze the soil quality in two contrasting Mediterranean watersheds in the province of Malaga (Spain): the middle and upper watersheds of the Rio Grande (sub-humid conditions) and the Benamargosa River (semi-arid conditions). Field soil sampling was carried out at representative sites, and the soils were subsequently analyzed for various edaphic properties in the laboratory. From the resulting data, the mean values have been grouped and reclassified, and, based on a multicriteria evaluation, an SQI for the study region was generated. The results show that there are major differences between the two watersheds, with optimal soil quality values being found in the Rio Grande watershed (very high soil quality—34.26%), but more unfavorable values occurring throughout most of the Benamargosa River watershed (very low soil quality—63.33%). Thus, these results have been subjected to a validation process in the field.

Rainfall is the key factor to understand soil erosion processes, mechanisms, and rates. Most research was conducted to determine rainfall characteristics and their relationship with soil erosion (erosivity) but there is little information about how atmospheric patterns control soil losses, and this is important to enable sustainable environmental planning and risk prevention. We investigated the temporal and spatial variability of the relationships of rainfall, runoff, and sediment yield with atmospheric patterns (weather types, WTs) in the western Mediterranean basin. For this purpose, we analyzed a large database of rainfall events collected between 1985 and 2015 in 46 experimental plots and catchments with the aim to: (i) evaluate seasonal differences in the contribution of rainfall, runoff, and sediment yield produced by the WTs; and (ii) to analyze the seasonal efficiency of the different WTs (relation frequency and magnitude) related to rainfall, runoff, and sediment yield. The results indicate two different temporal patterns: the first weather type exhibits (during the cold period: autumn and winter) westerly flows that produce the highest rainfall, runoff, and sediment yield values throughout the territory; the second weather type exhibits easterly flows that predominate during the warm period (spring and summer) and it is located on the Mediterranean coast of the Iberian Peninsula. However, the cyclonic situations present high frequency throughout the whole year with a large influence extended around the western Mediterranean basin. Contrary, the anticyclonic situations, despite of its high frequency, do not contribute significantly to the total rainfall, runoff, and sediment (showing the lowest efficiency) because of atmospheric stability that currently characterize this atmospheric pattern. Our approach helps to better understand the relationship of WTs on the seasonal and spatial variability of rainfall, runoff and sediment yield with a regional scale based on the large dataset and number of soil erosion experimental stations.

We propose a graphical device—Three I’s of Anomalies (TIA) curves—that provides information on the incidence, intensity, and inequality (variability) of air temperature anomalies. We also propose a class of indices that help to compare different TIA curves when visual inspection alone is inconclusive. This class of indices identifies the 3 dimensions of anomalies and can be decomposed to evaluate air temperature anomalies according to different characteristics. Moreover, the results from this class of indices are consistent with the graphical device. We calculated TIA curves and a class of indices to analyze temperature anomalies in Málaga, Spain, from 2000 to 2017. Comparison of sequential 5-year periods indicated that maximum and minimum temperature anomalies have generally increased in frequency and intensity over time. The proposed index, which considers all dimensions, indicated that maximum and minimum temperature anomalies have increased. Analysis of different geographical areas indicated that inland areas had the greatest anomalies for minimum temperatures and mountainous areas had the greatest anomalies for maximum temperatures. Inland areas also had a stronger pattern of increasing anomalies. The coastline, especially in the western region, had weaker maximum and minimum temperature anomalies.

Southern Spain is characterized by a longitudinal pluviometric gradient over a distance of approximately 260 km, where the annual rainfall ranges from 1668 mm y−1 in the west (Sierra de Grazalema) to only 150 mm y−1 in the east (Cabo de Gata). Along this gradient during the last 70 years there have been trends of increasing rain in the west and increasing aridity in the east. The threshold annual rainfall level separating these regions is approximately 500 mm. For this study we selected two experimental basins having different geo-morphodynamic variables, each representing one side of this threshold. We used these basins for analysis of changes in land use and characterization of physiographic, soil cover, physical, chemical, and hydrological variables. We developed a database, applied statistical normalization, and then performed principal component analysis to identify the main geomorphological components explaining the variance. Our quantitative and cartographic results identified particular factors (vegetated areas, water resources, and soil degradation) that most control geomorphological processes, and explain the landscape dynamics in this region over recent decades.

Lighting bonfires in urban parks is a widespread practice. However, few studies have examined their impact on soil properties. The aim of this study was to analyze the impact of bonfires on the soil properties of an urban park in Vilnius, Lithuania. The properties studied were soil water repellency (SWR), aggregate stability (AS), soil organic matter (SOM) content, total nitrogen (TN), inorganic carbon (IC), pH, electrical conductivity (EC), extractable calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), aluminum (Al), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), boron (B), chromium (Cr), available phosphorus (P), silicon (Si) and sulfur (S). Soil ratios calculated were carbon/nitrogen ratio (C/N), Ca + Mg/(Na + K)1/2 (SPAR), Ca:Al and Ca:Mg. Three areas were studied: Site 1) Pinus sylvestris L. and Quercus robur L.; Site 2) Aesculus glabra Wild.; and Site 3) Pinus sylvestris L. and Acer plantanoides L. At each site, 20 samples were collected (10 within the bonfire area, 10 from a control area). The results showed significantly higher values of SOM, IC, pH, EC, Ca, Mg, Na, K, P, Al, Zn, Cu, Cr, S, C/N ratio, Ca:Al ratio and Ca:Mg ratio in bonfire soils than in control unburned soils. In bonfire soils, significantly lower values were recorded of SWR, AS, TN, SOM, Al, Mn, Fe, Cr, S and SPAR comparing to control soils. Most affected area by the bonfire was Site 1, which presented a marked increase in heavy metal content comparing to the control. The impact of soil heating was evident in AS, IC, pH, extractable Ca, Mg, Na, K, P, Al, Zn, Cu, Cr, S, and in its ratios. Protective measures are needed to limit bonfires and prohibit the burning of hazardous materials.

El incremento de la frecuencia de la torrencialidad en ámbitos mediterráneos es una cuestión preocupante y no solo desde el punto de vista hidrogeomorfológico, sino también desde el humano, socioeconómico e infraestructural. La definición del umbral de torrencialidad es clave para determinar la peligrosidad de un territorio determinado. En este estudio ajustamos diferentes clasificaciones de torrencialidad con los problemas e impactos identificados en dos áreas mediterráneas contrastadas de la provincia de Málaga, una de ellas caracterizada por un clima mediterráneo subhúmedo (Guadalhorce), y otra por un clima mediterráneo seco-semiárido (Axarquía). A partir del análisis de los datos pluviométricos de 18 observatorios (Red SAIH), los resultados determinan una escasa recurrencia de los eventos torrenciales predefinidos (>100 mm 24 h-1; >60 mm h-1), razón por la que proponemos el uso de un nuevo umbral de torrencialidad de menor duración, pero mucha más elevada intensidad (>10 mm 10 min-1), debido a que son muchos los episodios producidos por debajo de los umbrales anteriores, pero con consecuencias territoriales, como hemos constatado en el análisis mediático. La precipitación que se ajusta a este criterio ha sido definida como “precipitación geomorfológica” por su elevada capacidad de generar alteraciones en los componentes superficiales del territorio. Este tipo de precipitación presenta en ambos ambientes una alta recurrencia, un periodo de retorno prácticamente anual y una elevada erosividad.

Urbanization can increase sheet, rill, gully, and channel erosion. We quantified the sediment budget of the Los Laureles Canyon watershed (LLCW), which is a mixed rural-urbanizing catchment in Northwestern Mexico, using the AnnAGNPS model and field measurements of channel geometry. The model was calibrated with five years of observed runoff and sediment loads and used to evaluate sediment reduction under a mitigation scenario involving paving roads in hotspots of erosion. Calibrated runoff and sediment load had a mean-percent-bias of 28.4 and − 8.1, and root-mean-square errors of 85% and 41% of the mean, respectively. Suspended sediment concentration (SSC) collected at different locations during one storm-event correlated with modeled SSC at those locations, which suggests that the model represented spatial variation in sediment production. Simulated gully erosion represents 16%–37% of hillslope sediment production, and 50% of the hillslope sediment load is produced by only 23% of the watershed area. The model identifies priority locations for sediment control measures, and can be used to identify tradeoffs between sediment control and runoff production. Paving roads in priority areas would reduce total sediment yield by 30%, but may increase peak discharge moderately (1.6%–21%) at the outlet.

This presentation aims to quantify water and soil losses due to rainfall and specific soil management practices in combination with an analysis of which kind of weather type and rainfall event is able to cause specific surface flows and soil loss rates. As study area, we used the specific case of the sloping vineyards of the Montes de Málaga (South Spain). Two different plots were used: one cultivated area and poorly managed abandoned one. The in situ measures were conducted using sediment collectors to estimate sediment yield (g m−1) and surface runoff (L m−1) and an analysis of the weather conditions during each rainfall event using different meteorological sources. The weather types that generated the highest amount of rainfall on the studied area came from the western (32.6%) and southeast (28.2%) types. The less rainy weather type came from the south type (5.9%) and at the 500 hPa level. On the other hand, the heaviest rains came from the southwest (47.7%) and south (34.1%). As a first approach, it is confirmed that there is a bimodality in rainfall patterns. The results of soil erosion showed that there is a mixed mechanism depending on the state of the soil (vegetation cover, compaction, initial soil moisture), soil management (tillage, trampling effect and the use of herbicides) and the intensity of the surface flow, which is highly correlated to the total rainfall amount and intensity. In the poorly managed abandoned vineyard, the impact of the tillage in the past, the elimination of the vegetation cover to conserve the bare soil and its use as a grazing territory by cultivating barley, highly impacts on the generation of the highest erosive events.

Studies of post-fire soil status in Mediterranean ecosystems are common; however, few have examined the effects of long-term forest management after a wildfire on physicochemical soil properties. Here, we analyzed differences in soil properties attributable to long-term post-fire management and assessed the sustainability of these management practices in relation to the soil properties. The study area is located in Ódena in the northeast region of the Iberian Peninsula consisted of the control forest (burned more than 30 years ago), low density forest (LD; burned in a wildfire in 1986 and managed in 2005) and high density forest (HD; burned in a wildfire in 1986 and no managed). For soils from each plot, we measured soil water repellency, aggregate stability, total nitrogen (TN), soil organic matter (SOM), inorganic carbon (IC), pH, electrical conductivity, extractable calcium, magnesium, sodium, potassium (K), phosphorus, aluminum (Al), manganese (Mn), iron (Fe), zinc, copper, boron, chrome, silicon and sulfur and calculated the ratios of C/N, Ca + Mg/(Na + K)1/2, Ca/Al and Ca/Mg. Significant differences were found in TN, IC, SOM, pH, K, Al, Mn, Fe and C/N ratio (p < 0.05). All soil properties were found to have largely recovered their pre-fire values. Soils were affected by the post-fire management practices implemented 20 years after the fire, as reflected in their respective physicochemical properties, so that soil properties at the control and LD sites are more similar today than those at the control and HD sites. Thus, sustainable forest management can overcome soil degradation in areas affected by wildfire in the medium- and long-term by improving soil properties.

Prescribed fire is a common management practice in Mediterranean region to reduce the amount of fuel and to decrease the wildfire risk. The objective of this study is to assess the effect of a prescribed fire on some soil properties, hydrological response and vegetation recovery in experimental plots 5 years after. The results showed that: i) with the exception of electrical conductivity, the prescribed fire did not affect the analyzed soil properties, and ii) overland flow and sediment transport were increased during the first two years, returning to levels pre-fire, 5 years post-fire. The rainfall threshold for overland flow generation was lower during the following months after the prescribed fire owing to the depletion of the vegetation cover. Immediately after the fire, the vegetation cover was of 1.9%, being the three main soil surface components that dominated the hydrological response: charcoal and decayed wood; blackish and greyish ash, and bare soil. However, these areas decreased very rapidly during the second year following the fire, principally, owing to the regrowth of herbaceous plants and shrubs. In addition, the vegetation cover in burned plots was 16.1% higher than that measured in the unburned ones. Overall, the prescribed fire only had an impact on runoff and sediment transport in the two years post-fire, as consequence of vegetation removal.

We evaluated three definitions of heat wave (HW) and demonstrate that selection of the reference period and air temperature threshold used in the definition can affect the reported frequency of HWs. First, we propose an alternative definition of HW that is based on a moving reference period and specific air temperatures threshold for each calendar date. Then, we present a case study using data from five observatories in Malaga Province (Spain) from 1971 to 2016. We assessed the effect of a moving reference period (rather than a fixed reference period) and the definition of daily air temperatures threshold on the identification of anomalies in the definition of a HW. The results indicate that HWs can occur throughout the year. Finally, we propose incorporation of minimum daily air temperatures in two alternative definitions of HW. Our results indicate a high frequency of HWs in the summer months, in which HWs are mainly due to anomalous high Tmin and more frequent HWs in which maximum and minimum daily air temperature are exceeded from 2014 onwards. These new methods of defining a HW provide more accurate assessments of thermal discomfort.

La transición hacia una economía circular, en la que los recursos se conserven y se reduzca la generación de residuos, es una necesidad real para lograr una economía sostenible. Dentro de ella, cobra particular importancia la gestión de los residuos orgánicos o bioresiduos, tanto por la cantidad que suponen como por las implicaciones ambientales de su mala gestión. El objetivo de este estudio es evaluar los efectos de los bioresiduos como técnicas de restauración en paisajes forestales mediterráneos degradados. Para el mismo, se utilizan dos tipos de acolchados orgánicos generados como subproductos de actividades silvícolas y agrícolas en el entorno más inmediato al área de estudio: (i) bioresiduo tipo acolchado de restos de paja y; (ii) bioresiduo tipo acolchados de astillas de pino carrasco (Pinus halepensis Mill.). Nuestros resultados describen un aumento de la macro-agregación y las tasas de infiltración del suelo, en los primeros en los 24 primero meses, tras la adición de los dos tipos de bioresiduos. Ello ha permitido un mejor aprovechamiento del agua disponible en el perfil del suelo, generando aumento en las tasas de supervivencia. Desde un punto de vista de gestión forestal, tras este estudio, se puede sugerir el uso de bioresiduos en los procesos de restauración de cubierta en áreas forestales mediterráneas. Nowadays, the transition to a Circular Economy, in which wastes can be reduced, responds to a real and tangible need. Base on this, the management of organic residues acquires special prominence. This is because of the huge amount of wastes pr oduced and the environmental implications of their mismanagement. Based on this premise, the objective of this study is to evaluate the effects of certain types of organic residues as restoration techniques in a degraded Mediterranean area. Two types of or ganic wastes are selected: (i) straw mulch; and (ii) mulch with chipped branch of Pinushalepensis Mill . The wastes have been generated as secondary products during forestry and agricultural activities in the surrounding area. Independently of the treatment applied, our results show an increase in macro - aggregate stability and in the infiltration rates. This implies more available water for plants and, thus, the increment in the rates of survival plants. Consequently, the use of bio - wastes can be an effectiv e management technique to restore Mediterranean degraded areas.

El ratio LE (logarítmico exponencial) es una herramienta geomorfológica para ajustar perfiles longitudinales fluviales aplicando una ecuación. Los resultados permiten evaluar y cuantificar anomalías o rupturas (knickpoints) con diferentes orígenes. Para este caso, se analizaron 33 pequeñas cuencas de un sector de la costa septentrional del Mar de Alborán (Málaga-Granada, España), que se compararon entre sí utilizando ratio LE y otros modelos (Hack, Shulits y Green). En todos los casos se obtuvo mediante ratio LE una correlación lineal de R2≥0,95 (p

Modelling gully erosion in urban areas is challenging due to difficulties with equifinality and parameter identification, which complicates quantification 0of management impacts on runoff and sediment production. We calibrated a model (AnnAGNPS) of an ephemeral gully network that formed on unpaved roads following a storm event in an urban watershed (0.2 km2) in Tijuana, Mexico. Latin hypercube sampling was used to create 500 parameter ensembles. Modelled sediment load was most sensitive to the Soil Conservation Service (SCS) curve number, tillage depth (TD), and critical shear stress (τc). Twenty-one parameter ensembles gave acceptable error (behavioural models), though changes in parameters governing runoff generation (SCS curve number, Manning’s n) were compensated by changes in parameters describing soil properties (TD, τc), resulting in uncertainty in the optimal parameter values. The most suitable parameter combinations or “behavioural models” were used to evaluate uncertainty under management scenarios. Paving the roads increased runoff by 146–227%, increased peak discharge by 178–575%, and decreased sediment load by 90–94% depending on the ensemble. The method can be used in other watersheds to simulate runoff and gully erosion, to quantify the uncertainty of model-estimated impacts of management activities on runoff and erosion, and to suggest critical field measurements to reduce uncertainties in complex urban environments.
