Abstract Soil degradation phenomena, including water erosion and physical biological processes, have already been reported in rangelands of southwestern Spain. The increasing numbers livestock since 1986 highlighted as one the key causes. main goal this work is to analyse effects excessive number animals on soil quality pasture production privately owned farms dedicated extensive ranching. properties surface cover, production, rainfall land management variables such density were analysed...
Abstract An assessment of sensitivity to land degradation has been carried out in the Extremadura region, SW Spain, by means a modelling approach developed European Commission funded MEDALUS project (Mediterranean Desertification and Land Use) which identifies such areas on basis an index (Environmentally Sensitive Area index, ESA index) that incorporates data environmental quality (climate, vegetation, soil) as well anthropogenic factors (management). Two maps (ES) with different legend...
In light of growing interest in data-driven methods for oceanic, atmospheric, and climate sciences, this work focuses on the field data assimilation presents analog (AnDA). The proposed framework produces a reconstruction system dynamics fully manner where no explicit knowledge dynamical model is required. Instead, representative catalog trajectories assumed to be available. Based catalog, combines nonparametric sampling using forecasting with ensemble-based techniques. This study explores...
Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. total, 5023 curves were collected across all continents in SWIG These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its extensive geographical coverage, cover research...
Land abandonment is widespread in the Mediterranean mountains. The impact of agricultural results a shift ecosystem evolution due to changes soil erosion, but little known about long-term and water losses. This paper uses 11 years measurements two paired plots (abandoned vs control) with four subplots determine how losses evolved after within an parcel. For (2004–2005) both were under tillage, 2006 one plot was abandoned. monitored measured runoff sediment concentration each rainfall event....
Transdisciplinary approaches that provide holistic views are essential to properly understand soil processes and the importance of society will be crucial in future integrate distinct disciplines into studies. A myriad challenges faces science at beginning 2020s. The main aim this overview is assess past achievements current regarding threats such as erosion contamination related different United Nations sustainable development goals (SDGs) including (1) food production, (2) ensure healthy...
It has been shown that soil management under organic farming can enhance carbon, thereby mitigating atmospheric greenhouse gas increases, but until now quantitative evaluations based on long term experiments are scarce, especially Mediterranean conditions. Changes in carbon (SOC) content were examined response to with cover crops a citrus plantation using 21 years of survey data. Soil increase was more apparent 5 after land change suggesting that, for plantations conditions, studies should...
The United Nations Sustainable Development Goal 6 aims for clean water and sanitation all by 2030, through eight subgoals dealing with four themes: (i) quantity availability, (ii) quality, (iii) finding sustainable solutions (iv) policy governance. In this opinion paper, we assess how soils associated land management can help achieve goal, considering at two scales: local soil health healthy landscapes. merging of these viewpoints shows the interlinked importance scales. Soil reflects...
The pivotal role of soil as a resource is not fully appreciated by the general public. Improving education in science represents challenge world where resources are under serious threat. Today's high school students, world's future landowners, agriculturalists, and decision makers, have potential to change society's apathy towards soils issues. This research aimed compare level and/or secondary schools forty-three countries worldwide, together comprising 62% population. Comparisons were made...
Interactions between land and atmosphere directly influence hydrometeorological processes and, therefore, the local climate. However, because of heterogeneity vegetation covers these feedbacks can change over small areas, becoming more complex. This study aims to define how interactions soil moisture temperatures in very water-limited environments. In order do that, water content temperature were continuously monitored with a frequency 30 min two half hydrological years, using capacitance...
Abstract Fifty paired plots under simulated rainfall showed that the use of a cover straw mulch 50% (1 mg ha −1 ) in olive orchards results reduction soil erosion. An economic survey based on interviews shows plantation would cost €174.7 , from which €54.7 is needed for application work, €52.3 purchase cost, and €67.7 transport 20‐kg bales. The 22.5% total income farmers. We found their perception was negative about mulch, as tradition to keep clean any weed or cover, except crop. However,...
Specification and tuning of errors from dynamical models are important issues in data assimilation. In this work, we propose an iterative expectation–maximization (EM) algorithm to estimate the model‐error covariances using classical extended ensemble versions Kalman smoother. We show that, for additive model errors, error covariance converges. also investigate other forms error, such as parametric or multiplicative errors. that Gaussian is able compensate non‐additive sources algorithms...
Shrubland is a Mediterranean biome characterized by densely growing evergreen shrubs adapted to fire events. To date, scientific research has focused on the impact of vegetation soil erosion mainly through control that plant biomass or cover exerts sediment delivery and runoff discharge, being individual species influence hydrological erosional processes not achieved in detail. The objective this determine: i) losses shrubland-covered rangeland at Sierra de Enguera, Spain; ii) how four...
Spain is one of the largest wine producers in world, with Extremadura (south-west Spain) being its second-largest producing region after Castilla La Mancha. Within Extremadura, most traditional and productive viticulture Tierra de Barros, which boasts an annual production 3×106 litres. However, no soil erosion assessment has been undertaken any vineyard to ascertain environmental sustainability. Therefore, Improved Stock Unearthing Method (ISUM) Revised Universal Soil Loss Equation (RUSLE)...
