    A wide range of emerging pollutants have been identified in environment: antibiotics, hormones, personal care products, etc. But quite recently a new class of ecological threat has been reported: the presence in waters of abuse drugs coming from human consumption [1,2]. Treatment of wastewaters may remove a portion of these compounds, but sometimes, these treatments are insufficient or nonexistent, residues

    The objectives of the work are to assess the relevance of western Mediterranean wildfires in the context of northern hemisphere countries (North America, Europe and CIS countries) and to evaluate the type of causes and erosion effects using as study case the administrative area of the Valencian Community in Spain. To accomplish the first objective a downscaling procedure using statistical data have been developed based on two detail levels: (1) the most general analysis makes a temporal comparison (1991-2001) according to number of wildfires an burned area between the three northern hemisphere regions (North America, CIS countries and Europe); (2) the second analysis focus exclusively on European countries and the role of Mediterranean regions in such context, also based on number of fires and burned areas. For the second objective a specific analysis of an Administrative area in Eastern Spain has been developed. The methodology has been applied to the Autonomous Region of Valencia ...

    The immediate and subsequent changes induced by a repeated fire on soil structure and organic matter were evaluated under canopy and on bare soil on a set of plots in the Permanent Field Station of La Concordia, Valencia, Spain. In 1995, two fire treatments based on the addition of different biomass amounts were applied. Three plots were burned with high fire intensity (T1), three with moderate intensity (T2), and three unburned plots were used as control (T3). In 2003, plots corresponding to the fire treatments were burned again without addition of extra biomass, giving low fire intensities. In the eight-year interval between fires, plots remained undisturbed. During the first six months after the repeated fire, structural stability shows two trends with differences statistically significant. The higher values are observed under canopy and for T1 on bare soil. Structural stability of T2 is increased around 4% despite the low temperatures reached. Organic matter differences under ca...

    ABSTRACT Desertification is a relatively new term but it is also an old issue in the European Mediterranean zone corroborated by the abundance of historical references highlighting the concern of different cultures on important land degradation processes in the region. The perception of this issue has been changing through time with periods of more environmental sensitivity and awareness alternating with periods of less attention and sensibility. In recent decades, a conceptual evolution has occurred, passing from a vaguely defined but real problem to a progressive assimilation and clarification of the physical and socio-economical processes involved, their factors, causes and also the impacts and consequences. In February 1994, the United Nations Convention to Combat Desertification (UNCCD) came into being. The UNCCD dedicates one of its Annexes to the specific problems of affected countries of the Northern Mediterranean region.

    In this work, the effect of the water erosion processes on a Mediterranean forest soil (Rendzic leptosol) affected by a repeated fire, after eight years of recovering from previous fires of moderate and high intensities occurred in 1995, has been studied. The research was developed in a Permanent Experimental Field Station of La Concordia (Valencia, Spain), during the period 2002-2004, one year before and one year after the repeated fire. Until the incidence of fire in 2003, the evolution during eight years of soil and vegetation characteristics has favoured the decrease of the differences on runoff generation between fire treatments, which were stressed after the 1995 fire. However, differences in runoff yield between burned and unburned plots (remaining the natural occurring vegetation) remain important (72%). Immediately after the repeated, which was of moderate-low intensity, differences between burned and control treatments increased a 20% respect to values previous the fire. T...

    We integrated an index-based attenuation factor/retardation factor (AF/RF) model into a GIS to evaluate the risk of leaching of the most frequently applied herbicides (glyphosate, diuron, diquat, bromacil, simazine, linuron, terbuthylazine, and terbumeton) used in citrus orchards of the Valencia Community, Spain. The GIS-model system was applied to a region of 33,800 ha located near Valencia City. The soil and climate data required by the model were stored in an Arc/Info GIS in which the model algorithms were integrated using the AML programming language. A graphical user interface was developed to facilitate the use of the GIS-model system. The resulting simulation maps indicate that terbumeton, bromacil, and simazine herbicides have the highest risk of leaching because of their high mobility and low K(oc) (32-158 mg l(-1)). The remaining herbicides are strongly adsorbed by clay particles and organic matter, thus minimising the risk of leaching through the soil profile and into groundwater. The obtained ranking of the leaching potential of analysed herbicides is as follows, from highest to lowest risk:…
