Abstract: The study aims to identify the main gaps in conservation and proposes objectives in the management of protected areas. The physical characteristics of the protected area, the land use, the identification of current pressures and future threats are analyzed. Geomorphological and geological analysis is the component that highlights the correlations between relief and the distribution of habitat types. Among the features that make it unique in the Carpathian landscape, the protected area consists of a very rugged calcareous ridge with calcareous rocky slopes and chasmophytic vegetation, alpine calcareous grass-lands and a habitat of community interest consisting of forests with Larix decidua (the largest larch area in the Romanian Carpathians). The site is also home to a viable population of large carnivores (Ursus arctos, Canis lupus, Lynx lynx).The main current pressures that are also mostly identified as future threats to the site are intensive grazing, the extension of access roads, poaching, creating of conditions for invasive species, reduction of habitat connectivity due to anthropogenic causes, antagonism with domestic animals, and off-road driving of the motor vehicles.Future threats are anticipated due to growing forestry activities, with a negative impact especially by complete deforestation, which is favoured by the restitutio in integrum of forests to the private domain without any conditionality for those that lie within the protected natural areas.Intensive grazing leads to grassland degradation (impoverishment in species, changes in plant association). Among the proposed conservation measures, we mention: strict control of grazing livestock and grazing period, payment of compensation for private forests with high conservation value, limitation of buildings and access roads in the high areas.
Abstract: Biodiversity of our planet is rapidly eliminated, at rates much higher than ever observed in human history. The birds of prey, among others few groups of bird species in Europe, have the highest proportion of threatened and near threatened species per taxonomic group and also, 25% of birds of prey species are experiencing population decline. Today, more than never in our modern life, we have to fight for nature conservation. Our understanding of biological diversity has broadened due to the fact that the use of phylogenies in ecology is increasingly common. If our conservation efforts are directed to maximize the preservation of biodiversity in a broad sense, we have to think beyond species. If we treat the species as evolutionary units, and not like types, our conservation efforts will preserve not only the organism, but the organism capacity to responde to environmental changes. In this paper I aimed to highlight the importance of phylogenetic information in conservation of birds of prey species in Europe through the EDGE approach. This metric has been implemented to prioritise species, beeing the only global initiative to focus on conservation of threatened species with significant amount of unique evolutionary history. Using this approach in conservation, we can be more confident that we will have the potential to preserve more functional trait diversity than expected. The top five birds of prey EDGE species in Europe are: osprey (Pandion haliaetus), the black-winged kite (Elanus caeruleus), the egyptian vulture (Neophron percnopterus), the european honey-buzzard (Pernis apivorus) and the bearded vulture (Gypaetus barbatus), according their EDGE scores.
Abstract: The research presented in this paper was carried out during three years of study (2018-2020) and aimed at studying soil erosion and losses of humus and major macroelements (nitrogen, phosphorus, potassium) based on the precipitation regime that produced runoff on the slope. The research was carried out on a stagnic vertic preluvosoil with a slope of 4%, with a moderate acid reaction and a medium supply of nitrogen and potassium, and weak supply of phosphorus from Balota de Sus area, Dolj County, comprising 3 crops practiced in the area: wheat, corn, alfalfa compared to the field black (uncultivated) and spontaneous vegetation (natural).Following the researches, it was found that the most significant runoff on the slope was recorded in black fallow 471.98 mc/ha and corn 252.62 mc/ha, and the lowest were recorded in wheat 183.43 mc/ha and alfalfa 118.87 mc/ha (25.14% compared to the black fallow).Soil erosion, or soil losses, recorded high values also in the case of corn cultivation 6.84 t/ha (39.42%) and in the case of black fallow 17.35 t/ha (100%).The humus in the soil was lost in the largest quantities also in the corn crop 198.19 kg/ha (40.56%) and black fallow 488.58 kg/ha (100%) and in quite small quantities in the case of alfalfa 89.20 kg/ha (18.25 %).Nutrients in the soil have been lost, both by runoff water on sloping soil and by eroded soil, with higher amounts lost through eroded soil.
Abstract: The aim of this paper is to analyse the changes of Local Labour Markets (LLM) in Spain from 2001 to 2011 of 11 population subgroups (gender, 4 activities, 4 sectors and general population). An algorithmic iterative process with N-1 steps is used to examine commuting data for the 11 subgroups and to trace LLM in both years by maximising the self-containment of jobs (number of jobs occupied by residents of the area and number of residents working in the same area) of the generated areas. Four indexes are calculated for each LLM, and the variation of these four indexes between 2001 and 2011 allows us to classify them as areas that change from areas with a surplus of jobs to deficit areas, or vice versa. The evidence indicates an increase in mobility, difference in the rates of mobility according to subgroup characteristics, and the conversion of surplus markets in employment to deficit markets. These trends give way to wider functional areas and lower levels of self-containment reflected in the length of the journey to work. This impacts quality of life, social cohesion, and the sustainability of the territories.
Abstract: Market access plays an important role in increasing smallholder’s income; however, informal markets are typical in developing countries. Traders often dominate agricultural markets. In Vietnam aquaculture, collectors are important actors and act as an intermediary in linking farmers and buyers. This research aimed to explore and analysis the functions and the dominance of collectors in linking with smallholder fish farmers in Tam Giang lagoon, central Vietnam. The qualitative research is applied through 55 semi-structured interviews including smallholder fish farmers, collectors, wholesalers, retailers, officers of local government and second information from statistic data and reports. The research findings showed that linking of smallholder fish farmers to output market has dependence on collectors while all aquatic products have to pass on collectors before distributing to next buyers. Collectors always have strategies to maintain the relationship with smallholders and they always have an advantage status in aquaculture value chain. Collectors are also considered as a barrier of smallholder farmers to access potential marketing channels. Informal transaction and trust are characterized in the interaction between collectors and smallholders.
