Afforestation represents a viable solution for the ecological reconstruction of degraded lands, creating medium and long-term premises for using and sustainably developing these lands. The usage of fast-growing woody species in the afforestation of degraded lands include many advantages. The present paper presents data regarding the actual state, biometrics and auxological characteristics, as well as the productive potential of stands from fast-growing species (locust, alders, poplars and willows) from different conditions of degraded lands. Locust (Robinia pseudacacia L.) is one of the fast-growing forest species utilised on degraded lands in Romania. In addition, the species has a recognized importance at a high international level both through its bioproductive potential as well as through its ecological plasticity. All the species that were analysed had a good behviour in relation with the environmental conditions of degraded lands, both from a growing perspective and a health state one. However, this situation is present up to the age of 25-30 years. After this age, stand dryness, thinning, and a decrese of tree growth and quality are affecting the stand’s natural regeneration capacity and ecological diversity.

The inadequate and insufficient treatment of the waste water into a treatment plant endowed with two stage (mechanical and biological, using a treated system with fixed biofilm and a system for treatment and sludge dewatering) and its discharging into a natural stream that supplies a fishing stock, determined an inappropriate aquatic life. The continuous discharge of the water which contains insufficiently oxidized organic and chemical substances (due to non-functionality of the treated biological stage) and the exceeding of the maximum concentration for the quality indicators: ammoniacal nitrogen, CCOCr, CBO5 and detergents decreased the soluted oxygen from the water, the anaerobic biodegradation of the organic matters, ammonia intoxication and the generation of H2S as the lapse of the atmospheric pressure during the precipitations. The effects of the water pollution were manifested in suffocation and mortality of the fishing fauna.

This article reveals the practical experience of using aerial photography by drone in combination with analytical methods of chemical analysis of soil samples for solving problems of adaptive agriculture (application of nitrogen fertilizers) for winter wheat by equipment without precision sowing and GPS. In order to solve this problem, aerial photography was conducted according to the phases of winter wheat growth with simultaneous soil sampling and subsequent agrochemical analysis. Based on the obtained information, thematic maps were created in the GIS package ArcGis and flow charts for the application of nitrogen fertilizers. Additional soil samples were sampled in soil contours where winter wheat was lagging behind in growth, as well as additional general soil analysis and the reasons for the lag of wheat growth were identified. Recommendations on the further use of similar methodological approaches in the territory of Ukraine are given.

The paper aimed to present a different way of identification of a zone of interest for clients of the real estate companies based on the evolution of prices and other essential aspects related to buying a property. For a long time now, they have noticed the need to discover and appreciate the information regarding the real estate domain in a different way. Normally, an agency or private buyer finds information on multiple platforms or other types of advertising, without the possibility of combining all their search criteria in one place but this can change. For this purpose, three types of web maps have been developed based on a data base created in ArcCatalog and ArcMapto help the real estate agencies or individual clients in order to consult as many points of interest as they could. Regarding this aspect, these web maps can ensure a "geographical view" of the details that influence the real estate market by implementing methods of filtering, searching or classifying the points of interest within a certain perimeter. For this paper we used ESRI software’s, for the database and also for processing that information, which led to the expected results.

The city of Cluj-Napoca is located in the central part of Transylvania. It covers an area of 179.5 km2, at an average altitude of 335 m. The climate of Cluj-Napoca is moderately continental, characterized by cold winters, with temperatures often below freezing (0°C or 32°F), and mild or pleasantly warm summers and the precipitation amounts to 595 millimetres. Meteorological data were provided by the meteorological station ADSCON Telemetry of University of Agricultural Sciences and Veterinary Medicine of Cluj-Napoca. In this study it was determined and analysed the annual average temperature, monthly temperature and the minimum and maximum average and monthly precipitation and annual average. Due to the geographical positioning, the city of Cluj-Napoca presents a tendency to increase the temperature and the precipitations are maintained in the normal regime with small seasonal changes.

The paper analyses the behaviour of the soil/subsoil characteristics in the Metropolis of Bucharest under seismic movements with the goal of highlighting the potential damage induced by future strong events. For better understanding the specificity of seismic effects from earthquakes originating in Vrancea region were carried out several national and international research works to assess seismic hazard for Bucharest. Will be presented the last results of the 21st century research programs, with a lot of practical results: several drills in the most critical zones of the city, with hundreds of samples on which were done dynamic tests, static ones and downhole measurements for vp and vs profiles. An analysis of the continuously recordings by accelerometers was done, over the Bucharest area. The paper emphasizes the importance of the accumulated data for understanding the dynamic behaviour of the soil under Bucharest and how it influences the impact of future seismic hazards. Better knowledge of seismic hazard will lead to mitigation of building vulnerability to future seismic movements.

The distribution of the drained lands of Ukraine over the land used areas is investigated, among which the highest economic value is agricultural land. It was found that there are a number of local factors that impede the effective sustainable use of drained land. Among the main factors in the short-term are a short list of crops and non-specialized short crop rotations, and in the long-term - inappropriate use of drained land. The result of such decisions was the reduction of yield potential on drained lands for almost all major crops. In order to eliminate the socio-economic and environmental obstacles to the effective use of drained land for crop production, the following areas of land use in Ukraine have been substantiated: a) cultivation of agricultural crops, traditional for the area where drainage amelioration is conducted, in premise the flax; b) increasing the share of renewable energy sources in the energy balance at both regional and national levels in terms of biomass, bio fuels and waste.

The problem of reuse, recycling and recovery of waste is our concern since at European level, is used, currently a huge amount of materials per year and per person and a significant amount of this materials become waste. The top priority is finding ways to reduce waste where possible, reuse what can be recovered, and recycle more and more amounts of waste. The paper aimed to present some possibilities of valorization of the ash and slag that results from coal (lignite) burning in the large boiler of this thermal power plant in order to achieve the mitigation of the environmental impact. These possibilities consist in experimental work there were achieve within the technological transfer project that is implemented by “Constantin Brancusi” University of Targu Jiu in partnership with industrial partner.
