In Romania, agricultural farms represent not only the place where agricultural production is made, as it happens in many European countries, but also the place where live and work almost half of the population of the country (45%); it is also meant to solve the social issues of rural inhabitants. The paper presents the analysis of agricultural farms of Romania as contributors to the development and consolidation of rural farms.The research methodology relies on the analysis, synthesis, representation and interpret...

GIS-Based Local Geomorphological Constraints Assessment (A Case Study: Cluj- Napoca Municipality, Romania). This paper deals with the implications of geomorphological constraints on urban sprawl specific to the new residential suburbs of Cluj-Napoca Municipality (Romania). In many cases, the development and the territorial evolution of the urban residential units are conditioned or restricted by the different landforms and slope processes (e.g. landslides). Cluj-Napoca Municipality area has experienced during rece...

The present paper represents a first for Romania as it aims to empirically analyze the 26 collision cases between military aircrafts and birds registered during 1967 ? 1991. The paper is based solely on the observations made in the above-mentioned period by the Chief of the Meteorological Division within the Romanian Air Force Headquarters between 1990 and 1993 (PhD meteorological engineer and retired commander). This article completes various scientific and statistical studies in the field, which were missing inf...

The habitats and species conservation is one of the most important objectives for the European Union. Loss and habitat fragmentation are the main threats to biodiversity conservation. This study aims to evaluate the impact of the road density on habitats and species richness in Natura 2000 network in Romania. Also, the study looks at how the protected areas distribution and major landscape characteristics influence the transportation network planning. Only Sites of Community Importance (SCIs) as part of the Natura...

Putna?Vrancea Natural Park (38,204 ha) is located in the eastern part of Romania, the upper part of Putna River Basin (Curvature Carpathians). It includes valuable complex forest ecosystems, mountain meadows, also known for the large variety of flora and fauna. Over the past almost thirty years, the study area was subject to diverse natural and man-made environmental stressors which had significantly influenced land use/cover changes with a particular impact on forest-covered areas. The current paper is seeking to...

Multicolored asian ladybird Harmonia axyridis Pall. is a well-known aphid predatory species, of Asian origin. The species is classified taxonomically, at present, in the tribe Coccinellini family Coccinellidae. The species is considerate bivoltine, but may submit up to 5 generations/ year. The main role of the species is its use in biological control. A negative impact on potential benefits that accompany this coccinellid would be predation insects native to the same family. Current status of invasive species is t...

This study aimed to assess the potential of renewable energy resources in Romania and the potential of distorting the energy resources consumption. In this respect, the authors compared the status of Romania with the status of two other countries, Estonia and Croatia, selected as their development of resource use productivity compared with the GDP expressed in euros, with 2010 as the reference year, is the closest to the growth Romania saw in 2000-2015. By considering, as measures, the average GDP in constant pric...

The management of construction waste it is at an early stage in urban areas and lacking in rural areas where this fraction is frequently uncontrolled disposed on public lands. Despite the fact some items of construction waste are considered inert for the environment (soil, concrete) it also contains hazardous items (paint additives, cans, and containers) or recyclables (plastics, metals, wood). Potential recovery of this waste stream is high if it is properly managed. The paper estimates the potential amounts of w...

Drainage of agricultural land is a critical water management tool for the sustainability of cropping productivity systems considering the links between this sustainability and the control of water logging and salinization processes from root zone. Land drainage also provides environmental benefits when it is sustainable designed securing the conservation and improvement of soil resources quality. A key aspect of this problem is the correct determination of distance between drains based on a series of environmental...

At present, there is a lot of interest in finding new energy sources because energy consumption is much above energy production. Geo-thermal energy is part of the category of renewable energies and a non-polluting green energy. Humans have used hot water springs from times immemorial for different purposes. Statistics show that Romania has an outstanding potential in geo-thermal water resources: it ranks third in Europe after Greece and Italy. However, geo-thermal waters are underestimated. The authors of this pap...

Land management and spatial planning are closely linked to the adaptation of water management to climate change impacts. Land management has an influence on the ability of the soil to retain precipitation or flood water and sustainable land use can help to better manage risks related to both increased precipitation/flooding and water scarcity. Land and soil management can also realize significant synergies between climate change adaptation and mitigation. Agriculture as a key form of land use will play a crucial r...
