premii Ad Astra

Asociația Ad Astra anunță lansarea proiectului Premiilor Ad Astra 2022 (link aici), care își propune identificarea și popularizarea modelelor de succes, a rezultatelor excepționale ale cercetătorilor români din țară și din afara ei. Regulamentul de participare se poate gasi aici, iar  pagina de inscriere se poate accesa aici.

Asociatia Ad Astra a cercetatorilor romani lanseaza BAZA DE DATE A CERCETATORILOR ROMANI DIN DIASPORA. Scopul acestei baze de date este aceea de a stimula colaborarea dintre cercetatorii romani de peste hotare dar si cu cercetatorii din Romania. Cercetatorii care doresc sa fie nominalizati in aceasta baza de date sunt rugati sa trimita un email la cristian.presura@gmail.com

Geographical Information Systems Assessment of Development Disparities Among Romanian Regions of Development

New strategies of the European Union, focused directly on regional development or originated from different areas, but leading to changes in this field, had resulted into a set of indices used to monitor the effects of their implementation. Previous studies suggest that flexible systems perform better and could strengthen the administrative capacity of accessing structural and cohesion funds. Our study used the Geographical Information Systems (GIS)

Applications of Principal Component Analysis integrated with GIS

Principal Component Analysis is a statistical instrument able to identify the variables explaining most variation within a sample. When the lines are administrative units within a region, and the input variable account for a specific issue (e.g., level of development etc.), Principal Component Analysis can be used to pinpoint the variables explaining mostly the specific issue. Moreover, if used in conjunction with GIS modeling, the entire approach

Dynamics of the environmental transformation processes during 1990-2006 in Romania reflected by land cover and use changes

The relationship between the natural and anthropic components of territorial systems or complexes of coupled socio-economic and natural systems is changing in time under the effect of socio-economic and political drivers. One way of looking at it is through the changes of land cover and use, which are connected also to the dynamics of the eco-energies during the anthropization process. The aim of this paper is to perform an analysis of long-term

Land cover and land use analysis of urban growth in Romania

While cities appeared and disappeared during the history, and different disciplines, such as ecology and geography attempted to model the process from a systemic perspective, the growth of modern cities, particularly under the form of urban sprawl, is an important phenomenon due to its environmental and socioeconomic impacts. CORINE data allow for analyzing the growth of cities based on the changes in land cover and use. This study aimed to assess

Using Geostatistical Tools to Pinpoint ‘Hotspots’ Showing Biodiversity Threats: Romania as a Case Study

A relatively new concept, 'global change', refined over the last decade to account for the energy - land use - climate change nexus, describes all changes induced by the human species and its activities affecting natural ecosystems and their biodiversity. This chapter reviews several research projects carried out within the national boundaries of Romania, all attempting to pinpoint, explain and predict the impact of 'hotspots' showing potential threats

Tisza river case study

The river Tisza has the largest catchment area among the tributaries of the river Danube. It covers nearly 160 000 km2 and has about 14 million inhabitants. Extreme weather phenomena are already a serious problem in the region. According to the forecasts, the frequency of extreme weather events in the context of droughts and excess water flooding is expected to increase as a result of climate change. In the course of the vulnerability assessment

Changing Microspatial Patterns of Sulfate-Reducing Microorganisms (SRM) during Cycling of Marine Stromatolite Mats

Microspatial arrangements of sulfate-reducing microorganisms (SRM) in surface microbial mats (~1.5 mm) forming open marine stromatolites were investigated. Previous research revealed three different mat types associated with these stromatolites, each with a unique petrographic signature. Here we focused on comparing "non-lithifying" (Type-1) and "lithifying" (Type-2) mats. Our results revealed three major trends: (1) Molecular typing using the dsrA

GIS analysis of wetland cover by NATURA 2000 sites

Geographical Information Systems (GIS) can be used in biological conservation as decision support systems, integrating the spatially referenced CORINE land cover and using data to assess whether natural protected areas cover particular types of ecosystems and/or biogeographical diversity. This study analyzes whether the Natura 2000 sites, which are Special Protection Areas and Special Areas of Conservation declared in Romania cover the diversity

Earthquake hazard impact and urban planning – conclusion and recommendations for further work

This book, which is the second volume in a new series “Environmental hazards”, addresses a topic very much neglected in current research: the role of urban planning in earthquake disaster management. It is not a book about earthquake engineering issues but rather about management issues. Social sciences and arts are often disregarded in earthquake disaster management, the focus being mostly on technical aspects. But the study of the impact is

25 years of sustainability. A critical analysis

25 years have passed since the 'Brundtland Report' defined sustainability as a possibility to equally meet current and future needs. 15 years later, the author of the definition stated that despite of the fact that the definition does not need to be changed, its understanding bettered off during the interval. 25 years later, the present paper takes an in-depth look at the concept and its practical implications. One of the issues being addressed refers
