Abstract:Water pollution has become a global problem and its impact on the health of the human population is growing day by day. This study aims to assess the pollution of the Cibin River (Romania) by a physicochemical analysis. Water samples have been collected from four locations along the Cibin River over a period of 12 months. At this time, there are several commonly used Multiple-Criteria Decision Analysis (MCDA) methods for the assessing the impact of pollutants on the environment. In this research, we used the Analytic Hierarchy Process (AHP) multi-criteria method to evaluate each sampling station's physicochemical parameters. The significant results place the river in the first (sampling stations 1, 2 and 3) and second (sampling stations 4) water quality classes. Another significant result of this work is that the research using GIS software allowed an integrated automatic data collection system and displays interactive results.

The pollution caused by road traffic is a significant problem for society in the 21st century. Climate change and mortality among the population, are increasingly influenced by increasing traffic in urban agglomerations. The present study aims at the multi-criteria analysis of the pollution caused by traffic at several busy intersections in the city of Sibiu, Romania. Classification of intersections was done using the Synchro Studio with Warrants software. Air pollutants, noise, and the number of vehicles in the traffic were taken into account. To analyze these criteria as a whole, the analytical hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) methods were used. A comparative study has been undertaken on the results obtained by applying the two multicriteria methods. The paper aims to provide solutions for the eco-economy of the future.

The Internet has reach half of the population of the planet and in the latest three years more than 700 millions users came on line from the emerging world. Most of them are coming now from the poorer population. This it may be a turning point for their economic development. This paper attempts to outline some possible future developments of the contemporary economy within the new digital transformation and development of internet firms in emerging markets, some of the pluses and minuses, some of the opportunities and threats brought by the expansion of the Internet and information and communication technologies at different levels. We will present some significant aspects about this impact for individuals and for companies especially in Eastern Europe but also around the world. The study intends to deliver also analysis at the level of governmental reactions. Governments have gone through different sentiments that have led to different responses to these technologies. A new revolution that is about to begin it will be grounded on blockchain the technologies that cryptocurrencies are based on. What was initially translated as a threat to governments and central banks can become a solution if it’s deal cautiously.

The Information and Communication Technologies and digital economy are the key factors in the recovery of the EU economy and especially the Romanian economy. Based on its strengths in technology and knowledge, Europe should exploit the full potential of the digital economy. The digital economy and information technologies offer great opportunities for SMEs in the manufacturing and service sectors. Therefore, an ambitious Digital Agenda, providing concrete steps to complete the online single market will be a key to sustainable economic recovery and social development of Europe. The competitive advantage of each country will play an important role in sustaining its future prosperity. Information technologies offer new ways of enhancing sustainable development not only in urban areas but also, to an even greater extent, in rural areas throughout the world. The understanding of what makes them a success or failure, and how much impact they may have in contributing to the wider rural economy is still relatively poorly developed. What is clear, from a wider European perspective, is that these new forms of e-agriculture with ecological entrepreneurialism are growing at a relatively fast rate This paper presents multi-criteria AHP method, (Analytic Hierarchy Process) to assess main technological factors that affect the introduction of new technologies in rural areas.

Abstract:Agriculture is a business sector ideally suited for the application of Geographic Information Systems (GIS) because it is natural resource based, requires the movement, distribution, and/or utilization of large quantities of products, goods, and services, and is increasingly required to record details of its business operations from the field to the marketplace. Nearly all agricultural data has some form of spatial component, and a GIS allows you to visualize information that might otherwise be difficult to interpret. Environment has a major impact on agriculture. In this paper we presented how GIS software can be used to analyze risk factors that influence agricultural production naturally. Natural risk factors were taken into account are: land degradation, flooding, humidity, action on farmland of the wildlife. The conclusions drawn from this paper using GIS allows the adoption of important measures on a short or long time to reduce natural risk factors on agricultural production. The advantage of this model is possibility to bee extended to national, regional and global area.
