AbstractDuring the transition to a market economy, many countries with a planned economy in Central and Eastern Europe face similar challenges when the established socio-economic systems and infrastructures deemed inefficient in a market economy. Also new issues are being raised by the trends of globalization and the vision of sustainable development. In the energy sector the challenges raised by the Kyoto Protocol and its implementation mechanisms are especially interesting, because they are in...

Risk can be defined as the probability that an existing hazard could turn into an accident. It can be evaluated through the potential losses in the manufacturing process or the harmful level of accidents with an impact on human health, caused by unpredictable technical events. Romanian authorities have not found yet a nationwide method for evaluating the risks in the establishments that fall under the scope of the SEVESO Directive. Starting from the potential risk that an accident might occur...

Intensive cereal crops planted on soils from the Western part of Romania determine, annually, significant losses of essential microelements and macronutrients for plant development from the agricultural soil, which lead to the depletion of such lands. Fly ash (FA) resulted from coal combustion at the CET Timisoara power plant, can be used as supplement to an organic fertilizer, such as manure (M) to restore the balance of micro- and macronutrients, important to obtain healthy cereal crops and hi...

Developing countries have seriously low adoption rates of sustainable agricultural practices (SAPs) and there is a need to understand why. This paper reviews 31 past studies focusing on the factors influencing the adoption of SAPs. Using a vote count methodology, SAPs adoption is revealed as a complex set of behaviors which depend on a range of socio-economic, agro-ecological, institutional, informational, psychological factors and perceived attributes. Identified within these six dimensions, ma...
