Self organized critical dynamics of the sustainable development

Meadows, Randers, and Meadows developed a computer model, which studied relations between global resources, production, and consumption. Their model solves a simple system of ordinary differential equations under different scenarios and predicts the future of variables like population, food production, and various measures of pollution and use of resources. Due to the complexities of the observed system, such a simple model can not take into account all significant parameters and therefore cannot be used for accurate long term predictions. Therefore we developed a neural network based model, which we tested with historical data to reproduce the Meadows results. We also used this model to cluster countries based on similarity as measured by the observed variables in an attempt to predict, which characteristics are most significant for their development

How to achieve a sustainable future for Europe?

According to the Lisbon declaration from 2000 the goal of European Union is to become by 2010 the most competitive and dynamic knowledge-driven economy and by 2025 a sustainable knowledge society. The EU however faces some strong challenges on the road toward these goals and is evidently lagging behind both USA and Japan. Our analysis is based on six dimensions of these challenges, including the economic challenge, the demographic challenge, the scientific challenge, the challenge of higher education, the challenge of European governance and identity/system of values, and the environmental/ecotechnological challenge. We argue that if we are to provide a sustainable secure environment and prosperity for next generations, we have to act now at least with developments in particular in the direction of clean, cheap, and renewable energy sources with an emphasis on basic, curiosity driven research which through scientific breakthroughs, is the only realistic solution to solving world's energy requirements. Such an action could for example facilitate the transition from fossil fuels to solar power in a relatively short time of about two decades, and help EU achieve its declared sustainability targets

Effects of Kosovo's energy use scenarios and associated gas emissions on its climate change and sustainable development

Climate change will be the first truly global challenge for sustainability. Energy production and consumption from fossil fuels has central role in respect to climate change, but also to sustainability in general. Because climate change is regionally driven with global consequences and is a result of economic imperatives and social values, it requires a redefinition as to the balance of these outcomes globally and regionally in Kosovo. Kosovo as one of the richest countries with lignite in Europe, with 95-97% of the electric power production from lignite and with 90% of vehicles over 10 years old, represents one of the regions with the greatest ratio of CO2 emissions per unit of GDP, as well as one of the countries with the most polluted atmosphere in Europe. The modelling is carried out regionally for Kosovo for two dynamical systems which are the main emitters of greenhouse gases (CO2, CH4, NOx, etc.) and air pollutants (CO, SO2, dust CHx, etc.): electricity generation and transportation emissions systems, for the time period 2000-2025. Various energy scenarios of the future are shown. We demonstrate that a transition to environmentally compatible sustainable energy use in Kosovo is possible. Implementing the emission reduction policies and introducing new technologies in electrical power production and transportation in Kosovo ensure a sustainable future development in Kosovo, electric power production and transport that become increasingly environmentally compatible.Climate change Greenhouse gases reduction Air pollution Kosovo Sustainable development
