Growth in the world economy requires an increase in global energy demand. And oil remained the world?s leading fuel, accounting for a third of global energy consumption (BP?s Energy Outlook, 2017 edition). However, the amount of conventional light oils is rapidly declining due to long-term and largely-scale extraction. Therefore, to relieve the pressure exerted on conventional oil resources, it is imperative to efficiently develop and utilize those unconventional oil reserves. Heavy oil is considered as an alterna...

Agricultural production is expected to increase in the world, which will be determined by the growing population and the rising demand for food, feed, fibre and energy. However, an increase in agricultural output could result in an increase in greenhouse gas (GHG) emissions from the agricultural sector. In order to avoid it, emissions have to be ?decoupled? from agricultural production, i.e. it is necessary to decrease the GHG emissions per unit of agricultural production. This is particularly important for Latvia...

More than half of the world population lives in cities. In 2030, 80% of the world population will live in urban areas, according to United Nations migration forecasts. People who are living in cities are exposed to air pollution. The concentration of air pollution is increased by traffic intensity. Increasing traffic intensity increases the number of automobile congestion in large cities. Therefore, there is a need to implement the measures for reducing air pollution in surroundings. Scientific studies show that e...
