Margit Tepner k0848752 Sustainability aspects of biofuels 1. Introduction The literature review will discuss the sustainability aspects of biofuels. Food production will be the main concern as it is the most debated issue, but other aspects, such as land use change and water consumption will be also considered as they are essential aspects in the biofuels sustainability criteria. The review will discuss the viability of biofuels based on the current technologies. Second-generation biofuels are not yet commercially viable and therefore will not be discussed; although they could significantly improve the sustainability of biofuels

population, the diminution in microbial activity is always alarming (Barabasz et al. 2002). Factors influencing soil microflora Soil microorganisms depend on soil for their nutrition, growth and activity. Based on My Agriculture Information Bank (2013) the major soil factors which influence the microbial population, distribution and their activity in the soil are: 1. Natural conditions (including soil fertility, pH, aeritation, temperature, moisture, organic matter, food and energy supply, microbial association and interactions) 2. Cultural practices These factors play a great role in determining not only the number and type of organism but also their activities. Variations in any one or more of these factors may lead to the changes in the activity of the organisms which ultimately affect the soil fertility level. Natural conditions Extreme environments such as high-altitude and highlatitude ecosystems are very sensitive to environmental changes
✔ It helps the farmer to easily supervise and monitor the land and protect his livestock from being hurt or hounded by dangerous wild animals. ✔ With the introduction of intensive farming, farm produce, such as vegetables, fruits, and poultry products have become less expensive. It also aids in solving the worldwide hunger problems to a great extent. This means that common people can now afford a balanced and nutritious diet. ✔ Many opine that organic food can be afforded only by the elite strata of the society. Apart from that, large farming spaces are required to cultivate organic crops using natural manure. However, with the introduction of intensive farming, the space, equipment, and other requirements for farming are less and more economical. ✔ The EPA (Environment Protection Agency) has set certain rules and regulations on how livestock, pesticides, and animal manure are to be maintained. The farmers, who follow these set
Ukraine; even Moldova and Turkmenistan, generally regarded as very poor Soviet republics, were ahead of Ukraine. Ukraine's economy contracted annually between 9.7 and 22.7 percent in 19911996. The country experienced hyperinflation and an exceptionally huge production decline for a country not ravaged by a major war. Official GDP collapsed by almost half from 1990 to 1994, and slow decline continued throughout the decade. Economic growth would not resume again until 2000. The budget deficit was, at 14.4 percent of GDP, exceptionally large. Barter and the use of surrogate moneys and foreign currencies prevailed. Ukraine had introduced a sovereign currency, the Hryvnia, but it was little used. A shadow economy swelled and compensated for an unknown share of the economic collapse. 2001-2008 Between 2001 and 2008, the Ukrainian economy picked up significantly. Many of Ukraine's
many services including transportation and utility companies. The Canadian economy is diverse and highly developed. It is very similar to the American economy, although smaller in size. In the aftermath of World War II, the nation was transformed from a rural economy, based on agriculture, to one based on industry and mining. The nation's economy has been further transformed since the 1970s and services now provide the main economic output. The foundation of the Canadian economy is foreign trade and the United States is by far the nation's largest trade partner. Foreign trade is responsible for about 45 percent of the nation's gross domestic product (GDP). Free trade agreements between the 2 nations have increased trade by eliminating tariffs. Each day approximately US$1 billion worth of goods crosses the U.S.- Canadian border. To understand the scale of U.S.-Canadian trade, it is important to point out that

Estonian Economy Estonians earn about half of the average European income, despite the fact that the economic growth during the recent years has been very fast and the differences have been diminishing. Although the extremely vigorous period of economic reforms is now over, the changes that Estonia is presently going through are far more extensive than those in the developed countries. The Estonian economy is diverse industry and transport, as well as commerce and different branches of services are all equally important. Due to the available natural resources Estonian economy largely relies on the branches related to the forest; Estonian energy sector is based on oil shale, a resource quite rare elsewhere in the world.
