“…These data suggest that OFMSW could replace EC in the AD at farm-plant level, increasing the farmers' profit. Our conclusions are important as it is becoming a fact that the crop production to support renewable energy production is unsustainable [31] and that OFMSW could be a suitable substitute.…”

“…called fi rst-generation biofuels, have been criticized and debated recently in the scientifi c and non-scientifi c literature (Henke et al, 2005;Patzek et al, 2005;Moore, 2008;Rabbinge, 2008a). Food commodity prices increased sharply between 2004 and the summer of 2008, and many analysts and commentators pinpoint the market development of biofuels as one of the main causes (BBC, 2007;Wroughton, 2008), a key factor allegedly being the subsidized production of biofuels in the European Union and the United States.…”

HAVLÍČKOVÁ, K., WEGER, J., ŠEDIVÁ, J.: Methodology of analysis of biomass potential using GIS in the Czech Republic. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 5, pp. 161-170 This article deals with the issue of a methodology for and analyzing biomass potential in the Czech Republic using a geographic information system. The biomass sources considered include cereal and rape straw, permanent grasslands and forest residuals. The process of assessing biomass potential from agricultural soils is based on assigning yields of individual biomass sources according to the production soil-ecological units (BPEJ) which were created for better agricultural planning in the Czech and Slovak Republics. The analysis of energy crop suitability is based on the evaluation of crop yields related to individual BPEJ's respectively to its component the main soil climate units (HPKJ). To ascertain the production potential of residual biomass (straw) from conventional agriculture, the wheat (grain) yield related to HPKJ was multiplied by the straw coeffi cient. The yield of the permanent grasslands in the main soil climate units was also multiplied by the coeffi cient of dry matter. The me thodo lo gy for the analysis of biomass potential for forest land is based on forest management plans that describe the composition of all forest stands. Data from these forest management plans can be used to determine in detail the potential of the forest biomass in individual periods according to the plan for silvacultural treatment and major harvest of the wood. This detailed analysis is suitable only on the municipality level. On a higher government level, the forest management plan can be used to calculate a coeffi cient that determines the average yield from biomass in the form of forest residuals and in relation to the forest size for specifi c areas or levels of analysis. The energy potential of residual biomass is around 136 PJ from present area of conventional agriculture in the Czech Republic. Biomass consumption in animal production and harvest loses were deducted from this calculation. biomass potential, soil-ecological units, forest residuals, permanent grasslands, straw Today, biomass energy continues to be the main source of energy in many developing nations, particularly in its traditional forms, providing on avera ge 35% of the energy needs of three-guarters of the worlds' population. Biomass covers between 60 and 90% of energy demand in the poorest developing countries. However, modern biomass energy applications are increasing rapidly both in the industrial and developing countries, so that they now account for 20-25% of total biomass energy use. For example, the United States obtains about 4% and Finland and Sweden 20% of their primary energy from biomass (Calle et al., 2007).Biomass features strongly in virtually all the major global energy supply scenarios, as biomass resources are potentially the world largest and most sustainable energy source. The annual bioenergy potential is about 2900 EJ (appr...

“…The use of first-generation biofuels has generated a lot of controversy, mainly due to their impact on global food markets and on food security, especially with regard to the most vulnerable regions of the world economy. This has raised pertinent questions on their potential to replace fossil fuels and the sustainability of their production [4]. Currently, about 1% (14 million hectares) of the world's available arable land is used for the production of biofuels, providing 1% of global transport fuels.…”
