In this chapter, an overview will be made of the available biomass resources, primarily in Europe, covering different climate zones from north to south, from arctic over boreal into Mediterranean temperate or subtropical climates. Europe can be seen as an example of what is actually very similar around the globe in Russia, China and North America. Some other climates and biotopes are also covered as comparison, especially the tropics in West Africa (Twenneboah, 2000) and sub-tropics in South Africa. The intention is to give more details than the chapter on the global resources, where the coverage was more general. Much of the data come from Eurostat (2010) andWorld Development Indicators (2011). Concerning specific data on selected crop sources are among others Salisbury and Ross (1992) and Weidow (1998).
