Biomass energy is often considered problematic because it has many facets and interacts with so many different areas such as land use, forestry, agriculture, animals, and societal factors. The provision and use of biomass energy is a complex issue and is only one part of the problems associated with sustainability of all types of vegetation, which, in turn, is an integral part of ensuring stable socio-economic development. Biomass projects set up to enhance energy availability are also very difficult to quantify because of the many “intangibles” involved. There are no short cuts to trying to obtain a detailed understanding of the successes and failures of projects except by prolonged and repeated local visits and discussions over an extended period by all interested parties. This also requires interaction with diverse groups associated with a project. Generalizations are difficult and can only be derived from individual case studies which have been carefully analysed over long time periods. Nevertheless, answers to the following questions can be very important for replicability. Can generalizations be drawn from such analyses? Can the data be trusted to reflect current knowledge? How replicable, how sustainable and how flexible are the examples, both nationally and internationally?
