This is a sample of some of the great mixed cropping, agroforestry and biofuels oral presentations at Tropentag Strategies to Use Biofuel Value Chain Potential in Sub-saharan Africa to Respond to Global Change Enhancing Low-productivity Farming in Tanzania and Linking to SMEs – Stefan Sieber Some of the most significant global drivers stem from energy demands. This study examined new strategies to improve value chains and biofuel potential in order to provide communities in Sub-Saharan Africa with multiple energy services. The study took place in Tanzania, however global applications of the findings was one of the overall objectives. One way to improve energy demands in developing countries is though linking small scale farmers with small- to medium-scale enterprises. This research project worked with stakeholders in order to develop feasible strategies to maximize profit. The output from this collaborative effort was the development of global scenarios (applications in other countries), biomass production, consumption patterns, as well as a participatory biomass value chain. The objective of the research was to conduct a sustainability impact analysis and an information system for policy/decision support. In order to obtain the relevant information the research team conducted stakeholder workshops with national policy makers and farmers. The sustainability impact system was designed by the use of indicators for self-assessment and key questions relevant to the requirements of value chains. For instance, is the community able to cope with capacity building? Do they have market access? A total of 60 research questions were developed. The research results were funneled into an information system that is now accessible by stakeholders at www.better-is.com. The information is also available in Kiswahili.
