On 5-12 July 2009, the second transatlantic Farmer-to-Farmer exchange brought together farmers, foresters, journalists and policy-makers from the United States and Germany to discuss the role of agriculture in future climate policies. On their trip through Ohio and Pennsylvania and ending in Washington DC, the group of 30 participants visited several farms applying climate friendly agricultural practices, as well as biofuel and algae processing facilities. One topic of major concerns was possible ways to off-set GHG emissions by industry through mitigation activities in agriculture. Moreover, participants intensively exchanged knowledge and experiences in different bioenergy applications.
