Summary of findings Gustav Paulig Ltd., Joh. Johannson Kaffe AS, Löfbergs Stakeholders in the coffee value chains in all four countries Lila AB, Neumann Gruppe GmbH, Tchibo GmbH, already perceive changes in coffee production that can Fondazione Giuseppe e Pericle Lavazza Onlus, and the be linked with changing climate conditions, although Deutsche Gesellschaft für Internationale Zusammenarbeit only two of the countries can count on specific climate (GIZ) on behalf of German Federal Ministry for Economic predictions. In Guatemala and Brazil, where scientific Cooperation and Development (BMZ) are implementing a institutions provide suitability maps, large changes in the supra regional Development Partnership with a focus on distribution of the coffee are expected over the next forty coffee and climate change. The objective of the initiative years with a smaller net loss in the total area suitable for for coffee and climate is that producers and service coffee production. These predictions serve very well to providers along selected green coffee supply chains in start the development of adequate adaptation strategies. key coffee regions have access to adequate knowledge In Vietnam climate impact scenarios, are accessible and instruments that enable them to apply and finance for agriculture, but there are no estimates of impacts effective climate change adaption and mitigation strategies. on Robusta cultivation, while Vietnam is the world’s In order to be better prepared for the impacts of climate largest Robusta producer. Nevertheless, the institutional change, scientific research on a regional basis is necessary. framework in Vietnam appears to be very supportive Therefore short country portfolios on coffee and climate of climate change initiatives and representatives at change had been developed for the four pilot countries governmental and academic institutions are highly Brazil, Vietnam, Tanzania and Guatemala. motivated to cooperate. In Tanzania climate change data based on international research are generally available, For the present work several stakeholders at international but coffee impact scenarios only exist for the neighbouring level and national level in the four pilot countries were countries of Kenya and Uganda. Also the institutional contacted (see Annex I). They provided information on the framework is rather weak. Consequently, the coffee and national coffee sector, climate change data and impact climate initiative should invest in building institutional scenarios as well as research studies on climate change capacities in Tanzania and also in Vietnam as well as in impacts on coffee production and trade, so far available. generating baseline information. All available information was studied and systematised Without question, all four pilot countries
