The significant challenges of climate change and energy security give reasons for this thesis dealing with the analysis of climate change and energy vulnerabilities in the Austrian bread value chain. The literature review shows that potential future challenges in the next 20 years might include increasing temperatures, changes in precipitation, increasing worldwide energy demand, etc. ? to name just a few. Owing to the dynamic elements of vulnerability, no overall vulnerability statement can be given. Despite the high climate change sensitivity, the Austrian arable farming sector generally faces a low to medium vulnerability, but high vulnerability in Eastern Austria concerning water supply. Winter wheat in particular might benefit slightly as per a regional study. However, the sector is highly vulnerable considering a possible increase in extreme weather events and vulnerable to the appearence of neobiota, pests and diseases. Regarding energy, the baking process is the most energy intensive step, followed by the production of fertilizers used in the agricultural sector, and fossil fuels play a major role in the value chain. However, more research is needed especially also on adaptive capacity to give a more explicit statement on the vulnerabilities in the chain. Qualitative interviews among value chain?s representatives and actors reveal estimations and perceptions on future challenges, ranging, amongst others, from yearly yield fluctuations to possibly increasing energy prices, and also personal uncertainties in projecting future changes are expressed, as well as possible measures to adapt. Possible adaptation measures can include the breeding of new cultivars, changes in the agricultural farming methods, the reduction of energy consumption, etc. However, I recommend an evaluation of potential measures including different criteria ? e.g. the potential of measures to mitigate climate change, to promote resilience and the justice of measures.
