Several studies have collected data and observed changes in the phenological phases of several perennial crops in Europe, such as the advance in the start of the growing season of fruit trees (2.3 days/10 years), cherry tree blossom (2.0 days/10 years), and apple tree blossom (2.2 days/10 years), in line with increases of up to 1.4 oC in mean annual air temperature in Germany (Chmielewski et al., 2004), and the advance of apricot and peach tree flowering by 1-3 weeks over the past 30 years for in France (Chuine et al., 2004).
Sowing or planting dates of several agricultural crops have been advanced, by 5 days for potatoes in Finland, 10 days for maize and sugar beet in Germany and 20 days for maize in France (IPCC, 2007).
Assuming that the warming trend will continue, further reductions in the number of days required for flower opening (anthesis) and maturity may be expected for areas in western Europe, where phenological changes are strongly accelerating (ECCE, 2005). However, the rate of the reduction of these phases may gradually decrease with a further increase in temperature due to a reduced efficiency of photosynthesis at high temperatures.
In April 2009 the European Commission presented a White Paper on the framework for adaptation policies and measures to reduce the European Union's vulnerability to the impacts of climate change. The aim is to increase the resilience to climate change of health, property and the productive functions of land, inter alia by improving the management of water resources and ecosystems. More knowledge is needed on climate impact and vulnerability but a considerable amount of information and research already exists which can be shared better through a proposed Clearing House Mechanism. The White Paper stresses the need to mainstream adaptation into existing and new EU policies. A number of Member States have already taken action and several have prepared national adaptation plans. The EU is also developing actions to enhance and finance adaptation in developing countries as part of a new post-2012 global climate agreement expected in Copenhagen (Dec. 2009).
