“…Ignoring practitioners' realities and attitudes, however, can mean missing important impacts as well as adaptation measures. Studies providing data on the role of adaptation to the climate change indicate that the economic impact tend to be neutral or even positive if adaptation is included (Parsons et al, 2001;Hossel, 2002;Fitzgerald et al, 2009), whereas the impact is negative when no adaptation is included (Leva et al, 1996;Mader et al, 2009;Moran et al, 2009;Walter and Lö pmeier, 2010). Similar results can be observed in cropping studies (Kaiser et al, 1993;Segerson and Dixon, 1999).…”

It is well documented that global warming is unequivocal. Dairy production systems are considered as important sources of greenhouse gas emissions; however, little is known about the sensitivity and vulnerability of these production systems themselves to climate warming. This review brings different aspects of dairy cow production in Central Europe into focus, with a holistic approach to emphasize potential future consequences and challenges arising from climate change. With the current understanding of the effects of climate change, it is expected that yield of forage per hectare will be influenced positively, whereas quality will mainly depend on water availability and soil characteristics. Thus, the botanical composition of future grassland should include species that are able to withstand the changing conditions (e.g. lucerne and bird's foot trefoil). Changes in nutrient concentration of forage plants, elevated heat loads and altered feeding patterns of animals may influence rumen physiology. Several promising nutritional strategies are available to lower potential negative impacts of climate change on dairy cow nutrition and performance. Adjustment of feeding and drinking regimes, diet composition and additive supplementation can contribute to the maintenance of adequate dairy cow nutrition and performance. Provision of adequate shade and cooling will reduce the direct effects of heat stress. As estimated genetic parameters are promising, heat stress tolerance as a functional trait may be included into breeding programmes. Indirect effects of global warming on the health and welfare of animals seem to be more complicated and thus are less predictable. As the epidemiology of certain gastrointestinal nematodes and liver fluke is favourably influenced by increased temperature and humidity, relations between climate change and disease dynamics should be followed closely. Under current conditions, climate change associated economic impacts are estimated to be neutral if some form of adaptation is integrated. Therefore, it is essential to establish and adopt mitigation strategies covering available tools from management, nutrition, health and plant and animal breeding to cope with the future consequences of climate change on dairy farming.Keywords: global warming, cow comfort, heat stress, heat tolerance, functional traits ImplicationsAs a consequence of global warming, drier and hotter summers are expected for Central Europe. Here we discuss multiple interactions between climate change and dairy production in Central Europe in its full complexity, starting from fodder resources to breeding impacts and farm economy. Under current conditions, the impact of climate change on the farm economy is estimated to be neutral if some form of adaptation is integrated. Thus, establishing mitigation and adaptation strategies covering available tools from management, nutrition, health and plant and animal breeding to cope with the future consequences of climate change on dairy farming are essential.-E-mail: Mgauly@gwdg.de 843 ...

“…In Africa, impacts of droughts (1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999) have been shown to induce mortality rates of 20-60% of national herds (12). New models of animal energetics and nutrition (70) have shown that high temperatures put a ceiling on dairy milk yield from feed intake. In the tropics, this ceiling occurs between one-third and one-half of the potential of the modern (Friesians) cow breeds.…”

We review recent research of importance to understanding crop and pasture plant species response to climate change. Topics include plant response to elevated CO2 concentration, interactions with climate change variables and air pollutants, impacts of increased climate variability and frequency of extreme events, the role of weeds and pests, disease and animal health, issues in biodiversity, and vulnerability of soil carbon pools. We critically analyze the links between fundamental knowledge at the plant and plot level and the additional socio-economic variables that determine actual production and trade of food at regional to global scales. We conclude by making recommendations for current and future research needs, with a focus on continued and improved integration of experimental and modeling efforts.

“…Note that the smaller animal production adjustment could be due to the fact that we assumed zero impact of climate change on animal yields. This is based on the assumption that the direct effect of climate change on individual animals would be very small for the next fifty years (Parsons et al 2001). Price adjustments of agricultural commodities tend to reduce the impact of climate change on production.…”

The current paper investigates the medium term economic impact of climate changes on the EU agriculture. The yield change data under climate change scenarios are taken from the BIOMA (Biophysical Models Application) simulation environment. We employ CAPRI modelling framework to identify the EU aggregate economic effects as well as regional impacts. We take into account supply and market price adjustments of the EU agricultural sector as well as technical adaptation of crops to climate change. Overall results indicate an increase in yields and production level in the EU agricultural sector due to the climate change. In general, there are relatively small effects at the EU aggregate. For example, the value of land use and welfare change by approximately between -2% and 0.2%. However, there is a stronger impact at regional level with some stronger effects prevailing particularly in the Central and Northern EU and smaller impacts are observed in Southern Europe. Regional impacts of climate change vary by a factor higher up to 10 relative to the aggregate EU impacts. The price adjustments reduce the response of agricultural sector to climate change in particular with respect to production and income changes. The technical adaption of crops to climate change may result in a change production and land use by a factor between 1.4 and 6 relative to no-adaptation situation.
