“…Geographical and climate databases (Malone et al, 1998), together with the distribution of parasites obtained from field studies including seasonal patterns (Waller et al, 2004;Altizer et al, 2006) provide a broader picture of changes in the patterns of helminth infections. Retrospective interpretation of available data such as natural phenomena and linked cases (van Dijk et al, 2008;Wu et al, 2008) or creation of climate model predictions (Rausch et al, 2007;Zhou et al, 2008;Fox et al, 2011) are further promising approaches being applied.To achieve more precise epidemiological forecasts, risk maps, extended long-term data sets and improved statistical approaches connecting different information, for example thresholds or tolerances of parasite developmental stages to real environmental conditions, are needed (Weaver et al, 2010). Furthermore, it is necessary to define adequate spatial dimensions for the evaluation of seasonal patterns (Pascual and Dobson, 2005) and, in addition, there is the question which environmental drivers are really relevant for any potential changes in disease risk and which factors affect them (Altizer et al, 2006).…”

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 general, Dongting Lake was divided into east, south, and west sections. Flooding, a major impediment for the control and local elimination of schistosomiasis, frequently occurs in the Lake (Utzinger et al 2005;Zhou et al 2005;Li et al 2007;Wu et al 2008). The warm climate with abundant rainfall, seasonal fluctuations of the water level, and quantities of silt deposition provide an ideal environment for the survival of O. hupensis (Jayawardena et al 1998).…”

Schistosomiasis is a severe public health problem in the Dongting Lake region, and its distribution, prevalence, and intensity of infection are particularly sensitive to environmental changes. In this study, the human and bovine schistosomiasis variations in the Dongting Lake region were studied from 1996 to 2010, and the relationships between schistosomiasis and water level were examined. Furthermore, based on these results, the potential effects of the Three Gorges Dam (TGD) on schistosomiasis were investigated. Results showed an increase in human schistosomiasis and in the scope of seriously affected regions, along with a decrease in bovine schistosomiasis. Human schistosomiasis was negatively correlated with water level during wet season (from May to October), particularly the average water level in October. This finding indicated that the decreasing water level may be highly related to the increasing of human schistosomiasis in the Dongting Lake region. Based on this result and the variation of schistosomiasis before and after the construction and operation of TGD, the impoundment of the Three Gorges reservoir is believed to decrease the water level and increase the contact between people and schistosomiasis. Therefore, the TGD, which is operated by regulating water and scheduling water operations, is not good for the control of human schistosomiasis in the Dongting Lake region. Although the extent of the influence of the TGD on schistosomiasis remains unclear, the influence of the TGD on preventing and controlling schistosomiasis should not be ignored.
