The Impact

Purpose. As the climate change impacts freshwater and marine ecosystems, and rising ocean temperatures and acidification continue to this moment, our aim was to analyze the literature and summarize information on the development of fish infectious diseases in the light of global warming. Findings. Even a slight increase in temperature affects the life cycle, physiology, behavior, distribution and structure of populations of aquatic bioresources, especially fish. Recent studies show that some infectious diseases of fish spread much faster with increasing temperature. Climate change contributes to pathogens spread in both marine and freshwater areas. In particular, rising water temperatures can expand the range of diseases. Aquatic bioresources have high cumulative mortality from infectious diseases, and pathogens are rapidly progressing, and these phenomena may be powered by climate change, leading to the geographical spread of virulent pathogens to fisheries and aquaculture facilities, threatening much of global production and food security. The article presents data on the impact of climate change and global warming on aquaculture and fisheries. The list of the main pathogens of fish of various etiology in Ukraine, including viral, bacterial and parasitic diseases is presented. The impact of infectious agents on modern aquaculture is described and the main ideas about the possible long-term consequences of climate change for fish farms are given. Practical Value. The review may be useful for specialists in veterinary medicine, epizootology and ichthyopathology. Key words: climate change, infectious diseases of fish, pathogenesis.

<p style="text-align: justify;"><strong>Aim</strong>: The Peruvian region of Ica is an important area of grapevine cultivation, mainly for the production of pisco, the flagship hard drink of Peru. The effects of a changing climate have been assessed using the recorded temperatures of a weather station together with projected climates for the 21<sup>st</sup> century generated under the A1B SRES scenario.</p><p style="text-align: justify;"><strong>Methods and results</strong>: The bioclimatic indices commonly used in grapevine studies have increased in recent years and will continue to rise along the 21<sup>st</sup> century in relation to increasing temperature. In parallel, the phenology of four pisco cultivars (Quebranta, Torontel, Moscatel and Italia) has been experimentally assessed during four consecutive years, first to determine their cumulative growing degree-days and then to project them in past and future climates.</p><p style="text-align: justify;"><strong>Conclusion</strong>: It appears that the cycle lengths of these cultivars have been shortened in recent years and that this tendency will continue all along the 21<sup>st</sup> century.</p><strong>Significance and impact of the study</strong>: Assessing the immediate and future impact of climate change makes it possible to identify potential crop production problems and provides information on adaptation strategies.

The Impact

Researchers disagree about the impact of climate change on conflict among the Maya during the Classic period (ca. 250-900 CE). Some contend that increasing aridity exacerbated conflict, while others have found that increasing temperature ramped up conflict. Here, we report a study in which we sought to resolve this disagreement. We collated annually-resolved conflict and climate data, and then created a Bayesian time-series model for analysing count-based prehistoric and historic data. We carried out three analyses, one covering more or less the whole of the Classic Period (292-900 CE), one focused on the Early Classic (292-600 CE), and one that concentrated on the Late Classic (600-900 CE). Our analyses indicated that climate change likely did impact Classic Maya conflict levels, but our results differed from those of previous studies in two important ways. First, we found that the impact of climate change is only evident during the Late Classic. Second, we found that while increasing summer temperature exacerbated conflict, increasing aridity suppressed it. Thus, our study offers a new, more complex perspective on Classic Maya climate-conflict dynamics. It also has implications for our understanding of other aspects of Classic Maya history and for the debate about the likely impact of the current bout of climate change on conflict levels.

The Impact

The purpose of this work is to review and analyze the main results of modern research on the impact of climate change on the agro-sphere of Ukraine. Results. Analysis of research has shown that the effects of climate change on the agro-sphere are already being felt today and will continue in the future. The observed climate changes in recent decades have already significantly affected the shift in the northern direction of all agro-climatic zones of Europe, including Ukraine. From the point of view of productivity of the agro-sphere of Ukraine, climate change will have both positive and negative consequences. The positives include: improving the conditions of formation and reducing the harvesting time of crop yields; the possibility of effective introduction of late varieties (hybrids), which require more thermal resources; improving the conditions for overwintering crops; increase the efficiency of fertilizer application. Model estimates of the impact of climate change on wheat yields in Ukraine mainly indicate the positive effects of global warming on yields in the medium term, but with an increase in the average annual temperature by 2 ° C above normal, grain yields are expected to decrease. The negative consequences of the impact of climate change on the agrosphere include: increased drought during the growing season; acceleration of humus decomposition in soils; deterioration of soil moisture in the southern regions; deterioration of grain quality and failure to ensure full vernalization of grain; increase in the number of pests, the spread of pathogens of plants and weeds due to favorable conditions for their overwintering; increase in wind and water erosion of the soil caused by an increase in droughts and extreme rainfall; increasing risks of freezing of winter crops due to lack of stable snow cover. Conclusions. Resource-saving agricultural technologies are of particular importance in the context of climate change. They include technologies such as no-till, strip-till, ridge-till, which make it possible to partially store and accumulate mulch on the soil surface, reduce the speed of the surface layer of air and contribute to better preservation of moisture accumulated during the autumn-winter period. And in determining the most effective ways and mechanisms to reduce weather risks for Ukrainian farmers, it is necessary to take into account the world practice of climate-smart technologies.
