HOW CLIMATE CHANGE CAN INFLUENCE THE AGRICULTURE IN UKRAINE: A REVIEW

Positive Effects ◽

Average Annual Temperature ◽

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.

The purpose of this study is to analyze current global and regional climate changes, as well as a statistical assessment of the factors that cause climate change, on the one hand, and an assessment of the impact of climate parameters on the economy, agriculture and demographic processes using the example of the Yaroslavl region, on the other hand. The study was conducted on the example of the Yaroslavl region and covers the period from 1922 to the present. First of all, the article analyzes the regulatory documents on ecology and climate change. The insufficient attention of federal and local authorities to solving the above problems, the lack of regional strategies to prevent climate change and reduce its negative consequences, which leads to the increased socio-economic risks, is noted. In order to identify factors causing climate change, a correlation and regression analysis was performed. Regression models of the dependence of crop yields on the average annual air temperature and the average annual precipitation were constructed. The statistical base of the study was compiled by the data of the Federal State Statistics Service and the territorial body of the Federal State Statistics Service for the Yaroslavl Region, as well as GISMETEO data. Processing of the research results was carried out in Microsoft Excel and SPSS.During the study, it was found that in the Yaroslavl region there is an increase in average annual and average monthly air temperatures, as well as a slight increase in precipitation, which mainly occurs due to an increase in rainfall in spring and early summer.The anthropogenic factors that cause climate change, namely the burning of fossil fuels, an increase in industrial production, an increase in the number of vehicles, as well as a change in land use and deforestation, are identified and statistically substantiated.As a result of the study, it was found that changes in climatic parameters have an impact on the economy, agriculture and demographic processes, namely: – climate change has a positive effect on agricultural production. According to studies, an increase in average air temperature is a positive factor for the agricultural sector of the Yaroslavl region, as crop yields will increase with increasing air temperature. These trends need to be considered when choosing certain varieties of crops and selecting fertilizers. Increasing the level of management and the transition to more modern technologies will have a greater effect. The efficiency and productivity of agriculture, as well as the food security of the region, will depend on these decisions; – it was found that hydro meteorological factors have a negligible effect on the growth rate of gross regional product and food production; – a statistical study showed that in the Yaroslavl region the effects of climate change on demographic processes and human health are currently insignificant.The findings can be used to develop mechanisms for adaptation to climate change and can serve as a basis for further research in the field of studying the impact of climate change on socio-economic and demographic processes in the Yaroslavl region.

Smart Agriculture ◽

The impact of climate-change disasters poses significant challenges for South Africa, especially for vulnerable rural households. In South Africa, the impact of climate change at the local level, especially in rural areas, is not well known. Rural households are generally poor and lack resources to adapt to and mitigate the impact of climate change, but the extent of their vulnerability is largely not understood. This study looked at the micro-level impact of climate change, evaluated household vulnerability and assessed alternative adaptation strategies in rural areas. The results indicate that climate change will hit crop yields hard and that households with less capital are most vulnerable. These households consist of the elderly and households headed by females. Households that receive remittances or extension services or participate in formal savings schemes in villages are less vulnerable. The results suggest that households need to move towards climate-smart agriculture, which combines adaptation, mitigation and productivity growth.

This paper investigates the impact of climate change on agriculture in the Economic Community of West African States (ECOWAS). To that end, a bio-economic model is built and calibrated on 2004 base year dataset and the potential impact is evaluated on land use and crop production under two representative concentration pathways coupled with three socio-economic scenarios. The findings suggest that land use change may depend on crop types and prevailing future conditions. As of crop production, the results show that paddy rice, oilseeds, sugarcane, cocoa, coffee, and sesame production could experience a decline under both moderate and harsh climate conditions in most cases. Also, doubling crop yields by 2050 could overall mitigate the negative impact of moderate climate change. The magnitude and the direction of the impacts may vary in space and time.

Abstract This study empirically examines the impact of climate change on cereal production in selected lower-middle-income countries with a balanced panel dataset spanning the period 1971-2016. The study uses average annual temperature, average annual rainfall, and CO 2 emissions to measure climate change. Besides this, cultivated land under cereal production, and rural population are also used as the control variables. Second generation unit root tests, i.e., CIPS, and CADF, are used to test the stationarity of the variables. Feasible Generalized Least Square (FGLS) model is used to overcome the issues of cross-sectional dependence, serial correlation, and group-wise heteroscedasticity. The findings show that a rise in the temperature reduces the cereal production in lower-middle-income countries. While other climate variables, i.e., rainfall and CO 2, affect cereal production positively. The sensitivity of long run elasticity has been checked with the help of Driscoll-Kraay standard regression. The adverse effects of temperature on cereal production are likely to pose severe implications for food security. In conclusion, the paper recommends that governments and cereal producers should carry out adaptation activities and programmes to cope with the negative effects of temperature on cereal production.

The article assesses the change in air temperature and precipitation, and also examines the impact of climate change on crop yields in the Republic of Armenia. As a source of information, the actual data of agrometeorological observations of the GEO "Center for Hydrometeorology and Monitoring" of the Ministry of Environment of the Republic of Armenia and the National Statistical Service are used. As a result of the study, it turned out that there are trends towards an increase in the average annual values of air temperature and heat provision of crops (in total temperatures above 10.0 ° C). In the studied area, there are no regular changes in the amount of atmospheric precipitation over the year. The impact of climate change will only worsen and lead to various problems in water industry, agriculture, energy, health and other sectors. In the republic in 2000-2018 are observed of both the gross harvest and agricultural crops yield increase, with the exception of the tobacco crop. However, this does not mean that agricultural crops are not affected by climate change.

Abstract We examines the effects of climate change on the financing cost of heavy-pollution firms using firm-level panel data analysis. The empirical results demonstrate that the annual temperature and precipitation changes can significantly promote the financing costs of heavy-pollution firms, the positive impacts of annual temperature and precipitation changes on the financing costs of large, medium and small heavy-pollution firms has shown a gradual weakening trend with an increase of firm size, and the positive effects of annual temperature and precipitation changes on the financing costs of younger and older heavy-pollution firms has shown a decline trend with an increase of firm age. The evidences confirms that the impact of climate change on the financing costs of heavy-pollution firms exhibit a significant firm size and age discrimination of financing behaviors. Government decision-makers have to identify and optimize the transmission effect of climate change response on financing behavior decisions of heavy-pollution industries, financial institutions alleviate financial conflicts and credit discrimination behaviors and optimize the efficiency of financial resource allocation. Firms’ executives correct climate change strategy, optimize the climate- relevant operation, investment and financing activities, and alleviate unfavorable influences of climate changes for heavy-pollution firms.
