The paper shows the reasons for the intensification of risk-forming processes in Belarus caused by "aging" of existing and the arrangement of new water reservoirs. The shores of new reservoirs located in the territory of Belarus, intensively used in the national economy and densely populated, are actively reprocessed by abrasion, leading to the development of abrasion risk. The length of the abrasion coasts has increased by more than 20 km recently, which undoubtedly has an impact on the surrounding areas, causing loss of land and economic facilities. The goal of the work is to update the regional zoning of the country's territory according to abrasive risk, which should be taken into account in the forecast calculations of the sustainable development of regions based on entirely new principles and assumptions. In this work, we used the data of long-term (covering more than 40-year-long period) field observations of the author over the abrasion process and the results of a science-based analysis. We propose (using the failure tree) an abrasion risk development model and indicators characterizing the abrasion risk, taking into account the global climate change and related warming, affecting the dynamics and extent of the process of destruction and deformation of the coast. Based on a theoretical study of the mechanism for forming the dynamic equilibrium profile of abrasion coasts and the equilibrium coastline, a criterion is suggested that characterizes the stability and development of the equilibrium profile of the coastal slope required for zoning the Belarus territory by abrasion risk. Based on the generalization of the observation results for Belarus water reservoirs and the use of the proposed indicators, we performed zoning of the country’s territory by the abrasion risk, which is of practical importance for making management decisions and designating engineering measures to prevent and mitigate risk in water bodies, as well as minimizing their effects.

In recent years, with the increase of population, the development of urbanization, and the improvement of people’s living standard, people have got an increasingly strong consciousness of environment landscape. While, the global climate change, water shortage and pollution problems which are resulted in the development of social economy.In this article, according to the different traits of waterfront landscape environment, we will analyze the problems of waterfront landscape environment construction, and discuss the design technique of waterfront landscape and the optimization method of landscape environment based on the visual angle of ecology restoration. This can prompt the development of waterfront landscape environment towards the harmony and intergrowth of nature ,ecology and human culture, and this has practical significance for the sustainable development of human and water.

Increase of the Earth’s average surface temperature observed in the last century has affected almost all countries of the world. No state has managed to escape the effects of global warming, and scientists predict that no country will escape a further increase in temperature. However, the highest temperature increases are expected in countries with relatively colder climates. The contribution of low-income developing countries, typically located in some of the hottest geographic areas of the planet, to atmospheric greenhouse gas concentrations is negligible, both in absolute and per capita terms. This article provides a meta-analysis of quantitative estimates of the damage caused by global climate change occurring on the planet since the last century. A rise in temperature has been shown to decrease per capita production in countries with relatively high average annual temperatures, which include most low-income countries. In these countries, the negative effect has long-term nature and operates through several channels, including decrease in agricultural production and labor productivity in sectors more exposed to weather; reduction in capital accumulation and deterioration of human health. Moreover, as evidence shows, in recent years macroeconomic indicators have not become less sensitive to temperature shocks, which points at significant limitations on countries’ adaptation to climate change. Meta-analysis of climate change damage estimates documented in relevant literature will, first, provide an idea of the scale of such estimates and help to assess the current state of knowledge in this area. In addition, a meta-analysis will demonstrate sensitivity of the results of calculations regarding assessment approach, measurement errors or insufficient data, choice of sample, etc. Finally, systematization of climate damage quantitative estimates is highly likely to be of practical importance for authorities and international organizations responsible for developing measures to deal with climate change and mitigate its effects, especially for developing and poor countries, most affected by the negative effects of global warming.

Under the circumstances of global climate change, the El Nino event affects power grid icing by influencing the winter climate characteristics. The response characteristics of the massive power grid icing to El Nino should be of concern. Based on analysis and comparison, this study found that the overall level of response of Hunan power grid icing to El Nino was weak in 2015 winter. Areas with severe power grid icing of Hunan at 2015 El Nino period are mainly distributed at the midwest and southeastern mountainous and surrounding areas, but the maximum ice thickness extremum area range is shrinking. The maximum ice thickness at the El Nino winter enhancing (weakening) follows the trend of El Nino increasing (decreasing). Overall, the maximum ice thickness response characteristics of Hunan power grid at the El Nino period can be divided into four types. This analysis of power grid icing characteristics during El Nino period summarizes the response characteristics of icing and can guide the research of power grid icing and ant-icing countermeasures.
