Input Variables

<p>Climate change is one of the largest challenges currently faced by society, with an impact on many systems, such as hydrology. To locally assess this impact, Regional Climate Model (RCM) data are often used as an input for hydrological rainfall-runoff models. However, RCMs are still biased in comparison with the observations. Many methods have been developed to adjust this, but only during the last few years, methods to adjust biases in the variable correlation have become available. This is especially important for hydrological impact assessment, as the hydrological models often need multiple locally correct input variables. In contrast to univariate bias-adjusting methods, the multivariate methods have not yet been thoroughly compared. In this study, two univariate and three multivariate bias-adjusting methods are compared with respect to their performance under climate change conditions. To do this, the methods are calibrated in the late 20<sup>th</sup> century (1970-1989) and validated in the early 21st century (1998-2017), in which the effect of climate change is already visible. The variables adjusted are precipitation, evaporation and temperature, of which the resulting evaporation and precipitation are used as an input for a rainfall-runoff model, to allow for the validation of the methods on discharge. The methods are also evaluated using indices based on the calibrated variables, the temporal structure, and the multivariate correlation. For precipitation, all methods decrease the bias in a comparable manner. However, for many other indices the results differ considerable between the bias-adjusting methods. The multivariate methods often perform worse than the univariate methods, a result that is especially pronounced for temperature and evaporation.</p>

Planning Methods

One of major factors of deterioration in a microclimate of urban development in the conditions of the Rostov region, is degradation of landscapes owing to violation of water balance of the territory. In article the main reasons for violation of water balance which included natural features of the region, a consequence of anthropogenic influence, climatic changes, etc. are considered. Examples from the world practice of urban planning, which show the relevance and effectiveness of compensation for the effects of anthropogenic im-pacts and climate change using planning methods, are given. The experience of the United States, the Nether-lands, Canada and other countries that use water-saving technologies in planning is considered. The rela-tionship of urban planning and the formation of sustainable urban landscapes is shown. The integration of water-saving technologies into the urban environment can be a means of optimizing landscapes and a means of creating unique urban spaces. Reclamation of the urban landscape of low-rise buildings is a necessary step in creating a modern and comfortable urban environment in the conditions of the Rostov region. Meth-ods are proposed to compensate for negative changes in urban landscapes that can be applied at the stage of urban planning. As well as the proposed methods can be applied in the reconstruction of urban low-rise buildings. The considered methods concern not only urban landscapes, but also agricultural landscapes that surround small and medium-sized cities of the Rostov region. In article the author's concept of the organiza-tion of the low housing estate on a basis Urban- facies is submitted. Planning methods of regulation of water balance of the territory on the basis of models the ecological protective of landscapes are offered: an ecolog-ical core, an ecological corridor and an ecological barrier and also analogs from town-planning practice are considered. The reclamation of urban landscapes based on urban planning methods for regulating the water balance of the territory will allow creating unique urban spaces that are resistant to local climatic conditions and the possible consequences of climate change.

Abstract There are two general pathways towards climate change litigation in China: tort-based litigation to hold carbon emitters accountable in civil law, and administrative litigation against the government to demand better climate regulation. While the first pathway is gaining momentum among Chinese scholars, this article argues that legal barriers to applying tort-based rules to climate change should be fairly acknowledged. The article argues that China's legal framework for environmental impact assessment (EIA) provides more openness and flexibility for the resolution of climate change disputes. Therefore, EIA-based climate lawsuits, which challenge environmental authorities for not adequately taking climate change factors into account in decision-making processes, encounter relatively fewer legal barriers, require less radical legal or institutional reform, and have greater potential to maintain existing legal orders. The regulatory effects produced by EIA-based litigation suggest that the scholarship on climate change litigation in China should take such litigation seriously because it could influence both governments and emitters in undertaking more proactive efforts. This China-based study, with a special focus on judicial practice in the largest developing country, will shine a light on China's contribution to transnational climate litigation.
