To improve how extreme events and climate variations are managed, there is a need to foster a deeper understanding of their interconnections. Consistent with this objective, this paper describes how precipitation extremes change both temporally and spatially in the Inner Mongolian Plateau (IMP), China and explains their causal factors. The paper refers to data collected from 43 meteorological stations in IMP and describes how precipitation extremes formed and how they influence agriculture. Data gathered and presented in this paper may be useful in understanding the extent to which the IMP is being influenced by global environmental change. This study reveals that the eleven precipitation extremes indices, except the number of precipitation days with over 0.5 mm (R0.5), number of heavy precipitation days (R10), and total precipitation in wet days (PRCPTOT), decreased in the IMP between 1959 and 2014, and most of them were non-significant in temporal. But the dry index has a larger magnitude decreasing trend than that of the wet indices, which can indicate that the dry situation was alleviated in IMP during the study interval. This study also indicated that precipitation extremes have strong relationships with elevation, latitude, and longitude. Atmospheric circulation and topography may be further primary reasons which result in the spatial variation characteristics in precipitation extremes over the IMP. Decreases in precipitation extremes, together with human activities such as livestock improvement and ecological restoration programs, has a positive effect in gross output value of agriculture and animal husbandry in the IMP. The results contribute to a deeper insight on the possible impacts of precipitation extremes and support the development of appropriate adaptation and mitigation strategies to cope with climate extremes. This paper further proposes science-based policies for grassland protection, agriculture, and animal husbandry on the national or regional and herdsman scales.
In the pursuit of eco-efficiency, resilience, and self-sufficiency, sustainable cities focus on long-term environmental goals instead of only short-term economic ones. To do so, many of them rely on servitization, the practice of replacing tangible solutions for intangible ones. Considering steel’s wide range of applications and its pervasive presence, this article’s goal was twofold: Not only to understand how servitization helps sustainable cities, but also the contributions and challenges of the steel present in service-providing. To do so, the criteria of sustainable urban metabolism and circles of sustainability were used to analyze three case studies of servitization: energy, housing, and mobility. The results showed that servitization can provide significant benefits to sustainable cities, while also being able to substantially alter the supply-side dynamics of steelmaking by affecting, most notably, demand. This brought to light how important it is for steelmakers to pay close attention to the service-providing initiatives that may concern their clients and products. Nevertheless, further research is necessary to fully understand all of the effects that servitization can have on all of the commodities involved in its implementation.
Using the method of system dynamics, hypotheses about functioning of the mechanism of energy saving stimulation in buildings and its ecologization tools have been proposed and tested. The results of the survey conducted by domestic and foreign experts were used as the main empirical data for analysis and modeling. The constructed simulation models have allowed to prove the advisability of using multicriteria assessment of energy saving measures effectiveness, as well as to test the recommendations we propose concerning ecologiza- tion of the energy saving process by integrating environmental and social assessments into the rules for making investment decisions. Methods of system dynamics revealed undesirable consequences and points of resistance, which can cause the failure of the proposed intervention.
This comparison study of the implementation of energy-saving projects in buildings was conducted in order to consider the diversity of experiences between Western European countries, which have experience and expertise in this area, and those countries in Eastern Europe that are in the beginning stages. The goal of this paper is to analyze obstacles and incentives for investment in energy conservation in buildings by comparing European countries with a diverse landscape of institutional and economic developments, social-cultural values, and environmental framework conditions in order to understand if these differences are influencing the implementation of energy saving measures and how this can be used to overcome the existing obstacles. The study is based on survey results received from experts in Eastern and Western European countries. The main value of the research is that it offers an overview of the potentials and constraints (barriers) to energy efficiency in Europe, based on data from a sample of western and eastern European countries. Among the most important incentives that were implemented to stimulate energy-saving measures are costs savings and the need to meet regulatory requirements. The main obstacles that still restrict the number of already implemented projects in Europe are a lack of proper financial incentives and that many Eastern countries are still struggling to develop the market of Energy Saving Services (ESS) and to operate better energy waste control systems. The paper concludes with the successful incentives that were implemented to stimulate the energy-saving measures and the main obstacles that still restrict the number of already implemented projects in Europe. Additionally, a set of indicators related to the environmental friendliness and social significance of energy-saving measures was proposed for evaluation of the project results. These were used based on the fact that they may be measured and cater for comparisons. This paper can help improve policy-makers’ selections in order to improve economic instruments appropriate to energy-saving policy objectives and specific national contexts.
