A continuously growing population and their migration to urban centers consequently leads to waste expansion. The rapidly increasing quantities of waste generated in the cities affect way of human life, environment and planet. Hence, the necessity for smarter, safer, and greener places have never been more urgent. The novel technologies, Internet of Things (IoT) particularly, holds the potential to better manage waste and recycling. The IoT-driven waste management systems positively influence achieving the vision of smart green cities. This article analyzes the role of smart and safe IoT-powered waste management system, highlights its benefits, and possibilities of implementation and evaluation. It is expected that the IoT-based waste management system will deal successfully with an increasing amount of diverse types of waste and through the realization of a smart green city vision will resolve numerous problems related to human health and environmental contamination.

The mechanisms by which group-living animals collectively exploit resources, and the role of individuals in group decisions, are central issues for understanding animal distribution patterns. We investigated the extent to which boldness and shyness affect the distribution of social herbivores across vegetation patches, using sheep as a model species. Using an experimental and a theoretical approach, we show that collective choices emerge through the nonlinear dynamics of interactions between individuals, at both short and long distances. Within a range of parameter values derived from the observation of homogeneous groups of each behavioural type, we propose a simple mechanism whereby the same interaction rules can result in different patterns of distribution across patches for bold and shy individuals. We present a mathematical model based on behavioural rules derived from experiments, in which crowding and conspecific attraction affect the probability of entering or leaving patches. Variation in the strength of social attraction is sufficient to account for differences in spatial distribution across patches. The model predicts that resource fragmentation more strongly affects the distribution patterns of shy groups, and suggests that the presence of both bold and shy individuals within groups would result in more flexible behaviour at the population level.

The article is devoted to an overview of the possibilities of modern scientific, technical and technological solutions in achieving the goals of sustainable development, implemented by the UN. The article was prepared on the basis of an analysis of the issues raised during the online discussion “Green Cities and Economies: Solutions from Academia”, held on July 21, 2020 in the framework of the 75th anniversary of the United Nations. The article presents analytical materials that reveal the prospects for using modern scientific and technological achievements in the creation of ecologically clean cities. Possibilities and feasibility of using advanced composite materials and multifunctional nanocoatings in the fight against urban noise have been determined. The advantages of special noise-insulating panels based on composite materials and nanocoatings to reduce the negative effects of city noise are noted. It is concluded that it is necessary to strengthen the participation of the academic community in achieving the goals of sustainable development and the practical use of scientific discoveries in the practice of creating “green” cities.

Abstract. Hydrological heterogeneity is recognized as a fundamental ecosystem attribute in drylands controlling the flux of water and energy through landscapes. Therefore, mosaics of runoff and sediment sinks and source patches are frequently identified in these dry environments. There is a remarkable scarcity of studies about hydrological spatial heterogeneity in restored slopes, where ecological succession and overland flow are interacting. We conducted a field research to study the hydrological role of patches and slopes along an overland flow gradient in three reclaimed slopes coming from mining reclamation in a Mediterranean-continental climate. We found that runoff generation and routing in non-rilled slopes showed a pattern of source and sink areas of runoff. Such hydrological microenvironments were associated to seven vegetation patches (characterized by plant community types and cover). Two types of sink patches were identified: shrub Genista scorpius patches could be considered as a "deep sink", while patches where the graminoids Brachypodium retusum and Lolium perenne dominate were classified as "surface sinks" or "runoff splays". A variety of source patches were also identified spanning from "extreme sources" (Medicago sativa patches; equivalent to bare soil) to "poor sources" (areas scattered by dwarf-shrubs of Thymus vulgaris or herbaceous tussocks of Dactylis glomerata). Finally, we identified the volume of overland flow routing along the slope as a controlling major factor of hydrological diversity: when overland flow increases at the slope scale hydrological diversity diminishes.

Green Cities

The design of a green city integrates with the intention of creating a habitat for people dedicated to the minimization of waste output and pollution. This research aims to determine the moderating effect of the residents’ education level on their intention to recycle. Data collected from a survey on 255 residents in Kuala Lumpur city was analyzed using structural equation modeling. The findings indicate that the realization of green cities is affected by both attitudes towards recycling and subjective norms, which are then moderated by the level of education of the residents.Keywords: Green cities; Attitudes towards recycling; Subjective norms; Education leveleISSN 2398-4295 © 2018.
