The National Solid Waste Policy emerged as a guideline for an environmental problem that was observed in Brazilian municipalities: the generation of solid waste combined with a prevalence of landfills. These problems largely became evident in metropolitan regions, which were characterized, among other aspects, by population concentration. Federal Law No. 12,305/2010 explicitly highlighted the issue of metropolitan management. The proposed study aimed to investigate the challenges for achieving the shared management of solid waste in the Metropolitan Region of Natal (RMN). To this end, documentary research and the systematization of secondary databases were undertaken, which enabled diagnostic research into the management of solid waste in the fifteen municipalities that make up the RMN. The study has revealed the difficulties in forming agreements between the municipal entities in the studied spatial profile, thereby influencing the outreach of an integrated management program in the RMN.

Urban Planning And Management

The recognition of metropolitan regions and their growth as a necessary scale of analysis for their integrated management has become a central characteristic of urban planning. The current metropolitan landscape warrants the use of instruments beyond the municipal scale, especially since the economic integration of cities and their development are accentuating urban problems that affect the sustainability of cities. The São Paulo Metropolitan Region (MRSP), one of the world’s megacities, is used as a case study to identify how typologies can contribute to integrated sustainable urban planning and management at the metropolitan level. It applies the territorial analytical typology based on the Driving-Force-Pressure-Situation-Exposure-Effect-Actions (DPSEEA) Environmental Health Matrix to identify the heterogeneity of conditions encountered in large metropolitan regions such as the MRSP. The results show a great variety of environmental and social conditions present in the municipalities of the MRSP that condition the sustainability and health of the urban environment. This typology constitutes a first step to characterize metropolitan regions in socioenvironmental terms using as a conceptual basis a matrix of environmental health indicators, being a precursor in the largest metropolitan region of Brazil.

Abstract This paper focuses on the largely unexamined phenomenon of the developing trans-national suburban area west of Szczecin. Sadly the local communities in this functionally connected area struggle with national planning policies that are unsuitable for the region. The paper examines the impact of those processes on the border region in general and on the localities in particular. The paper investigates the consequences for local narratives and the cohesive development of the Euroregion and what position Polish and German communities took to develop the region, even without the necessary planning support. The region has succeeded in establishing grass-roots planning mechanisms which have helped to create a metropolitan-region working from the bottom up.

The municipality of Marituba, Metropolitan Region of Belém - RMB, has suffered environmental impacts due to irregularities in the landfill operation implemented in 2015, which triggered social impacts perceived by all the population, including neighboring municipalities, such as Ananindeua and Belém Protests were carried out by the Movement Outside the Garbage that is constituted by the dwellings of the surrounding neighborhoods to the place where the embankment is located, of owners of commercial activities linked to the tourism and Non Governmental Organizations that interrupted several times the transit of the main route that interconnects the seven municipalities of the RMB and the entrance of the embankment, in order to draw the attention of the municipal public power to the problems that the population would have been facing ever since. From this, the following questions arose: What social impacts would people be making in these protests? Would such problems be directly related to the activities carried out in the landfill? And finally, what are the actions of the public authority and the company that manages the enterprise in the management of these social impacts? The relevance of this study concerns not only the identification of social impacts considering the fragility of this approach in the Environmental Impact Studies and concomitantly in the Reports of Environmental Impacts, but also, from the point of view of the debate about the licensing process of enterprises of this nature and employment and the need for the joint use of environmental and urban policy instruments, considering that RMB municipalities have not yet used sustainable alternatives for the reduction of solid waste produced in their territories, as well as the reduction of environmental impacts caused by dumps , and in the case of Marituba, of the landfill that operates outside the standards established by the Brazilian Association of Technical Standards - ABNT, which is responsible for the management and treatment of solid waste and the National Policy on Solid Waste - PNRSN.

Understanding pest species composition and their geographic distribution of important spider mites is fundamental and indispensable to establish an integrated pest management program. From a long-term survey during 2008–2017 in mainland China, we found that Tetranychus truncatus was the most frequently sampled Tetranychus spider mite (48.5%), followed by T. pueraricola (21.2%), T. kanzawai (12.5%), T. urticae (red) (5.7%) and T. urticae (green) (4.5%). Among them, T. truncatus was the major mite pest in the north of China. T. kanzawai was the dominant species in the Middle and Lower Reaches of the Yangtze River Region and T. pueraricola was the most important species in the southwest region. Other common and serious pests include Amphitetranychus viennensis (6.8%) and Panonychus citri (3.8%). This pattern was largely different from that in 2002–2004, when T. urticae (green and red) was believed to be the most serious mite pest. The factors involved in the change of species composition are not clear and need more exploration. We suggested that the increasing corn planting range may be partly responsible for the conversion of dominant species from other spider mites to T. truncatus. Further research on the mechanisms underlying the change of dominant species will help develop integrated management strategies.

Abstract This paper identifies hubs of knowledge-based labour in the German urban system from two perspectives: the importance of a metropolitan region as a place and the importance of a metropolitan region as an organisational node. This combination of a network perspective with a territorial perspective enables the identification of hubs. From the functional perspective, hubs are understood as important nodes of national and global networks, established by flows of people, goods, capital and information as well as by organisational and power relations. From the territorial perspective, hubs are understood as spatial clusters of organisations (firms, public authorities, non-governmental organisations). The functional focus of the paper lies on knowledge-based services. Based on data about employment and multi-branch advanced producer service firms, four main types of metropolitan regions are identified: growing knowledge hubs, stagnating knowledge hubs, stagnating knowledge regions and catch-up knowledge regions. The results show an affinity between knowledge-based work and bigger metropolitan regions as well as an east-west divide in the German urban system.

Interactions between cities play a significant role in the development of metropolitan regions. Although these interactions and their role in the urban growth modelling have already been investigated, there is still room for more studies. In this research, in addition to conventional urban growth factors, spatial interactions between the cities (SIBC) are incorporated into urban growth modelling. This causes directional trends in urban growth (DTUG). Therefore, first the DTUG of each city was measured using a developed indicator based on the history of urban growth that was extracted from satellite images and spatial statistics. The SIBC was then estimated by integrating the DTUG of the cities. Finally, the SIBC and other driving forces, including the physical suitability, accessibility and neighbourhood effects, were integrated using a cellular automata-based model. The accuracy of the model in the Tehran metropolitan region was increased by 6.44% after considering the SIBC. The analysis of the DTUG and SIBC in the Tehran metropolitan region during 1991–2000–2007–2014 revealed specific patterns as the spatial interactions intensified over time and usually peaked in the periphery of the central business districts and intense interactions existed between the metropolises and other major cities. These findings could help urban managers with strategic decision-making in the metropolitan regions and adjust the science and practice relation in this field.

Universities are complex organizations, so when implementing an EMS and adopting strategies, methodologies and programs they must involve the entire university system to minimize the negative impacts on the environment and, thus, lead the search for sustainable or carbon neutral organizations. Carbon Footprint was used as an indicator to measure the sustainability effectiveness of the environmental programs implemented and promoted by the EMS-ITM and how they mitigate the emission of GHGs. The calculation of this indicator was developed following ISO 14040-14044 and ISO 14064, for the ITM-Robledo campus and for the period 2015-2017. The results show the relevance and the reduction in the GHG emission levels achieved by the environmental programs studied, especially by the comprehensive solid waste management program, with which the highest levels of mitigation are achieved.

Quality Of Urban Life

<p><strong>Abstract.</strong> The quality of urban life has become one of the most pertinent issues in contemporary times in India. There have been several reports published by government and nongovernmental agencies listing out various dimensions of quality of urban life but in a half-hearted manner as some reports have focused just upon the quality of urban air or some governmental reports talk about Human Development Index. There has hardly been any holistic effort to scale the quality of urban life in terms of economic, social, cultural, environmental and psychological well-being. Unless all these parameters are combined, one cannot furnish the livability index of micro urban spaces within major metropolitan regions. The calculation of livability index thus needs to take into account environmental, socio-economic and mental dimensions. The environment related data has been achieved by extracting NDVI through LANDSAT satellite imagery for the month of May, 2018. NDVI has been used for calculating green spaces index. The data related to socio-economic parameters have been collected through primary and secondary sources of data. The data related to psychological health is gathered through questionnaire survey and personal interviews. Ranking based index calculation has been applied to arrive at a common livability index of select sub spaces in Mumbai Metropolitan Region. The outcomes are very interesting and helpful in comparative analysis of select sub-spaces vis-à-vis quality of life. It has also helped in the identification of stressed sub-regional or micro spaces. Such livability index will be highly useful in regional and urban planning. The research aims at calculating livability index for select sub-regional spaces in Mumbai Metropolitan Region.</p>
