Introduction. The article considers the problems of using regional-developed territorial methods of waste handling including solid municipal waste for forming regional management systems of waste handling. Issues of expedience of forming secondary resource handling management strategies (with plans of measures on their implementation and target parameters) at regional level are studied. The strategies can become fundamental goals for creation and development of waste treatment infrastructure, efficient mechanism of resource economy management and secondary resource handling in the system of Russian industrial, construction and municipal complex. Solving problems of resource saving and involving secondary resources in economic turnover is of great importance at the modern stage of development of Russia. The aim of the study is to develop a conceptual base for forming regional strategies of the secondary resource handling. Materials and methods. The following materials are used for scientific research: legal certificates, specifications and technical documentation on the waste handling, published materials by domestic and foreign scientific researchers on the given subjects. Methods of scientific research are based on application of comparative and expert kinds of the analysis. Results. The article suggests a methodical approach to creation of a concept of typical project of regional strategy of resource saving and secondary resource turnover, to definition of target regional activity indicators in the given area. Conclusions. Scientific novelty of the research is in integrated system approach to solving the resource saving problems and secondary resource handling at the regional level. Introduction of results of this work will allow providing a scientific and methodical substantiation of creation and development of effective regional management systems in the field of secondary resource handling.

Growing degree-days (GDD, °C·days) are an index of ambient thermal energy that relates directly to an ectotherm’s cumulative metabolism but is rarely used to describe growth and development in fish. We applied GDD to length and maturity data from 416 populations of walleye ( Sander vitreus ) from Ontario and Quebec, Canada (mean annual GDD = 1200 to 2300 °C·days). On average, males matured after they had experienced 6900 °C·days and reached 350 mm total length (L) (n = 77 populations), and females matured after 10 000 °C·days and at 450 mm L (n = 70). Across 143 populations, GDD accounted for up to 96% of the variation in the length of immature walleye but also revealed a twofold difference in growth rate that was indicative of variation in food availability. When applied to data from eight populations in which walleye abundances have changed dramatically over time, GDD revealed a 1.3-fold increase in immature growth rate when abundance was low compared with when it was high. Our results both demonstrate the explanatory power of GDD with respect to fish growth and maturity and inform the development of regional management strategies for walleye.

Population Resilience

The Gulf of Mexico (GoM) is home to the world's largest remaining wild oyster fisheries, but baseline surveys needed to assess habitat condition are recent and may represent an already-shifted reference state. Here, we use prehistoric oysters from archaeological middens to show that oyster size, an indicator of habitat function and population resilience, declined prior to the earliest assessments of reef condition in an area of the GoM previously considered pristine. Stable isotope sclerochronlogy reveals extirpation of colossal oysters occurred through truncated life history and slowed growth. More broadly, our study suggests that management strategies affected by shifting baselines may overestimate resilience and perpetuate practices that risk irreversible decline.

Traffic flow parameters have been found to significantly affect crash risk at micro-levels. If such effects do exist at macro-levels, at least two benefits could be expected: (1) the performance and estimates of planning-based crash models could be improved and (2) useful safety knowledge could be provided for regional traffic management. In this article, a flow-based spatial unit was developed by a graph-cut minimization method, based on which regional management strategies are often applied. The graph-cut method partitioned the central area of Kunshan, China, into multiple sub-regions (i.e. graph-cut unit), considering traffic density homogeneity. Bayesian Poisson lognormal models with conditional autoregressive priors were utilized to examine the safety effects of traffic flow parameters, based on the traditional planning-based units and the flow-based graph-cut units. According to the results, no significant traffic flow effect was found for the traffic analysis zone–based model. Traffic flow parameters resulted in a decreased model performance and potential endogeneity issues for the census tract–based model. However, traffic flow effects were found significant for the graph-cut-based model, with an improved model performance. In general, the safety effects of macro-level traffic flow need to be considered for flow-based units developed for regional management.

Natural Dynamics

Human population density is globally three times higher along the coasts than inland, and thus environmental impacts of human activities are greater in magnitude on coastal ecosystems such as beaches and dunes. Vulnerability assessment (the loss of capacity to return to the original dynamic state after system displacement) is thus necessary to evaluate the conservation status and determine the most relevant disturbance events. Twenty-six sites along 902 km of Gulf of Mexico coastline, varying in conservation status and sedimentary dynamics, were sampled. At each site a vulnerability index (VI) was calculated based on variables that described geomorphological condition, marine influence, aeolian influence, vegetation condition and human effects. Vulnerability was very variable along the coast and only 19% of the sampled locations (mostly in the central Gulf of Mexico) displayed low vulnerability. Cluster analyses of the values assigned to the checklists for each location grouped the studied sites into three, according to their VI values. Low vulnerability locations had abundant sediment supply and low human impact. Locations with medium to high VI were mostly affected by their natural geomorphological and marine features and had medium to intense human activities. Management strategies should consider the observed variability in vulnerability, the natural dynamics of these systems and the role of human activities and interests, in order to achieve adequate policies and establish well-informed priorities for integrated coastal zone management.

This research was conducted in the surrounding areas of a university, Universitas Muhammadiyah Yogyakarta (UMY), which is administratively located in Tamantiro Village, Kasihan District, Bantul Regency, the Special Region of Yogyakarta, Indonesia. It aims to formulate the regional management of the surrounding areas as they have been presenting the indications of urban sprawl. It used a qualitative method with research data obtained from in-depth interviews to 22 informants including governmental agencies (7 informants), academics (6 informants), entrepreneurs (5 informants), and villagers (4 informants). The informants were sampled using purposive sampling method. Data processing and analysis were conducted using qualitative descriptive method, i.e. (1) data reduction, (2) data presentation, and (3) data conclusion. Data validation and reliability tests were conducted using source triangulation method. The results show that the stakeholders proposed various management strategies to improve the positive impacts and, at the same time, reduce the negative impacts of urban sprawl. These management strategies include (1) consistency in implementing spatial planning regulation, (2) spatial synergism in development planning, implementation, and monitoring, (3) assistance to the native people and the migrants, and (4) integration between the university and the village.
