Energy Supply Systems

70% of the population of Ukraine lives in cities. Electric energy supply of cities with dense buildings is provided mainly from centralized generation sources: TPPs, CHPs, NPPs, RES, and heat energy - from CHPs and gas boilers. Possibilities of energy self-sufficiency of Ukrainian cities based on use of alternative and local energy sources are analyzed. There is a global trend of increasing share of RES in cities energy supply, especially in cities and districts with cottage development. Providing cities with their own energy resources can be achieved through integrated use of renewable and local sources. Production of electricity from renewable sources in terms of return on investment EROI and normalized energy cost over life cycle of LCOE generation source is close to traditional sources indicators. Examples of RES usage to meet energy needs of houses and settlements in Europe are given. High cost of renewable energy stimulates development of this area in Ukraine. Efficiency of renewable and local sources usage in buildings is achieved only with simultaneous introduction of energy saving measures - insulation of buildings, introduction of energy control systems.

Qualitative Changes

The results of research on the key area "Sestra River" (229 km2), located within St. Petersburg and the Leningrad region, are considered. The study of recreational development of the territory was carried out in 2009-2010 and 2019-2020 using field surveys, analysis of topographic maps of different times and satellite images. Maps of recreational development of the model territory for the 1960s, 2010, and 2020 were compiled. In 2010, 16 types of land use were identified as the territories that have a recreational function as the main or additional one; this number does not include complexes with a primary residential and additional recreational function (cottage settlements, etc.). In 2020, 17 types of such territories were identified. Comparison of maps of recreational development revealed qualitative changes in various recreational complexes in 2010-2020: collective gardens, social dachas, year-round and seasonal complexes with low-rise buildings, cultural entertainment and sports-entertainment centers, etc. Over 10 years, the share of the area of recreational and residential-recreational complexes at the "Sestra River" key area has increased from 4.8 to 5.2 %. Recreational activities are being diversified. While preserving its traditional types, new types appear: farms with a recreational function, rope parks, entertainment complexes, etc. Recreational complexes for year-round use with low-rise buildings on forest land are being created. Cottage development becomes comparable to recreational development of the territory. A significant part of the houses in cottage and dacha settlements and collective gardens are used as permanent residence; at the same time, their recreational function becomes additional. Increasing the area of cottage settlements on forest land reduces the availability of landscapes of high recreational value for the population. Recreational transformation of territories, which is inseparable from suburbanization in the zones of influence of major cities, is rapidly changing the landscapes.

Mammal Diversity

Changes in small mammal abundance and habitat caused by shoreline cottage development in central Ontario were studied in the summers of 1978 and 1979. This development significantly altered the vegetation composition and structure in the vicinity of cottages. These alterations, in turn, had an impact on small mammal abundance. These animals were classified in three response categories: tolerant (existing, at some level, regardless of degree of development), intolerant (extirpated at high levels of development), and indifferent to development. Tolerant species were the eastern chipmunk (Tamias striatus), short-tailed shrew (Blarina brevicauda), and deer mouse (Peromyscus maniculatus); intolerant species were the masked shrew (Sorex cinereus), red-backed vole (Clethrionomys gapperi), and woodland jumping mouse (Napeozapus insignis). The red squirrel (Tamiasciurus hudsonicus) was indifferent to development. Small mammal diversity was highest on mixed shorelines at moderate levels of development. Species diversity appeared to respond positively to vegetative composition, edge effect, and irregularity of habitat. These characteristics were all dependent on the level of cottage development.

The Impact

Several coastal embayments of eastern Georgian Bay show signs of water-quality impairment thought to be caused by human activities. Here, we evaluate the ability of the Lakeshore Capacity Model (LCM), developed for Precambrian Shield lakes, to assess the impact of cottage development on the trophic status of ten Georgian Bay embayments. The LCM could only be applied to eight embayments due to the large size and complexity of two watersheds and produced unacceptably high estimates of mean seasonal total phosphorus concentrations ([TP]; i.e., exceeded 20% of measured values for five of eight embayments); accuracy of [TP] estimates could not be improved by accounting for internal phosphorus loading. We developed an additional model, the Anthro-Geomorphic Model (AGM), which uses building density and basin morphometry as variables. Estimates of [TP] for the AGM were within 20% of measured values for all sites. Compared with other aquatic systems, coastal embayments of Georgian Bay have significantly higher chlorophyll a concentrations per unit [TP]; we suggest that the TP–chlorophyll relationship presented in this study be used to estimate productivity in these systems.
