AbstractThe paper presents the results of the impact of the Tri-City Ring Road on small endorheic catchment basins. Particular attention was paid to pollution discharged from the road to the surface water, as well as changes in hydrological conditions in the vicinity of the road. In the study, surface water samples were analysed in terms of their electrolytic conductivity, pH and content of major minerals. GIS was also used to study transformation of local catchment areas as a result of the road construction, determining their relevance to local conditions of drainage. Moreover, the main directions of transformation of surface waters of the small endorheic wetlands caused by runoff water from the ring road were discovered. Research results have shown a strong influence of the road functioning on surface water properties and changes in hydrological conditions of the studied catchment basins.

AbstractThe methods used to assess the significance of land cover in the vicinity of a road for the mortality of mesopredators are diverse. In assessing the effect of land cover along the road on road causalities, scientists use various buffer sizes, or even no buffer along the road. The aim of this study was to verify how results of land cover effects on the mortality of mesopredators on roads may differ when analyzing various buffer sizes from the road. We assessed road causalities in the Warmian-Masurian voivodeship (Poland) from 3 consecutive years: 2015, 2016, and 2017. The roads were divided into equal sections of 2000 m each with buffer size of radius: 10, 250, 500, and 1000 m. We analyzed the number of road kills of red fox and European badger separately in a generalized linear model, whereas explanatory variables we used land cover types (based on the Corine Land Cover inventory) and traffic volume. Mean annual mortality from road collisions amounts to 2.36% of the red fox population and 3.82% of the European badger population. We found that the buffer size determines the results of the impact of land cover on mesocarnivore mortality on roads. The red fox differed from the European badger in response to land cover depending on the buffer size. The differences we have shown relate in particular to built-up areas. Our results indicate a 500-m buffer as best reflecting the land cover effects in road kills of both species. This was confirmed by model evaluation and a tendency to use or avoid the vicinity of human settlements of the analyzed species. We concluded that buffer size will probably affect mostly the significance of cover types that are spatially correlated with roads, positively or negatively. We suggest that the home range size of given species in local conditions should be assessed before determining the size of the buffer for analysis.

AbstractIt is predicted that climate change will result in the diminution of water resources available both on global and regional scales. Local climate change is harder to observe and therefore, while counteracting its effects, it seems advisable to undertake studies on pertinent regional and local conditions. In this research, our aim was to assess the impact of a river and its catchment on fluctuations in the water availability in a natural lake which belongs to a post-glacial river and lake system. River and lake systems behave most often like a single interacting hydrological unit, and the intensity of water exchange in these systems is quite high, which may cause temporary water losses. This study showed that water in the analyzed river and lake system was exchanged approx. every 66 days, which resulted from the total (horizontal and vertical) water exchange. Also, the management of a catchment area seems to play a crucial role in the local water availability, as demonstrated by this research, where water retention was favoured by wooded and marshy areas. More intensive water retention was observed in a catchment dominated by forests, pastures and wetlands. Wasteland and large differences in the land elevation in the tested catchment are unfavourable to water retention because they intensify soil evaporation and accelerate the water run-off outside of the catchment. Among the actions which should be undertaken in order to counteract water deficiencies in catchment areas, rational use and management of the land resources in the catchment are most often mentioned.

- The project for the south of the Bergamo motorway ring road is the result of a commitment to problems of mobility which Wwf Italy has intensified in recent years. As a result of an initiative taken by the Bergamo Wwf, a master plan was studied for the area in 2007 to identify possible measures to lessen the impact of the road infrastructure by means of forestation and redevelopment with vegetation. The proposal has involved municipal and provincial administrations so that they can learn the contents and concretely implement this green project. As a result of further study of the project conducted by one of the municipalities concerned, the Region of Lombardy granted funding for a contract tender entitled ‘10,000 hectares of new woodland and multi-functional parkland', to be used to implement an initial lot of the project. The work planned and recently started will be completed by the end of 2010 and will constitute the start of a long process of environmental and landscape redevelopment which should be followed by other intervention in the agricultural area of Plis del rio Morla and Rogge.

The Impact

A broad-based approach has been used to assess the impacts of discharges to rivers from 47 surface water severs, with the objective of determining whether such discharges are damaging to stream quality. In order to study as many sites as possible, sampling, laboratory and data analysis techniques were designed to be as simple and rapid as possible. This broad approach was deliberately chosen to contrast with other UK studies in which a small number of sites have been investigated in detail. Three parameters were studied, all of which could reflect the effects of intermittent pollution on stream quality during dry weather. These were the numbers and types of benthic nacroinvertebrates upstream and downstream of the outfalls, the concentrations of metals in algae upstream and downstream of the outfalls, and the concentrations of metals in sediments upstream and downstream of the outfalls. Information relating to the study catchments has been collected from local authorities and by observation at the time of sampling. This information includes catchment areas, land uses and receiving stream quality. Methods used for site selection, sampling, analysis and data interpretation are described. Results show that there is a small but significant fall in biological water quality downstreap of outfalls, but no consistent detectable impact on the concentrations of metals in sediments or algae. The biological effects are compared with the catchment characteristics to identify the factors governing the impact, and upstream water quality is found to be an important factor. Other factors influencing the impact are sewered catchment area and land use.

The road sector is one of the main sources of air emissions in the atmosphere during both construction and operation. The objective of the present paper is a comprehensive evaluation of the impact on air quality during the two main phases of life cycle of roads. In this case study of a motorway project, the emissions of the primary pollutants, CO, NOx, and PM10 are estimated, and the results showed that (i) CO and NOx pollutants released during both phases are comparable, while the emissions of PM10 are more significant in the construction phase; (ii) 85% of PM10 in construction is due to storage, transit on unpaved road, and crushing; (iii) the portals of the tunnel are the sites where there are higher concentrations of pollutants in operation; and (iv) the CO concentrations estimated by the dispersion model are strongly influenced by the topography.

The Impact

Road construction fragments the landscape, reduces connectivity, and drives land use changes. To our knowledge, little is known about the scope and intensity of the effects of cross-border roads on changes in land use. Here, with the land use data products provided by the US Agency for International Development’s SERVIR Mekong project, using the GIS-based spatial analysis to quantitatively analyze and compare the effects of the cross-border road on land use changes within a 30 km buffer area along the Kunming–Bangkok Highway between Laos and Thailand. The results show the following: The greater the distance was from the highway, the smaller were the overall changes in land use within the buffer zone. A comparison of the situation before and after the road was opened in 2013 revealed significant differences in the most influential land use types of agricultural expansion, i.e., from 47.07% to 52.07% (the buffer zone was 1 km). In particular, 57.32% (1381.93 ha) and 40.08% (966.46 ha) of the land occupied by forests had been converted into land for plantation and agriculture, respectively, from 2013 to 2018. The scope of the impact of the operational route on the dynamics of land use was inconsistent. The largest impact before the road became operational was within 4 km of the buffer zone (0.26 to 0.24). Once the road had been opened, the range of its impact was beyond 10 km (0.63 to 0.57). The work here can provide a scientific basis for regional transportation planning and the sustainable use of land resources.

Climate change is one of the main nowadays problem in the world. The politics and strategies for climate change and tools for reduction of greenhouse gas (GHG) emissions and green technologies are created and implemented. Mainly it is focused on energy, transport and construction sectors, which are related and plays a significant role in the roads life cycle. Most of the carbon footprint emissions are generated by transport. The remaining emissions are generated during the road life cycle. Therefore, European and other countries use methods to calculate GHG emissions and evaluate the impact of road construction methods and technologies on the environment. Software tools for calculation GHG emissions are complicated, and it is not entirely clear what GHG emission amounts generate during different stages of road life cycle. Thus, the precision of the obtained results are often dependent on the sources and quantities of data, assumptions, and hypothesis. The use of more accurate and efficient calculation-evaluation methods could let to determine in which stages of road life cycle the largest carbon footprint emissions are generated, what advanced road construction methods and technologies could be used. Also, the road service life could be extended, the consumption of raw materials, repair, and maintenance costs could be reduced. Therefore the time-savings could be improved, and the impact on the environment could be reduced using these GHG calculation-evaluation methods.

One of the most important areas of development in Ukraine is the road sector. It belongs to the strategic sectors of the national economy, and the public road network is a significant component of Ukraine's infrastructure potential. The length and condition of road affects not only the safety and quality, mobility and employment, accessibility of educational and other services, but also causes changes in the temp and flow of capital in Ukraine, and is a necessary prerequisite for recovery competitiveness of the country's economy as a whole. Three international transport corridors pass through Ukraine, which are combined with four national transport corridors. They all pass through the Kyiv region. An urgent problem for Kyiv today is the construction of a Large Ring Road (hereinafter referred to as the "LRR") around Kyiv city, which should relieve the flow of transit transport through the capital of Ukraine, reduce harmful emissions from exhaust gases, and preserve the city roads from being destroyed by excessive vehicles, that are now creating a global city problem.

Road System

Brazil is in a situation of marked degradation in the road system, both in the sense of lacking new road projects and needing repairs to its current infrastructure. It is known that with the demographic increase over the years several positive and negative environmental impacts were caused and that the highways are works that generate great environmental impact. An environmental impact is defined as any change caused to the environment by humans, in turn the negative leads to an ecological imbalance, causing serious damage to the environment. In addition to the great polluting effects of the gases released by car exhaust, there is also the impact of road construction, which implies the withdrawal and transfer of huge amounts of land, deforestation, changes in the form of water runoff, silting of rivers and associated urban expansion. The purpose of this article is to analyze the fundamentals that support the concept, understand the challenges posed and the level of adequacy that reveal the need for legitimacy of the article.
