Abstract The present paper focuses on spatial management regulations in order to carry out investment in the field of airport facilities. The construction, upgrades, and maintenance of airports falls within the area of responsibility of local authorities. This task poses a great challenge in terms of organisation and finances. On the one hand, an active airport is a municipal landmark and drives local economic, social and cultural development, and on the other, the scale of investment often exceeds the capabilities of local authorities. The immediate environment of the airport determines its final use and prosperity. The objective of the paper is to review legislation that affects airports and the surrounding communities. The process of urban planning in Lodz and surrounding areas will be presented as a background to the problem of land use management in the vicinity of the airport. This paper seeks to address the following questions: if and how airports have affected urban planning in Lodz, does the land use around the airport prevent the development of Lodz Airport, and how has the situation changed over the time? It can be assumed that as a result of lack of experience, land resources and size of investments on one hand and legislative dissonance and peculiar practices on the other, aviation infrastructure in Lodz is designed to meet temporary needs and is characterised by achieving short-term goals. Cyclical problems are solved in an intermittent manner and involve all the municipal resources, so there’s little left to secure long-term investments.

Most studies assume that road development will improve the economy in the region, as reflected by an increase in Gross Domestic Product (GDP). However, GDP is macro in nature and tends to be biased if we ask who benefits from its increase. To identify whether road development has a positive correlation with the improvement of local economy, hence this study was conducted in a micro context by taking the development of the Soroja Toll Road in Indonesia as a case study. With a length of 10.57 km, connecting Bandung Regency and Bandung City, the newly constructed Soroja Toll Road has a strategic function in supporting activities in the Bandung Metropolitan Area (BMA) and is predicted giving implication on increasing Small and Medium Enterprises (SMEs) profit surrounding its corridor. However, a toll road cannot entirely be seen as a public goods, because not all people have access to this type of infrastructure. Only the users of four-wheeled vehicles and those who can afford to pay the toll charge can access the toll road. This study was aimed at identifying the correlation between the developments of the Soroja Toll Road with the improvement of local economy (SMEs) in its surrounding areas. Based on the analysis result, this study indicates that the presence of the Soroja Toll Road had a bigger positive correlation with the increased profit of medium-sized industries than small-sized industries due to their ability to capture a broader market.

Abstract The present study was undertaken with the databank of dissolved Pb and pH of the aquatic system in the East Kolkata Wetlands, an internationally unique Ramsar Site of Eastern India during a period of twenty years (2000-2019). Our study site is receiving huge amounts of domestic and industrial wastewater from surrounding areas of highly populated metropolitan city of Kolkata. The data on pH exhibits a decreasing trend with the passage of time, which may be attributed to the phenomenon of acidification in which CO2 dissolves with the water and shifts the pH to a lower value. This may result in the dissolution of accumulated Pb in the sediment and transfer the same to the overlying aquatic phase. The increasing trend of dissolved Pb confirms the hypothesis. The significant negative correlation between pH and dissolved Pb (r= -0.7763; p≤0.01) supports the view of the regulatory effect of pH on the dissolved Pb level in the aquatic systems of East Kolkata Wetland.

Abstract The increasing frequency and intensity of climate and weather extremes due to ongoing climate changes can cause major property and infrastructure damage. Mainly representing unforeseen and unavoidable hazards, some environmental and business laws broadly assimilate them as force majeure situations, excepting parties affected by their impact from prior commitments. The present study, debating on the way law courts should broadly address the force majeure clause when objective and accurate evidence is being provided, describes the terms of a legal dispute between the owners of two neighboring buildings which have seriously been damaged by a severe thunderstorm developing over the Bucharest-Otopeni town area, on the 22nd July 2014. Consistent meteorological evidence (weather reports and forecasts, aerological diagrams, radar and satellite images, air-pressure distribution maps, synoptic messages etc.) have been presented to the law court to document, in an unbiased manner, on the extraordinary, external, unforeseen and unavoidable weather event representing the cause of a civil legal dispute. The extent to which the law court may take all these into consideration under the provisions of the force majeure clause is still to be explored.

The Impact

ABSTRACTDespite their importance for mass-balance estimates and the progress in techniques based on optical and thermal satellite imagery, the mapping of debris-covered glacier boundaries remains a challenging task. Manual corrections hamper regular updates. In this study, we present an automatic approach to delineate glacier outlines using interferometrically derived synthetic aperture radar (InSAR) coherence, slope and morphological operations. InSAR coherence detects the temporally decorrelated surface (e.g. glacial extent) irrespective of its surface type and separates it from the highly coherent surrounding areas. We tested the impact of different processing settings, for example resolution, coherence window size and topographic phase removal, on the quality of the generated outlines. We found minor influence of the topographic phase, but a combination of strong multi-looking during interferogram generation and additional averaging during coherence estimation strongly deteriorated the coherence at the glacier edges. We analysed the performance of X-, C- and L- band radar data. The C-band Sentinel-1 data outlined the glacier boundary with the least misclassifications and a type II error of 0.47% compared with Global Land Ice Measurements from Space inventory data. Our study shows the potential of the Sentinel-1 mission together with our automatic processing chain to provide regular updates for land-terminating glaciers on a large scale.

Tropopause fold is the primary mechanism for stratosphere-troposphere exchange (STE) at the midlatitudes. Investigation of the features of tropopause folds over the Tibetan Plateau (TP) is important since the TP is a hotspot in global STE. In this study, we investigated seasonal features of the tropopause fold events over the TP using the 40-year ERA-Interim reanalysis data. The development of a tropopause folding case is specifically examined. The results show that shallow tropopause folds occur mostly in spring, while medium and deep folds occur mostly in winter. The multiyear mean monthly frequency of shallow tropopause folds over the TP reaches its maximum value of about 7% in May and then decreases gradually to its minimum value of 1% in August and increases again since September. Deep folds rarely occur in summer and autumn. Both the seasonal cycle and seasonal distribution of total tropopause folds over the TP are dominated by shallow folds. The relative high-frequency areas of medium and deep folds are located over the southern edge of the TP. The westerly jet movement controls the displacement of the high-frequency folding region over the TP. The region of high-frequency tropopause folds is located in the southern portion of the plateau in spring and moves northward in summer. The jet migrates back to the south in autumn and is located along about 30°N in winter, and the region where folds occur most frequently also shifts southward correspondingly. A medium fold event that occurred on 29 December 2018 is used to demonstrate the evolution of a tropopause fold case over the TP in winter; that is, the folding structure moves from west to east, the tropopause pressure is greater than 320 hPa over the folding region, while it is about 200 hPa in the surrounding areas, and the stratospheric air with high potential vorticity (PV) is transported from the high latitudes to the plateau by meridional winds. A trajectory model result verifies the transport pathway of the air parcels during the intrusion event.
