Тhe second Аmur complex ichthyological expedition – prerequisites and first results

In 2018–2019 the second Amur ichthyological expedition has been prepared and is being conducted since 2020. The impetus for its organization was a sharp drop in the catches of Pacific salmons in the basin of the Amur River in 2017 and 2018, when after the maximum catch in 2016 (65,2 thousand tons), their catch decreased to 26,9 and 21,6 thousand tons, respectively. This required the adoption of urgent management decisions to preserve their reserves, as well as the expansion of the study of the Amur aquatic biological resources. The expedition has a complex character; the research covers the channel and accessory system of the middle and lower Amur, as well as Khanka Lake. Totally completed: about 5 thousand stations, more than 1,1 thousand hydrobiological samples were taken, about 40 thousand fish were subjected to bioanalysis. New data on the biology of Pacific salmon, smelts, freshwater and sturgeon fish species have been obtained and partially published (70 papers). A number of modern innovative research methods have also been introduced (the use of UAVs and GIS systems to account for Pacific salmon spawners, microchemical analysis of otoliths to assess the effectiveness of their artificial reproduction). The results obtained are of wide practical importance: they are used in the development of measures to regulate the fishing of various aquatic biological resources, including when amending the Fishing Rules.

GIS-based Ecological Risk Assessment on Land Use In Chongqing City, China

Ecological risk assessment (ERA) is a process of predicting the possibility of harmful effects of environmental pollutants on an entire or part of the ecosystem, which is closely connected with the early human health risk assessment. A rational assessment of ecological risks in an urban area can provide great significance for urban landscape pattern optimization, urban ecological risk warning mechanism establishment, and urban ecological environment risk reduction. This study is based on GIS system to assess the ecological risk of land use in Chongqing in 2020, according to the basic theoretical framework and method system of ecological risk assessment. The main process is using remote sensing image data to construct the Ecological Risk Index (ERI) from the perspective of landscape patterns to reflect the potential impact of resource-based urban land use on the ecological environment. In addition, the ArcGIS spatial analysis method was used to evaluate Chongqing's ecological risk. As a result, high-risk area close to the water body just occupied a small part of Chongqing City (around 5%) and this area should be taken into protective measures urgently.

МАЯТНИКОВЫЕ МИГРАЦИОННЫЕ ПОТОКИ БЕЛГОРОДСКОЙ АГЛОМЕРИРОВАННОЙ ТЕРРИТОРИИ

Transport issues in the development of the largest urban agglomerations are associated with commuting labor migrations. Pendulum labor and social migrations are currently one of the main factors affecting the street and road network of the city. The study is aimed at analyzing the migration traffic flows of the city of Belgorod and suburbanized suburban areas based on big data: information on the number and density of the living population depending on the development; the number and density of the working population; the number of low-rise, high-rise buildings and industrial zones, the distribution of jobs depending on the building and the distance from the city center. The study was carried out in a GIS system, taking into account the peculiarities of the networks of operators providing mobile radiotelephone communication services in order to be able to divide the study area of the city of Belgorod into the required sections.

Analysis of River Channel Change Using Remote Sensing Images at Kelantan River Basin

This study presents the utilities of remote sensing technique for analysis of river channel change using remote sensing images at Kelantan River Basin. Understanding river channel change is a key component in developing ecologically friendly and long-term fluvial projects, as well as a way to reduce maintenance costs. The project's study and conclusions will aid in determining how to recognise probable morphological change in river channels. Remote sensing is one of the effective methods for water quality monitoring through image analysis of study area. These tools provide valid means of studying river channel changes. In this study, river channel changes are monitored and quantified by using remote sensing and GIS in Kelantan River. This study focus on four interval years between year 1988 until year 2021 by using Landsat satellite images of 30 m spatial resolution. Landsat Thematic Mapper (TM) 5 images of three different years which are 1988, 1999 and 2010, and Landsat 8 of OLI/TIRS year 2021 were compared. The quantity of accretion and erosion was assessed using parcel-based geoprocessing in a GIS system. The locations are labelled with the year they were created. The area of each year is changing by study period of time for all four interval years 1988, 1999, 2010, and 2021 for research area 1 and 2. The results prove that the river channel in Kelantan is altering, where between 1988 and 2021, the Kelantan River's course has changed significantly. The years 2010 to 2021 are the most severely affected by erosion as a result of the flood in 2014 on the Kelantan River.

Using GIS and SDSS Tools in the Design of a Photovoltaic System for a Built-up Roof

The design and installation of solar panels on the roofs of urban buildings often require consideration of the specific spatial conditions that affect their efficiency. The primary purpose of this work is to develop a procedure for designing and optimizing photovoltaic installations using geomatics methods and specific tools of GIS and CAD systems. The roof of the historic building A2, which is a part of the Poznań University of Technology campus, was selected as the tested object. Solar radiation modelling and determination of suitability zones were performed using SEBE (Solar Energy on Building Envelopes) in QGIS. Possible options for the placement of photovoltaic modules on the roof were simulated with CAD technique in the web-based HelioScope software. The results of the simulation show that the current roof area can generate electrical power of 99.9 MWh/year. The proposed methodology is universal for photovoltaic installations on built-up roofs and can be applied to other buildings and, consequently, the results obtained can be used to improve the content of the solar data urban geoportal.

Residential and Non-Residential Building Damage and Loss Assessment in Georgia

This paper responds to the necessity for the creation of a unified disaster damage and loss assessment method for residential and non-residential buildings in Georgia. The objective of this study is to elaborate on an improved standardized formula for damage assessment in the residential and non-residential sector. The formula provides additional clarity to the various worldwide methodologies and frameworks presently used in the damage assessment of buildings and structures. The paper itself provides four key findings: 1) that each assessment approach and the amount of damage and loss calculated for the residential sector are based on various subjective opinions (non-systematic/standardized damage assessment approaches), derived from the best knowledge from commissions created at the municipal level; 2) a review of global methodologies and frameworks revealed a clear gap in the provision of formulas for calculating economic losses in the residential and non-residential sector; 3) the need for a comprehensive explanation of the unit cost of construction in the UNISDR methodology was identified; and 4) the necessity to collect detailed and specific data for the damage and loss calculation, alongside a requirement for frequent renewals of the integrated database (associated with the need for additional resources) – without which it often leads many countries, including Georgia, to use ineffective methodologies (e.g., HAZUS). Therefore, the study offers a new and original approach for assessing damaged buildings and provides an alternative method to fill the gap in the damage assessment of particular types of buildings and structures. Moreover, the paper proposes a building damage assessment formula that does not require specific databases to be frequently updated or integrated within the GIS system.

The Future Impacts of ESL Events in Euro-Mediterranean Coastal Cities: The Coast-RiskBySea Model to Assess the Potential Economic Damages in Naples, Marseille and Barcelona

In coastal cities, the effects of climate change will cause an increase in the intensity and frequency of extreme sea level (ESL). In this scenario, the application of the Coast-RiskBySea model is proposed to assess the economic impacts of ESL on the built environment in three Euro-Mediterranean coastal cities: Naples, Barcelona, and Marseille. The risk (land use-based) is assessed in the GIS environment as a function of the potential direct and tangible economic damages. The results highlight risk scenarios in all three cities with significant economic damages expected, requiring the implementation of climate mitigation and adaptation measures to reduce the current impacts and limit future ones. The simulations highlight the potential of both remote sensing data and GIS systems to carry out homogeneous environmental analyses over wide areas. The results that were obtained are compared with existing works to verify the reliability of the Coast-RiskBySea model.

Design of Ecological Environment Monitoring System Based on Internet of Things Technology

Because of its high availability, Internet of Things technology is widely used in multipoint ecological environment monitoring and other related fields, which greatly improves the scientificity and accuracy of ecological environment monitoring results. The Internet of Things technology can realize multilevel and omnidirectional environmental monitoring functions by combining GPS systems and GIS systems and, at the same time, can significantly increase the monitoring range of environmental monitoring. On the basis of the Internet of Things monitoring technology, the use of electronic sensors can track and monitor the content and composition of various elements in the environment in real time, thereby reducing the work intensity of environmental monitoring personnel and effectively improving the environment reliability of monitoring results. In this study, we introduce the actual application and direction of the Internet of Things technology in multisite environmental monitoring systems. A water quality pH and temperature sensor monitoring system based on wireless data transmission is designed. Experimental analysis shows that the communication stability of the designed sensor system is relatively good. The average packet loss rate of the network is only 0.87%. The value measured by the designed sensor is very close to the reference value measured by the standard instrument. The average relative error of pH and temperature is 1.56% and 0.77%, respectively, which meets the water quality environmental monitoring standards. It is believed that the use of Internet of Things technology in ecological environment monitoring can effectively solve the problems of low efficiency and low rationality in traditional environmental monitoring methods, thereby fully improving the quality and level of monitoring in ecological environment monitoring.

Modeling wetland restoration scenarios in Gavkhooni International Wetland

One of the challenges for managers is to ensure the long‐term sustainability of wetlands by protecting their ecological values against natural and human pressures. This study has evaluated the past vulnerability status of Gavkhooni International Wetland, Isfahan, Iran, using a combination of GIS and multicriteria spatial decision support systems (MC‐SDSS) processes, to propose restoration scenarios. Three scenarios were developed from criteria established using field studies and expert opinion: (1) wetland restoration to preserve existing water bodies, (2) determination of susceptible regions as habitat replacement for aquatic communities, and (3) a combination of the two previous scenarios. Finally, a map was developed classifying the regions into five categories by area of priority. The northern regions of the wetland were prioritized based on the results of the first and the second scenarios. The third scenario provided the highest opportunity to obtain an optimistic state, that is, normal conditions, for the wetland marginal regions, especially in the central region (between the east and west). In a pessimistic state and optimistic state of the third scenario, almost all parts of the center to the south of the wetland show the lowest priority restoration scenarios. According to the different scenarios, the central regions of the wetland are less affected by agricultural activities and human settlements. In general, the results show that the Gavkhooni Wetland is unstable based on functional, environmental, social and economic conditions. According to the criteria and the MC‐SDSS model, the government can adopt and implement the necessary policies and programs to improve the condition of the wetland.

Extreme weather layer method for implementation of nature-based solutions for climate adaptation: Case study Słupsk

One of the most severe climate risks that is expected to affect all regions is related to stormwater. Climate models, constructed based on long-term trends, show that extreme weather events such as storms, cloudbursts and a large rise in sea level will be significant in the coming decades. Moreover, even the frequency and intensity of “normal” rainfall events, such as microbursts, are expected to be remarkably higher than today in some regions.The efficiency of urban drainage systems is affected by the land use in its whole catchment. In addition to the climate stress, there is ongoing continuous densification of urban space, resulting in more buildings and larger areas being covered with impervious surfaces. Planning decisions today approving such compaction do not consider the impacts beyond the close proximity of the land parcel. As a result, by following the current planning practices, cities are becoming extremely vulnerable to stormwater flooding (flash floods).This study presents a holistic and dynamic planning method – the Extreme Weather Layer (EWL) – that makes it possible to analyse the impact of a single development (e.g. paving a gravel parking lot with asphalt or turning an area of urban greenery into a shopping centre) on the performance of the urban drainage system and therefore on the flooding risk of the whole catchment. The EWL is based on a widely accepted drainage modelling engine coupled with GIS system and other databases which provide spatial information.Thus, the EWL combined with the systemic approach of turning from grey to green infrastructure could be a smart tool for implementing NBS solutions for stormwater management in climate adaptation in urban areas. This smart tool could indicate how much more green infrastructure is needed and which places in the city the mitigative NBS measures would help significantly.

Evaluation and Application of Environmental Value of Rural Land Resources Based on Improved GIS System

As the basis and material source of human production and life, land is an important part of natural resources. With the deepening of the concept of sustainable development, more and more attention has been paid to the sustainable development of land use. Reasonable assessment of land resources and environment is the premise of accelerating agricultural infrastructure construction, optimizing ecological environment construction, and rationally disposing land use structure. This paper proposes an evaluation method of rural land resources and environment based on the improved GIS system and takes Lingshan County as an example, based on the powerful spatial processing and rich spatial query and analysis capabilities of GIS, to analyze the current situation and sustainable development of its land use. It has established a representative and operable evaluation index system, which has certain reference significance for rural land and environmental evaluation.
