8 - The German federal state of Mecklenburg-Vorpommern has an outer Baltic coastline of 354 km of which 70% is subject to erosion with an average retreat of 0.34 m/yr. Altogether 135 km of coastline is protected by wooden groynes, beach and dune nourishment, protective dunes and forests, dykes, seawalls and breakwaters at an annual maintenance cost of about 15.5 mio €. During the last decades the sea level rose at a rate of 1.2 mm/yr and an accelerated rate of rise is likely in future. A combined coastal protection and managed re-alignment scheme was implemented in an area of about 1000 ha, which aimed to adapt to the challenges associated with climate change, to reduce costs for coastal protection and to support environmentally sustainable development. The scheme covers 6 km of coastline comprising the seaside resort Markgrafenheide and the wetland and coastal moor Hütelmoor. We provide here the historic background to the area, document the scheme planning and implementation process, and evaluate the approach and success of the scheme. From an implementation and coastal and environmental protection perspective, the project was successful. Despite early public information and participation in planning of the scheme, a strong local opposition and a negative public perception developed which enforced modifications of the scheme.

ISBN 9986058511., p. 856-858The paper presents the variability of long term sea level variability near the Lithuanian sea coast. Longterm (1898-2004) change of sea level in Klaipeda Strait indicates general water rise in the Baltic Sea. The results analysis showed an increase of the sea levels taking place on all time scales at the coastal areas of Lithuania. The regime of long-term sea level is affected by the global climate changes. The great concern should cause the increase in sea level observed in the 20(th) century, which could be directly related to problems of coast erosion, land overflow. - research article
; ;Davulienė, Lina; Journal of coastal research. Lawrence : Coastal Education and Research Foundation, 2012, vol. 28, no. 3., p. 557-569This paper investigates the changes in the long-term hydroclimatic conditions in the SE Baltic Sea, along the Lithuanian coast, on the basis of the monitoring data obtained within a 45-year period (1961–2005). Furthermore, the paper discusses the processes behind those changes. Time series of relevant data along the Lithuanian coast from previous centuries were used to investigate climatic variability and trends. The study finds an increased period of westerly winds during winter. During recent decades, the impact of global climate change on sea-level rise has drawn wide interest, since the coastline changes have ecological, economic, and social impacts on the coastal areas of the Baltic Sea. The analysis of the trends for the Lithuanian coastal zone found results similar to those obtained from global and regional analyses showing increasing sea levels today and in the future.3Scopus© Citations 29WOS© IF 0.496WOS© AIF 2.478Scopus© SNIP 0.501 - conference paper

;Taherisoudejani, Hajar ;Racchetti, Erica ;Celico, FulvioJournal of limnology. Pavia : PagePress, 2018, vol. 77, no. 3., p. 452-465Water quality modeling is increasingly recognized as a useful tool for obtaining valuable information for optimal water quality management. In this study, the free software QUAL2Kw was used to evaluate the impacts of agricultural nitrogen (N) excess on river nitrate (NO 3 -N) concentrations. We explored the possibility to use QUAL2Kw in order to back calculate the exchange of water and N from the groundwater to the Oglio River, northern Italy, which drains a heavily irrigated and fertilized agricultural land. Along the river course water monitoring activities carried out in the dry, summer period revealed steep increases of NO 3 -N in different sectors, by up to 2 orders of magnitude, not explained by any significant point inputs. Such increases suggest the occurrence of large water exchange with nitrate-polluted groundwater and diffuse inputs. In turn, groundwater pollution is due to high N excess in the watershed (~200 kg N ha –1 yr –1 ), flood-based irrigation techniques and soil permeability. The QUAL2Kw model was calibrated using the average of 2 years’ data collected in winter 2010 and 2011 and validated using the data of winter 2012. To minimize the error between simulation results and measured data, the constants of inorganic suspended solid (ISS), ammonium (NH 4 -N), nitrate and organic N were calibrated. The calibration and validation results showed a good correspondence between the calculated and measured values for most of water-quality variables. QUAL2Kw was then run separately with three years’ summer data (2009, 2010 and 2011), and large gaps were found between the measured and predicted values of discharge, electrical conductivity, NO 3 -N and total N. Such gaps are discussed in terms of river-groundwater interactions, limited to the summer period and following irrigation by flooding, rise of the groundwater table and vertical transport of N. The gaps allowed to back calculate the volumes of water and the amount of N exchanged.

;Beconytė, Giedrė ;Gružas, KostasISPRS International journal of geo-informationIn all countries, cities and their suburbs are the most densely populated areas. They are also the places visited by the largest number of tourists and one-day visitors, who inevitably run the risk of becoming victims of crime. It is, therefore, important, not only at national but also at the international level, to know the structure of urban crime and identify urban areas that differ in terms of their criminogenic situation. This requires a geographical approach and regionalisation based on the quantitative data that can offer it. This paper presents the results of a study using big data regarding violent crime, property crime and infringements against public order registered by the police in 2020 in the territories of three major Lithuanian cities and their suburbs (n = 149,239). Events in open spaces were separately addressed. A series of experiments were carried out using several spatial clustering methods. The automatic zoning procedure method that gave the best statistical results was then tested with different combinations of parameters. In each city, seven types of areas of urban crime were identified. Maps of crime areas (regions) were created for each city. The results of the regionalisation have been interpreted from a socio-geographical point of view and conform with previous sociological urban studies. Seven types of areas of crime have been identified, which are present in all the cities studied and, according to a preliminary assessment, roughly correspond to the socio-demographic and urban zones of each city. The maps of crime areas can be applied for crime prevention planning and communication, real estate valuation, strategic urban development planning and other purposes.22WOS© IF 3.4WOS© AIF 4.733Scopus© SNIP 1.194 Publication Arguments for climate change in Lithuaniaconference paper ;Stankūnavičius, Gintautas ;Bukantis, Arūnas ;Rimkus, Egidijus; Stonevičius, EdvinasEMS7/ECAM8 abstracts : 7th EMS annual meeting / 8th ECAM : San Lorenzo de El Escorial, Spain, 01 – 05 October 2007.

Oxford : Elsevier Science, 2012, vol. 50, iss. 8, p. 1125-1137Analysis of Envisat Advanced Synthetic Aperture Radar (ASAR) and Aqua/Terra Moderate Imaging Spectrometer (MODIS) infrared (IR) imagery of coastal upwelling in the southeastern Baltic Sea is presented. It is found that upwelling features are well distinct in the SAR images, and the leading imaging mechanism appears to be the change of the marine atmospheric boundary layer (MABL) stratification over the sea surface temperature (SST) front. This finding is supported by model calculations of the MABL transformation supplemented with the SAR backscatter calculations based on the CMOD4 model. In addition an empirical dependence of the SAR contrasts over the upwelling region on the wind speed and the SST drop is suggested. Finally, surface slicks accumulated in the sea surface current convergence zones generate additional distinct features in SAR imagery. This effect is interpreted within the framework of the coastal current circulation model based on analysis of the SST snapshot.2Scopus© Citations 40WOS© IF 1.183WOS© AIF 3.21Scopus© SNIP 1.041 - research article
; ; ;Pliatsika, Dimitra Alkisti ;Benz, JulianeFriedland, RenéSustainability. Basel : MDPI, 2019, vol. 11, iss. 9, art. no. 2632., p. 1-21Coastal ecosystems are important ecosystem services (ES) suppliers. The degradation of these ecosystems jeopardizes the quality of ES provision. The Biodiversity 2020 Strategy aims at maintaining and restoring ES, although clear guidelines are missing on how to define the state to which ES should be restored. In this respect, synergies between ES assessments and the Water Framework Directive (WFD) exist, but methodological approaches to connect both are lacking. The Marine Ecosystem Services Assessment Tool (MESAT) can overcome this problem. In this study, the tool is applied to semi-open and open coastal water bodies in the Southern Baltic Sea, the Greifswald Bay and Pomeranian Bay. The resulting changes in ES provision confirm the ability of MESAT to be applied in all WFD water body types and a multitude of environmental and anthropogenic gradients. Nevertheless, problems such as data scarcity, spatial extent and historical background of the case studies require adaptations in the assessment process. The spatial extent of all case studies allowed to cover a connected system with a strong environmental (salinity) gradient. Analyzing changes in ES provision in connected systems can help to better understand linkages between ES provision and environmental and anthropogenic stressors as well as trade-offs between ES across water bodies. This information can be further used to support the design of management plans. From the analysis of all MESAT case studies, major factors were identified for the tool to be transfered into a European context, as well as potential problems and solutions. Following the WFD is a strong advantage, which ensures the tool’s transferability to other areas.Scopus© Citations 4WOS© IF 2.576WOS© AIF 4.525Scopus© SNIP 1.165 - research article
; ; Water. Basel : MDPI, 2019, vol. 11, iss. 4, art. no. 676., p. 1-24In this paper we focus on the model setup scheme for medium-size watershed with high resolution, multi-site calibration, and present results on the possible changes of the Minija River in flow, sediment load, total nitrogen (TN), and total phosphorus (TP) load in the near-term (up to 2050) and long-term (up to 2099) in the light of climate change (RCP 4.5 and RCP 8.5 scenarios) under business-as-usual conditions. The SWAT model for the Minija River basin was setup by using the developed Matlab (SWAT-LAB) scripts for a highly customized watershed configuration that addresses the specific needs of the project objective. We performed the watershed delineation by combining sub-basin and hillslope discretization schemes. We defined the HRUs by aggregating the topographic, land use, soil, and administrative unit features of the area. A multisite manual calibration approach was adopted to calibrate and validate the model, achieving good to satisfactory results across different sub-basins of the area for flow, sediments and nutrient loads (TP and TN). After completing the climate change scenario calculations, we found that a net decrease of flow (up to 35%), TN (up to 34%), and TP (up to 50%) loads are projected under both scenarios. Furthermore, we explored the changes in the streamflow composition and provide new insight on the reason of projected nutrient load decrease.4Scopus© Citations 8WOS© IF 2.544WOS© AIF 2.886Scopus© SNIP 1.074 - research article
; ; ;Schumacher, Johanna ;Grunert, RebeccaJournal of coastal conservation. New York : Springer, 2018, vol. 22, iss. 3., p. 549-570Over 350 European Integrated Coastal Zone Management (ICZM) ‘best practice’ case studies are documented in the OURCOAST online public database, to ensure that lessons learned from experiences and practices are shared and improve coastal management practices. However, concrete criteria for ‘best practice’ are missing and a critical evaluation of the success of these case studies did not take place. We present an indicator-based tool and methodology that allows assessing the progress towards sustainability of ICZM measures. An indicator-based tool was applied to 18 thematically different coastal case studies using two different methods: a fast screening and an analysis in-depth assessment. Both methods used help to identify strengths and weaknesses of ICZM and their contribution to sustainable development. However, indicator scores were highly affected by evaluators’ background and perception. The tool is user-friendly and easy to apply, it indicates what progress has made towards sustainability and to which extent targets have been met.Scopus© Citations 20WOS© IF 1.264WOS© AIF 3.153Scopus© SNIP 0.74
