Shoreline Evolution and Environmental Changes at the NW Area of the Gulf of Gela (Sicily, Italy)

2021

Coastal areas are among the most biologically productive, dynamic and valued ecosystems on Earth. They are subject to changes that greatly vary in scale, time and duration and to additional pressures resulting from anthropogenic activities. The aim of this work was to investigate the shoreline evolution and the main environmental changes of the coastal stretch between the towns of Licata and Gela (in the Gulf of Gela, Sicily, Italy). The methodology used in this work included the analysis of: (i) shoreline changes over the long- and medium-term periods (1955–2019 and 1989–2019, respectively), (ii) dune system fragmentation and (iii) the impact of coastal structures (harbours and breakwaters…

Coupling a hydro-maritime model and remotely sensed techniques to assess the shoreline positioning uncertainty: the Marsala coast study case

2010

The severe erosion phenomena affecting the Mediterranean coasts are strictly related to geophysical characteristics and socio-economic pressures. This suggests the need of monitoring and modelling the phenomenon in order to quantify its strength. In fact, the shoreline position, as well as its temporal evolution, provides important information for designing defence structures and for the development of a coastal management plan. The shoreline has a dynamic nature as it changes both in the short and long period. Those changes are caused by geo-morphological (e.g. bars and barrier island development etc.) and hydrodynamic (wave motion, tides and flows) processes, as well as by sudden and fast…

Municipal Integrated Coastal Management Facilitation in Latvia: Piloting Public Multi-Thematical Monitoring

2021

This paper contains a pilot study on coastal values and potential means of determining and characterising them in the terms of coastal planning and management. The research case study took place in the coastal region of North East Latvia – in the municipality of Salacgriva. The municipality coast is very diverse: coastal access, landscape and the whole biogeography is changing very much along the whole 54 km, being also rich in various natural and cultural heritage assets. Such great coastal variety in the limits of one administrative territory does require very selective governance approaches and dynamic management to be realized by local administration, which has very limited necessary ca…

Municipal Thematical and Territorial Indicator Systems for Sustainable Socio-Ecological Coastal Governance

2017

Abstract . There are recognized in Latvia the lack of locally based coastal socio-ecological research knowledge and its interpretation into municipal safety and development planning from one side as well as also only land-side oriented and separate sectorial development interests based coastal municipalities’ governance/planning practice from other side. Coastal governance practice development problems solution at the local level are to be seen at both ends of governance cycle – coastal situation evaluation (e.g. science) and policy design and implementation . Overall objective is to create, apply/test and use applicable interface system for integrated coastal science transfer into integrat…

Environmental effects of tourism and its seasonality on Mediterranean islands: the contribution of the Interreg MED BLUEISLANDS project to build up a…

2020

AbstractThe Mediterranean basin is amongst the world’s main tourist destination, and its islands are a major attraction, being sites of historical, cultural and naturalistic importance. This is beneficial for the local economies, but it may also represent a great burden on the coastal environment, where other human pressures are concentrated. The awareness of detrimental side effects of tourism together with the importance to take into account social and economic facets has led to the concept of sustainable tourism, which, however, represents a goal far from being attained. A good opportunity to promote sustainable tourism was provided by the Interreg MED BLUEISLANDS project, whose main aim…

Marine Litter Monitoring for Coastal Management Indicator System Development: Citizen Science and Collaboration Communication Approach

WebGIS Implementation for Dynamic Mapping and Visualization of Coastal Geospatial Data: A Case Study of BESS Project

2021

Within an E.U.-funded project, BESS (Pocket Beach Management and Remote Surveillance System), the notion of a geographic information system is an indispensable tool for managing the dynamics of georeferenced data and information for any form of territorial planning. This notion was further explored with the creation of a WebGIS portal that will allow local and regional stakeholders/authorities obtain an easy remote access tool to monitor the status of pocket beaches (PB) in the Maltese Archipelago and Sicily. In this paper, we provide a methodological approach for the implementation of a WebGIS necessary for very detailed dynamic mapping and visualization of geospatial coastal data

Development of Beach Litter Monitoring on the Latvian Coastline: the Citizen Science Perspective

2021

The research analyses the beach litter monitoring programme in Latvia and provides suggestions for its improvement seeking to provide necessary information for effective marine litter management on the Latvian coastline of the Baltic Sea. The beach litter monitoring programme has been enacted since 2012 by NGO “FEE Latvia” and current research has been focused on the situation assessment and particularly provides analyses on a number and distribution of the surveyed beaches, the frequency and timing of the monitoring, litter classification and counting methodology, as well as the possible programme development using the NGO work based on the citizen science approach. The results allow to el…

Late Holocene erosion of the Canopic promontory (Nile Delta, Egypt)

2017

International audience; The mouths of the Nile Delta are sensitive coastal areas, their geomorphology primarily being mediated by relative sea-level rise and sediment supply. To further document the Holocene evolution of the Nile's Canopic mouth, a core was taken from the southern shores of Abu Qir Bay, close to the ancient Canopic channel. Core bio-sedimentology and chronostratigraphy highlight four stages of marine incursion which are juxtaposed upon the general progradation trend of the Nile coast in this area. Compiled age-depth points from sediment cores taken in Abu Qir Bay underscore two phases of negative sediment budget at the Canopic mouth: (1) a first period, between 3.5 and 2 ka…

Shoreline Extraction and Change Detection using 1:5000 Scale Orthophoto Maps: A Case Study of Latvia-Riga

2015

Coastal management requires rapid, up-to-date, and
 correct information. Thus, the determination of coastal movements and its
 directions has primary importance for coastal managers. For monitoring the
 change of shorelines, remote sensing data, very high resolution aerial images
 and orthophoto maps are utilized for detections of change on shorelines. It is
 possible to monitor coastal changes by extracting the coastline from orthophoto
 maps. Along the Baltic Sea and Riga Gulf, Latvian coastline length is 496 km.
 It is rich of coastal resources and natural biodiversity.  Around 120 km of coastline are affected by
 significant coastal chang…
