[CEST2019_00223] Sustainable landscapes: restoration and land use planning in an adaptive approach to climate change and desertification. Case study of Inter-Andean Valley of Cauca River in Colombia.
by Alvarado-Solano D.P., Otero J.T., Šarapatka B.

The inter-Andean valley of Cauca River (IVCR) is one of the most industrialized regions in Colombia leading its seasonally dry tropical forest (SDTF) to a fragmented and degraded state. Changes in land cover may alter the climatic and hydrological patterns. In the period 1984 – 2014, 26% of natural areas detected remotely at IVCR have persisted in a sugarcane matrix. However, IVCR species composition and its ecological status are unknown. After reviewing several datasets, 1725 plant species were compiled. Using a modelling approach, habitat suitability was predicted with a maximum entropy algorithm implemented in Biomod2 R-Package for 14 prioritized plant species. Models were produced using as predictors, the variables selected with their Variance Inflation Factor (VIF) and for those selected with a Principal Component Analysis (PCA). Although the selected variables differed between VIF and PCA, the geographic space predicted to be suitable for the species were similar. VIF and PCA variables strongly reflect the temperature and precipitation under warm and wet periods and their seasonality. These models will help to estimate the potential restoration of SDTF at the ICVR and its vulnerability to climate change. This information will contribute to planning effectively the IVCR landscape for the future.

[CEST2019_00229] Waste Management System and Its Effects on the Water Quality of an Ecotourism Destination in Caramoan, Camarines Sur, Philippines
by Moico C., Florece L., Ancog R., Cereno R.

Caramoan is a municipality located in the far eastern end of Camarines Sur in the region of Bicol, Philippines. The islands of Caramoan has been the site of several editions of the international reality TV show Survivor since 2008. After being featured in the show, its popularity spread like wildfire and the volume of tourist visitors escalated. The tourism industry boosted the municipality’s economy and brought income generating opportunities to its communities. Changes in the physical, environmental and social dynamics became noticeable over the years. Resorts were intensively built in shorelines, farmers shifted to tourism-related business and services and problems on waste management emerged. The worsening problem on wastes became the most challenging in one community of the municipality. This study was conducted to assess the waste management of the community and how it affects the coastal water quality. Results showed that the community and tourists gave high importance on proper waste management but the local government unit showed weak policy implementation. As an additional validation, coastal water quality tests on DO, BOD, pH, TC and TFC were done for two distinct seasons. Results showed that water is still within the standards of the Environmental Management Bureau (EMB) – DENR, Philippines.

[CEST2019_00244] Risk analysis for gas pipelines: A sustainability assessment approach using bow-tie analysis
by Panagopoulos J., Karayannis A., Karayannis P. ,Gouvalias G.

Vast amounts of natural gas (NG) are consumed around the world everyday that are mainly transported and distributed through pipelines. Integrity of these pipelines is of primary interest to NG companies, consultants, governmental agencies, consumers and other stakeholder due to adverse consequences and heavy financial losses in case of system failure. Fault tree analysis (FTA) and event tree analysis (ETA) are two graphical techniques used to perform risk analysis, where FTA represents causes (likelihood) and ETA represents consequences of a failure event. 'Bow-tie' is an approach that integrates a fault tree (on the left side) and an event tree (on the right side) to represent causes, threat (hazards) and consequences in a common platform. The present study aims to help owners of transmission and distribution pipeline companies in risk management and decision-making to consider multi-dimensional consequences that may arise from natural gas pipeline failures.

[CEST2019_00099] Fortified settlements between the Ambracian Gulf and Acherontas River in Preveza
by Saltagianni E., Katsaounou S., Gousis Ch.

The prefecture of Preveza is an area that has been an ideal place to live because there are the fields (are necessary for cultivation), the mountains (important for safe landscape), the rivers (are necessary for drinking water and watering the fields) and the sea (for trade and fishing). Such a landscape is formed between Acheron river and Louros river and their tributaries. Ιn this article we will talk about two fortified settlements near Louros river and its tributary: the castle of Rizobouni and the Kastle of Rogon. These castles are fortified settlements of antiquity and grew again in the Byzantine era and the Ottoman period. The natural environment was an important factor for the selection of these places and their continuous habitation up to the Ottoman conquest. The aim of the article is to present the ancient remains in combination with the natural landscape, to protect the antiquities and the environment, to promote tourism development without altering the environment, looking for environmental management and policies and the environmental impacts of tourism without proper organization

[CEST2019_00100] Fortified settlements during the Ottoman conquest in Thesprotia
by Saltagianni E.

The area of the prefecture of Thesprotia was conquered by the Ottomans before Constantinople and the final decline of Byzantium. There are fortified sites built after the Ottoman conquest in accordance with the new techniques and requirements of the era. There are also fortified places that were walled in antiquity and continued to be inhabited throughout the Ottoman period. The choice of location had, among other reasons, natural causes such as physical protection, proximity to a river and the relationship of the settlement with the surrounding area. The aim of the work is to present the Ottoman fortifications of Thesprotia (for example: the castle of Margariti, the castle of Igoumenitsa, the castle of Paramythia and the fortificated site of O(ouz)sdina in Thesprotia and their relation to the natural environment as well as the possibility of a good tourist promotion

[CEST2019_00119] Deciphering Coastal Vulnerability Index (CVI) for the coastal areas of Rhodes Island and the possible impact on tourism
by Vandarakis D., Kyriakou K., Loukaidi V., Kyriakidou Ch., Gad F-K., Sourianos E., Kapsimalis V., Drakopoulou P., Kikaki A., Hatiris G-A, Panagiotopoulos I.P., Chatzinaki M., Morfis I., Sioulas A., Kanellopoulos Th., Livanos I.

Rhodes Island, located in the southeastern Aegean Archipelagos. Coastal areas, extended sandy beaches, people’s hospitality, and adequate infrastructure are principal factors that have increased the touristic value of the island. The estimation of the Coastal Vulnerability Index is important, since coastal environments play an important role for the tourist decision. Coastal systems are the most sensitive in environmental changes. In this study CVI is used, in order to indicate the most vulnerable areas, through the interpretation and the calculation of various parameters. The data for the calculation of the CVI were mainly geomorphological, as long as fieldwork and laboratory analysis. The data were interpreted through GIS platform. GIS environment contributes to the simultaneous processing of all these data, the representation of the spatial distribution of these parameters, and finally to depict of the most vulnerable areas. Thus, these results will contribute to the most suitable, sustainable solutions for the decision making authorities.

[CEST2019_00054] Offshore windfarm siting in Greece using GIS and TOPSIS
by Spyridonidou S., Vagiona D.

The deployment of offshore wind power technologies is becoming increasingly important towards the sustainable development of regions. In Greece, wind energy is provided at the time being, only by onshore plants and the interest in investigating the top choices for offshore wind applications in terms of environmental, economic, social and technical criteria is rapidly growing. The aim of this paper is to investigate the most appropriate sites for offshore windfarm siting in swallow waters (water depth ≤50m), where it is economically or/and technologically feasible to have structures resting directly on the seabed to support the turbine structure, taking advantage the existing knowledge as well as the technical experience of such applications. The proposed methodology includes two distinct stages (exclusion and evaluation) and integrates Geographical Information System (GIS) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method for solving spatial and policy planning problems. Thirteen exclusion criteria (e.g. wind velocity, distance from electricity grid, distance from residential network) and six assessment criteria (e.g. electricity energy production, distance from marine protected areas) are considered in the analysis. The results reveal five sites in swallow waters for offshore windfarm siting that could contribute to the energy interdependency of many areas.
