Renewable Energy Sources are expected to play a very important role in energy production in the following years. They constitute an energy production methodology which, if properly enabled, can ensure energy sufficiency as well as the protection of the environment. Energy production from biomass in particular is a very common method, which exploits a variety of resources (wood and wood waste, agricultural crops and their by-products after cultivation, animal wastes, Municipal Solid Waste (MSW) and food processing wastes) for the production of energy. This paper presents a Spatial Decision Support System, which enables managers to locate the most suitable areas for biomass power plant installation. For doing this, fuzzy logic and fuzzy membership functions are used for the creation of criteria layers and suitability maps. In this paper, we use a Multicriteria Decision Analysis methodology (Analytical Hierarchy Process) combined with fuzzy system elements for the determination of the weight coefficients of the participating criteria. Then, based on the combination of fuzzy logic and theAnalytic Hierarchy Process (AHP), a final proposal is created thatdivides the area into four categories regarding their suitability forsupporting a biomass energy production power plant. For the two optimal locations, the biomass is also calculated.The framework is applied to theRegional Unit of Drama, which is situated in Northern Greece and is very well known for the area’s forest and agricultural production.

E-tourism refers to the broader integration of Information and Communication Technologies (ICTs) in the tourism sector and infrastructure. In this context, tourists can choose the travel destination, use price comparison sites and buy online tickets at low prices, while tourism entrepreneurs enhance their marketing strategies in response to the increasing demands of modern tourism Over the last few decades, alternative tourism has gained considerable interest among tourists and enterprises in the tourism industry. At the same time, it acts as an enabler and a facilitator of sustainable development. This paper presents an overview of the current situation of content characteristics of the websites of enterprises involved with alternative tourism services in Greece. The websites are evaluated according to 30 characteristics through multicriteria method. Furthermore, the final ranking of websites is presented to identify the most successful strategies, as well as the website that need improvements. According to the results, an e-tourism website model is suggested for the entrepreneurs to exploit the opportunities that arise in the digitalization transformation of the tourism industry.

As a global actor, the European Union (EU) plays a leading role in international efforts to promote sustainable development globally. All sustainable objectives and targets need Information and Communication Technologies (ICTs) as key catalysts, since ICTs constitute tools of unprecedented power which help people to face the growing challenges of rising population, poverty, epidemics and climate change. Policy makers in the EU are increasingly putting ICTs into relations with sustainable regional development. This paper aims to study and assess the impact of ICT on the EU regional policy in terms of sustainable development by applying the multicriteria approach, PROMETHEE II, using the software Visual PROMETHEE. The criteria that were used in this research are the criteria that both the European Commission and member states define to assess the ICT implications of new EU legislation since 2010. The results revealed that the impact of ICT on EU sustainable regional policy has gotten stronger in the last two decades.

Development Agencies constitute an innovative institution aiming to support integrated local development in rural areas, hence contributing to the transformation of economy. Shareholders are public and private organisations such as local prefectures, municipalities, scientific societies, unions, cooperatives as well as natural bodies. As internet has facilitated new prospects and opportunities for all to benefit, various websites were also established representing local development agencies. This paper aims to identify and study website content characteristics and to classify them according to their content. Most retrieved websites are information-based websites yet they can further evolve in e-service delivery.
