Indicators of tourism development of the Serbian danube region

Protected natural area in the Danube region covers 107,200 hectares and includes two national parks, two nature parks, one place of outstanding natural beauty, five special natural reserves, twenty-five nature monuments, and two sites of international significance included in the Ramsar list. However, only 140 immovable and 374 movable cultural objects are officially registered. There are 31 cultural objects of exceptional importance and national significance and 89 objects of great importance and regional significance. The objects with this status are protected by the state. Two sites are on the preliminary UNESCO World Heritage list. This paper discusses the potential of tourism industry in the Serbian Danube Region and the prospects of its further development. We outline the current state of tourism industry and describe the geographical location of the region, its natural and anthropogenic resources, and accommodation capacities. We analyse such data as the number of tourists and the number of overnight stays by municipalities in 2016, and the average length of stay. The indicators used are the functionality coefficient, the capacity utilization and the intensity of functionality. The conclusion is drawn that the tourism potential of the Serbian Danube Region is not fully realized and that its development should be at a much higher level, given the increasingly important role of the region as a major tourist destination in Serbia

Agri-food markets towards sustainable patterns

In recent decades, the confluence of different global and domestic drivers has led to progressive and unpredictable changes in the functioning and structure of agri-food markets worldwide. Given the unsustainability of the current agri-food production, processing, distribution and consumption patterns, and the inadequate governance of the whole food system, the transition to sustainable agriculture and food systems has become crucial to effectively manage a global agri-food market able in supporting expected population growth and ensuring universal access to suffcient, safe, and nutritious food for all. Based on a critical review of the existing international literature, the paper seeks to understand the evolutionary paths of sustainability issues within agri-food markets by analyzing their drivers and trends. An extensive analysis was conducted highlighting the development and importance of the body of knowledge on the most important sustainability transition frameworks, focusing mainly on the relationship between markets, trade, food and nutrition security, and other emerging issues within agri-food markets. Finally, the study makes suggestions to extend the research in order to improve basic knowledge and to identify opportunities to design meaningful actions that can shape agri-food markets and foster their transition to sustainability

Far-travelled 3700 km lateral magma propagation just below the surface of Venus

Abstract The Great Dyke of Atla Regio (GDAR) is traced for ~3700 km on Venus, as a surface graben (narrow trough) interpreted to overlie a continuous laterally-emplaced underlying mafic dyke (vertical magma-filled crack). The GDAR belongs to a giant radiating dyke swarm associated with Ozza Mons (volcano), Atla Regio plume, and was fed from a magma reservoir ~600 km south of the Ozza Mons centre. A 50-degree counter-clockwise swing of the GDAR at 1200 km from the centre is consistent with a 1200 km radius for the underlying Ozza Mons plume head, and a stress link to the 10,000 km long Parga Chasmata rift system. Our discovery of the GDAR, should spur the search for additional long continuous single dykes on Venus (and Earth), with implications for estimating plume head size, locating buffered magma reservoirs, mapping regional stress variation at a geological instant, and revealing relative ages (through cross-cutting relationships) over regional-scale distances

Information and communication technologies for smart and sustainable agriculture

Agriculture faces different environmental, economic and social challenges that make the case for transition towards sustainability. Digitization is one of the most significant ongoing transformation processes in global agriculture. Information and Communication Technologies (ICTs) range from traditional communication aids (e.g. telephones, televisions), internet and mobile applications, to Big Data analytics and information systems, Cloud computing, Internet of Things, remote sensing and drones, blockchain and artificial intelligence. Different terms have been used to refer to the application of ICTs in agriculture e.g. digital agriculture, e-agriculture, smart agriculture, precision agriculture. This review paper analyses the potential of ICT in agricultural sector. In particular, it explores the benefits of ICT in terms of agriculture smartness and sustainability, provides an overview on the main technologies used, delineates the contours of the smart farming market and landscape, and analyses the potential drawbacks of such a ‘digital revolution’ in agriculture. Smart agriculture is presented by some scholars and practitioners as the ‘Third Green Revolution’, after the plant breeding and genetics revolutions. It is widely recognised that ICTs can help reducing inefficiencies, increasing resource productivity, decreasing management costs, and improving traceability and transparency. However, some caution is needed to make the ongoing ‘digital revolution’ in agriculture inclusive for small-scale farmers and women, especially in developing countries. Moreover, some threats and challenges relating to digital and smart technologies need to be appropriately addressed through policies to support the development of the necessary market and legal architecture for ICT and smart farming, with due consideration to ethical questions

Food wastage in Turkey: an exploratory survey on household food waste

International audienceIncrease in food demand, mainly due to population growth and diet changes, is putting an increasing pressure on food system and food security. In this framework, food losses and wastes (FLW) together create one of the main causes of food systems unsustainability. The two differ on the fact that food losses refer to the part of food that is lost along the supply chain before reaching final consumer while food waste represents the waste of food by final consumer. This paper focuses on the role of demographic, social and economic factors affecting household behavior related to food waste (FW) and explores some factors which can play an important role in tackling food waste issue in the case of Turkey. The paper is based on an online survey with150 Turkish respondents in January-March 2015. The sample was not gender balanced since71% of them were females. About two fifths of the respondents (38%) belong to the age group 35-44 years and 62% of the sample has a high level of education (master and PhD).The fact that the majority of the respondents are employees (70% of the sample) in the big cities of Turkey shows how the pace of the metropolitan life structure affects consumer food consumption habits and orient purchases towards supermarkets. The results of the survey show that still 95% of the respondents are responsible of FW and 90% think that food waste increases during the month of Ramadan. Nevertheless, about 50% of respondents declared the willingness to throw less away and ask for better information about the negative impacts of food waste on the environment and on the economy. Preventing bread waste campaign of the Ministry of Food, Agriculture and Livestock was launched in 2013 in order to increase consciousness of the society towards bread waste which is quite important in Turkey. Similarly, there are some other initiatives on both national and local level with the objective of informing people about the food waste, sustainable food consumption and reuse of the food through food recipes
