Possibilities and Opportunities of Wine Tourism Development in the Cross-Border Region of Greece-Bulgaria Through the Protection of Traditional Vine Varieties

Wine tourism as an alternative form of tourism is developed in rural areas with significant wine production.But rural areas are usually not characterized by dynamic local economies.Therefore the contribution of wine tourism to regional development is important.In the region we will focus on the present paper,i.e.,the countries of Greece and Bulgaria,where the tradition in viticulture and production of quality wines is long.Especially in the cross-border area of Greece-Bulgaria,wine production is very remarkable.The project“VineSOS-SOS for endangered traditional vine varieties”implemented and funded by the Program“Cooperation Program Interreg V-A Greece-Bulgaria 2014-2020”identified local grape varieties in danger of extinction.In addition,a comprehensive intervention mechanism was formed for greater protection and sustainability of these varieties.The next step after the protection and promotion of these varieties is their utilization for the region with the development of a common wine tourism product for the cross-border area of Greece-Bulgaria.The present research seeks to utilize the results of the VineSOS project to develop a proposal for wine tourism development in the cross-border region of Greece-Bulgaria as a single tourist product.The main hypothesis of our research concerns the investigation and formulation of a strategy for the development of wine tourism in the cross-border region of Greece-Bulgaria based on the rare vine varieties found in the region.The development of this strategy emerges through the study of the international literature on wine tourism and the study of good practices at the international level,as well as through the special features of the cross-border area of Greece-Bulgaria.

Spatio-Temporal Dynamic of Land Use in the Dja-Odzala-MinkébéLandscape between Cameroon, Congo and Gabon: Influence on the Evolution of Forest Cover in a Context of Cross-Border Cooperation

This study is being carried out in the cross-border area of the tri-national Dja-Odzala-Minkébé (TRIDOM), subject of a cooperation agreement between Cameroon, Congo and Gabon in 2005. The purpose of this study is to analyze the dynamics of changes in land use in the context of cross-border cooperation. Geographic information systems and remote sensing were used to produce the various land use maps. For this purpose, the MERIS satellite images for the periods 1992, 2005 and 2018 were used. The exploration of the different images and the field visits made it possible to identify the following six land use classes: dense forests, degraded/deforested forests, savannas, swamp forests, buildings and bare soils, water surfaces. It emerges that the TRIDOM landscape is mainly occupied by dense forests which represent 97.02%, 96.72% and 96.52% respectively in 1992, 2005 and 2018. Then, degraded/deforested forests and savannas which would correspond to cultivation areas and fallow land only represent respectively 1.06% and 0.68% of the landscape in 1992. This proportion in 2005 is respectively 1.22% and 0.77%, whereas in 2018, it is respectively 1.36% and 0.81% of the massif. The landscape of TRIDOM has not experienced any significant land use change during the period after the signing of the cooperation agreement. Historical rates of deforestation are low during the period under study. They are estimated at 0.042% and 0.030% respectively for the period 1992-2005 and the period 2005-2018. These low rates of deforestation seem to be due to the measures taken to secure and sustainably manage the massif taken by the three countries, the low population density in this area and the still difficult level of accessibility of a large part of the massif.

黑龙江流域中俄跨境地区0.25°×0.25°有效积温数据集(2002–2020)

作者以黑龙江流域中俄跨境地区为研究区,以0、5、10和15℃为基础温度,基于大气再分析数据产品ECMWF Re-Analysis 5中的逐小时2 m气温数据,通过时空筛选与尺度转换、有效温度始末日期甄别,以及区间数据批量统计等步骤,得到黑龙江流域中俄跨境地区0.25°×0.25°有效积温数据集(2002–2020)。将本数据产品(有效积温)与基于气象实测数据及其关联产品的有效积温进行相关性分析表明,本产品与两者均呈正相关关系,并且年际间波动情况基本一致。本数据集内容包括:(1)研究区边界数据;(2)研究区2002–2020逐年0.25°×0.25°有效温度(≥0、≥5、≥10和≥15℃)始末时间数据;(3)研究区2002–2020逐年0.25°×0.25°有效积温(≥0、≥5、≥10和≥15℃)数据;(4)有效积温的验证数据。数据集存储为.shp、.tif和.xlsx格式,由305个文件组成,数据量为19.9 MB(压缩为1个文件,1.69 MB)。
