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.

跨界合作和中国不同层级政府角色的变化——以广佛都市圈为例

As few studies have been conducted on the roles of governments at different levels in cross-boundary cooperation process,this paper,drawing on the multi-level governance theory,explores the roles of local governments in cross-boundary cooperation in China through in-depth interviews and document analysis in the Guangzhou-Foshan metropolitan area.The paper finds that China has seen a significant advance in cross-boundary cooperation in terms of institutional building and a remarkable change in municipal and provincial government functions.The new forms of regional cooperation have enhanced horizontal ties,but political directives from the central government cannot simply be ignored as existing administrative hierarchy is stll a pervasive principle.The power devolution is essentially the transfer of power from the central government to pro-vincial-and municipal-level governments(or prefecture city governments)but overlooks the district and county governments.Furthermore,citizens and non-government institutions have no access to the decision-making process and channels for airing their appeals.In a real sense,the regional cooperation systemhas not yet been well established.

基于控制单元划分的南海区广佛跨界水环境治理工程效果评估

针对南海区广佛跨界区域的水系分布特点划分控制单元,通过对2018年区域内治水工程的调研分析,定量分析治水工程效果。跨界区域各控制单元中,水口水道的COD和NH_3-N削减量最大,占比分别为42.9%和62.9%;西南涌的TP削减量最大,占比为60.1%;按行政区划分析大沥镇对COD和NH3-N的削减贡献最大,占比分别为29.8%和35.4%;狮山镇对TP的削减贡献最大,占比为62.9%。通过建立污染物削减量与水质指标的响应关系,对控制单元合理性进行分析,并提出相应的污染防治对策,可为管理部门制定水污染防治计划及环境整治工程提供技术支持。
