Climate change disaster is on the increase as the global temperature keeps rising. Sub-Saharan Africa is one of the most vulnerable regions to climate change. The coronavirus (COVID-19) pandemic has been complicated by climate change and related extreme events especially with the imposed lockdown which has affected the global economy. The COVID-19 has killed over 4 million persons with the USA, Brazil and India being the worst affected nations. Thus, the multi-hazard scenario presented by extreme events like drought, flood and cyclones this period of the pandemic worsened its spread as it affected social distancing and personal hygiene as many people are crammed in camps and water become scarce for handwashing. It is suggested for countries to strengthen their emergency department by boosting the staff component, provide adequate technical support and develop detailed plans for multi-hazard preparedness.","PeriodicalId":190157,"journal":{"name":"Central European Journal of Geography and Sustainable Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129245552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If, initially, they led to processes of crop homogenization, seasonal adjustment, homogenization of the landscape and markets standardization, they have subsequently pushed local communities towards a recovery of endemic biodiversity at risk of extinction because of such planetary processes, as well as a fundamental element in terms of local development, food security and sovereignty and reduction of environmental impacts. Starting from these instances of recovery and protection, which are increasingly taking place in Apulia, this work will examine both projects created \"from above\" and initiatives \"from below\", being the latter the result of a new consciousness that renews social cohesion and gives new value to the territorial milieu. In this regard, the case of the Salento km0 network will be examined: born in 2011 and now made up of 61 local subjects including producers, restaurateurs, associations, ethical purchasing groups and traditional stores, which represent a key symbol of a territory that resists and a population that has chosen to stay and innovate according to economic, social, cultural and environmental sustainability.","PeriodicalId":190157,"journal":{"name":"Central European Journal of Geography and Sustainable Development","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116930612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to examine domestic tourists’ motivation on revisit intention mediated by perceived benefits and perceived values. The quantitative data was collected through self-administered questionnaires from domestic tourists who travelled in Mongolia in the summer of 2019. An effect of domestic tourists’ travel motivation on revisit intentions; and the mediating effect of perceived benefit and perceived value were analyzed through factor analysis, regression analysis to test the proposed research hypotheses. The research result indicates that the mean ranking of the constructs of travel motivations for Mongolian domestic tourists were escape from daily life, relaxation, sightseeing, affordability of services, seeking variety, and culture were the top reasons to travel to the local destinations. The research findings contribute to the notion of domestic tourists’ travel motivation, its relationship between perceived benefit, perceived value of their trip on their willingness to return and recommendations to others. Furthermore, the research result could be beneficial for destination planners and tourism practitioners to enhance destination attributes and launch a variety of products, services, affordable pricing and accessible environment. Overall, the result provides background for an appropriate and effective marketing strategy to develop domestic tourism in Mongolia; and increase the competitiveness of the destinations with higher length of stay and more tourist spending.","PeriodicalId":190157,"journal":{"name":"Central European Journal of Geography and Sustainable Development","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127587410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Object Based Image Segmentation Algorithm of SAGA GIS for Detecting Urban Spaces in Yaoundé, Cameroon","authors":"Polina Lemenkova","doi":"10.47246/cejgsd.2020.2.2.4","DOIUrl":"https://doi.org/10.47246/cejgsd.2020.2.2.4","url":null,"abstract":"Present study is focused on the satellite image processing by means of SAGA GIS. The objective of the study is assessment and analysis of the core urban areas and its spatial distribution in the limits of the city and suburbs. The study area includes Yaoundé and its surroundings, Republic of Cameroon. The methodology includes Object Based Image Segmentation (OBIS) approach by SAGA GIS. The paper presents a methodologically structured workflow used in SAGA GIS for segmentation of the Sentinel-2A image. The segmentation techniques includes adjusting technical parameters, performing neighborhood approach and post-processing procedures (unsupervised classification, number of clusters). The OBIS model and SAGA GIS were used as main methods and machine learning techniques for image segmentation. Data include Sentinel-2A satellite image with high resolution (10 m). The image was analyzed by two approaches of cell neighborhood analysis: Moore and Neumann. The results showed following numerical parameters of the computed area: the perimeter of 1,060,560 km and an area estimated for the Yaoundé city 191,745,000 km2. The Neumann approach demonstrated better results for image clustering. The results presented automatically detected and separated segments of the city areas and other land cover types (savannah, forests, mountains). The spectral reflectance of various land cover types on a satellite image enables to group pixels of the image into classes using segmentation technique which has an important impact on the conceptual methodology of the urban mapping. The results of the image segmentation show the average values of the Neumann approach more correct in urban area than Moore approach. The accuracy assessment demonstrated 74.63% for the core urban area by using the Neumann method. The applicability of SAGA GIS for automated methods of image processing using machine learning algorithm of OBIS is presented and the advantages are discussed. The study demonstrated the effectiveness of the high-resolution Sentinel-2A for socio-economic studies, exemplified by urban mapping where remote sensing data serve as reliable sources of geoinformation. The advantages of the OBIS are discussed with detailed explanation of the SAGA GIS workflow.","PeriodicalId":190157,"journal":{"name":"Central European Journal of Geography and Sustainable Development","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132353875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
