Over 5,000 voluntarily recorded tracks spread over 10 years have been analysed, showing a predominance of cycling activities on trails of up to 50 km in length. Using cluster analysis and a hotspot approach, we found that the highest intensities of use are concentrated in less than 1% of the area studied, while a high dispersion of track start/finish points suggests low but scattered pressure all over the site. Spatial analysis reveals a number of spatial interactions, including the use of official trails, trespassing on reserves and potential nuisance to birdlife. This information is useful for site managers and helps them design sustainable practices. By applying the same analysis using VGI and data mining to other Natura 2000 sites, comparisons can be made and thus provide valuable assessment regarding visitor monitoring and public use patterns for the largest network of protected areas in the world.","PeriodicalId":45790,"journal":{"name":"Geografisk Tidsskrift-Danish Journal of Geography","volume":"44 1","pages":"69 - 83"},"PeriodicalIF":2.3,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74363137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have shown that riparian lowlands (alluvial plains, wetlands, meadows), if present, may act as buffer zones with high nutrient retention capacities. To assess the fate of water and nutrient flow in riparian lowlands in tile drained catchments, it is essential to know the locations of tile drainage outlets as sources of nutrient input. Using a thermal infrared (TIR) remote-sensing survey, we identified potential tile drainage outlets in a riparian lowland. We also applied a normalized differentiated vegetation index (NDVI) approach to illustrate how tile drainage outlets can be identified with free broadband RGB-NIR data. The positions of identified outlets were validated in the field by visual observation. Our study finds that TIR remote sensing is a strong tool when assessing the sources of water input. NDVI is also applicable, however the background values are very variable making the outlets difficult to locate. The results can be applied in studies of water movement and solute transport via tile drainage as well as model studies where knowledge of input areas through tile drainage is of great importance.","PeriodicalId":45790,"journal":{"name":"Geografisk Tidsskrift-Danish Journal of Geography","volume":"34 1","pages":"105 - 94"},"PeriodicalIF":2.3,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77098317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geoengineering offers an immediate response to climate change which might instantly offset these “dangerous” impacts by deliberately altering the climate system to cool the planet. This arguably places geoengineering experts at the centre of future climate change and security policies. Based on empirical data from interviews with renowned geoengineering scientists, this article explores how these geoengineering specialists label and delimit their work when seeking to claim scientific expertise and autonomy from security politics, while arguing for the relevance of their research on climate change. The study shows an ambiguity between how the geoengineering specialists see the scientific potential of their research, and their unease towards the security applications of this very research. A clear distinction between “geoengineering” and “geopolitics” is drawn and upheld using different rhetorical styles, but dissolves when personal strategies and security politics emerge. On this background, the article discusses the imaginary boundary between (security) politics and (geoengineering) expertise, and suggests more transparent and reflexive science in society.","PeriodicalId":45790,"journal":{"name":"Geografisk Tidsskrift-Danish Journal of Geography","volume":"1 1","pages":"84 - 93"},"PeriodicalIF":2.3,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75304348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from the Land Parcel Identification System (LPIS) are potentially useful to assess agricultural land use dynamics as they contain detailed information on agricultural land use. In this paper, we therefore analyse data from two individual studies, one from Flanders and one from Denmark, to explore whether LPIS data are applicable to assess farmland loss. Our results show that in both Flanders and Denmark, around 4.5% of the total registered farmland area in LPIS was lost in a 5-year period (2008–2013 for Flanders and 2011–2016 for Denmark). Complementary land use data and aerial photo interpretation reveal that the majority of lost registered farmland still was in agricultural use after 5 years. Hence, the confirmed loss was only around 0.5% for Flanders and Denmark. We conclude that both Flemish and Danish LPIS data only with some difficulty are able to quantify loss of farmland and therefore question if LPIS data alone are suitable to assess change in farmland area. The major part of farmland leaving the register is most likely related to a general change in agricultural structure.","PeriodicalId":45790,"journal":{"name":"Geografisk Tidsskrift-Danish Journal of Geography","volume":"63 1","pages":"17 - 29"},"PeriodicalIF":2.3,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74414531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To increase the transparency of planning and its usefulness for public and private actors, planning authorities have integrated production and online distribution of digital plan data within existing planning practices and workflows. Many European countries have established public spatial planning databases. Denmark is one of the forerunners in that digitalization. Since 2006, all legal plans are registered in an open geodatabase including over 34,000 currently effective local development plans. Despite the obvious potential of such data to inform about planning practice and associated outcomes, research using these new data is rare, mainly focusing on technical or judicial aspects. Questions related to planning practice, efficiency, evaluation and design have hardly been looked into. In this paper, we provide a short overview of digital plan data in the Danish database as well as similar data in Nordic countries. We then discuss research perspectives regarding plan evaluation and planning practice and we argue that digital plans represent a new transdisciplinary type of intentionally explicit data source for analysis of land change processes.","PeriodicalId":45790,"journal":{"name":"Geografisk Tidsskrift-Danish Journal of Geography","volume":"1 1","pages":"16 - 6"},"PeriodicalIF":2.3,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77142116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Normalized difference built-up index (NDBI) was used to extract built-up areas and population density was retrieved from LandScan data, while elevation and slope were obtained from ASTER DEMs (30 m). Four types of canopy density were delineated with crown cover above 71%, 41–70%, 11–40%, below 10% and areas with no canopy cover, that is 0%. A sharp decline in forest area occurred during 1989–2016 at a rate of loss of 2.9 % year-1 with an average rate of deforestation of 3051 ha year-1. Dense forests exhibited remarkable degradation, especially towards the central valley. The variation in the topographical (elevation and slope) gradient resulted in significant differences in the canopy density over the study area barring some hill slopes. Population pressure and various developmental activities in recent decades led to forest degradation in this fragile yet rich Eastern Himalaya biodiversity hotspot.","PeriodicalId":45790,"journal":{"name":"Geografisk Tidsskrift-Danish Journal of Geography","volume":"43 1","pages":"137 - 150"},"PeriodicalIF":2.3,"publicationDate":"2018-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73890778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through spatial analysis and quantitative research this study explores sequencing of servicing and housing development as it impacts city spatial growth patterns in a context of resource deficiency in Dar es Salaam City. The study finds that despite households’ land ownership being crucial in city spatial expansion process towards residential house ownership, their actual construction and occupation will depend on the accessibility of services. Moreover, it was established that as more services become available, proportionally, number of people settling in new areas increases. Since this process happens equally in planned and unplanned settlements, this study indicates that it is the availability of services and not land allocation that triggers actual development of residential housing. Thus, service provision determines the pace of change in short and medium city spatial patterns. This implies that in the context of public resource deficiency and self-help housing, strategic investments in basic services such as electricity connection, public transport and portable water is the way to influence actual city development pattern rather than providing plots.","PeriodicalId":45790,"journal":{"name":"Geografisk Tidsskrift-Danish Journal of Geography","volume":"29 1","pages":"151 - 159"},"PeriodicalIF":2.3,"publicationDate":"2018-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91358003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A set of eight criteria were selected in order to analyse and determine the appeal that each cave may have for visitors. Establishing the “degree” of appeal as an indicator of the tourism and geographic absolute attractiveness value is based on a principal components factor analysis; the resultant single factor was correlated with our selected criteria. We find a strong correlation between touristic cave attractiveness and cave locations, ease of cave passage access (vehicle and trail) infrastructures, cave location in main tourism regions, and the growth of urban areas as they encroach on show cave locations. Similar studies in valorization of show caves tourism have not been attempted in Slovakia or Eastern Europe.
