  • Living on an ever-changing coast: French Guiana populations facing coastal
           mobility

    • Free pre-print version: Loading...

      Abstract: Abstract This article examines how the populations of French Guiana have, since the colonization period until today, inhabited the coast, in particular the cheniers close to the coast, whereas these spaces are subject to intense changes—colonization and destruction of the mangrove ecosystem, erosion, modification of the estuaries—which have significant consequences for living conditions and access to natural resources. The interdisciplinary approach brought together historians, geographers, geomorphologists, ecologists and anthropologists. Three contrasted areas were studied: Awala-Yalimapo, a Kali'na Amerindian village located at the Maroni estuary, the savannas region, between Sinnamary and Iracoubo where the Creole peasantry flourished, and finally, the particular case of the city of Kourou, built from the 1960s by the sea to house the engineers and technicians of the Guiana Space Center. This paper aims to propose a reflection on mobility and adaptability of the traditional habitat of the Amerindian and Creole populations, based on the collective appropriation of the land, and what could be described as a light approach to development. On the contrary, Kourou was built with a relationship to the sea largely imported from metropolitan France at a time when private property became the norm in French Guiana. The city is now facing serious erosion problems. As we question how to inhabit the coastline at a time when global change is likely to bring rapid transformations, knowing this history can be a valuable source of reflection for future coastal management strategies.

  • Impact of city expansion on hydrological regime of Rispana Watershed,
           Dehradun, India

    • Free pre-print version: Loading...

      Abstract: Abstract Rispana River flows through the heart of Dehradun, the capital city of Uttarakhand State, India. Uttarakhand had separated from Uttar Pradesh State in the year 2000; since then, Dehradun City has witnessed numerous changes. Both urban sprawl and densification were noticed, with around a 32% increase in population. The city had faced recurrent high runoff and urban flood situations in these last 2 decades. Therefore, the study was conducted to detect the change in land use/land cover (LULC), especially urbanization, through remote sensing data; and later to determine the impacts of such changes on the Rispana watershed hydrology. The LULC maps for the year 2003 and the 2017 were generated through supervised classification technique using the Landsat Series satellite datasets. The LULC change analysis depicted that mainly the urban settlement class increased with significant area among other classes from the year 2003–2017. It was noticed that majorly agriculture and fallow land (8.18 km2, which is 13.52% of total watershed area) converted to urban, increasing the impervious area. Almost all the municipal wards, falling in the Rispana watershed, showed urbanization during the said period, with an increase of as high as 71%. The change in LULC or effect of urbanization on the hydrological response of the watershed was assessed using the most widely used Natural Resources Conservation Services Curve Number method. It was noticed that the area under moderated runoff potential (approx. 10.23 km2) steeply increased during the lean season, whereas, high runoff potential zones (5 km2) increased significantly under wet season. Therefore, it was concluded that an increase in impervious surface resulted in high runoff generation. Further, such LULC change along with climate might lead to high runoff within the watershed, which the present storm drainage network could not withstand. The situation generally led to urban floods and affected urban dwellers regularly. Therefore, it is critical to assess the hydrological impacts of LULC change for land use planning and water resource management. Furthermore, under the smart city project, the local government has various plans to improve present infrastructure; therefore, it becomes necessary to incorporate such observations in the policies.

  • Appraisal of coexistence and interdependence of forest and tribes in
           Jhargram District of West Bengal, India using SWOT–AHP analysis

    • Free pre-print version: Loading...

      Abstract: Abstract Since time immemorial, forests and tribes have shown a close symbiotic relationship. Tribal communities have designed their livelihood strategies in accordance with the quantity and quality of forest ecosystem services. The indigenous human communities settled in the tropical dry deciduous forest of Jhargram District of West Bengal also exhibit similar multidimensional interactions with the forest ecology. But with the introduction of the market economy since the Colonial time has resulted in deforestation, de-speciation, and degradation. This put forth a question of sustenance and conventional living styles of these groups of people. This is further expected to be altered under the present combination of forest species. The present endeavor strives to assess the patterns of coexistence and interdependency between the forest and the tribes in the tropical dry deciduous forest tract of Jhargram District, with the help of SWOT–AHP analysis. The internal Strength (S) and Weaknesses (W) as well as the external Threats (T) and Opportunities (O) of the prevailing interaction framework have been identified through in-depth field visits and direct discussion with the stakeholders. Further, an Analytical Hierarchy Process (AHP) has been employed to ascertain the strategies for improvement of the subtle linkages between forests and tribes. The forces effective upon forest-tribe coexistence and traditional ecological knowledge of the indigenous forest people have been proved to be beneficial for livelihood strategies in the selected area, while selective restrictions need to arrest the major weaknesses and threats for the sustainability of forest-people coexistence.

  • Geospatial analysis of short term shoreline change behavior between
           Subarnarekha and Rasulpur estuary, east coast of India using intelligent
           techniques (DSAS)

    • Free pre-print version: Loading...

      Abstract: Abstract A geospatial analysis of shoreline change pattern is most significant parameter to understand the behavioral interaction between land and sea water. Geospatial analyses using various statistical and quantitative methods which are more applicable, accurate and dependable to measures the spatio-temporal trend of erosion accretion and estimate the change rate of shoreline. Remote sensing and GIS techniques have been used for the identification of shoreline change over the various time scales. To identify the rate Digital Shoreline Analysis System (DSAS) was applied in the current research. The present study aimed to identify the trend of coastal erosion accretion during 43 years (1975–2018) which is divided into four short term period (1975–1988, 1988–2000, 2000–2010 and 2010–2018) between the coastal stretch of Subarnarekha and Rasulpur estuary along Bay of Bengal using multi temporal satellite images. The accurate shoreline position has been delineated by the histogram threshold method using the images of Landsat Multi Spectral Scanner, Thematic Mapper and Enhanced Thematic Mapper. The shoreline change rate has been calculated based on cast transect method through some statistical techniques such as End Point Rate (EPR) and Net Shoreline Movement (NSM) in GIS application. 70.42 km long coastal stretch along Bay of Bengal has been divided into three littoral zones (LZ) to analyze the shoreline shifting on a zone basis. From the analysis it has been observed that maximum erosion occurred between 1988 and 2000 time period in all zones. The result shows that highest rate of net shoreline movement has been found in LZ I (− 1715.71 m) in 1975–1988 and LZ III (− 1719.65 m) in 2000–2010 at Subarnarekha estuary and Junput respectively. The present study reveals that most of the accretive formation is observed in 2000–2010 and 2010–2018. Major accretion is identified in the southern part of Subarnarekha estuary, 23.93 m/year in EPR method. Maximum shades of changes was experienced in LZ I, especially in Subarnarekha estuary area. In the time span of 1975–1988 this area faced the highest erosion and highest accretion with the rate of − 78.54 m/year and 23.93 m/year respectively through EPR method. During 1988–2000, − 37.35 m/year erosional rate was found in the Subarnarekha estuary. The highest erosional rate was − 8.48 m/year in Beguran Jalpai during 1988–2000 by EPR. The maximum rate of accretion has been noticed as 7.7 m/year in LZ II in the time period of 2010–2018.

  • Geographical structure of the local segregation of migrants in (sub)urban
           China

    • Free pre-print version: Loading...

      Abstract: Abstract Unprecedented urbanisation in China has profoundly reshaped the country’s social-spatial structure. Owing to economic suburbanisation and urban redevelopment processes, migrants coming from rural areas are increasingly concentrated in suburbs rather than city centres. Against this backdrop, this paper focuses on residential segregation between migrants and locals, and on geographical (re)structuring between the city centre and suburb. Theil’s H Index is used to disaggregate the migrant segregation of each municipality into a within-suburb, a within-centre and a between-centre-suburb component. We use Census data for 258 municipalities in 2000 and 2010; we find that migrant segregation increased in this period. We ascribe this to the increasing segregation of migrants in suburban areas, which offsets the increasingly balanced distribution of migrants between the city centre and suburb. Segregation in city centres also increased slightly in this period. Unexpectedly, less economically developed municipalities, defined by their per capita GDP, tend to be more segregated than their more developed counterparts. Less developed municipalities also have a higher level of suburban employment and housing opportunities in the whole municipality, but feature more segregated suburban spaces and a polarised distribution of migrants between the centre and suburb.

  • College location and labor market outcomes for STEM graduates in the US

    • Free pre-print version: Loading...

      Abstract: Abstract Broadening participation in STEM education, improving STEM graduate employability, and retaining a labor force with high STEM qualifications has become increasingly important in both higher education and regional development in the United States. However, few studies have examined the labor market experiences of STEM graduates. Drawing on interdisciplinary research, this study develops a framework that encompasses individual attributes, university institutional characteristics, and labor market factors to explore labor market outcomes for US STEM graduates. Based on analyses of multiple cohorts of STEM-educated college graduates in the US from 2000 to 2010, the study finds that there is a significant relationship between college location, STEM graduates’ job earnings, and the degree to which these graduates are underemployed or unemployed. We argue not only that college locations provide potential employment locations, but also that the interaction between students, universities and the regional context will last through students’ college years and factor into employment opportunities and levels of salary. Research and practice in higher education and regional development should be drawn on to coordinate efforts to increase graduate employability and promote collaboration between universities and industries.

  • BR-174 highway, geotourism and socio-environmental conflicts in the
           northern remote regions of the Amazon

    • Free pre-print version: Loading...

      Abstract: Abstract BR-174 in Brazil, also known as Manaus–Boa Vista, is a longitudinal highway that connects the Brazilian states of Mato Grosso, Rondônia, Amazonas and Roraima to Venezuela, being the only terrestrial connection between Roraima and the rest of Brazil. Its construction took place in 1968 and its inauguration in 1977, aiming to promote the interconnection of the State of Roraima, as a geopolitical strategy, with the rest of the country and, later, with South America. The construction of the BR-174 crossed the Waimiri Atroaris indigenous land, resulting in serious socio-environmental conflicts in the 1970s. Furthermore, recent research indicates that the deforestation process in the Amazon is associated with the opening of roads, as it favours the migratory flow, the occupation of land and logging. In this context, the arrival of migrants and, consequently, the pressing need to settle newly arrived people in search of land, favoured the damming of watercourses, the reduction of wild fauna and deforestation as a result of the construction of the road and neighbouring areas. However, and currently, BR-174 translates into a strategy of progress and communication, uniting adjacent communities, on the one hand, and, on the other, allowing the use of biophysical resources in favour of the development of geotourism. Considering this reality and from the perspective of the social and environmental transformations that have occurred, the objective of this paper is to analyse the potential of the BR-174 for the development of geotourism, as a way of mitigating its socio-environmental impacts and connecting geographically remote regions. The qualitative nature approach is based on the treatment and analysis of available bibliographic and documental sources. As the only land connection in the State of Roraima, and in addition to the negative impacts on the socio-environmental profile of the region, it can be concluded that the BR-174 highway has the potential to be an element facilitating the promotion of geotourism in the remote region of Amazon, contributing to the socio-environmental safeguard of this region.

  • Livelihood vulnerability assessment and climate change perception analysis
           in Arunachal Pradesh, India

    • Free pre-print version: Loading...

      Abstract: Abstract Climate change induced frequent disasters pose severe threats to agro-based rural livelihoods. Perceptions of risks play a critical role in planning and averting disasters. Lack of analytical documentation concerning how vulnerable communities perceive climate risks is a barrier to addressing and averting disasters and maladaptation. Applying a mixed approach, this study examines the perception of households concerning climate change and analyses the impacts of climate change on livelihood in Arunachal Pradesh, the largest northeastern state of India, with severe climate related challenges. Conceptual livelihood vulnerability index (LVI) framework of Intergovernmental Panel on Climate Change is adopted to analyse the climate change induced vulnerability on livelihood. A total 450 households from 18 villages located in the districts of Arunachal Pradesh were surveyed during October, 2021 for retrieving the ground complexities in the region. Decrease in yields, frequent landslides and floods, livestock losses and unpredictable weather condition were perceived by the sampled households. The LVI analysis indicated that households are vulnerable in Arzoo, Perum, Pekong and Amliang villages requiring priority for lessening livelihood vulnerability and increasing coping capacity of the communities. Correlation analysis indicated that climate variability, natural disaster, health, food and social components attributed to livelihood vulnerability in the study area. Alternate livelihood, enhancing preparedness to disasters, inclusion of women in workforce, sustainable livelihood practices and government assistance are some of the suggestions made to enhance the adaptation of local communities in a sustainable way.

           Manila, Philippines using landsat imagery

    • Free pre-print version: Loading...

      Abstract: Abstract Remote sensing technology has been widely used to address the issue of urbanization for monitoring. In Metropolitan Manila, Philippines, there is a decline in vegetation over the last decade. This leads to the excess heat in the surface temperature and a phenomenon known as Urban Heat Island. In this study, the land surface temperature (LST), land-use/land cover changes (LULC), normalized difference vegetation index (NDVI) and normalized difference built-up index (NDBI) in 2001 and 2019 were retrieved using Landsat 7 Enhanced Thematic Mapper + (ETM +). Our results showed the following: (i) an increase in the mean temperature of 4.02 °C from 2001 to 2019 in MM, (ii) rise in NDBI and a decline in NDVI values is correlated with an increase in LST over the last years in MM; (iii) LULC maps affirmed the highest occupancy of built-up areas caused by possible urban sprawl explaining the increase in warming in MM. This study provides added evidence that urbanization activities in Metro Manila leads to a warming effect that drives discomfort to many average Filipinos. Hence, environmental policies that would implement proper urban design utilizing more green spaces is recommended for local government units in MM to support.

  • The effect of khat cultivation on rural households’ income in Bahir Dar
           Zuria District, Northwest Ethiopia

    • Free pre-print version: Loading...

      Abstract: Abstract The study was conducted to evaluate the effect of khat cultivation on rural households’ income in the Bahir Dar Zuria district using cross-sectional data collected from 180 randomly selected respondents, and supported by focus group discussions in two districts of northwest Ethiopia. The data were analyzed by simple descriptive statistics and beta regression. Results from descriptive statistics show that khat contributes the largest (51%) of farmers’ income, followed by crop sale (33%), sale of livestock and their products (9%), and off-farm and non-farm activities (7%), Empirical findings from the Beta regression model also show that farming experience, education status, the proportion of land allocated for khat cultivation, total working capital of the household, the density of khat trees planted per hectare, and participation in off-farm and non-farm activity have a significant and positive effect on the proportion of khat income of the households. On the contrary, livestock holding, total asset ownership, and access to mobile phones have a significant and negative influence on the proportion of annual khat income of the households. Hence, the cultivation of khat can have a significant effect on the improvement of rural households’ income and standard of living in the districts. However, increased khat production have also serious implications on the market, water resources, and human health. Thus, policymakers need to come up together to understand and devise proper running mechanisms for these controversies of khat production in association with economic, social, and health implications.

  • The impact of drought on food security and sustainability in Jordan

    • Free pre-print version: Loading...

      Abstract: Abstract Jordan is a food-deficit country. Jordan’s population reached approximately 10 million in 2019 and has an annual growth rate of 3.3%. This increase will exert heavy pressure on the kingdom’s fragile natural resource base. The total imports of food commodities still exceed exports, so Jordan is a deficit country with respect to its food supply chain. Data from the Marfraq governorate were used to evaluate the effect of drought on food security in Jordan. This governorate was chosen because most of its land receives low levels of precipitation. The crops selected for analysis were rain-fed crops: olives, wheat, and barley. The precipitation data series were examined for normality distribution, and they were found to be normally distributed. Six drought severity classes were estimated by the Mafraq Governorate during 1995–2017. The highest drought occurrence was near normal drought (15 observation years), followed by moderate drought (3 years), extreme drought (2 years), and very wet and moderately wet (1 year each). The quantitative analysis for the effect of a drought occurrence on crop production was estimated using a regression equation with the assumption of increasing the average temperatures by 1 °C, 2 °C, and 3 °C. A conceptual model was designed to evaluate the impact of agricultural drought on some components of food security in Jordan. The standardized regression coefficients were estimated using the path analysis method. The total effect of drought on food availability was 0.68 standard deviations; the effect for food access was 7.01 standard deviations, and food utilization was 14.63 standard deviations. Climate change, especially drought occurrence, has a negative effect on food security. Crop yields are reduced with high temperatures. Additionally, weeds cover the land, and pest numbers increase, causing more damage. Crop production decreases substantially with low precipitation levels or long droughts. A drought’s indirect effects are evident through changes in irrigation water availability. The main purpose of this research is to understand the impact of drought on food security in Jordan by evaluating the drought effect on agricultural production and sociodemographic-economic aspects.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).

  • Dynamic of electoral behaviour in Uttar Pradesh: a study of lok sabha
           elections from 2009 to 2019

    • Free pre-print version: Loading...

      Abstract: Abstract Uttar Pradesh is one of the significant political spaces that offers a genuine academic analysis to Electoral Geography students. This political space interestingly presents the electoral dynamics rooted in many socio-cultural variants and has a more significant bearing on the electoral behavior of the masses in Uttar Pradesh. In this respect, the present paper organizes its conceptual design to correlate the electoral behavior of voters of Uttar Pradesh with the effects of the elements of culture and social structure. Primarily, this paper analyses the factors that control electoral behavior. It includes demographic politics, religion, cultural symbols, language, social stratification (Caste and sub-caste), rural–urban divide, and identity politics. These are the dominant factors in the social space of Uttar Pradesh that essentially controls the electoral behavior. The tendencies involved in the recent elections are observed in terms of electoral mobilization by political parties in Uttar Pradesh. The spatiality of populism, media campaign, caste alliance, religious sentiments, nationalistic issues, and leadership traits is the emerging trends utilized in the multiparty political democracy in Uttar Pradesh. Hence, the article is an ethnographic exploration of the relations between politics and social stratification, religion, and caste/community in Uttar Pradesh. This paper aims to examine the implications of cultural mobilization on these lines. Further, it observes how power has been transferred from parties that claim to favor social justice and subaltern politics like Samajwadi Party and Bahujan Samaj Party to Bhartiya Janta Party. This paper is generally based on secondary and archival sources; census data and electoral data are extracted from Newspaper reports, census, and the Election Commission of India. Primarily, It is a qualitative study where descriptive and analytical methods are applied. Arguments are framed through case studies and electoral data reports. The quantitative aspect of the analysis is represented through diagrams, graphs, and election statistics. The study shows that the evolution of the politics of Uttar Pradesh shows a visible sign of polarization mainly on the communal lines. Issues relating to the development of the region and its people are often sidelined in the face of communal division. Other factors like the ideology of the political party, local issues, caste, gender, and personality of the candidate intervene but with marginal effect.

  • Spatial multicriteria approach to water scarcity vulnerability and
           analysis of criteria weighting techniques: a case study in São Francisco
           River, Brazil

    • Free pre-print version: Loading...

      Abstract: Abstract The water availability deficit is a governance crisis and an environmental, social, and economic risk. This study presents a spatial multicriteria approach for mapping Water Scarcity Vulnerability (WSV) and a comparative analysis of criteria weighting techniques to support the management of water resources in semiarid regions. Initially, nine vulnerability indicators were identified from a literature review and spatialized through a Geographic Information System (GIS) for a water donor region and another recipient from the São Francisco River, in the semiarid region of Brazil. Subsequently, one subjective and two objectives weighting techniques were implemented and compared to measure the weights of the indicators. Finally, the Viekriterijumsko Kompromisno Rangiranje (VIKOR) method was combined with GIS to construct WSV maps. The results indicate the conditions of WSV in the transposition water donor region can be more critical than the region receiver, and the choice of the weighting method influences the results of the multicriteria-GIS approaches. The WSV mapping approach can be helpful for water management decision-making to identify priority areas and spatial inequalities. The comparative analysis in this study can provide a valuable reference for choosing weighting methods in spatial multicriteria applications.

      Abstract: Abstract The earliest case of Covid-19 was documented in Wuhan city of China and since then the virus has been spreading throughout the globe. The aim of this study is to evaluate the clusters of Covid-19 among the provinces in Turkey and to examine whether the clustering pattern has changed after the country’s lockdown strategy. The spatial dependence of Covid-19 in 81 provinces of Turkey was examined by spatial analysis between February 8 and June 28, 2021. Global and Local Moran's I and Gi* were employed to measure the global and local spatial autocorrelation degrees. The geographical distribution of Covid-19 in the provinces of Turkey showed a strong spatial autocorrelation while the spatial structure of the clusters varied by weeks. The findings of the study show that the complete lockdown carried out in Turkey has been quite effective in mitigating Covid-19. The importance of spatial relations in preventing the spread of the disease in Turkey has also been demonstrated in this context.

  • Assessment and monitoring of urbanisation on Himalayan lacustrine
           environment-a case study in Mirik municipality area

    • Free pre-print version: Loading...

      Abstract: Abstract The Mirik lake is a well-known tourist destination in the Darjeeling Himalayan region of West Bengal. In the last few decades, the lake area experienced a surge in demand for the hospitality industry with the consequences of unrestricted municipal town growth. On this perspective, this research work addresses the contemporary problems of the Mirk municipality area involving the lake system using technologies of remote sensing and GIS. In accordance with the primary objective, the detailed land use/land cover change analysis of the past twenty years shows a significant escalating trend in built-up area as it has increased from 149.85 ha in 2000 to 178.25 ha in 2020, where the lake expresses a steady reduction of its perennial part. The gradual shrinkage in the lake area may become of grave concern and therefore, this particular work tries to examine the water quality parameters of Mirik lake. Analyses have shown that the lake shrinkage may be attributed to waste disposal, landfill pollution etc., substantially contributed to the raised level of suspended sediment concentration (3724.26 mg/lit in 2020) near the boundaries. Moreover, the outcome of the developed water pollution model identifies that the western and south-western parts of the lake are the most polluted regions and confirms numerous inlets of the western side push up the level of phosphorus, nitrogen and biological oxygen demand in lake water. Such lake degradation is a real threat to the mountainous lacustrine environment, and it requires comprehensive plans for better management practices at some regular interregnum.

  • Crime in India: a spatio-temporal analysis

    • Free pre-print version: Loading...

      Abstract: Abstract Using National Crime Records Bureau and National Sample Survey data, this article explores the Spatio-temporal patterns of different types of crime in India. To explain these spatial patterns, we use spatial panel data regression techniques that account for spatial dependencies between different crimes and their socio-economic predictors at the NSS-region level. The results show that different types of crime have different time consistent spatial clustering of high and low crime regions. Evidence has been found that the prevalence of crime in a region is influenced by the crime rate of its neighbouring regions. This influence is linked to the spatial diffusion of criminal behaviour and harmful social norms that spread across contiguous regions over time. Our results also confirm the importance of various socio-economic variables like female literacy rate, sex ratio, inequality, regional prosperity, etc., in shaping the prevalence of crime in India. These findings could have significant implications for the policies aiming to reduce crime.

  • Patterns and driving factors of built-up land expansion in small
           provincial city in the Belt and Road Initiative: case study of Nong Khai
           City, Thailand

    • Free pre-print version: Loading...

      Abstract: Abstract China’s Belt and Road Initiative is the twenty-first century megaproject that will boost urbanisation and elicit expansion of new built-up land. However, little understanding exists concerning the expansion of new built-up land in small cities that will encounter urbanisation unavoidably. Thus, this study aims to clarify the patterns and driving forces behind built-up land expansion during the 1997–2017 period using Nong Khai City, Thailand–which has become an international hub in the Pan-Asia Railway Network–as a case study. Land-use maps were generated based on Landsat Satellite images and used to examine built-up land expansion, and driving forces were clarified through logistic regression using 16 independent variables based on four groups of driving factors. The findings indicate that built-up land expansion was the predominant pattern of land-use changes, with agricultural land transformed the most. Most independent variables affected the expansion with the same relationship, but magnitude varied during different periods. Socioeconomic and neighbourhood and spatial interaction factors were the most powerful driving forces during the 1997–2007 and 2007–2017 periods, respectively.
