Abstract

Purpose

Given the prevalence of protecting geoheritage tourism sites, Ladakh has enormous potential. However, Ladakh’s potential and developments in its growth as a geotourism destination have received scant consideration. As such, this paper aims to explore Ladakh’s key drivers as a potential geotourism destination through cognitive dissonance and protection motivation theories.

Design/methodology/approach

This paper conducted in-depth interviews with 86 geoscientists and tourism professionals to assess Ladakh’s potential as a geotourism destination. This paper used a qualitative approach to congregate four constructs based on the image difference of the consensus map.

Findings

Because of the interviewees’ heterogeneity and uniqueness, meaningful constructs in the consensus were included for each figure and cloud words. This paper concluded that four drivers are the main forces behind geotourism development.

Originality/value

This paper explores the drivers – geotourism services, legislative requirements, experiential geotourism and SPARC (scientific, preservation, aesthetic, recreational, cultural) values – affecting geotourism in Ladakh. It is feasible to lessen the negative effects of overtourism and make sure that Ladakh’s distinctive nature is preserved for future generations by implementing sustainable tourism practices.

Abstract

Purpose

Place-based, social studies teaching and learning has the potential to foster engaged citizens connected and committed to improving their communities. This study explored the research question, “In what ways do classroom and field-based experiences prepare teacher candidates (TCs) to make connections between place-based education and elementary social studies education?”

Design/methodology/approach

This qualitative case study examined how elementary TCs learned about, researched, curated and created place-based social studies educational resources related to community sites. Data collection included TCs’ Pre- and Post-Course Reflections as well as Self-Evaluations, which were analyzed using an inductive approach and multiple rounds of concept coding. Several themes emerged through data analysis.

Findings

The authors organized their findings around three themes: connections (i.e. place becomes personal), immersion (i.e. learning about place to learning in place) and bridge building (i.e. local as classroom). The classroom and field-based experiences in the elementary social studies methods course informed the ways in which TCs learned about and connected to the concept of place, experienced place in a specific place (i.e. downtown Statesboro, Georgia), and reflected upon the myriad ways that they could utilize place in their future elementary social studies classrooms.

Originality/value

TCs (as well as in-service teachers and teacher educators) must become more informed, connected and committed to places within their local communities in order to consider them as resources for elementary social studies teaching and learning.

Abstract

Purpose

The purpose of this study is to analyze the horizontal expansion of Burayu Town between 1990 and 2020. The study typically acts as a baseline for integrated spatial planning in small- and medium-sized towns, which will help to plan sustainable utilization of land.

Design/methodology/approach

Landsat5-TM, Landsat7 ETM+, Landsat5 TM and Landsat8 OLI were used in the study, along with other auxiliary data. The LULC map classifications were generated using the Random Forest Package from the Comprehensive R Archive Network. Post-classification, spatial metrics, and per capita land consumption rate were used to understand the manner and rate of expansion of Burayu Town. Focus group discussions and key informant interviews were also used to validate land use classes through triangulation.

Findings

The study found that the built-up area was the most dynamic LULC category (85.1%) as it increased by over 4,000 ha between 1990 and 2020. Furthermore, population increase did not result in density increase as per capita land consumption increased from 0.024 to 0.040 during the same period.

Research limitations/implications

As a result of financial limitations, there were no high-resolution satellite images available, making it challenging to pinpoint the truth as it is on the ground. Including senior citizens in the study region allowed this study to overcome these restrictions and detect every type of land use and cover.

Practical implications

Data on urban growth are useful for planning land uses, estimating growth rates and advising the government on how best to use land. This can be achieved by monitoring and reviewing development plans using satellite imaging data and GIS tools.

Originality/value

The use of Random Forest for image classification and the employment of local knowledge to validate the accuracy of land cover classification is a novel approach to properly customize remote sensing applications.

Abstract

Purpose

The purpose of this study was to investigate the likely causes of failure of some sections of road pavements in Ajaokuta, Northcentral Nigeria. This was achieved through a geotechnical assessment of subgrade soils in affected areas.

Design/methodology/approach

The methods entailed field and laboratory methods and statistical analysis. Subgrade soil samples were retrieved from a depth of 1,000 mm beneath the failed portions using a hang auger. The soils were analyzed for natural moisture content (NMC), Atterberg limit (liquid limit, plastic limit and linear shrinkage), grain size distribution, compaction and California bearing ratio (CBR), respectively.

Findings

The results of the geotechnical tests ranged from NMC (12.5%–19.4%), sand (84%–98%), fines (2%–16%), LL (16.0%–32.2%), PL (17%–27.5%), LS (2.7%–6.4%), PI (2.5%–18.4%), maximum dry density (1756 kg/m2–1961 kg/m2), optimum moisture content (13.2%–20.2%), unsoaked CBR (15.5%–30.5%) and soaked CBR (8%–22%), respectively. Pearson’s correlation coefficient performed on the variables showed that some parameters exhibited a strong positive correlation with r2 > 0.5.

Research limitations/implications

Funding was the main limitation.

Originality/value

Comparing the results with Nigerian standards for road construction, and the AASHTO classification scheme, the subgrade soils are competent and possess excellent to good properties. The soils also exhibited very low plasticity, a high percentage of sand, high CBR and low NMC, which implies that it has the strength required for road pavement subgrades. The likely causes of the failures are, therefore, due to the use of poor construction materials, technical incompetence and poor compaction of sub-base materials, respectively.

Abstract

Embedded in built environment discourse, this chapter examines the traditional knowledge and resilience of the Ngadjuri Nation Peoples through an Elder’s narrative of reconciliation as well as resistance in their subsisting colonial settlement. Removed from ‘Country’ in the 1840s, Ngadjuri Aboriginal community endured colonial industries of open-cut copper mining and large-scale pastoralism as irreparable destruction to their cultural landscapes. European processes in the resources sectors reshaped natural topographies, deconstructing Ngadjuri Songlines and Ancestral Dreaming stories. Burra’s colonial stone buildings of settlement, painstakingly cut and composed from materials of the surrounding ecological terrain, prompted new narratives from Ngadjuri as a way of alleviating scars. Broadly speaking, this chapter aims to show how cultural heritage of two communities is provocatively and conceptually unpacked through the vernacular buildings’ cross-cultural foundations. That is, an under-reported narrative was unwittingly bestowed on the colonial-built forms with hidden meanings that deserve further investigation. This chapter offers a counternarrative to colonial histories revealing Ngadjuri’s methods for reconnecting to Country and culture after generations of disempowerment. It explores how within the materiality of colonial structures, the Ngadjuri entwined their remediated storylines – revealing a data curation that had avoided popular discourse in the galleries, libraries, archives, and museums [GLAM] sector representation. This example implies there are bodies of knowledge in built cultural heritage hidden elsewhere on our Aboriginal Nations and the challenges it presents GLAM in their Indigenisation processes.

Abstract

Purpose

The purpose of this paper is to ascertain if practising healthy lifestyles improves the technical efficiency of farms in Kwara state, Nigeria. In theory, all deviations from the optimum level of output are due to random effects and inefficiency of producers in which their health plays a key part and is dependent on the kind of lifestyle practiced whether healthy or unhealthy.

Design/methodology/approach

Cross-sectional data were employed through a three-staged sampling technique to pick 320 arable crop farmers across the state using a well-defined questionnaire. Data analysis was carried out using descriptive statistics, healthy lifestyles index (HLI), stochastic production frontier (SPF) and propensity score matching (PSM).

Findings

First, the analysis showed that about one-third of the sampled arable crop farmers practised healthy lifestyles. Second, the average technical efficiency of arable crop production for farmers who practised a healthy lifestyle was 0.893, and the level of technical inefficiency of the farms was determined by health-related lifestyle status, number of day's illness and educational level. Third, technical efficiency was improved by 0.00431067 for farms whose farmers practised a healthy lifestyle.

Originality/value

Rather than seeing that technical efficiencies of farms are attributed to farm characteristics, inputs used and socioeconomic characteristics alone, the findings suggest that technical inefficiencies of arable crop farmers were also due to the kind of lifestyle practised, which was evidenced in the increased efficiency for farmers who practised healthy lifestyle.

Abstract

Purpose

The purpose of this paper is to investigate the impact of near-wall treatment approaches, which are crucial parameters in predicting the flow characteristics of open channels, and the influence of different vegetation covers in different layers.

Design/methodology/approach

Ansys Fluent, a computational fluid dynamics software, was used to calculate the flow and turbulence characteristics using a three-dimensional, turbulent (k-e realizable), incompressible and steady-flow assumption, along with various near-wall treatment approaches (standard, scalable, non-equilibrium and enhanced) in the vegetated channel. The numerical study was validated concerning an experimental study conducted in the existing literature.

Findings

The numerical model successfully predicted experimental results with relative error rates below 10%. It was determined that nonequilibrium wall functions exhibited the highest predictive success in experiment Run 1, standard wall functions in experiment Run 2 and enhanced wall treatments in experiment Run 3. This study has found that plant growth significantly alters open channel flow. In the contact zones, the velocities and the eddy viscosity are low, while in the free zones they are high. On the other hand, the turbulence kinetic energy and turbulence eddy dissipation are maximum at the solid–liquid interface, while they are minimum at free zones.

Originality/value

This is the first study, to the best of the author’s knowledge, concerning the performance of different near-wall treatment approaches on the prediction of vegetation-covered open channel flow characteristics. And this study provides valuable insights to improve the hydraulic performance of open-channel systems.
