The purpose of this paper is to apply the concept of “Interconnected Geoscience” to a disaster and risk reduction (DRR) case study at SECMOL College, near Leh, Ladakh, N. India. Interconnected geoscience is a model that advocates holistic approaches to geoscience for development. This paper reports research/practical work with Ladakhi students/staff, undertaking community-oriented DRR exercises in hazard awareness, DRR themed village/college mapping, vulnerability assessments and DRR management scenario development. The geoscientific hazard analysis work is published within a separate sister paper, with results feeding into this work. This work addresses aspects of, and contributes to, the DRR research(science)-policy-interface conversation.

Interconnected geoscience methodologies for DRR here are: the application of geoscience for hazard causality, spatial distribution, frequency and impact assessment, for earthquakes, floods and landslides, within the SECMOL area; the generation of community-developed DRR products and services of use to a range of end-users; the development of a contextual geoscience approach, informed by social-developmental-issues; and the active participation of SECMOL students/teachers and consequent integration of local world-views and wisdom within DRR research. Initial DRR awareness levels of students were assessed with respect to earthquakes/floods/landslides/droughts. Following hazard teaching sessions, students engaged in a range of DRR exercises, and produced DRR themed maps, data, tables and documented conversations of relevance to DRR management.

Students levels of hazard awareness were variable, generally low for low-frequency hazards (e.g. earthquakes) and higher for hazards such as floods/landslides which either are within recent memory, or have higher frequencies. The 2010 Ladakhi flood disaster has elevated aspects of flood-hazard knowledge. Landslides and drought hazards were moderately well understood. Spatial awareness was identified as a strength. The application of an interconnected geoscience approach immersed within a student+staff college community, proved to be effective, and can rapidly assess/build upon awareness levels and develop analytical tools for the further understanding of DRR management. This approach can assist Ladakhi regional DRR management in increasing the use of regional capability/resources, and reducing the need for external inputs.

A series of recommendations for the DRR geoscience/research-policy-practice area include: adopting an “interconnected geoscience” approach to DRR research, involving scientific inputs to DRR; using and developing local capability and resources for Ladakhi DRR policy and practice; using/further-developing DRR exercises presented in this paper, to integrate science with communities, and further-empower communities; taking account of the findings that hazard awareness is variable, and weak, for potentially catastrophic hazards, such as earthquakes, when designing policy and practice for raising DRR community awareness; ensuring that local values/world views/wisdom inform all DRR research, and encouraging external “experts” to carefully consider these aspects within Ladakh-based DRR work; and further-developing DRR networks across Ladakh that include pockets of expertise such as SECMOL.

The term “interconnected geoscience” is highly novel, further developing thinking within the research/science-policy-practice interface. This is the first time an exercise such as this has been undertaken in the Ladakh Himalaya.

Societies depend on interconnected infrastructures that are becoming more complex over the years. Multi-disciplinary knowledge and skills are essential to develop modern infrastructures, requiring close collaboration of various infrastructure owners. To effectively manage and improve inter-organizational collaboration (IOC) in infrastructure construction projects, collaboration status should be assessed continually. This study identifies the assessment criteria, forming the foundation of a tool for assessing the status of IOC in interconnected infrastructure projects.

A systematic literature study and in-depth semi-structured interviews with practitioners in interconnected infrastructure construction projects in the Netherlands are performed to identify the criteria for assessing the status of IOC in infrastructure construction projects, based on which an assessment tool is developed.

The identified assessment criteria through the literature and the practitioner’s perspectives results in the designing and development of a collaboration assessment tool. The assessment tool consists of 12 criteria and 36 sub-criteria from three different categories of collaborative capacity: individual, relational, and organizational.

The assessment tool enables practitioners to monitor the status of IOC between infrastructure owners and assists them in making informed decisions to enhance collaboration. The assessment tool provides the opportunity to assess and analyze the status of collaboration based on three categories (i.e., individual, relational, and organizational).

This paper places a college at the centreof a multi-hazard assessment (earthquake, flood and landslide). The college is within a less studied, rural area of Ladakh, North India. Research focusses on a case study (Students Educational and Cultural Movement of Ladakh (SECMOL) College), close to Leh, Ladakh, and extends to incorporate/apply thinking from/to the wider Ladakh region. The approach adopted, centring on the hazard assessment of a single entity/local area, allows a rapid uptake of hazard recommendations within a college environment planning to continue its existence for decades ahead. A sister paper (Petterson et al., 2019) documents the active involvement of college staff and students in the principles of geohazard assessment and the development of student-centric hazard assessments of the college and their home village. SECMOL is a self-sufficient, alternative, college, organised along strong environmentally sustainable principles. The paper aims to discuss these issues.

This work has adopted different strategies for different hazards. Fieldwork involved the collection of quantitative and qualitative data (e.g. shape and size of valleys/river channels/valley sides, estimation of vegetation density, measurement of sediment clasts, angle of slopes, assessment of sediment character, stratigraphy of floodplains and identification of vulnerable elements). These data were combined with satellite image analysis to: define river catchment character and flood vulnerability (e.g. using the methodology of Collier and Fox, 2003), examine catchment connectivity, and examine landslip scars and generic terrain analysis. Literature studies and seismic database interrogation allowed the calculation of potential catchment floodwater volumes, and the collation of epicentre, magnitude, depth and date of seismic events, together with recent thinking on the return period of large Himalayan earthquakes. These data were used to develop geological-seismic and river catchment maps, the identification of vulnerable elements, and disaster scenario analyses.

This research concludes that SECMOL, and much of the Ladakh region, is exposed to significant seismic, flood and landslide hazard risk. High magnitude earthquakes have return periods of 100s to c. 1,000 years in the Himalayas and can produce intense levels of damage. It is prudent to maximise earthquake engineering wherever possible. The 2010 Leh floods demonstrated high levels of devastation: these floods could severely damage the SECMOL campus if storms were centred close by. This study reveals the connectivity of catchments at varying altitudes and the potential interactions of adjacent catchments. Evacuation plans need to be developed for the college. Northern ridges at SECMOL could bury parts of the campus if mobilised by earthquakes/rainfall. Slope angles can be lowered and large boulders moved to reduce risk. This work reinforces recommendations that relate to building quality and urban/rural planning, e.g. using spatial planning to keep people away from high-risk zones.

The frequency of hazards is low, but potential impacts high to very high. Hazard mitigation actions include engineering options for hazardous slopes, buildings to be earthquake-proofed, and evacuation management for large floods.

Methodologies undertaken in this research are well-tested. Linkages between disciplines are ambitious and somewhat original. The application of this work to a specific college centre site with the capacity to rapidly take up recommendations is novel. The identification of catchment inter-connectivity in this part of Ladakh is novel. This work complements a sister paper (Petterson et al., 2019) for community aspects of this study, adding to the novelty value.

The “tourism living systems” (Tourism Living System – TLS) concept is underdeveloped, with limited relevant theoretical analysis to understand how it can support the transformations of tourism systems towards healthy communities and places. This paper aims to conceptualise TLSs and key stakeholder roles for enacting regenerative tourism using a living systems perspective.

Knowledge synthesis and co-production were used to identify the conceptual framework and its applications. Knowledge synthesis was undertaken through a scoping review of the regenerative tourism literature and supplemented by a consultation exercise with leading regenerative tourism practitioners. Co-production of knowledge involved case study research to assess the conceptual framework's practical applications and revise it with regenerative tourism practitioners.

The study revealed that regenerative tourism is informed by living systems' thinking. The authors identify five diverse, interdependent and interconnected stakeholder roles from the case studies and scoping review. All stakeholder roles are vital for constituting tourism systems that contribute to the healthy evolution of social-ecological systems.

Real-world case study applications of the TLS framework will guide tourism stakeholders who seek to adopt regenerative tourism approaches.

The study contributes to developing new frontiers in tourism stakeholder roles and paradigms with implications for regenerative tourism futures. The TLS framework challenges industrial conceptions of tourism by proposing a shift in stakeholder roles from extraction to generating new life to survive, thrive and evolve.

The aim of this paper is to assess the thinning notion in a case study while acknowledging the hybrid nature of regional identities with the past. In The Netherlands, a process can be observed in which regions actively claim their uniqueness to ensure their development and relevance. It seems that regions adopt similar modern labels in their regional marketing, suggesting a so-called thinning of identities away from traditional thick identities.

The paper is based on a content analysis of promotional texts and interviews with politicians to analyse the context, aims and perceptions of the regional marketing. It stresses an approach which sees identities as balanced between the present and the past.

In line with the thinning notion, this case study shows indeed a creation of new thin elements and an exclusion of traditional thick elements in the regional marketing. However, it was also found that the marketing entails creative links between both characteristics, which suggest a tempering of the thinning notion.

The results show that linking traditional with utilitarian elements might capacitate traditional regions to allocate the resources for regional marketing more effectively.

Despite the fact that studies acknowledge identities as neither thick nor thin, the thinning notion seems to examine both elements as a dichotomy within regions, which does not follow the nature of identities as interconnected in time. Then, the value of this study must be found in the way it goes behind such a dichotomy by presenting an integrative analysis of thin and thick characteristics.

Urban resilience is becoming increasingly important due to increasing degree of urbanization and a combination of several factors affecting urban vulnerability. Urban resilience is also understood as a capacity of a system to prepare, respond and recover from multi-hazard threats. The purpose of multi-risk approach (MRA) is to take into consideration interdependencies between multiple risks, which can trigger a chain of natural and manmade events with different spatial and temporal scales. The purpose of this study is to understand correlation between multi-risk approach and urban resilience.

To increase urban resilience, MRA should also include multi-risk governance, which is based on understanding how existing institutional and governance structures, individual judgments and communication of risk assessment results shape decision-making processes.

This paper is based on extensive fieldwork in the test studies of Naples, Italy and Guadeloupe, France, the historical case study analysis and the stakeholders’ interviews, workshops and focus groups discussions.

Multi-risk is a relatively new field in science, only partially developed in social and geosciences. The originality of this research is in establishment of a link between MRA, including both assessment and governance, and urban resilience. In this paper, the authors take a holistic and systemic look at the MRA, including all stages of knowledge generation and decision-making. Both, knowledge generation and decision-making are reinforced by behavioural biases, different perceptions and institutional factors. Further on, the authors develop recommendations on how an MRA can contribute to urban resilience.

This paper aims to empirically investigate time–frequency linkages between Euramerican mature and Asian emerging crude oil futures markets in terms of correlation and risk spillovers.

With daily data, the authors first undertake the MODWT method to decompose yield series into four different timescales, and then use the R-Vine Copula-CoVaR to analyze correlation and risk spillovers between Euramerican mature and Asian emerging crude oil futures markets.

The empirical results are as follows: (a) short-term trading is the primary driver of price volatility in crude oil futures markets. (b) The crude oil futures markets exhibit certain regional aggregation characteristics, with the Indian crude oil futures market playing an important role in connecting Euramerican mature and Asian emerging crude oil futures markets. What’s more, Oman crude oil serves as a bridge to link Asian emerging crude oil futures markets. (c) There are significant tail correlations among different futures markets, making them susceptible to “same fall but different rise” scenarios. The volatility behavior of the Indian and Euramerican markets is highly correlated in extreme incidents. (d) Those markets exhibit asymmetric bidirectional risk spillovers. Specifically, the Euramerican mature crude oil futures markets demonstrate significant risk spillovers in the extreme short term, with a relatively larger spillover effect observed on the Indian crude oil futures market. Compared with India and Japan in Asian emerging crude oil futures markets, China's crude oil futures market places more emphasis on changes in market fundamentals and prefers to hold long-term positions rather than short-term technical factors.

The MODWT model is utilized to capture the multiscale coordinated motion characteristics of the data in the time–frequency perspective. What’s more, compared to traditional methods, the R-Vine Copula model exhibits greater flexibility and higher measurement accuracy, enabling it to more accurately capture correlation structures among multiple markets. The proposed methodology can provide evidence for whether crude oil futures markets exhibit integration characteristics and can deepen our understanding of connections among crude oil futures prices.

In this chapter, we present our ongoing efforts in developing and sustaining interdisciplinary STEM undergraduate programs at North Carolina A&T State University (NCA&T) – a state-supported HBCU and National Science Foundation (NSF) Historically Black Colleges and Universities Undergraduate Program (HBCU-UP) Institutional Implementation Project grantee. Through three rounds of NSF HBCU-UP implementation grants, a concerted effort has been made in developing interdisciplinary STEM undergraduate research programs in geophysical and environmental science (in round 1), geospatial, computational, and information science (in round 2), and mathematical and computational biology (in round 3) on NCA&T campus. We first present a brief history and background information about the interdisciplinary STEM undergraduate research programs developed and sustained at NCA&T, giving rationales on how these programs had been conceived, and summarizing what have been achieved. Next we give a detailed description on the development of undergraduate research infrastructure including building research facilities through multiple and leveraged funding sources, and engaging a core of committed faculty mentors and research collaborators. We then present, as case studies, some sample interdisciplinary research projects in which STEM undergraduate students were engaged and project outcomes. Successes associated to our endeavor in developing undergraduate research programs as well as challenges and opportunities on implementing and sustaining these efforts are discussed. Finally, we discuss the impact of well-structured undergraduate research training on student success in terms of academic performance, graduation rate and continuing graduate study, and summarize many of the learnings we have gained from implementation and delivery of undergraduate research experiences at HBCUs.

Natural gas makes up about 50 per cent of Pakistan's energy consumption, which is decreasing at an alarming pace, making Karachi – the largest city of Pakistan – one of the major victims of natural gas shortfall. The purpose of this paper is to model natural gas demand and supply using geographic information systems.

Sui Southern Gas Company datasets were used to derive annual per capita gas usages and to analyze the capacity of gas supplies. Union Council is taken as a smallest and basic analytical administrative spatial unit for appraisal of badly affected, with insufficient, low and better gas supply regions.

Results show that the per capita demand for natural gas is higher in high class residential areas while supply is lowest for upper middle and lower middle class residential area populations. Only 19 per cent of the total residential areas are expected to be free from gas shortfalls. About 53 per cent of residential areas are facing the problem of low gas availability; and 3 per cent and 11 per cent areas are under stress of badly affected and insufficient gas supply, respectively.

This research shows an example of constructing a Geographic Information System (GIS)‐based gas demand and supply model that can be used for building strategic guidelines for top‐level planners, engineers and decision makers at the micro‐level. This is not a “deep” paper, but it works in identifying a problem and presenting a quantitative way forward. This paper will have significant impact both on society and academia, as this innovative technology and its implementation on gas utility has happened for the first time in Pakistan. Furthermore, in the international literature this has also been in infancy and will open new avenues of research, especially in developing countries. The work would certainly be applicable for other consumer‐based utilities such as electricity, telecommunication, sewerage and municipal water and they would all benefit from it substantially.

The study aims to explore the composition and microstructure of clay functionally graded materials under the process of double-gradient direct ink writing (DIW).

The investigation focused specifically on the pore characteristics of barite-kaolin clay composite after three-dimensional (3D) printing and sintering as well as its bionic application in geophysical model.

The model with pore and material variations brought about spatial and nonlinear mechanical properties. Moreover, the vertical gradient and connected pores in the upper kaolin part simulated the natural phenomenon of the landslide model (take Chinese Majiagou landslides as an example). Both the thermal debinding behavior and the kaolin powder particles characteristics [large pore volume (0.019 cm³g^–1) and pore size (29.20 nm)] were attributed to the interconnection channels.

Hence, the macroscopic and microscopic pores achieved by dual-gradient DIW process make it possible to control the permeability and details of properties, precisely in the geological model.
