The aim of this paper is to determine whether the dominant integrated water resources management (IWRM) paradigm within which the Pra River Basin is managed holds the key to address the current water security and sustainability issues in Southwestern Ghana.

This study employed a literature review developed based on water security and sustainability studies as well as normative scenarios from the broad scenario planning methodology. The study builds on Wæver’s Theory of Securitization and the Utilitarian theory to protect water bodies through the use of artificial intelligence (AI).

Insights on introducing innovative environmental sustainability technology are presented and propose the Pra-integrated smart water security management decision-making system that uses visual inspections, noise sensors, the potential of hydrogen (pH) probe sensor, real-time collection of hydrological data (streamflow) and wireless transmission of the data in real-time at the basin level. This serves as a robust tool for managing the basin’s sustainable development ecosystem by using AI to protect water bodies against illegal mining.

The proposed innovative environmental technology which is the first of its kind is meant to gain a better understanding of pollution incidents and respond quickly to them by integrating AI and Internet of Things (IoT) technologies with traditional IWRM practices. This addresses water security in the Pra Basin, supports policy development and innovation, strengthens the goal of the government to protect water resources against pollution and contributes to the African Water Vision and the United Nations’ Agenda 2030 Sustainable Development Goals 3 and 6.

This study aims to assess the effects of natural disasters on food security in a sample of 40 sub-Saharan African countries. First, the authors assess the effects of natural disasters on the four dimensions of food security and second, the authors disaggregate natural disaster using the two dimensions that are most representative, namely, hydrological and biological disasters.

The regressions are based on the generalised method of moments on a data set covering the period 2005–2020. Natural disasters are measured by the total number of people affected and food security by its characteristics: access, availability, use and sustainability.

The results show that natural disasters increase the prevalence of undernourishment but reduce dependence on cereal imports. An increase in natural disasters by 1% increases the prevalence of undernourishment by the same proportion. As for import dependency, a 1% increase in natural disasters reduces dependency by 2.2%. The disaggregated effects show that hydrological disasters are more significant than biological disasters in impacting food security. Floods reduce the average energy supply adequacy but also dependence on cereal imports. Policy implications are discussed.

The study complements the extant literature by assessing the effects of natural disasters on food security in a region where food insecurity is one of the worst in the world.

Authorities have set up numerous security checkpoints during times of armed conflict to control the flow of commercial and humanitarian trucks into and out of areas of conflict. These security checkpoints have become highly utilized because of the complex security procedures and increased truck traffic, which significantly slow the delivery of relief aid. This paper aims to improve the process at security checkpoints by redesigning the current process to reduce processing time and relieve congestion at checkpoint entrance gates.

A decision-support tool (clearing function distribution model [CFDM]) is used to minimize the effects of security checkpoint congestion on the entire humanitarian supply network using a hybrid simulation-optimization approach. By using a business process simulation, the current and reengineered processes are both simulated, and the simulation output was used to estimate the clearing function (capacity as a function of the workload). For both the AS-IS and TO-BE models, key performance indicators such as distribution costs, backordering and process cycle time were used to compare the results of the CFDM tool. For this, the Kerem Abu Salem security checkpoint south of Gaza was used as a case study.

The comparison results demonstrate that the CFDM tool performs better when the output of the TO-BE clearing function is used.

The efforts will contribute to improving the planning of any humanitarian network experiencing congestion at security checkpoints by minimizing the impact of congestion on the delivery lead time of relief aid to the final destination.

The COVID-19 pandemic, starting in early 2020, has significantly compromised global commitment to the 2030 Agenda for Sustainable Development Goals, notably affecting areas like food security (SDG 2) and the economy (SDG 8). Informal economy platform employees have been among the most impacted. In India alone, 7.7 million workers in the informal economy have suffered, with nearly 90% of unskilled and semi-skilled workers experiencing income loss. The widespread income loss among a significant portion of the workforce has led to disruptions in demand and supply mechanisms, thereby worsening food insecurity. This study investigates the determinants of the food consumption score (FCS) to serve as an indicator of food security within informal-economy households. A longitudinal survey of 2,830 unskilled and semi-skilled employees, including drivers, domestic workers, delivery personnel, beauticians, street vendors, small business owners, and self-employed individuals, was conducted. The findings show a significant shift towards borderline household FCS during the pandemic, with a sharp decline in daily consumption of dairy products and non-vegetarian items, indicating reduced protein intake. Consuming two or fewer meals per day increases the likelihood of poor FCS, highlighting the need for systematic interventions to ensure three regular meals per day. Moreover, insufficient government support for adequate food intake in informal economy households calls for redesigned assistance programs. Policymakers should prioritize practical solutions, such as community-based food distribution centers and mobile food vans, to ensure the delivery of nutritious food to vulnerable populations in Bangalore.

The purpose of this study is to explore the contributions of peace and security to the self-development of educators in Syria. It focuses on understanding how these elements impact the equitable distribution of benefits, treatment, facilities and resources. The study aims to uncover the intricate relationship between a secure, peaceful educational environment and the personal and professional growth of educators, thereby shedding light on how these factors synergistically enhance the educational landscape in Syria.

This study employs the Partial Least Squares Structural Equation Modelling (PLS-SEM) method for data analysis. Data were gathered through an online survey distributed to 472 Syrian educators from 14 provinces. The questionnaire, provided in Arabic, consisted of sections on demographics, peace and security, religion and cultural values, core values for self-development and government intervention. The data were analysed using IBM SPSS for descriptive analysis and PLS-SEM for causal effect analysis, allowing for the modelling of latent variables and handling non-normality in small to medium-sized samples.

The study found a positive correlation between peace and security, government intervention and self-development among Syrian educators. However, government intervention was identified as a poor moderator due to the unfavourable connection between past government actions and current expectations. The findings challenge the government to be proactive in addressing issues and concerns related to fair treatment and creating a harmonious academic environment. Educators seek equality in support and assistance across various academic activities for their self-development.

The study’s primary limitation is the use of convenience sampling, as the researchers faced difficulties in disseminating the questionnaires due to being non-local. This might affect the generalizability of the findings. Future research could employ a more randomized sampling method and expand the scope to include more diverse educational settings. The implications of this study are significant for policymaking, suggesting that targeted government interventions are necessary to foster a supportive and secure environment for educators.

The study underscores the need for more effective government policies that prioritize peace and security in educational settings. These interventions are crucial for the well-being and development of educators, ultimately improving educational quality in Syria. Practical recommendations include continuous support for educators through professional development programmes and equitable distribution of resources. By fostering a supportive environment, educators can better contribute to the educational sector and broader societal development.

By highlighting the critical role of peace and security in educators' self-development, the study contributes to broader social stability and cohesion. It advocates for policies that address the diverse needs and challenges faced by educators in Syria, ensuring they are well-supported in their roles. Enhancing educators' well-being and effectiveness can lead to improved educational outcomes, benefiting students and contributing to the nation’s long-term social and economic development.

This study provides a unique contribution by focusing on the nexus of peace, security and self-development among educators in Syria, an area previously underexplored. The findings offer valuable insights into the specific challenges and needs of educators in a conflict-affected region. The research emphasizes the importance of a peaceful and secure educational environment for the professional growth of educators, offering a foundation for future studies and policy discussions aimed at enhancing the educational landscape in Syria.

Cryptoassets are a diverse category of digital assets that rely on blockchain technology. They encompass various categories, such as cryptocurrencies, utility tokens, security tokens, tokenized assets and securities, and stablecoins. Cryptocurrencies are decentralized digital units of value that enable secure and transparent transactions. Utility tokens provide access to specific services or products within a blockchain network. Security tokens offer rights and entitlements similar to traditional securities, representing ownership in real-world assets or participation in investment opportunities. Tokenized assets and securities are digital representations of tangible or intangible assets, allowing for fractional ownership and enhanced liquidity. Stablecoins are blockchain-based digital assets designed to maintain a stable value, often pegged to fiat currencies or physical assets. This chapter examines each category's characteristics, benefits, and risks; explores their implementations and current applications in the fintech ecosystem; and discusses relevant regulations and future development opportunities.

The spatial–temporal conflicts in the construction process of concrete arch dams are related to the construction quality and duration, especially for pouring blocks with a continuous high-strength and high-density construction process. Furthermore, the complicated construction technology and limited space resources aggravate the spatial–temporal conflicts in the process of space resource allocation and utilization, directly affecting the pouring quality and progress of concrete. To promote the high-strength, quality-preserving and rapid construction of dams and to clarify the explosion moment and influence degree of the spatial–temporal conflicts of construction machinery during the pouring process, a quantification method and algorithm for a “Conflict Bubble” (CB) between construction machines is proposed based on the “Time–Space Microelement” (TSM).

First, the concept of a CB is proposed, which is defined as the spatial overlap of different entities in the movement process. The subsidiary space of the entity is divided into three layered spaces: the physical space, safe space and efficiency space from the inside to the outside. Second, the processes of “creation,” “transition” and “disappearance” of the CB at different levels with the movement of the entity are defined as the evolution of the spatial–temporal state of the entity. The mapping relationship between the spatial variation and the running time of the layered space during the movement process is defined as “Time–Space” (TS), which is intended to be processed by a microelement.

The quantification method and algorithm of the CB between construction machinery are proposed based on the TSM, which realizes the quantification of the physical collision accident rate, security risk rate and efficiency loss rate of the construction machinery at any time point or time period. The risk rate of spatial–temporal conflicts in the construction process was calculated, and the outbreak condition of spatial–temporal conflict in the pouring process was simulated and rehearsed. The quantitative calculation results show that the physical collision accident rate, security risk rate and efficiency loss rate of construction machinery at any time point or time period can be quantified.

This study provides theoretical support for the quantitative evaluation and analysis of the spatial–temporal conflict risk in the pouring construction process. It also serves as a reference for the rational organization and scientific decision-making for pouring blocks and provides new ideas and methods for the safe and efficient construction and the scientific and refined management of dams.

The study responds to the calls for multilevel approaches in entrepreneurship research and seeks to answer whether the relationships between personal values and entrepreneurship remain stable across different economic conditions, using the unemployment rate as a moderator. It pays attention to the solo self-employed and women, as these groups are particularly vulnerable when crises occur.

We use Schwartz's theory of human values, which has been understudied in entrepreneurship and follow a correlational research design with micro and macro variables. Multilevel logistic regression is applied to the data from the large sample of 151,032 individuals participating in six waves of the European Social Survey. Solo self-employed are distinguished from those employing others, and analyses are run separately for men and women to understand gender differences.

The findings show that self-direction and achievement are positively, and benevolence and security negatively related to entrepreneurship. The high unemployment rate lowers the positive relationships with self-direction and achievement and mitigates the negative relationship with security, but only for the solo self-employed and not for employers. Results mostly hold for both genders.

The study suggests that security-related values should not be omitted from entrepreneurship research focused on entrepreneurs' values. It also emphasizes the need to distinguish between various subgroups of entrepreneurs and their motivation, which is important for efficient active labor market policies.

The study utilizes multilevel analyses that account for individual- and country-level influences on entrepreneurial activity. It contributes to understanding how economic context influences value salience and supports the applicability of Schwartz's theory of human values in entrepreneurship.

Specialists of all pundits and ideologies held the thesis that tourism safety and security is a cornerstone for the evolution and development of tourism. Tourists very well occupy a central position in the engineering of the tourist system. For decades, the discipline was influenced by what experts dubbed as the bubble model which means that tourists should be physically isolated from the interaction with local people. This happens because local people tend to attack or harm high-purchasing power tourists. Some studies have overtly alerted on the risks of enclave tourism for the local economy and society. At the end of the 20th century, this paradigm set the pace for other theories that focused mainly on terrorism, political violence, and local crime. Even Embassies report to their citizens alerting them on what are the safe and unsafe zones to be visited or avoided. Having said this, the literature is not contemplating a new global phenomenon mainly marked by homeless people and their contact with tourist zones. Some works allude to the term homeless tours to denote the complex relationships between foreign tourists, the local government, and homeless young people. This chapter fills the gap while discussing in depth this slippery matter.
