The public debt sustainability and its determinants in Sub-Sahara African countries

PurposeThis paper aims to answer the following important questions: Is public debt in Sub-Saharan African (SSA) countries sustainable? What are the determinants of public debt sustainability in these countries, and do these determinants exhibit heterogeneity due to regional, natural resource, and income differences among SSA countries?Design/methodology/approachThis study analyzes the public debt sustainability in SSA countries using the theoretical model known as the Present Value Budget Constraint (PVBC) model developed by Hamilton and Flavin (1986), and adopts the econometric testing method proposed by Trehan and Walsh (1991). Moreover, to empirically investigate the determinants of public debt sustainability in SSA countries, the System-Generalized Method of Moments (System-GMM) method is applied. Furthermore, this study conducts heterogeneity analysis by categorizing the sample based on different regions, natural resource endowments, and income levels. The data of this study are sourced from the IMF and World Bank databases for 45 SSA countries from 2005 to 2021.FindingsFindings reveal that public debt in SSA countries is not sustainable in the long run, with factors such as the previous government debt, long-term debt ratio, debt repayment capacity, economic growth rate, inflation rate, export to GDP, and government fiscal deficit rate influencing sustainability. Additionally, the factors exhibit heterogeneity attributed to regional, natural resource, and income variations among SSA countries.Practical implicationsThe findings of our study will serve as a catalyst for policymakers in the SSA countries to embrace and sustain robust fiscal consolidation and debt stabilization measures. Moreover, countries with distinct characteristics should implement tailored approaches. Additionally, policymakers in SSA countries should implement economic measures to address public debt issues. These measures include improving the macroeconomic structure, promoting economic transformation and diversification of industries, fostering sustainable economic growth, ensuring price stability, and strengthening resilience against external shocks and debt risks. Specifically, countries endowed with indigenous species, resources, and tourism potential should adopt a well-coordinated strategy that utilizes agriculture, tourism, ecotourism, and the hospitality industry as instruments for sustainable local community and rural development.Originality/valueFirstly, it assesses the sustainability of public debt and its determinants for countries in SSA, which distinguishes it from previous studies that only focus on either debt sustainability or determinants of debt separately. Secondly, by including multiple SSA countries in the analysis, this study stands out from prior research that predominantly concentrates on specific nations. Thirdly, the utilization of the System-GMM method for analyzing determinants adds a novel dimension to this study, departing from earlier literature primarily focused on debt thresholds. Lastly, the heterogeneity analysis conducted in this study provides an empirical foundation for tailoring policies to different countries, addressing a facet often overlooked in earlier literature.

The results concluded that tourism development could significantly contribute to economic growth in the province of Zambales through creating new business opportunities to improve standard of living of the community by providing employment. In this regard, in order to improve the current situation of tourism industry, Strategic Development Plan for Sustainable Tourism is proposed. Provincial government of Zambales must design and formulate programs to integrate tourism requirements into all levels of local government unit and would have to take a visionary local government official who has the grit to literally fight for a well-defined and managed tourism industry because it is a chance for municipalities to move up through the help of tourism, yet it requires the cooperation or input of every social and institutional organization such as stakeholders. Therefore, planning for the development of tourism based on sustainable economic development, growth and prosperity of local communities can be effective.

Synergistic Integration of EVs and Renewable DGs in Distribution Micro-Grids

This paper proposes a multi-objective optimization framework for safe, reliable, and economic integration of electric vehicles (EVs) and renewable distributed generators (DGs) in distribution micro-grids. EV and DG coordination optimization with the use of vehicle-to-grid (V2G) technology along with system reconfiguration optimization is developed to provide collective revenues and address integrational complications that may occur by additional system loading due to EV charging and EV-DG energy exchanges. A Genetic Algorithm (GA) optimizes the EV charging/discharging in synergies with renewable DGs to maximize benefits that can be captured by their collaborative participation in electricity market and through renewable energy arbitrage. The developed EV charging/discharging optimization is implemented in a real 134-bus distribution network and is evaluated for its potential operational implications, namely, increased system losses. A system reconfiguration is then proposed to reduce the system losses by optimizing the flow of power through switching on/off the connections within the micro-grid and/or with other distribution systems. Simulation results demonstrate the efficiency of the proposed method in not only providing collective revenues, but also in enhancing the system operation by reducing the losses of the distribution grid. The collective benefits proposed by the developed optimization and validated by the simulation results facilitate transitioning to clean and eco-friendly sources of energy for generation and transportation, which in turn leads to more sustainable development of societies and communities.

Achieving a Water-Resilient Rotterdam: Past, Present and Future Perspectives

Rotterdam has a close and essential connection with water, both as a port city and a delta city. As a low-lying city situated in the estuary of the Rhine and Meuse rivers, most of the city (85 per cent) lies below sea level, and some areas are as low as 7 m beneath sea level. Except for the main port area, the remaining 15 per cent of the city lies in outer dike zones. Since evacuation is nearly impossible, adapting to climate change presents a significant challenge. This vulnerable delta city is continually revisiting its approach to water threats and climate change is demanding a new round of interventions. The historical fight against water is being abandoned in favor of living with water. Water connects and brings leverage. By creating more space for water and promoting blue-green infrastructure in the built environment, Rotterdam is becoming climate-resilient, greener and more livable. Rotterdam’s blue-green transformation to a sponge city of the future (2100) aims at achieving SDG 11 (“Sustainable Cities and Communities”) and has the potential to fulfill targets regarding climate action (SDG 13), the protection of water quality (SDG 6) and the restoration of biodiversity (SDG 14 and 15).

Empowering Farmers to Enhance Water Use Efficiency: Innovative Practices in SSPC

The Sardar Sarovar project, featuring a gravity dam on the Narmada River in Gujarat, stands as one of the largest in terms of concrete volume globally. This study investigates the project's extensive canal network and its impact on agricultural productivity in the command area. Covering a vast expanse across multiple states, the project's irrigation allocation and water management strategies are examined. Special attention is given to addressing soil degradation issues, particularly salinity, and implementing farmer-centered interventions to enhance water use efficiency. Methodologies include land rejuvenation efforts, reclamation of salt-affected land, participatory irrigation management, and promoting improved agricultural practices. Results indicate successful mitigation of soil degradation and increased crop yields through strategic interventions like cotton-castor relay cropping which has demonstrated a 1.5-fold increase in income compared to sole cropping. Intercropping with isabgul/ajwain, and implementing deficit irrigation have resulted in a substantial 43% increase in overall yield, particularly in cumin cultivation. Farmers have also embraced innovative water-saving techniques, such as alternative furrow irrigation and strategic timing of irrigation during critical growth stages, resulting in water savings of 30-35%. However, challenges remain in achieving widespread adoption of participatory irrigation management practices. The study concludes with insights into the necessity of sustained social engineering efforts and community engagement for long-term water resource management and agricultural sustainability in the project area.

The Role of Local Community in Enhancing Sustainable Community Based Tourism

The emergence of “community-based tourism” (CBT) is seen as a viable and alternative means of promoting sustainable tourism development, enhancing community welfare, as well as empowering local communities. By actively involving and empowering the local community, this tourism model aims to minimize negative social, cultural, and environmental impacts while fostering economic benefits for the community. In recent years, there has been a growing recognition of the pivotal role played by local communities in the success and sustainability of community-based tourism initiatives. Therefore, a systematic review is conducted to investigate the multifaceted contributions of the local community to sustainable community-based tourism. The researcher examined relevant peer-reviewed articles, books, and reports published in English between 2000 and 2022, focusing on the role of local community in enhancing sustainable community-based tourism. The search was performed in important databases such as Google Scholar, Tandfonline, and ScienceDirect, resulting in a total of 965 publications. After applying removing duplicates and inclusion criteria, only 30 articles out of 152 full articles met the requirements. This thorough and systematic review concludes that active participation of the local community in decision-making processes positively impacts sustainable “community-based tourism”. The findings highlight that the local community acts as a key stakeholder in decision-making processes, ensuring that tourism development aligns with community values and aspirations.

Climate-responsive design practices: A transdisciplinary methodology for achieving sustainable development goals in cultural and natural heritage

The 17 Sustainable Development Goals (SDGs) defined by the United Nations represent a blueprint for the adoption of global practices and policies to foster sustainability in societies and increase efficiencies in resources uses. The Italian National Trust, FAI, has embraced these goals, developing a holistic and transdisciplinary methodology to promote a more sustainable approach to preserve its natural and built heritage. This methodology combines heritage protection with the SDGs in various macro-areas of interventions, including energy, water, biosphere, responsible consumption, and sustainable communities. The aim is to increase access to affordable and clean energy, reduce water, waste, and soil footprints, promote responsible consumption, and develop human capital. The paper proposes a set of strategies to achieve the SDGs in heritage, involving the collaboration of several stakeholders, ranging from institutions to citizens. The methodology is applied to a specific Italian case study, Casa Macchi in Morazzone, to highlight the challenges in achieving the dual objective of preserving the historic building and promoting sustainability in the built environment.

Implication of Institutional Frameworks Governing Land Tenure Security in Social-Economic Dynamics: Experience from Iringa District in Tanzania

Purpose: The study aimed to examine the implication of institutional frameworks governing land tenure security in socioeconomic dynamics in the Iringa district. The study used the case of the Iringa district to investigate the institutional framework that provides implications for the governance of land tenure security in Tanzania. Methodology: The study employed phenomenography by collecting primary data from 16 key informants selected from village and district levels. Data from key informants were complemented by documentary review with perception considered deductively.   Findings: Findings confirmed the existence of two principal institutional frameworks; the Land Act No. 5 of 1999 and the Village Land Act No. 4 of 1999. Nonetheless, bureaucracy, inadequate policy dissemination, and poverty emerged as primary causes of deviations in land policy implementation in the study area. This study concludes that the successful implementation of Tanzania's land policy in the Iringa District Council has significantly facilitated land tenure security through the issuance of a Certificate of Customary Right of Occupancy. Establishing a robust institutional framework and clear land use rules has been central to this success. However, challenges such as complex Certificate of Customary Right of Occupancy acquisition procedures, bureaucracy, inadequate policy dissemination, and prevalent poverty in rural areas have been identified as impediments. Unique Contribution to Theory, Practice and Policy: The study was guided by Institutional Theory which describes the interaction of human beings with existing natural resources, the institution involves the regulation of formal rules from constitutions, status laws, and other legal frameworks controlling the interaction and relationship of human behavior. The study contributed to the theory by establishing the relationship between the organization and enforcement of policy and regulatory framework that governs land tenure. Also, the study recommends expanding the Certificate of Customary Right of Occupancy issuance, strengthening local land administration, simplifying land use regulations, facilitating easier access to Certificate of Customary Right of Occupancy especially for impoverished households, and implementing strategies to reduce bureaucracy and enhancing policy understanding at the grassroots level. These measures aim to enhance land tenure security and support sustainable development in rural communities.

A fuzzy synthetic evaluation approach to assess the risks associated with municipal waste management: Implications for sustainability

The rapid growth of industry, urban areas, and populations has substantially increased waste production worldwide. The inadequacy of robust waste management systems and limited resources poses significant challenges for many emerging economies, including Bangladesh, resulting in environmental contamination. Despite numerous academic studies on sustainable waste management, there is a noticeable gap in the literature concerning identifying, evaluating, and modeling critical risks associated with adopting sustainable municipal waste management systems, particularly in emerging economies like Bangladesh. This study, therefore, aims to fill this gap by identifying, categorizing, and assessing the crucial risks in implementing sustainable municipal waste management systems. Through an extensive review of existing literature and validation with expert feedback, this study employs a fuzzy synthetic evaluation method-based framework to prioritize the identified risks. The study calculates the probability of occurrence and degree of impact values to provide decision-makers with insights into the severity of different risk categories, aiding in case-by-case attention. Scores assigned on a 1 to 5 scale range from 2.59 to 4.14 for the various risk categories. Notably, ”Industrial challenges related” and ”Community and infrastructure requirements related” emerge as the most significant risk categories among those analyzed. This study contributes to the existing literature by employing fuzzy synthetic evaluation, a methodology rarely used to determine critical risks in municipal waste management. Furthermore, it is poised to offer valuable insights to industrialists and waste management authorities, empowering them to develop responsive strategies and contribute to the sustainable development of cities and urban communities.

Quality Perception of Short Food Supply Chains Products: From the Producer’s to the Consumer’s Point of View

Short food supply chains (SFSCs) are a still developing phenomenon in the world of food production and distribution. They involve a direct connection between local farmers and consumers, with minimal intermediaries involved. SFSCs have gained significant interest in recent years due to their potential to promote sustainable agriculture and support local communities. As a result, many governments, organisations, and individuals have been exploring ways to develop and promote these chains as a viable alternative to conventional food supply chains. However, it is still unclear how SFSCs products are perceived differently by producers and consumers: what makes SFSCs products more desirable? Starting from a European project (SmartChain), answers from twenty questionnaires from SFSCs actors across Europe were analysed to understand the strengths and weaknesses of SFSCs products according to the producers. From their answers, 18 quality criteria referred to SFSCs products were obtained and then proposed to consumers through a second questionnaire. The second questionnaire aimed to better understand whether the producers’ points of view matched the consumers’ points of view. From the analysis of the results, it was possible to understand what criteria were considered quality attributes by producers and consumers. Organic production and the presence of both trained and vulnerable personnel were not particularly relevant to the quality perception of SFSCs products. The storage method, the assortment range, and the processing of the products were not evaluated as quality criteria. The consumers who were interviewed perceived the quality of a food product coming from an SFSC linked to the characteristics of the social context of the product. They associated products sold in SFSCs with non-processed food. Overall, such a survey can be considered a useful tool to deepen our knowledge about short food supply chains and offers several ideas for further studies and analysis.

Towards a circular economy and just transition to net-zero in rural Scotland: Resident perspectives on policy and practice

The circular economy and just transition are key dimensions of the sustainability challenges of the 21st century. These concepts are ambiguous and meanings differ among actors, sectors and contexts. This paper examines the circular economy and a just transition to net-zero in the Scottish context, where both are prominent in national policy discourses and central to the work of Zero Waste Scotland. It is based on qualitative research, co-designed with Zero Waste Scotland, to explore how rural residents in Scotland understand the circular economy and just transition, in their everyday lives and communities. This is an under-researched area and our findings add new knowledge useful for implementing sustainability policies in a rural context. Focus groups were carried out in three rural areas, engaging with a range of residents in a deliberative setting. The findings support the need for a more collaborative, whole systems approach that moves beyond siloed thinking and which focuses on local capacity and knowledge building for transitions to more sustainable rural communities.

Decarbonization through Smart Energy Management: Climate Control in Building-Integrated Rooftop Greenhouses for Urban Agriculture Across Various Climate Conditions

This paper investigates the potential benefits of integrating rooftop greenhouses (RTGs) with buildings to reduce energy and CO2 costs, contributing to urban decarbonization efforts. This integration not only advances sustainable urban agriculture but also aligns with the United Nations Sustainable Development Goal 7 (SDG7) - Affordable and Clean Energy, and Sustainable Development Goal 11 (SDG11) - Sustainable Cities and Communities, through its energy-efficient, low-carbon approach. We hypothesize that this integration can significantly lower energy use in integrated RTGs (i-RTGs) and set out to validate this through dynamic models for both building and i-RTG climates, focusing on CO2 concentration, humidity, and temperature. Central to our approach is the implementation of a nonlinear model predictive control (NMPC) framework, which utilizes these dynamic models to make control decisions aimed at minimizing total control costs. This framework operates in a receding horizon procedure, regulating climate factors within the i-RTG and building using various actuators. We validate our approach by simulating an i-RTG atop a building in eleven different cities, demonstrating interactions such as energy, moisture, and CO2 exchange. Significantly, our study reveals that integrating i-RTG with buildings under the NMPC framework leads to a 15.2% reduction in control costs. Additionally, we find that the i-RTG model is adaptable to different climates, with colder regions showing greater cost reduction potential. Our study underscores the viability and advantages of integrating i-RTGs with buildings, offering a sustainable, decarbonizing solution for urban agriculture and building management that contributes to the fulfillment of SDG7 and SDG11.

Exergy destruction within a centrifugal water pump

Understanding the loss generation mechanisms in water pumps is a vital step in decarbonising our built environment, and achieve sustainable cities and communities. In this paper, loss generation mechanisms in a centrifugal pump are quantified by performing exergy analysis with unsteady Reynold Averaged Navier Stokes simulations (uRANS). Exergy analyses are performed at various operational conditions for a commercially available pump and its ideal version that has zero surface roughness. Numerical results are used to derive mathematical expressions to describe exergy destruction rates as functions of normalized flow rates. These expressions provide insight on how and where losses are generated within a centrifugal pump, and how loss generation mechanisms are affected by the flow rate. Results show that 80% of the losses are generated within the impeller, intersection and volute, whereas secondary flows through the deadzone and leakage paths have insignificant contribution to the total losses even though mass flow rate through these paths are considerable. The exergy destruction rate equations derived here, have the potential to replace the semi-empirical estimations of losses in traditional turbomachinery design methodologies and serve as a tool to develop a novel knowledge-based turbomachinery design methodology.
