Deepor Beel is one of the Ramsar Site and a wetland of great biodiversity, situated in the south-western part of Guwahati, Assam. With urban development at its forefront city of Guwahati, Deepor Beel is under constant threat. The study aims to calculate the lake water volume from the water surface area and the underwater terrain data using a triangulated irregular network (TIN) volume model.

The lake water surface boundaries for each year were combined with field-observed water level data to generate a description of the underwater terrain. Time series LANDSAT images of 2001, 2011 and 2019 were used to extract the modified normalized difference water index (MNDWI) in GIS domain.

The MNDWI was 0.462 in 2001 which reduced to 0.240 in 2019. This shows that the lake water storage capacity shrank in the last 2 decades. This leads to a major problem, i.e. the storage capacity of the lake has been declining gradually from 20.95 million m³ in 2001 to 16.73 million m³ in 2011 and further declined to 15.35 million m³ in 2019. The fast decline in lake water volume is a serious concern in the age of rapid urbanization of big cities like Guwahati.

None of the studies have been done previously to analyze the decline in the volume of Deepor Beel lake. Therefore, this study will provide useful insights in the water resource management and the conservation of Deepor Beel lake.

This study aims to describe the role of knowledge diffusion in evolving governance principles for Islamic banking.

This study develops a discursive theoretical debate using the discourse analysis method on the Sharīʿah principles related to interest (Riba), excessive uncertainty (Gharrar) and profit and loss sharing and their convergence with the conventional banking principles of profitability, solvency and liquidity.

The study proposes a novel framework that describes how knowledge diffusion bridge-up the Sharīʿah and banking principles in terms of integration of banking principles by Sharīʿah scholars, integration of Sharīʿah principles by managers and the resultant, emergent principles for the governance of Islamic banking.

The proposed framework can inform professionals on how knowledge of banking practices and Sharīʿah can help them in governing Islamic banking. The Board of Directors may adopt a holistic approach for encouraging enhanced interactions between Sharīʿah scholars and managers. Such interaction may be increasing harmony, reducing conflicts and better coordination resulting in Sharīʿah-compliant and market wise viable products and services, thus increasing banking profitability.

This is the first study, which acknowledges and illustrates the role of the knowledge diffusion process in evolving governance principles for Islamic banks. This paper contributes to the theory of corporate governance by using the knowledge, aptitude and practice theory lens to examine conceptually how Islamic banking governance principles emerged through the knowledge diffusion process.

The study aims to explore the validity of the modern renewable energy-environmental Kuznets curve (REKC) while considering the relevance of financial development in the consumption of modern renewable energy in East Africa Community (EAC). Modern renewable energy in this study includes all other forms of renewable energy except traditional use of biomass. The authors controlled for the effects of urbanization, governance, foreign direct investment (FDI) and trade openness.

Panel data of the five EAC countries of Burundi, Kenya, Rwanda, Tanzania and Uganda for the period 1996–2019 were used. The analysis relied on the use of the autoregressive distributed lag–pooled mean group (ARDL-PMG) model, and the data were sourced from the World Development Indicators (WDI), World Governance Indicators (WGI) and International Energy Agency (IEA).

The REKC hypothesis is supported for modern renewable energy consumption in the EAC region. Financial development positively and significantly affects modern renewable energy consumption, whereas urbanization, FDI and trade openness reduce modern renewable energy consumption. Governance is insignificant.

The concept of the REKC, although explored in other contexts such as aggregate renewable energy and in other regions, has not been used to explain the consumption of modern renewable energy in the EAC.

This study aims to investigate the relationship between management support, quality infrastructure, staff training and the effectiveness of quality enhancement cells (QECs) established in higher education institutions.

Data were acquired via a structured questionnaire dispatched to faculty members across 12 public and private universities, primarily situated in Punjab, Pakistan. Among the 200 questionnaires distributed, 180 were retrieved and 140 were deemed valid. The proposed relationships were examined using SPSS–25 and PLS–SEM.

The results show a positive and significant relationship between management support, quality infrastructure and staff training with QECs' effectiveness. The study also highlights that the effectiveness of QECs is “Good” in only two of the 12 universities, while in most universities it is “Barely Acceptable”. Furthermore, QECs' effectiveness is slightly better in public universities compared to private institutions.

The study employs convenience sampling and a cross-sectional approach, focusing on faculty members from 12 universities, primarily in Punjab, Pakistan. To enhance future research, larger samples and probability-based sampling should be considered, while involving quality managers and students for a broader perspective.

The research suggests policymakers and university leaders should strengthen their support by providing resources, quality infrastructure and training for academic and administrative staff. This would enhance the effectiveness of QECs and improve the overall quality of education in both public and private universities.

This study contributes to the literature on quality assurance in higher education by emphasizing the significance of QECs concerning management support, quality infrastructure and staff training – areas that are often overlooked in Pakistani universities.

This paper aims to recommend a framework that serves as a practical work tool for conducting risk-based Shari’ah audit (RBSA) in Islamic financial institutions (IFIs).

Qualitative research method was used through critical in-depth content analysis of documented literature to generate deep insights, further supported with a hypothetical illustrative case study application of the framework on an Islamic bank, aimed at bringing the framework to a practical, near real-life scenario.

A robust RBSA framework has been developed which focuses on Shari’ah non-compliance risks to systematically and practically arrive at a rated opinion on the level of an IFI’s adherence with Shari’ah rules and principles as recommended by the Accounting and Auditing Organization for Islamic Financial Institutions, aimed to safeguard the IFI and promote financial system stability at large.

Practical realities limited the study to the use of a hypothetical case study bank. Future researchers can apply the framework to a real case study of diverse IFIs for effective contextual recalibration in diverse jurisdictions.

This paper aids the development of both internal and external Shari’ah audit practice using the risk-based approach.

The RBSA framework contributes to promoting public trust and confidence in the Islamic finance industry.

This paper has proposed this RBSA framework as a practical work tool for Shari’ah auditors in their engagements and regulators in promoting sound governance and financial system stability. It provides foundation for future researchers in the field.
