Abstract

The present research compares and contrasts the legal institutional framework of the disaster management system between India and Indonesia. The primary objective of this research is to assess the efficiency and effectiveness of the disaster management frameworks of both countries, identifying their strengths and weaknesses, and suggesting potential improvements to the existing system. The introduction part of the study presents an overview of disaster management efforts worldwide and in Asia, followed by a literature review of several studies conducted to evaluate the efficiency and effectiveness of disaster management frameworks in various countries. The second part of the study presents a holistic overview of the disaster management systems in India and Indonesia, including disaster profiles, disaster risk and vulnerability, disaster preparedness, response, mitigation, and recovery strategies, as well as the legal and institutional frameworks of both countries. The research reveals that both nations should move beyond merely managing the risk. They should associate and integrate climate change adaptation strategies with disaster risk reduction. The research work set the stage for a deeper exploration of the complexities, innovations, and collaborations necessary to navigate the dynamic landscape of disaster risk and climate change adaptation in India and Indonesia.

Abstract

In Burkina Faso, Law No. 008-2023/ALT of June 20, 2023, on private real estate development includes restrictions that prevent private real estate developers from promoting land. However, almost two-thirds of these actors were engaged in this activity alone. This document therefore proposes to analyze the effects of this new legislative framework on actors involved in private real estate development in Burkina Faso. To this end, it draws mainly on qualitative data collected as part of a thesis in progress since 2021 from real estate developers, landowners, village development advisors (VDAs), sales agents, and plot buyers. Through content analysis, the article demonstrates that the revision of the legislative framework for private real estate development in Burkina Faso has led to land insecurity surrounding plots developed by private real estate developers, as well as pressure on these actors, who are struggling to make their land investments profitable. This law also affects sales agents who were speculating on land and landowners who no longer have fields to cultivate and are left with plots that are almost unattractive to customers. The results of this research call on the State to revise the texts governing land management and to strengthen control over the activities of private real estate developers.Received: 2024-11-24 Revised: 2025-08-15 Accepted: 2025-10-07 Published: 2025-11-10

Abstract

Spatial interpolation methods, such as Inverse Distance Weighting (IDW) and kriging, are commonly used in various fields. In Kriging method, semivariogram fitting is an important step, where empirical data are used to derive a theoretical model. However, when the known theoretical semivariogram model does not provide a satisfactory fit, the bias in the estimated values is increased. To address this limitation, Support Vector Regression (SVR) can be used to model the empirical semivariogram with a machine-learning method. This method has been applied in ordinary kriging interpolation for semivariogram fitting to estimate parameters related to the potential occurrence of earthquake. Specifically, the calculated parameters, based on the Gutenberg-Richter law, include the seismic activity (a-value) and rock fragility (b-value) in the Sumatera region. The results showed that SVR can model the empirical semivariogram better than the theoretical. The integration of SVR-Ordinary Kriging provides the best performance compared to other methods, such as IDW, with the smallest RMSEP values for both the b-value and a-value measuring 0.1378 and 0.7423, respectively. Aceh and Mentawai Islands tend to show low a and b values, suggesting that these areas are more vulnerable to earthquake with large magnitudes.

Abstract

Geothermal exploration activities involve a high degree of uncertainty and financial risk, thereby requiring exploration analyses that can support accurate decision-making. This study presents a geothermal exploration method for determining the Geothermal Potential Index (GPI) by integrating surface geological, geophysical, and geochemical data.  The main problem addressed in this study is the testing of a method for conducting geothermal exploration by integrating multiple parameters. Accordingly, this research applies a knowledge-driven approach through the Analytic Hierarchy Process (AHP) to develop a tentative Geothermal Potential Index (GPI) model. The Analytical Hierarchy Process (AHP) serves as a reliable methodological framework for assessing the Geothermal Potential Index by integrating newly obtained and pre-existing data. By incorporating suitability analysis, identifying prospective resources, and formulating geothermal resource criteria, this approach establishes a solid basis for systematic evaluation during the geothermal exploration phase. The tentative model of the geothermal potential index (GPI) for the Dieng volcanic complex has been identified into five zones: Pagerkandang Zone, Siglagah Zone, Pangonan-Merdada Zone, Campursari Zone, and Pakuwaja Zone.

Abstract

A paradigm shift in disaster risk reduction and management is evident, with social media and crowdfunding playing an important role, even in disaster-prone developing countries like India, with a pronounced digital divide. With the advent of social media platforms coupled with the frequent landfalls of cyclones in the Indian Sundarbans, a climate hotspot has become a classic example of this trio - social media, crowdfunding, and disaster tourism. The main objectives are to bring out the essence of changing the relief donation scenario from traditional donation to modern digital crowdfunding, to assess how far technology and social media, more specifically, have been able to help the eager contributors to take part in the cause of disaster management through hypothesis testing, regression analysis, SWOT analysis, focus group discussions, and perception studies. The empirical research (carried out between 2022-23) based on a semi-structured questionnaire survey involved the stakeholders –donors and beneficiaries. The study notes the nature of social media platform usage, identifies the main driving forces behind opting for specific donation drives, and delves into the underlying reasons for undertaking disaster tourism trips. The study shows that increased use of social media has led to greater acceptance of online crowdfunding initiatives, especially among the younger and educated.

Abstract

The readymade garment factory fires have become major concern in the industrial sector of Bangladesh by placing tremendous pressure on the nation's impoverished garment workers. The garment workers are suffering from fatalities, serious injuries, and loss of livelihood. This study's main objective is to examine how Bangladesh's garment industry is vulnerable to fire risks from 2000 to 2024. The majority of the data and information used in this study were collected from secondary sources, including governmental documents and non-governmental organizations. Since the garment business first emerged in Bangladesh, it has faced several difficulties, including fire, which has significant national and international implications. Most factories are situated in close proximity to one another in fire-prone districts, and factory authorities often neglect to take necessary safety precautions. A series of fire accidents occurred in the country over the period and often captured international headlines. Therefore, it is very important to adopt effective measures, such as implementing realistic safety strategies, emphasizing mitigation, ensuring basic safety equipment in factories, providing training to factory staff, and upholding international standards to prevent fires in factories.

Abstract

This study examines the integration of STEM technologies into geography programs in higher education institutions to develop students' research competencies, spatial thinking, and interdisciplinary problem-solving skills. Based on a systematic analysis of 29 recent publications on STEM in geography education, the study identifies five key features of STEM-based learning: organizing research activities, developing practical and analytical skills, encouraging innovative and project-based thinking, effectively using digital tools and GIS, and gradually introducing STEM methodologies. Drawing on the international experience of countries such as Malaysia, China, and Indonesia, a STEM laboratory model for teaching geography is proposed. The results show that the structured implementation of STEM technologies significantly improves students' ability to conduct experiments, analyze data, make predictions, and develop critical thinking, thereby preparing future specialists to solve social, environmental, and economic problems. This study lays the foundation for integrating STEM into geography curricula and offers practical recommendations for creating a laboratory learning environment in universities. In general, geography, using STEM technology, can study or analyze issues such as urbanization, socioeconomic inequality, disease incidence (mapping), migration, natural.

Abstract

In the context of digitalization, there are many obstacles to the successful introduction of geospatial technologies (GST) into school geography and their integration with geographical education. The main one is the low geospatial education of teachers. The purpose of this study is to develop a curriculum for advanced training courses and an experimental study of its effectiveness by analyzing the content of the school's geography educational programs and studying the demands of geography teachers for geospatial knowledge. During the study, such general scientific methods as review, analysis, synthesis of scientific papers, study, comparison of regulatory documents on education were used. Based on the analysis of the role of GST in the curricula of Kazakhstan's secondary education and a survey study of the professional needs of geography teachers in geospatial education, 2-level (basic, advanced) training programs of advanced training courses for geography teachers, an additional manual for it, have been developed. The effectiveness of the basic level curriculum has been proven by an experimental study. The results of "pretest" and "posttest" from 24 teachers participating in the experiment showed that after the refresher course, the spatial skills of the course participants increase from "insufficient" and "average" to "high" and "very high". The research carried out supports the introduction of GST in school geography and contributes to speeding up this process.Received: 2025-02-20 Revised: 2025-08-04 Accepted: 2025-12-03  Published: 2025-12-31

Abstract

The availability of groundwater for irrigation in Purbalingga Regency, requires significant attention since the region has an extensive rice field, necessitating systematic groundwater exploration and the implementation of appropriate management strategies. A geoelectrical resistivity survey has been conducted to investigate groundwater resources and to construct a hydrostratigraphic model that facilitates the interpretation of hydrogeological conditions, including aquifer distribution, groundwater depth, and productive zones. Resistivity data were collected from 16 points distributed across the districts of Kalimanah, Purbalingga, Kemangkon, and Bukateja. The correlation of resistivity logs produced detailed hydrostratigraphic cross-sections, illustrating lithological variations, layer thicknesses, and aquifer distribution. Interpretation down to a depth of 200 m identified two major formations: the Alluvium Formation and the Terrace Formation. The Alluvium Formation, consisting of sandy clay, sand, and clayey sand, exhibits resistivity values ranging from 0.87 to 69.43 Ωm, whereas the Terrace Formation, composed of tuffaceous sandstone, sand, conglomerate, and tuff, with resistivity values between 7.81 and 38.09 Ωm. Hydrostratigraphic modeling indicates that aquifer productivity varies across the study area. Kalimanah District, dominated by low-resistivity deposits (0.87–8.55 Ωm), is interpreted as having the highest aquifer productivity, making it particularly suitable for the development of groundwater-based irrigation. This study introduces a resistivity-based interpretative approach to classify hydrostratigraphic characteristics by correlating resistivity values with local geological conditions.

Abstract

The Gunungsewu Karst is a landscape that is highly vulnerable to degradation. Infiltration rate is a critical factor in efforts to protect and conserve karst environments, however, studies focusing specifically on infiltration processes at the valley floor of karst systems, particularly in relation to the morphological characteristics of the Gunungsewu karst, remain limited. This study aims to examine the characteristics of soil infiltration rates at the bottom of the Gunungsewu karst valleys based on their morphological units. Field measurements of infiltration rates were conducted using a double-ring infiltrometer, and infiltration parameters were calculated using the Horton model. Sampling was carried out according to the morphological classification of the Gunungsewu Karst, which includes rounded karst cone units (K1), elongated karst cone units (K2), and trapezoidal karst cone units (K3). Data analysis employed a descriptive approach based on data distribution, visualized using box-and-whisker plots and line graphs.The results indicate distinct differences in infiltration rate characteristics among the morphological units. Infiltration rates across all sites ranged from 0.10 cm min⁻¹ to 0.65 cm min⁻¹. The highest infiltration rates were observed sequentially in the K1, K2, and K3 units. Variations in infiltration rate characteristics within the study area are strongly influenced by morphological features, lithology, vegetation cover, and land use. These findings enhance the understanding of infiltration rate characteristics in karst environments and provide a scientific basis for the development of sustainable strategies for karst environmental protection and conservation.Received: 2025-04-10  Revised: 2025-10-10  Accepted: 2025-12-16 Published: 2025-12-31
