Abstract

The purpose of this study was to  create an erosion prediction model in Serang Watershed, Indonesia. The erosion model used two input data, namely the slope derivied from Digital Elevation Model (DEM) data, and Fractional Vegetation Cover (FVC) from SPOT images. Assessment of the model was carried out using questionnaires and interviews with several experts by presenting the results of the model and its supporting data. Based on the DEM data, the level of slope steepness in the study area is very varied namely; flat (52.77%), sloping (7.62%), and rather steep to very steep (39.59%). Vegetation density according to the FVC results is dominated by medium density. The results of the analysis of the two input models can provide predictions of the level of erosion with an accuracy of 67.92%. Evaluation of the model was done by experts with conclusions that the method was very flexible and can be adapted to similar watersheds elsewhere.

Abstract

This study aimed to evaluate the environmental and socio-economic impact of traditional brick-making in Goma Division. The research methods included semi-structured questionnaires, key informant interviews, field observation, and focused group discussions. The results indicated that traditional brick-making is causing harm to the biophysical environment in the form of the degradation of wetland vegetation and deforestation (100%), landscape deformation (85%), air and water pollution, whereby DO had reduced by 19.8%, BOD, pH, TSS, TDS, EC and turbidity had increased by 3.8±0.9 ppm, 1.2±0.1, 89.4±0.1 mg/L, 18±0.9 ppm, 70±0.7 µS/cm, and 264±44 NTUs, respectively. Water pollution loads varied from point to point of sampling significantly at p<0.05, with the highest loads found at the tail end or downstream of the site but lowest at a point upstream of the clay mining site. The socio-economic analysis showed that the benefits of brick-making outweigh the costs in terms of magnitude, except for the frequency of responses. All respondents indicated that brick-making had created employment, while 87% reported an improvement in their standard of living. However, the activity is associated with accidents that can result in loss of life or bodily injury. It was concluded that Mukono Municipal Environmental Officers should monitor brick-making mines and site activities to prevent the creation of open pits and caves. The environment should be treated as a borrowed asset to ensure sustainability. The study suggests that financial support and awareness should be available to clay miners and brickmakers to ensure sustainability.

Abstract

Agrarian conflicts in Uganda are deeply embedded in the nation's historical, social, and economic contexts. Rooted in colonial-era land policies, such as the Mailo land system, these conflicts continue to shape land ownership and agricultural practices, contributing to socio-economic inequalities. This paper examines the causes and consequences of agrarian disputes in Uganda, focusing on land tenure disputes, ethnic and regional conflicts, government policies, population pressures, and the commercialization of agriculture. The study finds that historical land tenure systems, particularly the Mailo system, have created lasting inequalities, while modern governmental policies and population growth exacerbate land-related conflicts. Additionally, the shift towards large-scale commercial agriculture has marginalized smallholder farmers, contributing to social instability. Addressing Uganda’s agrarian conflicts requires a comprehensive and inclusive approach to land reform, incorporating stronger governance, sustainable land management, and respect for indigenous rights.

Abstract

This study examined the relationship between climate variability adaptation strategies and household food security. Specifically, it investigated the adaptation practices employed by farmers and assessed their impact on food availability by comparing food security outcomes between adapting and non-adapting households. Data were collected from 375 randomly selected households in Agoro and Madi Opei sub-counties, known for their transitional climatic conditions. Employing questionnaires, field observations, and key informant interviews, the study found early planting (38.2%), new crop varieties (25.4%), drought-resistant crops (21.6%), and small-scale irrigation (7.8%) to be the primary on-farm adaptations, while motorcycling (50%), retail (25%), and construction-related activities (10%) dominated off-farm strategies. In the surveyed households, 1.2% experienced inadequate food availability, 95.7% exhibited moderate food security, and 3.1% demonstrated adequate food security. The study revealed a positive correlation between adaptation practices and food security, suggesting that various adaptation strategies can enhance household resilience to climate variability.

Abstract

The Semliki River valley in Ntoroko district has experienced devastating annual floods since 2019. Recurrent floods in Ntoroko District have displaced thousands and devastated pasturelands, disrupting livelihoods. Therefore, rapid assessment of flooded areas is crucial for developing effective mitigation strategies, disaster preparedness plans, and proactive policies to enhance resilience and mitigate the impact of future flood events.  This study introduced a combined approach using Synthetic Aperture Radar (SAR) imagery and a digital elevation model (DEM) to map flood extent, depth, and building exposure in the Semliki Valley. Using Sentinel-1 SAR images taken both before and during the flood, combined with the ALOS PALSAR DEM, inundated areas and flood depths were determined, based on thresholding the SAR backscatter of the VH polarisation images. The flood extent maps were generated using Google Earth Engine and GIS techniques to create depth maps by subtracting the surface elevation from the height/surface of the flood waters. Building exposure and impact analysis for two flood events was ascertained through spatial join and overlay. The results showed that the 2023 flood event inundated approximately 1,968 hectares, including 1,553 hectares of pastureland and 74 buildings, while the 2024 event covered 1,139 hectares, equally inundating 1,050 hectares of pastureland and 54 buildings. Further analysis revealed that despite the smaller extent, the 2024 flood event caused a severe impact on the buildings compared to the 2023 flood disaster.

Abstract

Indonesia, as an archipelagic nation with an extensive coastline, influences the resource potential in coastal regions, including fisheries, the fishing industry, ports, and tourism. This potential renders coastal regions a dynamic interface between land and sea. Coastal communities should consistently endorse the available potential due to their expertise, competencies, and community advancement. The improper use of natural resources and the coastal environment can lead to numerous issues and result in the depletion of potential resources. Community development in the management of coastal and marine resources can be enhanced to support tourism activities, including the provision of local souvenirs and tourist services. This study aimed to assess the potential of capture fisheries and coastal environmental resources to facilitate the development of new tourist destinations in Pacitan Regency. The qualitative research employed methods of field observation and documentation. The findings indicated that capture fisheries in 2023 generally experienced an increase, whereas the decline was attributed to climatic conditions in the southern sea, which occasionally prevented fishermen from venturing out to sea. Fisheries serve not only community requirements but also facilitate fish processing to enhance tourism activities, transforming fish into souvenirs for coastal tourism. The construction of the JLS road facilitates the development of coastal tourism destinations, although certain areas remain challenging to access from the main road. Surfing sports tourism is a prominent destination, predominantly attracting international tourists. A classification of hugging beaches offers developmental prospects for ports and diverse marine tourism in Pacitan Regency.

Abstract

Indonesia is a disaster-prone country, especially in terms of geological disasters. Applying disaster education through simulation methods is expected to give the community the right knowledge and attitude toward disaster response. This study aimed to determine and analyze the knowledge and attitudes of students in higher education in responding to geological disasters through simulation learning methods. The population in this study was students of the Social Sciences Education Study Program from five Islamic universities in East Java, Indonesia, and the sample was 378 students. The method used was quantitative with univariate and bivariate data analysis. The study results from the analysis stated a significant difference between the knowledge and preparedness of geological disasters in students in the control group and the experimental group, with a P value of 0.0001. Thus, the knowledge and disaster preparedness level in students who received simulation learning was higher than in students who did not receive learning with the simulation learning model. This study implies that the simulation learning model can be used as a reference in implementing disaster education, especially in disaster-prone areas.

Abstract

The Paguyaman Watershed represents a strategically significant and essential water resource for the surrounding region. In recent years, this area has become increasingly vulnerable to environmental pressures, including heightened sedimentation, changes in land use, declining water quality, and more frequent flooding events. This study aims to evaluate the morphometric characteristics of the Paguyaman Watershed and their relationship to flood vulnerability observed over the past five years. Morphometric analysis was conducted using quantitative methods within GIS and remote sensing approach. The primary dataset utilized was DEMNAS. The analyzed morphometric parameters include drainage density (3.95), stream frequency (8.61), bifurcation ratio (8.41), form factor (0.13), elongation ratio (0.40), and ruggedness number (8.20). These parameter values indicate that the Paguyaman Watershed possesses an elongated concave shape, steep topography, high surface runoff intensity, and low infiltration capacity. The findings reveal that the watershed exhibits characteristics of high flood susceptibility, as evidenced by recurrent flood events in the villages of Totopo, Tolite, and Juria over the last five years. The spatial pattern of flood vulnerability within the watershed is closely linked to morphological features, such as steep slopes, low soil infiltration capacity, and excessive surface flow accumulation—particularly within the Bilato and Boliyohuto sub-districts.
