Abstract

Pasuruan Regency, with 213,686 farmers and a population growth rate of 0.4–1% annually, faces an urgent need for a stable food supply due to fluctuating potato prices and stock levels linked to unplanned planting. This study aims to identify optimal potato planting patterns and schedules using the Thornthwaite-Mather water balance method, based on monthly rainfall data. The Oldeman climate classification revealed five climate types in Pasuruan: C2, D2, D3, D4, and E, influenced by monsoon patterns affecting soil water availability. Soil moisture levels are suitable for potato planting from January to March, decrease from May to October, and increase again in November. The western region (Pasuruan city) tends to be drier, with a longer dry season. The resulting planting schedule recommendations are as follows: climate type C2 (first planting season: November–February; second planting season: March–June), D2 (first planting season: December–March), D3 (first planting season: January–April), and D4 and E (first planting season: February–May), to support the stability of potato production and food security in Pasuruan on a sustainable basis.

Abstract

Oil spills represent a major form of marine pollution that poses serious threats to coastal ecosystems and human activities. This study aims to detect and analyse the spatial distribution of the oil spill in Lhokseumawe waters using Sentinel-1A Synthetic Aperture Radar (SAR) imagery with software SNAP. The dataset used consists of Sentinel-1A SAR imagery acquired on 24 April 2022 with Interferometric Wide Swath mode and VV polarisation. Oil spill detection was performed using an adaptive thresholding approach through the Oil Spill Detection Tool. The oil spill was identified as a dark area with low backscatter values forming elongated and fragmented patterns influenced by ocean currents and wind conditions. Variations in the threshold shift values produced different estimated extents of the oil spill, namely 36.86 km² at the 1.0 dB threshold, 12.82 km² at the 2.0 dB threshold, and 4.61 km² at the 3.0 dB threshold. Although potential false detections may occur due to look-alike phenomena, this study demonstrates that Sentinel-1A SAR imagery is effective for monitoring oil spills in coastal waters.

Abstract

Expansion of anthroposphere activities in the Wonosalam River watershed, Jombang, triggers ecological pressure in the form of organic pollution. This study analyzes environmental quality degradation through an environmental approach based on macroinvertebrate biomonitoring using Biotilik and Family Biotic Index across stations 1, 2, and 3. Results show aquatic geological findings that align linearly with land use intensity. The densely vegetated upstream segment serves as a refugia zone for sensitive organisms at 1.8 percent. Conversely, the midstream and downstream areas intersected by agriculture, livestock farming, and settlements experience massive degradation dominated by tolerant taxa Buccinidae and Thiaridae with a Biotilik Index of 1.83, indicating moderate pollution. Geologically, the biosphere dynamics of this river are driven by spatial connectivity between anthropogenic activities and declining environmental carrying capacity. Changes in land use and high levels of anthropogenic waste pressure are directly correlated with the degradation of riverine biological community structures. These research findings underscore the need to limit land-use conversion and implement watershed zoning management based on bioindicator monitoring to ensure the sustainability of aquatic ecosystems.

Abstract

Rapid urbanization in developing nations has intensified pressure on urban streets, forcing them to accommodate both pedestrian mobility and informal economic activity. This study examines how the interaction between informal trading and pedestrian flow shapes the character of urban space in Bukoba, Tanzania. Data were gathered through observation, structured interviews, mapping, photographic documentation, and document reviews, and analyzed using qualitative descriptive and simple quantitative methods. Walking remains the primary mode of daily transport despite inadequate infrastructure, mixed traffic, and encroachment by street vendors. Concurrently, informal traders cluster in high-foot-traffic areas to sustain their low-income livelihoods. Although these trading activities often disrupt pedestrian continuity and convenience, they also foster urban vitality and facilitate access to daily services. The study concludes that the relationship between street walking and informal trading is both complementary and conflicting, highlighting the need for context-responsive urban planning and design that enhances walkability while preserving the vital socio-economic role of the informal sector.

Abstract

Soapstone quarrying has been a continuous activity that has altered the natural landscape, in turn affecting agricultural land. In Tabaka Ward, Kisii County, Kenya, the expansion of quarrying activities has led to significant changes in agricultural land-use patterns. This study examined the effects of soapstone quarrying on agricultural land, aiming to determine the extent to which quarrying activities have transformed productive agricultural land. The study combined qualitative and quantitative data gathered from field observations, household surveys, key informant interviews, and photographs. A proportionate stratified random sampling technique was used to select 382 household respondents, while purposive sampling was employed to engage 12 key informants. Quantitative data were analyzed using descriptive statistics and a paired-sample t-test. The results showed that while the average farm size was 2.8 acres, an average of 0.5 acres per farm had been converted to soapstone quarrying. Findings further revealed a 23.8% decline in crop production, severe loss of topsoil, reduction of pasture fields, and an overall loss of arable agricultural land. The paired sample t-test confirmed a statistically significant difference between total farm size and the land allocated to quarrying (t(381) = 12.884, p < 0.001). The study concluded that soapstone quarrying has radically altered agricultural land use, diminished grazing fields, and lowered overall agricultural productivity.

Abstract

Hydrometeorological flood disasters in West Java Province demonstrate dynamic spatiotemporal fluctuations. However, the macro-static hazard modeling currently in common use frequently triggers spatial mismatch with actual field conditions. This study examines the flood hazard levels in West Java Province during the 2021–2025 period by integrating historical flood event data with regional flood hazard index raster maps. The dataset consists of annual flood event points from the Regional Disaster Management Agency (BPBD) of West Java Province and flood hazard rasters, which were analyzed using Geographic Information System (GIS) software via the Sampled Raster Values technique. All data were first standardized by unifying coordinate systems, geometry types, and attribute structures to enable simultaneous layer analysis. Spatial analysis was subsequently conducted to assess the alignment between actual flood occurrence locations and designated flood hazard classes. The results indicate that flood events over the five-year observation period occurred predominantly in low-hazard zones (34%–42%), whereas high-hazard zones accounted for a relatively small proportion (less than 15%). Furthermore, Null values were identified, signaling spatial mismatch between actual flood points and raster cells within the hazard model across all years. Consequently, this study underscores the urgent need for dynamic reconstruction and spatial resolution updates of hazard models by relevant authorities to maintain the integrity of disaster management databases in the future.

Abstract

Rapid densification in Jakarta has increased pressure on basic urban services and raised concerns about whether high-density neighborhoods enjoy adequate walking access to health, economic, and transport services in Mampang Prapatan District. This study aims to assess this accessibility by combining open building footprints, a simple population estimation method, and network-based accessibility analysis. Building footprints from Google Open Buildings were used to approximate the number of residents per 500 × 500 m grid cell, assuming an average of four inhabitants per residential building. Points of interest for health facilities, small-scale economic activities, and public transport stops were collected from Google Maps, and walking times along the OpenStreetMap street network were calculated using a closest-facility analysis. Each grid cell was classified into one of five accessibility classes—Very Low, Low, Moderate, High, and Very High, and a composite accessibility index was constructed to summarize combined access to all three service types. The results show that most high-density grid cells in the central and north-eastern parts of the district fall into the Moderate, High, or Very High classes, together accounting for 69% of the study area and indicating relatively compact and walkable access to key services. In contrast, 31% of grid cells, concentrated in the southern and south-western areas, remain in the Low or Very Low classes, revealing clear spatial inequalities in access to pedestrian links. The approach is straightforward to implement with open data and can support local planning efforts aimed at promoting more equitable, walkable, and low-carbon urban development.

Abstract

Agricultural investments and support technologies play a vital role in improving agricultural productivity, profitability, and sustainability by allocating financial, physical, and human resources to farming activities. This study investigated how agricultural investments and the use of support technologies enhance household food sufficiency among smallholder farmers, with particular emphasis on the role of institutional factors. A descriptive research design was employed to collect quantitative and qualitative data from a sample of 398 respondents in Tharaka Nithi County, Kenya. Quantitative data were gathered using structured questionnaires administered to farming households, while qualitative data were obtained through key informant interviews with agricultural officers, cooperative leaders, and other relevant stakeholders. The study revealed that institutional factors significantly influenced both agricultural investments and the adoption of support technologies. High input costs were identified as the primary constraint to agricultural investment (M = 4.20), while corruption (M = 4.13) and political interference (M = 4.07) further hindered investment decisions and technology uptake. Conversely, key institutional drivers including market access, farmer organizations, research collaboration, subsidies, credit availability, extension services, cooperatives, and farmer training were perceived as essential enablers, with mean scores ranging from 3.80 to 3.98 on the Likert scale. Based on these findings, the study recommends that national and county governments strengthen institutional support by expanding access to affordable inputs and credit, enhancing extension services, promoting transparency in subsidy programs, and strengthening farmer cooperatives, research partnerships, and market linkages to improve household food sufficiency.

Abstract

Fieldwork remains a fundamental component of geography education, enabling students to connect theoretical knowledge with real-world landscapes, environmental processes, and community contexts through experiential and enquiry-based learning. However, contemporary higher education faces several challenges in sustaining effective field-based learning, including limited institutional support, financial constraints, safety concerns, unequal participation, gender-based barriers, and disparities in access to technology. Despite its recognized pedagogical significance, empirical understanding of how these challenges influence geography fieldwork in the Indian higher education context, particularly in Kerala, remains limited. This study aims to critically examine current fieldwork practices in higher education institutions in Kerala and explore pathways for developing an experiential, inclusive, and technology-enhanced model of geography field education. The study employed a qualitative-dominant mixed-methods research design involving six higher education institutions affiliated with the University of Calicut, University of Kerala, and Kannur University during the academic year 2024 to 2025. Data were collected from 170 participants, including faculty members, students, curriculum planners, and technical staff, through surveys, interviews, focus group discussions, participant observations, and document analysis. Quantitative data were analyzed using descriptive statistics, while qualitative data were examined through thematic analysis using NVivo 12. The findings demonstrate that fieldwork significantly improves students’ geographical understanding, with statistically significant gains observed in pre- and post-fieldwork assessments. However, the study identified institutional disparities in funding, GIS infrastructure, faculty training, and digital resources. Technology adoption remained uneven, and female students faced notable safety, mobility, and accessibility concerns. The study recommends curriculum integration, institutional investment, capacity-building, equitable technology access, gender-sensitive protocols, and interdisciplinary collaboration to strengthen fieldwork practices.
