Abstract

Some geography education students score poorly in wetlands ecological literacy. This study aimed to determine the effect of outdoor learning on wetlands ecological literacy using a pre-experimental design and a sample of 60 geography students. The wetlands ecological literacy instruments were adapted from Anderson's cognitive dimensions comprising factual, conceptual, strategic, and metacognitive indicators. Data were analyzed using percentages and non-parametric Wilcoxon ranked statistical sign tests. The result showed that 2-tailed Asymp. Sig. was 0.000, smaller than 0.05. The conceptual and metacognitive indicators had the highest and lowest improvement of 21.11% and 13.33%, respectively. Furthermore, students’ wetlands ecological literacy improved through outdoor learning. Outdoor learning increases students’ attention to their environment through closer interactions, complementing the learning experience. Therefore, outdoor learning improves students’ wetland ecological literacy.

Abstract

Pamekasan coastal area is the center of salt production concentrated in the Pademawu subdistrict with the ponds area of 740.96 ha. The sufficiently close distance of salt ponds to settlement areas allows several issues, such as shallow groundwater salinization. This study aimed to determine the salt pond’s degradation over five years (2015-2020) and its influence on the salinization issue in Pademawu. We compare groundwater quality parameters (conductivity, TDS, the depth of shallow surface groundwater, and salinity) surveyed in 2015 and 2020, correlated to salt pond area alterations. Over five years of measurement, it was found that conductivity declined, reaching 2779.94 µS/cm. Based on TDS deterioration, groundwater transformed from brackish to freshwater in 2020. By contrast, the depth of shallow groundwater-surface increased by almost one meter. The freshwater area also increased by 22% over five years based on conductivity classification. Groundwater quality dynamics are related to the alteration of the salt pond area. On the other hand, the significant increase in rainfall intensity, which is not beneficial for salt agriculture, results in the salt pond area deterioration, thereby declining surface groundwater salinity in Pademawu due to the less interaction between Cl and groundwater within aquifers. Although the groundwater pollution induced by seawater intrusion and salinization declined in 2020, re-organizing the distance between salt ponds and the settlement area in Pademawu is crucial to minimize further groundwater pollution.

Abstract

This study aims to determine the impact of the geographical conditions of an area on the phenomenon of sirri marriage through a qualitative study. Data analysis was carried out inductively from the results of observations, in-depth interviews and FGDs. The results of the study indicate that the phenomenon of unregistered marriage occurs in Sumber Malang, Situbondo, East Java as a result of the geographical conditions of the area. The topographical conditions of the area in the form of mountainous areas with an altitude of 500-1,250 meters above sea level, very steep with a slope of 45%, rocky and dry soils make the Sumber Malang area difficult to develop economically. This is because agricultural cultivation is difficult to develop. Furthermore, the accessibility of areas that are difficult to reach because they are far inland, narrow roads, no public transportation, far from the center of economic activity have caused people in this area to choose to stay in their environment. Topography and regional accessibility have an impact on adolescent marriage behavior in the Sumber Malang community. Adolescents and parents view unregistered marriage as something that is done to avoid sin, the certainty of a relationship, economic motives (because the cost of marriage is considered expensive by the community) and as a result of the remote location of the area; because the teenager only has a circle of friends in Sumbermalang. There are two patterns of sirri marriage that occur, namely teenagers will marry sirri and live together and teenagers will marry sirri then stay with their parents and still continue their education. The implication of this research is to provide an illustration that geographical space can affect the pattern of marriage that occurs in society. Based on this, the relevant government can provide adequate access to education at the research sites.

Abstract

Large-scale climatic variability is seriously affecting rainfall and temperature distribution pattern in Sudano-Sahelian parts of Lake Chad Basin. The Kumadugu-gana and Yobe Rivers that drain the south-western part of the Lake Chad Basin now flow for six months only in a year instead of nine, and this has affected the entire ecosystem of the basin. This study examines the spatio-temporal variability of Kumagu-Yobe river basin rainfall. The study used monthly rainfall records for 1981-2017 from five different weather stations that spread across the up-and-downstream parts of the basin. To accomplish the objective of the study descriptive and inferential statistics were used in analyzing the rainfall attributes and temporal distribution pattern for each of the stations during the study period. Linear regression model was used in analyzing the stations rainfall temporal variability trend. The findings of the study revealed a large scale spatio-temporal variability in the distribution of the rainfall attributes during the study period. Generally, the basin recorded increasing trend of rainfall within the study period. Annual increasing trends of 1.1mm, 3.1mm, 17.6mm and 17.2mm were observed at Potiskum, Nguru, Bauchi and Kano stations respectively. Thus, Jos records insignificant decreasing trend of -0.2mm annually. Specifically, a variability of less than 1% was also observed at Jos and Potiskum stations which is statistically insignificant. A variability of 19%, 28% and 44% was observed at Nguru, Kano, Jos, and Bauchi respectively. Overall, throughout the study periods the basin recorded increasing trend of rainfall that is characterised with large scale fluctuations particularly at the upstream section of the basin. However, desertification and upstream water abstraction may have reduced any noticeable increase in stream downstream Keywords : River Yobe, Kumadugu-Yobe Basin, Rainfall, Spatio-Temporal variability Copyright (c) 2022 Geosfera Indonesia and Department of Geography Education, University of Jember This work is licensed under a Creative Commons Attribution-Share A like 4.0 International License

Abstract

The lack of rainfall-runoff accuracy is important for some applications. The choice of data aggregation that affects the estimation results is important at the level of accuracy. Some commonly used aggregations are daily, ten days, and monthly rainfall. This study aimed to compare the results of the estimation of the effect of data aggregation and to analyze the density of the rain gauge network in the Sampean watershed. The evaluation of the rain station network is carried out through the Kagan calculation. Rainfall data are from the rainfall data records for 20 years at 33 rain gauge stations. Measurement of the performance of aggregation variations using the relationship between the correlation value of rainfall with the distance between station locations. Station network positioning is assessed from alignment errors and interpolation errors. The results showed differences in the correlation and estimation values ​​in the variation of data aggregation.The greater interval can increase the effectiveness of deployment with minimum error. Based on Kagan's analysis, there is an uneven distribution of gauge stations in the Sampean watershed eventhough the average and interpolation error in the monthly rainfall is less than 5%. It is this inequality that causes gauge stations to be inefficient.

Abstract

Bangladesh is an agriculture based economic country formed by sediment deposition from upstream rivers. This riparian country covered with fertile soil that supports agricultural diversification. The study aimed to compare current soil quality of Jamuna-dhaleshwari (Manikganj) and Surma-kushiyara (Sylhet) floodplain physiographic regions to forecast about agricultural productivity. Soil quality was assessed through physical (soil texture and moisture), and chemical (pH, electrical conductivity (EC), salinity, soil nutrients (N, P, K), and organic matter content) indicators. A total of 36 soil samples in three different depths (0-15cm, 15-50cm, 50-100cm) from 12 sites were collected from Manikganj and Sylhet Districts. The average particle size and moisture content ratios of Manikganj: Sylhet were gravels (7.88:5.8), very coarse sand (6.85:8.53), coarse sand (7.45:13.2), medium sand (7.35:14), fine sand (6.12:16.4), very fine sand (24.3:19.9), silt (39.56:20.57), and clay (29.3:32.81), followed by, pH (7.61:6.31), and EC (0.24:0.18), respectively. The result revealed that the soil was bit alkaline for Manikganj, compared to range from alkaline to acidic in Sylhet and non-saline for both areas that was suitable for agriculture. The average concentration of nitrogen (N), phosphorous (P), potassium (K) nutrients in Manikganj and Sylhet Districts were 0.14%, 3.73 meq/100g, 0.07 µg/g; 0.16%, 3.11 meq/100g, 0.08 µg/g and organic matter were 3.65% and 4.7%, respectively. The results of nutrients in both areas indicated that nutrients were very poor but soil organic matter content was sufficient for agricultural activities. The study concluded that soil texture, pH, salinity and organic matter content in both areas were suitable for agricultural purposes, but a significant declined was found in soil moisture and nutrients quality. Finally, it was recommended that soils of Manikganj were more sustainable for agricultural activities.

Abstract

Local wisdom is the lives values ​that enables people to live in harmony with other individual and their environment. An example of a place that still maintains this value is a traditional village. West Java has eight Traditional Villages, one of which is the Pulo, located in Garut Regency, where the environment is still very well preserved because the values ​​of local wisdom are applied in environmental management. This study aims to analyzes the values ​​of local wisdom related to environmental management in Pulo Traditional Village community. Data were collected through observation, interviews, literature studies and documentation, then were analyzed descriptively using a qualitative ethnomethodology approach. The results showed that the community retains the value of local wisdom in maintaining their relationship with the environment by 1) preserving the prohibitions in the form of pamali, 2) prohibiting livestock rearing that pollutes the environment, 3) using certain plants wisely, as well as limiting the number of buildings and their occupants,and 4) constructing buildings with eco-friendly architecture. Therefore, these values need to be maintained to serve as a model or example for society in general.

Abstract

The Bahorok River basin has a high flash-flood hazard index. This is shown by loss of lives and damage of homes due to floods in recent years, however, no research examined community preparedness on the hazard of flash-flood. This research aimed to assess the effect of disaster experience and flood-risk perception on disaster preparedness of the people of Bukit Lawang Plantation Village. A cross-sectional survey design was used to determine the relationship between disaster experience, risk perception and preparedness as the independent and dependent variables, respectively. The results showed that disaster experience and risk perception positively and significantly affect the community preparedness. Disaster risk reduction programs in the region only focus on emergency response, rehabilitation, and reconstruction. Furthermore, increasing public awareness and preparedness has not been prioritized in reducing flood risk. This is an essential aspect for consideration because mountainous areas are often marginalized and lack access to disaster risk reduction programs.
