Resilience and Vulnerability: The Haouz Earthquake's Effect on Housing In The Western High Atlas of Morocco

Hamza Ait Zamzami — 2024-03-28

This article delves into the vulnerability of traditional dwellings and cluster housing in the Western High Atlas region of Morocco, highlighting the major challenges they face during earthquakes. These houses, often built with natural materials such as earth, stone and wood, reveal structural limitations in the face of nature's relentless forces. More specifically, the article looks at the devastating Al Haouz earthquake of 2023, which marked the region's history as the most powerful earthquake in over a century. It left behind a tragic legacy of loss of life and considerable material damage. This underlines the imperative of understanding the seismic risks to which these traditional dwellings are exposed, particularly in a culturally and geologically rich and tectonically active region. The article goes beyond simply identifying the problems, highlighting the considerable efforts made by the government and civil society to rebuild and prepare the region for similar disasters in the future. It also highlights the need to strengthen the resilience of these traditional dwellings and to reconsider building standards to better cope with seismic risks.

Analysis of The Influence of Environmental Behavior on The Water Balance of Kaligarang Watershed, Central Java

Rohman Hakim — 2024-04-02

The increasing population and land needs have led to changes in people's behavior towards the watershed, resulting in indications of disruption of the water balance. Therefore, it is necessary to investigate how community behavior affects the water balance of the Kaligarang watershed. This research is a combination of quantitative and qualitative approaches. The method of withdrawing respondents was purposive sampling. Data collection was done through observation, documentation, questionnaire distribution to respondents and interviews with key persons. Calculation of water balance using the Thorntwaite-Mather method. The results of the water balance calculation show that in periods 1 and 2 there was a surplus from December to April and a deficit from May to November. Deficits tend to increase while surpluses tend to decrease. From period 1 to period 2 the deficit increased by 142 mm and the surplus decreased by 316 mm. The tabulation results show that there are community behaviors that have a negative influence on water balance. This is reinforced by the results of interviews with key figures (key person) stating that environmental behavior has a negative influence on water balance.

Analysis of Landslide Susceptibility in Klaten Regency

Oryza Febriana — 2024-03-28

Landslide disasters are frequently occurring events in Indonesia. The northern part of Klaten Regency, situated on the slopes of Mount Merapi, and the southern part, which directly borders limestone hills, are vulnerable to landslides due to their elevated terrain. This research aims to investigate the role of Geographic Information Systems (GIS) in analyzing, mapping, and identifying areas prone to landslide disasters. Mapping landslide susceptibility as a GIS application aims to be a disaster mitigation effort, thereby minimizing the resulting impacts and losses. The mapping is conducted based on the Puslattinak method, using several parameters such as rainfall, slope, rock types, land use, and soil types. This mapping employs a weighted multi-level analysis method, where each parameter has a different weight depending on its influence on landslide disasters. The results of this research include the Landslide Susceptibility Map of Klaten Regency in 2022. According to the research findings, Klaten Regency is divided into three susceptibility classes: low (17,868.23 hectares), medium (41,494.22 hectares), and high (10,533.96 hectares), with rainfall intensity being the most influential parameter

Pattern of Sprawl Development Along The Abuja – Keffi Highway Corridor in The North Central Nigeria

Sabo Jibrin — 2024-03-28

The rapid expansion of urban areas worldwide is widely attributed to the growth of urban populations. The objective of this study is to examine the expansion of urban sprawl in the North Central area of Nigeria, specifically along the Abuja-Keffi highway corridor, over 29 years, from 1991 to 2020. The study utilized satellite imagery from three distinct spatiotemporal intervals (1991–2003, 2003–2015, and 2015–2020) and incorporated three different types of Landsat sensors, namely Enhanced Thematic Mapper (ETM), Enhanced Thematic Mapper Plus (ETM+), and Operational Land Imager (OLI). The study employed image processing and land use classification analysis techniques to generate land use and land cover (LULC). The analysis of the data reveals that there has been a significant increase in sprawling development along the Abuja-Keffi highway corridor. The built-up area of the region has undergone significant expansion over the past three decades, with the urbanized land area increasing from 1081.98 hectares (4.96%) in 1991 to 10263.15 hectares in 2020, accounting for 47.06% of the total built-up area. The research also documented two distinct forms of urban growth, specifically linear and leapfrog, throughout the corridor. The research recommends regional urban policy, urban growth boundaries as well as effective and efficient development control mechanisms in the selected settlements along the corridor. The Abuja Municipal Area Council and Karu Local Government are urged to promote urban renewal and infrastructure development through private partnerships, sustainable policies, waste management systems, and community engagement.

Spatio Temporal Analysis of Urban Heat Island Using Landsat 8 Oli/Tirs Imagery in Klaten District In 2013 – 2021

Hendra Wahyudi — 2024-03-28

Klaten Regency is one of the areas that has experienced changes in use over time, such as agricultural land becoming built-up or non-agricultural land. This has an impact on the increase in air temperature which can lead to the occurrence of the phenomenon of the Heat Island or Urban Heat Island. This study aims to determine the spatio-temporal variation of vegetation index value (NDVI), Surface Temperature and in Klaten Regency in 2013 - 2021 and determine the relationship between vegetation index value (NDVI) and UHI in Klaten Regency. The method used in this research is Landsat 8 image data processing such as NDVI, LST and UHI calculation to get the final result. Meanwhile, to get the relationship between NDVI and Surface Temperature related to the UHI phenomenon, simple regression testing was carried out. The results obtained from the processing results show that Klaten Regency is dominated by vegetation cover density with very high and high classifications despite the decrease in area from 2013 to 2021. Surface temperature in Klaten Regency is dominated by surface temperatures within the range of 25 - 28o C spread across the entire region from 2013 to 2021. The results of the linear regression have a coefficient value of r2 where the value shows results with a value of 0.377. The result of the coefficient of determination shows that the amount of influence obtained from the density of vegetation land cover with an average surface temperature of 37.7% where the rest can be influenced by other factors.
