Geo-spatial Assessment of Flood Vulnerability Areas of the Gaza Strip Towards Preparedness and Humanitarian Response Planning

Abstract

Nowadays, flood and drought will become more common as climate change causes. Due to climate change consequences, flood occurrence and its impact on Gaza people have been of great concern to the Palestinian water authority, as it has a negative influence on various humanitarian and social issues. The hazards and damages resulted by flooding cause loss of life, property, displacement of people and disruption of socioeconomic activities. This research focuses on assessing Gaza Strip vulnerability to flooding using analysis of GIS-based spatial information. Not only did it consider the physical-environmental flood vulnerability, it also investigated social flood vulnerability aspects e.g., population densities. Soil and slope were considered to have the highest weight in the vulnerability mapping, as they represent the main factors in urban hydro-ecosystem structure. The long term average rainfall, a climate function factor, has the lowest weight, because it could be considered as a threat factor in addition to a vulnerability factor. This research demonstrates that urban area and population density as strong factors influencing flood vulnerability for humanitarian and saving life purposes. The findings of Geospatial analysis were used to map vulnerable areas likely to be affected in the event of flood hazard and suggest future interventions and related adaptation strategies in Gaza areas for flood mitigation.

Clean energy transition and climate vulnerabilities: A comparative analysis of European and non-European developed countries

“…In particular, ecosystem vulnerability refers to the sensitivity and resilience of ecosystems to external disturbances. This vulnerability has become widespread worldwide [13]. Further, ecosystem vulnerability and renewable energy assessment [1] results indicate that energy cleanability is an encouraging and significant factor in reducing climate change.…”

Micro‐spatial flood risk assessment in Nagaon district, Assam (India) using GIS‐based multi‐criteria decision analysis (MCDA) and analytical hierarchy process (AHP)

“…Noteworthy that, taking either physical or socioeconomic vulnerability indicators may not give a clear picture of the flood risk areas. Hence, an area that is highly vulnerable to floods in terms of the physical aspect may not have a higher degree of vulnerability under the concerned socioeconomic environment (Eshtawi et al., 2021). The present research, therefore, demonstrates several hazard (rainfall, slope, elevation, geomorphology, topographic wetness index [TWI], etc.)…”
