The effects of anthropogenic induced geomorphological changes on mangrove forests in Tarut bay, on the East coast of Saudi Arabia

Abstract EN

Anthropogenic induced geomorphological changes are considered one of the most significant changes in the natural environment.

human are an active geomorphological factor, as his role is greater than other factors in modifying the landform, these human interventions have a significant impact on mangrove communities around the world.

the current study aims at reveal the effects of anthropogenic induced geomorphological changes on the mangrove forests in Tarut bay.

the problem of the study was crystallized in the light of field observations of the deterioration of mangrove forests in the study area, as well as in the widespread human activity in the coastal region, which is represented in the extensive filling of shallow waters with the aim of urban development to keep pace with the increasing demand for housing, commercial investment and tourism.

the study was conducted by remote sensing techniques and making comparisons between satellite images in different years to determine the magnitude of changes, whether in Tarut bay or Tarut island, and the impact of these conditions on mangrove communities during the period from 1986-2021.

the study came to a number of results, the most important of which are, the area was subjected to major geomorphological changes that greatly affected the mangrove sites, which resulted during 35 years in a decrease in the mangrove area from 13.11 km 2 to 4.5 km 2, where some sites were completely degraded as a result of the continuous cutting of mangrove trees, as is the case in the southern coast of Tarut island and the southwest coast of bay of Tarut.
