Quantitative soil erosion risk assessment due to rapid urbanization in the Cox’s Bazar district and Rohingya refugee camps in Bangladesh

Soil erosion due to anthropogenic interventions is an emerging threat the south-eastern coastal districts of Bangladesh. In recent decade, land degradation intensified this process in region settlement Forcibly Displaced Myanmar Nationals popularly known as ‘Rohingya’, who fled from 2017. To control soil erosion, it necessary identify locations and their intensity. The present study has attempted quantify regional loss (from 2015 2020) using Revised Universal Loss Equation model. method, risk assessments are carried out by integration different physiographic parameters spatial dimension. Results showed that year 2020 witnessed mean at a rate around 58.2 59 t ha− 1 yr− 1, respectively Cox’s Bazar district which 20–21% area was highly subjected erosion. But Rohingya camps for these periods 78 with cumulative increase 32%. sub-districts adjacent refugee (Ramu, Ukhia, Teknaf) have experienced intense compared others. From 2020, large about 4.54 (6%) observed Palongkhali union whereas maximum decrease − 8.08 (23%) Pokkhali union. camps, worst erosion-affected areas 8E, 10, 14, 15, 16, 17 having more than 100 loss. geographic detector method used influence factors on Land use change found be major contributing factor 2020. variations significantly controlled slope elevation factors. This work can help understand dynamics knowledge conservation planning camp areas.
