In the wider context of several primary climate change impacts affecting low-lying coastal areas of Bangladesh, this article examines how the phenomenon of ‘climate change migration’ creates national and local secondary complications for internal population displacement as well as increasingly visible tertiary impacts. These are manifested in rapid urbanisation and precarious socio-economic and environmental changes in urban contexts. Highlighting the growing interconnection of climate change, migration and urbanisation in Bangladesh, the article calls for effective local policy changes to address the urgent need to safeguard sustainable livelihoods and security of fundamental rights for climate change migrants.

This study intends to explore the extent of the use of information and communication technology (ICT) in flash-flood-prone haor (wetland ecosystem) areas of north-eastern Bangladesh. Addressing the situation of severe flash floods in 2017 at the community level, this study aims to examine the constraints and challenges in using ICT for flash flood risk management. An empirical study was conducted in two upazilas (administrative sub-districts) within the Sunamganj, the most affected district. A total of 120 household heads were interviewed using a semi-structured questionnaire. Focused group discussions (FGD) and key informant interviews (KII) were also used. Results reveal that people in these areas do not use computers or Internet. However, the use of mobile phones is common for communication during disasters. Illiteracy, poor quality of life, poor social capital, poor infrastructure, and poor communication with institutions are highlighted as the main constraints and challenges in the effective application of ICT in flash flood management. The results showed that the local community people of the study area receive early warning and hazards preparedness-related information through mobile phones, television, radio, and Facebook. However, the results also highlighted the constraints and challenges in applying ICT in DRR at the community level. By addressing a remote region and a relatively less focused disaster (flash flood), this study contributes to boosting the application of ICT in DRR, especially in remote, disadvantaged communities.

Reckless construction and overextraction of resources have placed tremendous stress on the Sultanate of Oman's coastal ecosystems at Al-Batinah. The rate of sea level rise (SLR) intensifies under the multiple effects of environmental and social pressure. A projected 2 m SLR, for example, would inundate 200 km ² of land and impact the Sultanate's entire socioeconomic growth cycle and coastal ecology. The coastal land-use impacts, calculated through Landsat satellite images and census data, are used to explain the effect of SLR on coastal land uses and ecosystems. The Sultanate of Oman's comprehensive coastal zone management (CZM) planning and practices have limitations when seeking to reduce the burden on coastal system-linked socioeconomic growth and environmental issues. The study documented in this article addresses the challenges of the Sultanate's CZM practices and proposes an integrated coastal zone sustainability management framework.

Climate change has introduced a new social group called ‘‘Climate migrants’.’ In 1995, approximately 25 million people worldwide were considered to be environment or climate refugees, it is anticipated that this number will have increased to 200 million by 2050. Bangladesh is one of the countries highly exposed to extreme ‘‘climate’’ and an appropriate place to study climate-induced migration. With an empirical field research through stratified sampling techniques amongst migrants, this article examines the drivers of migration, impacts on individual and family livelihoods of the explosion of climate migrants to analyse how consideration of this growing body of climate migrants fits with traditional migration theory.
