**2. Materials and methods**

The research delved into the state and trend of some key climate related primary and secondary hazards including variation in temperature and rainfall, cyclonic events, salinity intrusion and sea level rise that are affecting the Southwest coast, especially Satkhira district of Bangladesh. Cyclone and storm surge, salinity intrusion and SLR are the key climate induced secondary hazards or disaster that are affecting the coastal communities. It is expected that the vulnerability may be enhanced in the future because of increased frequency and intensity of such events.

The key primary elements including temperature and rainfall of the research district (Satkhira) were collected from the Bangladesh Meteorological Department (BMD) and analyzed to see the trend of temperature over the 35 years long-period (1981–2015) and rainfall over 38 years long period (1981–2018). The research mainly considered at annual and seasonal trend of temperature and rainfall. The secondary literatures collected from different sources were used to analyze the state and trend of other secondary climatic hazards in the southwest coast of Bangladesh. The following sections provide the details of the trend of temperature and rainfall pattern in the study location (Map in **Figure 1**).
