Introduction Bangladesh is frequently affected by cyclones and storm surges (Karim 1995, Alam et al. 2003, Islam and Peterson 2009). Besides flood and cyclones, Bangladesh is also vulnerable to many slow onset disasters. It is greatly feared that Bangladesh will be highly affected by sea-level rise and saline intrusion (Milliman et al. 1989, Sarwar and Khan 2007, Sarwar 2013). The country is also vulnerable to drought (Habiba et al. 2012), erosion (Sarwar and Woodroffe 2013), salinity (SRDI 2010) and landslide (Sarwar 2008). The geographic status of Bangladesh has made it one of the most vulnerable countries to climate change among the South Asia developing member countries (DMCs) of ADB (BCCSAP 2009). Frequently occurring natural disasters, high population density, poor infrastructure and low resilience to economic variability make Bangladesh even more vulnerable to climate variability and changes. Different parts of Bangladesh suffer from various natural disasters such as flooding, river bank erosion, drought, flash floods, forest fires, landslides and tropical cyclones. The coastal belt has historically well-known large cyclones and surges. Climate change and sea level rise will worsen this scenario of cyclones in the near future (Sarwar 2013). Other disasters include tornadoes, hailstorms and lightening which are projected to be more frequent and intense because of global warming. This project will encompass a survey of data required for climate risk screening and climate risk and vulnerability assessment. ADB developed a climate risk screening system in 2013 which was applied in South Asia developing member countries to evaluate the level of risks. The screening report provided by the ADB tool includes a preliminary evaluation of climate/ weather- related as well as associated geological and geophysical risks. The medium or high risk projects face further screening through dedicated screening tools. Temperature increase, precipitation change, wind speed change, sea- level rise, solar radiation change, water availability, flooding, tropical storms, wildfire, permafrost, sea ice, snow loading, and/or landslides can be considered as hazard components of risks (ADB 2014). These risk assessments can be in forms of risk overlays, thematic maps generated by index and/ or criteria-based methodologies and their combinations. Project lifespan, design, and efficacy can be affected by the risk assessment which may lead to recommendations on strategic and co- beneficial climate change adaptation and disaster risk reduction and management options. However, spatial data is very important to carry out such vulnerability assessment. Spatial data in Bangladesh is scare and maintained by various organization with inadequate cooperation among themselves (WAPRO 2012). 7 The main objective of the report is to develop HEVR spatial databases for CRS and CRVA study. To perform the task, data from various organizations is required. In order to develop HEVR spatial databases, the consultant team has visited different organizations and is collecting the spatial and non-spatial data from different sources such as- Ministries/Departments/Agencies which was previously listed through scoping study. By this time the team has achieved a significant progress in collection of data required for development of HEVR spatial databases. 2. Coordinate and consult with relevant organizations for sourcing and collection of spatial data 2.1 Organization visits: For the development
