Abstract. Jakabaring and its surrounding which is part of Palembang are also experienced a high level exposure to hazard of inundation, where the area is heavily affected by tides which are mostly swamps, consisting of reclamation and protection swamps that are vulnerable to the effects of climate change. This study aims to determine the level of risk due to inundation hazards that occur in current conditions and projected conditions through risk assessment with spatial approaches and adaptation strategies needed, The vulnerability parameters that used are exposure (topography, land use, infrastructure), adaptation capacity (drainage), sensitivity (population density, education level, age, gender and poverty). In the baseline condition, Jakabaring and its surrounding areas is on moderate level of risk. Meanwhile in the projection condition (2030), Jakabaring and its surrounding areas is on high level of risk. The adaptation strategies due to climate change impact that can be carried out are river normalization, drainage normalization, infiltration measure, pumping, green open space, canalization, bio-pore, water retention ponds, multiplying gardens in residential area, roads enhancement, pavement enhancement, polders along rivers, and supervision of swamp regulations.
