Climate change adaptation being one of today’s main challenges on global agenda do affect people worldwide, but even though most decisions regarding climate change governance are made at the international or national level, the implementation of these decisions in most cases takes place at the local level. Municipal climate change adaptation research project in Latvia was carried out with special emphases on main stakeholder understanding, preparedness and communication factors using several complementary research methods – case study research in Salacgriva coastal municipality, sociological surveys with both Salacgriva town households / inhabitants (home visits / questionnaires) and also nation-wide municipal planners/ specialists survey (web based) in Latvia, as well as complementary interviews with various national agencies governance level experts. The comprehention and level of understanding of all sectors and necessary elements of complex municipal climate change governance development in Latvia is not sufficiently high neither for municipal planners/specialists nor for municipal (flood endangered) households, according to the needs of both those groups. There is in Latvia diverse and wide list of separately developed and already available instrument groups for municipal climate change governance (MCCG), especially, complementary communication instruments, as well as suffient enough number of insturments are in possession of the any particular municipality, but usage of them is quite limited by their type and range, and not complementary. Necessary is to change municipal project type thinking-working towards comprehensive planning / programming municipal development / support and pro-active communication and collaboration.
