Cities can leverage input-driven institutional change even without national support for climate change adaptation or mitigation. For example, where cities have defined policymaking and budget raising powers, city level political leadership can support adaptation action going beyond national policy . Examples include the Surat Climate Change Trust in Surat, India  and Initiative for Urban Climate Change and Environment in Semarang, Indonesia . In Saint Louis, Senegal, support from national and state-level actors enabled local institutional change . Processual levers may be also mobilised in situations of political instability , clientelism   or in contexts where there are high political and socioeconomic inequalities .
