Mitigation garners the significant share of committed climate finance. For example, of the total USD 15.4 billion climate finance commitments through 'green bonds', 79% accrued to mitigation and the rest to adaptation . However, within adaptation finance, water garners a significant share of adaptation funds, with 13% of the Adaptation Fund's investments were for water management, 12% for coastal management and 10% for disaster risk reduction . Similarly, within the urban adaptation landscape, which got ~3-5% of total adaptation finance flows of USD 30.8 billion tracked in 2017-2018 , water and wastewater management projects received the largest share of urban adaptation finance  followed by disaster risk management  . However, more frequent tracking of public financing is required, with a greater focus on transparency and accountability  and justice and social equity  .
