The fragile and conflict-affected situations (FCAS) and small island developing states (SIDS) approach represents a new way of doing business for the Asian Development Bank (ADB) in its most vulnerable developing member countries. FCAS and SIDS face unique development challenges such as a greater need for governance and institutional capacity building, geographic isolation, small populations, narrow asset bases, and armed conflict. The FCAS and SIDS approach—or FSA—introduces flexible processes and procedures that will allow ADB to tailor interventions to the specific challenges of these countries, with the goal of improving project results, and ultimately improving livelihoods.
