Fast Action for Floods: RCT Evidence on Forecastbased Cash Transfers from Bangladesh and Nepal

As increasingly frequent extreme weather events disrupt lives, institutions are turning to earlywarning systems and advance preparation to accelerate aid delivery. We present evidence from a randomized controlled trial in Bangladesh and Nepal testing whether providing cash within days of a flood leads to greater benefits than delivering the same assistance months later—or if it simply shifts the timing of benefits without improving overall welfare. Results suggest that timely cash assistance leads to overall gains in food security and psychosocial well-being. This evidence supports efforts to forecast crises and release disaster relief quickly.
