This paper shows that even the slightly early flood events (1 to 2 wk) that occur with reasonable frequency in north-central Bangladesh are prone to cause significant damage to very low elevation winter rice plots. Yet, our evidence shows that this is not a problem requiring new investments in technology. Rather, credit provision for input financing and extension help with existent shorter duration varieties can go a long way in ameliorating this situation.
