      abstract = {Two competing flood control and drainage management (FCDM)  systems, namely, the ‘silt-dredging and regulative-drainage  management (SRM)’ and the ‘tidal river-basin management  (TRM)’ systems were implemented in the Southwest coastal  zone of Bangladesh as a safeguard for agricultural  production. The fundamental difference between these two  FCDM systems is that the SRM is a conventional system based  on hard engineering structure and heavily dependent on  routine dredging; in contrast, the TRM is a natural system.  This paper primarily evaluates these two contrasting and  competing FCDM systems from the perspectives of productive  efficiency, going beyond the traditional approach which  often takes an engineering perspective. Evaluation of these  two FCDM systems has been made on three distinctive  measurements including ‘technical efficiency’, ‘yield-gap’  and ‘potential yield increment’. The results reveal that  the conventional flood defence system (SRM) marginally  outperforms the natural system (TRM) in terms of  productivity with paddy. This is despite SRM being more  expensive to deliver, as well as the fact that, due to a  relative sea-level rise with the SRM system, it is likely  to become increasingly expensive in the future. In  contrast, TRM benefits from counteracting a relative  sea-level rise in an environmentally friendly way, keeping  maintenance costs low.},
