Economic effects of riverbank erosion: some evidence from bangladesh.

In this paper I investigate some of the economic effects of riverbank erosion in Bangladesh. The study was conducted in one village over the period 1979-89. Between these dates the village lost almost 20 per cent of its farmland to riverbank erosion. This resulted in a loss of more than 50 per cent of crop income (at 1989 prices). About 45 per cent of households were affected during the period. It appears, however, that there is little understanding among the relevant government agencies and non-governmental organisations of the severity of riverbank erosion in Bangladesh. This article aims to provide, therefore, some basic information on the various economic effects of this natural hazard.
