Bangladesh called the land of water as many as 310 rivers crisscross all over the country and source of surface water use. However, these natural resource base has been neglected in policy as a result many rivers in the country are about to dead and some are biologically dead because of anthropologic cause. Further, irrigation water used from this river and direct disposal of industrial chemicals and other waste polluted the land and reduces productivity and seems to ominous link to food insecurity. The present paper focuses and try to explore land and water pollution and its relationship with food security. The findings and outcomes of this paper is a research in a riverside village in Bangladesh and the methodology used for this study are focus group discussion (FGD), individual interview, observations, secondary information and review of literature.
