Abstract: Since 1960s in Bangladesh many water development projects have been implemented mainly for flood control and boosting the agriculture. Among them Flood Control Drainage and Irrigation (FCDI) projects are significant. Various studies reveal the many positive and negative impacts of these projects. Although these projects were implemented so as to support irrigation for High Yield Varieties (HYVs) rice, but due to bad engineering construction some areas do not get irrigation facilities. As a result serious environmental consequences result in those areas. The consequences of the FCDI projects on the environment of those areas never been examined systematically. This study is an attempt to examine the impacts of FCDI projects on some of the agricultural and environmental components of an area without irrigation facilities. A Mouza named Nischintapur within Meghna-Donagoda FCDI project was selected for the study.

It is assumed that before implementation of this project the characteristics of the environment of the area were almost the same. The FCDI interventions have changed the environment. Therefore, the aims of the study were (1) to identify the impacts of the project on land use, (2) to recognize effects on some of the agricultural components like cropping pattern, intensity, (3) to make a status list of the flora and fauna of the study area; (4) to recognize the cause and effect relationship between the project interventions and IEC (Important Environmental Components) of the study area and (5) to identify the impacts at various environment levels. This study was based on both primary and secondary data. Data were collected from household and Mouza level questionnaire survey, key informants and observation. Mouza map, GIS and statistical methods were used at different stages of the study. The modified EIA method was used for impact assessment of the project in Nischintapur mouza.

The study shows that cropping patterns, cropping intensity and crop diversity have changed in the area. The land use of the area has changed. The physical, biological and agricultural environment has been effected for the lack of water. These have an adverse impact on human life. This study has confirmed and exposed the consequences of FCDI project on environmental components inside the embankment of the area, which does not get irrigation facilities.
