📒 Southwest Area Integrated Water Resources Management Project (SWAIWRMP) aims to rehabilitate and upgrade the existing flood control and. drainage/irrigation (FCD/I) schemes located in the Southwest region of Bangladesh, thereby achieving their maximum development potentials in terms of agriculture production, fishery production and incomes of the beneficiaries in a sustainable manner. Traditional environmental impact assessment (EIA) usually focuses on single-project development undertaken by single proponents in a narrowly defined physical area and defined time frame. The EIA carried out by SWAIWRMP eventually didn't address the cumulative environmental impact. That is why cumulative impact assessment especially for water sector project is very important and essential. There are a number of existing and proposed infrastructures in the Sub-Project area, which might have cumulative impact. This study has assessed cumulative impact for the compartment one of SWAIWRMP.
