We have visited Arial Beel, Munshiganj on the 02 December 2011 as part of RDM 501: Principles of Environment, Natural Recourse and Disaster Management course requirement. Our accompanying faculty was Raguib Uddin Ahmed. We started from Dhaka on at sharp 8:30am and it was day long field visit. On that day we visited mainly four different sites: two landfill areas those are for human settlement and industrial purpose, other one is a random selected village surrounding arial beel and finally Baggakul ghut, near Padma river, Munshiganj for understanding how Landfill is causing for wetland loss, Beel ecosystem and Riverine ecosystem. We also covered our task by identifying surrounding biodiversity characteristics, different animal and plant species, present management system etc. We started for Dhaka at 5:30 pm.
