A Study on the Suitability of Polderiza4on in Integrated Coastal Zone Management Programs in Bangladesh Amena Begum Ruma [email protected] Unique Geography of Bangladesh: Exacerbates Tropical Cyclones q The funnel shaped
Bay of Bengal in the
south
q PREVALENCES:
53% of the world’s total
cyclone causalities
occur in Bangladesh
q The710 km of the
coastline faces natural
hazards first.

Ac4vi4es can be included in a sustainable ICZM Programs Polderiza4on in ICZM, Bangladesh q The concept was adapted from the Dutch q Lunched: In 1960s q Total: 123 polders formed by 5,017 km of embankments q 68 polders are ac;ve q Sea-‐facing polders: 49 q Interior polders : 74 Objec4ve and Approaches of the Study OBJECTIVE To assess the suitability of polderiza;on in ICZM in order to determine its major role in respect to natural environment (agroecology), society and na;onal economy APPROACHES q Interview: Engineers of Bangladesh Water Development Board (BWDB), university facul;es q Field studies: Site visi;ng, survey on100 people and photographing three polders in Patenga, Kumira and Sandwip Island in ChiTagong district Polder number 61/1, Kumira ( Sandwip Boat Ghat) A well maintained sluice gate The study area of Kumira – Google map The rubble of the broken protec4ve wall by a ship breaking yard. Polder number 62, Chi]agong city A dis4nct structure 3-‐4 meter high and 10 feet wide earthen embankment ü Protec've wall: Protects the embankment from the Bay of Bangle. ü The en;re polder protects the ChiTagong city and its communi;es Sandwip Island ( eroded embankment) Polder number 72, Sandwip Island Sandwip: Adapted from Google maps
Morphologically a dynamic island at the Meghna estuary. q Earthen embankment q No maintenance for 9 years q 28 sluice gates Assessment and Recommenda4ons ASSESSMENTS Environment: Secures vegeta;on, agriculture Society: Guard the urbaniza;on; reduces crimes Economy : Saves ChiTagong city-‐ the center of country’s trade and commerce RECOMMENDATIONS Emphasize should be g iven on the Integrated Coastal Zone Management incorpora4ng programs led by government, NGOs and local Thank
