The assistance under the ‘Coastal Embankment Improvement Project’ will upgrade the country’s embankment system by increasing the area protected in polders from tidal flooding and frequent storm surges in six coastal districts.
With the approval of the project, the World Bank’s total concessionary lending to Bangladesh reaches $1.6 billion in FY 13, said a release of the World Bank.
The credits from the International Development Association (IDA), the World Bank’s concessionary arm, have 40 years to maturity with a 10-year grace period and carry a service charge of 0.75 percent.
The release said that the project would rehabilitate 17 polders in six coastal districts – Bagerhat, Khulna, Satkhira, Barguna, Patuakhali and Pirojpur. The rehabilitated polders would provide direct protection to the 760,000 people living within the polder boundaries.
Besides, around 8.5 million people living in these six coastal districts would also benefit through agriculture development, employment and food security.
“Climate change is no longer only an environmental issue; it is a development issue,” said Johannes Zutt, World Bank Country Director for Bangladesh and Nepal
“Adaptation to increased risks from climate-induced weather events is essential for development in Bangladesh. The project takes account of climate change induced sea level rise and increase in the intensity and frequency of tidal surges and floods while designing and climate-proofing the polders,” he added.
The coastal zone spans over 580 km of coastline in Bangladesh where 28 percent of the country’s population reside. A higher percentage of population lives below absolute poverty line in the coastal area compared to the rest of the country.
The World Bank release also said that the project will help reduce poverty and stimulate economic development by facilitating the growth of farm and non-farm activities in the coastal area. The project would support increase in agricultural productivity as the reconstructed polders would prevent intrusion of saline water.
A recent World Bank study on the cost of adapting to extreme weather estimated that currently 8 million people are vulnerable to inundation depths greater than 3 meters due to cyclonic storm surges.
This number will increase to 13.5 million by 2050 and by an additional 9 million due to climate change. Rehabilitating and upgrading the height of the polders will enhance the resilience of coastal areas to cyclones, tidal and flood inundations, and salinity intrusion.
This in turn will enhance the people’s livelihoods through increased agricultural production during normal weather and reduced loss of life, assets, crops and livestock in the event of a disaster, the study said.
Embankment improvement will probably increase the height of the embankment. In doing so, width at the top and the base will naturally increase. A new design of the embankment may be thought besides traditional engineers design. By new design, I would like to say that a combination of agriculture, forestry, cottage industry with local vulnerable peoples participation in execution, management is considered. The responsibility of maintenance and stabilization of the embankment slopes, berms etc is shouldered by the local participating groups. Some cultivars in agriculture and salt and water tolerant mainland tree species besides mangrove species be practiced with the embankment stabilization keeping in view the protection measure against water rise, tidal surge,storm , regular employment and financial benefit to the participants.
