GoB has undertaken the implementation of the Coastal Embankment Improvement Project (CEIP) with loan assistance of the World Bank (WB) and grant assistance of the Climate Investment Fund’s Pilot Program for Climate Resilience (PPCR). The Project includes rehabilitation and improvement of 17 polders, to be implemented in the Khulna and Barishal Division of Bangladesh. As per requirement of Environmental Conservation Rules and demand of the World Bank safeguard policies, an Environmental Management Framework (EMF) has been formulated which includes various steps for protection of physical, ecological, socio-cultural resources along with economic development and protection of occupational health and safety (OHS). These steps are to be followed during all phases of the project cycle to address environmental considerations, which are much out looking and may be adopted in all types of construction work in Bangladesh.

Key words: Eco-friend practices, construction work, coastal polder, photograps.

Introduction
Global warming is an important issue, with a variety of influences on agriculture, water, health, and economy. It is now recognized that climate variability and extreme events affect society more than changes in the mean climate (IPCC, 2001). Bangladesh a climate variability country is vulnerable to current coastal hazards and anticipated Sea Level Rise (SLR) because of its lower elevation. WARPO (2006) predicted that the Sea Level Rise (SLR) may be increased by 14, 32 and 88 cm in 2030, 2050 and 2100, respectively which may inundate about 8, 10 and 16% respectively of the total land mass of Bangladesh. DOE (2001) predicted in several studies that the sea-level in the Bay of Bengal may rise in the range of 0.3 to 1.5 m by the year 2050. Saline water intrusion is highly seasonal in the coastal area of Bangladesh. Salinity and its seasonal variation are dominant factors for the coastal ecosystem, fisheries, and agriculture. Therefore, any change in the present spatial and temporal variation of salinity will affect the biophysical system of the coastal area. So, in the 1960s, modernization started in the coastal zone of the country to convert this area into permanent agricultural lands to increase agriculture production. The polders in this area are enclosed on all sides by dikes or embankments, separating the land from the main river system and offering protection against tidal floods, salinity intrusion, and sedimentation. Without embankments, the coastal communities would be exposed to diurnal tidal flooding. The polders lands are slightly higher than sea level. These Polders are equipped with inlet and outlet sluice gates to control the water inside the embanked area. The Polders have been playing a vital role in safeguarding the coastal area; ensuring and increasing agricultural production; improving livelihoods of the people; and mitigating environmental damages. But these are vulnerable to storm surges; high tides; annual floods; land erosion and drainage congestion. In many cases, the structures as built have not been found adequate to cope with the diverse needs of the local people. Changes in the land use pattern have created water management conflicts and newer dimension needs asking the structures to allow water to flow in both directions. So, maintenance of the polder system with embankments and structural elements has become of permanent importance. The GoB either with assistance from international donors and lending agencies or out of its own resources has been spending money almost on a regular basis to keep the Polders in good working condition eventually to save the coastal people. The Coastal Embankment Improvement Program (CEIP) implementing by Bangladesh Water Development Board (BWDB) is one of the latest such interventions to address a systematic
