A STUDY ON THE AEZ BASED ROAD-TRANSPORTATION ENGINEERING ON THE BIO-DIVERSITY AND FOOD SECURITY IN DISASTROUS AREAS OF BANGLADESH (Pages : 118 - 123)

Bangladesh has 30 Agro-Ecological Zones (AEZ) as per its climate and environment by UNDP considering climate change parameters, natural resources and food security for bio-diversity sustenance. A study was conducted with AEZ Based road-transportation engineering on the bio-diversity influencing food security stability. The road transportation engineering integration consists of the bridge designs impacting bio-diversity. It was done with the objectives studying the physical communication systems evaluating the Bridge Maintenance and Management Systems (BMMS) and bio-diversity command area impact information. The works were done thus to develop a non-pillar-bridge avoiding water stagnation. The results indicated that the road-bridge-transport integrated system contributed negatively for food security and bio-diversity indicating environmental degradation. The Bridge-Culvert dimensions were found inadequate to drain out the command area water causing bio-diversity based production found loss. The most structures had middle pillars reducing the water streams. The results showed that about 74% of the bridges lost its full functions increasing water stagnation up to 63%. The food security decreased up to 21% by last 5 years. Having being recognizing the ill effects of unplanned transportation engineering, a model bridge design was developed enabling 24% more water drainage and reduced food oriented bio-diversity destruction by 14%, recommending further studies in other critical areas.Download
