A. Hossain ABSTRACT Abstract: This study presents the present status of food security and ecological footprint, an indicator of environmental sustainability and a computer model of integrated management of the coastal zones of Bangladesh. The study also assesses the climate change impacts on rice production in the coastal zone of Bangladesh. To estimate the present status of the food security and ecological footprint of the coastal zone of Bangladesh, primary and secondary data were collected and the present status of food security and environmental degradation (in terms of ecological footprint) were calculated. To estimate household food security primary data were also collected from all the households of a representative selected village.A quantitative method for computation of food security in grain equivalent based on economic returns (price) is developed and a method of measuring sustainable development in terms of ecological footprint developed by Wackernagel and Rees (1996) is used to estimate the environmental sustainability. Overall status of food security at upazila levels is good for all the upazilas (8.53% to 164.19%) except Shoronkhola (-23.65%), Shyamnager (-6.08%) and Morrelgonj (-30.29%), and the best is the Kalapara upazila (164.19%). But status of food security at household levels is poor. The environmental status in the coastal zones is poor for all the upazilas (-0.5076 to -0.027) except Kalapara (+0.306) and Galachipa (+0.322) and the worst is the Mongla upazila (-0.5076). Environmental status has degraded mainly due to shrimp culture. Developed computer model predicts that expanding shrimp aquaculture industry ensures high food security at upazila levels with increasing environmental degradation.The model also predicts that if shrimp aquaculture industry continues to boom from the present status to super intensive shrimp aquaculture, a collapse of the shrimp aquaculture industry will ultimately occur turning shrimp aquaculture land neither suitable for shrimp culture nor crop production. The control of population and growth of the shrimp production intensity should be considered for stabilization of the system in the long run. The sustainable development of the coastal zone of Bangladesh in the long run without control of both the growth of shrimp production intensity and population will remain mere dream. Crop growth model InfoCrop was used to predict the impact of climate change on crop production in the coastal zone of Bangladesh. Sensitivity analysis shows that the crop model is sensitive to temperature change and CO2 levels.The simulation was carried out to predict the yields of rice under different climatic trends of temperature and carbon dioxide concentration. The effect of temperature on the yield of rice that is negative while of CO2 is positive but temperature plays dominant role. Prediction was also made to predict the climate change impacts of rice yields based on historical and IPCC climate change scenarios. Historical climate change scenario has little impacts on rice yield but there is relatively higher reduction in the yields of rice for IPCC climate change scenario. The model validated with the actual field data and found good agreement between simulated and actual data. ICZM computer model can be used to assist the policy planners to assess different policy issues and to
