The paper shows current climate change scenarios for Kalapara, analyses the relationship between climate change scenarios and adaptation of relevant measures and strategies by the cultivators which adequately helps in reducing the risks of climate change and improves livelihoods. It also described the adaption strategies to climate change and their application for food security. Historical changes in the weather pattern by different natural disasters like food, storm surge, drought etc. have any impact on the agricultural practices of that District and how the adaptation option are rightly utilized that has been analyzed in this paper. To support the analysis a questionnaire survey was conducted to gather farmer perceptions of what different strategies should take to fght against the climate changes with some demographic conditions of the farmers’ families. The paper presented that the education level of the present generation of farmers is gradually increasing and they have perceptions that show the temperature is rising, timely rainfall is not available and crop production seasons are shifting. The adaptation measures followed by the local people are increasing their capability to fght with climate change problems and with the course of time the food security of the area is enriched. Impact of Climate Change on Food Security in Bangladesh Md. Humayun Kabir 1 , Zobaer Ahmed 1 and Rabia Khan 2 * 1 University of Dhaka, Bangladesh 2 Kohat University of Science and Technology, Pakistan Keywords: Food security; Climate change; Fossil fuels; Ecosystems; Agriculture; Green-house Introduction Across 250 years, deforestation, combustion of fossil fuels, and production of agricultural yield atmospherically; the concentration of carbon dioxide (CO 2 ) and diferent greenhouse gases to rise considerably. Climate change has gain world attention because it evolves as the most important challenge of the century. Climate change defnition is inevitable in the foregoing; it means all changes within the climate as a result of human activities or natural variations [1]. Te planet is encircled by layer of gases that act just like the glass wall (earth blanket) and ceiling of green-house. Tese questionable greenhouse gases are important to sustain life on earth. Tey let the sun ray penetrate however, stop abundant of the warmth from escaping, keeping the earth heat enough to permit life. However, drawback that we tend to face these days is that the blanket of the green-house gases that happens naturally within the layer is apace obtaining thicker resulting from increased emissions of greenhouse gases and this lead to the speedy warming of the world’s climate. Climate change, apparently is change within the mean values of climate measure by component such as; rain, temperature, over long amount of your time typically ffy years, (climate change/global climate change/temperature change) is that the important change within the state of the climate of an area that may be known by change within the mean associated or within the variability of its properties that persist for an extended amount inefably decades or longer IPCC (2011). Temperature change may be a phenomenon that has been accepted globally as a truth of life. Tis implies that it is a matter of indisputable fact that can continuously be subjected to natural dynamism or changes. Tere are many assumptions and have been made from a wide range of climate model simulations for example, the scenario assumes that humans worldwide are likely to make more sustainable development choices if wider range of technologies for producing energy with greater efciency will be used in the future. Carbon emissions are forecasted to be increased from current rate of around 9 billion metric tons each year to around 12 billion tons each year until 2040, and afer that it will again gradually decline to 5 billion tons each year by the year 2100 [2]. Te main reason for this temperature increase is carbon dioxide and other heat-trapping “greenhouse” gases that human activities produce. Te biggest source of added carbon dioxide is from people burning coal and other fossil fuels. Climatic changes are putting very negative efect on many things such as herbs like Satu, silajit, Bhase, timur, amala, panch aule, ritha, bel are deteriorating and transferring to higher altitude ranges whereas green grass has also deteriorated severely in the Himalayan region of Mustang [3]. On the other hand, fast increase in greenhouses has both positive and negative efects on people, society, and the environment-including plants and animals because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years afer being released, their warming efects on the climate persist over a long time and can therefore afect both present and future generations [4]. Consequently, the rate of change today is unprecedented in human history. 21 st Century ecosystems and their component species are faced simultaneously with fragmented landscapes and climate change, not allowing species to adapt to new conditions [5]. Tracing this back into antiquity; Asian nation may be a playground country of ofentimes stirring natural disasters and these natural disasters became moniker to Asian nation, disasters like droughts, coastal erosions, fooding, tropical cyclone and storm surges [6]. Food security is the state achieved when food systems operate such that “all people, at all times, have physical and economic * Corresponding author: Rabia Khan, Kohat University of Science and Technology, Pakistan, Tel: 0922-52914674; E-mail: rabia.pk123@gmail.com Received July 11, 2016; Accepted August 25, 2016; Published September 03, 2016 Citation: Kabir MH, Ahmed Z, Khan R (2016) Impact of Climate Change on Food Security in Bangladesh.
