Study area: Bangladesh is surrounded by India (west, north and eastern side), Myanmar (South-eastern side), and Bay of Bengal (Sothern side). Although it is a small country, it has distinct physiographic diversity where 12% land belong to Pleistocene land, tertiary hilly area (8%) and plain land (flood plain and deltaic land) 80%. More than 700 river cuts across the country and drainage system, 79% dominated by three main rivers: Ganges Brahmaputra-Meghna (GBM) and their tributaries river and overflowed in monsoon. Being a tropical monsoon climatic country, there is fairly marked seasonal variation with frequently high rainfall difference between seasonal temperatures in hot and humid summer (March to June), hot, humid, and heavy rainy monsoon (June to November), dry winter (December to February) with low temperature.
Bangladesh has a monsoon climate with a hot, rainy summer (suitable for Aman rice, Jute) and a dry winter season suitable for Boro rice, wheat, potato, maize. In the country, rice is the dominant crop and and contributes 70% of calories consumed, so rice management intervention has been a focus of food security activities. For the causes of climate, suitable rainfall, temperature, and soil type, Bangladesh can grow plenty of rice all over the year. Rice has wide adaptation ability under different agro-ecological niches of the country. For its distinct characteristics, it can be cultivated from slope of the hill to a very deep flooded area where water depth rises around 3 m (Nasim et al., 2017). The study area is also a disaster-prone area that almost all over the year happens in the country meanwhile different regions are affected by different disasters.
METHODS This research was conducted based on secondary information collected from different organizations. Both spatial and non-spatial data were collected for visualizing the distribution pattern of crop production in Bangladesh. Therefore, challenges of food security were scrutinized through related literature. Finally, based on the distribution pattern and constraint of food securities, some pathways were proposed for attaining sustainable agricultural development.
Data collection Data on the distribution area of three main types of rice as, Aman and Boro rice were collected from the Bangladesh Bureau of Statistics (BBS) of 2016. The data of the distribution area of wheat, potato, and maize were collected from the Yearbook of Agricultural Statistics (2015) agricultural production data from FAO’s country profile . The collected data were arranged in Excel format before preparing the map of the distribution area of the main crops of Bangladesh in the year 2016 using Arc GIS. It also shows the diversity of crops and crop-dominated area by proportion of cultivated area. Finally, the maps show the crop distributed area all over the country of one cropping year.
