Abstract | Geographically speaking, Bangladesh is a small country but bears a huge population resulting in a very high density of population and very high intensity of land and resource use. Per capita land is estimated to be about 13 decimals only. Two significantly prominent phenomena drives country’s overall scenario of economic development and environment imbalance are the high growth rate of population engulfing precious land for settlement and scarcity of land for ever increasing demand of food. Every year country is losing 1 percent arable land. Due to the population growth its infrastructure use is increasing and agricultural land is decreasing gradually. Rajshahi District was selected as study area because of its relatively higher growth in infrastructure development under various regional development programs. For analyses of land use pattern and its change remotely sensed data (Landsat MSS-1977, TM-1990 and TM- 2010) and GIS techniques was used.The methodology of the current research included secondary data collected from SPARRSO, published and unpublished data regarding crop, population and other ambient information from mostly government sources. The data (spatial and attributes) were analyzed by GIS and statistical tools and through tables of various natures.It was found that the land use pattern of Rajshahi District is changing. Among various causes of agricultural land losses the infrastructural development is the most important cause. The agricultural land of the study area is losing 0.46% per year and area under infrastructure use is increasing 5.86% per year. If this rate is steadily progressing, within next 217 years the agricultural land will be totally empty. |
