Naimur Rahman* Department of Geography and Environmental Science, Begum Rokeya University, Rangpur 5400, Bangladesh Abstract Cropping pattern means the proportions of area under various crops at a point of time. This paper provides a comprehensive assessment of crop pattern, crop productivity using climate, water and crop yield models. The existing studies present that climate change models with higher spatial resolution can be a way forward for future projections. Various types of statistics, other secondary data and primary questionnaire method was applied to measure and analysis the problem. The cropping pattern differs from macro to micro region, both in space and time and is governed largely by the physical, cultural and technological factors. For the purpose of agricultural regionalization and planning, it is necessary to divide the area/ region into homogeneous region on some well-defi ned basis. Increased crop production could be expected if the irrigated areas expansion prevails. In addition, it will lead degradation of the environmental phenomenon. The different crop pattern of this region varies the diversifi cation of several discussed strength including soil, erosion, fl ooding, waterlogging, precipitation, source of irrigation and others. The areal unit of crop ranking is the dominant variables for fi rst, second and third ranking. The importance of adoption of suitable cropping patterns in a developing country cannot be over emphasized. The horizontal expansion of agriculture is not possible without heavy capital investments. If the encouraging method does not get proper result for two or multiple crop pattern for extended areas of land then the food security could be ensured by zonation of crop pattern or judicious regulation. Introduction behavioral approach in geography, because it refl ects the performance of the farmer for various crops sown in an Agriculture is one of the leading occupation in Bangladesh agricultural fi eld. Hence, by considering the facts related and it plays a vital role in shaping the economic condition of to better cropping pattern, the present research has been the farmers as well as the whole country. It contributes about attempted to analyzing the irrigation facilities, cropping 14.10 (2017-2018) percent of total GDP. Agriculture provides pattern, crop ranking and crop combination. food to the masses, green fodder for livestock and supplies raw material to various agro-based industries. Hence, systematic, The pattern of cropping system could be demonstrated scientifi c, and proper cropping pattern and crop combinations through soil agro-ecological measurement as well as climatic are the most important aspect for better out-put in agriculture. condition of a region [1]. Cropping pattern indicates the proportion of area under various crops at a point of time whereas the crop combination indicates Nevertheless, at farmers’ level, potential productivity and to grow different types of crops under the same agriculture fi nancial edges act as guiding principles whereas choosing a fi eld.
