Abstract
Due to alterations in physiographic and social-economic conditions, climatic changes, adaptation and population growth, the land utilization of Bangladesh is changing very rapidly. Small farms and landless household constitute about 80% of total area households, the majority of whom depend on agriculture for their livelihood. It is obvious that total agriculture land over the periods in the past has not increased although population has increased significantly [12]. Bangladesh is a small country but it bears a huge population, resulting in a very high density of population and very high intensity of land and resource use. Based on secondary data of Bangladesh Bureau of Statistics, an attempt has been made in this paper to evaluate the changes in land use pattern during the period of 1990 to 2015. Absolute utilization of land for different purposes during this period as well as trend values and growth rates were estimated. Trend analysis and exponential growth rate showed that forest area significantly increased by 35.93% and 0.3% per annum and land not available for cultivation is significantly decreased by 4.49% and 0.04%per annum respectively. Result also show that cultivate waste is significantly decreased at the rate of 1.1% per annum. On the other hand, a current fallow is decreased by 0.2% per annum. The trend values was found statistically significant for land use in forest and cultivate waste.
Highlights
Bangladesh is one of the least developed countries of the world, and is mostly rural and agricultural
As agriculture is the dominant sector of the economy, land enjoys the highest importance as a resource
Another important aspect of land is that the rapid growth of population in a somewhat stagnant economy puts tremendous pressure on land, thereby adding scarcity value to a natural resource which is already in great demand
Summary
Bangladesh is one of the least developed countries of the world, and is mostly rural and agricultural. As agriculture is the dominant sector of the economy, land enjoys the highest importance as a resource. Another important aspect of land is that the rapid growth of population in a somewhat stagnant economy puts tremendous pressure on land, thereby adding scarcity value to a natural resource which is already in great demand. Land use pattern of a country reflects its socio-economic stipulation. While land use changes are concerning topics in perspective of socio-economic changes of a country, the pattern of its changes in Bangladesh is to meet the dynamic demand of the society that creates pressure on natural environment.
