LAND USE CHANGING PATTERN AND CHALLENGES FOR AGRICULTURAL ACTIVITIES: A STUDY AT DUMKI UPAZILA, PATUAKHALI
Abstract
This study was carried out to explore the changing nature of land use pattern and major
challenges for agricultural activities of a coastal Upazila (sub district) of Bangladesh. Both
primary and secondary data and information were used in this research work. 20-year span
(1998-2018) was considered to study the changing nature of the land use pattern. This study
revealed that the land use pattern of the surveyed household has gradually been changing.
Agricultural land has been decreased 4% during the last 20 years because of building new
houses, selling or mortgaging land for fulfilling monetary needs, distributing land among the
successors, reducing soil fertility, wearing away land parts by riverbank erosion, and acquiring
land by the government. This study also found insect nuisance/disease, loss of fertility, and
excessive rainfall and irregular flooding as the key environmental challenges for agricultural
development. The surveyed households were fighting with these challenges by way of their
own mechanisms i.e., using pesticides, insecticides, and medicines for controlling insects and
diseases, keeping the land as fallow or cultivate in the off season to adapt to flooding or
excessive rainfall, using powerful fertilizer and saline tolerant crops to adjust with soil
infertility as well as soil salinity problem. Similarly, they also were provided with seeds,
fertilizers, insecticides, training, agricultural tools, loan, and advices together with
technological supports by different governmental and non-governmental organizations. In
addition, respondents of the study area were seeking for good drainage and sluice gate systems
as well as an irrigation system to minimize the impacts of excessive rainfall, flooding and soil
salinity problems
