dc.description.abstract | Natural disasters and land-use change are major concerns all over the world, and if these two
concerns exist together in a coastal area, then the consequences for people and the environment
may be severe. This study investigated the changes in land-use in the past 10 years in
Shyamnagar Upazila of the south-west coastal area of Bangladesh. The drivers of land-use
change and the occurrence of disasters were explored in relation to their effects on social and
ecological systems. Satellite images were analyzed to detect changes in land-cover in the last 13
years. Three areas were selected for on-the-ground data collection. Household surveys were
conducted to discover the type, level and effects of disasters. Focus Group Discussions and
personal interviews were also conducted to explore the drivers behind changes in land-use.
Probability regression analysis was performed to assess the relationship between various
disasters with overall income, agricultural production and outward migration. Results from
image analysis showed an overall 21 percent increase in shrimp culture ponds in the past 13
years. Agricultural land and forest resources decreased by 48 and 3 percent, respectively, while
barren and built up areas increased by 71 percent. Analysis of household data showed that
cyclones and tidal floods had significant effects on income, agricultural production and
migration. Social, economic and political factors combined with natural causes were found to be
the main drivers behind land-use changes. These empirical findings suggest that social and
ecological resilience was reduced and vulnerabilities increased in this part of coastal Bangladesh
for these reasons between 1999 and 2012. | no_NO |
