“…Since times past, rice fields are the most dominant land in the rural villages of coastal districts. However, due to high profits from shrimp and salt farming, the rice fields are changing to another use [47][48][49][50]. Shrimp farming has affected around 1 million ha of arable land in the southern coastal area [51].…”

“…Billah and Ramhan (2004) have examined the mangrove forests using satellite imagery and found that the largest area occupied by the vegetation was 48.59% in Khulna city. However, due to natural and anthropogenic causes, all vegetation cover has been declining and converted to other land categories [15,50,52,[91][92][93]. A spatio-temporal analysis of satellite images using Normalized Difference Vegetation Index (NDVI) datasets showed that the mangrove forest decreased 15.47% between 1989 and 2010 [94].…”

“…In the Ganges delta area, wetlands increased 500% between 1980 and 2008 [20]. Overall, water bodies increased almost 30% from 1999-2012 in southern Bangladesh [50]. The increasing soil salinity trends indicate threat to agricultural activities as well natural disasters.…”

Land use and land cover (LULC) is dynamic and changes in it have important environmental and socio-economic consequences. The pathways and pace of change vary with space and time and are related to the interaction between human activities and biophysical conditions in an area. This study provides a systematic review of the changing status, patterns, and compositions of LULC in Bangladesh on national, regional, and local scales over the past 85 years. The primary LULC classes in Bangladesh are agricultural land, urban and built-up area, forest and vegetation, water bodies, and wetlands. Most of the country is covered with agricultural land, followed by urban areas; the latter has been expanding rapidly in the area surrounding the capital city, Dhaka, especially the southern capital area. Forest cover is mostly concentrated in southeast Bangladesh, the Chittagong district, and the mangrove forests are predominantly located in the southwest, with the Gangetic delta. High population growth, rapid urbanization, and infrastructure development have been directly associated with changing patterns of land use across the country. In recent decades, urban areas and water bodies have been increasing, to the detriment of both forests and agricultural land. Most of the studies reviewed here describe a general trend involving agricultural and forested land being transformed into urban areas.

“…7 One noted that the increase in salinity could also be related to the level of water in the river at high tide being higher than the level of arable land due to the effects of sediment accumulation on the floor of the riverbed (this following an engineering fault in the construction of the embankment along the coast). It has also been reported that climatic events (sea-level rise, storm surges, tidal flooding, and droughts) and anthropogenic factors (decreasing upstream flow, siltation in the riverbed, shrimp culture, and the construction of the Farakka Barrage in India and coastal embankments in Bangladesh) had increased the vulnerability to higher levels of salinity in the southwestern coastal region (Pouliotte et al 2009;SRDI 2012;Habiba et al 2014;Khan et al 2014;Saroar 2014). …”

The Sustainability of Rice-Based Cropping Systems in Coastal Bangladesh: Bio-Economic Analysis of Current and Future Climate Scenarios

Agricultural sustainability is an issue of great significance for Bangladesh, especially in the vulnerable conditions of the south-west coastal region. This is the case both currently and in light of projected climate and salinity trends in the coastal region. The research reported in this thesis aimed to assess the current and future sustainability of rice-based cropping systems in the south-west coastal region and to identify options to improve the livelihoods and food security of coastal dwellers. To achieve this aim, the research sought to evaluate the contributions of rice and other crops to the agroeconomic viability (profitability and risk) of current cropping systems; to assess the implications of projected future climate and salinity for the economic viability of alternative cropping systems; and to explore the dynamics of farm-level adaptation to changes in climate and salinity.The farm household was taken as the basic unit of analysis and conventional techniques of farm management research (partial, enterprise, whole-farm, and stochastic budgets) were used, supplemented with the results of climate and crop simulation models to project economic viability in future scenarios. Tools from rural livelihoods analysis were also applied to the study of household adaptation strategies. Two contrasting villages in Dacope Sub-district were chosen for the research.In Shaheberabad arable land was widely used for rice and non-rice cropping, while farmers in Uttar Kaminibasia practised rice/fish farming in the wet season and brackish-water shrimp farming in the dry season. Four household types were identified -large, medium, small, and landless -to capture the range of circumstances within each village. A range of quantitative and qualitative techniques were used to collect data from these villages and household types, including group interviews, key informant interviews, household case studies, and household questionnaire surveys.Rice farming was the most important livelihood activity in the wet season in both villages, providing food, cash, and employment. In the dry season, the rice fields were used for a range of non-rice crops in Shaheberabad or for brackish-water shrimp in Uttar Kaminibasia. In addition, homestead gardening, aquaculture, and livestock rearing were undertaken, more in the first village than the second. Wage employment and/or self-employment activities were also integral to the livelihoods of most households. This diversification itself contributed to sustainability.The currently-practised rice/non-rice and rice-fish/shrimp systems were economically viable given typical seasonal yields and prices. However, seasonal variability in yields and prices affected the profitability of the cropping systems. The profitability of dry-season crops in Shaheberabad was frequently affected by climatic stresses (erratic rainfall and drought) and soil salinity, due mainly to inadequate access to freshwater irrigation. Likewise, the profitability of shrimp in Uttar Kaminibasia iii was affected by climatic...
