Environmental and Socio-economic Impacts of Salinity Intrusion in the Coastal Area: A Case Study on Munshigong Union, Shymnagor, Satkhira

Abstract

One of the major problems in the coastal zone of Bangladesh is Salinity intrusion. It is increasing alarmingly due to natural and anthropogenic reasons. salinity. Salinity is causing decline in soil productivity and crop yield which results in severe degradation of bio-environment and ecology. So, a study has and socio-economic condition of the worst salinity affected Munshiganj union of Satkhira district. The study was conducted on the basis of primary and secondary both data sources. To collect pri different methods had been adopted which were informal interview, a pre and Focused Group Discussion (FGD). It has been found that salinity increase results in reduction of agricultural production, vegetation grow environment and creating negative impact on the socio Moreover, in maximum cases people of the study area are changing their occupation such as f shrimp farming, prawn collection, shopkeeper, labor etc. including cultural changes. Different kinds of diseases are also spreading and food habit changing. A great concern is found that there are no any kinds of drinking water without saltiness. In this perspective, some time oriented immediate steps have to take to protect salinity intrusion and to find out suitable ways to adapt with salinity problems with the collaboration of Government and local NGOs.

Issues with families and children in a disaster context: A qualitative perspective from rural Bangladesh

“…One sub-district from each identified district and three unions from each sub-district were selected though a field analysis of these three districts. Study villages were selected purposively based on earlier studies, which indicated vulnerability of all three locations to multiple and frequent disasters [18][19][20][21][22][23][24]. Considering such vulnerability, these study areas were selected to represent flood, cyclone and water logging in order to explore the variations in awareness among inhabitants of different locations.…”

Influence of Rice Straw Incorporation on the Microbial Biomass and Activity in Coastal Saline Soils of Bangladesh

“…Salt in soil is one of the most important environmental problems of Bangladesh. Reduction of freshwater flow from upstream causes salinity intrusion and salinization of ground water in Bangladesh [1]. The coastal area covers about 20% of total land and over 30% of the net cultivable area of Bangladesh [2].…”

“…The coastal area covers about 20% of total land and over 30% of the net cultivable area of Bangladesh [2]. Salinity affected around 53% of coastal soils of the country [1], however, soil salinity fluctuates with seasons in this area. Rice (Oryza sativa L.) is the main crop in the coastal zone cultivated mainly rain fed during the monsoon when soil salinity is lowered.…”

Relationship between Soil Salinity and Physico-chemical Properties of Paddy Field Soils of Jhilwanja Union, Cox’s Bazar, Bangladesh

“…Salt-affected soils are identified by excessive levels of water-soluble salts, especially sodium chloride (NaCl) (Tanji, 2002). Salinity is causing decline in soil productivity and crop yield which results in severe degradation of bio-environment and ecology (Hoque, Saika, Sarder, & Biswas, 2013) as well as responsible for low cropping intensity in coastal area (Rahman & Ahsan, 2001).…”
