The paper "Marine Shrimp Farming in Bangladesh" is a perfect example of a case study on agriculture. Marine shrimp cultivation entails shrimp production in an enclosed or controlled water body. There can be the use of both fresh and saline water. Shrimp is among the leading products of export in Bangladesh and is the second export earner, contributing greatly to the economy of Bangladesh. Among the countries producing shrimp, Bangladesh is number four regarding shrimp farming area and number six in production volume. 97% of the shrimp produced in the country is exported, and this contributes to four percent of the country's GDP.
The sector also employs approximately 1.2 million people. Approximately 300,000 shrimp farmers from Bangladesh produce approximately 170,000 tons of shrimp each year. Bangladesh's global market segment for shrimp is about 2.5%. The country is number 12 regarding cultured producer of shrimp. The major destinations of Bangladesh shrimp are the USA (26%), Russia (3%), Belgium (21%), Germany (8%), Netherlands (5%), Japan (4%) and others (21%) (Rahman 1). Although there are numerous benefits associated with shrimp farming, it has led to the destruction of the mangrove forest.
It was until 1989 when the Bangladesh government banned the destruction of the mangrove forest through fishing. The earthen ponds used for shrimp farming are created from seawater and freshwater. Creating these ponds means that there is the conversion of native habitats, for example, mangrove forests, and traditional land for agriculture, as well as salt marshes. There is also the alternation of the power dynamics of the community as well as a change in the use of the land. There is also the undermining of the social stability whereby there are cases where those opposing this kind of farming are subjected to harsh treatment including rape.
Apart from that, there is a reduction in the capacity for the production of food locally since most of the local resources are geared towards the production of shrimp products. There is also the destruction of the ecosystem provided by the native habitats. The high concentration of salt has led to a reduction in denitrifying microorganisms and has affected the ammonifiers. There is a variation of acetobacter population depending on the salt concentration.
When there is an increase in water's solute concentration, there is the commencement of cellular dehydration meaning that the microorganism will die. Apart from that, there is an increase in the fungi number with an increase in the saline level. There are cases where shrimp farmers have ended u killing animals thinking that they can harm shrimp (Barbier, Edward, & Suthawan 5). Expression of a likely Viewpoint from a Local Village Elder Shrimp farming has led to the release of saline water, and this has made the traditional agriculture difficult.
In most cases, shrimp farming is unplanned, and this has affected the agriculture yields, soil, biodiversity, ecology, and sustainability especially in the coastal parts of Bangladesh. There are also adverse health effects of shrimp farming and this mainly affected the poor farmers. Many farmers have also abandoned rice farming. There has also been a reduction in crop production mainly because there is the high salt content in the soil's root zone. There is also an increase in the salinity of the groundwater and this makes the water not suitable for irrigation.
There is also the depletion of nutrients from the soil, and this is mainly because of the soil salinity. The quality of the soil has also been degraded. Apart from that, there has been an adverse effect on the local vegetation, livestock, environment, population health, population health, as well as disease patterns. Apart from that, more land has been used for shrimp farming leading to deforestation, and this affects the overall climate of the area (Jahan & Hasneen 54).
