The population of Bargny, a small locality which belongs to the urban nucleus of Diamniadio, lives essentially from fishing and seasonal agriculture.

The programmed growth of the city of Dakar seems to condemn it to disappear. The highway that crosses it, in addition to the main road, has occupied areas of orchards. The new town of Diamniadio has taken away part of its fields and its water tanks for livestock. Due to the passage of the TER roads, many families have been expropriated. Other infrastructure projects further affect the territory of the municipality and its inhabitants, such as the Bargny coal-fired power station or the SOCOCIM cement factory. The latter, built in front of the sea, is located on a plot of land occupied by women who work in fish handling. The smoke and gas emissions from the plant and the cement factory are deposited on the fish products, thus putting at risk the work of the thousand women who work on the beach.
