Aqua-geoponics in Bangladesh

Why "aqua-geoponics"?

  • aqua = pond water
  • geo = mud/soil
  • ponics = cultivation

Our Practical Answers team in Bangladesh is piloting an innovative concept of raising fish in cages and growing vegetables - at the same time.

This farming technique uses water from aquaculture to grow crops or vegetables while it purifies water for fish in the cage or pond. In return, the waste produced by farmed fish supplies nutrients for the vegetables.

This draws on many years of experience that Practical Action has had in promoting "cage aquaculture" - the farming of fish in cages - that has proved a good solution to poor land security in flood-prone areas.

In June 2016 we signed a contract agreement with Blue Gold Programme of the Netherlands Government for piloting this “Cage Aqua-geoponics System in Polder”. We will be working with Bangladesh Agricultural University and Shushilan, a local organisation based in Satkhira district.
