Kevin Barber is building a               aquaponics sytem in his family compound. But notoriously rugged               make transporting fish harder.
To manage our aquaponics system, they share or               the things that we need.
Once the fish are part of the system, the               process can begin. The treated waste from a dunk tank will changed into nutrient-rich               for plants in growbeds. Then the               water is directed into two ponds; One with the fish and another with duckweed.
It doesn’t look too              , though and these ponds ultimately create
an               of food production.

The final piece of the puzzle is               the sun’s rays to empower the whole system. In a rural area in Costa Rica, blackouts are common              , so Barbers rely on a gas-driven generator.
In case of economic crisis, fuel for the generator could be insufficient, so solar energy is the most reliable substitute to set up the system. Off grid               are used to run the aquaponics pump so that the pump can run at               or
on               days.
