Adaptive capacities such as aquaponics need to
be developed to mitigate these impacts. Aquaponics is a bio-integrated system
that links recirculating aquaculture with hydroponics vegetable, flower, and/or
herb production with the potential to address the aforementioned issues. There
is a growing need for successful inland intensive/semi-intensive aquaculture systems
driven by production technology that is energy and space efficient such as
recirculating aquaponics with minimal or zero discharge waste as it remediates
water for re-use. Therefore, there is a need to create sustainable systems that
are economically, socially and ecologically sustainable as a farming practice
to produce nutritious and healthy fish, as well as organic grown vegetables
through minimal and sustainable use of available resources. The systems need to be suitable for rural and
urban use, creating informal markets and food security through supply of local
fresh produce, with economic benefits such as job creation, monetary benefits,
and gross domestic product (GDP) increase.
Aquaponics is a promising method of sustainable food
security and food sovereignty, where production can take place in impractical
places for normal in urban and peri-urban areas such as flat roofs, development
sites, abandoned factories, schools, housing estates and underutilized areas.
Urban communities can have fresh and high-quality food (plants and fish)
produced locally instead of being transported over long distances relying on
high carbon dioxide (CO2) foot-prints of fuel fossils. Aquaponics
improves access to affordable and diverse food at the same systems that can
possibly be up-scaled to transform subsistence farmers into small/medium-scale
commercial farmers to generate livelihoods.
