Hello my name is Céline. I have experienced a solution to revitalize the soil using aquaponics the last past years in South East Asia. This is a whole model that takes place in 3 stages on a time continuum.
What is it about?
In the short term: Step 1
We set up a small scale (100m2) aquaponics system to multiply the production lines (vegetables, fruits and fish) and multiply the incomes. As a transitional tool, this system allows the soil ecosystems to take the time to regenerate while ensuring food security for everyone. We therefore ensure local food resilience.
In the medium term, Stage 2
Soil microbiology is revived thanks to the aquaponics liquid (innovative). It is a kind of plant probiotype that helps in the revitalization of soil bacteria.
In the long term, Step 3
We combine the methods of the permaculture, agroecology, agroforestry and biodynamics whose regeneration cycles are taking longer.
STEP 1: SO WHAT IS AQUAPONICS ?
It is a soil-less culture that is around 5000 years old. It is native from Mesoamerica and South East Asia. It combines 3 ecosystems: Fish farming, Bacteria culture and Culture of Plants in water that circulates in a closed circuit.
Fish wastes are transformed into nutrients by bacteria. These nutrients circulate into the water and are absorbed by the roots of the plants that filter water.
It is a kind of phyto-purification ... but edible.
In a non-food setting, there are possibilities to clean up rivers by cultivating botanical species adapted to pollution.
STEP 2 : REVIVIFY THE SOIL WITH AQUAPONICS? A PATENT IN PROCESS
Today the soils are degraded, polluted, their fertility is in danger and our food security also according to the IPCC report of 08/09/2019. Scientific studies show that it takes 5 to 10 years to restore these soils. The cycles of regeneration of nature are not set on the cycles of humans. There is therefore a gap between the biological reality of the soil and our desire for food self-sufficiency.
This is where step 2 of the model is innovative! Because I use aquaponics as a remedy to cure soils. The aquaponics liquid revitalizes the dead soils while allowing to quickly produce vegetables, fruits and fish.
The feedback and the solicitation of certain structures led me to file a patent in 2019 in order to channel and preserve the circulation of this know-how in the interest of the Collective. So I refused funding in order to maintain my ethics and intellectual integrity.
Independence is a difficult choice and your donations are precious!
STEP 3 : INTEGRATE PERMACULTURE, AGROECOLOGY, AGROFORESTRY AND BIODYNAMICS
This step is for the long term. Agroecology and permaculture give results from 5 to 7 years of practice and the benefits of the establishment of agroforestry systems are beyond 10 years.
The use of these methods is essential because they are complementary to steps 1 and 2 and constitute the long-term natural regeneration cycles in the integrated system.
If we are now in a desert steppe agriculture, the sustainable agriculture of tomorrow will be around the trees which are the guardians of the water cycle and the structure of fertile soils.
It requires a greenhouse, an aquaponics system, photovoltaic panels, a traditional market gardening area and great motivation !
This project has already been carried out in Vietnam and Burma. It was here at Dieulefit that I started setting up the prototype farm.
The earthwork area will accommodate a BIOCLIMATIC greenhouse of 75m2 in wood and alveolar polycarbonate so that it can keep a temperature above 11 ° c t and welcome the aquaponics system.
Without foundation or concrete we recycled tires to develop the north and south facades
It has a Canadian well for geothermal ventilation.
This recycled tire method stores heat from the sun during the day and then re-diffuses it at night.
The photovoltaic panels will power the submersible and oxygen pumps of the aquaponics system. They will be located at the foot of the greenhouse for more efficient maintenance.
The aquaponics system will produce 400 polyculture plants.
The aquaponics system will be equipped with a 4000L fish tank, swirl filters, bacteriological filters and a culture bed in pipes where 400 plants will grow.
Within the framework of the model, the aquaponics system will serve to ensure local food autonomy while regenerating the 2500m2 of market gardening on living soil of the micro-farm.
Bacteriological soil tests will be carried out over a whole year.
YOUR DONATIONS WILL BE USED TO FINANCE
The idea is that this transient system is also self-sufficient in terms of energy:
1. Photovoltaic panels required to supply electricity to the submersible pump and the oxygen pumps of the aquaponics system without being dependent on nuclear energy. No LED
Quote between € 9,000 and € 13,000 (€ 3 / Watt installed, € 1,000 per m2)
2. Polycarbonate sheets which will be used for the bioclimatic greenhouse
3. Payment for 2 soil microbiology tests at 2 different times (before / after)
Bacteriological analysis of soil or substrate without a priori and Targeted bacterial count on soil or substrate: € 2,150
4. The 9.6% HT required to finance MiiMOSA
