How did the idea of developing this project start ?

We couldn't bear to see children dying from malnutrition.

The climate of Benin is favourable to agriculture, with alternating dry and wet seasons. Wide areas are covered in savannah which allows traditional cereals such as millet, manioc, yam and corn to be grown. You can also find fruits such as mangoes, papayas, bananas and oranges. However, traditional foods lack protein: meat and fish are expensive, and are only eaten on special occasions. Although children are breast-fed, and then fed on corn, and  yam flour, they often arrive  too late at the clinic, with swollen stomachs and a loss of skin pigmentation.

They have to go through a nutritional recovery or transfusion at the hospital in NIKKI (32Km away) and sometimes it's too late.

  A type of food suitable for all ages, and quickly efficient, needed to be found. In this clinic, SPIRULINA has proved itself highly efficient when mixed with porridge enriched with vitamins.

Spirulina is a micro-algae that grows naturally in lakes in Chad or Mexico. It contains 60% to 70%  proteins, vitamins A, B1 to B12, beta-carotene, magnesium and  iron. It strengthens the body's immune defences, and it is very efficient against malnutrition.

The conditions for a good crop are "heat and sunshine", which Benin doesn't lack. It yields around 5g dry spirulina per m² per day. We can therefore produce 400 g a day with our four 20 m² ponds.
  5g a day during 1.5 month is enough to save a child from malnutrition.

Evolution of the project :

After visiting an « algae farm » at the Sainte Camille's clinic in DAVOUGON, Benin, we decided together with sister Maria-Luisa, the Head Nun of Péréré, that the project was feasible. We also visited Pahou which is the biggest algae farm in Benin at the moment.
bassins à PahouPonds for the cultivation of Spirulina, in Pahou (next to Cotonou) south Benin.
spiruline au microscopeSpirulina owes its name to the spiral shape of its filaments. They get longer and divide themselves under the action of heat and light, feeding on the growth medium.
spiruline fraicheSpirulina can be eaten fresh, spread on bread and why not with a glass of "rosé" wine like here, in the training centre in Hyères.
After reading several books about the subject, we went on a specific training course called: « Formation à la production de la spiruline à vocation humanitaire » (training in the production of spirulina for Humanitarian Purposes): (see Jean-Paul Jourdan' blog). We were trained by dedicated teachers who are experts in their field. It helped strengthen our motivation and we started  building the first ponds in Péréré early in January 2008. We built two ponds of about 20 m² each on land generousely lent to us by the Italian nuns. We got the support and advice of the "algae-farmer" from PAHOU , near Cotonou, the first centre in Benin where the SPIRULINA was grown.
 Our strain (named "LONARD") comes from this centre, and we got together with Davougon in order to ship the inputs that feed our micro-algae.
In 2009, we built 2 more ponds, increasing the production area to 80 m².

Four ponds of about 20 m² each are now in use. The average daily crop ranges from 2.4 to 3 kg of fresh Spirulina. We are considering building other ponds, to make the algae-farm profitable and therefore sustainable.
The greenish liquid from the pond is filtered through canvas, which is normally used in silk-screen printing. The harvested Spirulina is drained and pressed before being transformed into "spaghetti",  and laid on a shelf.
It then dries in a solar oven for 4 hours. After being crushed into flakes, the Spirulina is weighed, put in vacuum bags and labelled, ready to be sold...but it will often be given free to those who really need it.
spiruleThe ball of Spirulina is introduced into the sausage maker. We modified the nozzle by making a line of small holes. The elements in contact with Spirulina and the liquid from the ponds must be made of stainless steel or plastic, and hygiene is strict..
We try to train as many people as we can in the cultivation of Spirulina, to ensure the continuity of the algae-farm.
The building of the premises started in December 2007, The ponds were set up in January and February 2008.
The first crop took place on 1st March 2008.
The solar dryer was build in October 2008 and on the 21st Octobre 2008, we sealed up our first bag of dried spirulina.
