How long have you / your team been working on this Vision?

  • Under 1 year

Lead Applicant: In what city or town are you located?


Lead Applicant: In what country are you located?


Your Selected Place: what’s the name of the Place you’re developing a Vision for?

Nigeria a land size of 923723km^2.

What country is your selected Place located in?


Describe your relationship to the place you’ve selected.

Reside in Nigeria and I have a first hand knowledge of the average Renewable Energy and  Nutritional status and classification in the region.

 The renewable Energy market has been on the rise in recent although due to the low economic state of the average citizen has not been proactively predominant.

  In terms of Nutrition, alternate means is  rather a solution to Nutritional crisis that wallows the larger population of the urban and distressed region. The introduction of Spirulina would be an accurate one for the market and region based on the defined terms.

Describe the People and Place: Provide information that would be helpful for an outsider who has never been there and may have no context about this Place to better understand the area.

Nigeria has been home to a number of ancient and indigenous kingdoms and states over the millennia. The modern state originated from British colonial rule beginning in the 19th century, and took its present territorial shape with the merging of the Southern Nigeria Protectorate and Northern Nigeria Protectorate in 1914. 

Nigeria is often referred to as the "Giant of Africa", owing to its large population and economy.With 206 million inhabitants, Nigeria is the most populous country in Africa and the seventh most populous country in the world. Nigeria has the third-largest youth population in the world, 

Nigerian cuisine, like West African cuisine in general, is known for its richness and variety. Many different spices, herbs and flavourings are used in conjunction with palm oil or groundnut oil to create deeply flavoured sauces and soups often made very hot with chili peppers. Nigerian feasts are colourful and lavish, while aromatic market and roadside snacks cooked on barbecues or fried in oil are plentiful and varieties

What is the approximate size of your Place, in square kilometers? (New question, not required)


What is the estimated population (current 2020) in your Place?


Challenges: Describe the current (2020) and the future (2050) challenges that your food system faces.

The world’s population is increasing rapidly, and there is a need to identify new food and feed resources. One possibility to meet the need for high-quality protein is through increased production of the microorganism known as Spirulina. The current system has a deficit in food supply both in diversity and neccesities. The 2050 challenges can only be buffered if the following are considered 

1) Environment; The production of Spirulina from effluent or any other means is considered one of the most environmental friendly food production as there are no carbon emissions and also there are little or no harazdous chemical disposed to the environment

 2)Culture; The addition of Spirulina to Nutrition patterns would not really affect the Culture of the people as the food could be added to other traditional meal and be consumed without changing traditional meals but rather making the traditional meals better as an improvement. 

3) Technology; The technology intended to be used in production is a system where effluent from biogas digesters would be automatically analysed and sterilized and then if they meet the Nutrients feed requirement for Spirulina would be feed into a closed automated Spirulina systems which would be portioned in volume quantification and automatically harvested. With specific monitoring features to check the food standard and quality the automated system with a good monitoring system ensures safe and quality Spirulina. 

4)Diets; The algea food could be consumed in drinks, made with other cereal and different foods, added to pastry and confectionery product and furthermore to an endless array of foods in people's diet 

5)Economics; The cost of the product in comparison to it's Nutritional provision and food use flexibility could be considered quite economical with continous research and more commercial Production it definitely becomes a considerable low price high Nutrition product 

6)Policy; At the moment almost all policies governing the food industry in West Africa favours the production provided the product meets the food standard and quality required for safe consumption.

Address the Challenges: Describe how your Vision will address the challenges described in the previous question.

Most of the challenges stated where explained with their possible actions for advancement But it be specific they include

1) Environment - The vision would tackle environmental problems by encourage the use of waste for production rather than polluting water bodies or indiscrimate disposal

2) Culture - The solution is an easy inclusive one which would allow accommodation into the current culture trend. For example the powder can be easily added to other flour and would not change the food type but rather improve it's Nutritional status.

3) Technology - The vision address the use of technology by creating new avenues like inclusion of a closed cultivation system which would help improve more aspectic culture cultivation techniques 

4) Diet - The vision would directly improve the diet by creating new meals and providing more consumption options for the defined population

5) Economics - The vision would provide a relatively economical Nutritional intake product compare to the value from other sources. It would also be an economic alternative or rather one of the most economical disaster relief Nutritional material

6) Policy - The guiding policies that governs the production of the Nutritional material that the vision profounds would be constantly improved as the vision improves it's activities in defined areas. 

High Level Vision: With these challenges addressed, now provide a high level description of how the Place and the lives of its People will be different than they are now.

 The effect on Nutrition on a society can never be underrated. A society with proper Nutrition reflects to a society with proper development. 

  All developed countries have a balance Nutritional be society and  With the additional of Spirulina and increase in Nutritional intake in Nigeria one can assure that there would be a rapid transit from underdeveloped to developing and then developed region which directly translate to economical development, Prosperity and advancement.

Full Vision: How do you describe your Vision for a regenerative and nourishing food future for your Place and People for 2050?

The approach would be environmental friendly. A key benefit of spirulina is its high protein content. While accessing good quality protein is not hard for those who live in the west, the same cannot be said for those living in poverty in developing countries.

 On paper in terms of food security in the context of a growing demand for protein,it is calculated that the algae (along with ‘in vitro’ meat) has the lowest land use per unit of protein and unit of human digestible energy. In other words, it offers the potential to improve food security while also benefitting the environment by requiring less land to produce the same amount of protein and energy as livestock. Spirulina is among the world’s most popular supplements It is loaded with various nutrients and antioxidants that may benefit your body and brain.  

      Spirulina Is Extremely High in Many Nutrients Spirulina is an organism that grows in both fresh and salt water. It is a type of cyanobacteria, which is a family of single-celled microbes that are often referred to as blue-green algae. Just like plants, cyanobacteria can produce energy from sunlight via a process called photosynthesis. Spirulina was consumed by the ancient Aztecs but became popular again when NASA proposed that it could be grown in space for use by astronauts . A standard daily dose of spirulina is 1–3 grams, but doses of up to 10 grams per day have been used effectively. This tiny alga is packed with nutrients. A single tablespoon (7 grams) of dried spirulina powder contains : Protein: 4 grams Vitamin B1 (thiamine): 11% of the RDA Vitamin B2 (riboflavin): 15% of the RDA Vitamin B3 (niacin): 4% of the RDA Copper: 21% of the RDA Iron: 11% of the RDA It also contains decent amounts of magnesium, potassium and manganese and small amounts of almost every other nutrient that you need. In addition, the same amount holds only 20 calories and 1.7 grams of digestible carbs. Gram for gram, spirulina may be the single most nutritious food on the planet. A tablespoon (7 grams) of spirulina provides a small amount of fat — around 1 gram — including both omega-6 and omega-3 fatty acids in an approximately 1.5–1.0 ratio. The quality of the protein in spirulina is considered excellent — comparable to eggs. It gives all the essential amino acids that you need. It is often claimed that spirulina contains vitamin B12, but this is false. It has pseudovitamin B12, which has not been shown to be effective in humans. The technology would include an automated effulent sterilezer and infusser and would then be forwarded to the main system which uses a micro-controller with a couple factors included,However, the technical and financial limitations, stable mass production of microalgae are not easy tasks to solve. 

 Precise control over the environmental conditions in the place where microalgae grow and timely supply of the necessary materials would be the most prerequisite requirements for the stable growth of the microalgae. This requirement might be sufficed by mass cultivation and automated microcontroller system. In this Solution a microcontroller system of microalgae culture would be introduced with an Arduino. This microcontroller platform would be applied for more effective culturing method, monitoring the multiple environmental conditions: temperature, light, carbon dioxide and monitoring pH change. The result should demonstrate that the algae concentration from the microcontroller group is 16.5% on average which should be greater when compared to that from the algae group cultured in natural indoor conditions after 35 days of cultivation. The microcontroller system might be applied with more elaboration in the algae culturing technologies.

  The dieting and cultural integration could be said to be an easy pass for spirulina, although it has not really been a constant part of both there have been easy acceptance in introductory region and the evidence of the inherent owners ( residence of lake chad region) has made it even more obvious.

  All fingers in terms of policy definitions are well directed towards a positive acceptance and accomodations of Spirulina.
