Getting a widespread understanding of the agricultural and economic value of nitrogen-fixing plants is still a struggle in most countries of the South. In November 2004, during the 11th conference of l Association africaine pour la fixation biologique de l azote (AABNF), an African association dedicated to promoting nitrogen-fixing plants, a dance troupe staged a show to demonstrate how a plant that captures nitrogen from the air can use it to benefit neighbouring plants, which only draw nitrogen from the soil. Haricot beans, cowpeas, soya beans and acacias all belong to this group of leguminous plants which can harness nitrogen present in the atmosphere thanks to bacteria living in their root nodules. Increasing their cultivation would help boost vegetable production on poor soils and contribute to the regeneration of degraded environments. A further plus is the high nutritional content of nitrogen-fixing plants, which are extremely rich in protein.
