About 80 000 to 120 000 species of fungi have been described to date, although the total number of species is estimated at around 1.5 million (Hawksworth, 2001; Kirk et al., 2001).
This would render fungi one of the least-explored biodiversity resources on our planet.
It is notoriously difficult to delimit fungi as a group against other eukaryotes, and debates over the inclusion or exclusion of certain groups have been going on for well over a century.

Improvement of village chicken production: Strategic role of livestock in Sahelian traditional livelihood systems
The role of livestock in developing countries in general and in Sahelian regions, in particular, is already well reviewed by many authors (Ayantunde, 1998; Nianogo and Somda, 1999; Guèye, 2000; Slingerland, 2000). In Sahelian countries animal production is after crop production, the second activity of the population. The level of industrialisation is low and employment in the modern sector (public services and private business) is practically negligible (Slingerland, 2000). About 65 to 80% of the human population live in rural areas and their life is strongly linked to crop and livestock production.
