Ethnicity, land use and woody vegetation: a case study from south-western Burkina Faso

Ethnicity, land use and woody vegetation: a case study from south-western Burkina Faso Woody vegetation in cultivated landscapes in Burkina Faso is influenced by agricultural activities that are in turn influenced by institutional arrangements. Research was undertaken in a village in south-west Burkina Faso to investigate the relationship between species composition, diversity, density, species accumulation and land use category. Additionally the relationship between number of trees, size of farmed land and farmer ethnicity was investigated. Indigenous Tiéfo farmers had on average more than double the number of large (>4 m) trees of Vitellaria paradoxa Gaertn. f., Parkia biglobosa (Jacq.) R. Br. Ex G.

Botanical inventories of fallows more than 4 years old, cultivated parklands and plantations of Mangifera indica L. and A. occidentale showed that tree density and Simpson’s index of diversity for trees were highest in the fallow.

The average regeneration density was 12,605, 1,995 and 6,772 seedlings ha -1 for fallow, parklands and plantations, respectively.

Abstract

Woody vegetation in cultivated landscapes in Burkina Faso is influenced by agricultural activities that are in turn influenced by institutional arrangements. Research was undertaken in a village in south-west Burkina Faso to investigate the relationship between species composition, diversity, density, species accumulation and land use category. Additionally the relationship between number of trees, size of farmed land and farmer ethnicity was investigated. Indigenous Tiéfo farmers had on average more than double the number of large (>4 m) trees of Vitellaria paradoxa Gaertn. f., Parkia biglobosa (Jacq.) R. Br. Ex G. Don and Anacardium occidentale L. than farmers belonging to other ethnic groups, but this was partly explained by a larger area being available. Differences between ethnic groups were not significant when expressed per ha. Botanical inventories of fallows more than 4 years old, cultivated parklands and plantations of Mangifera indica L. and A. occidentale showed that tree density and Simpson’s index of diversity for trees were highest in the fallow. Simpson’s index was not significantly different for regeneration, but sample-based species accumulation curves indicated that species accumulation in parklands was faster than in plantations when expressed per individual. The average regeneration density was 12,605, 1,995 and 6,772 seedlings ha -1 for fallow, parklands and plantations, respectively. This low density for parklands means that species accumulation is slow compared to the other land uses when expressed per unit area. Fallow seems the most efficient way of keeping tree diversity in the agricultural landscape.
