Agroforestry parklands face strong pressure from the increasing population of the region. The World Agroforestry Centre (ICRAF Sahel) started a biodiversity project with the objective of developing methods to conserve biodiversity and to improve the situation of the poor rural population. In this context the present study examined the influence of land use unit and the prosperity classes of farmers on the biodiversity of woody species. A wealth ranking classification was carried out and applied to the households of two villages in the central plateau of Burkina Faso using the "Participatory Analysis of Poverty and Livelihood Dynamics" (PAPoLD) method. Thirty farmers of different prosperity classes were chosen and inventories carried out on their different land use units. Statistical analyses show an increase in biodiversity from the village housings. However, no significant influence on biodiversity was observed in connection with a farmer's prosperity class.

Objectif : L’objectif de cette étude est d’identifier les espèces utilisées comme bois d’énergie pendant la cuisson de la bière locale et la transformation des amandes de karité en beurre, d’apprécier les niveaux exploitation de ces espèces et de cerner les raisons des préférences d’utilisation de ces espèces. Méthodologie et résultats : Une enquête a été conduite auprès des femmes productrices pour connaître les espèces utilisées prioritairement comme bois énergie. Une estimation du pouvoir calorique des espèces les plus utilisées a été faite au laboratoire. Dix-neuf (19) espèces ligneuses appartenant à onze (11) familles ont été citées comme entrant dans la cuisson de la bière locale et du beurre de karité. Le bois de ces espèces a montré un pouvoir calorifique plus élevé, justifiant les préférences des femmes pour celles-ci. Cependant, la disponibilité des espèces dans les villages reste déterminante pour le choix de leur utilisation. Conclusion et application des résultats : La connaissance des préférences des espèces prioritaires utilisées comme source d’énergie par les femmes constitue une information cruciale pour le choix des espèces à produire pour la restauration du couvert végétal des terroirs villageois. Aussi, la présente étude recommandet-elle ces essences préférées des femmes pour la cuisson de la bière locale et du beurre de karité comme espèces ligneuses à produire par les pépiniéristes pour les campagnes de plantation d’arbres dans les terroirs villageois Mots clés : bois-énergie, pouvoir calorifique, bière locale, beurre de karité, Burkina Faso ABSTRACT Objective: The objective of this study is to identify the species used as fuelwood during the cooking of local beer and the processing of shea kernels into butter, to assess the use levels of these species and to identify the reasons for the preferences of these species. Methodology and results: A survey was conducted among women producers to find out the species used mainly as fuelwood. An estimate of the caloric value of the most used species was made in the laboratory. Nineteen (19) woody species belonging to eleven (11) families were cited as being used to cook local beer and shea butter. The wood of these species showed a higher calorific value, justifying the women's Dao et al., J. Appl. Biosci. 2020 Préférences des femmes et pouvoir calorifique d’essences de bois d’énergie utilisées pour la cuisson de la bière locale et du beurre de karité au Burkina Faso 16140 preferences for them. However, the availability of the species in the villages remains a determining factor in the choice of their use. Conclusion and application of results: Knowledge of the preferences of priority species used as energy source by women become crucial information for the choice of species to be produced for the restoration of the vegetation cover of village landscapes. Therefore, the present study recommends these species preferred by women for the cooking of the local bee and the shea butter as woody species to be produced by nurserymen for tree-planting campaigns in the village landscapes. Key words: Fuelwood, calorific value, local beer, shea butter, Burkina Faso

AbstractExtensive tall-trunk orchards, an important element of the central European landscape since the Middle Ages, conserve potential for the future regarding their biodiversity, land use policy and agricultural value. For these reasons, extensive tall-trunk orchards are interesting with regard to nature conservation. Once the management of these low-productivity vegetation sites ceases, the habitat is threatened by successive overgrowth by shrub vegetation. Taking abandoned tall-trunk cherry orchards with dry/mesophilous grassland undergrowth in the locality of Kaňk as an example, the degree of colonization of orchards by woody species and differences in the structure of vegetation cover in different periods after abandonment were monitored. The results showed that the cover of cherry trees in orchards abandoned before 1990 was approximately 30% lower than in orchards abandoned after 2000. The cover of the herb layer in orchards abandoned before 1990 was approximately 60% lower than in orchards abandoned after 2000. The species diversity of orchards abandoned before 1990 was statistically significantly lower than that of orchards abandoned after 2000. The total cover of all species in habitat in areas of medieval ore extraction was approximately 50% lower than that in land originally used for farming.
