Typology of coffee-based agroforestry systems in the semi-deciduous forest zone of Togo (West Africa)

Abstract

This study contributes to the knowledge of the variants of coffee-based agroforestry systems (CAFS) of the semi-deciduous forest zone of Togo. To achieve this, forest, floristic and ecological data were collected in 163 random plots of 25 m × 25 m (625 m²), to analyze the typology of the CAFS and their characteristics across the study area. In the 10.1875 ha surveyed, results showed a total of 2510 stems of woody plants belonging to 138 species and 38 families. The average tree density was 246.38 trees/ha, whereas the basal area was 27.99 m²/ha. Four types of CAFS have been identified; the first type (G1) is the plant communities dominated by Milicia excelsa and Persa americana associated with coffee trees; the second type (G2) is characterized by CAFS with Albizia spp. and Citrus sinensis as dominant woody species; the third group (G3) is composed of communities dominated by Albizia adianthifolia and Milicia excelsa and the fourth group (G4) consists of CAFS dominated by M. excelsa and Antiaris africana. The floristic composition showed that the latter CAFS (G4) dominated by M. excelsa and A. africana was the most diversified, more rich in term of species (Species richness = 110, Shannon index = 4.06) and of which the basal area (Basal area = 34.32 m 2 /ha) is larger than the others.

KARAKTERISASI DAN POTENSI BAKTERI ENDOFIT AKAR KOPI (Coffea sp) SEBAGAI PENGHASIL INDOLE ACETIC ACID (IAA)

“…Kopi yang ditanam di Kawasan agroforestri bersamaan dengan jenis tanaman yang tinggi (Pohon). Sistem agroforestry adalah sistem pertanian yang menarik dan menjadi pilihan yang efektif untuk mengurangi hilangnya hutan, untukmelestarikan keanekaragaman hayati dan menyediakan hal-hal penting seperti sumber pendapatan bagi penduduk local (Donko et al, 2019;Jimenez-Soto, 2021).…”

Plant Biodiversity and Structure of Robusta Coffee (<i>Coffea canephora</i> var. <i>robusta</i>) Agroforests in Cameroon

“…RCAs are characterized by the integration or conservation of trees in perennial crop systems like coffee (Temgoua et al, 2020). Coffee trees are traditionally grown in association by most farmers who conserve or introduce some useful plant species in their plantations (Lopez-Gomez et al, 2008;Denu et al, 2016;Koda et al, 2019).…”
