|Abstract: ||The promotion of cacao agroforestry is one of the ways of diversifying farmer income and creating
incentives through their inclusion in REDD+ interventions. We estimated the aboveground carbon stocks in
cacao and shade trees, determined the floristic diversity of shade trees and explored the possibility of implementing
REDD+ interventions in cacao landscapes. Using replicated multi-site transect approach, data were collected from
nine 1-ha plots established on 5 km long transects in ten cacao growing districts in Ghana West Africa. Biomass of
cacao and shade trees was determined using allometric equations.
One thousand four hundred and one (1401) shade trees comprising 109 species from 33 families were
recorded. Total number of species ranged from 34 to 49. Newbouldia laevis (Bignoniacea) was the most frequently
occurring specie and constituted 43.2 % of all shade trees. The most predominant families were Sterculiaceae and
Moraceae (10 species each), followed by Meliaceae and Mimosaceae (8 species each) and Caesalpiniacaea (6 species).
Shannon diversity indices (H’, Hmax and J’) and species richness were low compared to other similar studies.
Shade tree densities ranged from 16.2 ± 3.0 to 22.8 ± 1.7 stems ha−1 and differed significantly between sites. Carbon
stocks of shade trees differed between sites but were similar in cacao trees. The average C stock in cacao trees was
7.45 ± 0.41 Mg C ha−1 compared with 8.32 ± 1.15 Mg C ha−1 in the shade trees.
Cacao landscapes in Ghana have the potential of contributing to forest carbon stocks enhancement by
increasing the stocking density of shade trees to recommended levels.|
