“…Indeed, from the root of nine species often used in the CAFS in Ghana was isolated P. megakarya ( Akrofi et al, 2015 ). These species are reported in the floristic composition of AFS with cacao from Africa ( Sonwa et al, 2007 ) and are widely used in agroforestry systems in American countries, such as Musa paradisiaca, Persea americana, Mangifera indica and Carica papaya ( Ramírez-Meneses et al, 2013 ; Guiracocha et al, 2016 ; Peña et al, 2019 ; Mercedes Ordoñez and Rangel-Ch, 2020 ; Jaimes et al, 2021 ). Other species frequently used in this system in Africa are also reported as hosts of P. megakarya and P. palmivora , among which we can find forest and palm species such as Irvingia gabonensis , Funtumia elastica , Sterculia tragacanta, Ricinodendron heudelotii, and Elaeis guinnensis ; shrubs and short plants such as Dracaena mannii, Xanthosoma saggitifolium, Colocasia esculenta, Athyrium nipponicum and Ananas comosus ( Opoku et al, 2002 ; Holmes et al, 2003 ; Akrofi et al, 2015 ).…”

Low technological knowledge in production chains, global climate change, and misinformation are concrete threats to food security. In addition, these combined threats also trigger ecological instability in megadiverse areas of the world, especially in some cacao-producing countries in South America, where this crop plays an important socio-economic role, even being used to replace illicit crops. Accordingly, the use of agroforestry systems approaches has emerged as a good alternative to maintain productivity, add high-value commodities to producers, and provide important ecosystem services for sustainable agriculture. However, limitations associated with the competition for resources between the species composing the system, and the higher incidence of some diseases, have led many producers to abandon this strategy, opting for monoculture. In this review, we seek to gather the main information available in the literature, aiming to answer the question: what is the real scientific evidence that supports the benefits and harms of adopting agroforestry systems in cacao production? We seek to make critical scrutiny of the possible negative effects of certain associations of the agroforestry system with biotic and abiotic stress in cacao. Here, we review the possible competition for light and nutrients and discuss the main characteristics to be sought in cacao genotypes to optimize these inter-specific relationships. In addition, we review the research advances that show the behavior of the main cacao diseases (Witch’s broom disease, frosty pod rot, black pod rot) in models of agroforestry systems contrasted with monoculture, as well as the optimization of agronomic practices to reduce some of these stresses. This compendium, therefore, sheds light on a major gap in establishing truly sustainable agriculture, which has been treated much more from the perspective of negative stigma than from the real technological advantages that can be combined to the benefit of a balanced ecosystem with generating income for farmers.

“…Currently, agroforestry presents multiple opportunities to improve ecosystem services to people and communities and, at the same time, decrease pressure on the environment (Braga et al, 2019;Manaye et al, 2021). Integrating woody and non-woody species, such as fruit, is commonly employed by smallholders to diversify land use in agroforestry systems (AFS) (Mercedes and Rangel-Ch., 2020). Trees play a fundamental role in agroforestry production and farmers' livelihoods in Latin América, as they provide a wide range of ecosystem services, which are essential for maintaining the health and productivity of agricultural and forestry systems and improving the resilience and adaptation of rural communities to the impacts of climate change (Morán-Villa et al, 2022;Ramos-Prado et al, 2023).…”

Timber production in agroforestry systems can improve environmental and economic sustainability, especially for families living in rural areas. Despite its importance in Guatemala, little is known about the potential of wood and its contribution to the sustainability of traditional agroforestry systems. This study aims to analyze the timber resources in cocoa agroforestry systems (CAFS) of different ages, evaluating variables such as floristic composition, species diversity, and the potential to obtain timber from the species present in the evaluated CAFS. Twenty temporary sampling plots of 2,500 m2 were established, and dendrometric variables were measured in all plots. Species occurrence was statistically analyzed by cross-tabulation and Pearson's Chi-square test (χ2) to determine species' frequency distribution among the evaluated CAFS ages. Eight hundred twenty-seven trees of 38 species belonging to 19 families were identified. The most represented species in the age range of the evaluated CAFS were Gliricidia sepium (35.07 %), Swietenia macrophylla (19.11 %), and Inga sapindoides (7.62 %). The total shade trees occupied a basal area of 33.29 m2, and a total volume of 352.35 m3 was recorded, of which 148.9 m3 were for commercial use. The most frequent uses of the wood were firewood (38.21 %), thin plank (30.23 %), and poles (22.85 %), while the use of thick plank was the least common (8.71 %). The CAFS in the studied area are characterized by a wide diversity of shade tree species. These results provide a solid basis for promoting sustainable practices that foster the productivity and preservation of these systems, thus contributing to the sustainability and well-being of farmers.

Trees in cacao Agroforestry systems (AFS) may present a high potential for cadmium (Cd) phytoextraction, helping to reduce Cd in cacao (Theobroma cacao L.) plants grown in contaminated soils. To assess this potential, four forest fine-woody species commonly found in cacao high-productive sites in Colombia (Tabebuia rosea, Terminalia superba, Albizia guachapele, and Cariniana pyriformis) were exposed to contrasting CdCl2 contamination levels (0, 6, and 12 ppm) on a hydroponic medium. Growth dynamics, tolerance index (TI), and Cd concentration and allocation in leaves, stems, and roots were evaluated for up to 90 days after initial exposure. T. superba, A. guachapele, and C. pyriformis were classified as moderately tolerant (TI > 0.6), and T. rosea was considered a sensitive species (TI < 0.35) under 12 ppm Cd contamination. Despite showing a high stem Cd concentration, C. pyriformis also showed the lowest relative growth rate. Among the evaluated forest species, A. guachapele exhibited the highest Cd accumulation capacity per plant (2.02 mg plant−1) but also exhibited a higher Cd allocation to leaves (4%) and a strong decrease in leaf and stem dry mass after 90 days of exposure (~75% and 50% respectively, compared to control treatments). Taking together all the favorable features exhibited by T. superba as compared to other CAFS tree species and recognized phytoextractor tree species in the literature, such as Cd hyperaccumulation, high tolerance index, low Cd concentration in leaves, and high Cd allocation to the stem (harvestable as wood), this species is considered to have a high potential for cadmium phytoextraction in cocoa agroforestry systems.
