Maintaining soil quality for agricultural production is a critical challenge, especially in the tropics. Due to the focus on environmental performance and the provision of soil ecosystem services, organic farming and agroforestry systems are proposed as alternative options to conventional monoculture farming. Soil processes underlying ecosystem services are strongly mediated by microbes; thus, increased understanding...Read More

Agroforestry systems are perceived as an effective approach to store carbon in agroecosystems by building tree biomass and raising soil organic carbon (SOC) stocks. This is especially evident in the tropics, where the cultivation of cash crops such as cacao in agroforestry systems is increasingly used. Among agroforestry systems, organic management, which avoids synthetic inputs...Read More

Cacao in agroforestry systems can benefit from improved nutrient cycling, since shade trees could transfer nutrients through litterfall and pruning residues. Additionally, shade trees could affect decomposition processes of these residues. Studies on nutrient release from pruning residues and on the effect of shade trees on decomposition processes are scarce. We aimed to determine how...Read More

Cacao production is facing challenges of low productivity due to low soil fertility and climate change. Agroforestry and organic farming are potential sustainable and climate-resilient alternatives, but they are often associated with lower yields compared to monocultures and conventional farming. Despite their potential, empirical data on the long-term productivity of cacao cultivated in complex agroforestry...Read More

Cacao Nacional Boliviano (CNB), the native cacao germplasm group in the Bolivian Amazon region, possesses distinct morphological, genetic, phenological and organoleptic characteristics. It is highly sought after in the global fine-flavour chocolate market, and has importance for conservation of cacao genetic diversity. However, CNB cultivation is minor and yield levels low. Aiming to develop profitable...Read More

Light access is the primary factor affecting yields in cacao-based agroforestry systems (CAFS). While CAFS ecosystem services provision is extensively documented, research on improving light access in CAFS remains scarce. Shade canopy pruning, a developing technique in Latin America, is part of the long-term SysCom Bolivia trial. It is undertaken twice a year, at the...Read More

A recent study by Armengot et al. compared four cocoa production systems: agroforestry and monocultures, both under organic and conventional management, over the first five years after establishment. While monocultures produced 41% higher cocoa yields, agroforestry systems generated significantly higher total revenues due to the sale of by-crops like bananas and plantains. Importantly, the return...Read More

A recent study by Orozco-Aguilar et al. highlights the contributions of the CacaoFIT network—a collaborative effort among agronomists, researchers, and practitioners—to sustainable cocoa farming in Latin America and the Caribbean. By assembling data from 25 experimental field trials across diverse agroecosystems, the network explores various cacao cultivation models suitable for smallholder farmers. Key findings indicate...Read More

This study finds that using locally-selected cocoa clones can significantly boost cocoa yields. Conducted over five years in Bolivia, the research compared the performance of local clones against widely-used international varieties and found that local clones produced two to five times more cocoa beans. These clones also had larger pods and therefore required fewer pods...Read More
