Summary: In agroforestry systems, the abundance, diversity, and richness of butterflies are positively influenced by the richness of shade trees, while negatively affected by the use of chemicals. The high diversity of butterflies indicates resilience of the agroforestry environment, but maintaining and improving ecosystem complexity is still crucial. Organic farming should be promoted to preserve ecosystem services provided by pollinators, especially in the face of increasing intensity in coffee production in Indonesia. Immediate action is needed to prevent the reduction in ecosystem complexity that could threaten the resilience of agroforestry habitats.

Summary: This study identified drivers behind woody plant regeneration in coffee agroforestry, showing that local management intensity negatively impacted species richness, diversity, density, and height, while sites adjacent to continuous forests had higher species richness and diversity. Transfer limitation was detrimental for the regeneration of late successional species in agroforestry systems with reduced woody plant diversity.

Summary: Tree-based ecosystems play a crucial role in climate change mitigation. The study analyzed carbon stock patterns in different land-uses in the Indian Himalayan Region and found that natural forests have the highest biomass carbon stock, while plantation forests have the highest soil organic carbon stock. The relationship between environmental variables and carbon stock was not significant.

Summary: Agroforests in complex landscapes play an important role in biodiversity conservation. The land-use history of agroforests determines their conservation value. Comparisons among multiple baselines can help evaluate the contributions of agroforestry systems to bird conservation at a landscape scale.

Summary: The study demonstrates that participating in the specialty coffee market can increase income for coffee farmers, but with certain conditions. The high prices of specialty coffee can boost forest coffee production and promote forest conservation.

Summary: This study presents a rapid assessment method developed to measure non-cocoa tree characteristics in cocoa fields in Ghana. The results show that certain indicators, such as species richness and shade cover, have lower proportions of fields with recommended levels. The methodological procedure allows for easy updates and replication in different areas, contributing to monitoring biodiversity over time.

Summary: Tropical agroforestry systems play a dual role in providing resources for farmers' livelihoods and serving as refuges for biodiversity. The relationship between yield and biodiversity in these systems is complex, with a potential trade-off between increased yield and biodiversity conservation. Our study in southwestern Ethiopia found a concave relationship between species richness of woody plants and coffee yield, indicating a faster decline in tree richness at lower yields. There was no relationship between coffee yield and species richness of herbaceous plants or bryophytes. The composition of woody plants, herbaceous plants, and bryophytes also showed a concave relationship with coffee yield. These findings highlight the need for multi-year data to assess the biodiversity-yield relationship reliably and suggest opportunities for increasing yields without biodiversity loss along the productivity gradient.

Summary: Agroforestry systems are a promising land use practice for conservation and rural livelihoods. A study in the Western Ghats region of India found that Grevillea robusta remained the dominant tree species in shade coffee farms, but tree density decreased significantly from 2008 to 2017. Basal area increased during this period, with higher tree density in unredeemed coffee farms than redeemed farms. Further research is recommended to understand tree diversity dynamics in a larger coffee-growing region.

Summary: Commercial coffee polyculture fields in Java, Indonesia can sustain levels of bird abundance, diversity, and richness comparable to agroforestry systems under natural forest. These complex systems serve as an alternative refuge for biodiversity and have a higher proportion of nectarivores, insectivores, and frugivores compared to other agricultural systems.

Summary: Coffee agroforestry systems provide multiple benefits, including biodiversity conservation, carbon sequestration, and income generation. This study estimated the carbon stock of coffee agroforestry systems in southwestern Ethiopia and the contribution of coffee plants to carbon sequestration. The results showed that Albizia is the most compatible shade tree for coffee plants, contributing significantly to carbon sequestration.

Summary: This study explores the heat tolerance of tropical montane birds and suggests that future global warming may pose a threat to their water balance and survival. The results indicate that unshaded coffee farms increase the demand for water to maintain stability, which could have negative effects on their health and survival.

Summary: Cacao (Theobroma cacao) is a crucial commodity for economic and social development, but its production contributes significantly to carbon emissions. This study examines the carbon stocks and footprints of cacao cultivation in agroforests and monocultural systems, as well as the biophysical factors that influence carbon levels. Results reveal that cacao agroforests have higher carbon stocks (134.4 Mg C ha(-1)) compared to monocultural systems (104.7 Mg C ha(-1)), while monocultural systems have higher carbon footprints (1914.4 kg CO(2)e ha(-1)) compared to agroforests (932.1 ± 251.6 kg CO(2)e ha(-1)). Canopy cover, tree density, and soil organic carbon show significant correlations with carbon stocks, while canopy cover shows a significant correlation with carbon footprints. These findings highlight the climate-friendly nature of cacao agroforests.

Summary: This study reveals synergistic interactions between pollination and pest control, highlighting the underestimation of the benefits biodiversity provides to agriculture and human well-being when individual ecosystem services are assessed. Additionally, the results demonstrate the economic benefits of bird pest control and bee pollination services for coffee farmers.

Summary: This study investigated the geographical and genetic background of Yemeni coffee, finding a clear geographical pattern in the use of vernacular coffee names but no significant association with genetics. The results suggest the need for accurate descriptions of different coffee types based on their genetic background for Yemeni farmers.
