On-farm cocoa yields increase with canopy cover of shade trees in two agro-ecological zones in Ghana
, 2019 Despite Ghana’s large contribution to global cocoa production, average yields are low. Policymakers and practitioners are calling for implementation of a climate smart strategy by increasing yields and augmenting shade tree cover in cocoa systems ...

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]
, 2008 : In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.

Shade trees decrease pest abundances on brassica crops in Kenya
Agroforestry Systems, 2019 Agroforestry practices may mitigate the current loss of biodiversity and ecosystem services due to deforestation and agricultural intensification. To examine the effects of agroforestry on the ecosystem service of pest regulation, we assessed pest ...

Acta Scientiarum Polonorum: Hortorum Cultus, 2020 High temperature stress can be detrimental to plants, resulting in reduced fruit yield and increased incidences of fruit disorders. One strategy that farmers can use to maintain or increase their yields in the face of a changing climate is to adjust of ...

A Study of Perceived Nature, Shade and Trees and Self-Reported Physical Activity in Denver
International Journal of Environmental Research and Public Health, 2019 (1) Background: Current evidence on the association between greenery and physical activity (PA) remains inconsistent. Most studies on this association use objective measures of greenness, which do not reveal people’s perceptions of greenness in ...
