Description Traditional agroforestry parkland systems
in Burkina Faso are under threat due to human
pressure and climate variability and change, requiring
a better understanding for planning of adaptation.
Field experiments were conducted in three climatic
zones to assess Sorghum bicolor (L.) Moench (Sorghum)
biomass, grain yield and harvest index in
parklands under different rainfall pattern and compared
to simulations of sorghum biomass and grain
yield with the Water, Nutrient and Light Capture in
Agroforestry Systems (WaNuLCAS) model for calibration
and parametrisation. For planning adaptation,
the model was then used to evaluate the effects of
different management options under current and
future climates on sorghum biomass and grain yield.
Management options studied included tree densities,
tree leaf pruning, mulching and changes in tree root
patterns affecting hydraulic redistribution. The results
revealed that sorghum biomass and grain yield was
more negatively affected by Parkia biglobosa (Jacq.)
Benth. (ne´re´) compared to Vitellaria paradoxa C.
F Gaertn (karite´) and Adansonia digitata L. (baobab),
the three main tree species of the agroforestry parkland
system. Sorghum biomass and grain yield in different
influence zones (sub-canopy, outside edge of canopy,
open field) was affected by the amount of precipitation
but also by tree canopy density, the latter depending
itself on the ecological zone. The harvest index (grain
as part of total biomass) was highest under the tree
canopy and in the zone furthest from the tree, an effect
that according to the model reflects relative absence of
stress factors in the later part of the growing season.
While simulating the effects of different management
options under current and future climates still requires
further empirical corroboration and model improvement,
the options of tree canopy pruning to reduce
shading while maintaining tree root functions probably
is key to parkland adaptation to a changing
climate
