2. A worldwide cocoa production usually
characterized by a move of production areas
to the detriment of forest
Why ?
A model based on :
the settlement of cocoa
plots after a forest
clearance
the management of cocoa
trees with no shade, or a
light one
the use of chemicals
inputs
3. An intensive cocoa model valuable only if
all environmental factors are favorable
If not …
Abandon of old cocoa orchards
New forest clearance to set up new cocoa plots
4. Role of cocoa agroforestry systems in this context ?
Vanuatu
Cameroon
Brazil
