Functions
Agroforestry is an integrated approach of using the
interactive benefits from combining trees and
shrubs with crops and/or livestock.
It combines agricultural and forestry technologies to
create more diverse, productive, profitable, healthy
and sustainable land-use systems.

Alley Cropping
(cid:198) Alley Cropping is broadly defined as the planting of two or
more sets of single or multiple rows of trees or shrubs
(hedgerows) in wide spacings, creating alleys within which
agricultural, horticultural or forage crops are cultivated.

= declares that for sustainable development, soils (soil
functions) need to be protected from degradation.
(cid:121) The main threats to soil functioning abilities are identified as
(cid:121) (1) decline in organic matter
(cid:121) (2) soil erosion
(cid:121) (3) compaction
(cid:121) (4) salinisation
(cid:121) (5) landslides
(cid:121) (6) floods
(cid:121) (7) contamination
(cid:121) (8) sealing
Threats 1-5 are area and soil specific in their appearance
