6. The Potentials of AF
Major drivers of
deforestation
Potentials of AF Enabling factors to be in
place
Small-scale agriculture
(slash and burn agriculture)
Diversify income sources
from fruit trees and
commodity crops;
AF based sustainable
intensification pathways
Investment and technical
support
Unsustainable logging Onfarm timber (e.g.
Cameroon)
Tree and land tenure,
Market access,
Appropriate taxation systems
Livestock rearing Fodder and sustainable
agropastoral systems
Technical support,
Investment
Charcoal and fuelwood Smallscale woodlots and
onfarm timber as supply
sources
Right tree species for the
right places,
Farm management techniques
Mining Agroforestry based
mining area reclamation
(e.g. in China)
Policy support,

7. — “Green fertilizers increased the average yield by up to 1.6 tonnes per
hectare over these smallholder farmers’ practices.”
— “At the estimated rate of maize consumption of 1.5 kilograms per
person per day, the incremental maize yield provided by green
fertilizers contributes the equivalent of 6 months’ worth of additional
maize for a farm family of six or 7 months’ worth for a farm family of
five.”
— “The probability of increasing maize yield over continuously cropped,
unfertilized fields by more than 1 tonne per hectare was 30–63% with
green fertilizers.”

12. Promising national moves in
promoting AF
Article 69. (1) (b) “The
State shall work to
achieve and maintain a
tree cover of at least ten
per cent of the land area
of Kenya” (Constitution
of Kenya 2010)
11
Kenya
Commitment to
restore close to 15
million ha of degraded
forest and land (Bonn
challenge, etc.)
Ethiopia India
The only country
with a national
agroforestry policy!
13. Hence, agroforestry could be a
useful practical mechanism to
divert the pressure on African
forests.
12
But we have serious issues
that need to be addressed!

that farmers are not exposed?

16. 2. Insecure Land and Tree Tenure
15
If farmers do not have the secure right to land, investments in perennial
crops is not sustainable. See Hansen et al (2005) for more.
17. 3. Lack of proper value for tree
products [The middlemen effect]
Often farmers who do not have good market
access loose a lot to the middlemen who benefit
from the farmers efforts. E.g.
◦ Coffee in East Africa (Pinard and Aithal 2008)
◦ Timber all across tropical and subtropical parts of
Africa
◦ Cocoa

18. 4. Constraining regulatory
mechanisms
— Taxation systems for tree products
— Demands for complicated standards that
farmers may even not understand well.
17
19. Issues of concern
— Population growth:
— Urbanization: is the migration of the
youth going to create labor shortage in
rural areas?
— Sustainable consumption – if what is
produced is not consumed properly, we
create
