Agroforestry Solutions for Rural
Livelihood Challenges
Festus Akinnifesi, PhD
Regional Coordinator,
ICRAF Southern Africa Programme
Presentation at Lisbon, Portugal
The Challenges
Food, population & energy crises
Global population will increase by 50% (from
6.3 to 9 billion) by 2050
SSA population: 0.8 to 2 billion (150%);
This will require 50% more food
Food and fertilizer prices are linked to fossil
energy.
Land Use Problems in SA
Deforestation mainly due to unsustainable
harvesting of trees and farming
Maize = 1 ton/ha
Land holding = 0.4ha
Degraded
landscapes
Unsustainable harvesting of woodland
resources
Drudgery caused by scarcity of fuel
wood for domestic use
Hunger on the Small Farm
in Eastern and
Southern Africa
12 million maize-growing
farm households
60 million people

Vision and
Mission
Our Vision…
A rural transformation in the developing world resulting
in massive increase in the use of trees in agricultural
landscapes by smallholder farmers for better
livelihoods security--food security, nutrition, income,
health, shelter, energy and environmental
sustainability
Our Mission…
To generate science-based knowledge about the complex
roles that trees play in agricultural landscapes, and to
use our research to foster policies and practices that
benefit the poor and the environment.

Fodder Banks
Fodder banks are entry points for food
security, cash income.
LIVESTOCK husbandry compliments cropping: Proteinrich legumes can supplement livestock feed during the
long dry season.
Economic analysis showed
supplementation with feed
concentrates is profitable: CBA
ratios up to 3:1
Potential for blending with

The climate change community is beginning to
seriously turn its attention to forestry and
agriculture. Two critical messages from the Climate
Change Convention in Bali (Dec 2007):
-- Invest in avoided deforestation
-- Invest in smallholder carbon & poverty reduction
