Abstract:
Agroforestry Systems (AFS) are integrated land use systems involving trees,
agricultural crops, and animals simultaneously or sequentially, with the
objective of sustainably increasing their total productivity per unit area.
Despite strong literature evidence describing the benefits of agroforestry to
livelihoods in other parts of the world, there is little information as such in
Soin Ward of Kericho County, where sugarcane competes with tea as a
major cash crop. This study aimed at classifying agroforestry systems and
evaluating their socio-economic benefits in Soin Ward, Kericho County,
Kenya. The study adopted a qualitative research design through the
administration of pretested questionnaires on types of agroforestry systems,
the scale of production, land utilisation, preference of trees and sugar cane
varieties and their interactions with 384 respondents in lower, upper, and
midland parts of Soin Ward. Four (4) classes of agroforestry systems were
identified that comprised (48.2% agrosilvopastoral, 31.6% agrosilvicultural,
and 20.2% silvopastoral); (16.2% protective and 83.8% productive); (45.7%
subsistence and 54.3% commercial), and integrated farm-based agroforestry
47.4%, homestead (6.8%), animal farm (31.4%), dairy farm (1.4%), and
forest land (13%) respectively. The majority of the respondents (42.7%)
preferred Grevillea tree species for blending with sugarcane in a tree sugarcane agroforestry system in comparison with cypress (29.4%),
eucalyptus (15.1%), casuarina (12.6%), and calliandra (0.2%) respectively.
Sixty (61.7%) plant trees along the boundary, 24% as woodlot, hedge raw
(8.9%), intercropping/mixed (3.1%), and alley cropping (2.3%). Direct
benefits from the identified agroforestry systems include; income (67.6%),
food (8.3%), and employment (24.1%). Indirect benefits include provision of biofuel (21.9%), enhanced soil fertility (21.1%), bio drainage (20.4%),
biodiversity conservation (19.4%), carbon absorption (17.2%),
improvement of social amenities such as roads (27.2%), markets (25.8%),
hospitals (19.3%), schools (18.5% and electricity (9.2%).Constraints faced
by the agroforestry systems include; long waiting payback (39.2%), limited
possibilities to sell products (28.3%), labour intensive (27.8%), and
knowledge and technology gap (4.7%). Such results are useful for policy making decisions towards afforestation and improved livelihoods in Kenya.
