|14. Agroforestry research in Kenya: an overview|
This project, which began in 1991, is also part of the AFRENA network. The leadership is provided by KARI, and research is carried out in the coffee-based land-use system of the central highlands. The main emphasis is on on-farm research and only technology testing and development is carried out on station.
The main constraints to D&D in this land-use system were identified as:
· Decline in soil fertility
· Soil erosion
· Dry season fodder shortage
· Shortage of firewood and other wood products.
The team conducting the D&D also noted a need to intensify income-generating activities such as fruit production.
Activities carried out so far include:
· An ethno-botanical survey
· The establishment of on-farm fodder trees in fodder plots and multi-storey boundary planting
· Screening of Flemingia macrophylla for soil-erosion control and mulch in coffee
· On-station hedgerow intercropping for soil fertility
· D&D of agroforestry technologies for fodder production and soil fertility
· Monitoring and evaluation of production and marketing of fruit and wood products
· On-station MPT screening
· Establishment of MPTs in mature Napier grass plots
· On-station assessment of new Grevillea germplasm imported from Australia
· Study of the impact of homegardens on household economy
· Factors influencing labour productivity in hedge pruning.
