Abstract

The World Agroforestry (ICRAF) in Kenya plays a key role in conserving tree genetic diversity, thereby contributing to the delivery of ecosystem services in tree-based production systems. This study explored the benefits of using the two most popular fodder tree species among smallholder farmers, sourced from the ICRAF genebank: Calliandra calothyrsus (Calliandra) and Gliricidia sepium (Gliricidia). Through a survey of key informants and genebank users, we examined the benefits derived from the adoption of Calliandra and Gliricidia and the unique role of the ICRAF genebank as the main source of tree germplasm for Kenyan smallholders. The constraints to germplasm access could limit protein fodder supply and the intensity of fertilization in farmers’ fields, which in turn could affect productivity in livestock and maize sectors in Kenya. We find that improved food security, higher incomes, increased milk production, reduced vulnerability to drought, reduced soil erosion, and enhanced soil fertility are identified as the main farmer-perceived benefits linked to the use of Calliandra and Gliricidia. The findings demonstrate the importance of agroforestry in the delivery of ecosystem services, in the light of climate change and heightened pressure for sustainable agricultural practices, and the crucial role of the genebank in conserving and distributing unique, high quality tree germplasm.
