This book chapter elaborates on the spread of mobile phone use across Kenya and the opportunities this brings to improve service delivery for smallscale farmers. International and local companies have already started to capitalize on these opportunities, although many mobile phone-enabled services (m-services) are still at an early stage.

The authors assesses the key factors that have helped the local innovation scene to emerge and reviews existing agricultural m-services that provide Kenyan farmers with access to information and learning, financial services, and input and output markets. »
