Farmer segmentation for enhancing technology adoption and smallholder dairy development

November 2017

Despite various interventions, smallholder dairy farming in large parts of the tropics remain characterised by low productivity, restricted market participation, and viability challenges. The problem lies in the unavailability, low adoption rates and non-adoption of available improved smallholder dairying technologies. Using Rusitu and Gokwe smallholder dairy projects in Zimbabwe as a case study, this paper explored...

Uprooting resistance of two tropical tree species for sand dune stabilization

November 2017

Coastal windbreak restoration is important in Taiwan for agroforestry and sand dune stabilization. Australian pine (Casuarina equisetifolia Forst.) is the main species in windbreaks. It often suffers from serious uprooting and waterlogging damages, whereas sea hibiscus (Hibiscus tiliaceus L.) is more resistant to wind and tolerant to waterlogging. It is suggested that sea hibiscus can be substituted for Australian pine...
