9.4 Implications for Development
As described in the potato and sweetpotato case studies, adapting smallholder farming to climate change can be achieved by growing varieties that can cope with high
temperatures, erratic rainfall patterns, and even drought. However, functional seed
systems are essential for delivering such varieties and providing healthy seed.
Research is revolutionizing this adaption to climate change, from new breeding
approaches (e.g. ABS), multiplication techniques (e.g. apical cuttings) and on-farm
seed management techniques (e.g. Triple S), to new approaches for engaging with
specialized seed producers, seed users, markets and regulatory agencies. The clear
links between climate change, improved varieties and seed systems illustrate the
importance of interdisciplinary collaborations to ensure that scientific, technical,
socio-economic and gender aspects are considered in such interventions.
Given the need for strict quality control to manage the high risk of seed degeneration in VPCs, developing seed systems to deliver climate-smart varieties requires
a multi-stakeholder approach, especially if support for a project is limited. Sustaining
seed systems beyond project life is a key challenge that can be addressed through
well-targeted partnerships that drive the process while supporting those who use the
system with the technologies to deliver them.
