The challenge of collaboration in the management of crop genetic diversity

The authors give an overview of crop genetic diversity as a crucial element in total agrobiodiversity. Farmers need a certain degree of genetic diversity for their survival and resilience, especially in marginal areas where modern, improved varieties have not brought any profitability. Finding the right mix between (re)creating and conserving biodiversity and introducing improved varieties is the big challenge. Formal, or institutional, seed systems and informal, farmers' seed systems operate parallel to each other and must be brought to cooperate better. Examples of innovative approaches..
