Authors’ Vision
To create a volume that links:
• Research principles and
practices to assess,
access, and value crop
genetic diversity in farmers’
fields
• The evolutionary capacity
of traditional crop varieties
• The benefits obtained by
the farmer or farming
community in using this
diversity
A common theme throughout the book is the way in which
traditional varieties are able to adapt to changing conditions.Photo: D. Jarvis

Main features of the book
• Integrated monograph, rather than an edited volume of separate chapters
• Evidenced based: relies on more than 20 years of research globally
• Multidisciplinary: genetics, agronomy, ecology, sociology, economy, policy
• Practical approaches and methods with concrete examples
• General overview of primary literature, for future follow up on specific points

The first 10 years (1995-2005) “Strengthening the Scientific Basis of In Situ Conservation on Farm”
1990s- the challenges
Science and practice of in situ conservation lags behind policy commitments of the CBD to its implementation
No scientific basis on how “to do” In situ Conservation
Ex situ facilities can not accommodate full range of useful diversity and do not conserve dynamic processes of crop evolution and farmer management
The story behind the book
The second 10 years (2006-2016)Conservation and use of traditional crop varieties in sustainable
agricultural production and agro-ecological resilience

The Authors
The authors’ disciplines span the fields of ecology,
botany, genetics, agronomy, plant breeding, anthropology,
economics, and policy.
Over the last 20 years, the authors have worked in a joint
international integrated collaborative program, where
partners from developing and more advanced economies
have met, organized and managed a program with the
common goal of providing tools and methods for tapping
the potential of crop genetic diversity on-farm.

Chapters 1, 2 and 3 (Origins)
What is a traditional variety or landrace, the origin of today’s
crops, and the development of international agendas on the
conservation and use of their genetic diversity

Chapter 13 (The future of traditional varieties)
• Productivity in low input environments, extreme temperatures and
water, degraded soils
• Unpredictable fluctuations in temperature, rainfall, frost, pest, disease,
• Growing consumer demand for diverse and natural food-based
products
• Interested of communities to retain control over their crop resource
