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)

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
