The Crop Wild Relatives (CWR) In situ Conservation Manual [2] (8.2 MB) is based on the Crop Wild Relatives Project implemented by the GEF and UNEP. The Project has been conduct in five countries; Armenia, Bolivia, Madagascar, Sri Lanka and Uzbekistan, which are all important centers of diversity for CWR.
The Manual captures the important practical experiences of the participating countries and ensures best practices and lessons learned are documented and disseminated to the wider conservation community. By so doing, the Manual also fills an important gap in the in situ conservation literature currently available, since, at present, there is no clear, practical publication to guide practitioners in the many processes and methodologies necessary to implement national CWR action plans and strategies.
The manual has been translated into English [2] (8.2 MB),
French [3] (4.1 MB) and
Spanish [4] (4.8 MB). For ease of use, PDFs of individual chapters in the three languages are also available for download in the Capacity building - eLearning section of the portal, under their respective modules.
Crop Wild Relatives are plant species which are more or less closely related to crops. They are a vital resource by providing a pool of genetic variation that can be used in breeding new and better adapted varieties of crops that are resistant to stress, disease, drought and other factors. They will be increasingly important in allowing crops to adapt to the impacts of climate, thus safeguarding future agricultural production. However, CWR themselves are vulnerable to changing climate. Until recently, the main conservation strategy adopted for CWR has been ex situ - through the maintenance of samples as seed or vegetative material in various kinds of genebank or other facilities. Now the need to conserve CWR in their natural surroundings (in situ) is increasingly recognized. This allows their populations to continue evolving and generate new genetic variation that is adapted to changing conditions.
Until now, experience in conserving the wild relatives of crops in situ has been very limited. Recent research co-ordinated by Bioversity International has produced a wealth of information on good practices and lessons learned for their effective conservation This book captures the important practical experiences of countries participating in this work and describes them for the wider conservation community.
