… ongoing efforts to develop and implement a sustainable strategy for PGR conservation in the Region
Many constraints such as replacement of traditional by commercial varieties, but most importantly… scarcity of water
Genetic variation is key component of biodiversity
With the objective of guiding investment decisions of the Trust. … focused on ex situ conservation in genebanks
These outputs have been at least partly accomplished
- … ICARDA genebank
Two photos taken within days of one another (in Bangladesh and in Kenya). Unpredictability.
Maps are from Burke et al recent paper. This map is for maize area. Dark blue grid cells have total overlap with climate of past 10 years, dark red cells have absolutely no overlap. Some countries – Tanzania have good overlap. Others – Mali, Niger, very poor overlap. WITHIN COUNTRY. Need to source material from other countries, not currently conserved in genebanks. Farmer varieties – landraces – with inherent genetic diversity, will be better able to adapt, and are very poorly represented in collections.
Holistic approach to PGR conservation Particularly important when unpredictable changes of climate
-data on ensuring effective collection of agrobiodiversity. Mapping of Phaseolus wild relative records, from many different data sources, combined with eco-geographic data. Zones in the map indicate places in which the species is likely to exist and no genebank accessions have been collected. Inset shows greatest species richness in Mexico.
Increasing adaptedness through the choice of provenances that demonstrate high survival and/or phenotypic performance under given environmental conditions Provenance (common garden) field trials since 1840 Geographic patterns of variation Growth and survival rates strongly influenced by climate
Prof. Ahmed Tawfik from Egypt elected as Chair.
Towards a Regional strategy on plant genetic resources Jozef Turok Regional Director, Bioversity International El Tahir Ibrahim Mohamed Agricultural Research Centre, PGR Unit, Sudan
Committed to harnessing science of biodiversity towards its conservation and use in development
Mission: “…undertakes, encourages and supports research and other activities on the use and conservation of agricultural biodiversity, especially genetic resources, to create more productive, resilient and sustainable harvests”
Works in partnerships with others
Agricultural biodiversity in West Asia and North Africa
Important centres of plant biodiversity (Near Eastern, Mediterranean and Central Asian)
Flora of 32,000 species of higher plants with a high proportion of endemic and threatened
Origin of many major temperate crops (cereals, pulses, vegetables, spices, oil crops, pasture and forage species, dyes, fruit and nut trees, timber tree species)
Diverse range of wild relatives, weedy forms and traditional varieties, landraces
Scarcity of water (and cultivable land)
Largest food-importing region in the developing world
Biodiversity is affected by changes in the environment: extinction of species, fragmentation
Loss of genetic variation: the changes are continuous - quantitative and qualitative effects
The changes of climate are generally inert (unlikely to return to the original conditions)
Biodiversity is essential for environmental health
Biodiversity and especially genetic resources can be managed and used for adaptation
Key role in helping agriculture to adapt to climate change
Towards a Regional strategy for the conservation of PGR
Initiated by the Global Crop Diversity Trust and developed in consultation with the Association of Agricultural Research Institutes of the Near East and North Africa (AARINENA) with input from a wide range of partners, stakeholders
Adopted in July 2006, Dr M. Zehni facilitator
“… further development of the strategy and related networking capacities in future AARINENA workplans leading to a PGR coordinating mechanism in the Region…”
