ELC for CWR
Mauricio Parra QuijanoEcogeographic land characterization for CWR diversity and gap analysis Training workshop 26–27 February 2014, Room UG08, Learning Centre, University of Birmingham
Diversity assessment and gap analysis

ELC overview
It is a made-to-measure map according to researcher needs to discriminate adaptive scenarios within a work frame
≠ Abiotic adaptation
≠ Adaptive geneticdiversity

ELC overview
How to delineate different adaptive scenarios in a work frame?

ELC overview
How in the past most of these type of maps were delineated?
DMEER - EEA, 2003

ELC overview
But what about abiotic masked conditions related to plant physiology-adaptation?

ELC overview
Right now we have enough tools to achieve our own plant abiotic-adaptive maps thanks to
Geographic Information Systems and…

If you know
… the resulting abiotic adaptive scenarios …
and you also know the total possible scenarios for the target species (from known populations)

… it’s about time
Why this approach works better for CWR?
Human influence (domestication)
Specific environmental adaptation
![Page 13: Ecogeographic land characterization for CWR diversity and gap analysis Workshop - presentation 1](https://reader033.vdocuments.mx/reader033/viewer/2022060201/55999e151a28ab79658b45c8/html5/thumbnails/13.jpg)
For ex situ conservation can be used as a base of:
Massive/fast ecogeographic germplasm characterization
Representativeness assessment in germplasm collections
Core collections
And complement of other interesting methods such as:
Optimized germplasm collection
FIGS
Ecogeographic Land Characterization Maps

For in situ conservation this methodology has been used only as a criterion in studies to:
Identify populations with high priority to be conserved
Identify protected areas which contain target environments / are covering priority populations
Determine optimal places for genetic reserves
Establish CWR national strategies
Prioritize sites to focus on on-farm conservation efforts
