concludeti that there are ar least six major research thcmeh which cut iic.ross rhr. various
ecoregional initiatikes currently underway or planned in the rG1AK. 'Table 2 c.untains a lirt
of the suggestetl generic research therncs. po.;sihlt- initial target zone\. ;~nd polrntial io-
convenors. The suggestion is that the co-convenors would reprrsrnt rncchnisrns for cn\uring
that a global synthesis of rebearch and knowledge (111 the the~ne.; was made a\ailable to a11
eco~egional players and others who were intcrestcd.

to the proposed Desert Margins Initiative. Hence it is anticipated that c.ollaborati~lp institurions
in the Desert blargins initiatives woi~ld br ;thle to benefit \ipnifici~ntly from rhr c.ro~s-cutti~~g
research knowledge and synthesi., that would be undertaken 111 the proposed SSWNbiKI.
