of the Convention on Migratory Species (CMS). Bert Lenten

1996 and has made a significant contribution to the successful
development of the Agreement since then.

of migratory waterbirds across Africa and Eurasia.

in organising the World Migratory Bird Day (WMBD) initiative
in close cooperation with the Convention on Migratory Species
(CMS). The global campaign devoted to celebrating migratory
birds and for promoting their conservation worldwide is

conducted by the AEWA Secretariat and has managed to stimulate
an increasing number of events celebrated around the world
each year.

Mr. Lenten has also played a leading role
