OLF users include several segments:

·        International partners of the European Union that implement their own environmental monitoring system. This is the case in particular of FAO and UNEP

·        Services of the European Commission. In particular the Joint Research Centre has announced the establishment, in partnership with DG DEV, DG AIDCO, DG RELEX and DG ENV, of an Observatory for the sustainable development of Africa, both to serve internal needs of EC services, and if needs arise, to provide support to partner institutions in the framework of EC-supported projects

·        Technical services in partner countries whose role is to assist decision makers with responsibilities in policy orientation, project management and environmental reporting in the regions of interest covered by OLF. This is the case in particular of the Space Research Institute (Moscow) for Boreal Eurasia, and of the PUMA network in Africa, whose secretariat is hosted by EUMETSAT, and which is represented by technical experts from national and regional centres of expertise in Africa, such as: Centre AGRHYMET (Niamey), ICPAC (Nairobi), METTELSAT (Kinshasa), RRSU (Gaborone), RCMRD (Nairobi), CSE (Dakar), Direction de la Météorologie Nationale (Maroc), ISCW (Pretoria)
