ECA continues to support Member States to develop their nationalspatial data infrastructures (NSDI), which also enable countries tomonitor and address some of Africa’s current pressing issues – theimpact of climate change, water scarcity, energy and food shortages,environmental challenges, disaster management and disease mappingand intervention. ECA will continue to support the developmentof regional spatial geo-databases for the priority areas defined byregional initiatives of the African Union, NEPAD and other continentalbodies.The foundation of accurate geospatial information starts with a uniformcoordinate reference system. ECA will pursue, in partnershipwith the African Union Commission, efforts to develop through theAfrican Reference Frame (AFREF) Project, a unified geodetic referenceframe for Africa.This is also exemplified by the establishment of a new Geodetic ReferenceNetwork for Ghana to address the rising demand for costeffectiveland delivery and management processes in country. Thefirst phase of the renewal of the Geodetic Reference Network (GRN)was completed with the provision of the basic infrastructure in andaround the Golden Triangle of Ghana for using the Global Navigationsby Satellite Systems (GNSS) technology. This prepared the country tojoin the proposed continental AFREF led by ECA. In addition, moreAfrican countries, through support from Trimble, the world leader inthe manufacturing of professional Global Positioning Systems havereceived equipment for five GPS reference stations. The referencestations will form part of the GPS network that will define a uniformAfrican (Geodetic) Reference Frame (AFREF) and the agreed installationsites are Botswana, Niger, Tanzania, DR Congo and Ethiopia.ECA continues to collaborate and coordinate its activities in supportof Africa’s developments in the field of geoinformation with otheragencies in the UN system, international and regional associationsand programmes and other development partners as an importantvehicle for mobilising financial resources and technical know-how.We will strengthen our efforts to develop partnerships with regionaland international organisations through contribution and participationto several initiatives on geospatial science and technology atvarious levels.
