Presentation Outline • • Who and what is RANET? What does RANET do? Core RANET principles and philosophies. Overview of Technologies – Satellite – Community FM – Other • Where does RANET work?
Who are we? “Just tell me where it has rained, and I will know what to do. ” - A nomad from Niger
Who are we? The RANET program began in Africa in 1998/9, following the experience of Seasonal Outlook Forums. It was recognized that benefits from advances in science and applications could only be realized if populations outside central cities could be reached. - Africa: 1998/99/00 -> present - Pacific: 2003 -> present - Asia, Indian Ocean: 2005
Who are we? RANET is a cooperative effort of various national, regional, and international partners, who seek to:
Who are we? RANET is a cooperative effort of various national, regional, and international partners, who seek to: - Make weather and related environmental information more accessible and useful to rural and resource poor populations in order to aid dayto-day resource decisions and prepare against natural hazards.
Who are we? RANET is a cooperative effort of various national, regional, and international partners, who seek to: - Make weather and related environmental information more accessible and useful to rural and resource poor populations in order to aid day-to-day resource decisions and prepare against natural hazards. - Improve the dissemination capacities of national hydro-meteorological and related national services, NGOs, and other information producers, thereby increasing the profile of and active value of these organizations to local populations.
What we do? RANET INCLUDES: - Web and Internet - Community FM Radio - HF Radio - SMS (Cellular Text) Messaging - Other Equipment Use and Maintenance - RANET Community Building: Newsletters, etc - Web Hosting - Network Development and Management - Maintain Satellite and Associated Server Systems - Pilot and Training Activities - Test and Identify Communication Solutions
Core principles? RANET IS A CONCEPT All activities are done in collaboration with, and with the approval of, the communities and national meteorological and associated services.
Core principles? RANET IS A CONCEPT Ensuring sustainability and maintenance of systems is a priority of all RANET activities, therefore we encourage local ownership and use of communication systems for multiple purposes such as education, health campaigns, community discussions, etc.
Core principles? RANET IS A CONCEPT RANET also works to build upon and augment existing networks and means of communication.
