The Network of Rural Radios of Developing Countries www.farmradio.org, the CTA Rural Radio Program www.cta.int, Radio Canada International www.rcinet.ca, Destinationsante www.destinationsante.com have joined CRTV (Cameroon Radio and Television) and in RUT FM (Tankou University Radio) to contribute to the improvement of SOS Environment services. They regularly contribute information to enrich this magazine programme. That is the case with Destination santé for health programs; RRRPD for ECHOS newspaper and radio texts on development; CTA Rural Radio Program for the information packages on diverse agricultural development subjects; Canadian International radio for reports and interviews on diverse social and development subjects. Others such as CRTV Western provincial station and RUT FM air SOS Environment in the West Province. Our partnership with radio Swiss International www.rsi.ch is limited to our participation in the SRS (Switzerland Radios of the South) competition. We were a prize-winner in 2002. Our programme then received a support in material worth 4 000 Swiss francs.
