The web portal for Indian Ocean agriculture and biodiversity: www.agriculture-biodiversity-io.org The islands of the Indian Ocean are home to a unique and remarkable biodiversity. They have similar environmental conditions and are subject to common threats (e.g. global changes). Conserving biodiversity is essential to agricultural production, which is itself needed to feed people. Therefore agricultural production and conservation of biodiversity must be balanced for the sustainable development of the region. A web portal was conceived in order to promote this idea. The main targets are producers, scientists, general public, press and decision-makers. The objectives are to inform, to share documentation and knowledge, to offer training about the ways of preserving biodiversity for a sustainable food production. The Agriculture & Biodiversity Web Portal offers information on the strategies of Indian Ocean Commission member states, regulations and ongoing activities & laboratory research in the fields of agriculture and biodiversity. It offers tips for professionals to improve their daily practices, and educational tools for teachers to educate their students. Specialists can become contributor, post information on public forums on the website * and have a private area for major agriculture and biodiversity projects. The visitor can also get access to a specific tool to make contact: the Synaptic web platform. People working in the environment, biodiversity or agriculture can register directly on this platform, which allows to find collaborators.
