Kyoto protocol : Satellite land-use snapshot
To fulfil the country’s engagements made under the Kyoto Protocol, in 2007 France had to provide national land use statistics, with particular focus on forest cover. French Guiana is of prime significance in this respect, with its 8 million hectares of forest. The short operating time available precluded a complete ground-level survey, therefore the only feasible operational solution was to use satellite imagery. The land use mosaic produced by IRD’s Space unit gave the first recorded coverage of the whole surface of Guiana, showing the forest and the areas cleared for agriculture or goldpanning. The resulting map and the methodology applied by the unit “Espace et l’Inventaire forestier national” were presented at the conference of the Intergovernmental Panel on Climate Change (IPCC) held in December 2007 in Bali (Indonesia).
Ruby and sapphire formation occurs deep in the lithosphere in a regime of extremely high pressures and temperatures. Although it is known that most of these gem stones, classified as corundums, were torn from the Earth’s crust by a magma generated in the mantle before being transported towards ...
How can satisfactory crop yields be obtained without spreading large quantities of chemical fertilizers on the fields? To answer this question, IRD researchers and their scientific partners (1) are examining an unusual symbiotic association, between an aquatic leguminous plant, Aeschynomene and ...
Tunisia’s arid regions: how can desertification control and socio-economic development be reconciled?
How can socio-economic development and environmental conservation be reconciled in the difficult context of a region threatened by desertification? That is the objective of the research project IRD researchers and their local partners initiated in Jeffara, in South-East Tunisia. The team of ...
The research presented in the three videos here below was implemented from 1998 to 2003 by the Mountain Agrarian Systems (SAM) Program, a joint research project of the Vietnam Agricultural Science Institute (VASI), the Institut de Recherche pour le Développement (IRD), the Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD), and the International Rice Research Institute (IRRI).
