Última Soil Health Changes Over a 25-Year Chronosequence From Forest to Plantations in Rubber Tree (Hevea brasiliensis) Landscapes in Southern Côte d'Ivoire: Do Earthworms Play a Role? ArchiMer Tondoh, Jérôme E.; Dimobe, Kangbéni; Guéi, Arnauth M.; Adahe, Léontine; Baidai, Yannick; N'Dri, Julien K.; Forkuor, Gerald. The agro-ecological drawbacks of the spread of rubber tree plantations in Côte d'Ivoire since the 1990's are obvious even though they have not been properly investigated. They consist of biodiversity loss, land degradation and food insecurity, which have extended into the existing cocoa-led degraded areas whose rehabilitation have unfortunately not started. This situation increases not only the threat on soil health status but also undermines the capability of soils to deliver ecosystem services that are key to sustainable agricultural production. The current study took advantage of a chronosequence in rubber tree landscapes to assess soil health deterioration in general and possibly earthworm-mediated role in soil health changes. The hypothesis... Tipo: Text Palavras-chave: Biodiversity; Earthworms; Functional groups; Land use change; Soil degradation; Soil threats; Rubber tree plantations.

Small reservoirs (SRs) are essential water storage infrastructures for rural populations of Sub-SaharanWest Africa. In recent years, rapid population increase has resulted in unprecedented land use and land cover (LULC) changes. Our study documents the impacts of such changes on the water quality of SRs in Burkina Faso. Multi-temporal Landsat images were analyzed to determine LULC evolutions at various scales between 2002 and 2014. Population densities were calculated from downloaded 2014 population data. In situ water samples collected in 2004/5 and 2014 from selected SRs were analyzed for Suspended Particulate Matter (SPM) loads, an integrative proxy for water quality. The expansion of crop and artificial areas at the expense of natural covers controlled... Tipo: Text Palavras-chave: Small reservoirs; Sub-Saharan Africa; Anthropogenic pressures; Water quality.
