Achieving sustainable food security in Sub-Saharan Africa is one of the main challenges facing African governments and the international community. The 2007–2008 food crisis and ongoing chronic hunger problems clearly demonstrate that millions of people on the continent, including in relatively stable countries such as Kenya, are dangerously vulnerable to(More)
A novel anaerobic, alkaliphilic, Gram-positive staining bacterium was isolated from a hydrothermal chimney in the Prony Bay, New Caledonia. This strain designated FatMR1T grew at temperatures from 20 to 55 °C (optimum 37 °C) and at pH between 7.5 and 10.5 (optimum 8.8–9). NaCl is not required for growth (optimum 0.2–0.5 %), but is tolerated up to 3 %.(More)
Active carbonate chimneys from the shallow marine serpentinizing Prony Hydrothermal Field were sampled 3 times over a 6 years period at site ST09. Archaeal and bacterial communities composition was investigated using PCR-based methods (clone libraries, Denaturating Gel Gradient Electrophoresis, quantitative PCR) targeting 16S rRNA genes, methyl coenzyme M(More)
In many parts of the world, rural livelihoods are characterized by a high degree of vulnerability to climate change, market volatility, and political unrest. Increasingly, the concept of resilience is being used to inform development initiatives aimed at building the capacity of rural households and communities to cope, adapt, and transform in the face of(More)
High amounts of hydrogen are emitted in the serpentinite-hosted hydrothermal field of the Prony Bay (PHF, New Caledonia), where high-pH (~11), low-temperature (< 40°C), and low-salinity fluids are discharged in both intertidal and shallow submarine environments. In this study, we investigated the diversity and distribution of potentially hydrogen-producing(More)
