Despite being the driest inhabited continent, Australia has one of the highest per capita water consumptions in the world. In addition, instead of having fit-for-purpose water supplies (using different qualities of water for different applications), highly treated drinking water is used for nearly all of Australia’s urban water supply needs, includ...
En présence d'une demande évaporatoire forte et lorsque les précipitations sont faibles, un flux d'eau ascendant des couches profondes saturées en eau vers les horizons superficiels desséchés peut se produire dans le sol : c'est le processus de remontées capillaires, bien décrit en situation de nappe superficielle. L'objectif du travail présenté ic...
Spatial and temporal variability of soil water extraction from the root zone affect soil water balance determination. The number of sensors installed in the root zone in studies addressing water balance is still set arbitrarily. This study provided an investigation of the water extraction process by banana (Musa spp.) roots by (i) determining the v...
Summary Human population is increasing faster than ever in the history. There is an urgent need to scale up food production in order to meet up with food demands, especially in Sub-Saharan Africa. In Ogun-Osun River Basin, Nigeria, more than 95% of the crop production is done under rainfed conditions. Fluctuation in rainfall as a result of climate ...
RESUMO. As grandes secas do passado (1959, 1976, 1989 ou 2003) resultaram em danos significativos às atividades essenciais para a economia da Bretanha, como a agricultura. Por isso, no contexto das mudanças climáticas, parece importante analisar possíveis mudanças quanto ao o risco de seca na escala regional. Essas mudanças são estudadas por meio d...
La Bretagne a connu par le passé des sécheresses majeures. Celles-ci ont eu des conséquences dommageables sur des activités importantes pour l'économie de la région, telles que l'agriculture. Dans un contexte de changement climatique, il apparait donc important de cerner les évolutions possibles du risque de sécheresse à l'échelle du territoire. Ce...
