French version available in IDRC Digital Library: Systèmes d'information géographique participatifs (SIG-P) dans la gestion des ressources naturelles et la sécurité alimentaire en Afrique : ict4d article, janvier 2011 | Training of technical staff of municipal councils and agricultural centres in the use of GIS tools for hydrological modeling and soil conservation has been well attended in all three training modules, and deemed successful. Participants were satisfied with the mastery of P-GIS tools as a means to control and coordinate management and rational use of water resources. Based on the training, students have decided to work towards establishing a partnership with the University of Abomey-Calavi, through its laboratories to assist municipalities in capacity building and further training.

Four plots have been planted with homogeneous material of Pinot noir cultivar on typical soils of Chamoson area (Valais, Switzerland). Conducted from 1997 to 2000, this research allowed pointing out the influence of water nutrition on agronomical and oenological potential of Pinot noir. In a situation without water restriction, vigour was clearly higher and budburst was delayed. In the must, soluble solids content was lower in absence of water constraint, while malic acid and nitrogen contents were higher. Meanwhile, pH remained relatively constant due to higher potassium content. In fact, any situation inducing regular and moderate water restriction during ripening did led to wines with more polyphenols and more qualitative tannins, which were preferred by the panel of tasters.
