PEZZOPANE, José Ricardo Macedo et al. Climatic risk zoning for Conilon coffee in Espirito Santo, Brazil. Rev. Ciênc. Agron. [online]. 2010, vol.41, n.3, pp.341-348. ISSN 1806-6690.  http://dx.doi.org/10.1590/S1806-66902010000300004.

A frequencial analysis of the crop water requirement index of the Conilon coffee (Coffea canephora), determined for the occurrence of relative evapotranspiration (ETr/ETo) > 0.65 above 80% of the years, was carried through for the phenological stages of the flowering, bean formation and vegetative growth. The areas with climatic risk of water deficit were zoned by a geographic information system considering simultaneously the three phenological stages. The results showed that due to heterogeneous rain characteristics, associate to the different water requirements, occurs a space variation of the climatic risk to the water required in the State. In analysis of water required in the different phonological stages of the Conilon coffee, it was identified that 58% of the area of the state of Espirito Santo, mainly in the north part, presents high climatic risk of water required in the phases of the flowering, bean formation and vegetative growth.
