| The Ibero-American Network of Viticulture, a component of the program of agricultural technology of the CYTED (Ibero-American Program of Science and Technology for Development), is developing the project ¿Zoning Methodology and Application in Viticultural Regions of Ibero-America¿. An objective of the project is the climatic characterization of this large viticultural region with the participation of ten countries: Argentine, Bolivia, Brazil, Chile, Cuba, Spain, Mexico, Peru, Portugal, and Uruguay. The first step in the research is based on Systematic Multi-criteria Climatic Classification (CCM) for Geo-viticultral regions. The project has assembled a climatic database that characterises the viticultural regions that includes variables relevant to viticulture: air temperature (average, maximum, and mininmum), precipitation, relative humidity, solar radiation, number of sunshine hours, wind speed, and evapotranspiration. The application of the climatic indices IH, IF, and IS of the CCM System, highlights the variability of the thermal and hydrological components of the viticultural climate. The analysis of the climatic database, show the large climatic variability of the region. The initial results have identified twenty three viticultural climates in the ninety-two viticultural regions in the ten countries of the project. The identified viticultural climates represent sixty percent of the climatic groups identified at the global level. This large regional climatic variability explains, to a large extent, the large diversity in the products of the Ibero-America region, including the organolepctic characteristics and the uniqueness of the vines produced. The research has also highlighted viticultural areas characterised by large inter-annual climatic variability. In such areas, the viticultural climatic classification changes as a function of the time of the year where grape-wine can be produced. A book is going to be published to spread the results of the climate zoning at it will be ready in short time.The undergoing climate zoning is going to be used is a second phase of the project as a component of an integrated study that includes regional edaphic factors, and indicators of ecophysiological responses of the vineyards to natural factors | |
