Climatic zoning of the Ibero-American viticultural regions

Abstract

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 seventeen viticultural climates in the twenty-six viticultural regions in the nine countries of the project. The identified viticultural climates represent forty-four 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. 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.

Assessing the climate change vulnerability of European winegrowing regions by combining exposure, sensitivity and adaptive capacity indicators

Winegrowing regions recognized as protected designations of origin (PDOs) are closely tied to well defined geographic locations with a specific set of pedoclimatic attributes and strictly regulated by legal specifications. However, climate change is increasingly threatening these regions by changing local conditions and altering winegrowing processes. The vulnerability to these changes is largely heterogenous across different winegrowing regions because it is determined by individual characteristics of each region, including the capacity to adapt to new climatic conditions and the sensitivity to climate change, which depend not only on natural, but also socioeconomic and legal factors. Accurate vulnerability assessments therefore need to combine information about adaptive capacity and climate change sensitivity with projected exposure to new climatic conditions. However, most existing studies focus on specific impacts neglecting important interactions between the different factors that determine climate change vulnerability. Here, we present the first comprehensive vulnerability assessment of European wine PDOs that spatially combines multiple indicators of adaptive capacity and climate change sensitivity with high-resolution climate projections. We found that the climate change vulnerability of PDO areas largely depends on the complex interactions between physical and socioeconomic factors. Homogenous topographic conditions and a narrow varietal spectrum increase climate change vulnerability, while the skills and education of farmers, together with a good economic situation, decrease their vulnerability. Assessments of climate change consequences therefore need to consider multiple variables as well as their interrelations to provide a comprehensive understanding of the expected impacts of climate change on European PDOs. Our results provide the first vulnerability assessment for European winegrowing regions at high spatiotemporal resolution that includes multiple factors related to climate exposure, sensitivity, and adaptive capacity on the level of single winegrowing regions. They will therefore help to identify hot spots of climate change vulnerability among European PDOs and efficiently direct adaptation strategies.

Mesoclimate impact on Tannat in the Atlantic terroir of Uruguay

The study of climate is relevant as an element conditioning the typicity of a product, its quality and sustainability over the years. The grapevine development and growth and the final grape and wine composition are closely related to temperature, while climate components vary at mesoscale according to topography and/or proximity to large bodies of water. The objective of this work is to assess the mesoclimate of the Atlantic region of Uruguay and to determine the effect of topography and the ocean on temperature and consequently on Tannat grapevine behavior.

Bioclimatic shifts and land use options for Viticulture in Portugal

Land use, plays a relevant role in the climatic system. It endows means for agriculture practices thus contributing to the food supply. Since climate and land are closely intertwined through multiple interface processes, climate change may lead to significant impacts in land use. In this study, 1-km observational gridded datasets are used to assess changes in the Köppen–Geiger and Worldwide Bioclimatic (WBCS)
