Fractal analysis of the hydrological information obtained from high-spatial resolution dems: application in terroir zoning of d.o. campo de Borja (Spain)

Abstract

One of the characteristics of the terroir zoning studies that is more complex to manage is the scale dependence. Thus, terroir zoning studies of the same area at different scales are comparable but not equal. Fractal analysis has demonstrated to be a suitable tool to characterize and model natural elements within a defined range of scales. 

Nowadays, the fast evolution of the GISs and the availability of high-resolution topographic information allow to carry out studies considered unthinkable some decades ago. 

Parallelism between the elements which condition the drainage networks of a landscape, and the elements which define the terroir has been observed. It is well known by geomorphologists that the shape of the drainage networks (dendritic, parallel, radial, etc.) depends on natural factors such as climate, vegetation and geological characteristics, particularly lithology and structure, which also characterize the terroir of a region. 

The main objectives of the present study are the quantitative characterization, using techniques of fractal analysis, of the drainage networks of the D.O. Campo de Borja, and the analysis of its relationship with the vineyard distribution within the region. The studied drainage networks have been extracted from a DEM with a resolution of 5 meters. 

The results show the suitability of the study and encourage to deepen into the relationship between the drainage networks crossing the landscape, the geological and topographic characteristics of the environment, and the distribution of the vineyard within the region.

Barrels ad-hoc: Spanish oak wood classification by NIRs 

The wooden barrel is a key factor in enology, since wine chemical composition and sensory properties changes significantly in contact with the barrel[1]. Today’s highly competitive market constantly demands new differentiated products and wineries search innovations continuously.
Wood selection is crucial: barrels stability to keep constant their contribution and the result on products, and additional and differentiated wood contributions to impact their new products. Oak wood selection has traditionally been carried out using parameters such as specie, location and grain, however, it goes one step further nowadays. Large cooperage work with non-destructive techniques that allow classifying oak wood quickly and easily according to their organoleptic contribution[2].

Integrative study of Vitis biodiversity for next-generation breeding of grapevine rootstocks 

Drought is one of the main challenges for viticulture in the context of global change. The choice of rootstock could be leveraged for vineyard adaptation to drought as we can improve plant performance without modifying the scion variety. However, most of the existing rootstocks, selected over a century ago, have a narrow genetic background which could compromise their adaptive potential.

Settling precocity and growth kinetics of the primary leaf area: two indicative parameters of grapevine behaviour

Le comportement de la vigne en terme de fonctionnement thermique et hydrique, influe de manière directe sur la qualité des baies de raisin. L’effet du terroir peut être perçu à travers l’étude de paramètres tels que la précocité, la mise en place de la surface foliaire ou la vigueur. Une expérimentation a été conduite en Val de Loire sur le cépage chenin dans le but de mieux comprendre le rôle des variables liées au terroir sur la croissance et le développement de la vigne et in fine sur la qualité des baies.
