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.

“Q & A” of the european commission for labeling and desalcoholization for wines: european wine “soft-law”?

Recently, the European Commission seems to have inaugurated a new mechanism for regulating the wine sector. Through two communications, articulated in the form of “Questions & Answers”, concerning the new rules for labeling (24.11.2023) and dealcoholization of wine (15.01.2024), the Commission is not simply “explaining” the new rules but, in an approach close to the theory of “Circulaire Normative” established in comparative law, chooses among different interpretations and even adds Praeter Legem constraints.

Radiative and thermal effects on fruit ripening induced by differences in soil colour

One of the intrinsic parts of a vineyard “terroir” is soil type and one of the characteristics of the soil is it’s colour. This can differ widely from bright white, as for some calcareous soils, to red, as in “terra rossa” soils, or black, as in slate soils.

Leaf elemental composition in a replicated hybrid grape progeny grown in distinct climates

The elemental composition (the ionome) of grape leaves is an important indicator of nutritional
health, but its genetic architecture has received limited scientific attention. In this study, we
analyzed the leaf ionome of 131 interspecific F1 hybrid progeny from a Vitis rupestris (♀) X Vitis
riparia (♂) cross. The progeny were replicated in New York, South Dakota, Southwest Missouri ad Central Missouri, and the concentration of 20 elements were measured in their leaves at
three different phenological stages during the growing season. In leaves collected at the apical node at anthesis, elemental concentrations correlated in a consistent manner (p < 0.05) across all four geographic locations. In subsequent phenological stages, elemental ratios in the apical-node leaves remained consistent across the South Dakota and New York sites, but not across the Missouri sites. In leaves collected at the basal and middle nodes, correlations varied greatly across all locations.
