Topographic modeling with GIS at Serra Gaúcha, Brazil: elements to study viticultural terroir

Abstract

Brazil is historically known at the international wine market as an importer, eventhough in the last decades there was an increase in quantity and quality of the internal production. Nowadays, about 40% of fine wines comsuption of the country are national ones. The main production region is called Serra Gaúcha, where the natural conditions are heterogeneous and viticulture is develloped in small properties, mainly done by the owners family. With the strong competition in internal and external market, there is a need to search distinct products in characteristic and typicality. In this context, the concept of terroir is important to drive an to match the grape variety and the cultural practices to the natural potential of each place. This work aim s to study the topographical components of the terroir at Serra Gaúcha using GIS. The study was based on a digital terrain model derived from 20 topographical map sheets in scale 1:50,000. The topographical variables analized were elevation, slope and aspect. Each variable was scores according to its suitability and integrated later on to generate topographical suitability map. The results show that 66% of the area has medium and 9% has high topographical suitability for grapes growth.

Where the sky is no limit — The transformation of wine marketing through text-to-video generation AI model

The introduction of ai-driven tools in digital content creation represents a significant shift in the landscape of marketing, particularly for industries reliant on rich visual storytelling such as the wine sector. The development of ai models like openai’s sora, runway’s gen-2 or google’s lumiere, which can generate realistic video content from textual descriptions, offers promising new avenues for enhancing brand narrative and consumer engagement. This research explores the potential of text-to-video (t2v) ai models to revolutionize wine marketing by creating dynamic, engaging content that captures the essence of vineyards and their products without the need for traditional video production processes.

Conversion to mechanical management in vineyards maintains fruit

Current environmental, ecological and economic issues require a better vineyard production management. In fact, a poor use of fertilizing could lead to harmful impact on environment. Another issue concerns the cultures themselves which couldn’t use fertilizers efficiently, leading to a loss of income or too much expense for farmers. Presently, estimation of fertilization’s needs is realized by the laboratory analysis of leaves selected through a random sampling. The present study aims at optimizing fertilization’s management by using a map of biophysical parameters estimated from satellite images.
