High resolution remote sensing for mapping intra-block vine vigour heterogeneity

Abstract

In vineyard management, the block is considered today as the technical work unit. However, considerable variability can exist inside a block with regard to physiological parameters, such as vigour, particularly because of soil heterogeneity. To represent this variability spatially, many measurements have to be taken, which is costly in both time and money. High resolution remote sensing appears to be an efficient tool for mapping intra-block heterogeneity. A vegetation index, the Normalized Difference Vegetative Index (NDVI), calculated with red and near infrared leaf reflectance can be used as a vine vigour indicator. Because of the cultivation of vines in rows, a specific image treatment is needed. Only high resolution remote sensing (pixels less than 20 cm per side) allows the discrimination between row pixels and inter-row ones. The significant correlation between NDVI and pruning weight and the possibility to map the vigour with the NDVI by means of high resolution remote sensing, show the ability of NDVI to assess intra-block variations of vine vigour.

Irrigation and terroir: two opposite concepts? Point of view of international experts and french consumers

At long term, qualitative irrigation seems to be the most systematic, if not the best, cultural practice for dealing with climate change and yield increases without decrease grape quality.

Physiological response to drought and heat stress in the leaves of table grape varieties

Increasingly pronounced climate changes, including prolonged drought periods, pose a significant challenge to the cultivation of table grape varieties.

Bacterial community in different wine appellations – biotic and abiotic interaction in grape berry and its impact on Botrytis cinerea development

An in-depth knowledge on the conditions that trigger Botrytis disease and the microbial community associated with the susceptibility/resistance to it could led to the anticipation and response to the Botrytis emergence and severity. Therefore, the present study pretends to establish links between biotic and abiotic factors and the presence/abundance of B. cinerea.

Enhancing vineyard resilience: evaluating sustainable practices in the Douro demarcated region

In mediterranean agriculture, sustainability and productivity are seriously threatened by climate change and water scarcity. This situation is exacerbated by poor management practices such as excessive use of agrochemicals, overgrazing, and monoculture. The Douro demarcated region (ddr) is an emblematic region, classified world heritage site by UNESCO in 2001. Viticulture is the main agricultural activity in DDR, widely known to produce port wine.
