Role of landscape diversity for biodiversity conservation in viticulture: life+ biodivine’s results

Abstract

Nowadays biodiversity loss is considered as a prior environmental issue. Agricultural landscapes are particularly concerned, mainly through the specialization and intensification of farming activities which lead, at a larger scale, to landscape simplification. Landscape management would be a good means to halt biodiversity loss, but large-scale studies remain rare. The life+ project BioDiVine aims to understand biodiversity dynamics and promote sustainable conservation actions at this scale in viticulture. 

Seven demonstration sites, in France, Spain and Portugal, followed common protocols in order to quantify biodiversity in vineyard plots and evaluate its possible link with the surrounding landscape. In each area, arthropods were monitored on 25 selected plots, from 2011 to 2013. Arthropods were sampled by non-selective trapping stations set into vines and semi-natural habitats (2011) and exclusively inside vine plots (2012-2013). They were sorted out using the Rapid Biodiversity Assessment method. Then, abundance and richness indices were calculated. The landscape surrounding each trapping station (400m radius) was characterized through a GIS database. Then, indices such as proportion of semi-natural habitats have been calculated. 

Semi-natural habitats show higher arthropods richness than vineyards, with a significant difference in richness values of 20 to 50%, depending on demonstration sites. On all French demonstration sites, a significant positive correlation was shown between the proportion of semi-natural habitats in a 400 m buffer area and the arthropods richness inside the vine plot. These results support the action program of the BioDiVine project, which consists in encouraging landscape management actions such as planting hedgerows or restoring semi-natural elements connectivity. This can be an efficient way to support biodiversity and promote environmental-friendly wine production. Yet, these actions have to be collectively managed to reach their maximum efficiency, and require a huge coordination effort.

Mechanisms involved in the heating of the environment by the aerodynamic action of a wind machine to protect a vineyard against spring frost

One of the main consequences of global warming is the rise of the mean temperature. Thus, the heat summation by the plants begins sooner in the early spring, and by cumulating growing degree-days, phenological development tends to happen earlier. However, spring frost is still a recurrent phenomenon causing serious damages to buds and therefore, threatening the harvests of the winegrowers. The wind machine is a solution to protect fruit crops against spring frost that is increasingly used. It is composed of a 10-m mast with a blowing fan at its peak. By tapping into the strength of the nocturnal thermal inversion, it sweeps the crop by propelling warm air above to the ground. Thus, stratification is momentarily suppressed. Furthermore, the continuous action of the machine, alone or in synergy, or the addition of a heater allow the bud to be bathed in a warmer environment. Also, the punctual action of the tower’s warm gust reaches the bud directly at each rotation period. All these actions allow the bud to continuously warm up, but with different intensities and over a different period. Although there is evidence of the effectiveness of the wind machines, the thermal transfers involved in those mechanisms raise questions about their true nature. Field measurements based on ultrasonic anemometers and fast responding thermocouples complemented by laboratory measurements on a reduced scale model allow to characterize both the airflow produced by the wind machine and the local temperature in its vicinity. Those experiments were realized in the vineyard of Quincy, in the framework of the SICTAG project. In the future paper, we will detail the aeraulic characterization of the wind machine and the thermal effects resulting from it and we will focus on how the wind machine warms up the local atmosphere and enables to reduce the freezing risk.

Effect of irrigation in cover cropping vineyards

Cover cropping in vineyard is a sustainable and alternative soil management system to conventional tillage that is gaining more and more importance among winegrowers and is being promoted, among other organizations, by the European Union through the eco-schemes of the Common Agricultural Policy.
However, the use of cover crops in Mediterranean viticultural environments is conditioned, to a large extent, by the availability of irrigation water which, in a context of global warming like the one we are experiencing, must be adjusted to savings strategies, supplying to the vine only what it needs in each moment.
