Comparison between energy balance and mass balance models for actual evapotranspiration assessment

2009

The assessment of the water needs for a specific crop has a fundamental importance in the management of water resources. The application of empirical models able to retrieve estimates of the actual evapotranspiration (ETa) to assess the need for water could give a valid tool for the planning of water supply, avoiding unnecessary water losses. In this context, two independent models for estimating actual evapotranspiration were compared. The first model is based on an energy balance and uses remotely sensed data and ancillary data from weather stations to assess the ETa. The second model also uses remotely sensed data and climatic data on a daily basis from a weather network. Field measureme…

Sustainability initiatives and experiences in the Sicilian wine industry

2016

The Italian wine sector shows an increasing interest towards sustainability issues. As a result, a wide number of programs and initiatives concerning environmental, social and economic sustainability has been developed in recent years. The aim of this manuscript is to describe the adaptation of the Sicilian wine sector to the new scenario of sustainable productions. To this purpose a direct survey of 5 Sicilian wineries involved in two different sustainability programs, SOStain and Magis, was carried out. The findings of the study reveal that the sustainability path undertaken by the wineries analyzed has led to management awareness that company activities can ensure social and human benefi…

Competitiveness and sustainability of extreme viticulture in Pantelleria Island

2011

The environmental and land protection could be obtained promoting an agricultural activity that encourages the business competitiveness respecting the traditions. In Pantelleria, ‘black island’ in the middle of Mediterranean, the viticultural surface has significantly decreased in the last years, causing a massive rural exodus. The University of Palermo, to block this phenomenon and to contain the progressive abandonment of vineyards, carried out several experimental proofs in order to increase the mechanization of cultural practices in the vineyards cultivated according to ‘alberello a conca’ farming system. In this context, the aim of this paper is to analyze as the process innovations co…

Table-Grape Cultivation in Soil-Less Systems: A Review

2022

Table grape (Vitis vinifera L.) is considered to be one of the most popular fruit crops in the world. Italy is the leading table-grape producer in the EU and is the main European exporting country. However, to stay competitive, new solutions and perspectives, including varietal renovation, are now needed in addition to the already well-established Italian table-grape production lines consisting of conventional open-field cultivation and greenhouse cultivation. One of these new perspectives is represented by the development of table-grape soil-less cultivation systems (TGSC) under greenhouse. In fact, TGSC systems are alleged to offer many advantages in terms of the advancement of berry matu…

Integrated Protection in Viticulture

2008

Presentazione convegno

2022

The idea behind this Conference is to promote and disseminate legal and digital forms capable of making "sustainability" mandatory: and on the other hand to really achieve the climate objectives that would like to eliminate CO2 emissions and the land consumption by 2050, adherence to disciplinary leads to sustainability mindsets cannot be left to the "conscience" of entrepreneurs but should switch from incentivized forms of coercion or negotiation also with the use of already tested tools such as those of collective autonomy.

Assessment of vineyard vigour and yield spatio-temporal variability based on UAV high resolution multispectral images

2023

Accurate, timely assessment of the vineyard on a field scale is essential for successful grape yield and quality. Remote sensing can be an effective and useful monitoring tool, as data from sensors on board Unmanned Aerial Vehicles (UAV) can measure vegetative and reproductive growth and thus directly or indirectly detect variability. Through the images obtained from UAV, the Vegetation Indices (VIs) can be calculated and compared with various agronomic characteristics of the vineyard. The objective of this study was to evaluate the multispectral response of the vineyard in three specific phenological phases and to analyse the spatial distribution of vegetative vigour. A multirotor UAV equi…

Climat et viticulture au Vietnam : évaluation et perspectives

2009

International audience; Parmi les activités humaines, la culture de la vigne pour la production de vin est fortement dépendante des conditions climatiques. Le potentiel d'une zone viticole est sous l'étroite influence du climat, en particulier des conditions radiatives, thermiques et hydriques, de telle sorte que la plupart des vignobles à caractère œnologique sont localisés aux latitudes moyennes. Pourtant, l'expansion de la viti-viniculture aux basses latitudes s'est accélérée ces dernières années. Ici, les conditions climatiques et la faible variation de longueur des jours permettent dans la plupart des cas deux à trois récoltes par an, alors qu'une seule n'est envisageable dans les régi…

The communicative power of an extreme territory – the Italian island of Pantelleria and its passito wine

2018

Purpose This paper aims to examine how Pantelleria’s wineries communicate the extreme territory of Pantelleria through its passito wine and whether this may be a value added for consumers. Specifically examines which dimensions of communication are effectively used by wineries to stimulate, in wine consumers, emotions that link passito wine with the territory of Pantelleria. Design/methodology/approach All websites of wineries producing passito wine in Pantelleria were analyzed using the adaptation, goal-attainment, integration and latent pattern maintenance (AGIL) scheme for measuring communication dimensions. Findings Results suggest that wineries and stakeholders should apply territory-…

Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case …

2017

The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. We studied YLOID (Y, La and lanthanoids), recognized as very useful tracers due their coherent and predictable behavior, to trace and evaluate their distribution from soil to the grape in Vitis vinifera L. Because much of the world’s viticulture is based on grafting, and rootstocks have proved affect vine growth, yield, fruit and wine quality, we carried out experimental trials to analyse the YLOID distribution of two different red cultivars, grafted onto six different rootstocks, on the same soil. The YLOID amounts, the relationship Heavy vs Ligh…
