Irrigation with saline water is practiced in countries prone to water scarcity, in arid and semi-arid climates. In a Mediterranean climate (Sicily, southern Italy), transpiration and canopy resistance were determined in a vineyard (Syrah grafted on Paulsen 1103) irrigated with water at two salinity levels. One section of the experimental plot was i...

Climate evolution may lead to changes in the amount and distribution of precipitations and to reduced water availability, with constraints on the cultivation of some crops. Recently, foreseen crop responses to climate change raise a crucial question for the agricultural stakeholders: are the current production systems resilient to this change? An a...
Conference Paper
Full-text available
Crop production depends significantly on the pedoclimatic conditions. The evolution of climate may thus endanger not only yield (IPCC, 2007), but, more significantly, the sustainability of the cultivation of current varieties. Adaptation of current production systems may be feasible, but requires a timely evaluation of weather adaptation to climate...

The intra-specific biodiversity of agricultural crops is very significant and likely to provide the single major opportunity to cope with the effects of the changing climate on agricultural ecosystems. Assessment of adaptive capacity must rely on quantitative descriptions of plant responses to environmental factors (e.g. soil water availability, te...
Presentation
Full-text available
The lack of information about air temperature (Ta) spatial distribution is a central problem in agro-environmental studies at all scales. Air temperature is in fact the most important variable, along with radiation, to influence crop development and its spatial distribution. It is used as input in a large variety of models ranging from prediction o...
Poster
Full-text available
Future climate scenarios predict substantial changes in air temperature within a few decades and agriculture needs to increase the capacity of adaptation both by changing spatial distribution of crops and shifting timing of management. In this context the prediction of future behaviour of crops with respect to present climate could be useful for fa...
Poster
The adaptation of agricultural species needs to be evaluated against model-generated climate scenarios. Adaptation strategies, contrary to mitigation, are strongly related to the spatial variability of environmental conditions,being dependent on local and different vulnerability conditions of the territory. In this context we have evaluated the sta...

Coratina) grove in Andria, southern Italy, and (2) to compare different methods for estimating leaf area distributions. Stand biometry was represented by a stocking density of 132 trees ha-1, mean spacing of 8.7 m and mean social ar...
Presentation
Simulation models can improve crop management and estimation of crop performances under water-limited conditions. Crop transpiration and soil water balance can be described by Soil-Plant-Atmosphere Continuum (SPAC) numerical models and for reliable simulations there is a need for a correct parameterization. Root water uptake is often modelled by m...

Project
To improve farm and irrigation district water use efficiency and farm profitability by developing an operational management system (Web-Gis System). The SMARTIES system will be designed to be used: i) in real time mode, during the irrigation season, to support irrigation strategy for weekly and seasonal forecast; ii) in an off line mode, before the irrigation season, as in interactive simulator of irrigation and crop yield strategy under seasonal forecast conditions. The WG System will be sustained by several tools designed pixel-wise as: numerical soil moisture energy - water balance models, crop model, assimilation of satellite data, daily to seasonal weather forecast. The system will be tested in six case studies across Southern Europe and North Africa including Italy, Spain, Morocco, Tunisia and Egypt. The project will be carried out by 13 partners (8 from European Union and 5 from North Africa) FINANCIAL SUPPORT - Miur PROJECT LEADER - Marco Mancini, Politecnico di Milano PI of CNR-ISAFOM - Francesca De Lorenzi www.smarties.polimi.it
