Need to take decisions and make critical day-to-day and long-term planning on farm management (strategic and tactical).
Support have to be relevant, timely, user-friendly to assist and manage crop cultivation. DSS offer scientific-technical tools often developed by multidisciplinary teams to combine to skills and experience.

J. Pretty et al., INTERNATIONAL JOURNAL OF AGRICULTURAL SUSTAINABILITY 8(4), 2010, 219–236
A challenge is how to feed an incomingpopulation of 9 B. To meet the demand withoutsignificant increases in prices, the need is toproduce 70–100% more food, in the light ofgrowing impacts of cc, concerns over energysecurity, and the Millennium Development target of halving world poverty-hunger by 2015.
The goal is no longer simply to maximizeproductivity, but to optimize across a far more complex landscape of production, ruraldevelopment, environmental, social justice and food consumption outcomes.

1: Natural resource inputs: Climate, water, soil nutrition, erosion, biodiversity, ecosystem services and conservation, energy, climate change and resilience
What are the predicted impacts of cc on yield, cropping practices, crop diseases, irrigation…?What approaches can be developed to increase water use efficiency in agriculture and what is the cost-effectiveness of this approaches?
2: Agronomic practice: production systems and technologies, geneticimprovement, P & D management, livestock
How we can accelerate the rate of technological change to propel sustainableproduction? Which approaches to P&D are the most economically and socially sustainable?

3: Agricultural development: networking, solidarity, reciprocity and exchange, farmer participation in technological development.
Farmers involvement enables novel technologies and practices to be learneddirectly, adopted and adapted. Agricultural and agrometeorological extensionservices are vital elements to address needs and provide critical services.
4: Markets and consumption: food supply chain, food standards, LCA, energy, C footprint, environmental impact.
As energy prices rise, how can agriculture increase its efficiency and usefewer inputs to become economically sustainable and environmentallysensitive, yet still feed a growing population?

Good practices for water management
Water saving
• Dry farming• Crop selection and
management• Improvement of efficiency of
irrigation equipments, reductionof losses
• Water balance calculation, agrometeorological support
• Decision Support Systems and Advisories
Re-utilization• Depuration/ phytodepuration• Irrigation using waste water
To save water, there is not a unique solution, but severalstrategies can be usedtogether. The saving mayreach 20-25 %.
What is a "best management practice for water?"A practical, affordable approach to conserving water without sacrificingproductivity, maximizing its use efficiency.

CER is a consortium distributing water and the most important idraulic infrastructure
Founded by local Authorities and from regional reclamationconsortiums
•Through a channel from Po river water is made available over a 3000 Km2
area and the water resources (68m3/s) allow to satisfy the irrigation needs.
•Water is furnished together with the information for its rational and sustainable utilization (IRRINET).
