L’irrigation en Beauce, un facteur de production créateur de richesse. AGTE Centre - Analyses et Résultats Numéro 2012AR54

Fiche techniqueAvec plus de 340 000 ha de surface potentiellement irrigable, la Beauce est comparable aux grandes régions françaises d’irrigation. Elle devance les régions Aquitaine (302 000 ha) et Midi-Pyrénées (290 000 ha). Les deux tiers des surfaces agricoles sont équipées dans la Beauce de la région Centre (311 000 ha) alors que seul le tiers l’est dans celle d’Ile-de-France (32 000 ha). Deux départements, le Loiret et l’Eure-et-Loir, totalisent 79 % de la surface irrigable en Beauce.Les 241 000 ha irrigués en 2010 se situent à 92 % en région Centre

France

International audienceThe development of irrigation in France is several centuries old. During the twentieth century the state constructed most of the irrigation networks. Individual irrigation development dates back to the 1960s and is characterized by an easier uptake of technological innovations. Today, the total equipped area is leveling off, and trends include a development of drip irrigation and the near disappearance of gravity irrigation. Public policies with a direct or indirect impact on irrigation have also changed significantly in recent decades. Agricultural policies, once very favorable to the development of irrigation, have moved to policies that are increasingly oriented toward the protection of water resources. In some basins, farmers face severe administrative reduction of their pumping authorization. Water resources management at the watershed or territory levels also changed significantly. In basins facing large quantitative deficits, special institutions are created to manage the volume of water available for agriculture. However, concerns remain regarding the effectiveness of such institutions and more generally the future of irrigation in a context of global change

ACTIVAGE - Report on IoT devices

In order to have a complete Architecture of the ACTIVAGE platform, the device domain constituted of smart sensor and actuator nodes, gateways, connectivity and its associated protocols must be also considered. Therefore, it is imperative to identify the different devices required to implement the uses cases considered in the different Deployment sites (DSes). A systematic analysis is performed on the device, gateway, cloud and applications domains constituting each of the nine DSes. This analysis is based on several registration forms in order to gather key elements of each domain. The original goal was to collect information concerning only the device domain. However during the first months of the project, this goal changed to also include the three other domains in order to get an overall, homogenized, and rich technical information view of each DS. The additional information includes, the DS topology, the applications foreseen, the security and privacy mechanism to be implemented in the overall system, the servers used and their locations, and other information required to facilitate, in Task 3.2, the Security and Privacy assessments. Furthermore, this document gives a summary and classification of the different devices used in each DS allowing the identification of communalities, potential synergies and knowledge sharing between DSs. For the cases where, no suitable solutions are available, new devices could be prototyped in order to support a given use case with the right device or the right security protection level. Finally and in order to have a more complete document, the following aspects are also included: a list of key concepts in the device and gateway domains are explicitly defined to be shared and used in the overall project, a short introduction on the evolution of the communication systems is given in order to understand key IoT concepts at IoT architecture level and in particular at the device and gateway domains, including some security ones, and a brief market analysis on the home automation and health care devices

ACTIVAGE - D9.6 Final results report & sustainability plan (I to IX)

We have reached the end of a challenging and rewarding journey, after 45 months of ACTIVAGE, this is the last report that aims at providing a taste of the huge work done by the teams at the local sites. This is a testimony of the more than 45 partners that have participated in this WP. We started with 9 DS in 7 countries and we finish with 12 DS in 9 countries, having incorporated three new DS through the open call, and expanding ACTIVAGE vision and ecosystem to Portugal and Bulgaria. We have been able to reach the target of deploying AHA-IoT solutions for more than 7.200 users, we hit the mark of 7.776 and almost 97% of the expected deployments. All DS have been able to perform the evaluation, at local and global level, generating the evidence that ACTIVAGE vision is pertinent, relevant, and effective. Details are provided in the individual results and in D6.5. By the end of the project, still 80% of participants continue operation, and almost all DS have in place sustainability plans to continue providing ACTIVAGE services in one way or another. Even in the cases where no clear plans have been possible, there are opportunities for exploiting the services and the knowledge gained in the project
