ReducPol

ReducPol is in The ITAP (Information – Technologies – environmental Analysis – agricultural Processes)  Joint Research Unit (JRU) includes IRSTEA’s TEMO Research Unit (Montpellier Technologies) and the Montpellier Agro Sup Rural Engineering Chair.

The ITAP research unit

For the purpose of building better agricultural equipment for more sustainable practices and environmental services, the ITAP JRU is developing the following scientific and technical databases:

• Information and associated systems: optical sensors (vision, spectrometry) have been developed to characterise agrosystems and environmental processes as well as decision-support systems by creating new indicators for professionals while exploiting land, climatic and professional data to diagnose the condition of agro-ecological systems;
• Technologies: to develop ecotechnologies for sustainable agricultural production. New design methods which integrate environmental constraints have been studied: eco-evaluation, eco-design, integrated design. The ITAP JRU is especially working on equipment to protect and maintain cultures to limit the impact of pesticide-application techniques on health and the environment. It is directing the regional platform entitled "Ecotechnologies for agricultural bioprocesses" and is a reference centre for agricultural spraying;
• Environmental evaluation: the JRU is developing and implementing tools to evaluate environmental and social impacts based on life-cycle analyses with the purpose of perfecting the procedures. It is directing the ELSA Pole ACVistes network.

The ITAP JRU is associated with the UMII “Process Sciences – Food Science” and “Information, Structure, Systems” doctorate programmes. The UMR ITAP is very involved in building industrial relationships and is encouraging the creation of businesses through its MINEA hosting platform.

The JRU is organised along 4 lines of research:

• Environmental evaluation
• Modelling/decision-making
• Optical sensors
• Dispersion fragmentation
