Annual cropping systems (SCA)

The unit aims to develop efficient, sustainable cropping systems, specially annual tropical crops (cotton, sugar cane, rain-fed rice), from an economic, social and environmental perspective. It also aims to expand to all systems including cereals and pulses. Researchers bring together scientific fields such as the analysis of interactions between genotypes and the environment, ecophysiology, agronomy, bio-aggressors and technology at the cultivated plot level.

International partnership is mainly developed in Africa, Madagascar and La Réunion.

• Agro ecology and ecological modelling
• Ecophysiology ( focus on rice, cotton, sugar cane)
• Soil science and management
• Integrated pest management / Spatial ecology
• Biometry

Each of its five research teams works on specific topics, namely (1) design and assessment of annual cropping systems; (2) characterization and integrated management of biotic risks for cultivated ecosystems; (3) Elaboration and characterization of quality, technology laboratory, and characterization of natural fibers; (4) multi-level and spatial representationand decision support systems; (5) sustainable rainfed rice based systems in Madagascar.

Fiber technology laboratory (8 staff), to be accredited ISO 17025
