Abstract

In the West Indies, the climate is favorable for the growth of weeds and monocultures need chemical inputs, which increases the pesticide pressure. In Martinique, pollution by chemical molecules, via spatialized transfer mechanisms at the watershed scale, degrades the quality of river water. In this context, the thesis proposes an original collective design method to design innovative territorial organizations that coordinate changes in agricultural production systems, which reduce the concentration of herbicide in rivers.The approach is applied to a watershed polluted by herbicides and combines: a socio-technical system diagnosis, a phase of innovative design workshops inspired by the CK theory and a phase of evaluation of innovative concepts by simulation in a role-playing game. Innovations involve a spatial distribution of innovative techniques on the territory of the watershed and devices, facilities, organizations to ensure their success and sustainability. The thesis is in the fields of Landscape Agronomy and Innovative Design Agronomy.
