Context

Structuring a system to reconcile sustainable agriculture and water quality

AgriParisSeine is a territorial cooperation consortium aimed at supporting the Nourishing Seine Project, which is backed by the Bank of Territories.

The need was for a study aimed at structuring sustainable agricultural and food sectors in the Seine basin. It focused on creating a system that protects water resources while promoting sustainable sectors, as well as supporting partners to co-construct a common territorial system.

Indeed, the Seine Basin area is facing a major environmental challenge regarding water resources, which are experiencing significant rates of diffuse pollution (pesticides, nitrates), as well as an agricultural challenge that combines fair compensation for producers, resource protection, and the development of sustainable sectors.

A multi-stakeholder co-construction to design a PES system

Vertigo Lab has identified and analyzed socio-economic mechanisms that promote agricultural practices preserving water resource quality, and then organized multi-stakeholder working sessions to co-construct the PES mechanism.

We supported the drafting of an action sheet for the preliminary design of a PES in the territory of Agri Paris Seine members, including a definition of the PES framework (PES objectives, targeted territory, targeted farmers, governance, necessary human and financial resources), the development of evaluation indicators (for inputs and results) and the creation of a financial model and a global timeline.

BENEFITS

An operational framework to deploy an environmental system

The mission defined the framework for the PES, including objectives, targets, and human and financial resources, as well as constructing an action sheet for the prefiguration of the system. It also allowed for the development of monitoring and evaluation indicators, as well as providing support for seeking co-financing.

The + Vertigo Lab

Experience and theoretical and practical expertise in PES were mobilized, with facilitation of partnership reflections and co-construction working sessions.
