# Pesticide-free agriculture needs a systemic and collective approach

To meet the challenges of agroecology and zero pesticide, we need to design innovations at a territory level

## A local charter : No use of pesticides - 2040

## A typical agricultural territory for the "Grand Ouest"

### A water catchment

* 105 farms (92% with livestock)

* 5,800 ha of Utilised Agricultural Area (UAA)

* 25 organic farms (20% of UAA)

## SUPPORT

<figure><img src="image_43.png" /></figure>

* Methods

* Socio technical diagnosis (Casagrande et al., 2024, IFSA)

* Innovation tracking (Salembier et al., 2021)

* Tools

* Tools for scenarisation : Co-Click'Eau (Chantre et al., 2016), Maelia (Therond et al., 2014)

* Index at territory level to assess pollination (Gandarat PhD)

* RPG explorer (Martin et al., 2016)

* Dashboards (Prost et al., 2018)

* IDEA 4 (Zahm et al., 2024)

* Agroecological Knowledge

* Natural regulation in arable crops

* Collective intelligence process induced by a facilitation role of researchers

## ANALYSE

<figure><img src="image_44.png" /></figure>

* Process of design

* Strategies to move towards pesticide free T : the systemic nature of the ongoing processes

* Several way to assess the territories issues

See presentation of Rosan De Lange

<figure><img src="image_45.png" /></figure>

* Dynamic of change in territories

* Longitudinal analysis of the design dynamics and changes taking place in the territories fed by trimestrial follow-ups with each case study

* Agroecology process in the field

* CHARACTERISING

* the influence of practices on the dynamics of crop auxiliaries

* The influence of landscape practices on pollination index

My question to introduce the discussion

The role of the researcher in such complex project is often matter of debate in
our team.

*What experiences would you like to share where the role of the agronomic researcher and their impact have been questioned?*
