Master of Science Internship – Towards a better inclusion of biodiversity in global food systems models

The first objective of this internship is to perform a systematic literature review of available global food system models. An expected outcome of this work is to identify/propose possible ways of including biodiversity in global food system models in such a way that feedback loops between biodiversity and agricultural production are captured.

Master of Science Internship – Relationships between agronomic practices/systems and biodiversity at the global scale

The first objective of the internship is to reference the existing databases on biodiversity as well as agronomic practices/systems at the global scale. A second objective is to perform an analysis of their level of overlap to define the potential of their joint analysis. Finally, based on a subset of this former work, a correlative analysis between agricultural practices and biodiversity could be engaged with regard of the interest of the student.

Unravelling the step-by-step process for farming system design to support agroecological transition

Given the huge challenges agriculture has to face, both in Northern and Southern countries, a radical change in farming practices towards agroecology is required. Most scientific literature on the design of new farming systems describes de novo approaches, which focus on disruption and novelty, without any concern for the way to move from the current system to the innovative one. In this study, we highlight, for the first time, the particular traits of what we will call the step-by-step design approach.

Climate Change Explorer, an interactive map to understand the future global climate

It can be difficult to imagine the impact of climate change on our lives and in particular on local cultivated vegetation. Based on the results of the climate models used by the IPCC for its reports, we propose a visualization of the expected evolutions of local climates according to global greenhouse gas emission scenarios. These evolutions are compared to the climates found in the world between 1970 and 2000 to identify current climate analogues to future climates: in order to represent the future climate of a considered place, we look for places on the planet whose current climate is similar to this projected climate.

Residents' exposure to pesticides: how close are agricultural areas to residential buildings in France?

In a decree issued in 2019, the French government defined mandatory pesticide-free buffer zones near residential buildings in order to limit the exposure of residents to pesticides. However, the amount of agricultural area and the crop species grown close to residential buildings had never been studied before in France. This knowledge gap has recently been filled by a team of researchers and teacher-researchers from our lab (UMR Agronomie). They show the amount of agricultural area and crop types within pesticide-free buffer zones around residential buildings vary greatly depending on agricultural regions and the size of buffer zones.

The role of birds in the regulation of insects in arable crops

In arable crops, birds often occupy the highest position in the food chain, feeding on pests (phytophagous insects that attack crops) and their intermediate predators, mainly insects and other arthropods (such as spiders), that feed on these pests. The effects of bird predation on insect pest populations are difficult to estimate without a complete description of prey-predator communities and their complex interactions.

A diversity of On-Farm Experimentation practices and associated farmer-researcher relationships

Experimentation conducted by or with agronomists on farmers' farms is not a fixed methodology, and even less a one-size-fits-all one. There is a wide diversity of ways of implementing experimental protocols, carrying out monitoring and evaluation, and making use of the results. This article proposes an analysis of this diversity via a review of the scientific literature and the identification of 7 types of on-farm experimentation practices.

Effects of landscape characteristics on crop pests

Landscape management is often seen as one of the levers to be used to improve pest management. However, the complexity of interactions makes it difficult to establish general rules, and, depending on the pests studied, landscape elements can have opposite effects, which have been reported in numerous scientific publications. In this study we link French epidemiological surveillance data for 30 of the main pests of French field crops with national maps of tree and field crop areas.
