“…Common agricultural databases—such as the farm accountancy data network in Europe—usually provide input expenditure at the farm scale and not per crop. This explains why the Meuse database has been used by many studies on French agriculture (e.g., Bareille & Letort, 2018; Boussemart et al, 2011; Carpentier & Letort, 2012; Chakir & Thomas, 2022; Femenia & Letort, 2016; Koutchadé et al, 2018).…”

A large literature has assessed the impacts of climate change on agricultural production by estimating reduced‐form models of crop yields conditionally on weather and individual fixed effects. The estimates obtained are usually interpreted as the weather impacts on yields once farmers have adapted. Yet, few attempts have documented that farmers do adapt to weather, and none have verified that these adjustments actually impact crop yields. Our objective here is to unpack how weather affects agricultural production by developing a structural model that explicitly accounts for both the plants' biophysical and farmers' behavioral responses to weather. Considering adaptation during the growing season through fertilizer and pesticide applications, our approach allows us to distinguish the “direct” weather effects (i.e., the agronomic impacts of weather changes on plant growth per se) from the “indirect” weather effects via farmers' input choices (i.e., the adaptation impacts). We estimate the underlying structural model using farm‐level data from the Meuse French department, which provides details of fertilizer and pesticide uses by crop. We show that the reduced‐form and structural estimates indicate similar weather impacts on crop yields, for a large range of sensitivity analyses. Our structural estimates indicate that the adaptation effects are sizable and that farmers' adjustments reduce projected damage from climate change. In our illustrative case, farmers' adaptation offsets between one‐quarter to two‐thirds of the negative agronomic impacts of future warming on crop yields. Our analyses exhibit that commonly used reduced‐form models of crop yields inherently capture these within‐season behavioral responses to weather.

Many countries have implemented policies to reduce the use of chemical inputs in agriculture. However, these policies face many obstacles that limit their effectiveness. The purpose of this paper is to review the main challenges associated with reducing chemical inputs in agriculture and to propose potential solutions. Our analysis, based on a literature review linking agronomy and economics, shows that several agronomic options have proven effective in reducing chemical inputs or mitigating their negative impacts. We argue that the organization of the agri-food system itself is a major barrier to their implementation. Involving all stakeholders, from the chemical input industry to consumers, and designing appropriate policy frameworks are key to address this issue. We recommend combining different policy instruments, such as standards, taxes and subsidies, in a simplified and coherent way to increase effectiveness and ensure better coordination in the adoption of sustainable practices.
