Describing the possible climate changes in France and some examples of their effects on main crops used in livestock systems Inra
Ruget, F.; Moreau, J.C.; Ferrand, M.; Poisson, S.; Gate, P.; Lacroix, B.; Lorgeou, J.; Cloppet, E.; Souverain, F..
The effects of climate change on forage and crop production are an important question for the farmersand more largely for the food security in the world. Estimating the effect of climate change on agriculturalproduction needs the use of two types of tools: a model to estimate changes in national or local climates and another model using climatic data to estimate the effects on vegetation. In this paper, we will mainly present theeffects of climate change on climatic features, the variability of criteria influencing crop production in variousregions of France and some possible effects on crops

STICS: a generic model for the simulation of crops and their water and nitrogen balances. I. Theory and parameterization applied to wheat and corn Inra
Brisson, N.; Mary, B.; Ripoche, D.; Jeuffroy, M.H.; Ruget, F.; Nicoullaud, B.; Gate, P.; Devienne-Barret, F.; Antonioletti, R.; Durr, C.; Richard, G.; Beaudoin, N.; Recous, S.; Tayot, X.; Plenet, D.; Cellier, P.; Machet, J.M.; Meynard, J.M.; Delécolle, R..
STICS est un modèle de culture conçu comme un outil de simulation opérationnel en conditions agricoles. Ses variables de sortie sont relatives à la production, à la fois en quantité et en qualité, et à l’environnement. Ses entrées sont relatives au climat, au sol et au système de culture. STICS est présenté comme un modèle montrant les qualités suivantes : robustesse, facilité d’accès aux données d’entrée, souplesse d’évolution par une présentation modulaire et généricité (facilité d’adaptation à divers types de plantes). Pourtant, il ne s’agit pas d’un modèle entièrement nouveau dans les formalismes utilisés. Ils sont, pour la plupart, issus de modèles existants. Les grands processus simulés sont la croissance et le développement de la culture ainsi que...

Why are wheat yields stagnating in Europe? A comprehensive data analysis for France Inra
Brisson, N.; Gate, P.; Gouache, D.; Charmet, G.; Oury, F.X.; Huard, F..
The last two decades are witnessing a decline in the growth trend of cereal yields in many European countries. The present study analyses yield trends in France using various sources of data: national and regional statistics, scattered trials, results of agroclimatic models using climatic data. Effects in genetic changes through breeding, agronomy and climate are investigated as possible causes. Our results show that genetic progress has not declined but it was partly counteracted, from 1990 on, by climate change which in general is unfavorable to cereal yields in temperate climates because of heat stress during grain filling and drought during stem elongation. We cannot however, from the decade beginning in 2000, rule out agronomic causes, related to...
