Early warning systems that make use of agrometerological forecasts are one of the coping strategies developed by policy makers. However, the predictive quality of the tools and methods used needs improvement. In order to address some of these challenges, we conducted agronomic trials and on-farm surveys to adapt the SARRAH (Systeme d'Analyse Regionale des Risques Agroclimatiques, version H) crop simulation model, and also evaluated it in farmers' field conditions. The farmers' practices such as sowing dates and densities, fertilizer use and yields potentials of the millet and sorghum crops were characterized under different climatic conditions. specialized climate impact agriculture West Africa farmer practices sorghum millet 072 Monsoon Multidisciplinary Analysis (AMMA) : an integrated project for understanding of the West African climate system and its human dimension Atmospheric Science Letters 12 1 89-95 2011 1530-261X https://www.documentation.ird.fr/hor/fdi:010053174 10.1002/asl.295 1530-261X [F B010053174] https://www.documentation.ird.fr/hor/fdi:010053174 https://www.documentation.ird.fr/intranet/publi/2011/03/010053174.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2011-04-07 2017-08-23 fdi:010053174 fre
