| ABSTRACT | Mutalemba Ntole romain1, Jean Berckmas Muhigwa2, Espoir Mukengere Bagula1 The world is facing several major challenges that the answer to the current economic crisis and the development of appropriate strategies to mitigate the adverse effects of climate change. The objective of the study is to identify climate risks for maize and the development of an agricultural calendar from a global circulation model of the atmosphere. From meteorological data, an agro-climatic analysis was performed on the 1995-2013 periods and a forecast from 2015 to 2045. Using the cropwater model, variable rainfall and temperature as well as the key parameters of the agricultural season which start and dates, the length of the season and meeting the water needs were analyzed terms of risk of occurrence. The results showed that corn is facing major agro-climatic risks from the shortening of the vegetative growth period consecutive to a screeching halt rains before the end of the rainy season is one of the major agro-climatic constraints. From predicting Sham Gate-5 model the agricultural calendar was adjusted to avoid the drop in rainfall observed in October and plan the sowing period at the end of October instead of September.
