# GLOSSARY
Agricultural Calendar: A decision-making and advisory tool for planning, managing, and monitoring agricultural activities. It presents the types of crops (maize, sorghum, beans, etc.) and agricultural operations (field preparation, planting, maintenance, etc.) in a given agro-ecological zone (Sudano-Sahelian, Guinea High Savannah, Bimodal Rain forest, Western Highlands, and Monomodal Rain forest).
Climate: All meteorological elements and phenomena (temperature, atmospheric pressure, precipitation, wind, etc.), as well as their dynamics in time and space (expressed in seasons) that characterize a given place or a specific geographical area over a long period (at least 30 years, according to the WMO).
Climate Variability: Variations in meteorological parameters (temperature, rainfall, etc.) around an average on seasonal and inter-annual time scales in a given region.
Climate Change: Also known as climate disruption, climate change corresponds to a long-term change (from one decade to one million years) in the statistical parameters (average parameters, variability, etc.) of the Earth's global climate or its various regional climates. These changes may be due to intrinsic earth processes, external influences or more recently, human activities.
Agro-Ecological Zone: A geographical unit defined in terms of climate, geomorphology, soils, and/or vegetation cover and possessing a specific range of potentials and constraints for land use. Cameroon has five agroecological zones, i.e., the Sudano-Sahelian, the Guinea High Savannah, the Bimodal Rain Forest, the Highlands and the Monomodal Rain Forest Zones.
