# 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).
La Niña is a cold marine current, an unusual climate phenomenon that usually occurs every 2 to 7 years in the equatorial Pacific and especially along the coast of Latin America. It is characterized by the upwelling of oceanic waters from the depth to the surface. These waters are usually highly nutrient-rich. It affects the global circulation of the atmosphere, and its consequences are worldwide: modification of wind patterns, rainfall, the appearance of extreme climate events such as floods, extreme droughts, etc.
El Niño is a warm ocean current (opposite of La Niña) characterized by an increase in ocean surface temperature. It is a large-scale oceanic phenomenon that occurs in the equatorial Pacific with a periodicity of 2 to 5 years. It affects the large-scale global circulation of the atmosphere and the wind regime. El Niño is the warm phase of the coupled ocean/atmosphere phenomenon known as ENSO (El Niño Southern Oscillation).
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, and 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.
