ABSTRACT: Current climate change trends are leading to the emergence of meteorological and climatic risks for agriculture. To better understand these risks, it is essential to analyse current trends in meteorological and agro-meteorological indicators. This study examines the variability of these indicators in the Faranah region in order to understand local climate dynamics and assess their implications for the agro-climatic system. The assessment of agroclimatic resources is based mainly on the sum of active temperatures (STA), Selyaninov’s hydrothermal coefficient (GTK) and the standardised precipitation index (SPI). The study highlights annual and interannual variations and current trends in temperature, rainfall anomalies and agroclimatic indices. Three phases appear between 1994 and 2024: wet (1994-2000), dry (2001-2007) and unstable (2007-2024). The sum of active temperatures remains stable overall, except between 2001 and 2008. These dynamics reflect the impact of climate change, accentuated by human activity, and highlight the urgent need for agroclimatic adaptations.
