ABSTRACT
Background: The dynamics of occupation of peri-urban spaces constitutes a headache for producers who are already suffering the pangs of intra-seasonal variations. Objective: The objective of this research is to analyze the effects of climatic variability on the dynamics of formerly rural peri-urban spaces in the district of Zinvié in Benin. Methods: The methodology adopted is based on documentary research and field surveys. The analysis of climatological statistics (rainfall, temperature, humidity) over the period 1981-2017 made it possible to characterize climatic trends. Better still, data from the 2005 LANDSAT TM and 2015 OLI-TIRS satellites coupled with agricultural statistics, direct observations and direct interviews made it possible to assess the modes of occupation and the dynamics of the suburban spaces. Results: Research results show that human settlements have increased. Indeed, the analysis of land use maps shows an increase in human settlements which increased from 275.99 ha of the area of the district in 2005 to 417.18 km² in 2015, i.e. a rate of 66.15 % in 10 years. Added to this already bleak picture is the overall downward trend in rainfall totals (with two deficit sub-periods (1981-1986 and 1990-1994) on the one hand and the general upward trend in temperatures with values positive of the order of 0.06°C (for the minima) and of the order of 0.39 (for the maxima) on the other hand.
Key words: Zinvié district, climatic trend, suburban spaces and land use.
