    ABSTRACT ThisstudyexaminestheroleofAgriculture-drivendeforestationininfluencingclimate variability, perceptions and experiences among smallholder farmers in Ogun State, Nigeria. With increasing land-usechangesattributed toagricultural expansion.thestudyaimstoassessthe nexusbetweenforestclearingandlocalizedclimatevariations.Primarydatawerecollected throughstructuredquestionnairesadrñinisteredto200respondentsselectedthroughmultistage sampling.Thedatawereobtainedontherespondentssocio-economiccharacteristics,adaptation strategies initiated against agriculture-driven deforestationand awareness ofclimate variability whilesatelliteimagerybetweenyear2013and2023wascollected toassessthepatternofland use and land cover changes (LULC) and to determine the effects of agriculture driven deforestationon climate variability with afocuson changes in temperatureand carbon dioxide.

The major adaptation strategies initiated against agriculture-driven deforestation were agroforestry (x —4.00), awareness/education (I = 4.00), and paying farmers to conserve ecosystem(x=3.95).LULCstatisticsshowsthatwaterbodyincreasedfrom82Km2to 90.03Kiu2,vegetationcover decreased from 1l,618Km2 to 9,720.24Km2, developed area increasedfrom507.42km2to1,443.7km2whileagriculturalland increased from4,476Km°to 4,922.02Kni2between2013and2023respectively.Thetemperaturerangebetween2013and 2023wasslightlylower,temperaturedecreasedwithincreaseinvegetationcoverovertheyears atabout61%relationships,therewasasimilarnegativerelationship between vegetationcover and carbon dioxide concentration at 84%. Logistic regressionmodel shows that income (§= 1.000 p<0.10), practice preferred (§= 1.653, p<0.10) and land ownership (b=0.558, p<0.05) negativelyinfluencedawareness ofclimate variability while non-farmincome (§=l.000, p<0.01) positively influenced awareness of climate variability. The study concludes that unchecked agriculture-induced deforestationexacerbatesclimate variabilityin Ogun State leading to temperature variations, lossofstored carbon ascarbon dioxide intotheatmosphere and increased greenhouse gas emissions resulting in global warming, the assessment revealed that without secured land, farmers focused on short-term gains, rather than long-term sustainability, they overexploitednatural resourcesleading toescalated deforestation,soil degradation and lossof biodiversity.
