Abstract: A geospatial analysis of climate variability and change pattern of the study area was conducted in this study. It entailed mapping of the location and areal extent, relief and drainage, climate, geology, hydrogeology, soil and vegetation, population/settlement and socio-economic activities. The mapping of the geographic variables was conducted to ascertain the level of socio-economic development of the region as climate variability and change pose a critical threat to global socio-economic development. The evaluation of climate variability and change pattern involved analysis of climatic data documentation of the Nigerian Meteorological Agency (NIMET), Calabar Station that span 43 years (1971–2014) of the study area and compared against NIMET's historical meteorological data maps of Nigeria between 1941-1970 and 1971-2000, otherwise called the base period to ascertain the status of climate variability and change. The comparison revealed a historical sequential rise in temperature, evidenced by late onset and early cessation of the rains. The late onset and early cessation of rains has necessitated the contraction of the length of the rainy season. This has impacted negatively on farming practices in the region. There is also evidence of significant changes in known weather patterns in the region. For example, the little dry season, then commonly August Break has become less significant in the region. Similarly, the analysis has revealed that the environment has become warmer as temperatures have risen considerably and harmattan dust haze has also become more pronounced in recent years. The mapping and evaluation of Calabar river basin was necessitated owing to its distinct socio-economic benefit to Nigeria and Africa. The region plays host to Africa's foremost leisure resort (Tinapa), one of world's largest rubber plantations (Pamol), the National Integrated Power Project (NIPP), Nigerian Police Training School etc.
