本研究旨在评估人类生计活动如何影响尼日利亚克罗斯河州北方地区的气候变化和水资源可用性。该论文主要研究了人类生计活动，如为农业扩张而砍伐森林，雕刻和木材，开发非木材森林产品，采砂和错误的农业实践等如何影响森林植被覆盖的消除，这些活动如何影响降雨量的减少以及随后为气候变化铺平道路。这些活动极大地提高了环境温度，协调了周围环境中的碳积累，并减少了研究区域内的降雨量。使用软件和硬件计算机应用程序，包括德国12手持全球定位系统，和综合土地和水信息系统（ILWIS），用于数据收集。研究收集了定量和定性数据。GIS信息软件包用于操作和执行特征识别、识别、分类、计算和地面实况。还使用了一份结构化问卷来收集关于一些生计活动、生计活动对水供应的影响以及气候变化等方面的数据。二级数据集包括使用Bekkorea的卫星图像，这是从尼日利亚遥感中心和尼日利亚气象中心获得的，乔斯1987- 2017年。经过分析，发现森林植被正在迅速消失，建筑面积增加，森林和水体萎缩。环境温度和碳积累严重增加，而降雨量严重减少，导致气候变化和水资源供应减少。除其他外，还建议应采用植树造林这一可行、可持续、廉价和切实可行的替代生计来源，以减轻对自然生态系统的压力。
This study aims to assess how human livelihood activities influence climate change and water resource availability in the Northern part of Cross River State, Nigeria. Majorly, the paper looked at how human livelihoods activities like deforestation for agricultural expansion, carving, and timber, exploitation of non-timber forest products, sand mining, and faulty agricultural practices among others had influenced the removal of forest vegetation cover, how these activities also influenced the reduction in rainfall and subsequent paving of ways for climate change. These activities contributed greatly to increasing ambient temperature orchestrating carbon accumulation in the surrounding environment and reduction in the amount of rainfall within the study area. Using both soft and hardware computer applications including German 12 handheld GPS, and Integrated Land and Water Information System (ILWIS), were used for data collection. Both quantitative and qualitative data were collected for the study. The GIS information software package was used to manipulate and perform feature identification, recognition, classification, calculation, and ground-truthing. A structured questionnaire was also used to collect data on some livelihood activities, the influence of livelihoods activities on water availability, and climate change among others. Secondary data set include the use of satellite imageries of Bekwarra, this was acquired from the Nigeria Center for Remote Sensing and Nigerian Meteorological Center, Jos for 1987- 2017. After analysis, it was found that the forest vegetation cover is fast disappearing, the built-up area had increased and the forest and water bodies are shrunken. Ambient temperature and carbon accumulation had seriously increased, while rainfall has reduced seriously leading to climate change and reduced water availability. It was recommended among others that tree planting and afforestation, alternative sources of livelihood that are feasible, sustainable, cheap, and practicable should be introduced to reduce pressure on the natural ecosystem.
