Abstract

The potential impacts of gully erosion over South Eastern Nigeria are a worrisome scenario. It has resulted in the displacement of millions of habitats, agricultural, and economic losses. The result of the effect of Nigerian Erosion Watershed Management Project (NEWMAP) monitoring and evaluation on the effect of gully erosion on economic development in this study has revealed a positive significant influence at P < 0.05 over the study region. Also, it is revealed that NEWMAP programmes have significantly covered some constructions of hydraulic structures for flood routing and soil erosion control in South East, Nigeria. This intervention has significantly reduced the rate of land degradation occasioned by soil erosion, protection of watershed and agricultural land, which has thus been responsible for improved agricultural production. In conclusion, it is imperative to conduct periodic monitoring and evaluation of the activities of NEWMAP to building a strong evidence-based mechanism that enhances assessment of the diverse range of intervention projects on the dwellers of South-East extraction.

NEWMAP对尼日利亚东南部沟蚀控制和环境发展的影响评价

尼日利亚东南部沟壑侵蚀的潜在影响令人担忧。它造成了数百万个栖息地的流离失所，农业和经济损失。本研究尼日利亚侵蚀流域管理项目(NEWMAP)监测评价沟沟侵蚀对经济发展的影响结果显示，研究区域沟沟侵蚀对经济发展的影响呈显著正相关，P < 0.05。此外，报告还显示，尼日利亚东南部的新地图方案在很大程度上涵盖了用于防洪和控制土壤侵蚀的一些水利结构的建设。这一干预措施大大降低了土壤侵蚀、保护分水岭和农业用地所造成的土地退化率，从而提高了农业生产。总之，必须对新计划的活动进行定期监测和评估，以建立一个强有力的循证机制，加强对东南采区居民各种干预项目的评估。
