Assessment of the Impact of Illegal Petroleum refining on Sustainable Agriculture in the Niger Delta, Nigeria

Abstract

This study investigates the multifaceted impacts of illegal petroleum refining, commonly known as "kpo-fire," on sustainable agriculture and rural livelihoods in the Niger Delta region of Nigeria. The primary objective was to quantify the extent of environmental contamination, assess its direct effects on crop growth and yield, and elucidate the consequent socio-economic implications for farming communities. Employing a mixed-methods approach, the methodology integrated physico-chemical analysis of soil and water samples, agricultural yield assessments, and comprehensive socio-economic surveys with qualitative insights from interviews and focus group discussions. Findings revealed severe contamination of agricultural lands and water bodies with elevated levels of petroleum hydrocarbons and heavy metals, consistently exceeding environmental standards. This contamination significantly reduced crop growth parameters and yields, leading to substantial income losses (e.g., 60% reduction in farm income) and widespread food insecurity among affected households. Furthermore, evidence of contaminant bioaccumulation in edible crops posed significant public health risks. One key recommendation from this study is the urgent need for robust alternative livelihood programs for individuals involved in illegal refining, coupled with stringent enforcement measures, to foster sustainable agricultural practices and improve community well-being in the region.
