Gas Flaring And Soil Quality Dynamics In Lowland Rainforest Environment Of Delta State, Nigeria

Abstract

This study examined gas flaring and soil quality dynamics within the lowland rainforest environment of Delta State in south-southern Nigeria. This study adopted both experimental and quasi experimental design approaches; while the study area was divided into 5 (Ebedei, Okpai/Kwale, Erhoike/Kokori, Otu-Jeremi, Ekpan/Ubeji) using stratified random sampling technique. From each gas flaring site, 4 sampling spots were established at 0 - 0.1km, 0.5km, 1km, and rainforest control site to make a total of 20 sampling spots, from which soil samples were collected from the topsoil (0-15 cm) and subsoil (15-30 cm). Standard approaches were adopted in the field samples collection. Soil samples collected were put into labelled polythene bags and taken to laboratory for analysis on some physical and chemical properties. All data generated were statistically analysed using descriptive and inferential statistics. Results of statistical tests showed that: there was no significant difference in soil properties between the topsoil and subsoil at the distances away from gas flaring sites and adjacent rainforest; there was no significant variation in topsoil properties amongst the different established distances away from gas flaring sites and the adjacent rainforest; there is no significant variation in subsoil properties amongst the different established distances from gas flaring sites and the adjacent rainforest; distance decay does not significantly influence soil properties to vary within gas flaring sites and adjacent rainforest. The impact of gas flaring does not significantly differ with distance away from flaring site within the rainforest environment. Therefore, control of temperature effects on crop productivities and plants adaptation within gas flaring area is recommended.
