“…There is no way that you can drill for oil without destroying plants and animals. The negative impact of the extractive industries and other anthropogenic factors on biodiversity in the region is acknowledged by many scholars Zabby (2004), Ugochukwu & Ertel (2008), Kadafa (2012), Mmon & Arukoyo (2009), and Agbagwa (2014). In terms of animals, a wide varieties use to be common in the Niger Delta.…”

Biodiversity refers to the varieties, multiplicity, and diversity of life in the ecosystem. It is being lost on a daily basis in Nigeria’s Niger Delta. This is as a result of the environmental degradation caused by oil exploration and gas activities. In the process of drilling for oil and exploring for gas resources, the natural environment such as plants, animals and their communities is destroyed and endangered. Oil exploration activities continue unabated in the Niger Delta. There is need to combat biodiversity loss if not many of the benefits from biodiversity will be lost. With critical analysis the philosophy of deep ecology is examined and presented as having potentials to contribute to conserving biodiversity in Nigeria’s Niger Delta. The paper concludes that there is vital need to preserve biodiversity using deep ecology values. Keywords: Deep ecology, biodiversity, conservation, Niger Delta, Nigeria, and Philosophy

We examine Nigerian preferences for the mitigation of negative impacts associated with oil and gas production using a discrete choice experiment. We analyse the data using a Bayesian 'infinite mixtures' model, which given its flexibility can approximate an array of existing model specifications including the mixed logit and finite mixture specifications. The application of this model to our data suggest multimodality in the marginal willingness to pay distributions associated with mitigation policy characteristics. Individuals are willing to pay for mitigation of negative impacts, but are not necessarily willing to trade-off very large increases in unemployment or poverty to achieve these benefits.

“…The study area, Kporghor, is located in the Niger Delta region of Nigeria which is one of the largest wetlands in the world that has substantially degraded due to oil pollution necessitating in 2011, the assessment of area by a special team of the United Nations Environment Program [72,73]. It receives some of the highest rainfall in the world of up to 3000 mm annually [74].…”

Normalized Difference Vegetation Vigour Index: A New Remote Sensing Approach to Biodiversity Monitoring in Oil Polluted Regions

2018

Biodiversity loss remains a global challenge despite international commitment to the United Nations Convention on Biodiversity. Biodiversity monitoring methods are often limited in their geographical coverage or thematic content. Furthermore, remote sensing-based integrated monitoring methods mostly attempt to determine species diversity from habitat heterogeneity somewhat reflected in the spectral diversity of the image used. Up to date, there has been no standardized method for monitoring biodiversity against the backdrop of ecosystem or environmental pressures. This study presents a new method for monitoring the impact of oil pollution an environmental pressure on biodiversity at regional scale and presents a case study in the Niger delta region of Nigeria. It integrates satellite remote sensing and field data to develop a set of spectral metrics for biodiversity monitoring. Using vascular plants of various lifeforms observed on polluted and unpolluted (control) locations, as surrogates for biodiversity, the normalized difference vegetation vigour index (NDVVI) variants were estimated from Hyperion wavelengths sensitive to petroleum hydrocarbons and evaluated for potential use in biodiversity monitoring schemes. The NDVVI ranges from 0 to 1 and stems from the presupposition that increasing chlorophyll absorption in the green vegetation can be used as a predictor to model vascular plant species diversity. The performances of NDVVI variants were compared to traditional narrowband vegetation indices (NBVIs). The results show strong links between vascular plant species diversity and primary productivity of vegetation quantified by the chlorophyll content, vegetation vigour and abundance. An NDVVI-based model gave much more accurate predictions of species diversity than traditional NBVIs (R-squared and prediction square error (PSE) respectively for Shannon's diversity = 0.54 and 0.69 for NDVVIs and 0.14 and 0.9 for NBVIs). We conclude that NDVVI is a superior remote sensing index for monitoring biodiversity indicators in oil-polluted areas than traditional NBVIs.
