Bioremediation is an option that offers the possibility to destroy or render harmless various
               contaminants using natural biological activity. As such, it uses relatively low-cost, low-
               technology techniques, which generally have a high public acceptance and can often be carried
               out on site. It may not always be suitable, however, as the range of contaminants on which it is
               effective is limited, the time scales involved are relatively long, and the residual contaminant
               levels may not always be achievable.

               I would like to refer you again to the University of Port Harcourt Stanley Lawson Chair of
               Environmental Geology organized workshop on remediation of hydrocarbon polluted sites in
               September 2012. In his welcome address, the convener, Prof. EnuvieAkpokodje, highlighted the
               essence of the workshop when he noted that there are:

                 Numerous hydrocarbon contaminated sites (soil &water resources) in Nigeria that need effective
                 Significant number of remediation efforts have failed to achieve the desired results, especially in
                   highly polluted sites;
                 No harmonized &transparent procedures/policies for documentation &remediation of
                   hydrocarbon contaminated sites;
                 No regular forum for open discussion and sharing of experiences &knowledge on technical,
                   management, policy and regulatory issues between government, industry, technical experts,
                   communities &NGOs; and
                 Inadequate involvement of host communities in development and implementation of
                   remediation programmes. (Akpokodje, 2012).

               It therefore follows from the points above that the stakeholders in the oil and gas exploration
               areas (including you) must build capacity to encourage the effective delivery of bioremediation
               technologies as a panacea to the worsening status of the hydrocarbon pollution resulting from
               oil and gas exploration in the Niger Delta. As we gather here this week to discuss this issue, it
               is my hope that you will be better informed to take (or advice on) informed decisions on
               pollution and environmental management challenges towards a greater and greener Niger Delta
               region of Nigeria.

               The emerging dynamics associated with oil spill incidents in the Niger Delta of Nigeria have no
               doubt continued to generate political and scientific interests, yet with no lasting solution in
               sight. For this, scientists have proposed the   need for an “Oil Spill Information Management
               System (OSIMS)” for the country. Central to the effective functioning of this system that has
               been successfully implemented in other parts of the world according to Udoh (2006), is the use
               of Geographic Information System (GIS) and Remote Sensing technologies. The application of
               these geo-information technologies has become imperative to the search for solution to the
               pollution and environmental management profile in the Niger delta. This is because researches
               have shown that, as long as petroleum resources are explored and exploited, spills will still
               occur coupled with its negative consequences and effects on the people and the environment
               that host these activities.

               From the foregoing and the fact that Nigeria's oil and gas deposits are mainly found in the Niger
               Delta region that by nature is very difficult to clean up if contaminated, there is the need to
