Inland water transport in Nigeria has had a long history of neglect by both government and the private sector. Little efforts were made to develop inland water transport facilities prior to the 1980s. This stems largely from policy inconsistency, limited private sector involvement, and conflicts between and among agencies involved in the management of inland water transport in Nigeria. Since the 1990s, however, the Federal Government of Nigeria has, taken a number of initiatives, including capital and infrastructure improvement, channels dredging and maintenance and installation of safety facilities to turn round the sector. This paper reports on the current spatial structure of inland water transport in Nigeria; its socio-cultural constraints and contributions to nation's economy, current navigable waterways and goods transported. The purposes are to create awareness, improve attitudes and isolates strategies which can assist all the operators in the inland water transport sector to improve service delivery. Data were collected through oral interviews, field observations and from relevant records in government agencies. Staff of inland water transport agencies, water transport operators and government official responsible for developing and managing inland water transport in Nigeria were interviewed. Additional secondary data were obtained from relevant government agencies. Findings revealed that inland water transport is more popular in the southern deltaic areas of Nigeria where extensive networks of navigable waterways exist. This mode of transport was found to impact positively on the nations' economy as it reduces haulage cost, expands business opportunities, creates jobs and boasts the revenue earned by all the stakeholders in the inland water transport sector. The major socio-cultural challenges which currently impede inland water transport in the study area were identified and described. The way forward is for the federal government to review its investment strategies in the sector and for water transport operators to priorities safety, quality, speed and flexibility in its operation.

Studies on global warming and climate change in Nigeria have grown by leaps and bounds in the last two decades. This paper reviews fifty three studies done on climate change hazard in Nigeria with a view to characterizing the studies and establishing the existing gaps in literature. The secondary objective of the paper is to establish the broad consensus of the Nigerian scientific community on critical issues relating to the climate change hazard. The paper started with the identification of the broad objectives of the studies done on the climate change hazard in Nigeria. This is followed by the classification of the studies and the discussion of the main significant contributions as well as an appraisal of the methods of investigations in the field where appropriate. The basic consensus reached were also identified and described. Finally, new directions for future research in the field are suggested.
