Global anthropogenic activities resulting in the emission of harmful greenhouse gases (GHGs) to the atmosphere have increased the challenges faced from climate change. The greater awareness of the need to mitigate climate variability has brought about intense focus on the adverse impacts of fossil-fuel based energy on the environment. Being the single largest source of carbon emissions, energy supply has attracted much attention and more so that, climate change impacts extend beyond national boundaries. Since energy use is sine qua non to economic development, scientists have reiterated the necessity of developing and utilising renewable energy. Although, past and present CO 2 emissions have and are majorly caused by industrialized countries, it is envisaged that future GHGs emissions would be mostly from developing countries as they industrialize. Renewable energy sources that include biomass, hydroelectric, wind, solar and hydrothermal systems, are carbon-neutral, releasing relatively no emissions. This paper discusses the initiatives associated with the provision of renewable energy to the energy mix in Nigeria as an indication of the country’s commitment to adopt a sustainable development strategy in shaping the economy. It reviews the literature and employs a discourse analysis to examine the limited use of renewable energy sources in Nigeria and the factors prevailing against their development. The paper concludes by identifying social and political obstacles as most significant roadblocks towards rapid implementation of a green economy through the deployment of renewable energy for sustainable development.

Wetlands play a very important role in the sustenance of both the surface and groundwater resources of the country. It is sad to observe that the country is fast losing her wetlands, as the rich wetlands are being seriously threatened by a number of anthropogenic and biophysical factors. Some of the notable human actions include population pressure, rapid urbanization, mining, oil and industrial waste pollution, overgrazing, logging, dam construction, transportation routes and other physical infrastructure. Others factors are uncontrolled tilling for crop production and unprecedented/unregulated land reclamation. Subsidence, saltwater intrusion, sand storm, desertification and droughts, invasion by alien floral and faunal species as well as marine and coastal erosion are natural threats to wetlands in Nigeria. Wetlands destruction affects negatively water supply and water resources management. This study examines in great detail the fate of wetlands in the face of climate change and recommends that efforts should be made to accurately document the country's wetland. The paper therefore suggested sustainable options for wetlands and water resources management in Nigeria. This, the paper opined, can be done through the strengthening of wetlands preservation and conservation regulation, mitigating the effects of climate change as well as the development of deliberate restoration programmes and policies aimed at sustaining degraded wetlands in Nigeria.
