Abstract: Rural to urban migration has been a disturbing factor in Nigeria. The urban cities have become over populated resulting into poor provision of comfortable and healthy accommodation for the citizenry. The menace has further metamorphosed into complex units of socio-economic and cultural degradation, increasing youth unemployment, poor housing delivery, and depletion of the ozone layers due to carbon dioxide emission from small electric generators called “I pass my neighbor”. The situation is no longer convenient to be curtailed because of the limitations of the existing institution to provide mechanism to curtail the growing challenges. This indicates a factor of undermining urban poor of affordable and decent housing, which makes them “homeless. The research aims at conveying into luminance the drivers of low energy materials that could be employed through sustainable measures to deliver public housing in Nigeria. The objective brings forth considerations for application of low energy materials that can be integrated at the design stage to reduce the energy used in achieving comfort and limit the overall energy consumption of residential buildings in Nigeria. The purpose is to make public housing affordable and sustainable in Nigeria. The study employed the use of qualitative data analysis from relevant literatures. The results obtained indicate the high energy delivery in Nigeria’s public housing reflects the overgrowing poverty level in the country. The population living in poverty has remarkably grown from 1980-2010. This factor has made it difficult for the majority poor populace to own a house due to the high cost involved in obtaining a high energy material for building construction. The study recommends a drift to low energy materials, which involves lesser energy of production and are locally found in the country, and tends to provide affordable housing to the poor living in urban centers. Hempcrete, cob, raw earth, sheep wool, bamboo, rice hull, wattle and daub, rammed earth, the mud, adobe, fire brick, are available traditional building materials with low energy richly found in Nigeria, government and private developers should adopt them in construction of dwellings to curtail the limited provided accommodation for the increasing population in urban centers and to provide decent, affordable, and sustainable accommodation to Nigerians.

Abstract: The setbacks of deforestation over the years have given light to awareness on the importance of regeneration. The benefits of forest regeneration are numerous both to the environment and man. The main objectives of this study were to assess forest regeneration dynamics and its implication on landscape projection in Oku. This study adopted both primary and secondary methods of data acquisition. This involved the administration of questionnaires, field visits, focus group discussions, observation and key informant interviews. This was practicable based on the accessibility and the potentials of the study area. In addition, satellite images of the study area were exploited to portray the rate of deforestation over the years and extent of tree planting within the area. Collected data was expected to enhance an understanding of endeavours of the local population to protect and regenerate exploited areas. The study found out that the local population are conscious, appreciative and encourage forest regeneration activities. Questionnaire exploitation revealed that 91% of the population plant trees in their farms. These trees range from soil fertilizer species, fruit trees and suitable trees for wood carving. The study equally revealed that 80% of local NGOs present within the matrix area are involved in forest regeneration. As a result of this, the cumulating local efforts of forest revival respects mitigation designed on climate change. The fact that local communities accept the canons of forest regeneration is of maximum importance in guaranteeing environmental benefits.

Abstract: The world’s coastlines provide essential development benefits to most communities for livelihood sustenance. The proximity of communities to coastlines elects the need to exploit the water resources through fishing and transportation. Given that coastlines are subjected to changes, this study intends to investigate coastal dynamics and implication for development of the fishing communities along the shoreline region of Toube. A descriptive research design was adopted with a sample size of 300 respondents which employed a random sampling technique. Data was collected from both primary and secondary sources and was analyzed qualitatively and quantitatively by the use of arithmetic mean and ArcGIS 10.2. The coastal dynamics between 1984 and 2017 were observed using shoreline GPS Way Point that was matched by Landsat images of 1984, 2000 and 2017. Findings showed that prolonged backwash process caused by sea level rise provoked coastal erosion and submergence of shoreline communities. The results revealed that between 1984 and 2017, the shoreline of Toube has been retreating at a rate of 9.56 m per year. The retreat rate equally varies along Toube coastlines revealing that Cap shoreline has retreated some 452.4 m between 1984 and 2017 while Itiekot-Chekiri and Small Toube retreated by 254.87 m and 239.61 m respectively between 1984 and 2017. These coastal fishing communities are vulnerable to coastal erosion, settlement submergence, destruction of fishing barns, displacement of people and disruption of coastal activities with huge socio-economic losses. The study opts for the stabilization of the shorelines through the use of sand bags, sea walls and the creation of buffer zone with mangrove trees in order to reduce the exposure of the fishing communities to the intensity of the coastal dynamics in Toube.
