Wetlands are significant for ecosystem services such as nutrient cycles, soil formation and water treatment. Nearly half of the world's wetlands have vanished in the last century because of anthropogenic activities, agricultural land use, and urban development, one of such places that are faced with the challenges of sustainability is the wetland habitats. This study aimed at assessing the spatiotemporal characteristics of wetlands ecosystem in the Niger Delta Region of Nigeria from 1986-2016. The secondary data include raw satellite imageries obtained from the archive of the United States Geological Survey and Earth Explorer. The data set includes a notable period of four years landsat images for, 1986, 1996, 2006 and 2016. The maps were projected using Universal Transverse Mercator (UTM) projection system and datum WGS 84 of zone 32. Satellite images of the study area were acquired from the United States Geological Survey (USGS). The USGS uses the LandSat5 Thematic Mapper (TM) Landsat7 Thematic Mapper, Enhanced Thematic Mapper (ETM+), Thermal Infrared Sensor (TIRS) and Landsa8 Operational Land Imager (OLI) to generate high resolution images that are useful for this type of study. The satellite imageries were also analyzed using GIS and Remote Sensing techniques by computing of Normalized Differential Vegetation Index (NDVI) values for the entire study area by conversion of spectral reflectance values into NDVI values. The satellite images covering the area were acquired and analyzed using ArcGIS10.6. A total area of 25,053.93 (km 2) was delineated in the study area. After processing the imagery, five land use/land cover (LULC) classes were developed in ArcGIS environment, such as Built-up area, Fallow land, Vegetation, Wetland and Waterbody. This study concludes that changes in wetland landscape patterns will produce profound impacts in urban areas where there are rapid anthropogenic activities.

The study aim is to detect and map the LULC changes in Ukwuani Local Government Area of Delta State over the period of 36years (1990-2014). In this study, three data set of Landsat Satellite images were layer stacked after which supervised classification in EARDAS imagine software was carried out and mapping in Arc GIS software. Four land use and land cover categories were classified into Built-up areas, Cultivation, Vegetation, and Waterbody. The result of the study shows a rapid growth in built-up land between 2002 and 2014 while the periods between 1990 and 2002 witnessed an increment in this class also. Findings of the study also show that there would be an accelerated increase in built-areas because of development that is coming to the study area in recent years. The study, therefore, recommends building towards the outskirts through the provision of incentives and forces of attraction that are available at the city centre in these areas. The study further recommends that the government should encourage afforestation in the study area to reduce the loss of biodiversity, inducing high rates of extinction and a worldwide depletion of biological diversity at genetic, species and ecosystem levels.

Flooding may occur as an overflow of water from water bodies, such as river, lake or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rain water on saturated ground in an area. To find out the most vulnerable communities, the Digital Elevation Model (DEM) and location data of selected communities were used. The Image Re-class and Map Overlay were performed on QGIS software to identify communities that are most affected. The result shows that the region has no river channel that discharge excess water easily. It also shows that four, out of twelve settlements were located at the high risk zone. The settlements are Uniport, Omuoda, Omuahunwo and Okparagwa. It was recommended that the high risk zone in the area should be provided with artificial water channel that will contain and convey surface sun-off to ...

They reduce flooding, replenish drinking water, filter waste, provide urban green spaces, and are a source of livelihoods in most urban areas. This study aims to geo-spatially analyze urban wetland loss in Obio/Akpor Local Government Area (LGA), Rivers State, Nigeria. The study analyses land use /land cover changes (LULC) using Landsat7 UTM images of 2000, 2009 and 2018. The satellite images covering the area were acquired and analyzed using ArcGIS10.6. A total area of 25,773.39 sq km was delineated in the study area. After processing the imagery, five LULC classes where developed in ArcGIS environment, such as wetland, built-up area, vegetation, water bodies and bare surface. The study shows that the urban land-use of Obio-Akpor LGA had changed dramatically during the period of 18 years. In 2000, wetlands occupied the second-lowest classes with 9.12% (2352.15 sq.km) of the total classes due to high level of urban developmen...

Empirical research has shown that the problems of social disparity (inequality) particularly in urban areas are on the increase and is gaining global and local attention. Despite the efforts of successive governments in the study area to combat this social problem, it is still raising its head in form of unequal access to educational facilities, health care, urban housing, good roads, and emergency services. This study, therefore, spatially assessed urban facilities and services in Port Harcourt metropolis, Nigeria. The mixed research method was adopted. However, the sampling size for the study comprises of 160 users of these urban facilities/services and staff of the facilities who were ...

Research paper thumbnail of Effects of Municipal Abattoir Waste on Water Quality of Woji River in Trans-Amadi Industrial Area of Port Harcourt, Nigeria: Implication for Sustainable Urban Environmental Management

It examines the effects of abattoir wastes on water quality of the Woji River in the Trans-Amadi industrial area of Port Harcourt, Nigeria. The research was premised on the fact that untreated wastes from the Trans-Amadi abattoir are discharged directly into open drainage which flows into the river. Water samples were collected from nine points along the stream (upstream; 3 samples, downstream; 3 samples, fallout; 3 samples) and subjected to physico-chemical laboratory analysis for total dissolved solids (TDS), temperature, pH, turbidity, hardness, iron content, nitrate, sulphate, magnesium, nickel, copper as well as some biological parameters. The results obtained from these parameters were at variance with the allowable limits of WHO standards for human use and aquatic life. The result further showed that the abattoir effluent has lowered the quality of the receiving Woji River particularly at fallout point and downstream. There is, therefore, need to stop the discharge of effluents into the receiving Woji River by upgrading the wastewater and urban waste management techniques of the abattoir to international standard. Contribution/Originality: This study contributes to the existing literature on the spatial analytical framework on abattoir wastes on water quality. This study uses a new estimation methodology of Peason's Coefficient to represent the relationship between microbiological and physico-chemical parameters of the river. 1. INTRODUCTION According to the UNICEF (2013) 1,800 children under the age of five die every day from diseases associated with contaminated water. Obire and Wenedo (2003) in a related survey maintained that 11% of the UNICEF figure are Nigerians, yet water is viewed by some as an ordinary liquid made available and abundant by nature while others say natural water is relatively dilute aqueous solutions. On the contrary, water is a vital natural resource necessary for existence and so its quality should be strictly monitored and maintained. It is an essential component for human existence as it constitutes 65% of man's composition, 57% of the matter of earth's crust and necessary for the survival of vegetable matter, plants and animal life. In urban areas, the careless disposal of municipal abattoir waste, industrial effluents and other wastes may contribute greatly to the poor quality of the water (Chindah et al., 2004; Nwankwoala et al., 2018). Pollution of freshwater bodies (rivers, lakes, pond and streams) by nutrients is mostly experienced as a result of industrial discharge, municipal abattoir discharge, domestic sewage disposals,

It identified that poverty reduction strategies in Nigeria has always been top-down and generalised. Policy makers and planners have never considered differentiating urban from rural poverty and therefore, the contributions of urban agriculture has not been really appreciated. This paper reviewed urban agriculture from three developmental phases in Nigeria and suggested that to understand what it is and what it does, it should be city specific when defining it. it suggested that this should be done in regards to the features of urban agriculture and in relation to the city's economy. This is because what prompt someone to engage with urban agriculture in London is different from the motivation of those in Port Harcourt City.The paper concluded that three social relations are important in understanding why people engage with urban agriculture in...

At present, not much has been done about the subject matter but great damage has been traceable to it both at workplaces and mobility at large. The importance of considering the impact of abandoned broken down vehicles on road users in urban areas cannot be over emphasised. According to FRSC (2015), the road transport system accounted for over 75% of mobility needs in Nigeria. The abandonment and near collapse of the rail system by successive Federal Governments and the high cost of air travels have put quite a lot of pressure on the nation's road transport industry. It is therefore imperative that plans should be formulated and executed on how free accessibility can be possible to reduce pressure on roads for vehicles, passengers and other road users. Nigeria became a republic in 1963. Under the republican constitution of Nigeria, certain principal enactments that are traffic related were introduced in the various regions and Lagos.

Flooding may occur as an overflow of water from water bodies, such as river, lake or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it may occur due to an accumulation of rain water on saturated ground in an area. To find out the most vulnerable communities, the Digital Elevation Model (DEM) and location data of selected communities were used. The Image Re-class and Map Overlay were performed on QGIS software to identify communities that are most affected. The result shows that the region has no river channel that discharge excess water easily. It also shows that four, out of twelve settlements were located at the high risk zone. The settlements are Uniport, Omuoda, Omuahunwo and Okparagwa. It was recommended that the high risk zone in the area should be provided with artificial water channel that will contain and convey surface sun-off to ...

They reduce flooding, replenish drinking water, filter waste, provide urban green spaces, and are a source of livelihoods in most urban areas. This study aims to geo-spatially analyze urban wetland loss in Obio/Akpor Local Government Area (LGA), Rivers State, Nigeria. The study analyses land use /land cover changes (LULC) using Landsat7 UTM images of 2000, 2009 and 2018. The satellite images covering the area were acquired and analyzed using ArcGIS10.6. A total area of 25,773.39 sq km was delineated in the study area. After processing the imagery, five LULC classes where developed in ArcGIS environment, such as wetland, built-up area, vegetation, water bodies and bare surface. The study shows that the urban land-use of Obio-Akpor LGA had changed dramatically during the period of 18 years. In 2000, wetlands occupied the second-lowest classes with 9.12% (2352.15 sq.km) of the total classes due to high level of urban developmen...

Empirical research has shown that the problems of social disparity (inequality) particularly in urban areas are on the increase and is gaining global and local attention. Despite the efforts of successive governments in the study area to combat this social problem, it is still raising its head in form of unequal access to educational facilities, health care, urban housing, good roads, and emergency services. This study, therefore, spatially assessed urban facilities and services in Port Harcourt metropolis, Nigeria. The mixed research method was adopted. However, the sampling size for the study comprises of 160 users of these urban facilities/services and staff of the facilities who were ...

Research paper thumbnail of Effects of Municipal Abattoir Waste on Water Quality of Woji River in Trans-Amadi Industrial Area of Port Harcourt, Nigeria: Implication for Sustainable Urban Environmental Management

It examines the effects of abattoir wastes on water quality of the Woji River in the Trans-Amadi industrial area of Port Harcourt, Nigeria. The research was premised on the fact that untreated wastes from the Trans-Amadi abattoir are discharged directly into open drainage which flows into the river. Water samples were collected from nine points along the stream (upstream; 3 samples, downstream; 3 samples, fallout; 3 samples) and subjected to physico-chemical laboratory analysis for total dissolved solids (TDS), temperature, pH, turbidity, hardness, iron content, nitrate, sulphate, magnesium, nickel, copper as well as some biological parameters. The results obtained from these parameters were at variance with the allowable limits of WHO standards for human use and aquatic life. The result further showed that the abattoir effluent has lowered the quality of the receiving Woji River particularly at fallout point and downstream. There is, therefore, need to stop the discharge of effluents into the receiving Woji River by upgrading the wastewater and urban waste management techniques of the abattoir to international standard. Contribution/Originality: This study contributes to the existing literature on the spatial analytical framework on abattoir wastes on water quality. This study uses a new estimation methodology of Peason's Coefficient to represent the relationship between microbiological and physico-chemical parameters of the river. 1. INTRODUCTION According to the UNICEF (2013) 1,800 children under the age of five die every day from diseases associated with contaminated water. Obire and Wenedo (2003) in a related survey maintained that 11% of the UNICEF figure are Nigerians, yet water is viewed by some as an ordinary liquid made available and abundant by nature while others say natural water is relatively dilute aqueous solutions. On the contrary, water is a vital natural resource necessary for existence and so its quality should be strictly monitored and maintained. It is an essential component for human existence as it constitutes 65% of man's composition, 57% of the matter of earth's crust and necessary for the survival of vegetable matter, plants and animal life. In urban areas, the careless disposal of municipal abattoir waste, industrial effluents and other wastes may contribute greatly to the poor quality of the water (Chindah et al., 2004; Nwankwoala et al., 2018). Pollution of freshwater bodies (rivers, lakes, pond and streams) by nutrients is mostly experienced as a result of industrial discharge, municipal abattoir discharge, domestic sewage disposals,

It identified that poverty reduction strategies in Nigeria has always been top-down and generalised. Policy makers and planners have never considered differentiating urban from rural poverty and therefore, the contributions of urban agriculture has not been really appreciated. This paper reviewed urban agriculture from three developmental phases in Nigeria and suggested that to understand what it is and what it does, it should be city specific when defining it. it suggested that this should be done in regards to the features of urban agriculture and in relation to the city's economy. This is because what prompt someone to engage with urban agriculture in London is different from the motivation of those in Port Harcourt City.The paper concluded that three social relations are important in understanding why people engage with urban agriculture in...

At present, not much has been done about the subject matter but great damage has been traceable to it both at workplaces and mobility at large. The importance of considering the impact of abandoned broken down vehicles on road users in urban areas cannot be over emphasised. According to FRSC (2015), the road transport system accounted for over 75% of mobility needs in Nigeria. The abandonment and near collapse of the rail system by successive Federal Governments and the high cost of air travels have put quite a lot of pressure on the nation's road transport industry. It is therefore imperative that plans should be formulated and executed on how free accessibility can be possible to reduce pressure on roads for vehicles, passengers and other road users. Nigeria became a republic in 1963. Under the republican constitution of Nigeria, certain principal enactments that are traffic related were introduced in the various regions and Lagos.
