Abstract: This study adopted Remote Sensing and GIS in assessing Land Use and Land Cover (LULC)/Land Surface Temperature (LST) variation in Abuja Municipal, FCT from 1986 to 2016. The thirty-year study period was chosen with the specific objective to determine the relationship between LULC and LST using a correlation analysis. Three Landsat TM/ETM+ images of the study area (1986, 2001 and 2016) were used to carry out the study. LULC was found to increase by 246.96 km2 (86.4%) in areal extent of built-up between 1986 and 2016; the spatial extent of the LST was found to increase on average from 23.5°C to 30.2°C. The correlation analysis showed a strong coefficient of determination (r2). The correlation analyses proved that the LULC classes were strongly related to LST. A strong correlation between the LULC classes and LST was observed at 0.8266, 0.9486, and 0.77 for 1986, 2001, and 2016. The coefficient of determination (r2) for 2016 was 0.77, being a strong indicator that a strong relationship existed implying that built-up areas were major drivers of the variation in the LST in Abuja Municipal. To promote thermal comfort in Abuja Municipal, urban planning, and control of building patterns tree-planting exercises are some of the recommendations made.

Abstract: A total of 30 samples were collected from six different locations from of Abuja Federal Capital Territory (FCT), the administrative capital of Nigeria which is situated in the central part of the country. The samples which were thor-oughly prepared following known dosimetry procedures were analyzed for 40K, 238U and 232Th by the method of Gamma ray spectrometry using NaI(TL) detector coupled to a multichannel analyzer. The activity concentrations in the top soils in these locations for 40K, 238U and 232Th range from 301 ± 26.52 to 928.84 ± 80.57, Not detectable (ND) value to 27.68 ± 8.21 and 4.65 ± 1.46 to 22.48 ± 5.26 respectively. The average absorbed dose rate and the annual effective dose equivalent were found to be 40.33 nGyh–1 and 49.46 µSv respectively. The value of annual effective dose equivalent is low compared to the world average of 70 µSv specified by UNSCEAR for an outdoor effective dose, hence the chances of radiological hazards to the health of the populace are generally low.

Abstract:
From the declaration made by the African Mayors in Senegal; the Mayors and Municipal Health Officers of the Americas in Columbia; the City Executives of Cities and Local Governments of the World in Spain and in the context of the Millennium Development Goals MDG 1&7; there is a need for increased food production in urban and peri-urban areas UPA in the world. Sub-Saharan Africa faces more development challenges than any other major region of the world with most of the people living in slums, without access to adequate food, water, or sanitation. UPA contributes to increased food security, nutrition and livelihoods in a combination of ways giving access to consumer markets; less need for packaging, storage and transportation of food; potential agricultural-related jobs and incomes; non-market access to food for poor consumers; availability of fresh, perishable food. In Abuja FCT, 40% of the populations in UPA are farmers, a reason why the agricultural quality of its groundwater which is used for irrigation begs for our attention. 33% of the fresh vegetables in the Abuja Federal Capital Territory (FCT) are produced in Abuja UPA. In order to assess groundwater for agro-industrial suitability the following were used: Physicochemical parameters (pH, Temperature, Electrical Conductivity), Sodium Adsorption Ratio SAR, Permeability Index PI, Magnesium Adsorption Ratio MAR, Percent Sodium %Na, Kelly’s Ratio KR and Residual Sodium Carbonate RSC and the Wilcox diagram. pH ranged from, 4.8 - 7.9; EC, 13.4 - 1634 μS/cm; Temperature, 26℃ - 36.1℃ and TDS, 17.42 - 1094.78 mg/L.SAR (0.1 > SAR < 2.1), Percent Sodium (7.11 > %Na < 100), KR (0 > KR < 0.68), RSC (-9.8 > RSC < 0.55), PI (13.9 > PI < 932.4), and MAR (0 > MAR < 80.1). Comparing these values to WHO and the Nigerian Water Quality guidelines, SAR, %Na, KR, RSC, values are 100% suitable, while PI, 96.81% suitable, and MAR 56.46% unsuitable respectively for irrigational purposes in agriculture. The quality classifications of irrigation water based on the values: Sodium Adsorption Ratio SAR, Wilcox, Kelley Ratio KR, Residual Sodium Carbonate RSC, Permeability Index PI and Percent Sodium %Na; indicate that groundwater of Abuja FCT is suitable for irrigation purpose on all soil types and that the groundwater will not degrade the soil. However, United States Soil Salinity USSL Index of Abuja FCT groundwater fall in “very low to high salinity” and “low sodium hazard zone” and Magnesium Adsorption Ratio MAR indicates half of the groundwater as “not suitable”. Hence the groundwater in Abuja FCT should be used only on soils that are well drained.

Abstract: A geoelectrical investigation involving fifty Schlumbeger vertical electrical soundings were carried out along traverses established in the west-east azimuth at the Dape phase III Housing Estate, FCT Abuja to evaluate the aquifer protective and corosivity of the near surface materials. Corrosivity, isopach and total longitudinal unit conductance (S) maps were generated from the combination of first and second order geoelectric parameters. The eastern, southeastern parts and parts of southwestern end of the estate are characterized by slightly corrosive to moderately corrosive materials (50ohm-m< p< 150ohm-m) and moderate overburden thickness (>20 m). Using the total longitudinal unit conductance S, the estate is classified into zones of weak (0.1-0.19) and poor (< 0.1) protective capacity. The results reasonably provide a basis for which groundwater potential zones are appraised for safety in case industrial facilities are planned for the area under study. The study also presents new environmental factors that may perhaps be considered at planning stages of residential and industrial estates.

Ethiopian Journal of Environmental Studies and Management , 2012,
Abstract: This paper is aimed at investigating the uptake of heavy metals by plan, since these plants are being consumed directly by people. The study was conducted within a dumpsite located at Mpape in the Abuja Municipal Area Council, Federal Capital Territory Abuja. Metals are essential for maintaining human health throughout life. Intake of heavy metal contaminated vegetables may pose a risk to the human health. Plants take in minerals from soil media or air through their roots or foliage. Understanding the distribution of some trace metals in some common vegetables and tuber crops is important for establishing baseline concentrations from which anthropogenic effects can be measured. The trace metal distribution in some selected vegetables and tuber crop cultivated around Mpape Dumpsite were determine. All the parameters investigated were found present in the three plants species analysed. The concentrations of heavy metals in all the samples cultivated around the dumpsite were higher than those from the control site and they are also above the FEPA limit except Ion and Zinc in spinach that was within the limit. It is important to educate the farmers on the best farming practice and regular monitoring of heavy metal contamination should be encouraged in order to avoid possible consumption of contaminated vegetables.

Abstract: The effects of the dynamics of climate on agricultural production are the thrust of this paper. Temperature, rainfall and crops (rice, maize, cassava, groundnut and garden eggs) data were collected for a period of 10 years from the meteorological and agricultural department of the Agricultural development programme (ADP) Gwagwalada. The work assembled and analysed all available data which are needed for evaluating the implication of climate change on agricultural production in the FCT. Some measure of central tendencies were used to critically analyse the parametres such as arithmetic mean, standard deviation, coefficient of variance, simple regression, correlation and multiple regression model to correlate the relationship among rainfall, temperature and crop yield. The paper concludes there exists positive relationship between each climatic element and crop yield but on a very weak significance; there has been constant increase in temperature over the years with 2009 having the highest of 35oC; there is decline in rainfall over the years, and subsequent decline in the productivity of the crops from the correlation carried out in the study. These recommendations were forwarded: Crop yield should be regressed on other environmental factors such as soil fertility etc.; A longer period of data could be collected for better analysis; and data on rainfall, temperature and other crops could be collected and investigated upon to correlate the result with this finding.

Abstract: The study was conducted to determine factors influencing the adoption of agro-chemicals technology by small-scale farmers in Kwali area council, of the Federal Capital Territory Abuja, Nigeria. Structured interview schedule was used to collect data for the study. Ten respondents were randomly selected from each of the eight districts making the area council giving a total of eighty respondents. Statistical tools involving means, frequency and percentage were used to analyze the data. Ordinary least square linear regression was used to determine factors influencing the adoption of agro-chemicals technology in the study area. The results of the study revealed that gender, age, farm income, marital status and years of farming experience have positive influence on the adoption of agro-chemicals in the study area. Management of Abuja Agricultural Development Project should endeavour to encourage farmers to form strong coherent group such as cooperatives to control agro-chemicals prices supplied by input representatives.

Abstract: It is reckoned worldwide that verocytotoxigenic Escherichia coli (VTEC) serotypes are important food borne pathogens causing severe health problems in humans. A cross sectional epidemiological study was carried out to determine the prevalence of VTEC serotypes (O157 and non O157) in both apparently healthy and diarrhoeic cattle in Abuja, FCT. A total of 718 faecal samples collected from abattoirs and cattle herds from Abuja, FCT representing 381 from apparently healthy and 337 from diarrhoeic cattle were analyzed. Primary isolation of typical E. coli was done using Eosin Methylene Blue (EMB) agar and performing biochemical tests. Samples were further analyzed using Cefixime, Tellurite-Sorbitol McConkey (CT-SMAC) agar to identify sorbitol and non sorbitol fermenting E. coli. Further characterization of both the sorbitol fermenting and non sorbitol fermenting E. coli was done using commercially procured latex agglutination test kits from Oxoid, United Kingdom. The prevalence of VTEC O157 in apparently healthy cattle was 1.84% and 2.96% for diarrhoeic cattle while the prevalence of non O157 VTEC was 3.67% and 7.12% for apparently healthy and diarrhoeic cattle respectively. There was no strong association (p > 0.05) between faecal consistency and infection with VTEC O157. A strong association (p < 0.05) however existed between faecal consistency and infection with non-O157 VTEC. Diarrhoeic cattle appear likely to be more affected. The implication of the study is that individuals in contact with cattle such as veterinarians, abattoir workers and cattle herdsmen are at risk of exposure to VTEC and proper hygienic control measures should be adopted.

Abstract:
The quality of groundwater is three fold: physical, chemical and biological. For water to be fit for human consumption, it must have satisfied all three quality aspects. Therefore, the groundwater biological quality of Abuja FCT can never be over emphasized since the wellbeing of the citizens of the capital territory, seat of the government of Nigeria, is of strategic importance. There are myths and realities about the biological quality of groundwater in fractured rock aquifers which must be clarified. Groundwater plays a very important role in the development of Abuja, Nigeria’s Capital as many private, government, and households establishments depend solely on hand-dug wells and boreholes for their daily water needs. This study evaluates the biological quality using total bacterial density (TBD), total coliform (TC), coliform bacteria (CB), faecal coliform (FC), total bacteria count (TBC), and salmonella species (SS) as biological pollution indicators. From physicochemical parameters: pH ranged from, 4.8 - 7.9; EC, 13.4 - 1634 μS/cm; Temperature, 26?C - 36.1?C and TDS, 17.42 - 1094.78 mg/L. Groundwater of Abuja FCT is not suitable for drinking as the species had the following concentration and percentages above the permissible limits for drinking water: TC (0 - 1280) 51.06%, FC (0 - 170) 19.15%, TBD (0 - 86.6) 98.94%, TBC (0 - 5120) 95.74%, CB (0 - 438) 74.47% and SS (0 - 223) 69.15%. Groundwater from Abuja FCT Granite-Gneiss fractured rock aquiferous formation is unfit for human consumption and an added danger to humans since it is usually assumed to be safe. Groundwater from Granite-Gneiss fractured rock aquifers could be the source of endemic outbreaks of waterborne diseases such as E. coli, Cholera, Gastroenteritis, Typhoid and Diarrhea; as such all groundwater from the aquiferous formations in Abuja FCT should be treated before consumption and use. Source protection strategies as well as monitoring are recommended although it may not serve the purpose for which it is intended since the potential for pollution is point and non-point sourced.
Empowerment of Indigenous Women in the Federal Capital Territory Abuja, Nigeria
MA Filaba
Ethiopian Journal of Education and Sciences , 2007,
Abstract: Nigeria's development of the new Federal Capital Territory in the central part of the country named Abuja 8,000 km2 in size greatly impacted on all spheres of lives of the host communities. However, the host communities of 845 settlements with over 316,000 people were exposed to urban violence and there was fear that they would be completely wiped out. The findings here are part of some surveys conducted between 1994 and 2000 on the impact of the FCT on the indigenous inhabitants. The research instruments were Focused Group Discussions and In Depth Interview Guides, Questionnaires, Observations and Content Analysis. The findings reveal that the first decade of the FCT Abuja posed challenges and the indigenous inhabitants found it difficult to adjust. With the FCDA and MFCT policies, women became empowered. The teeming urban population offered investment opportunities too, which women utilized that the former poor housewives gradually transformed into petty-business women, employees and so on, and was reflected in their improved living conditions.
