    ANALYSIS OF RAINFALL AND TEMPERATURE PATTERNS ON CROP PRODUCTION IN NASARAWA STATE, NIGERIA
    (Department of Environmental Management, Nasarawa State University Keffi, 2021-08-08) Anzaku, I.M.; Alkali, Mohammed; Buba, Samaila; Usman, Salihu Lay
    This study assessed rainfall and temperature pattern in Nasarawa State. The objective of the study was to determine the rainfall and temperature pattern suitable for agriculmral production in Nasarawa State and also assess the rainfall and temperature trend in the study area. Data were collected for a period of 15years from the National Meteorological Agency (NIMET). The data were analyzed using the Pearson correlations and linear regression analysis. The results of the study showed an increase in maximum and minimum temperature at 0.168°C and 0.413°C respectively, coupled with unreliable rainfall of0.079 over the investigated period (2001 - 2015), while the standardized coefficient Beta was 0.075. Maximum temperature had a weak (0.168) positively significant relationship for the investigated period under study, minimum temperature had a weak (0.413) positive significant relationship which is more advisable and rainfall had the weakest (0.079) positive significant relationship and it cannot be held responsible for higher crop yield, except joined with other factors like soil fertility, soil moisture, soil PH and so on for the 15 years period. Tt was recommended that crops like eguisy should be planted in the month of February due to enough heat absorption so it could rapidly grow when the first or early months of rains start, and that Agricultural Extension Officers should be deployed to guide farmers through routine visits, sensitization programs on variability in rainfall and temperature characteristics, use of farm inputs and monitoring of crop-climate relationships in the area in order to achieve improved crop yield.

    APPRAISAL OF LAND USES IN FCT-ABUJA, NIGERIA
    (Department of Environmental Management, Nasarawa State University Keffi, 2021-08-08) Alkali, Mohammed; Anzaku, I.M.; Usman, Salihu Lay; Buba, Samaila
    Land is required for various uses in both the urban and rural areas. It is a major factor for production and vital element in the socio-economic development of any country. The study assessed land uses in FCT-Abuja, Nigeria. The study adopted both questionnaire and geospatial data analysis to achieve the stated objectives. A total of 600 copies of questionnaire were administered for the study. Land sal MSS, TM, ETM and Spot-5 satellite imagery of 1996,2000, 2008 and 2018 were used. Results showed that land uses such as agriculture, religion/institutional residential commercial/industrial have all recorded a positive magnitude change while land uses such as under developed. Social/recreational have recorded a negative magnitude change. For example, agricultural land use had increased from 6178.6 hectares to 13638.30 Hectares with a positive magnitude change of 7459.7 hectares and annual change rate of 497.3 hectares. However, social/recreational land use had declined from 7236; 10 hectares and annual change rate of-192.3 hectares. The positive changes in land use were due to rapid people perceived numerous court cases, lake of adequate security of tenure (encroachment), indeterminate boundaries, and inadequate security of tenure owners among others to be the constraints of land utilization in the study area. The study therefore recommended that land management should be decentralized at the local level to bring efficiency and accountability to the system. This would make procedures of land acquisition and registration easier and faster.

    Evaluation of the Effect of Depletion of Wetland for sustainability in Obeno LGA, Akwa-Ibom state, Nigeria
    (Department of Environmental Management, Nasarawa State University Keffi, 2021-06-06) Alkali, Mohammed; Anzaku, I.M.; Ntuk, Ernest E.; Usman, Salihu Lay
    The study assessed the effects of depletion of wetland for sustainability of Ibeno Local Government ofAkwa Ibom State. The specific key objectives of the-study were to investigate the respondent perception of wetland status in the study area, to examine the correlation between the wetland resources and per capita income of the respondents, and to examine the factors responsible for wetland depletion in the study area. These objectives were justified on the basis that, the perception of the implications of depleting wetland on rural sustainability is already taking global position, and which this research work has studied. For the purpose of collecting needful data, 160 copies of questionnaire were administered, and 150 were recovered using the systematic random sampling technique after the area had been stratified into three phases in accordance with the area council layout plan. Descriptive statistical techniques such as the simple percentages, table, and bar charts were used to present and analyze data in order to achieve the formulated objectives. Causal Analysis (PPMC) was also used to test the hypothesis. The study revealed the negative implication of wetland depletion and its impact on not just livelihood sustainability but also a collapsing ecosystem. The study further showed that the immediate beneficiaries of wetland resources were aware of the depleted state of marine resources. Upon empirical investigation, it was realized that the community dwellers were dissatisfied with the depleted state of their resources as they could recall loads of species of flora and fauna that are no longer seen within their environment and they now wipe for their lack of unsustainable usage, as well as their unaware state of mind over their depleted resources and its effect on them, their environment and their socio­ economic structure that is collapsing by the day. The study however recommended that, the level of establishment of oil companies and their associated activities on the wetland ecosystem should be minimized and regulated, the use of poisonous, toxic and harmful substances should be completely discouraged and heavy penalties be levied on them within the domestic fishing areas, and afforestation, reforestation and wetland ecosystem restoration programmes should be put in place for purpose of sustainable development.
