One of the anthropogenic interference is the modification of natural habitat into the man-made environment, such as agriculture, urbanization mining, lumbering as well as industrialization. The kenyir lake as an artificial lake, attract tourist from all over the world because of its natural beauty sustainable development an eco-tourism attraction. This study will focus on how the natural landscape will be conserved and what is the composition of the land cover surrounding the Lake kenyir. The current issues that course for concern are the changes observed and detected from the land use, land cover (LULC) through the use of soil water assessment tool (SWAT) ArcSWAT 2012. The study area was finally characterized by a delineated watershed, sub-basin parameters for calculation of hydrologic response units (HRUs). this includes the nature and orientation of the slope; digital elevation model (DEM), local soil classification and the land cover found around the environment. The 3D simulation was applied to predict the flow of water from the subbasins and from the lake that drained into a larger body of water toward the river mouth of Kuala Terengganu to empty into the South China Sea.
One of the determinants of people’s numbers is the socioeconomic prosperities of a particular place in the context of population census. The population is defined as the total number of people, animals and other variables per unit area in the environment. This study focuses on the negative and positive aspects of population growth and distribution. The study also covers possible factors influencing population growth and distribution in Mararaban Guruku, Karu Local Government Area of Nasarawa State. The data presented were obtained from the National Population Commission with a focus on socio-economic data and made use of appropriate statistical analysis of coefficient of determination (R2). Almost all the models have a strong and significant correlation. The multiple regression analysis defined the fitness the model at 0.9 and 0.8. The result indicates positive correlation of dependency ratio and strong impact on population increase. Mararaban Guruku is considered to have high population growth and subjected to negative influence population change ranging from high crime rate, growth of urban slums and ghetto, unemployment and overcrowding. However, it is suggested by the respondents that people are becoming aware of the use of family planning as an effective avenue of Birth control.
The knowledge of exposure of croplands to climate variability is of paramount importance in adaptive capacity planning to boost food production for the world’s growing population. The study assessed the exposure of croplands to climate variability in the Federal Capital Territory (FCT) of Nigeria using Geo-informatics. This was achieved by examining the distribution pattern of climate indices in FCT from 1981-2017, determining the exposure index of croplands in FCT Area Councils and production of exposure map of FCT Area Councils, The spatial scope of this study is the entire arable land in FCT which is made up of six Area Councils. The research is contextually restricted to exposure of croplands to climate variables while other variables remain constant. The selected climatic variables are rainfall, temperature, relative humidity and potential evapotranspiration (exposure indicators). The arable crops in focus are yam, beans and maize while the soil variables selected for the study are: soil erosion, organic carbon content of the soil, clay content of the soil and percentage of arable land available for crop production. The temporal scope of the examined exposure indicators (climate variables) was limited to a period of thirty (37) years from 1981- 2017. The result indicates that Bwari has the highest exposure (0.1671) to climate variables while Abaji has the least (0.0868) exposure. AMAC is high (0.1371), Kuje (0.1304) is moderate while Gwagwalada (0.1132) and Kwali (0.1154) have low exposures to climate variability. The implication of this on the referenced crops is that crop yield will be highly reduced in Bwari and optimum in Abaji Area Councils due to their climatic requirement. The power of Geo-Spatial Technology in combining different indices of exposure to produce exposure map was demonstrated in the study.
Despite the wide coverage of study on vulnerability in the Federal Capital Territory (FCT) of Nigeria over the years, it was observed that no emphasis has been placed on assessment of vulnerability of croplands to climate variability using the integrated vulnerability assessment and Geo-Informatics technique. This was achieved by determining the climate variability pattern in FCT from 1981 to 2017, determining the exposure index and the degree of sensitivity of croplands to climate variability, assessing the adaptive capacity of farmers to climate variability, evaluating the vulnerability of croplands to climate variability and developing vulnerability maps of croplands using the information produced. Yam, beans and maize were used as referenced crops in this study. Indicators were generated and analyzed on the three components of vulnerability: exposure, sensitivity and adaptive capacity. The study used the mixed research design. The Analytical Hierarchy Process was used to assign weight to the indicators. The weights were used to generate the exposure, sensitivity and adaptive capacity indices which were used to generate the vulnerability index map. Aggregate vulnerability index (AVI) was finally determined from the weighted sum of all indicators and used to produce the vulnerability map of the six Area Councils. The study shows that Gwagwalada Area Council has the highest vulnerability (0.2323) and Abaji Area Council has the lowest (0.005). Kwali and AMAC Area Councils were highly vulnerable to climate variability (Kwali 0.1562, AMAC 0.1565). Kuje Area Council has low vulnerability (0.0273) to climate variability. Bwari Area Council showed moderate vulnerability (0.0982). The implication of the results is that the three crops (maize, beans and yam) will produce moderately at moderate vulnerability while their production will be marginal and optimal at very high and very low vulnerabilities respectively. Crop production will be optimum in Abaji, marginal in Gwagwalada and moderate in Bwari. The study also revealed that vulnerability assessment is essential in determining the varying degrees of vulnerability in different localities. It also provides information that can help researchers, policy makers, private and public institutions in planning location-based adaptation strategies and prioritizing allocating limited resources in FCT. Agriculture should be heavily subsidized in terms of providing irrigation infrastructure to farmers to reduce over-reliance on rain fed agriculture. Installation of early weather warning system manned with expertise should be made available in all the Area Councils to provide timely and accurate climatic information to farmers.
The future of climate lies on the hand of individual who is an active member that contributes input in the biosphere. The amount of climate change will largely influence the water flow in the river through the emission of solar radiation, increase in temperature, heat-trapping gases. There is a need to control pollution, flood hazard, check water quality and monitor sediments and water flow in the drainage basin. Soil and Water Assessment Tools SWAT is one of the best methods of the application being used for hydrologic assessment as well as monitoring events that occur in the catchment studies. Mitigation can simply determine how to reduce the human hazard, in controlling the climate change that affects water flow in river Terengganu. The Soil Water Assessment Tool (SWAT) provides the simulated rainfall from 1973 to 2017. The precipitation and other weather parameters were used for the purpose of this study and the resultant effect is the production of predictive flood hazard event within the catchment area of Kuala Terengganu.
