The study utilized Landsat imageries of 1987 (Landsat Thematic Mapper (TM)), 2000 (Landsat Enhanced Thematic Mapper plus (ETM+)) and 2014 (Landsat Operational Land Imager (OLI)) to examine land transformation in the Gashaka-Gumti National Park. The analysis indicated that dense forest which occupied 367,500 hectares at 62.2% of the total area of the park in 1987 has been converted into farmland and built-up area. Thus, the dense forest has reduced to 343, 300 hectares by the year 2000 and 107, 600 hectares in 2014 respectively. The result shows that the riparian forest decreased from 21,300 hectares in 1987 at 3.6% to16, 000 hectares in 2000 at 2.7% and further to11, 000 hectares (1.8%) by 2014. Savannah vegetation found to be concentrated in the northern part of the study area and occupied a total area of 81,260 hectares at 13% in 1987, reduced to 62,100 hectares at 10.5% in 2000 and increased to 183,800 hectares at 31.1% of the total area in 2014. The built-up area occupied a total area of 4,476 hectares at 7.5% in 1987. The built-up increased to 11,070 hectares at 1.81% in 2000 but decreased to10.930 hectares at1.85% in 2014 as a result of the news that the insurgents were shifting their base towards the park to hide from security forces and some of the people living within the area became afraid and deserted their houses and resettled in the nearby towns and villages that are outside the park.

This research work is aimed at the effects of deforestation on the economic activities of the inhabitants of Abaji area in Abuja. The study employed a mixed research strategy in the collection, analysis and presentation of findings. The tools of data collection include administered questionnaires and participant observation and reconnaissance survey carried out in the study area to gather baseline information which would aid the design of the study. Information accessed during the visit includes the baseline report on problems encountered with deforestation in Abaji area. Personal interview was conducted to some selected individuals living in Abaji area wards such as agricultural officials or extension workers, farmers, household heads, fuel wood seller and people working at the timber sheds. Questionnaires based on socio-economic characteristics of the households were administered. The questionnaire was administered to meet the stated objectives of the study. Six (6) wards were sampled using stratified random sampling technique. In this situation, the Area Council was stratified into North, Central and Southern zones. 140 households were sampled. Out of 300 respondents sampled in this study, 67.3% are male while 32.7% are females. Most respondents interviewed had some form of education indicating that there is generally fairly literacy level among them except for 9% that have no formal education. The result of the study has clearly indicated that the occupation distribution of 51% of the respondents is farming. Apart from farming, other forms of occupation such as driving, tailoring, lumbering and trading constitute 28% of the response obtained. On the other hand, gathering of fuel wood, collection and gathering of medicinal plants, collection of wild fruits and nuts, collection of wild vegetables, and gathering of fodder, marketing of bush meat etc. constitute 22% respectively. By implication, this means that the bulk of the responses are directly involved in activities that cause deforestation. The study recommends that deforestation effects could be ameliorated by promulgation of government policies that regulate the use of forest products, dissemination of information on forest, environmental sustainability issues, and education on aforestation in order to improve and maintain farmlands, since agriculture has been implicated as one of the primary causes of deforestation, there is need to adopt farming systems that encourage conservation tillage. This should include introduction of organic farming method, hydroponics, greenhouse gardens, slash and char rather than slash and bum, as well as alley farming in which crops are interspersed with small trees.

A Campus guide map for Taraba State University Jalingo was produced. The data source for the study includes satellite images of the study area and field survey using a GPS device to collect coordinates of major ground control points. This research incorporated the use of geospatial techniques and functionalities such as georeferencing, digitizing and geo-database creation to generate a campus guide map. The findings of this study reviewed that most of the structures and roads are not adequately labeled or named for easy navigation. The study also showed that development is confined mostly to the North Western and southwestern part of the campus.           We recommend structural planning and spatial development within the campus land cover in the future.
