“…To improve the quality and fertility level of the soils in these locations, Onwudike et al (2016) recommended urgent need to adopt strategic management measures and agronomic principles that will improve the fertility levels. Likewise, in a study reported by Aliyu and Ray (2014), on the comparative study of soil fertility rating under crop cultivation in Gombe, it was reported that under groundnut farm, available phosphorous rated as moderately low has the mean value of 29 ppm which scores three marks, while organic carbon, exchangeable Na, Ca, and CEC are rated as very low. This variable has the mean of values 0.85, 0.88, 4.93 and 6.25 respectively which scored two marks.…”

A number of Nigeria's natural resources are being depleted at very fact rates, making their availability unsustainable for sustainable industrial development. The Nigerian soils are generally light texture and low in Cation Exchange Capacity (CEC) which ranged from 2.40 to 5.95 mc/100g of soils. Various soil fertility studies have shown that most Nigerian soils have pH ranges from 4.2 to 8.4 with a combined calcium content which varies from 0.5 to 5.55nc/100g and generally low potassium content (0.07 to 0.45) and an organic matter that varies from 1 to 2.55%. The level of micronutrients are low with fertility and productivity indices varying between 31-90% and 2-58% in most cases. Soil fertility and nutrient content are fast depleting by various factors which includes low use of mineral fertilizers, gully erosion, soil salinity, desert encroachment and others such as inappropriate agricultural practices, oil spillage, over population and lack of land use planning. Also, on the increase is groundwater depletion, deforestation which occurs at about 300,000-400,000ha per annum, loss of biodiversity which is threatening 484 plant species in 112 families of the 4,600 plant species in Nigeria. Fisheries resources are also depleting. Both the inland freshwater and the oceans are experiencing serious onslaught of the fish population with species such as the Atlantic cod and haddock already depleted in the salt waters. On the inland waters, fish production is being decimated on annual bases with production in the 80's less than half of the 1950's. The mineral resources have been mined since 1906. Currently, large scale exploration of limestone, marble, rock aggregates along with gold, oil and gas are on-going causing a lot of havoc to the environment. There is need to halt or reduce these occurrences in order to put industrial development on a sustainable path.

Demographic and socio-economic developments couple with other requirements to satisfy human needs result in rapid urban expansion sometimes with increasing rate of surface extent greater than the rate of growth of population, that result in continuous sealing of ground surface thereby affecting ecosystem services. This study applied remote sensing toward achieving the progress of SDGs and stage to determine the ratio of the rate of land consumption to the rate of population growth of Gombe metropolis. QGIS 2.18 was used for the image processing and classification analysis for the key Landsat ETM+ (Enhanced Thematic Mapper), Impervious Surface Indices and population data to inform on the urban trend and LCR/PGR for the periods 2000-2005, 2005-2010, and 2010-2015. The result appears that the LCR/PGR for the periods of study show split trends. During 2000-2005 the result shows that the study area expanded outward with LCR/PGR of 1.2. The result also indicate that during 2005-2010, the study area densified with little expansion with the LCR/PGR of 0.8. The result further reveals that during 2010-2015 the LCR/PGR reached 1.8. Pointing that the study area expanded outward with the rate of ground sealing getting high.
