Managing Land Use Transformation and Land Surface Temperature Change in Anyigba Town, Kogi State, Nigeria

Abstract

The uncontrolled urban growth in cities comes with unattending alteration in the urban environmental system. This alteration as land use types change is most responsible for some of the problems witnessed in urban town such as the variation in land surface temperatures over time. This study used Remote sensing and GIS techniques to identify, mark and measure the extent of the various land uses from the Landsat TM image of 1995 and Landsat ETM+ image of 2006. The study revealed that the spatial and temporal changes in the land uses have greatly influenced the increase in the land surface temperature of each of the identified land uses. As vacant land and built-up area increased by 3.28 ha/yr and 78.34 ha/yr so did their land surface temperature increased by 0.083 o C/yr. While vegetation and water and wetland vegetation decreased, their respective land surface temperature increased by 0.075 o C/yr and 0.083 o C/yr. This increase in land surface temperature of the study area within the period of study suggest that the rise in temperature of the various land uses may encourage environmental problems associated with local climate change as heat waves and mosquito infestations which can cause human discomfort as its been witnessed today in Anyigba. Proper checks on the development and conversion of land uses, urban forestry and adequate planning if employed may help in managing this occurence from agravating other environmental problems associated with land uses change and climate change.

Physiological Response of Broiler Chickens to Varying Dietary Levels of Scent Leaf (Ocimium Gratissimum) Meal

“…Scent leaf (Ocimum grattisimum) meal was incorporated at 0 %, 0.45 %, 0.75 % and 1.05 % and designated as T1, T2, T3, and T4 respectively. Each treatment had twenty-four birds (24) with three replicates of eight (8) birds each The birds were raised on deep litter system. The experiment lasted for four weeks.…”

Serum biochemistry and haematological indices of finisher broilers fed varied levels of frog (Rana esculenta) meal as a replacement for full fat soybean

“…Anyigba is situated between Latitude 7º 15' and 7º 29'N of the equator and Longitude 7º 11' and 7º 32' E of the Greenwich meridian and with an average altitude of 420metres above the sea level. Anyigba town falls within the tropical wet and dry climate region of the Guinea savanna, with average annual rainfall of 1600mm and daily temperature range of about 25 ºC -35 ºC [14]. The dried frogs were ground and stored in airtight containers pending the time of its use as a partial replacement for soybean.…”
