The Ecological Footprint of a person is calculated by adding up all of people's demands that compete for biologically productive space, such as cropland to grow potatoes or cotton, or forest to produce timber or to sequester carbon dioxide emissions
ABSTRACT The adoption and sustained use of Integrated Aquaculture and Agriculture depends strongly on the perception of the farmers which in turn can be largely influenced by the socioeconomic attributes of the farmers. This study therefore examined the socioeconomic characteristics of fish farmers in relation to their perception and willingness to adopt integrated fish-rice and pig production system in south eastern Nigeria. Abia and Imo States were purposely selected for the study because...
ABSTRACT The study involved 16 yreaner crossbred (New Zealand White and Chinchila) rabbits of about eight weeks of a.fetz with initial average weight of 0.69 kg. The animals were offered a measured amount of their respective diets. The level of replacement of groundnut cake with Gliricidia leaf meal (GLM) were 0, 25 50 and 75%, to give four diets which were fed ad libitum throughout the experimental period of 35 days. The similar average daily feed intake of the rabbit fed 0, 25 and 50% GLM i...
Abstract Biological deterioration of wood is one of the major challenges on wood utilization especially in tropical countries like Nigeria. This is because of the favourable weather condition for the bin-deteriorating agents to thrive. This study is therefore carried out to investigate the biodegrading agents of logs in sawmills and planks in plank markets in Ibadan, Nigeria. Data for the study were collected using checklist, and laboratory examination of collected samples from decayed logs ...
ABSTRACT A 96 hour bioassay was conducted to determine the toxicity of cassava effluent to Claries gariepinus juveniles and its effects on the gills and liver as well as on some blood parameters such as packed cell volume (PCV), Red blood cells (RBC), White blood cells (WBC), Haemoglobin concentration (Hb) and their counts. Juveniles of C. gariepinus of the same age and size showed varying degrees of hyper-activity, mortality, stress and lesions to different concentration of cassava effluent...
Fish a good source of Protein is susceptible to contamination because of their soft tissues and the aquatic environment. They can be contaminated at any point from farm to fork via many means. It is a major public health concern that consumers assume that fish caught fresh from the wild or processed is totally safe. This study therefore seeks to evaluate the human safety in consuming freshly caught fish from dams in Ekiti State and processed fish from Ekiti environs by assessing and comparing...
ABSTRACT A total number of 60 Tilapia zillii specimens were collected from Egbe darn Gbonyin local government in Ekiti West for 25 days. Morphometric measurements taken in the laboratory include total length, standard length, body weight, body depth, dorsal fin length, caudal peduncle length, head length. fork length, and pre-dorsal fin length. Total number of 34 female Tilapia zillii were collected as 26 number of male Tilapia zillii were collected from the study area. The maximum total leng...
ABSTRACT Water quality is very important in the environment, because life depends on this, it's very good to check the quality of water time to time to check the rate at which it is been degraded. The objective of this work is to determine the physiochemical and heavy metal parameter of abattoir effluent to surface water and compare the standard to WHO. Two empty bottles were used to collect sample from the surface water, GPS was used to get the geographical coordinate and samples were taken ...
ABSTRACT This study examines the trends, onset, cessation and growing season of rainfall over Akure using data obtained from the archive of Nigerian Meteorological Agency (NIMET) Oshodi, Lagos, over the period of 1970-2005. Standardized Precipitation Index (SPI) was estimated from the available Rainfall records, Decadal analysis of Akure indicated 1991-2000as a wet decade, while 1981- 1990 was a dry decade. The onset and cessation dates were determined. The estimated parameters were subjecte...
ABSTRACT Flood risk assessment is an important component of risk management. This study aims to generate a GIS-based flood risk map that can facilitate proper planning of mitigation measures against future floods occurrences. This study uses GIS technique and remotely sensed data to assess the extent of urbanization in land use, and vegetation changes in Ado-Ekiti metropolis between 1986 and 2017. Digital Elevation Models (DEM), settlement maps and satellite imageries to assess the susceptibi...
ABSTRACTDrought is one of the a resultant effect of climate change and it is the naturally occurring phenomenon that exists when precipitation has been significantly below normal recorded levels, causing serious hydrological imbalances that adversely affect land resource production systems. Unlike many other natural hazards, drought develops slowly, making it difficult to pinpoint the onset and termination of an event. The environmental impacts of hydrological drought are Reduced stream flow ...
ABSTRACT Precipitation deficit and its daily, seasonal and annual oscillations are inherent characteristics of Nigeria's climate. Droughts are generally characterized by a prolonged and abnormal moisture deficiency. In drought studies it is important to characterize the start and end of a drought as well as its intensity, duration, frequency and magnitude. The objective of this study was to apply the Standardized Precipitation Evapotranspiration index (SPEI) for drought assessment in the Be...
Abstract The Information on the effect of different land use systems on the aggregate stability and carbon sequestration is crucial for the recommendation of efficient land management practices. This study was conducted to evaluate the variation in aggregate stability and carbon sequestration under different land use systems in two agro ecological zones of south eastern Nigeria. The agro ecological zones were derived savannah and rainforest while the land use systems studied were cultivate...
ABSTRACT Cadmium (Cd) is a common environmental contaminant found in soils. Unlike other metals. Cd has no biological role, and is potentially toxic to microorganisms. The concentrations of cadmium in agricultural soils depend upon the amounts present in the parent rocks from which the soils form, the amounts added in the form of fertilizers and soil amendments, the amounts deposited onto soils from the atmosphere, and the amounts removed by harvested crops and by leaching. Its aim was t...
ABSTRACT Water is an important resource for almost all human activities like agriculture, industry, transportation, domestic uses and the proper functioning of the human body, The study examined the physiochemical properties and potentially toxic metals in hand-dug wells and boreholes in Ikole Ekiti and its Environs. Six functional hand-dug wells and six boreholes in the area were sampled and analyzed using standard procedures. Potential toxic metals were determined using Atomic Absorption S...
