Abstract This study examines the morpho-tectonic settings of the drainage system in the northwestern Ethiopian plateau by focusing on the Tekeze River. The plateau is underlain by Precambrian crystalline rocks, overlain by EOCENE and Late Oligocene basalts. An attempt is made to study the underlying geology of Tekeze river basin and its significance in morphometry […]
RATE OF LAND COVER CHANGE AND ITS DETERMINANTS IN THE SOUDANO-GUINEA TRANSITION ZONE OF BENIN REPUBLIC
Abstract The paper assesses land cover dynamics and its associated drivers in the soudano-guinea transition zone of Benin Republic, using both spatial and non-spatial data. Multispectral and multi temporal Landsat imageries (Landsat TM of 1986, ETM+ of 2000 and OLI-TIRS of 2013) were used for the analysis of land cover dynamics through a supervised classification. […]
HEALTH RISK OF HEAVY METALS IN Celosia argentea L. GROWN ON MUNICIPAL WASTE SOILS IN IBADAN, NIGERIA
Abstract This paper assessed the appropriateness of dumpsites in Urban and Peri-urban Agriculture (UPA). The bioaccumulation and potential heavy metal-toxicity risk of consuming Celosia argentea L. grown on four different dumpsites soils (Ajibode, Sasa, Moniya and Akinyele) and reference soil from University of Ibadan Training and Research Farm was also evaluated. The soil samples were […]
ANALYSIS OF MONTHLY RAINFALL VARIATIONS: FURTHER EVIDENCE OF CLIMATE CHANGE IN SOKOTO STATE, NIGERIA (1926-2015)
Abstract The concern for climate change had led to an upsurge in climate research with most of such efforts concentrated on rainfall. The thrust of such studies showed that annual rainfall series was on the decrease in most parts of the Sahelian region of Africa since late 1960s with a slight recovery from the year […]
FACTORS INFLUENCING WILLINGNESS TO PAY FOR IMPROVED URBAN SERVICES IN SELECTED SLUM COMMUNITIES: EMPIRICAL EVIDENCE FROM LAGOS MEGACITY
Abstract The diminishing resource-capacities of governments for intervention-cum-development purposes vis-à-vis the threats of exacerbating degeneration of existing slums, driven by uncontrollable influx of immigrants, motivated this research. It analyses the factors of willingness to contribute diversely to improve urban service provision in selected slum communities of Lagos Megacity. Cluster sampling technique was used to identify […]
TIME SERIES MODELING OF THE DISTRIBUTION OF MONTHLY RAINFALL IN HAWASSA CITY, ETHIOPIA
Abstract Rainfall is the most key variable both in atmospheric and hydrological cycle. Its patterns usually have spatial and temporal variability. This variability affects agricultural production, water supply, environment, and the existence of its people. Its variability assumed to be the main cause for the frequently occurring extreme events such as drought and flood. The […]
