MODELLING PM2.5 SPATIO-TEMPORAL VARIATIONS OVER SELECTED CITIES OF NIGER DELTA REGION, NIGERIA

Abstract Fine particulate matter PM2.5 has attracted much attention both scientific and public, due to its effects on human health. This study used remotely sensed PM2.5 to model the spatial and temporal variation of PM2.5 concentrations across the cities of the Niger delta region of Nigeria. Aerosol Optical Depth (AOD) PM2.5 data for this study […]

URBAN EXPANSION AND LAND USE CHANGES IN AKURE, NIGERIA USING GEOSPATIAL TECHNIQUE

Abstract Akure became the administrative headquarters of Ondo State, Nigeria in 1976 and since then, it has witnessed rapid developmental changes in terms of physical landscape, city growth and urban sprawl. These agents of Land Use and Land Cover Changes (LULCC) are capable of creating environmental problems such as transportation, land degradation, pollution among others. […]

APPLICATION OF GEOGRAPHICAL INFORMATION SYSTEM FOR FLOOD VULNERABILITY MAPPING ALONG IKPOBA RIVER BENIN CITY, NIGERIA

In different regions of Nigeria, floods have increased dramatically, affecting millions of people and inflicting huge economic damage. Flood disasters can be attributed to the unnecessary risks people take when they encroach on floodplains. Flood hazard maps are important to integrate geospatial and temporal data in the same computational environment that allows risk assessment, modeling […]

ASSESSMENT OF RAINFALL VARIABILITY IN SOME SELECTED STATIONS IN NORTH EASTERN, NIGERIA

Abstract Rainfall has been widely studied in terms of distribution over space, time and trends including onset and cessation. In any regional study of agricultural production rainfall is therefore of fundamental importance. This is very useful for decision making in issues of food security and other sectors affected by rainfall. This study seeks to assess […]

EMPIRICAL ANALYSIS OF RICE YIELDS DETERMINANT USING REMOTE SENSING VEGETATION HEALTH CONDITION INDICES: CASE STUDY OF LAKE GERIYO, AKERRA AND TALATA-MAFARA, NIGERIA

Abstract This research focuses on the ability of remote sensing vegetation index acquired from the Landsat-8 operational land imager (OLI)/thematic infrared sensor (TIRS) and Satellite Pour l’Observation de la Terre (SPOT-6 and 7) HRV, HRVIR, HRG system as effective indicator to measure rice growing condition and predicting yield rate. The normalized difference vegetation indices (NDVI), […]
