Published: April 20, 2023

This paper addresses the issue of satellite image processing using GRASS GIS in mangrove forests Niger River Delta, southern Nigeria. The estuary Delta Gulf Guinea is an essential hotspot biodiversity on western coast Africa. At same time, climate issues and anthropogenic factors affect vulnerable coastal ecosystems result rapid decline habitats. motivates monitoring vegetation patterns advanced cartographic methods data analysis. As a response to this need, study aimed calculate map several indices (VI) scripts as programming integrated geospatial studies. include four Landsat 8-9 OLI/TIRS images covering segment Bight Benin for 2013, 2015, 2021, 2022. techniques included ’i.vi’, ’i.landsat.toar’ other modules GIS. Based ’i.vi’ module, ten VI were computed mapped estuary: Atmospherically Resistant Vegetation Index (ARVI), Green (GARI), (GVI), Difference (DVI), Perpendicular (PVI), Global Environmental Monitoring (GEMI), Normalized Water (NDWI), Second Modified Soil Adjusted (MSAVI2), Infrared Percentage (IPVI), Enhanced (EVI). results showed variations habitats situated over last decade well increase urban areas (Onitsha, Sapele, Warri City) settlements State due urbanization. analysis enabled us identify visualize changes patterns. technical excellence was demonstrated used study.

Detection of changes in the hydrobiological parameters of the Oder River during the ecological disaster in July 2022 based on multi-parameter probe tests and remote sensing methods

Ecological Indicators, Journal Year: 2023, Volume and Issue: 148, P. 110103 - 110103

Published: March 8, 2023

Starting from the second half of July, hydrological conditions (low water levels and low flows) atmospheric (high temperatures, lack precipitation) contributed to algae bloom in Oder River basin. The mass extinction fish middle lower section was probably result such environmental conditions. Because is correlated with an increase content chlorophyll river on its surface, authors focused analysis changes amount longitudinal profile river. key data obtained by soundings carried out at interval about one kilometre during research expedition, which took place July 16–24, 2022. These coincided values NDVI index (normalised difference vegetation index) based 10-metre satellite images Sentinel 2 mission. Imagery cloudless periods (mainly March, June, August) processed using compared. Regularly elevated upstream (occurring each period) temporarily as moving downstream were observed. This article confirms initial conclusions Kolada et al.

Abstract In precision agriculture, it is possible to use satellite monitoring of fields. Satellite systems allow you get free images with a resolution up 10 m per pixel, which sufficient determine the state vegetation plants on such indicators as normalized index NDVI. However, NDVI indicator already indicates existing problems correction will not help restore lost yield crops, but only helps prevent further losses. Using NDSI soil salinity index, difference in its properties from spectral images. Also, can study early stages their development, fact immediately after germination. Soil-adjusted MSAVI, used for this purpose. Studies indicate possibility using and MSAVI diagnosis confirmed crops NDRE (indicating chlorophyll activity plants) at later development. conducted soybean, spring barley maize sown 2021 correspondence between raster field maps show-ing above indices made March July. Statistical analysis specialized software showed correlation May, respectively, indexes June Therefore, judge expediency plant vegetation, well creation differential fertilization.

The insinuations of the ailments associated with unrestrained and disorganized proliferation artificial impervious materials over natural surfaces are prevalent among city dwellers. These impacts can be comprehended by estimating land surface temperature (LST), as it is vital for evaluating urban climate, particularly to explain intensity heat islands define health welfare planet well living beings. Urbanization-driven landscape changes severely disrupt comfortable in almost every city, necessitating monitoring modelling historical, current, likely future LSTs. This research article proposes two forecasting techniques: Multiple Linear Regression (MLR) Artificial Neural Network (ANN) models. models have been widely accepted efficient prediction climatic parameters, including LST, an area. landscape, elevation, LST trend served input accurate LST. analysis was performed Kolkata Metropolitan Area (KMA) additional 10 km buffer understand growth its effect on entire region. developed (MLR ANN) effectively anticipated KMA A continual increment temperatures ranging from 1 °C 4 °C, existing likely-predicted areas comprehended.

The sustainable building concept must be implemented throughout the project lifecycle to achieve highest proceeds without lowering standard. Although implementing green walls in emerging nations is partial, such studies have concentrated on drivers for walls. Conversely, there less proof comprehensively study impact of walls’ overall success (OSS) concerning projects. This research focuses wall adoption barriers construction projects third-world nations. It assesses effect addressing (GW) obstacles OSS lifespan. Therefore, a broader review literature needed conceptual model development. Structural equation modelling and partial least square (SEM-PLS) been developed employing survey evaluation tool (i.e., questionnaire). Information was derived from one hundred five professionals Nigeria. output revealed that eradicating GWs had slight intermediate influence during scheme’s These results offer foundation policymaking regarding successful completion through evading adoption.

The results indicated built‐up index (BI) and area (BU) indices experienced significant growth, increasing by ~157.5% 38.91%, respectively. In contrast, normalized difference water (NDWI) exhibited negative trend, decreasing ~61.2%. base year, man‐made accounted for ~20% city’s area. By 2022, this proportion had risen ~76%, reflecting an impressive growth rate 230.4%. increase demonstrated strong positive correlation with BI BU at confidence levels 0.01 0.05. Furthermore, LST rose from ~35.55°C year ~38.91°C 2022. trend relationship hot season temperature, yielding coefficient 0.760 error level trends were consistent across various areas. Geographically weighted regression (GWR) analysis yielded R 2 value 0.7835 adjusted 0.7712. multivariate four indices—temperature station, NDWI, BI, urban—were associated 95% level.
