Green areas, thanks to their relatively unified natural systems, play several key roles. They contribute the proper functioning and sustainable development of cities also determine quality life for inhabitants. As a result, urban planners policy-makers frequently aim maximize benefits green spaces by creating various programs strategies focused on infrastructure development, such as City initiative. One objectives this program is create new parks. This research focuses developing method selecting sites parks, taking into account factors related environment, accessibility, human activity. The was carried out area Ciechanów city. To make city areas more attractive residents, authorities increase revitalize existing greenery. combination Fuzzy AHP fuzzy set theory (selecting appropriate membership each factor), along with use large diverse geospatial datasets, minimized subjectivity in prioritizing criteria allowed fully automated analysis process. Among analyzed, land emerged most significant, followed normalized difference vegetation index (NDVI) proximity surface water. results indicated that 16% deemed highly suitable park while 15% considered unsuitable. One-at-a-time (OAT) sensitivity analysis, based changes weight land-use factor, revealed 75% reduction resulted nearly 57.2% decrease unsuitable led 40% expansion locations. potential locations were compared heat map activity developed contributes discourse transparency location decisions validity used, promote provides residents access active recreation.

Flood Risk Assessment and Zoning for Niamey and Lokoja Metropolises in Niger and Nigeria

Hydrology, Год журнала: 2025, Номер 12(1), С. 17 - 17

Опубликована: Янв. 15, 2025

With the increasing frequency of floods in recent decades, particularly West Africa, many regions have faced unusual and recurrent flooding events. Communities flood-prone areas experience heightened insecurity, loss property, and, some cases, serious injuries or fatalities. Consequently, flood risk assessment mitigation become essential. This comparative study between Niamey Lokoja employs Geographic Information Systems (GIS) Analytical Hierarchy Process (AHP) to delineate susceptibility, vulnerability, zones. The utilized a comprehensive range thematic layers, with weight percentages assigned each parameter as follows: 29% for elevation, 24% slope, 15% Topographic Wetness Index (TWI), 9% drainage density, distance from rivers, 4% both precipitation Normalized Difference Water (NDWI), 2% Vegetation (NDVI) soil type. To validate these weightings, consistency ratio was calculated, ensuring it remained below 10%. findings reveal that 32% area is at flooding, compared approximately Lokoja. results highlight very high potential, near Niger River, this potential decreasing elevation increases. Given current prevalence extreme weather events crucial employ effective tools mitigate their adverse impacts. research will assist decision-makers quantifying spatial vulnerability developing strategies region.

Quantifying Climate Change Impacts on Hydrological Dynamics and Sedimentation Using GIS and SWAT+ Modelling

Hydrological Processes, Год журнала: 2025, Номер 39(2)

ABSTRACT Climate change significantly impacts natural hydrological systems worldwide, affecting water availability and sedimentation dynamics. The upper Indus Basin is one of the most crucial basins in South Asia, which undergoing severe climatic variations, resulting extreme flooding. This study examines impact climate on cycle, availability, dynamics Shyok River basin Karakoram region. focuses investigating increasing outflows a seasonal basis, as found previous studies, by utilising daily river discharge data between 2003 2014 at Yugo hydrographic station operated WAPDA with geographic information (GIS), SWAT+ (Soil Water Assessment Tool), remote sensing, statistical techniques. To analyse variables, using only available ground weather stations inside basin, we have utilised ERA 5 reanalysis dataset to evaluate precipitation temperature trends. significance ERA5‐derived variables has been assessed Mann‐Kendall test, Sen's slope analysis Coefficient Determination R 2 from 2000 2020 monthly basis.

Food Safety Monitoring Indicators and Early Warning Level Setting Based on Time Series Analysis

Applied Mathematics and Nonlinear Sciences, Год журнала: 2025, Номер 10(1)

Опубликована: Янв. 1, 2025

Abstract In the context of globalization, food safety has attracted much attention and become one focuses social concern. This study constructs setting monitoring indicators early warning levels based on time series analysis in order to realize finger improve efficiency accuracy management. Taking infant milk powder as a specific research object, hierarchical method is first improved by using three-scaled selection weight determination indexes construct comprehensive index function safety. Then, data, corresponding composite obtained. The prediction effects ARIMA model quadratic exponential smoothing are explored, level set appropriately. relative absolute errors range [0.02%, 0.99%] [0.0004,0.0125], which smaller than that ARMA(2,1,1) model, indicating more effective prediction. Thus, this paper chooses constructed for sets 0.7. provides new solution warning.
