Land Use/Land Cover (LULC) changes alter the ecosystem structure and function, resulting in variations of Ecosystem Service Values (ESVs). This study investigated impacts LULC on ESVs over 37 years Cherangany Hills Water Tower (CHWT) Kenya. Landsat images from 1985 2022 were used to examine historical CHWT. Supervised classification was carried out using Random Forest (RF) classifier R-Studio while ArcGIS desktop software for mapping evaluate changes. Accuracy assessments also conducted each...
Abstract As an effect of forest degradation, soil erosion is among Ethiopia’s most pressing environmental challenges and a major threat to food security where it could potentially compromise the ecosystem functions services. effects intensify, landscape’s capacity support services compromised. Exploring ecological implications crucial. This study investigated loss land degradation in Lake Abaya catchment explore landscape restoration (FLR) implementation as possible countermeasure effects....
Climate variability impacts various global challenges, including food security, biodiversity loss, water scarcity, and human well-being. However, climate patterns trends community perceptions at spatially-explicit levels have been minimally addressed. The spatial temporal of conditions in Bagamoyo District Tanzania were examined using historical (1983–2010) projected (2022–2050) meteorological model data, respectively. Community knowledge experiences past occurrences included. implications...
This study employed Remote Sensing and Geographical Information Systems to explore the influence of environmental factors human-induced land use/land cover changes on chemistry soda-saline lakes in Northern Tanzania. Satellite-based rainfall data were sourced from Climate Hazards Group Infrared Precipitation with Station (CHIRPS) datasets, temperature obtained MERRA-2. Monthly precipitation, temperature, drought conditions lake watersheds analyzed 1981 2022, while use assessed for 2000,...
The central highlands of Kenya play a vital role in supporting agricultural activities and sustaining the livelihoods smallholder farmers. Despite its crucial role, region faces substantial environmental challenges like soil erosion land degradation, necessitating adoption sustainable management practices. aim this study was to investigate determinants Soil Water Conservation Practices (SWCPs) among farmers Kenya. Primary data collected from three administrative wards Tharaka Nithi County...
Abstract Land use and land cover (LULC) change remains a major concern in many countries. To examine how is used for increased actions on forest landscape restoration (FLR) issues, this study analyses LULC changes from 1991 to 2022 predict future patterns the years 2050 Tchamba Prefecture, Togo, using remote sensing Cellular Automata-Markov modelling technique. Results show that dense forests gallery (18.85%), open forest/woodland (20.17%), tree shrub savannah (50.04%) were predominant...
Abstract Maize production in low-yielding regions is influenced by climate variability, poor soil fertility, suboptimal agronomic practices, and biotic influences, among other limitations. Therefore, the assessment of yields to various management practices is, others, critical for advancing site-specific measures enhancement. In this study, we conducted a multiseason calibration evaluation DSSAT–CERES-Maize model assess maize yield response two common cultivars grown Trans Nzoia County Kenya...
Abstract Population growth and increasing demand for agricultural production continue to drive global cropland expansions. These expansions lead the overexploitation of fragile ecosystems, propagating land degradation, loss natural diversity. This study aimed identify factors driving use/land cover changes (LULCCs) subsequent expansion in Trans Nzoia County Kenya. Landsat images were used characterize temporal LULCCs 30 years derive using change detection. Logistic regression (LR), boosted...
Abstract Maize ( Zea mays L.) productivity in Kenya has witnessed a decline attributed to the effects of climate change and biophysical constraints. The assessment agronomic practices across agroecological zones (AEZs) is limited by inadequate data quality, hindering precise evaluation maize yield on large scale. In this study, we employed DSSAT‐CERES‐Maize crop model (where CERES Crop Environment Resource Synthesis DSSAT Decision Support System for Agrotechnology Transfer) investigate...
Abstract Agricultural production assessments are crucial for formulating strategies closing yield gaps and enhancing efficiencies. While in situ crop measurements can provide valuable accurate information, such approaches costly lack scalability large-scale assessments. Therefore, modeling remote sensing (RS) technologies essential assessing conditions predicting yields at larger scales. In this study, we combined RS a growth model to assess phenology, evapotranspiration (ET), dynamics grid...
Abstract The Mount Kenya forest ecosystem (MKFE), a crucial biodiversity hotspot and one of Kenya’s key water towers, is increasingly threatened by climate change, putting its ecological integrity vital services at risk. Understanding the interactions between extremes dynamics essential for conservation planning, especially in Forest Ecosystem where rising temperatures erratic rainfall are altering vegetation patterns, reducing resilience, threatening both security. This study integrates...
Understanding how elevation gradients and soil depths influence organic carbon stocks (SOCS) total nitrogen (TNS) is essential for sustainable forest management (SFM) climate change mitigation. This study investigated the effects of depth on SOCS TNS in Mount Kenya East Forest (MKEF). A stratified systematic sampling approach was applied, involving collection 38 samples from two (0–20 cm 20–40 cm) across three zones: Lower (1700–2000 m), Middle (2000–2350 Upper (2350–2650 m). Samples were...
Abstract: Long-term rainfall, temperature and solar radiation time series data are required to simulate crop yield variability. A field experiment conducted at Mount Makulu was used the interactive effect of planting dates (SD1, SD2, SD3), maize varieties (PIO30G19, PIO30B50, ZMS606), nitrogen fertilizer application levels (N1 = 66; N2 132; N3 198 kg N ha-1) on strategic economic assessment. Statistical downscaled climate datasets from three GCMs 1971-2000, 2010-2039, 2040-2069, 2070-2099...
