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...
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,...
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....
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...
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...
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 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 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: 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...
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...
Understanding the influence of land use and elevation gradient on soil organic carbon stocks (SOCS) is essential for effective management, sustainable agricultural practices, mitigation climate change impacts. This research aimed to explore how types gradients SOCS eastern slopes Mount Kenya. Using a stratified systematic sampling approach, 68 samples were collected from 0–20 20–40 cm depths, representing forestland farmland, across six ranging 1000 2650 m above sea level (a.s.l.). Soil...
This study was aimed at assessing soil erosion, climate variation and how has affected both the agro climatic agro-ological zones of Kerio Valley basin. The basin faces challenges especially loss, due to massive degradation that takes place in valley. Due increase rainfall recently experienced area, most top been carried away leading excessive valley, causing loss subsequent deposition sediments Lake Kamnarok which is an oxbow lake posing it threat extinction. All these aforementioned...
Rural households in Tanzania and Mozambique depend mainly on charcoal, firewood other traditional fuels, such as cow dung or agriculture by-products, to cook. Simultaneously, fuel scarcity is an important phenomenon that leads apply coping strategies reducing the number of meals increasing walking distance collect firewood. Despite well-known negative health, economic potential ecologic impacts, transition away from solid biomass energy sources not expected short run. Thus, understanding...
Changes in Land Use/ Cover (LULC) due to anthropogenic and natural drivers alter the ecosystem structure function, resulting 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 examine historical land cover changes CHWT.
