Abstract:

In recent decades, due to rapid human population increases and in its results, destructive effects of anthropogenic activities on natural resources have become a great challenge. Land use and vegetation are important factors in soil erosion and runoff generation. This study was performed to assess the effects of different amounts of forest cover on the control of runoff and soil loss in the Talar basin, which is located in Mazandaran province, using a runoffrainfall model, geographical information system (GIS) and remote sensing (RS) to determine the hydrologic effects of deforestation on the Talar watershed (north of Iran). A runoff-rainfall model has been presented using GIS (HECGeoHMS) and hydrologic model (HEC-HMS). Land use changes (deforestation) and anthropogenic activities (roads and impervious surfaces development) were evaluated using RS techniques and satellite images. We used the Soil Conservation Service and Curve Number methods for hydrograph simulation and runoff estimation, respectively. First, a model was performed and optimized. Afterward, the optimized model was evaluated by other six events of floods (model validation). According to the obtained results, the runoff generation potential has been increased in the Talar watershed due to deforestation during the last forty years. Land use changes cause an increase in runoff volume and flood peak discharge.

Abstract:

Anthropogenic activities and climate change affect the type, structure and function of ecosystems, resulting in important changes in vegetation net primary productivity (NPP). Therefore, in this study we used the vegetation photosynthesis model (VPM) to reveal the spatiotemporal variations in NPP in Xinjiang from 2000 to 2019. The impacts of climate change and anthropogenic activities on NPP changes were quantified and separated by the residual analysis-control variables (RES-CON) method. The results showed that the average NPP in Xinjiang increased by 17.77% from 2000 to 2019. Anthropogenic activities and climate change generally had a positive impact on NPP from 2000 to 2019. The most important anthropogenic activity was land use and land cover (LULC) transformation from grass to arable land, which significantly increased vegetation productivity. Regarding climate change, precipitation has played a significant role in promoting the productivity of vegetation. Overall, the average contribution of climate change (temperature and precipitation) to NPP variation (21.44%) is much greater than the contribution of anthropogenic activities (3.46%), but in areas where anthropogenic activities occur, the average contribution of anthropogenic activities to NPP variation (75.01%) is much greater than the average contribution of climate change (15.53%). Where there are no anthropogenic activities, the average contribution of climate change to NPP variation is 21.72%. In summary, anthropogenic activities are the main driver of NPP variation in areas where anthropogenic activities occur, while the total area in Xinjiang where climate change is the most important driver is larger than the total area where anthropogenic activities are the dominant driver.

Abstract:

Climate change and anthropogenic activities are the two main driving elements influencing changes in streamflow. Previous studies mainly focused on the impacts of climate change and anthropogenic activities on annual mean streamflow (AMS), ignoring annual maximum streamflow (Amax) and annual minimum streamflow (Amin). On the other hand, most previous studies attributed the impacts of climate change and anthropogenic activities synoptically. However, the separate influence mechanism among climatic variables, such as precipitation, temperature, sunshine duration change, direct human activities, and land use cover change, needs further analysis. We used the Water and Energy transfer Processes in Large River basin (WEP–L) model to quantify the impacts of climatic variables (precipitation, temperature, and sunshine duration) and anthropogenic activities (land use cover change (LUCC) and direct human activities (DHAs)) on streamflow in the Caojiang River Basin (CRB) with a tropical climate. The results indicate that anthropogenic activities play a major role in streamflow indictor variation. Of the investigated factors related to climate change, precipitation showed the greatest impact on streamflow variation. Notably, DHA contributed the most to the variation of the three streamflow indictors, followed by precipitation, temperature, and sunshine duration, while LUCC had a much lower impact on streamflow variation. This study investigated the response of different streamflow indicators (AMS, Amax, and Amin) to climate change and anthropogenic activities, and it is of value to watershed resource planning and management.

Abstract:

ABSTRACT Anthropogenic danger is a danger that arises as a result of human actions or mistakes. Anthropogenic hazards can affect humans as well as wider ecosystems and various landforms. The influence of human activities on river ecosystems has encouraged the development of the concept of bioindicators to determine the health status of aquatic ecosystems. Percut river water quality is influenced by human activities that utilize the land around the river. The activities carried out by the community are for irrigation sources, pond irrigation, sand excavation and daily needs. Assessment of watershed vulnerability to anthropogenic activities using community perception approach. It is used because people's perceptions can directly build awareness and alertness in the face of danger and vulnerability. This study aims to determine the perception of society in anthropogenic activities in the upstream Percut watershed area and determine the relationship between the perception of the upstream Percut watershed to the behavior of anthropogenic activities that affect the vulnerability of watershed. This study uses survey methods. Data collection was done by: (a) Observation (observation), (b) structured and free interviews (questionnaires), and (c) secondary Data that support the research and the data were analyzed using Spearman rank correlation test. The results showed that the level of public perception in anthropogenic activities that affect the vulnerability of watershed is included in the category of moderate. Upstream communities assume that if the river is damaged, it will cause damage to the downstream, which will then affect the needs of the community directly. The perception and behavior of upstream peoples towards anthropogenic activities falls into the category of moderate. That means that there is no relationship between perception and behavior in the upstream Percut watershed quality. Keywords : Upstream Percut Watershed, Perception, Behavior, Anthropogenic

Abstract:

Anthropogenic activities often compromise the water quality of natural water systems, rendering it unfit for domestic and agricultural use. This paper evaluates the effects of anthropogenic activities on the water quality of Ngong River in Nairobi County, Kenya. It aimed to assess the river’s physico-chemical parameters, identify major anthropogenic activities that act as pollutant sources and establish the relationship between the anthropogenic activities and water quality along the Ngong River. Twelve water samples were systematically collected in each of the twelve study sites in April and August 2021 and analyzed in the laboratory for various water quality parameters. The accumulation factor (AF) indicated that E. coli, total coliforms, BOD and COD were found to significantly build up downstream of Ngong River. The ANOVA test results showed that all the physicochemical parameters studied (BOD, E. coli, pH, total suspended solids, total coliforms, turbidity, conductivity, nitrates, oil and grease and TDS), except COD, were not significantly different (p ≤ 0.05) for the different sites. Measured heavy metals, such as lead (Pb) levels at different sampled points, were all found to be below the detectable limit (0.001 ppm) for both seasons. Cadmium (Cd) was detectable during the dry season with the highest levels (0.113 ppm) being recorded at Ngong Forest Boundary. The findings of this study revealed that anthropogenic activities, such as raw sewage disposal, industrial activities, solid waste dumping and small-scale agriculture, had adverse effects on Ngong River’s water quality. The study recommends a need to closely monitor anthropogenic activities along Ngong River to reduce their probable pollution of the water in the River basin. This will ensure the sustainability of the water resources.

Abstract:

The aim of this study is to evaluate the existing available methods that can potentially be applied to anthropogenic spatial entities to access their environmental sustainability. The paper offers an overview of existing sustainability assessment methods, discusses their adequacy, and evaluates their efficiency to assess the environmental sustainability of anthropogenic spatial entities. From a list of sixty-one (61) sustainability assessment methods for spatial entities with anthropogenic activities that had been identified and examined, thirteen (13) methods were selected to be assessed based on specific exclusion criteria set. The thirteen methods were further classified into four categories, namely, (1) Indicators/Indices, (2) Resource Availability Assessment, (3) Material and Energy Flow Analysis, and (4) Life-Cycle Assessment, and then these methods were evaluated using specific evaluation criteria. The “Resource Availability Assessment” category, and particularly the “Ecological Footprint” method, was indicated as the most appropriate method to assess the environmental sustainability of anthropogenic spatial entities.

Abstract:

Water is a fundamental requirement for all living beings and it is considered as the most diverse solvent. It has a unique polarity and a distinctive set of properties due to hydrogen bonding. Water, being a universal solvent, can easily be polluted by absorption, adsorption and suspension of a lot of materials into it. Major sources of water contamination include the disposal of untreated garbage, milling, industrialization, and urbanization. Water is easily polluted by substantial metals including Lead (Pb), Arsenic (As), Copper (Cu), and Chromium (Cr). Water contamination can lead to serious illnesses and sometimes it is so hazardous that it can cause the death of a living organism.

Abstract:

This study evaluated the incidence of predators and anthropogenic activities affecting beekeeping in Nigeria. Questionnaires were administered in Oyo, Ogun and Osun States in the Forest Vegetation and Kaduna, Niger and Kano States in the Savanah vegetation zones of Nigeria. Data obtained were analyzed with parametric statistical tool of mean. The result showed that the largest populations of beekeepers were Bachelor Degree and National Certificate in Education NCE holders (25.0% each), MSc (8%), National Diploma ND (8%) and Postgraduate Diploma PGD (9%). Assessment of human activities that were harmful to beekeeping identified by respondents in the forest vegetation zones revealed indiscriminate use of pesticide (16.67%), theft (33.33%) and herdsmen activity (cattle rearing) (31.82%) while savannah vegetation zones had the following record, indiscriminate use of pesticide (25.00%), theft (35.33%) and herdsmen activity (35.71%). Avoidance of scattering honeybee (Apis mellifera L.) combs around the apiary was found as the most effective method in preventing spread of insect pests. Other methods include: hive sanitation, hive positioning, handpicking of insects, the use of spent engine oil, regular weeding, fencing of apiary and use of bee pen. The hives painted with green coloured paint was reported by respondent to control wasp, spider, termites and lesser wax moth. Beekeepers reported weeding as the most effective method used in controlling predators as it was noted that apiaries regularly weeded controlled the following predators with their respective incidence level: rat (8.33%), snake (12.50%), toad (29.7%), frog (20.83%) and ghecko (37.50%) while the most significant was lizard incidence which was 54.17%. Report from respondents on traditional methods to detect apiary problems categorized into predator and human activities include: decreasing size of colony, majority of bees staying outside the hive, sighting of pests in the apiary and abscondment of bees while human interference was noticed with dead bees found in and outside the hive, inactive bees, trace of burnt grasses and shrubs in the apiary and felled hives from stands.

Abstract:

Man has contributed to land cover alteration since time-immemorial through clearing of land for residential, agriculture, recreational and industrial purposes. The emergence of adapting wild plants and animals for human use as well as industrialisation have also contributed to the alteration of land cover. Over the years, anthropogenic activities have had great impact on the Weija catchment. This study seeks to map the catchment and determine the impact of anthropogenic activities using Remote Sensing techniques. Observations and measurements were made on the field as well as classification of land cover using Landsat images of years 1991, 2003 and 2017. Results showed an increase in built-up areas by 18% from 1991 to 2017. Other classes such as shrubs increased due to decrease in dense vegetation. This study confirms the use of Remote Sensing as a valuable tool for detecting change in land cover and determining the impact of anthropogenic activities in the Weija Catchment.

Abstract:

Aquatic ecosystems respond differently to diverse anthropogenic activities in their watersheds. Phytoplankton is sensitive to their environment and is used to monitor anthropogenic impacts. A study was carried out in a South-eastern Nigerian River between December 2017 and November 2018 in 6 stations; to assess the phytoplankton community, water quality, and anthropogenic impacts. Sand mining was a major activity in the river among others. The phytoplankton was sampled with the filtration method while water was collected and analyzed using standard methods. A total of 36 phytoplankton species were recorded with Chlorophyceae being the most abundant group. The most abundant species - Melosira granulata is a pollution indicator. The water quality and phytoplankton structure showed that the water was tending towards eutrophication. This is attributed to the observed anthropogenic activities and cumulative impacts of all the activities in the watershed. The impact of sand mining activities was observed more in the downstream stations (4 – 6) while perturbation from swimming children and related activities was observed in station 1. The community structure reflected the impacts of the activities while CCA showed the major water quality parameters that influenced the phytoplankton community structure.

Abstract:

This study aims to assess the anthropogenic activities of illegal mining on the environment and socio-economic dynamics at the location of gold mining without a permit in Madong Raya Village, Tanah Pinoh District, Melawi Regency. The research approach is qualitative with the aim of producing a descriptive analysis related to the data collected based on the construction of existing theories and literature. Field findings reveal that anthropogenic activities are still carried out by local communities in the defense of illegal mining and have an impact on environmental degradation and meet daily needs in financing families and the strength of interaction between residents in utilizing natural resources. Research data analysis was carried out in a descriptive way, namely the impact of illegal mining and social impacts society from anthropogenic activities causing prolonged degradation. Anthropogenic activities cause the decline in environmental quality and local people's livelihoods in meeting daily needs as well as developing community capacity and empowerment in a participatory, equitable, and environmentally friendly manner so as to create social and economic resilience as well as resilience to the effects of external changes by not carrying out mining activities. gold is illegal considering that there are casualties due to the mining

Abstract:

Models based on multifactorial interactions are needed to deal with the dynamics taking place in the eutrophication processes of coastal lagoons. However, as the number of indirect drivers stemming from anthropogenic factors increases, temporal disorders between anthropogenic activities may increase, thus hindering the understanding of their dynamics. We have built multifactorial pathways to deal with the dynamics associated with the cultural eutrophication process of a coastal lagoon. The pathways guided the identification of potential temporal disorder patterns between anthropogenic activities, which may exert influence on the disturbances associated with eutrophication process. The identification of temporal disorder patterns derived from anthropogenic activities belonging to different pathways resulted in a valuable form of support for analyzing and evaluating relationships between public policies, technological skills and environmental culture programs. All of which exert influence on the eutrophication process, which in turn cause changes on the trophic state and on the landscape of the coastal lagoon. Pathways composed of multifactorial interactions that take into account spatial and temporal aspects, contribute to improving the understanding of the inherent dynamics of the eutrophication process of coastal lagoons. Temporal disorders between anthropogenic activities may be seen to emerge, thus exerting changes on the trophic state and spatial damage on the landscapes of coastal lagoons.

Abstract:

The Sellafield nuclear fuel reprocessing plant on the northwest coast of England is the largest source of anthropogenic radiocarbon to the UK coastal environment. In a mid-1990s study of 14C distribution around the UK coast, the pattern of dilution with increasing distance from Sellafield appeared to be perturbed by anomalously high 14C activities in marine biota in the coastal environment of northeast England. This present study was undertaken during 1998 and 1999 to determine whether this 14C enhancement was due to Sellafield or the nuclear power plants on the east coast. Seawater, seaweed (Fucus sp.), and mussel (Mytilus edulis) samples that were collected from the vicinity of the Torness and Hartlepool advanced gas-cooled reactor (AGR) nuclear power stations were all enhanced above the contemporary regional background activity derived from natural production and atmospheric nuclear weapons testing. We used previously published dilution factors and transfer times for 99Tc between Sellafield and various points on the UK coast to determine likely Sellafield-derived 14C contributions to the activities at the nuclear power plant sites. The results suggest that the activities observed at Torness, which are only marginally enhanced above the natural background activity, are possibly due to discharges from Sellafield; however, the significant 14C enhancements at Hartlepool are not Sellafield-derived. Furthermore, since both reactors have the same fundamental design, the low activities at the Torness AGR imply that the activities at Hartlepool are not from the AGR, suggesting that there is an input of 14C to the marine environment in the vicinity of Hartlepool which is probably non-nuclear-power related. However, there is no other authorized site in the area that could account for the observed 14C enrichments; therefore, further research is required to ascertain the source of this 14C.

Abstract:

As human populations have increased, our impact can now be felt even in the deepest remnants of wilderness (Vitousek et al. 1997). The resource demands of the ever-increasing human enterprise are creating substantial amplification of man-made pollution, including noise production. The dominant sources of anthropogenic noise are transportation networks, development (including energy, urban and industrial) and recreational activities. These activities are increasing faster than population growth. Between 1970 and 2007 the US population increased by approximately one third whereas (http://www.census.gov/compendia/statabO traffic on US roads nearly tripled, to almost 5 trillion vehicle kilometers per year, (http://www.thwa.dot.gov /ohim.tutw/tvpage.cfm.) Similar trends in shipping noise have also been observed in marine ecosystems, as discussed in reviews of noise impacts on marine animals (e.g., Nowacek et al. 2007).

Abstract:

Abstract Soil profiles of the city centre of Debrecen were investigated in order to examine their properties and investigate the vertical distribution of heavy metals as a measure the anthropogenic activity. During the laboratory work the basic soil features were identified (texture, artefact content, pH, CaCO3, and amounts of organic matter). Furthermore, contents of Pb, Zn, Cu and Co in the soils were measured. Most of the metals showed a strong positive correlation with the humus content and the silt fraction. The soils of the city centre are exposed to a significant anthropogenic effect, therefore the original soil morphologies are usually difficult to identify. The soil profiles are greatly disturbed, which is traceable in the vertical distribution of certain soil features and metal contents.

Abstract:

The rapid growth of metropolitan regions is closely associated with high nitrogen (N) flows, which is known as the most important reason for widespread water pollution. It is, therefore, crucial to explore the spatiotemporal patterns of N budgets under intensive human activity. In this study, we estimated the long-term (2000–2015) N budgets by integrating the net anthropogenic nitrogen input (NANI) and the export coefficient model (ECM) in the Yangtze River Delta Urban Agglomeration (YRDUA), a typical metropolitan area with strong human disturbances. The results revealed that the NANI decreased by 10% from 2000 to 2015, while N exports showed a 6% increase. Hotspots for N budgets were found in the northeastern areas, where cropland and construction land were dominant. The linear regression showed a close relationship between the NANI and N export, and about 18% of the NANI was exported into the river system. By revealing the critical sources and drivers of N budgets over time, our work aimed to provide effective information for regional policy on nitrogen management. Future strategies, such as improving the fertilizer efficiency, optimizing the land use pattern, and controlling the population density, are necessary in order to address the environmental challenge concerns of excessive N.

Abstract:

Fine particulate matter (PM2.5) from different sources with different components have different health impact. In this research in Taiwan, composition and cytotoxicity of PM2.5 from long-range transport event (LRT), traffic activity, and outdoor cooking at night market were studied. The PM2.5 mass concentrations were 39.0 μg/m3 during LRT, 42.9 μg/m3 at traffic area, and 28.3 μg/m3 at the night market. Traffic area had highest concentrations of PCDD/Fs (46.9 fg I-TEQ/m3) when highest PAH concentrations of 3.57 BaPeq-ng/m3 were found at night market area. One quarter of PM2.5 mass at LRT and night market was constituted by water-soluble ion (26.02–28.93%). Road dust (represented by high concentration of Al and Ca) was the main contributor for metal element at traffic station whereas presence of natural salt (Na and Cl elements) was a marker of LRT and cooking activities. Cell viability reduced 9% after exposure to organic extracts of 0.316 μg of PM2.5 from LRT and night market samples. 150% elevation of ROS production was observed after exposure with organic compound of night market samples at the dose equivalent to 10.0 μg PM2.5. Organic extracts from night market induced positive genotoxicity in umu test (at a dose of 20.0 μg PM2.5).

Abstract:

Background: It has been claimed that the turndown of insect population due to strengthening agriculture may have led to a reduction in the number of farmland birds some autecological studies support this postulate. Insect abundance is significantly associated with bird density measures large scale invertebrate sampling was done using suction traps and results showed that with time as food quality and quantity changes there is a decline in farmland birds. Method: The study was conducted for a period of one year, point count method was adopted to record these parameters. Relevant field guides were used to identify observed bird and insect species. Several avian species were seen preying on several insects. Such instances were listed and we also concluded about the insectivorous nature of several avian species based on sightings. Results: In all the four sites collectively, order Lepidoptera of Insect fauna is dominant in all the four study sites. Several anthropogenic stresses were reported in the present study, these activities should be checked regularly and must be prohibited. During three time slots, the activity of birds was recorded and family wise bird activity were observed. Results showed that there were few species common in all the three-time slots and some disparity was recorded in their availability in the morning, noon, and evening respectively.

Abstract:

River Chanchaga is the major source of drinking water in Minna, Nigeria. This river has been a medium to an increasing pollution loads from contaminated runoff from different land uses degrading aquatic ecosystem and water quality in the river.This paper investigates the threat of anthropogenic influence on river environment and aquatic ecosystem distortion of River Chanchaga, Minna, Nigeria. Field work which include interview and observation methods were used to collect data on effect of anthropogenic and eutrophication along the study area. A total of Two Hundred and Fifty (250) people accounting for 0.5% of the total population were interviewed, making it eight per each community in thirty settlements along the study area. Physical observation of deforestation around sample sites spatially distributed along River Chanchaga depicted in Figure 2 was carried out to study mining activities, farming practice, crop types, and fallow duration to generate the mean and percentages of different anthropogenic activities along the study area. The findings revealed that deforestation is links to high demand for fire wood, lumbering, irrigation farming bank-side mining for sand and gold as depicted in Plat 1 and 2. Eutrophication at the upper course of river is links to high inflow of agricultural wastes and seasonal nature of the river from site A to C evident from Table 4 and constant flow from site C to K as a result of released water from Tagwai Dam that keeps (site C, the confluence of River Chanchaga and River Numui) middle and lower courses of River Chanchaga with sustainable moving water. The result further indicated that continue increase of pollution has a direct relationship to an increasing level of human activities like deforestation, mining activities and agricultural practices along the study area. The result also shows that there is decline in fallow duration as indicated in Table 1 and increase environmental related issues such as soil erosion, water floor (depth) reduction and distortion of river morphology of the study area. It is therefore recommended that the identified anthropogenic activities that lead to pollution and eutrophication such as river-side deforestation, irrigation farming, mining and other related environmental problems should be regulated and discourages to avoid further increase of pollution and distortion of river environment of the study area.

Abstract:

Abstract. Thermal emissions – or anthropogenic heat fluxes (QF) – from human activities impact urban climates at a local and larger scale. DASH considers both urban form and function in simulating QF through the use of an agent-based structure that includes behavioural characteristics of urban residents. This allows human activities to drive the calculation of QF, incorporating dynamic responses to environmental conditions. The spatial resolution of simulations depends on data availability. DASH has simple transport and building energy models to allow simulation of dynamic vehicle use, occupancy and heating–cooling demand, and release of energy to the outdoor environment through the building fabric. Building stock variations are captured using archetypes. Evaluation of DASH in Greater London for periods in 2015 uses a top-down inventory model (GQF) and national energy consumption statistics. DASH reproduces the expected spatial and temporal patterns of QF, but the annual average is smaller than published energy data. Overall, the model generally performs well, including for domestic appliance energy use. DASH could be coupled to an urban land surface model and/or used offline for developing coefficients for simpler/faster models.
