Shortage of vitamin A is a public health issue in Ethiopia. Investigations demonstrated that especially pre-school students are so influenced by this issue. There are numerous reasons, which cause vitamin A shortage while the insufficient dietary information is the main reason in developed countries. This study's aim is assessing dietary vitamin A utilization by pre-school students aged group 2 to 5 years in Sodo Zuria community, South Ethiopia. A cross-sectional study has been performed utilizing 2 step group sample method has been utilized for selecting the usual samplings of 576 pre-school children from 3 rural kebeles of the investigation site. An adjusted 7-day HKI food frequency questionnaire and 24 hours FANTA food variety score have been utilized for estimating the dietary in taking of Vitamin A. This study's outcome determines that 99.5 percent of pre-school children had used Vitamin A rich foods from animal sources ≤ four times and 98 percent of pre-school children have been using animal and plant resources of Vitamin A rich foods ≤ six times every week. The average frequency of animal utilization resources of Vitamin A has been 1.42 times and the average utilization of whole animal plus plant resources of Vitamin A has been 3.01 times for the last one week. The results demonstrated that the utilization frequency of Vitamin A rich foods have been lower than the threshold amount of HKI and PAHO/WHO recommendations. By considering the FAO standards dietary utilization of Vitamin A by a lot of pre-school children has been insufficient and they have been in danger of VAD issue. Therefore mother or caregivers of the kids must enable their pre-school children for eating Vitamin-A rich foods per day minimum a food items which are animal foods, yellow, orange fruits, and green vegetables.

Forests play an important role in removing carbon from the atmosphere and help slow climate change by sequestering carbon dioxide and store as carbon while fire, disease, vegetation conversion such as land use change releases carbon dioxide into the atmosphere. In this study, InVEST model was adopted using Geographic Information System (GIS) to estimate Carbon stored, sequestrated and design a REDD policy for Nigeria between 1984 and 2035. Total carbon sequestrated decrease from 4,856,430,592Mgha-1yr-1 in 1984 to 2,018,537,728Mgha-1yr-1 in 2003 and then, to 826,727.99Mgha-1yr-1 in 2035. Also, total carbon stored decrease by 15,594,440,704Mgha-1yr-1 in 1984 to 11,968,108,544 Mgha-1yr-1 in 2003 and then, to 11,115,581,440Mgha-1yr-1 in 2035. While, total carbon emitted increased from 887,287,616Mgha-1yr-1 in 1984 to 1,599,485,568Mgha-1yr-1 in 2003 and then, to 1,766,186,368Mgha-1yr-1 in 2035. Based on these, a REDD policy initiatives was adopted to improve carbon storage by sequestrating 4,619.97Mgha-1yr-1 and 912.85 Mg ha-1yr-1 in 2003 and 2035 while storing 4,619.97Mgha-1yr-1 and 4,679.19Mgha-1yr-1. To achieve this, a REDD policy scenario was created under the confidence area (at 90%) to increase carbon sequestration by 38% for2003 and 21% for 2035 which in-turn improves the economic benefit gained by $699,241.75 in 2035 compared to $406,799.63 in 2003. These plans acknowledged the importance of forests in addressing climate change and potential boon REDD represents under the Business-As-Usual (BAU) scenario.

The work determined the physicochemical properties and quality of groundwater samples from Industrial cluster areas of Anambra state, Nigeria using Quality Index method. The samples were collected monthly in rainy season (May–July, 2017) and dry season (November, 2017 to January, 2018). The ranges of the physicochemical parameters in both seasons were temperature (27.0–30.4oC), pH (5.5 – 6.5), electrical conductivity (22.5–178 µS/cm), calcium (1.00–17.67 mg/L), magnesium (0.00–13.33mg/L),total hardness (1.00–27.00 mg/L),chlorides (0.83–16.67mg/L), sulphate (0.33–4.00 mg/L), total alkalinity (0.75–16.67 mg/L), total dissolved solids (13.50–106.67 mg/L), total suspended solids (1.03–9.67 mg/L), total solids (16.00–116.33 mg/L), turbidity (0.00–3.04 NTU), dissolved oxygen (5.67–9.07mg/L), biochemical oxygen demand (0.10–1.27 mg/L) and chemical oxygen demand (5.67–18.33 mg/L). The values were compared with the standard values recommended by World Health Organization (WHO 2017) and Nigerian Standard for Drinking Water Quality (NSDWQ 2007). Statistical analysis (ANOVA) was performed which showed significance variations between the parametric values of the borehole water samples. Levene’s t-test indicated significance variations between the rainy season and dry season parametric means. The water quality index (WQI) results in both seasons showed that the water quality status of the samples collected from Uruagu, Nnewichi, Okpoko and Awada were excellent while those collected from Otolo, Umudim, Fegge and Woliwo were good.

Discussing climate change can only be achieved if the public understand the severity and the gravity of climate change and modify their behavior in directions that decrease hazardous discharge into the atmosphere and advocate adjustment, whereas the complexity, ambiguity and the vast scope of the issue which encompasses both the earth and the space have caused the obstacles for the understanding of the people of the society, which present a dire need for the crucial Climate Change Communication (CCC). Public’s search of knowledge and media application mode is a grave threat which needs to be annihilated for the convincing CCC. The current study has carried out a primary assessment of public’s search for knowledge and the application of media based on a national review which was conducted haphazardly of public outlook on climate change in mainland China. Results from the survey exhibit that the Chinese participants use TV as their most significant information seeking route, take into account the science organizations as the most reliable information route, and show little interest in the environmental related news content. Numerical associations between the parameters involved in communication that were mentioned above and consciousness on the subject of the climate change have also been examined. A few suggestions for CCC guidelines are brought forth according to the results of this study.

The efficiency of the Nitrogen utilization and root nodules' life cycle in alfalfa after various mineral fertilizing and cultivation of soil methods have been investigated. The field test has been performed in the Forage Crops Institute, Pleven, Bulgaria on leached chernozem subsoil kinds and with no irrigation. The next cures have experimented: 1) for fertilization as below: N0P0K0 (controlling); N60P100K80 (an admitted technology); N23P100K35 (nitrogen has been used 1/2 in the first year of grow and 1/2 in the third year); N23P100K35 (nitrogen has been provided pre-sowing); N35P80K50, and Amophose – 250 kg/ha, estimated at fertilization rate N27P120K0; ii) for soil cultivation as below: soil losing 10-12 cm, plow at depth 12 to 15 cm, 22 to 24 cm (an admitted technologies), 18 to 22 cm and 30 to 35 cm. It has been seen that the cultivation of soil and mineral fertilizing had an impact on nitrogen utilization efficiency and the root nodules' life cycle in Alfalfa. Nitrogen utilization efficiency has been discovered for being maximum at N23P100K35 and plow at the depth of 22 to 24 cm. The root nodules' life cycle has been the longest at N35P80K50 and plows at the depth of 18 to 22 cm. The more useful root mass for nodule number ratio has been seen at N23P100K35 and plow at the depth of 22 to 24 cm.

In this study, the runoff curve number map for Navrud watershed in north of Iran was determined based on the soil hydrological group, land-use and land-cover using remote sensing and geographical information system. For this objective, land-cover and Land-use situation maps were prepared using NDVI index and Landsat satellite data, respectively. Runoff curve number maps were determined using the overlay prepared maps in GIS and SCS table. For evaluating the accuracy of estimated curve numbers, runoff maximum discharge was calculated using HEC-HMS model and compared to the observed values. Furthermore, the climate change trend and probabilistic distribution functions were considered to predict the flood risk. The effects of climate change were defined by atmospheric general circulation models for A1B, A2 and B1 scenarios. Error analysis between calculated and observed discharge showed that watershed curve number was determined with acceptable accuracy.

Dinder River is largest tributary of the Blue Nile. It is seasonal river that flows from June to November and reaches its high peak in September. Frequently, the water level exceeds the normal height causing over bank flow and consequently floods. The floods generally ring about losses properties and crops close to river banks. This study is attempts to figure out the river flow behavior and find out the aerial extent of inundated lands in four flooding seasons. The investigated area is located in Sennar State, SE Sudan. Discharge data collected over the period from 2015 to 2018 and Digital Elevation Model (DEM) have been used to model the River flow regime, while land cover data was used to determine the affected LU/LC types in the area. HEC-RAS software was used to create 2D unsteady flow model in order to simulate Dinder River flooded area in four seasons. The largest flooded area extent in each season was used as input in GIS environment for further spatial analysis. Statistical computation for the affected area and consequent analysis revealed that: the affected urban area in 2018 was around 28.152km2, in 2017 was 29.205 km2, in 2016 was 16.531km2, and in 2015 was 10.422km2. Similar calculations were carried out for the other LU/LC types. According to the present study, the year 2017 witnessed the largest extent of flooding in the area.

Through rapid urbanizing and quick economically globalizing, the expressway, which is one of the significant highway networks parts, is formed at an incredible rate that obtained growingly intense ecologic environment concerns though contribution significantly for humans. Thus, promoting economically improvement and at the same time controlling the negative expressway effect is essential. It must be an endurable expressway landscape. In this study, the features and the encountered differences of an endurable expressway landscape are investigated. The eco-control system in the endurable expressway landscape has been formed containing the theory and technology control system, adopting ecology, designing, cybernetics, landscape, and related expressway thesis for all guide approaches to the controlling procedure. This can be a combination of engineering technology, processes, and warranty of an endurable expressway landscape. The controlling technology contains 3 layers such as master controlling from 2 sides of designing and key nodes, subsection controlling specifically for the expressway feature of inner and outer factors, and management controlling cross the all living procedure cycle of the expressway. The endurable expressway landscape's eco-control system could be executed on 3 scales such as macro designing controlling, meso-design controlling and micro-engineering and technical controlling.

Water ecosystem services are benefits obtained from natural processes held by terrestrial vegetation in relation to hydrologic systems. These benefits have implications for human wellbeing through the mitigation of flood risk, management of stormwater runoff, and removal of pollutants from water systems that ultimately supply drinking and irrigation water. Assessing national and regional stocks of these important ecosystem services is crucial for the sustainable development of the land and for conservation purposes. In this study, we applied three models from the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) tool to map the production of flash-flood risk mitigation, stormwater retention, and nitrogen retention. Our findings were consistent with impact assessments on local communities. Through the three ecosystem services mapped, we demonstrated the role of existing terrestrial vegetation in processing hydrologic systems in the Republic of Ecuador. The results from this modeling also provided insights into potential planning pathways for future management using the InVEST software.

Our current concern is that nitrogen and phosphorus amounts are rising rapidly, Otherwise, to limit the growth of algae and biomass, it exists in relatively low concentrations in unmodified natural waters. This investigation aims to attempt to measure the level of eutrophication in the Hosur LakesFor this research, we chose three lakes named Chandrakudi Lake, Doddan Lake and Kelavarapalli dam. For dissolved orthophosphate, chemical oxygen need, organic nitrogen, free ammonia, inorganic nitrogen whole phosphorus and soluble oxygen, etc. some exemplars were gathered and examined. The onsite research as transparence, facts on killing fish and deterioration of the lakes conditions, etc. was also accomplished. The eutrophication rate in the lakes was measured using the Wetzel's plan. The results showed that the rate of eutrophication was very high in all three lakes, i.e. more than enough to very rich in nutrients that cause excessive plant growth, which chokes out the animal life in the water.

Freshwater is discovered in thirty percent of the ground which lands located by several water sources and humans living there along by eighty percent of bio-diversity. The human population is growing and requiring freshwater. Now humans are relevant eighty percent of freshwater to underground water for farming and daily activities in urban areas. By considering the heavy utilization of underground water, the surface water sources are influenced, especially in the summer. Patna is the capital of Bihar state (India), and the urban zone is developing so quickly now loaded by about 2 million people restricted with Sone, Punpun, and Ganga by Gandak rivers. The ground is plain and there are a dozen ponds for recharging the underground water. In May, the Punpun River includes little water, Sone and Ganga contain lower than ten percent of water in October. People are utilizing underground water by mainly utilizing tube well of >200 feet depth that is go down thirty to fifty feet deeper every year according to slightly restore velocity. It is according to minimum rainwater production. Most of the rainwater runoff is in the Ganga River. Patna requires twelve billion liters of water for billions of rupees in May, and the temperature increases 5 to 7 Degree Celsius higher than the temperature of April generating an alarming condition in the community, especially for fishes, amphibians, birds, and even mammals. The condition becomes so difficult while air contamination, fluoride, and arsenic toxic generate death to organisms cause extinction. for meeting this threatening condition, each rainwater drop must be gathered by the pond's network. At least > ten percent of the land is needed for ponds for meeting the need for water of the increasing human and other organisms for saving green earth.

Nitrification procedures could have a significant position in the performing of Western Australia natural ecosystem. It is instantly concerned in plant nitrogen defeats via learn and denitrification. This process suppression with pastureland is incorrectly comprehended. The study has been accomplished on the deep sand at Mingenew in the Northern Agricultural Region,WA. Nitrification amount has been specified yearly, perennial pastureland and tagasaste grasses cultivated in site. Nitrification and prohibition amounts have been estimated according to measures of NH_4-N,NO_3-N insix months. In natural situations, the nitrification amounts of ammonium-N (NH_4-N) have been fast from 80 to 97 percent in the season. Nitrification amounts under yearly, perennial pastureland and tagasaste plants have been 35 to 80 percent, 58 to 58 percent, and 30 to 75 percent orderly. There is a highly negative correlation i.e., R^2= -0.84 between biomass and nitrification amount, and a highly positive correlation among biomass and prohibition amount i.e., 0.74. These outcomes present that pastureland types could have significant effects for nitrogen cycling at the constant growing and individual density.

This investigation has been carried out for evaluating the element's effect significance in ambient air and the environment distribution. The outdoor air measures were performed in winter for investigating probable sufficient particulate material PM exposure of various size aerosol RSPM and SPM. The element contamination measures were carried out at the Indian Institute of Technology campus in New Delhi regarded as a potential reference site for contamination investigation. The specimens have been accumulated outdoor on the third floor fifteen meters above the street for a twenty-one h period and the factors of Cr, Mn, Fe, Cu, Ni, Zn, and Pb have been calculated utilizing atomic adsorption spectroscopy analysis. The outcomes demonstrate that the RSPM and SPM fine mode or coarse mode ratio is 52.7 percent. The component concentration contribution in the site air contaminant is indicated fairly by the anthropogenic distribution in ambient air. The enrichment factors value for components Cr, Fe, Cu, Ni, Zn, and Pb probably derived from the anthropogenic emission resource, when the low enrichment element of Mn amount contributed to soil features distribution.

A dry spell is defined as the consecutive number of days with precipitation less than a specified threshold value of a standardised precipitation index (SPI). A cumulative effect of these dry spells amount to drought events and thereby negatively affect socio-economic activities in the communities. The current study aimed at determining the influence of El Niño-Southern Oscillation (ENSO) aided by Southern Oscillation Index (SOI) in order to make easy prediction given clear SOI cyclicity of anything from 3 to 7 years. The study used SPI to define dry spells and was also used a conceptual framework to quantify dry spells. A spectral analysis was also applied to SPI-1 time series datasets to determine return levels to provide government and all relevant authorities with behavioural characteristics of dry spells in the area for proactive mitigation strategies. Main results of this study ENSO having no direct influence over all the selected station’s precipitation. All the stations showed an average of 12 months or 1 year return level. This implies that after every 1 year, the study area is highly likely to experience dry spells which could lead to detrimental effects of the most important amenities of the study area. This phenomenon provides authorities with relevant information to plan proactively as dry spells may amount or graduate to drought events and thereby adversely affect water consuming activities in the area.

Geospatial data analytics is an essential tool in the toolbox of contemporary forest engineering and natural resource management. Beyond its application in estimating wood and fiber production, geospatial data analytics also proves indispensable in conservation planning. By leveraging a myriad of geospatial datasets, forest engineers and natural resource managers make well-informed decisions regarding forest restoration and carbon sequestration that foster environmental sustainability. However, one often-underestimated aspect of geospatial data analytics is its potential to help identify and address issues of distributive justice relating to forest resources and associated benefits. Thus, this article outlines a roadmap for forest engineers and natural resource managers to harness geospatial data effectively to simultaneously promote environmental sustainability and distributive justice – that is, the fair and equitable allocation of natural resources, nature’s benefits, and environmental burdens. The approach involves defining local concerns and priorities through community engagement to guide spatial data gathering, determining spatial and temporal scales of assessment, accessing and preprocessing data sources, developing prioritization indexes, performing relevant analytical tests, and creating opportunities for data return prior to decision making. Through this methodological approach, forest engineers and natural resource managers can harness the power of geospatial data to model and synthesize information, assess ecosystem services, evaluate community risks, and identify environmental hazards. In a world where data is abundant but its transformation into actionable insights is often lacking, this overview aims to illuminate the potential of geospatial data analytics as a tool that can simultaneously advance environmental sustainability and distributive justice.

Drought is a major environmental problem that affects agriculture, water resources, and communities around the world. In the Lesotho Highlands commercial dams, drought can have a significant impact on agricultural production, water supply, and local livelihoods. Understanding the patterns and severity of drought is crucial for effective water management and agricultural planning. This study aimed to analyse and understand the patterns of agricultural drought in the Lesotho Highlands commercial dams through the use of the Standardized Precipitation Index (SPI) and the theory of runs, as well as various drought parameters. The study used Average Dry Spell Duration, Drought Tendency, Longest Dry Spell Duration, Longest Multi-year Drought, Largest Single Year Drought, Standard Total Accumulative Dry Spell, and Number of Consecutive SPI-values, to provide a comprehensive analysis of the drought situation. The results revealed that the precipitation levels at the four dams were relatively similar, but with a potential increase in precipitation at Muela Dam. The SPI-3 and SPI-6 analyses showed a significant downward trend indicating an increase in dryness in the area. The drought parameters did not show significant differences between the stations/dams, indicating similar levels of drought across the dams. The study recommends regular monitoring of precipitation and drought conditions using the SPI and other water-balance drought indices, development of water conservation and management strategies, use of drought-resistant crops and water-efficient agriculture practices, and increased collaboration among stakeholders for sustainable water management and agricultural resilience.

Data were reduced by transcription and coding of the various data sources. The findings of the study show that there was no legislation directly talking to e-waste management in the country. E-waste was disposed of together with general waste at landfill sites. The importation of e-waste is not monitored since no legislation controls this activity. Telecommunication companies auction obsolete electronic gadgets to the public and other companies. The regulatory institutions did not consider e-waste a major problem in the country. There is no control over the importation of e-waste at ports of entry, resulting in non-compliance with the Basil and Bamako Conventions. E-waste was not regarded as a major problem in the country. This misconception results in a lack of control over the management of e-waste in the country resulting in environmental and Public Health problems.

During recent years, the shortage of surface water resources is a serious problem facing to the Chaharmahal and Bakhtiari province. Hence, the groundwater exploration should be limited for developing the new water resources such as artificial recharge. One of the main step of this process is locating suitable sites for constructing the artificial recharge structure. The objective of this study is determination of effective parameters on artificial recharge structure construction in Shahrekord plain to propose the best sites. The eight parameters affecting the artificial recharge structure construction are including permeability, hydraulic conductivity, precipitation, land slope, nitrate concentration, salinity, saturated and unsaturated thickness of aquifer. For this purpose, ArcGIS10.3 software for the analytic hierarchy processes (AHP) and Expert Choice 11 software for prioritize suggested areas were used. Weight permeability 0.28 was in the first preference, hydraulic conductivity 0.23 in the second preference, saturation thickness of aquifer 0.17 in the third preference. Permeability, hydraulic conductivity and saturation thickness of aquifer are considered as the main parameters with the weight of 0.28, 0.23 and 0.17, respectively. Moreover, the weights of precipitation, land slope, and unsaturated thickness were obtained o.11, 0.08, and 0.06, respectively. The results show that about 0.089 percent of the study area are suitable for artificial recharge structure construction.
