Wars, inter-community conflicts and the nebulous Boko Haram sect are the causes of massive displacement of populations from neighboring countries to Chad and Kaya. The arrival of Nigerian and Nigerian refugees, returnees and internally displaced Chadians has increased the population and the need for energy, especially firewood and charcoal. Moreover, to meet their food and financial needs, these migrants are forced to destroy the plant resources of the region and of Kaya in order to survive. This is damaging the natural environment and the economy of the Lac and Kaya region. Thus, 25 refugees, returnees and displaced persons were studied and empirical data collected in order to determine their responsibility in the degradation of vegetation in Kaya. Then, 3 people in charge of the environment in Bagassola were interviewed to gather their opinions on the role played by refugees, returnees and IDPs in Kaya in the environmental degradation in this area. Five interviews were held with NGOs in Bagassola to find out the underlying reasons that lead refugees, returnees and IDPs to destroy nature.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130615582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has affected health, fishing, subsistence farming, and the economy of residents of this region. The objectives of this study were to model rainfall with respect to the percentage land cover type and forecast the percentage land cover type in 2040 for the river Niger-Delta. The objectives were met by reviewing literature related to this study, data acquisition, and modeling. The data was accessed from Google Earth Engine and the World Bank climate websites. ArcGIS, Microsoft Excel and SPSS software were used to analyze the data. Land cover and rainfall data was modeled over ranges of time and data pairs from each variable for similar years were extracted and used to model the variation of rainfall versus land cover types. The land cover and rainfall data analyses are presented in the analysis section of this paper. The percentages of land cover in the study area under water and built-in were found to have increased while that under mangrove and vegetation were found to increase respectively between 1990 and 2040. Communities residing in the study region are highly vulnerable to the impacts of floods and water pollution by industries for half of each year. This study suggested several policies for the Niger-Delta well-being and protection of the region’s residents with respect to floods and related issues.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"73 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131515883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, the way land is used affects the generation and character of traffic on the streets and roads corridors. This paper investigated the road traffic noise differentials in the land uses of Jos, Nigeria. Twenty-five (25) road corridors, five (5) in each of the selected land use were purposively chosen to constitute the sample frame for the study. Road traffic noise data were collected at the sampled locations along the selected road corridors using Graiger TL-200 digital Sound Level Meter at 1.5 accuracy level and measured range of 30-130 dB. The road traffic noise data were collected three times a day during peak hour periods, 7:00 - 9:00 am, 12:00 noon - 2:00 pm, and 4:00 - 6 pm from Monday to Saturday. Noise data were measured for 15 minutes at an interval of 6 seconds in each location for six days, making a total of 18 records per location. The RTN data was analyzed using descriptive statistics and regression analyses. The findings of this study revealed that, there was a significant mean difference in RTN levels in the land uses of Jos. This paper therefore, recommends land use dispersal, markets and commodity specification within Jos as a strategy for reducing road traffic noise.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125290583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although municipal authorities in the city of Dhaka recognize the importance of adequate solid waste collection as well as resource recovery and recycling, it is beyond their resources to effectively deal with the growing volume of solid waste. As a result, solid waste is dumped indiscriminately on streets and open drains causing serious health risks and degradation of the living environment for millions of urban people. In the last decade, the importance of community involvement in solid waste management and the use of adaptive technologies to improve solid waste management systems have been recognized but waste is a material that no longer serves a purpose and is therefore discarded. All wastes are particularly hazardous if not disposed of carefully, they will have an impact on the environment, be it unsightly litter on urban streets or polluted air, soil, or water. Solid waste management practices are not very satisfactory in the recent world and adequate policies and awareness about various aspects of waste management are needed to help reduce waste generation and improve waste management processes. This research paper has worked on Dhaka city, the capital city of Bangladesh and it has tried to find out the current status of solid waste through 3R strategy including energy analysis. Moreover, this paper has discussed the potential of power generation from solid waste.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130791316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate adaptation results in noticeably higher yields from food crops. Climate change events have had a detrimental impact on farmers in Ghana, especially in the Upper East region. This includes producers of legumes in the Bongo District, which is a part of the fragile savanna semi-arid zone. The growing food insecurity and failure of legume crops point to serious losses in climate change adaptation methods. Farmer’s adaptation strategies have fallen short over time, necessitating a revision of programs to assist growers of legumes in the Bongo District. The obstacles connected with indigenous and contemporary adaptation techniques to climate change are also examined in this study, along with local and contemporary stakeholders’ involvement in adaptation efforts. The primary data was gathered through the use of focus group discussions and interviews. In three communities, 70 farmers who grow legumes were sampled using a simple random sampling technique to select the respondents. The study concludes that farming and mixed cropping are important indigenous adaptation techniques, whereas forecasting and greater variety are important modern adaptation strategies. The MoFA and the Bongo District Assembly are the two important entities in executing adaptation plans, while local farmers were highlighted as key stakeholders. Additionally, it was determined that weak extension services and a lack of integration of indigenous adaptations into contemporary practices could pose serious obstacles to developing climate change adaptation strategies. The study recommends integrating local and contemporary adaptation strategies to combat climate change.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123138546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study employed the quantitative research method to achieve its objective. The datasets consisted of historical records of monthly observational data of temperature and rainfall collected over 22 years (2000-2021), and yearly records of cassava, yam, and maize yield data collected over 22 years (2000 to 2021). Trend analysis was conducted to examine the trend in the climate variables (temperature and rainfall) and the yield of the selected food crops (cassava, yam, and maize) over the study period. A marginal variation in annual rainfall and temperature was observed over the study period. The municipality experienced slightly decreasing trends in annual rainfall and increasing trends in annual temperatures. Significant variations and increasing trends in the yields of the respective food crops were observed. Using standard regression methods, the result shows that maximum and minimum temperatures are associated with increased yields for yam, maize and cassava, but annual rainfall is not significantly associated with the variations in the yields of the selected food crops. The study, therefore, suggests that further research be undertaken to investigate how other environmental and non-climatic factors influence crop production in the Wenchi municipality.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121450066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several aspects of an individual’s prosperity, like communal, financial, and ecological increment, were impacted directly or circuitously by climate change. Moreover, the Bangladeshi people’s life is extremely affected by heavy rainfall because of its geographical structure, especially in the South-West region. Hence, this paper has experimented with the monthly average monsoon data of average temperature, wind speed, relative humidity, mean sea-level pressure, cloud cover, and rainfall from 1981-2018 and predicted the precipitation of 9 meteorological stations from 2019-2028 of the South-West part of Bangladesh. The monthly average monsoon rainfall strongly correlated with relative humidity, mean sea-level pressure, and cloud cover among all the mentioned weather variables. An artificial neural network (ANN) model was formulated with a gradient descent algorithm to predict the rainfall. R2 value was also measured to see the accuracy of the model. Thereafter, the nine stations of the given region have the following order of average monsoon rainfall:Khepupara(15.22mm)>Potuakhali(14.01mm)>Bhola(11.36mm)>Barishal(10.68mm)>Mongla(10.25mm)>Khulna(9.33mm)>Satkhira(9.00mm)>Faridpur(8.67mm)>Jashore(8.64mm). The predicted and real rainfall patterns showed the same escalating or plummeting trends for each station, which justified the ANN model for predicting the monthly average monsoon rainfall of the South-West region in Bangladesh. Such a rainfall prediction can assist people of this region to be more equipped for adverse heavy rain, saving lives and decreasing infrastructure loss during the monsoon season.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"65 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126289210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sands (SP-SM) are mainly uniformly graded and composed of more than 72% to 98 % sand. This research has been carried out to assess the liquefaction potentiality index vales, susceptibility using SPT and risks associated with the Ukhiya hills at different earthquake magnitudes. During earthquake at Magnitudes 5 or greater, Ukhiya hill soils are susceptible to liquefy up to a depth of 12 m.. From the Liquefaction Potentiality Index (LPI) values, risk and sensitivity analysis, it is established that the Ukhiya hills are medium to highly susceptible to liquefy at higher magnitudes (M= 5 or greater). It is also established that north western part of the camp hills are high to very high risk prone areas. Based on Liquefaction Potentiality Index (LPI) values, four seismic risk zones are identified in and around the Rohingya camp area. Some geo-engineering recommendations are also made to reduce this seismic hazard for sustainable community living in the camp area.","PeriodicalId":199881,"journal":{"name":"American Journal of Environment and Climate","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134280581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
