The review articles show the significance, challenges, and conservation strategies for wild and migratory bird habitats in South Asia which have diverse landscapes host crucial ecosystems, providing breeding grounds, stopovers, and wintering areas for countless bird species. Anthropogenic activities, climate change, pollution, and invasive species threaten these habitats, necessitating effective conservation measures. Habitat assessment, monitoring, restoration techniques, and adaptation strategies are explored. The impact of climate change on bird habitats is discussed, emphasizing the importance of habitat resilience and adaptive management. Community engagement and education are pivotal in conservation, with successful models involving local communities in decision-making processes. The article also addresses the status of illegal bird hunting in the Indian subcontinent, emphasizing the need for strengthened law enforcement and community involvement. Though birds are important element of the environment, however, they are cause to spread some disease in especially migratory birds. It’s have contribution to biodiversity, pest control, and pollination but can also cause economic losses in agriculture and pose risks to aviation. Managing coexistence between birds and human activities is required for successful conservation program. Interdisciplinary research, long-term monitoring, and quantitative assessments of habitat resilience is underscored. The article concludes with a future plan for wild and migratory bird management in Bangladesh, outlining measures such as habitat protection, community involvement, and international collaboration. \u0000Graphical Abstract \u0000 ","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"28 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139531458","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}

In Mount Kenya Wildlife Conservancy, water pans were constructed to provide water to animals during wet and dry seasons. The study aim was to establish patterns of water pans utilization by different mammal species in different seasons and times of the day. Study was conducted on the mammals visiting water pans in the dry season (June 2022) and wet season (October 2022) at two water pans in Mount Kenya Wildlife Conservancy. Mammal utilization of water pans was studied using observations and camera traps. Pearson correlation and t-test were used to analyze data. Impala had the highest water pan visitations (36.7%) followed by zebra (22.2%) while eland and reedbuck had the lowest (0.7%) visitations. Morning (0900hrs-1000hrs) was a period of peak visitations, followed by midday while dusk recorded the least visitations. Mammals utilized water pans for drinking, wallowing, grazing, socialization, and soil licking. There were significant differences in the number of visitations between the dry and wet seasons (df =7, t = 2.739, p=0.029) where dry season had high visitations (64.6%) while wet season had 35.4%. There was also a strong negative correlation between mammal visitations to the water pans and the time of the day.  The study shows that constructed water pans provide important source of water in protected areas where natural water sources are absent, inaccessible due to fencing, or during the dry season when water is limited. Therefore, water provisioning during the dry season in areas lacking water to increase dispersal ranges in the conservancy reducing mammal concentration around water pans.","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"4 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139389594","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}

Focused on the consequences of anthropogenic activities, our research assesses changes in forest cover using Landsat images from 1990, 2003, and 2019. Utilizing satellite data, calculation of indices such as Normalized Difference Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI), Normalized Difference Water Index (NDWI), and LST were performed. Land use land cover (LULC) was determined through supervised classification, achieving accuracies of 75%, 87%, and 83% for 1990, 2003, and 2019, respectively. The analysis highlighted a substantial increase in settlement area from 9.37 km2 in 1990 to 22.86 km2 in 2019, indicative of significant urbanization impacts.Our findings reveal a pronounced positive correlation between settlement growth and elevated LST, indicating the influence of urbanization on thermal dynamics. Additionally, positive correlations were observed between LST and NDBI, while a negative correlation existed between LST and NDVI. Questionnaire-based surveys complemented remote sensing data, exposing a gradual decline in wildlife sightings, diminishing populations of rare plant species, and the proliferation of invasive plants within and around the Wildlife Sanctuary since 1990.This research underscores the substantial impact of urbanization on the biodiversity of the Itanagar Wildlife Sanctuary. Positive correlations between settlement growth, LST, and biophysical parameters emphasize the urgency for targeted conservation strategies. The decline in wildlife sightings and the encroachment of invasive species underscore the need for proactive measures to balance biodiversity conservation with the challenges posed by urban development. Our integrated approach, combining remote sensing, survey data, and ecological indices, offers valuable insights for sustainable management and conservation efforts in similar habitats globally.","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"65 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138945746","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}

Through interviews with ten farmers, it was found that a majority of farmers were aware of climate change and had observed various climate-related changes over the past two decades. These changes included rising temperatures, decreased rainfall, prolonged droughts and increased occurrences of heat waves, among others. The impact of climate change on agriculture was evident in the form of water scarcity, declining water quality and increased susceptibility of crops and livestock to pest and disease attacks. Farmers noted specific challenges such as new diseases affecting crops, such as fall armyworm and wilt disease, which led to significant crop losses. Erratic monsoon patterns and hailstorms further exacerbated the situation, resulting in reduced agricultural yields and earnings. The deteriorating quality of food due to chemical farming practices was observed to have adverse effects on human health, with changes in food consumption habits contributing to an increase in diseases. Moreover, livestock diseases were more prevalent in recent years, likely linked to climate-related shifts. Farmers identified various drivers for climate change adaptation, including a lack of information and knowledge about climate change, accessibility to credit facilities and the outbreak of new diseases or food scarcity. While many lacked knowledge about climate change mitigation strategies, they had adopted practices like crop rotation, improved seeds and soil conservation technique.","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"2 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139001145","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}

Taking a step towards fostering sustainable practices in education institution involves reporting CF levels within college campuses. This research centers on computing the carbon footprint of Himachal Pradesh University's Shimla campus (2020-2023), with a focus on understanding emissions trends, particularly the transition from lockdown (2020–2021) to post-lockdown (2021–2022 and 2022–2023) periods amid the COVID-19 pandemic. The study aims to address the challenge posed by educational institutions' substantial energy demands, contributing significantly to GHG emissions. Achieving net-zero emissions remains a formidable task for educational institutions, even with options like remote work and learning. The study underscores the persisting challenge of insufficiently addressing these concerns, despite the potential for students to play a role in mitigating greenhouse gas emission issues with the right information and resources. The research employs the Greenhouse Gas Protocol method to compute the Scope 1 carbon footprint of energy sources, encompassing kerosene, petrol, diesel, and LPG. This approach empowers educational institutions and businesses to construct dependable inventories of their GHG emissions, facilitating progress monitoring and the cultivation of sustainable practices aligned with climate objectives. By utilizing the Greenhouse Gas Protocol, the study evaluates Scope 1 emissions from energy sources like kerosene, petrol, diesel, and LPG, offering a systematic approach for institutions to create reliable inventories aligned with climate goals. The findings highlight kerosene as the predominant contributor, prompting the study to recommend curbing the use of conventional energy sources and transitioning to alternatives. Additionally, the research conducts Scope 2 emission calculations to compare the carbon footprint resulting from electricity consumption, contrasting coal-based electricity generation with hydropower generation. Valuable insights are provided for universities to leverage calculated carbon footprints in identifying effective emission reduction strategies. The study identifies information gaps and inefficient data collection as significant challenges, proposing energy-saving measures and enhanced procurement strategies as beneficial mitigation measures.","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"29 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139009566","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}

Despite the importance of large cities, the greatest urban growth occurs in medium and small cities. During the last century these cities enjoyed acceptable air quality, however from the last years of the last century and the two decades of this century the atmospheric health has deteriorated, generating problems. The dynamics of population growth faced by these cities represent a serious threat to the environment, as well as to the health and quality of life of its inhabitants, since it generates new economic processes, accompanied by an increase in industrial activities, motorization rates, greater fuel consumption and higher emissions of air pollutants. \u0000Objective: To carry out an analysis of the air quality condition and to show the trends of the criteria pollutants for 10 medium-sized Mexican cities with the highest population growth. \u0000Materials and Methods: The data for the analysis of air quality of medium-sized cities were downloaded from the consultation system of Air Quality Indicators-SCICA through the http://scica.inecc.gob.mx/exec/addl website. The downloaded data are hourly concentrations of the six criteria pollutants PM10, PM2.5, O3, SO2, NO2 and CO for the monitoring stations of the cities of Aguascalientes (863 893 h), Mexicali (854 186 h), Ciudad Juárez (1 501 551 h), Chihuahua (925 762 h), León (1 579 803 h), Morelia (743 275 h), Puebla (1 542 232 h), Querétaro (794 789 h)), San Luis Potosí (854 186 h) and Torreón (690 193 h), indicators were calculated of the daily, monthly and annual trend, averages, percentages of days with concentrations above the norm and number of days per year in which any of the norms is exceeded during the period 2000-2020. Compliance with environmental health NOMs (at one hour, 8 h, 24 h and annually) was evaluated depending on the pollutant criterion. \u0000Results and Discussion: Medium-sized cities have grown between 21 and 55% in the last 20 years, some surpassing the category of medium cities. The concentrations of PM10, PM2.5 and O3 in all medium-sized cities are almost always above the normativity which represents a risk to the health of the population. The concentrations of CO, NO2 and SO2 are below the limits of the regulations, so these pollutants currently do not represent a risk to the population of medium-sized cities.
