In the framework of the canal environmental protection program of Ho Chi Minh City, we had developed 32 public awareness meetings for 14 districts with about 2,726 participants from year 2012 to 2015. The program had been organized in various forms such as training, brochure, leaflet, poster, propaganda gifts, face-to-face discussion, study visits, survey questionnaire. The results of the program can add substantial value to the canal environmental protection program of the city. The information gained through public comments can help identify key issues and solutions for the authorities as district and city levels. It was determined that most important outcomes from the public participation were educating the public, incorporating public values, assumptions and preferences into decision making process.展开更多

Specifically,for farmers/fishermen,posters/picture albums can benefit them more than the internet;the undergraduates also expect to learn wetland mainly through posters/picture albums;while for the primary and middle school students, the school education is another valuable source of publicity in addition to TV and radio.Strengthen cooperation with TV stations and broadcasting stations are the best way to raise public awareness of wetland conservation. The authors suggest to strength cooperation with media on wetland conservation,conduct wetland conservation education in middle and primary schools and communities;organize experts and professionals to write books and teaching materials needed for popularizing science,basic education and staff training;develop an internet-based CEPA network system on wetland conservation;conduct public awareness activities in communities,focusing on females in rural areas;build public awareness and education system,improve the public's awareness on wetland conservation,create good social environment for conserving wetlands.展开更多

Employing a descriptive methodology, the research investigates the interplay between public awareness, regulatory frameworks, and the availability of waste management facilities to assess their impact on waste management behaviors. Our findings indicate significant gaps in both knowledge and infrastructure that hinder effective waste management. The study reveals that while there is a high willingness among residents to engage in recycling and waste reduction, actual practices are limited due to inadequate facilities and lack of stringent enforcement of waste policies. This research identifies key factors that influence waste management practices, including demographic characteristics and access to waste management facilities. It also proposes actionable strategies such as expanding recycling and sorting facilities, enhancing educational campaigns tailored to local needs, and implementing regular enforcement mechanisms. These strategies are aimed at improving compliance with waste management protocols and fostering a culture of environmental responsibility. The results of this investigation show the critical role of ongoing education and infrastructural improvement in bridging existing knowledge gaps and facilitating effective waste management practices. This research lays a foundational step toward enhancing sustainable urban development and effective waste management in Windhoek, providing valuable insights for policymakers, community leaders, and stakeholders engaged in urban environmental management.展开更多

In China, great progress has been achieved since 1956 when the first nature reserve was established. However, conflicts between nature reserve officials and community members, and differences be-tween conservation and utilization of natural resources suggest that the traditional community affair model is unfit to some de-gree. A more workable and economically sustainable model is recommended. Co-management appears to be the preferred management model. International conservation organizations have carried out projects in Chinese nature reserves in recent years, and co-management is thought to be an effective approach to resolve conflicts coming from community and to improve nature reserves management.展开更多

The appropriate design of water management measures presupposes the investigation of the influence of some selected variables to consumers' behavior. The price of water, the size of the dwelling, the indoor and outdoor uses, the educational level, the income of consumers as well as rainfall and temperature levels are examined, the residential water demand curve is estimated and projections of future water demand under different pricing policies are performed.展开更多

文摘Severe acute respiratory syndrome coronavirus 2(SARS-COV-2)is a novel virus that emerged in China in late 2019 and caused a pandemic of coronavirus disease 2019(COVID-19).The epidemic has largely been controlled in China since March 2020,but continues to inflict severe public health and socioeconomic burden in other parts of the world.One of the major reasons for China’s success for the fight against the epidemic is the effectiveness of its health care system and enlightenment(awareness)programs which play a vital role in the control of the COVID-19 pandemic.Nigeria is currently witnessing a rapid increase of the epidemic likely due to its unsatisfactory health care system and inadequate awareness programs.In this paper,we propose a mathematical model to study the transmission dynamics of COVID-19 in Nigeria.Our model incorporates awareness programs and different hospitalization strategies for mild and severe cases,to assess the effect of public awareness on the dynamics of COVID-19 infection.We fit the model to the cumulative number of confirmed COVID-19 cases in Nigeria from 29 March to 12 June 2020.We find that the epidemic could increase if awareness programs are not properly adopted.We presumed that the effect of awareness programs could be estimated.Further,our results suggest that the awareness programs and timely hospitalization of active cases are essential tools for effective control and mitigation of COVID-19 pandemic in Nigeria and beyond.Finally,we perform sensitive analysis to point out the key parameters that should be considered to effectively control the epidemic.
