Media plays a vital role in informing the public about environmental threats. Although climate change is a global problem, developing countries such as India are often more vulnerable to the impacts due to poverty, illiteracy, and low public awareness. Using data from a nationally representative survey in India, this paper explores the relationships between media use, issue attention, and trust in informational sources on one hand and science-based climate change beliefs, risk perceptions, and policy support on the other. Results suggest that the Indian media, through consistent and accurate coverage of global warming using trusted sources, can play a positive role in increasing public engagement among a largely unaware population. Implications for climate change communication in India are discussed. 相似文献

Introduced plants that have both production values and negative impacts can be contentious. Generally they are either treated
as weeds and their use prohibited; or unfettered exploitation is permitted and land managers must individually contend with
any negative effects. Buffel grass (Cenchrus ciliaris) is contentious in Australia and there has been no attempt to broadly and systematically address the issues surrounding it.
However, recent research indicates that there is some mutual acceptance by proponents and opponents of each others’ perspectives
and we contend that this provides the basis for a national approach. It would require thorough and on-going consultation with
stakeholders and development of realistic goals that are applicable across a range of scales and responsive to regional differences
in costs, benefits and socio-economic and biophysical circumstances. It would be necessary to clearly allocate responsibilities
and ascertain the most appropriate balance between legislative and non-legislative mechanisms. A national approach could involve
avoiding the introduction of additional genetic material, countering proliferation in regions where the species is sparse,
preventing incursion into conservation reserves where it is absent, containing strategically located populations and managing
communities to prevent or reduce dominance by buffel grass. This approach could be applied to other contentious plant species. 相似文献

Five pesticide formulations registered for use in Canada containing organophosphate-insecticide active ingredients azinphos-methyl, chlorpyrifos, diazinon, malathion and phorate were subjected to treatment by membrane bioreactor (MBR) technology. The target active ingredients were introduced to the MBR at ppm level concentrations. The biodegradation of these compounds was analyzed daily using selected ion monitoring gas chromatography-mass spectrometry (GC/MS-SIM) following extraction of the analytes using solid-phase extraction (SPE). Amounts measuring 83 % to 98 % of the target analytes were removed with steady-state concentrations being reached within 5 days of their introduction. The dissolved oxygen, temperature, pH, and total heterotrophic bacterial population were monitored daily to ensure optimal conditions for biodegradation. The quality of the effluent from the MBR was assessed daily through spectrophotometric methods. Measurements were conducted for the concentration of ammonia, nitrate, nitrite, total and reactive phosphorus, as well as the chemical oxygen demand (COD) of the effluent. This study demonstrated that the MBR technology is feasible and efficient for treatment of organophosphate pesticides without introducing additional chemical additives. 相似文献

Sustainable development has broad consensus in environmental science and policy discourse, but its implications differ in specific cultural contexts. This article articulates sustainable development from a Chinese cultural perspective by tracing ideas from Chinese traditional culture and exploring China’s concept of harmonious development with emphasis on environmental management. Ideas that resemble sustainable development are not new to Chinese culture, but have roots in ancient Chinese thoughts, which in turn influence current governance and policies. Notably, Chinese traditional philosophies such as Confucianism, Taoism, Legalism, and Yin–Yang contain philosophies fundamental to sustainable development. As a distinct local discourse, such concepts were well interpreted and understood in the ancient meaning of harmony, giving China unique sustainability perspectives with institutional implications for policies of harmonious development and environmental management. Currently, China is driven to create a new national identity of harmonious development that involves Chinese traditional philosophies and values in its modern administration. The slogans “harmonious society” and “Chinese dream” reflect this new way of responding to the world with the aspiration to achieve cleaner growth, personal prosperity, and social stability. The Chinese and Western roots of sustainable development are conceptually, ideologically, and historically different, and this paper articulates how the convergence of the two underlies contemporary international debates. 相似文献

The Buffalo River and its dams are major surface water sources used for fresh produce irrigation, raw water abstraction and recreation in parts of the Eastern Cape Province in South Africa. Over a 12-month period (August 2010 to July 2011), we assessed the bacteriological qualities of water from the river and 3 source water dams along its course. Faecal indicator bacteria (FIB), including total coliform (TC), faecal coliform (FC) and enterococci (ENT) counts, were high and ranged as follows: 1.9?×?102–3.8?×?107, 0–3.0?×?105 and 0–5.3?×?105?cfu/100 ml for TC, FC and ENT, respectively. Significantly (P?<?0.05) higher concentrations of FC and ENT were observed at the sampling sites located at the lower reaches of the river compared to the upper reaches, and at Bridle Drift Dam compared to the other two dams. FIB counts mostly exceeded the recommended maximum values suggested by national and international guidelines for safe fresh produce irrigation, domestic applications, full-contact recreation and livestock watering. These results show that the bacteriological qualities of the Buffalo River and dams were poor, and suggest that sewage was dumped into the Buffalo River during the study period. Urban runoffs and effluents of wastewater treatment plants appear to be important sources of faecal contamination in the river. We conclude that these water bodies represent significant public health hazards. Provision of adequate sanitary infrastructure will help prevent source water contamination, and public health education aimed at improving personal, household and community hygiene is imperative. 相似文献

A simple but effective sampling and analytical procedure is described for determining total organics, carbon dioxide, carbon monoxide, and methane emitted from web offset printing presses. Data are reported on a number of controlled and uncontrolled sources and emission levels are related to process variables such as press speed, ink coverage and dryer type. For controlled sources employing either catalytic or thermal incineration units, conversion efficiencies are reported as a function of temperature. Operational curves are presented for each control system studied indicating the dependency of carbon dioxide, NOxt and organic output to incineration temperatures. 相似文献

During the late spring and early summer of 1974, complaints of noisy hi-vols were being reported at an average of five or six per week. Some public reaction to noisy hi-vols was manifest by physical damage being done to samplers and to monitoring site locations as well. 相似文献

This paper reports on immediate and long‐term well‐being outcomes for a group of long‐term unemployed youth who attended specially devised training courses based on the cognitive‐behaviour therapy (CBT) model. The courses were aimed specifically at improving the mental health of participants, and providing them with coping skills to deal better with the negative consequences of prolonged unemployment. Results for participants were compared with a waiting‐list, control group. Outcomes investigated were well‐being (psychological distress, self‐esteem, positive and negative affect), and coping behaviours (social support, self care, recreation, and cognitive coping strategies). Behavioural plasticity effects were also examined by comparing outcomes for participants who had higher distress scores prior to the course with participants who reported lower scores at that time. Immediate benefits were identified for both mental health and coping behaviours, and many of these benefits persisted into the long term. Participants with higher levels of pre‐course psychological distress improved more than their low distressed counterparts, supporting the behavioural plasticity hypothesis.
