The purpose of this study was to determine the public perception of the difficulty of successful reforestation activities in the Lake Toba catchment area. The data were taken from primary and secondary data. Primary data were information collected by reforestation activities in the villages, secondary data were collected in the study site general conditions existing at the village government agencies, of which sampling method was done by purposive sampling, i.e., sampling deliberately chosen. The results showed a lack of socialization in the extension of government reforestation activities, uncontrolled forest fires, lack of maintenance of seed that has been planted, and the type of plant is less suitable.展开更多

Based on surveys of the public in Canada,Mexico, and the United States, the article shows the levels of concern over climate change threats, perceived risk,knowledge of climate change policies, levels of uncertainty, and other perception factors to help understand the relationships between public perceptions and policy preferences for renewable energy. Results show national differences between the three countries in nearly all climate change perceptions, with Mexico reflecting the highest levels of concern and the United States the lowest. Mexico also shows the greatest support for renewable energy sources. However, the results show very high levels of uncertainty about climate change dimensions concerning risk, science, and knowledge and the effectiveness of policy approaches. The data demonstrate strong statistical correlations between risk perception factors and preferences for mitigation policies in the form of renewable energy policies.展开更多

The solicitation of public views was based on household surveys using a standard questionnaire which was administered to 115 randomly selected respondents. The dominant wildlife species according to 39% of the respondents was the elephant followed by the zebra with 35%. 40% of the respondents indicated that the rhino population had declined followed by wild dogs (7%) and cheetah (6%). The actual counts showed that the herbivores with increasing populations included the rhino (r<sup>2</sup> = 0.9992), impala (r<sup>2</sup> = 0.9824), Thomson’s gazelle (r<sup>2</sup> = 0.6965), Grant’s gazelle (r<sup>2</sup> = 0.7052), elephant (r<sup>2</sup> = 0.5798), and topi (r<sup>2</sup> = 0.4426) while the increasing predators included the lion (r<sup>2</sup> = 1.000), cheetah (r<sup>2</sup> = 0.9093) and hyena (r<sup>2</sup> = 0.8462). The actual wildlife counts appeared to tally with the public views only for the elephant and zebra. The actual counts contradicted the public views in terms of the rhino, lion and gazelles whose numbers were on the increase but the people did not appear to notice. Based on this, it was concluded that the public view on the wildlife population trend was not similar to the actual wildlife population status on the ground based on scientific monitoring.展开更多

Nevertheless, due to some problems the program is immaterialized so far. Recently, in anticipation of domestic energy crisis, nuclear program is revitalized. In the current situation, nuclear program is facing various challenges, including public perception, political instability, brain drain of skilled people, governmental support, and international confidence. In coping with these challenges, several efforts have been done. For instance, to deals with public perception, BATAN is making continuous effort in convincing the public and the decision makers to be aware of the necessity of nuclear power. In line with such effort, several milestones of the nuclear power programme have also been achieved. One of the most important milestones is the enactment of Act No. 10/1997 on Nuclear Energy. The Act demands the establishment of independent regulatory body separated from promoting body.展开更多
