In West Africa, smallholder farmers in indigenous agricultural societies typically hold considerable knowledge. Therefore, this study was conducted in West Atacora of Benin Republic to assess the drivers of farmers’ perceptions of climate change risk. We used a random sampling technique to select 360 households’ heads who were interviewed regarding different climate change risks perception. Binomial logistic regression was used to assess the drivers of farmers’ perceptions of climate change risks. The results showed that the farmers in drier areas had a higher perception of the global risk of climate change than those in humid areas. The same trend was observed for the seven different individual’s climate change risk investigated. The study identified also membership of farm organizations as main sociodemographic characteristic that explains farmers’ perception of climate change risk perception. These findings are helpful tools to sensitize the local people on climate change risk and cope with the risk in agricultural lands.展开更多

It is disappearing gradually, because of overharvesting, environmental pollution, specially river pollution, activity of human exploitation, and so on. We conducted community interview fieldworks to collect respondent data from Xieba Country(not reserve) situated in Zhengan County of Guizhou Province, where one of the places known by historical giant salamander records in Guizhou. Through the analysis of the collected data, we created quantitative data of use for conservation management on the local status of salamander populations, and we compared our data with those available data of Y. Pan et al., who investigated the status of CGS in 3 reserves in Guizhou Province in 2015.The conclusions have a similar trend, which proved that the collected data were creditable. Through statistical analysis of the comparison data, the number of wild CGS decreased actually followed the increase of artificial framing.Because of the source of breeding to catch wild CGS, overharvesting was likely the most reason to make wild CGS decline.展开更多

They are quite different from other common ecotourism areas, because of its original and unique system, sensitive and vulnerable landscape, and peripheral cultural features. Therefore, the tourism development in the nature heritage sites should be on the premise of ecological security. The evaluation index system of tourism ecological security in nature heritage sites was constructed in this article by AHP and Delphi methods, including nature ecological security, landscape visual security and local culture ecological security, and the security thresholds of indices were also established. In the indices' weights of the evaluation model, the nature ecological security ranked the highest, followed by tourist landscape visual security and culture ecological security, which reflected the influence degree of the limited factor to tourism ecological security. Then, this paper carried out an empirical study of Kanas of Xinjiang Uygur Autonomous Region, China, which has the potential to be the World Nature Heritage. On the basis of the data attained from survey and observation on the spot, as well as questionnaire answered by tourists and local communities, the ecological security status in Kanas was evaluated. The result showed that the status of Kanas tourism ecological security was better, but there had some limiting factors. Lastly, effective measures were put forward to ensure its ecological security.展开更多
