| 1 | 印度尼西亚沿海村庄中的人口迁徙和捕捞活动显示文摘东南亚的沿海生态系统正处于来自局部和全球变化增长的压力下。本文研究了印度尼西亚北苏拉威西省米纳哈萨区沿海村庄中的人口迁徙和海洋资源利用情况。原始数据是通过对村庄领导人、重点人群的采访以及600个捕鱼家庭的抽样调查收集的。在过去10年经济增长总量中至少有1/4应归功于人口迁徙。所有渔民团体都报道说近岸渔业生产力正在下降。经济计量学分析被用来研究手工捕鱼部门的周渔获量。人口迁徙状态和社会经济变量看来不产生系统的影响,而渔捞能力(劳动力、渔船及渔具),专业化程度以及村庄地处遥远被认为确实与周渔获量大小有关系。 | Randall A.Kramer Sahat M.H.Simanjuntak Christopher Liese 林宝法 | 2002 | AMBIO-人类环境杂志2002，31，4： | 0 |
| 2 | Household perceptions and subjective valuations of indoor residual spraying programmes to control malaria in northern Uganda显示文摘Background:Insecticide-based tools remain critical for controlling vector-borne diseases in Uganda.Securing public support from targeted populations for such tools is an important component in sustaining their long-run effectiveness.Yet little quantitative evidence is available on the perceived benefits and costs of vector control programmes among targeted households.Methods:A survey was administered to a clustered random sample of 612 households in Gulu and Oyam districts of northern Uganda during a period of very high malaria transmission and following a pilot indoor residual spray(IRS)programme.A discrete choice experiment was conducted within the survey,in which respondents indicated their preferences for different IRS programmes relative to money compensation in a series of experimentally controlled,hypothetical choice sets.The data were analysed using conditional logit regression models to estimate respondents’willingness to accept(WTA)some amount of money compensation in lieu of foregone malaria risk reductions.Latent class models were used to analyse whether respondent characteristics predicted WTA.Results:Average WTA is estimated at$8.94 annually for a 10%reduction in malaria risk,and additional co-benefits of IRS were estimated to be worth on average$54–$56(depending on insecticide type)per round of IRS.Significant heterogeneity is observed:Four in five household heads in northern Uganda have high valuations for IRS programmes,while the remaining 20%experience costly side effects of IRS(valued at between$2 and$3 per round).Statistically significant predictors of belonging to the high-value group include respondent gender,mean age of household members,participation in previous IRS,basic knowledge of mosquito reproduction,and the number of mosquito nets owned.Proxies for household income and wealth are not found to be statistically significant predictors of WTA.Conclusions:This study suggests that the majority of people in areas of high malaria transmission like northern Uganda place a high value on vector control programmes using IRS.However,there is significant heterogeneity in terms of the perceived side effects(positive and negative).This has implications for sustaining public support for these programmes in the long-term. | Zachary S.Brown Randall A.Kramer David Ocan Christine Oryema | 2016 | Infectious Diseases of Poverty2016，5，1： | 0 |
