This thesis investigates the demand for water supply improvements in Queretaro, Mexico. Queretaro currently lacks adequate water supply services, and it is of interest to know if residents would be willing to finance improvements to the water supply system.
The data for this work were collected with two in-person surveys of Queretaro's households. The first survey was administered to a stratified random sample of 629 homes with piped water services. The second survey was conducted with a semi-random sample of 207 households in informal settlements that do not have private water services. This thesis is one of the first studies in Mexico that demonstrates that residents are willing to pay a significant amount of money for water supply improvements. This study also provides some of the first evidence from Latin America that residents from informal settlements are willing to pay a considerable proportion of their income for water service improvements. 相似文献

Costa Rica has long been a leader among developing countries in the design of and experimentation with innovative environmental programs. Since 1997, Costa Rica's "Pagos de Servicios Ambientales" (Payments for Environmental Services) Program has provided payments to more than 4,400 farmers and forest owners for reforestation, forest conservation, and sustainable forest management activities. The econometric analysis of a survey of farmers and forest owners, including both PSA participants and nonparticipants, shows that farm size, human capital and household economic factors, and information variables significantly influence participation in PSA program alternatives. Large farmers and forest owners are disproportionately represented among program participants. 相似文献

论四川的粮食供求平衡问题 总被引：1，自引：0，他引：1
一、粮食供求目标模式的选择一个省的粮食供求目标的研究,是带有总体性、全局性的问题,属于宏观经济管理的范畴。实现区域性的供求平衡就是实现价值平衡与实物平衡的统一、总量平衡与结构平衡的统一、静态平衡与动态平衡的统一、当前平衡与长远平衡的统一。据此研究四川的粮食供求关系,提出四川粮食供求目标为:供求平衡,略有节余。为什么四川作为一个区域性的市场领域,要提出这样一个供求目标呢?主要有以下几点考虑:1.粮食生产能力强,总产量规模大,但商品供应量小四川生产能力强表现出三个特点:一是生产总量大。粮食总产连续10多年都在300亿… 相似文献
