Study on the potential of bio-fuel production and the sustainability of developing countries in Asia

这项研究考察了菲律宾的甘蔗和椰子等能源作物的生产结构，并从环境和经济发展的角度讨论了实现这些作物可持续生产目标的政治条件。前沿生产分析的结果表明，针对甘蔗种植者的技术推广政策，如生产培训计划，效果不是很好，因为平均技术效率已经达到很高的水平。另一方面，椰农的技术效率相对较低，因此，应该在他们中间推广椰农的良好做法。然而，联合生产的根本问题是椰子树的树龄。从长远来看，老树应该被年轻的树取代，以可持续地增加产量。此外，我们还应特别关注农民对生物燃料的认知及其对增产的制约。

This study examined the production structure of energy crops, such as sugarcane and coconuts, in the Philippines, and discussed political conditions to achieve the goal of sustainable production of the crops in terms of the environment as well as economic development. The results of frontier production analyses show that technical extension policies, like production training programs, for sugarcane farmers is not effective so much since the average of technical efficiencies has already reached high. On the other hand, the technical efficiency of coco-farmers is relatively low, and therefore, the good practices of coco-farming should be spread among them. The root problem of coco-production, however, is the age of coconut trees. Old trees should be replaced by young ones to increase production sustainably in the long-run. Furthermore, we should pay special attention to farmers' perception of biofuel and their constraints for production increase.
