Land-use and environmental pressures resulting from current and future bioenergy crop expansion: A review

Recent energy and climate policies, particularly in the developed world, have increased demand for bioenergy² as an alternative, which has led to both direct and indirect land-use changes and an array of environmental and socio-economic concerns. A comprehensive understanding of the land-use dynamics of bioenergy crop production is essential for the development of sustainable bioenergy and land-use policies. In this paper, we review the patterns and dynamics of land-use change associated with bioenergy crops (hereafter referred to as ’bioenergy-driven land-use change’). The review focuses on four regions as the most prominent locations in which these patterns and changes occur: Brazil; Indonesia and Malaysia; the United States of America (U.S.A.); and the European Union (EU). The review confirms that bioenergy-driven land-use change has affected and will impact most severely on the ’land- and resource-abundant’ developing regions, such as Brazil, where economic development takes priority over sustainable land-use policies, and the enforcement capability is limited. Opportunities for more effective policy are available through the development of international climate change policy (e.g. REDD under the UNFCCC), and certification criteria for sustainable bioenergy products (e.g. EU RED). However, bioenergy produced from no and/or less land-using feedstocks (e.g. wastes and residues), and their associated technologies must be given higher priority to minimise bioenergy-driven land-use change and its negative impacts.     

乡镇政府在农业公共服务供给中的角色定位

在国际金融危机影响下,我国经济发展面临着巨大的挑战。要实现我国经济平稳较快发展,基础支撑在农业。农业公共服务供给是关系到我国农业生产经营稳定发展的关键环节,也是我国公共服务型政府建设的必然要求。乡镇政府作为我国基层政府,一直以来在农业公共服务供给中扮演着重要的角色。本文从农业公共服务的定义出发,廓清了农业公共服务的范围,将建国后至现阶段我国乡镇政府在农业公共服务供给中的角色变迁进行疏理,进而提出现阶段我国乡镇政府在农业公共服务供给中的角色定位。     

外贸函电的拒绝策略及语用分析

拒绝是威胁听者积极面子的言语行为,因而要采取各种策略进行补救。外贸函电的拒绝策略分为直接策略和规约策略。规约策略由于同时遵守了合作原则和礼貌原则,从而减少了对于对方面子的威胁,因而在外贸函电中被广为使用。     

我国新型农民合作社的形态、功能及其发展

按照性质不同,我国的农民合作社可划分为新型农民合作社和传统农民合作社两大类型.新型农民合作社的基本功能是农户间的团结协作和互利互惠,它有利于促进农业产业化经营;抵御农业经营风险;实现农民共同富裕;推进农村民主政治建设.从我国的情况看,在发达国家农业产业化经营的三种模式--综合型模式、合同型模式和合作社型模式中,合作社型模式更适合我国的农业产业化经营.由于当前在发展新型农民合作社中存在的,诸如合作的认识不够明确、合作的环境不够优良、合作的机制不够完善的问题,这需要通过教育普及国际公认的合作经济理论和实务知识;尽快出台<农村资金合作社法>,明确各类农民合作社的主管部门;建立、健全合作社"三会"制度及议事规则.

河北省农业保险的现状与风险分散机制

针对2008年河北省出台的农业保险的政策以及河北省的农业保险的实际情况,通过分析现状发现存在开展农业保险的公司高度集中、赔付率比较高;农户保险意识淡薄、投保能力不足;政府扶持农业保险的效率低,配套措施未到位等问题。结合我国农业保险开展的实际和河北省的情况提出从农业保险立法、扶持的财政和税收政策的加强、多层次风险分散体系建立以及大力发展互助性质的农业保险互助社等措施来完善河北省农业保险的风险分散机制。     

农地经营权流转与宁夏生态移民发展研究

笔者通过对宁夏生态移民迁入地发展滞后的现状分析,发现农地建设与经营成本负担是制约生态移民迁入地发展的主因。根据制度变迁理论,结合十七届三中全会决议,文章探讨了生态移民农地经营权流转制度,提出采取“农地收购”、“招募式移民安置与农地产业化经营模式”是解决当前农地短缺和生态移民发展问题的有效途径。     

基于农业产业集群的我国农村剩余劳动力就业问题研究

解决“三农”问题关键是解决农村剩余劳力就业,然而受美国金融危机影响,农村剩余劳动力就业困难更加突出。在各种解决问题的途径中,发展农业产业集群是比较有效的。本文深入分析了农业产业集群吸纳农村剩余劳动力就业的作用机理和面临的障碍．提出了制定科学的农业集群规划、创造良好的发展环境、鼓励返乡农民就地创业等建议．以解决农村剩余劳力就业问题。

The Association Between the New Rural Cooperative Medical System and Health Care Seeking Behavior Among Middle-Aged and Older Chinese

The new rural cooperative medical system (NCMS) is the primary form of social insurance in rural China. This study aims to explore how the NCMS influences the health care seeking behaviors of middle-aged and older Chinese, considering the family and community contexts. A series of multi-level (three-level) models using data from the first wave of the China Health and Retirement Longitudinal Study (CHARLS) are used. We find that the presence of NCMS coverage has a statistically significant association with seeking inpatient and outpatient care but not physical checkups among middle-aged and older rural Chinese: Rural residents insured by NCMS were more likely to seek inpatient and outpatient care than people who were not insured. Other factors at the individual level (such as self-perceived health and number of doctor-diagnosed chronic diseases), the family level (such as living arrangements and household expenditures), and the community level (such as the presence of township hospitals within the community) are also significant predictors of health care seeking behaviors.
