城市积水考问政府公共服务能力

城市积水处理是城市基础设施建设的一部分,也是政府公共服务的一部分,更是对政府提供公共服务的能力和水平的考问和检验,面对严竣的积水现状,我国政府唯有强化公共服务能力,完善公共服务体系,才是治理之道。     

从“救济”到“治理手段”？——当前农村低保政策的实践分析：以河南F县C镇为例

作为国家推行的一项福利政策,农村低保要实现对农村贫困人群的救助。然而,在现实中,低保政策经历了从“绝对贫困”到“相对贫困”、从以户为单位到以人为单位的扭曲和变通,以至低保政策在某种程度上成为了基层政权的一种治理手段,从而背离了政策的本意。事实上,低保政策执行中出现的种种问题既是监管力度不够及制度建设不到位所导致,更与税费改革后乡村组织的治理困境密切关联。在这个意义上,基层政权的治理状况既是保障低保政策能否顺畅执行的根本,也是一个现代国家基本治理能力强弱的重要体现。     

城中村失地农民社会保障模式比较研究——基于CTPLCSI框架的分析

城中村失地农民作为一种特殊群体,对土地保障的替代机制具有更加强烈的需求,在替代保障机制的选择或构建中具有得天独厚的优势。文章在CTPLCSI框架的基础上对我国当前17个省市的城中村失地农民社会保障模式的政策和实践类型进行了梳理、归纳、比较和分析,认为,构建城中村失地农民社会保障模式,应树立“公平正义、兼顾效率”的保障理念,坚持“因地制宜、分类保障、立法护航、稳步推进”的指导原则,实现“福利改进、城乡统筹”的模式目标。

Economic effects estimation for the Eurasian Economic Union: Application of regional linear regression

This paper aims to provide a coherent analysis of the economic impact accession to the Eurasian Economic Union has had on the economies of current member states and what affect membership would have on the economy of Azerbaijan. By applying a Linear Regression Model we find that membership to this regional bloc has yielded minimal financial benefits for the existing members. However, for most states, accession has increased the trade deficit with Russia and that a membership would likely produce a similar negative outcome for Azerbaijan in addition to undermining national economic and energy policy making.     

African farmer-led irrigation development: re-framing agricultural policy and investment?

The past decade has witnessed an intensifying focus on the development of irrigation in sub-Saharan Africa. It follows a 20-year hiatus in the wake of disappointing irrigation performance during the 1970s and 1980s. Persistent low productivity in African agriculture and vulnerability of African food supplies to increasing instability in international commodity markets are driving pan-African agricultural investment initiatives, such as the Comprehensive Africa Agricultural Development Programme (CAADP), that identify as a priority the improvement in reliability of water control for agriculture. The paper argues that, for such initiatives to be effective, there needs to be a re-appraisal of current dynamics of irrigation development in sub-Saharan Africa, particularly with respect to the role of small-scale producers’ initiatives in expanding irrigation. The paper reviews the principal forms such initiatives take and argues that official narratives and statistics on African irrigation often underestimate the extent of such activities. The paper identifies five key characteristics which, it argues, contradict widely held assumptions that inform irrigation policy in Africa. The paper concludes by offering a definition of ‘farmer-led irrigation’ that embraces a range of interaction between producers and commercial, government and non-government agencies, and identifies priority areas for research on the growth potential and impact of such interactions and strategies for their future development.
