农村生态文明建设视域下改善农村干群关系的思考

建设社会主义新农村需要生态文明,当前我国农村生态文明建设还面临着很大问题和挑战.农村生态态文明建设需要加强广大农村干部与农民群众的密切联系,改善农村干关系事关重大.     

农村合作经济组织发展的制度分析

农村合作经济组织是将农民组织起来进入市场、参与竞争的桥梁和纽带,是新时期推动农村经济发展和提高农民收入的重要因素之一。在制度层面运用新制度经济学理论从实现土地规模经营、节约市场交易费用和维护农民利益等三方面分析了合作组织发育的需求诱致性动因;接着从制度环境状况、现有社会科学知识的积累、现存的制度安排、组织的制度变迁成本、非正式制度安排等外部制度供给方面以及产权和组织制度等组织内部制度方面分析了其存在的缺陷;最后提出了推动合作组织发展的政策建议：其一,只要是以“三农”服务为宗旨,政府在政策上都应允许和指导合作组织灵活地创新产权制度、因地制宜地进行多种形式的组织创新;其二,政府要力所能及地为合作组织提供一些制度服务。     

交易费用视角下农地整理管护绩效的影响因素研究

农地整理建成设施及设备的管护是权利让渡和责任主体迁移的过程,对农地整理管护绩效开展研究是破解当前管护困境的有效途径。论文在构建农地整理管护绩效测度体系及其评估方法基础之上,运用威廉姆森交易费用“维度论”分析框架阐述农地整理管护绩效的影响因素。实证研究结果表明,实物资产专用性、人力资产专用性、交易不确定性、交易频率等维度要素对管护绩效的影响较为显著;论文运用工具变量方法解决计量模型中解释变量内生性问题,探讨了内生变量与工具变量以及其他解释变量的作用关系。研究结果验证了威廉姆森分析框架的有效性,并建议管理部门重视耕地生产水平的改善程度、村干部的表率示范作用以及管护人员的明确落实等关键影响要素。     

沂蒙山区农户生计变迁及其住宅形态的响应研究

以山东省沂水县3个村（核桃园、高桥、唐家庄子）为例,运用参与式农村评估法（PRA）、对比分析法,剖析沂蒙山区农户生计变迁与其住宅形态功能转型的关系,为农村居民点整治中的新村建设提供决策指导。研究结果表明：1）改革开放前,研究区农户以农业生计为主,修建“平房+庭院”形态住宅,利用庭院种植蔬菜;2）改革开放后,农户生计逐渐多样化和非农化。禽畜养殖成为农户重要的生计来源,农户在住宅内搭建猪圈养猪,在庭院内饲养家禽。高桥农户就地发展非农经济,修建两层楼房,将一层的空间用于非农经营;3）21世纪以来,农户生计进一步非农化和分化。核桃园农户以粮食种植和外出务工为主,将庭院硬化晾晒粮食,改造猪圈为储物间储存粮食和农机具;高桥农户为了扩大非农经营空间修（改）建三层楼房,将一二层用于非农经营;唐家庄子农户到县城非农就业,为改善居住环境修建两层楼房,住宅中用于生产的空间消失。可见：农村住宅形态和功能转型是与农户生计方式变迁相适应的,农村居民点整治中新村建设模式应充分考虑农户生计的实际需求。     

流动性视角下乡村旅游地游客地方感差异分析

基于流动性理论,以400份北京居民的调查问卷为样本,分析了乡村旅游者流动中的地方感差异,从游客地方感角度为流动市场中的乡村发展寻找途径。结果表明:不同游客群体间存在明显的地方感差异,且地方感知(自然维度、人文维度、服务感知)对地方情感(地方依恋、地方忠诚)存在显著影响,地方情感对重构乡村地方、延续乡村性具有重要意义。基于研究结论,建立乡村旅游者地方感研究模型。     

中国农村生态环境质量动态评价及未来发展趋势预测

客观评价和预测我国农村生态环境质量状况及发展趋势,对于保障粮食安全、实现农村经济可持续发展具有重要的理论和现实意义。论文基于压力-状态-响应（PSR）模型框架,构建了我国农村生态环境质量评价指标体系,分析了2000—2015年我国农村生态环境质量的动态变化。基于GM(1,1)模型,预测了“十三五”期间我国农村生态环境质量的发展态势。研究结果表明：2000—2015年我国农村生态环境质量的综合评价得分从0.669下降到0.387,农村生态环境质量总体呈现恶化趋势,农村生态环境承受的污染排放压力越来越大,环境治理投入较少,尚未形成对农村生态环境恶化情形的逆转。如果继续延续过去农业经济发展模式,2020年我国农村生态环境质量状况将会持续恶化,与“十三五”绿色发展的良好愿景目标相差甚远。     

Organochlorine pesticide residues in fodder from rural areas of Haryana,India

Residues of organochlorine pesticides (OCPs) namely 1,2,3,4,5,6-hexachlorocyclohexane isomers (HCH-isomers), 1,1,1-trichloro-2,2-bis(p-chlorophenyl) ethane (DDT) and its metabolites, and endosulfan stereoisomers were analyzed in dry and green fodder samples from rural areas of Ambala, Gurgaon, and Hisar districts of Haryana, India during winter, summer, and post-monsoon seasons. The HCH isomers γ-HCH and β-HCH, and DDT and its metabolites p,p′-DDD, p,p′-DDE, and p,p′-DDT had more traceability in test samples as compared to other isomers and metabolites studied. Total OCPs (ΣOCPs), i.e., ΣHCH, ΣDDT, and Σendosulfan were found to be the highest in wheat straw (1.1–1.2?mg?kg^?1) from Ambala and Gurgaon, followed by that in sorghum straw (0.46?mg?kg^?1) from Hisar. Dry fodder samples were found to have relatively higher residue levels than green fodders. In case of green fodder samples, maximum ΣOCP residues of 0.44?mg?kg^?1 were found in whole plant samples of sorghum from Gurgaon district followed by that in pearl millet (0.40?mg?kg^?1) from Ambala. The findings indicate highly significant differences (p?>?0.0001) in ΣOCPs and ΣDDT in wheat straw between different districts and reveal the persistence of OCP residues in both dry and green fodder samples in the study area.     

Landscape fires as social disasters: An overview of ‘the bushfire problem’

The ‘landscape’, ‘bushfire’ or ‘forest-fire’ problem is exemplified by the destruction of homes and human lives by landscape fires raging out of control. The ‘problem’ involves a series of landscapes (e.g. wildland and suburb), a series of systems (e.g. biophysical system and environmental-effects system), and a series of time phases (e.g. planning phase). It is a multi-stakeholder, multi-variable, multi-scale problem. Land uses, like ‘farmland’, imply a set of specific assets and, therefore, particular perceptions of losses. In all land-use designations, at any one point, fire-proneness may be seen as a function of exposure to ignition sources (embers, burning brands or flame radiation and flame contact) and the ease of ignition. The landscape-fire problem has multiple partial ‘solutions’, not just one overall solution, and these involve social governance, land management (public and private), suppression capacity and personal preparedness. The problem needs to be addressed at multiple temporal and spatial scales in an integrated fashion for the outcome to be of maximal benefit. There will always be a residual risk of severe fire occurrence. Minimisation of residual risk requires effective land management, recurrent funding and the perpetual vigilance of all parties.     

Managing natural resources with eco-friendly technologies for sustainable rural development: a case of Garhwal Himalaya

Traditional Central Himalaya societies face a range of socio-economic and environmental problems. The potential of science and technology has not yet been adequately and appropriately harnessed to overcome the development constraints posed by the fragile Himalayan environment. Thus there is a need for large-scale establishment of technology resource centers. The Garhwal Unit of GB Pant Institute of Himalayan Environment and Development established rural technology demonstration and training centers in three different agroecological zones between 550 and 2200 m asl and in 13–15 locations, with suitable technologies based on appropriate use and management of locally available bio-resources that ensure people participation. About 35 on-site training courses were organised for about 2329 participants. The participants were given on-site demonstrations, training and technical know-how on various technologies, to enable farmers to better understand problems faced during implementation of new technologies for sustainable management of natural resources. An action research framework and training manuals were also developed in consideration of local socio-economic condition. The documentation and analysis of research (quantitative and qualitative) and data related to cost–benefit analysis of the technologies adopted by farmers generated through this study has created wider sharing of farmer training outputs, at farm level, amongst the scientific communities and with policy planners.
