Multi-scale integrated analysis of rural Laos: Studying metabolic patterns of land uses across different levels and scales

This paper presents an application of the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) approach to the analysis of rural land uses. Using secondary data on farming systems in Laos, we illustrate how the concept of metabolic pattern can be used to establish links between the various indicators of performance of rural systems. To this purpose, we characterize the socioeconomic activities in rural Laos by a series of quantitative indicators defined across: (i) different hierarchical levels of organization described at different scales (i.e. households, rural villages, administrative regions and the whole country) and (ii) different dimensions of analysis, including economic, agronomic, social, biophysical, and ecological analysis. The MuSIASEM approach simultaneously employs two non-equivalent criteria for quantification. The observed rural system is described in terms of an integrated set of flow elements (money, food, energy, water, fertilizer and other materials), which are mapped against two distinct fund elements: (i) a multi-level matrix of human activity (flows being expressed in terms of intensity per hour) and (ii) a multi-level matrix of land uses (flows being expressed as density per hectare). Our case study shows that in this way it is possible to move across different hierarchical levels, scales and dimensions, to arrive at an integrated representation of the metabolic pattern of farming systems.

全面收集整理了2007-2015年威海市渔业资源、经济和社会统计数据,在分析海洋渔业资源特点基础上,利用层次分析法原理构建了威海市海洋渔业资源可持续利用评价指标体系,该指标体系包括资源环境子系统、社会子系统和经济子系统3个层次的24个指标,采用层次分析法确定各指标的权重,应用层次灰色综合评价模型首次定量评估了2007-2015年威海市海洋渔业资源可持续利用水平。结果表明:2007年,威海市海洋渔业资源可持续利用综合评价值为0.45,2008年,评价值降至近9年的最低值0.15,仅为2007年的33.2%,2009年评价值回升到0.48,2010年,再次下降到较低的水平0.17,仅为2009年的35.9%,2010-2014年评价值一直维持在极低的水平,海洋渔业资源可持续利用水平一直处于较低的状态,2015年,评价值达到最大值0.82,是最低值的5.54倍,海洋渔业资源可持续利用水平明显提高。     

基于资源视角的农业供给侧结构性改革的路径研究

[目的]粮食安全是世界各国政府普遍关注的问题,都将其列为重中之重.粮食主产区是我国粮食生产的核心地带和关键区域,为保障国家粮食安全、协调区域发展,必须从国家战略角度出发,实施粮食主产区利益补偿理念,充分体现社会公平与正义的价值取向和主旨,为粮食安全提供坚实的区域基础.[方法]运用实证分析方法,借助统计年鉴,通过粮食产量、人均粮食产量、粮食播种面积、人均粮食播种面积、人均地区总产值、地区财政收入、人均地区财政收入、城镇化率、居民人均可支配收入等数据分析,比较13个粮食主产区和7个粮食主销区在10年间粮食生产和经济社会发展的客观现实差距.[结果]粮食主产区在粮食产量、粮食播种面积等方面的生产规模优势和生产能力显著,对我国经济社会贡献巨大;粮食具有准公共产品的属性,粮食主产区需要支付高额的生产费用,承担运输成本与储存成本,无法通过市场获得补偿;粮食产销区之间囿于主体功能与发展责任的迥异而导致经济差距较大,主要体现在人均地区总产值、地区财政收入、人均地区财政收入、城镇化率、居民人均可支配收入等差别.[结论]据此提出,必须实施粮食主产区利益补偿,需要完善粮食主产区利益补偿的价值选择与国家政策导向:应在中央政府、区域政府层面完善相应的政策:一是国家层面制定粮食主产区区域政策;二是完善产粮大县奖励政策;三提高财政转移支付力度与精准度;四是建立产销区利益联动机制;五是加强农业基础设施和公共事业建设等.     

Transport impacts of government employment decentralization in an Australian city – Testing scenarios using transport simulation

Australia's largest cities are more mono-centric than most US cities and may be over-centralising, particularly in terms of office employment. Government worker relocation programs are being employed with policy debate over what should be an ideal urban structure including in terms of travel behaviour. The paper explores research approaches to explore transport impacts of employment decentralization. A review shows the results of: surveys of workers moved to suburban locations; longitudinal analyses of transport and land use changes in city-regions using cross-sectional census or HTS data; comparative analysis of urban structure variables across cities using similar datasets; combinations of longitudinal and comparative research; and, scenario-based modelling approaches. A modelling framework is then developed to appraise the possible transport impacts of decentralization in Brisbane. To test the possibilities further, two decentralization scenarios modelled and compared. Decentralization mostly to middle-suburban locations better addresses jobs-housing balance and maximises proposed new public transport services, producing good transport outcomes. However, decentralization to outer-suburban locations in Brisbane exacerbates the propensity for decentralization to increase travel distances, especially by car.

Grading Innovation in an International Marketing Course: Promoting Student Collaboration and Individual Accountability

In this article, the author proposes an innovative, exam-based homework grading method to facilitate both collaboration among students and individual accountability while learning a complex theory and applying it to solve a problem. Results from this novel approach to grading a comparative advantage theory homework assignment, using an objective exam performance measure to adjust original homework grades, show that students increase their comprehension of the frequently misunderstood theory. This novel grading method can be applied in a variety of contexts to promote student collaboration in preparation of academic work while providing incentives to encourage individual accountability and engagement.     

重大建设工程移民安置的社会福利分析——从土地价值角度出发

为了探讨基于土地价值的重大建设项目工程移民社会福利的变化,采用马克思的地租理论和实地走访调查的方式,测算土地价值,运用社会剩余表达移民和安置区原居民的社会福利,结合丹江口水库汉南移民的实际情况,得出结论:工程移民降低了移民和安置区原居民的社会福利;未遵守完全补偿和兼顾公平与效率的原则。基于这样的结果,最后提出:补偿方案应严格执行移民补偿标准、提高工程移民信息透明度和福利相关方参与度的建议。     

A comparative multidimensional evaluation of conservation agriculture systems: A case study from a Mediterranean area of Southern Italy

To avoid the current paradoxes of the global agro-food system it is necessary to define and implement a viable agricultural sustainable model, combining satisfaction of food needs and land preservation. A possible solution can be found in a holistic production system consistent with a sustainable development model, designed to satisfy diverse “local” economies. The conservation agriculture (CA) could be a part of this model, as it includes a set of best practices available to preserve agrarian soil and its biodiversity. Briefly, we cover the CA background in Europe followed by the evaluation of its impact in terms of private/public interest, using the sustainability’s metric.To test the viability of a model based on CA in “local conditions”, we compare economic performance of different conservation practices (i.e. minimum and no tillage) to that of conventional agriculture in a typical Mediterranean environment – Collina Materana – in Southern Italy (Basilicata region). Our findings suggest that: i) CA can actually be a viable alternative to conventional systems; ii) in Mediterranean agricultural areas CA has yield advantages especially during dry years, when conservation techniques increase water supply to crops; iii) public support is needed to direct farming choices in fact without financial incentives these practices would be not widely accepted and diffused; iv) European policy makers have to recognized the positive benefits of CA and pay them as ecosystem services in the framework of Good Agricultural Environmental Conditions and the present CAP subsidies.     

Environmental Analysis of Packaging for Soft Drinks Using the Life Cycle Assessment Methodology

The knowledge of a product＇s life cycle is the first step on the search of sustainable development. The life cycle assessment （LCA） is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the ＂returns＂ to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks： glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging.
