A decision model for selecting sustainable drinking water supply and greywater reuse systems for developing communities with a case study in Cimahi, Indonesia

Capacity Factor Analysis is a decision support system for selection of appropriate technologies for municipal sanitation services in developing communities. Developing communities are those that lack the capability to provide adequate access to one or more essential services, such as water and sanitation, to their residents. This research developed two elements of Capacity Factor Analysis: a capacity factor based classification for technologies using requirements analysis, and a matching policy for choosing technology options. First, requirements analysis is used to develop a ranking for drinking water supply and greywater reuse technologies. Second, using the Capacity Factor Analysis approach, a matching policy is developed to guide decision makers in selecting the appropriate drinking water supply or greywater reuse technology option for their community. Finally, a scenario-based informal hypothesis test is developed to assist in qualitative model validation through case study. Capacity Factor Analysis is then applied in Cimahi Indonesia as a form of validation. The completed Capacity Factor Analysis model will allow developing communities to select drinking water supply and greywater reuse systems that are safe, affordable, able to be built and managed by the community using local resources, and are amenable to expansion as the community's management capacity increases.     

Action-Oriented Support for Occupational Safety and Health Programs in Some Developing Countries in Asia

Action-oriented support programs have been increasingly playing vital roles in promoting safety and health in developing countries in Asia. This paper studied achievements of 3 action-oriented support programs: the WISE program for small enterprises, the WIND program for farmers, and the POSITIVE program for workers and trade unions. Special attention was paid to how the programs have strengthened local efforts for sustainable actions in safety and health improvements. The results showed that there were significant achievements in action-oriented support programs in the region, including a large number of improvement examples, integration into government policies, and network support through employers’ and workers’ organizations. Participatory, action-oriented training tools such as action-checklists, local good example photos, and group work methods played key roles in the effective implementation of the programs. It was of note that there were a number of local efforts to extend the coverage of action-oriented support even to hard-to-reach workers such as home-based workers, rural workers, and ethnic minorities. The efforts included the equal participation in the training by female and male farmers, shortened and weekend training programs, photo sheets showing local good examples, and reasonable fee collection for better sustainability. In conclusion, action-oriented support programs provided local people with concrete means to promote safety and health improvements. The successful programs commonly focused on local initiatives and were built on local wisdom and resources.     

Constraints to implementation of sustainability indicator systems in five Asian cities

Contemporary studies on sustainability indicator systems (SISs) typically focus on the technical advancement of indicator construction, on qualitative impacts of indicator programmes and on impacts on governance, decision-making and sustainability as a social construct. Yet, their implementation so far has rarely been addressed, even though monitoring and the use of indicator results fall far behind the number of SISs developed. This study aims at the identification of requirements for the development of and constraints to the implementation of SISs in five Asian cities of developing countries. Interviews with local key actors are held, and a qualitative content analysis is carried out. Findings include evidence on the degree of indicator implementation in the case study cities, a hexagonal model for the classification of requirements and constraints, as well as general conclusions for barriers to the use of SISs.     

Greenhouse gas mitigation in developing countries through technology transfer?: a survey of empirical evidence

While greenhouse gas (GHG) emissions are projected to rise primarily in the developing countries, the potential for developing new GHG mitigation technologies exists primarily in the industrialized countries. It is thus important, not only for predictions about future emission paths but also for climate change mitigation policies, to understand how the international diffusion of such technologies takes place and how it affects the energy infrastructure and GHG emissions in developing countries. This paper provides an overview of the channels through which these technologies diffuse and focuses on the empirical evidence pertaining to the effects these technologies have on GHG emissions in developing countries.

Sustainable development as a framework for developing country participation in international climate change policies

The paper presents a number of ideas on how climate change policy implementation in developing countries can be supported by alternative international cooperation mechanisms that are based on stakeholder interests and policy priorities including broader economic and social development issues. It includes a brief review of current development policies, technological research and promotion efforts, and climate change that demonstrates that mutual policy initiatives undertaken by governments and the private sector actually have major positive impacts on climate change without being initiated by this global policy concern. Furthermore a number of examples are given on how future development objectives in Brazil, China, and India jointly can support economic and social goals and global climate change concerns if these goals are taken into consideration and supported by international cooperative mechanisms. The paper proposes international cooperative mechanisms that can support the implementation of integrated development and climate change policies. The mechanisms include an international sustainable development (SD) and Climate Finance Mechanism (SDCFM), technology development and transition programmes, technology standards, and other measures.

产业关联水平对碳排放演化的影响机理及效应研究——基于欧盟27国投入产出数据的实证分析

碳排放逐步升高是以工业化为特征的区域经济崛起的必然结果。论文的理论研究说明,产业关联水平反映了区域发展过程中产业多样化和分工细化的程度,相较于产业结构,产业关联水平对区域经济发展水平的指示意义更深刻。那么,产业关联水平对碳排放的影响特征及其趋势将更接近于碳排放在经济发展驱动下的演进规律。因此,论文采用欧盟27国投入产出数据,在测算不同类型制造业和服务业的产业关联水平的基础上,确定不同类型制造业所对应的特征服务业类型,进而应用经济计量学工具对制造业与服务业产业关联度对碳排放的影响进行实证分析,结果显示：第一,作为发达经济体,欧盟的制造业与服务业整体间产业关联度对碳排放具有显著负效应;第二,低端、中端和高端制造业与各自对应特征服务业类型间产业关联度对碳排放的影响均较为显著,其强度呈现随制造业水平升级而先上升、后下降的趋势;第三,高端制造业与生产性、分配性服务业间产业关联度的提高是实现区域碳排放达到峰值并逐步下降的重要动力,而中端制造业与其对应特征服务业关联度提升对碳排放的正向效应将高于低端制造业主导时期。因此,结合发达经济体的发展经验可以发现,碳排放的演化具有规律性特征,而以产业关联度入手的分析能够提供操作性更强的参考。目前,中国应在推动产业结构升级结构的过程中,大力提升生产性服务业的发展水平及其与制造业的关联水平,并采取积极措施降低交通运输业等分配性服务业的能耗强度。
