Biodiversity,natural resource accounting and ecological monitoring

The role that natural resource accounting and ecological monitoring can play in conserving biological diversity is discussed. There exists a widespread view that modifications to national income accounting procedures are crucial to the pursuit of sustainability and particularly the protection of biodiversity. However, we argue that the availability of biologically-adjusted national income figures would not, of itself, be likely to contribute significantly to the protection of biological resources. The conservation of biodiversity requires, among other things, a significantly improved understanding of the nature of environmental changes arising from imposed management regimes and the effects that these changes have on the persistence of biodiversity. On this basis, and in the context of sustainable development, we suggest that ecological monitoring should take priority over the generation of economic data.In many regions of the world sufficient ecological knowledge is available to design and implement integrated monitoring networks that can be used to track the status of many components of biodiversity and inform decisions taken over their management. We outline how this might be undertaken using a hierarchical and prioritised approach aimed, pragmatically, in the first instance at helping to preserve those ecosystems, communities and species which are perceived to be most threatened. Some emphasis is given to the Australian situation because it is the only rich megadiversity nation and it is at the forefront of the development of scientific techniques that can be used to help design soundly-based and cost-effective monitoring programs.We acknowledge the useful comments of two referees, and claim exclusive property rights in remaining errors.     

Determinants of Monitoring Capabilities in International Franchising: Foodservice Firms within East Asia

This paper undertakes an exploratory study on determining capabilities of international franchising within East Asia. There is a need to develop a deeper understanding in franchising within East Asia as much of the franchising literature is based on the U.S. experience. Findings from this paper indicate that international franchisors use a combination of mechanisms to prevent franchisee opportunism in East Asia. They include ex-ante bonds, performance schedules and formal controls in brand management. However, the effectiveness of these mechanisms depend on the capabilities of the franchisor to negotiate a high initial franchise fee, select the right franchisee and make adaptation but still maintain brand integrity.     

云南偏远民族山区农村公共文化服务体系建设的调查与思考——以开远市碑格乡为例

农村公共文化服务体系建设是满足农村群众文化需求、保障其基本文化权益的重要途径。由于地理、历史、经济等原因,偏远少数民族山区成为云南农村公共文化服务体系建设＂遗漏的角落＂和瓶颈。开远市碑格乡的实地调查表明,云南偏远民族山区农村公共文化服务体系建设存在着供需矛盾突出、建设成本高、补助标准低、缺乏地域民族特色、文化工作经费被挪用、文化设施管护不够、利用率低、农村文化人才严重缺乏等问题。

Developing an integrated approach for the strategic monitoring of regional spatial plans

Monitoring is a challenging and fundamental issue within planning processes, yet there is little understanding as to whether plans achieved their goals in guaranteeing sustainable development on a territorial level. Follow-up of spatial planning is rather difficult due to insufficient methodologies, deficiencies in plans’ contents and resource limitations. The main goal of this research is to develop and test a conceptual framework to support the development of effective indicator based regional spatial plans’ (RSPs) monitoring systems. The conceptual framework includes indicators with distinct purposes and has the following features: (i) it establishes links between RSPs, their strategic environmental assessment and monitoring indicators; (ii) it incorporates the contribution of other existing monitoring systems in the regions; and (iii) it defines specific indicator selection criteria. In order to inform the development of the conceptual framework we: (i) review international practice of RSP monitoring; (ii) analyse the features of current Portuguese RSPs; (iii) test the conceptual framework using the RSP and the regional sustainability indicator system of the Algarve region (Portugal) as a case study. Two types of indicators were developed - output/implementation and results/effects - for improving the identification of cause-effect relationships between RSP implementation and associated territorial effects; although this is a continuing challenge, given the strategic nature of RSPs. The usefulness of the conceptual framework was demonstrated in the definition of monitoring indicators for the Algarve's RSP, as well as in the integration of an existing regional sustainability monitoring system.
