Local Agenda 21 and Barriers to Sustainability at the Local Government Level in Victoria,Australia

At the 1992 Rio 'Earth Summit', Australia joined other nations in committing to processes leading to the formulation of 'Local Agenda 21s' (LA21s) by 1996. Subsequently, in the latter year, Whittaker carried out a national survey of local government authorities to evaluate what progress had been made. Whittaker's conclusion was that progress in Australia had been slow, but ten 'leading-edge' Victorian councils were identified through a self-reporting process. In this paper we discuss the concept of LA21, analyse in closer detail the 'progress' that has been made in the ten Victorian councils, and discuss some of the broader forces that, we argue, have made LA21 formulation increasingly difficult, particularly in the state of Victoria in the recent past.

From impacts assessment to adaptation priorities: the shaping of adaptation policy

Abstract

Under the United Nations Framework Convention on Climate Change (UNFCCC), adaptation has recently gained importance, yet adaptation is much less developed than mitigation as a policy response. Adaptation research has been used to help answer to related but distinct questions. (1) To what extent can adaptation reduce impacts of climate change? (2) What adaptation policies are needed, and how can they best be developed, applied and funded? For the first question, the emphasis is on the aggregate value of adaptation so that this may be used to estimate net impacts. An important purpose is to compare net impacts with the costs of mitigation. In the second question, the emphasis is on the design and prioritisation of adaptation policies and measures. While both types of research are conducted in a policy context, they differ in their character, application, and purpose. The impacts/mitigation research is orientated towards the physical and biological science of impacts and adaptation, while research on the ways and means of adaptation is focussed on the social and economic determinants of vulnerability in a development context. The main purpose of this paper is to demonstrate how the national adaptation studies carried under the UNFCCC are broadening the paradigm, from the impacts/mitigation to vulnerability/adaptation. For this to occur, new policy research is needed. While the broad new directions of both research and policy can now be discerned, there remain a number of outstanding issues to be considered.     

Socioeconomics effects on global hotspots of common debris items on land and the seafloor

Pollution of coastal environments by anthropogenic debris is a global problem that is increasingly in the public eye. We evaluated the influence of socioeconomic and geographic factors on common debris items at a global scale. We compared debris density and socioeconomic drivers of the ten most common items reported on land and the seafloor, analyzing data from 22,508 land-based and 7,290 seafloor clean-ups and surveys across 116 and 118 countries, respectively. We found debris hotspots for different items span numerous countries across all continents. This demonstrates that the debris problem is global and heterogeneous, pointing to the transboundary nature of the issue and necessitating sub-national approaches to implementing effective solutions. Food and beverage packaging items, predominantly made from single-use plastics, accounted for much of the debris. Hotspots of individual debris items were differentially driven by socioeconomic factors. In general, total debris counts increased with the value of infrastructure, and decreased with national wealth. Highly polluted sites occurred in high-infrastructure, low-wealth locations such as Athens, Greece; Tunis, Tunisia and Lima, Peru. Based on these findings, we identify specific opportunities for policy makers and citizens alike to focus efforts aimed at reducing debris entering the environment.     

中国气候变化南南合作对《巴黎协定》后适应谈判的影响

适应气候变化是发展中国家的重要谈判议题。《联合国气候变化框架公约》2015年达成《巴黎协定》后如何落实适应议题实施细则成为关注焦点。发达国家以温室气体排放总量大为理由,施压中国等发展中大国出资全球适应气候变化行动;发展中国家内部对适应气候变化受害方和出资方的划分存在较大分歧,造成适应议题下发展中国家集团难以形成合力,《巴黎协定》实施细则谈判进展缓慢。中国气候变化南南合作作为中国与其他发展中国家之间重要的气候变化领域合作形式,能否通过寻找发展中国家契合点,依据合理机制,对适应谈判发挥一定作用,须及早进行利弊分析及顶层设计。文章通过分析美欧日对外援助的机制、梳理非洲小岛国等主要发展中国家集团在应对气候变化不利影响方面的需求、总结以往中国适应项目对外援助情况的基础上,提出了今后中国气候变化南南合作与适应谈判中需要注意的问题,包括区分适应援助和减缓援助、避免中国气候变化南南合作的属性被误读等问题,为争取广阔外交利益、合理构建南南合作机制提供政策建议。     

Political ecology in the key of policy: From chains of explanation to webs of relation

Political ecology (PE) is rooted in a combination of critical perspectives and the hard won insights distilled from field work. The theoretical base of political ecology was joined, by Piers Blaikie and others, to an unflinching commitment to empirical observation of biophysical and socio-economic phenomena in place. To this already ambitious mix was added a practical intent to contribute to material as well as social change: a practical political ecology of alternative development ran beneath the surface of much of this work. For many this led to serious encounters with policy and the machinery of policy research institutions. While seemingly contradictory with the critical tenets of political ecology, Blaikie’s pursuit of this pathway led beyond the ivory tower to Political Ecology in the Key of Policy, initially to inform national and international policy and eventually expanding - through the work of second-generation PE - to address internal policy in social movements and alternative development networks. Among recent variations on political ecology that have built partly on the work of Blaikie, Feminist Political Ecology (FPE) expands PE to address women as a group, and gender as a category. FPE and post-structural PE are based on multiple actors with complex and overlapping identities, affinities and interests. An emergent wave of political ecology joins FPE, post-structural theory, and complexity science, to address theory, policy and practice in alternatives to sustainable development. It combines a radical empiricism and situated science, with feminist post-structural theories of multiple identity and “location”, and alternative development paradigms. This approach honors the legacy of Piers Blaikie and other PE founders yet incorporates the insights and political projects of feminism, post-structural critique and autonomous or alternative development movements.

Exploring the health context: A qualitative study of local heat and climate change adaptation in Japan

Extreme temperature events and global climatic changes may put human health at risk. Urban centers are particularly vulnerable to adverse effects of climate change. Japan is a densely populated and highly urbanized island frequently exposed to natural hazards and heat episodes. Japanese governments and practitioners design heat adaptation strategies to protect health and reduce risks. Are these strategies implemented at the local level? How do policymakers and researchers perceive heat and climate change adaptation measures? How are these strategies evaluated? In short: what is happening in Japan “on the ground”? This critical review briefly outlines heat adaptation solutions and challenges from three Japanese prefectures. It draws attention to implementation and evaluation barriers, and highlights creative approaches to adaptation, such as involving civil society volunteers.     

Land-use and sustainability under intersecting global change and domestic policy scenarios: Trajectories for Australia to 2050

Understanding potential future influence of environmental, economic, and social drivers on land-use and sustainability is critical for guiding strategic decisions that can help nations adapt to change, anticipate opportunities, and cope with surprises. Using the Land-Use Trade-Offs (LUTO) model, we undertook a comprehensive, detailed, integrated, and quantitative scenario analysis of land-use and sustainability for Australia’s agricultural land from 2013–2050, under interacting global change and domestic policies, and considering key uncertainties. We assessed land use competition between multiple land-uses and assessed the sustainability of economic returns and ecosystem services at high spatial (1.1 km grid cells) and temporal (annual) resolution. We found substantial potential for land-use transition from agriculture to carbon plantings, environmental plantings, and biofuels cropping under certain scenarios, with impacts on the sustainability of economic returns and ecosystem services including food/fibre production, emissions abatement, water resource use, biodiversity services, and energy production. However, the type, magnitude, timing, and location of land-use responses and their impacts were highly dependent on scenario parameter assumptions including global outlook and emissions abatement effort, domestic land-use policy settings, land-use change adoption behaviour, productivity growth, and capacity constraints. With strong global abatement incentives complemented by biodiversity-focussed domestic land-use policy, land-use responses can substantially increase and diversify economic returns to land and produce a much wider range of ecosystem services such as emissions abatement, biodiversity, and energy, without major impacts on agricultural production. However, better governance is needed for managing potentially significant water resource impacts. The results have wide-ranging implications for land-use and sustainability policy and governance at global and domestic scales and can inform strategic thinking and decision-making about land-use and sustainability in Australia. A comprehensive and freely available 26 GB data pack (http://doi.org/10.4225/08/5604A2E8A00CC) provides a unique resource for further research. As similarly nuanced transformational change is also possible elsewhere, our template for comprehensive, integrated, quantitative, and high resolution scenario analysis can support other nations in strategic thinking and decision-making to prepare for an uncertain future.     

Closing the governance gaps in the water-energy-food nexus: Insights from integrative governance

The water-energy-food nexus has become a popular concept in environmental change research and policy debates. Proponents suggest that a nexus approach promotes policy coherence through identifying optimal policy mixes and governance arrangements across the water, energy and food sectors. Although the nexus literature identifies some barriers to achieving coherence it does not clearly explain why the barriers are present, what influences them, and how they can be acted upon. These gaps disconnect the nexus literature from the governance processes it ultimately seeks to influence. This paper examines how the integrative environmental governance literature can help to close these gaps. It extracts insights from seven streams of research literature and discusses their relevance for the nexus literature. We argue that connecting the nexus to decision-making processes requires: i) rethinking the boundaries of nexus analysis vis-à-vis other sectors and levels; ii) elaboration of shared principles that can guide decision-making towards policy coherence − or an appropriate form of fragmentation − in different contexts; iii) viewing policy coherence as a continuous process of changing values and perception rather than as an outcome.
