Preserving coastal natural character: Court interpretations of a long‐standing New Zealand policy goal

New Zealand's policy goal to preserve coastal natural character was first incorporated into planning legislation in 1973 and protected area legislation in 1977. An evaluation of 100 relevant Resource Management Act Court decisions determined the Courts' interpretations of this policy goal. The Courts have repeatedly found that natural character is of nature (not culture), including natural elements, patterns, and processes. There is a continuum of naturalness from pristine indigenous ecosystems to the urban environment. A 2014 Supreme Court decision has upheld the use of environmental bottom lines for natural character and the importance of protection as part of sustainable management.     

Ideas out of context and the contextualization of ideas: The transference of Jane Jacobs to São Paulo

The mobility and contextualization of urban policies between localities have received significant attention in recent literature. A number of mechanisms have been identified, including “best practices,” “policy tourism,” multinational firms, and conferences have been identified. This article identifies a new mechanism: the translation and publication of seminal theses into additional languages. Using citations analysis and interviews in São Paulo, this mechanism is confirmed as an additional mode of transference and identified as being responsible for the growth in interest in Jane Jacobs in São Paulo. However, this article finds that despite the increase in accessibility to her ideals, her emphasis on contextuality was overlooked in that case. This, in turn, calls attention to larger issues of the use of so-called ‘universally-good’ examples of urbanism.     

Thirteen plus one: a comparison of global climate policy architectures

We critically review the Kyoto Protocol and thirteen alternative policy architectures for addressing the threat of global climate change. We employ six criteria to evaluate the policy proposals: environmental outcome, dynamic efficiency, cost-effectiveness, equity, flexibility in the presence of new information, and incentives for participation and compliance. The Kyoto Protocol does not fare well on a number of criteria, but none of the alternative proposals fare well along all six dimensions. We identify several major themes among the alternative proposals: Kyoto is “too little, too fast”; developing countries (DCs) should play a more substantial role and receive incentives to participate; implementation should focus on market-based approaches, especially those with price mechanisms; and participation and compliance incentives are inadequately addressed by most proposals. Our investigation reveals tensions among several of the evaluative criteria, such as between environmental outcome and efficiency, and between cost-effectiveness and incentives for participation and compliance.     

Action targets: a new approach to international greenhouse gas controls

Abstract

This article introduces and explores a new form of international commitment to limit greenhouse gas (GHG) emissions, called an action target. Action targets differ from other forms of targets, such as the Kyoto Protocol's fixed targets, in that they define a quantity of GHG abatement to be achieved, rather than a future emission level to be reached. This article explains the basic mechanics of how action targets might operate, and analyses the approach across a range of criteria, including uncertainty management and contributions to sustainable development in non-Annex I (developing) countries. The analysis suggests that action targets might improve the prospects of widening and deepening developing country participation in the international climate regime.     

The Implementation Effects of a Nationwide Sloping Farmland Soil Erosion Control Project in China

To understand implementation of a nationwide sloping farmland soil erosion comprehensive control project during China’s 12^th Five-Year Plan we used data collection and expert consultation. We selected 24 indexes across three aspects including project management, engineering construction and implementation benefit and used AHP-grey correlation analysis methods. We found that the scores for engineering construction were greater than 0.65 in most of the provinces, autonomous regions and municipalities. These scores are high and scores for project management and implementation benefit are between 0.45-0.65; however, overall scores are low. The comprehensive evaluation results are normally distributed. The composite scores for Sichuan, Yunnan and Guizhou are 0.71, 0.68 and 0.68 respectively, indicating that the implementation effects are good. The scores for Jilin and Liaoning are 0.38 and 0.42 respectively, indicating that the implementation effects need improvement. Scores for other provinces are between 0.45-0.65 and the effects are medium. The evaluation results show certain zonal rules spatially and the implementation effect in karst regions of Southwest China is the highest, followed by the purple soil region in Southwest China, Loess Plateau region of Northwest China, earth-rock mountain region of North China and red soil hilly region of South China. The implementation effect in the black soil region of Northeast China suggests that improvement is needed in this region.     

Interannual climate variation,land type and village livelihood effects on fires in Kalimantan,Indonesia

The increasing extent and frequency of fires globally requires nuanced understanding of the drivers of large-scale events for improved prevention and mitigation. Yet, the drivers of fires are often poorly understood by various stakeholders in spatially expansive and temporally dynamic landscapes. Further, perceptions about the main cause of fires vary amongst stakeholders, which amplify ongoing challenges from policies being implemented inconsistently across different governance levels. Here, we develop a spatially and temporally-explicit typology of fire prevalence across Kalimantan, Indonesia, a region with significant contribution to global greenhouse gas emissions. Based on livelihood information and data on climate, soil type and forest degradation status, we find that in intact forest the density of fires in villages that largely coincide with oil palm concessions was twice as high as in villages outside the concessions across all years. Fires occurring in degraded land on mineral soil across all years were also most prevalent in villages with industrial plantations (oil palm or timber). On the other hand, in degraded peatland, where fires are most intense during dry years induced by the El Niño episodes, occurrence rates were high regardless of village primary livelihoods. Based on these findings we recommend two key priorities for fire mitigation going forward for policy across different governance levels in Kalimantan: degraded peatland as the priority area and industrial plantations as the priority sector. Our study suggests a fire prevention and mitigation approach, which accounts for climate, land type and village livelihood, has the potential to deliver more effective means of management.     

Fisheries mismanagement

We analysed the extent to which European politicians have adhered to scientific recommendations on annual total allowable catches (TACs) from 1987 to 2011, covering most of the period of the Common Fisheries Policy (CFP). For the 11 stocks examined, TACs were set higher than scientific recommendations in 68% of decisions. Politically-adjusted TACs averaged 33% above scientifically recommended levels. There was no evidence that the 2002 reform of the CFP improved decision-making, as was claimed at the time. We modelled the effects of such politically-driven decision-making on stock sustainability. Our results suggest that political adjustment of scientific recommendations dramatically increases the probability of a stock collapsing within 40 years.In 2012 European fisheries policy will undergo a once-a-decade reform. Ten years ago radical reforms were promised but the changes failed to improve sustainability. It is likely that the 2012 reform will be similarly ineffective unless decision-making is changed so that catch allocations are based on science rather than politics.

Geography in Alaska: Holding the Standards High

Abstract

In 1992, the State of Alaska Department of Education embarked on a standards-writing process as part of its Alaska 2000 reform effort. Supported by a Frameworks Grant from the U.S. Department of Education, standards were written in geography, government/civics, and history during 1993 and 1994. This article highlights an extensive statewide public consensus process used to generate the Alaska 2000 Geography Standards, which were modeled after Geography for Life: National Geographic Standards 1994.
