Sound and Fury Signifying Nothing: Using Geoinformatics to Inform Resource Policy in the Gulf of California,Mexico

In this issue of Environmental Management, Glenn and others posit that a previous study had analytical and interpretive errors in analysis of shrimp fishing in the Upper Gulf of California, Mexico. Unfortunately, much of their evidence is too indirect and of insufficient scale to address the central question of salinity in the Upper Gulf. Also, many of their suppositions did not include direct interviews with local officials or a robust understanding of remote sensing literature. This response to their rebuttal presents a set of figures and analysis demonstrating that the Colorado River flows into a closed evaporative basin known as the Laguna Salada and thus cannot flow into the Gulf of California. Readers are asked to examine the images and interpret their meaning for themselves.     

Examining bushfire policy in action: Preparedness and behaviour in the 2009 Black Saturday fires

An important part of reducing the risk of disaster is the preparedness of the people at risk. Australian bushfire authorities have policies and publicity about what households should do to be prepared – which include knowledge about fire risk, awareness of one’s own risk, taking specific steps to reduce risk including having an emergency plan. Yet, there is sparse empirical evidence about the link between preparedness and actual behaviour in the face of a major disaster.The authors had an opportunity to examine the circumstances surrounding the 172 civilian fatalities which occurred in the 2009 Victorian ‘Black Saturday’ bushfires, through the examination of a detailed fatality dataset compiled by the Victorian Bushfires Royal Commission. This dataset allows detailed examination of Victorian bushfire safety policy (‘Stay or go’) in action on a day of extreme fire danger: from preparedness (both before and on the day of the fire) to behaviour on the day of the fire itself.This analysis presents three overarching findings. First, some aspects of ‘Stay or go’ appear to be supported: being well-prepared to evacuate remains the safest option in a bushfire; sheltering passively is very dangerous. Second, successful implementation of ‘Stay or go’ depends on a multitude of factors, which can challenge even the most capable householders. Third, events like Black Saturday challenge the ‘Stay or go’ approach, and indicate the need for a different approach on extreme fire danger days. We conclude by reflecting on the findings from this research in terms of the most recent changes to bushfire policy in Victoria.     

Public acceptability towards environmental policy measures: Value-matching appeals

People’s acceptability of environmental policy measures is vital for a successful implementation. Identifying how information concerning radical policy measures can be improved may increase support and generate more positive attitudes towards the policy. The effect of tailored information on acceptability towards implementing a proposed congestion charge was investigated by matching ecocentric arguments to biospherically value-oriented participants, and anthropocentric arguments to those who endorsed egoistic values. 627 respondents living in two small Swedish cities participated via a web-based survey. The results show that the single arguments (anthropocentric or ecocentric appeals) were evaluated more favourably than the combination of arguments (including both anthropocentric and ecocentric appeals). Strong biospheric and strong egoistic values were associated with positive and negative evaluations of the policy proposal, respectively. Finally, while respondents who endorsed egoistic values tended to be more positive towards the proposal after reading anthropocentric arguments (value match) than after reading pro-environmental arguments (value mismatch), the opposite effect was observed for respondents who did not endorse egoistic values. Our results suggest that tailoring information with regard to people’s values would be effective in promoting positive attitudes towards important policy measures.     

环境管制政策的局限性与变革--自愿性环境政策的兴起

我国虽然基本上避免了环境质量急剧恶化的局面。但是现行环境政策并没有从根本上遏制环境状况不断恶化的趋势，我国环境政策的效率亟待摄高。究其原因，我国环境政策以行政直控的管制政策为主。具有强烈的行政管理色彩，使得政府和企业的博弈长期锁定在非合作状态。要摆脱这种困境，必须引入第三方激励、监督机制。促使双方的博弈转变为合作博弈。20世纪90年代中期自愿性环境政策的渐渐兴起，是企业和公众在产品市场上互相影响的结果。而政府起到引导激励、信号传递作用。文章从博弈论的角度对此进行了分析，自愿性环境政策缓解了环境管制成本与效果冲突的困境，是未来环境政策的一个重要的方向。

Using Citizen Science Programs to Identify Host Resistance in Pest‐Invaded Forests

Abstract: Threats to native forests from non‐native insects and pathogens (pests) are generally addressed with methods such as quarantine, eradication, biological control, and development of resistant stock through hybridization and breeding. In conjunction with such efforts, it may be useful to have citizen scientists locate rare surviving trees that may be naturally pest resistant or tolerant. The degree of resistance of individual trees identified in this way can be tested under controlled conditions, and the most resistant individuals can be integrated into plant breeding programs aimed at developing pest‐resistant native stock. Involving citizen scientists in programs aimed at identifying rare trees that survive colonization by pests provides a low‐cost means of maximizing search efforts across wide geographic regions and may provide an effective supplement to existing management approaches.     

A Conceptual Analysis of the Application of Tradable Permits to Biodiversity Conservation

Abstract: Tradable permits have been applied in many areas of environmental policy and may be a response to increasing calls for flexible conservation instruments that successfully conserve biodiversity while allowing for economic development. The idea behind applying tradable permits to conservation is that developers wishing to turn land to economic purposes, thereby destroying valuable habitat, may only do so if they submit a permit to the conservation agency showing that habitat of at least the equivalent ecological value is restored elsewhere. The developer himself does not need to carry out the restoration, but may buy a permit from a third party, thus allowing a market to emerge. Nevertheless, the application of tradable permits to biodiversity conservation is a complex issue because destroyed and restored habitats are likely to differ. There may be various trade‐offs between the ecological requirements that destroyed and restored habitats be as similar as possible, and the need for a certain level of market activity to have a functioning trading system. The success of tradable permits as an instrument for reconciling the conflicts between economic development and conservation depends on the existence of certain economic, institutional, and ecological preconditions, for example, a functioning institutional framework, sufficient expert knowledge, and adequate monitoring and enforcement mechanisms.     

Historical assessment of Chinese and Japanese flood management policies and implications for managing future floods

Floods are among the world's most devastating natural disasters, causing immense damage and accounting for a large number of deaths world-wide. Good flood management policies play an extremely important role in preventing floods. It is well known that China has more than 5000 years of experience in flood management policy beginning with the reign of DaYu and Gun. Although culturally related, Japanese flood management developed differently from that of China. Under rapid development of civil engineering technology, flood management was achieved primarily through the construction of dams, levees and other structures. These structures were never adequate to stop all floods, and recent climate change driven extreme events are ever more frequently overwhelming such infrastructure. It is important to take a historical perspective of Japanese and Chinese flood management in order to better manage increasingly frequent extreme events and climate change. We present insights taken from an historical overview of Japanese and Chinese flood management policies in order to guide future flood risk management policy.
