Scenarios and sustainability: tools for alleviating the gap between municipal means and responsibilities in adaptation planning

Adaptation to climate change often involves long-time frames and uncertainties over the consequences of chosen adaptation measures. In this study, two tools designed for assisting local decision-makers in adaptation planning were tested: socio-economic scenarios and sustainability analysis. The objective was to study whether these tools could be of practical relevance to Swedish municipalities and facilitate local-level climate change adaptation. We found that the municipal planners who participated in the testing generally considered the tools useful and of high relevance, but that more time was needed to use the tools than was provided during the test process.

Does remediation save lives? - on the cost of cleaning up arsenic-contaminated sites in Sweden.

Sweden has only just begun remediation of its many contaminated sites, a process that will cost an estimated SEK 60,000 million (USD 9100 million). Although the risk assessment method, carried out by the Swedish EPA, is driven by health effects, it does not consider actual exposure. Instead, the sites are assessed based on divergence from guideline values. This paper uses an environmental medicine approach that takes exposure into account to analyse how cancer risks on and near arsenic-contaminated sites are implicitly valued in the remediation process. The results show that the level of ambition is high. At 23 contaminated sites, the cost per life saved varies from SEK 287 million to SEK 1,835,000 million, despite conservative calculations that in fact probably underestimate the costs. It is concluded that if environmental health risks are to be reduced, there are probably other areas where economic resources can be used more cost-effectively.

Incentives and outcomes: Evaluation of a Swedish environmental subsidy programme

Abstract This paper empirically evaluates a Swedish government subsidy to environmental sustainability, the Local Investment Programme (LIP). During the programme period, 1998 – 2002, more than 670 million was granted to 1814 different municipal projects, making it the largest Swedish subsidization to ecological sustainability to date. For the 682 projects evaluated here, it was found that the projects were rewarded smaller subsidies than granted. To explain the gap between granted and rewarded subsidies, the gap was decomposed into a quantity effect, depending on the quantified environmental and employment outcomes of the projects, and a price effect, depending on the governments valuation of these outcomes. Whereas no statistically significant quantity effect was found, there was a large statistically significant price effect, indicating that the government paid the municipalities less than promised in the granting decision.

Can we buy time? Evaluation of the Swedish government's grant to remediation of contaminated sites

The major aim of this paper is to analyze how government funding affects the pace of progress in four states of the remediation process of contaminated sites, from basic risk classification to cleanup. We introduce a methodological framework that takes into account the unobserved site-heterogeneity and simultaneously models duration in the different states. The results show that although site-heterogeneity contributes to make remediation a slow process, the third state, from the elaborate risk classification to the cleanup start, is a particular bottleneck. Even if government funding can speed up the process at this state, the effect is minuscule compared to the amounts of funding required. Thus, there is a need for policy to also focus on other barriers to remediation.

Itsy Bitsy Spider…: Infants React with Increased Arousal to Spiders and Snakes

Attention biases have been reported for ancestral threats like spiders and snakes in infants, children, and adults. However, it is currently unclear whether these stimuli induce increased physiological arousal in infants. Here, 6-month-old infants were presented with pictures of spiders and flowers (Study 1, within-subjects), or snakes and fish (Study 1, within-subjects; Study 2, between-subjects). Infants’ pupillary responses linked to activation of the noradrenergic system were measured. Infants reacted with increased pupillary dilation indicating arousal to spiders and snakes compared with flowers and fish. Results support the notion of an evolved preparedness for developing fear of these ancestral threats.

Making climate policy efficient: implementing a model for environmental policy efficiency

We propose a framework for studies of efficiency in environmental policies in the form of a conceptual policy cycle. The policy cycle’s six major elements are goal-setting, choice of policy instruments, enforcement, changes in behaviour of public and private agents, effects of policy measures and, finally, evaluation. Through iterating the policy cycle (or parts of it), efficiency in environmental policies can be improved. We apply the policy cycle to climate policies, both mitigation and adaptation, and identify important areas for future research.
