Planning for a sustainable Oslo: the challenge of turning urban theory into practice

Many cities today face challenges related to urban growth. This is also the case in Oslo, currently one of the fastest growing capitals in Europe. In order to prepare for the population growth, a new municipal master plan has been prepared. In this, sustainable development is a prominent concept, and the urban district is going to be densified as part of the strategy. This paper examines some obstacles of turning planning theory into practice. There is a lack of coherence between municipal goals and the actual outcome. The analysis indicates that the official strategy is not able to cater for social sustainability partly due to institutional constraints. Moreover, there is no concise understanding of what sustainability means, which in turn hampers the ability to operationalise the concept in urban planning.     

Risk and Responsibility in Public Engagement by Climate Scientists: Reconsidering Advocacy During the Trump Era

The election as US President of Donald J Trump, who denies the scientific consensus on climate change, raises questions about the role of scientists in public discourse. How far should scientists wade into the waters of advocacy before risking their credibility of fair arbiters of knowledge? The new study by Kotcher, Myers, Vraga, Stenhouse, and Maibach [2017. Does engagement in advocacy hurt the credibility of scientists? Results from a randomized national survey experiment. Environmental Communication. doi:10.1080/17524032.2016.1275736] is a reminder that scientists are among the most trusted people in public life and have some freedom to engage publicly without harming their reputation. However, with the power to influence public debate comes the responsibility to carefully consider the impact of statements and actions. This commentary discusses the challenges facing scientists at a time of great potential for public engagement, and for a gap between perceived and actual intent of public statements.     

Facebook and Twitter,communication and shelter,and the 2011 Tuscaloosa tornado

This paper represents one of the first attempts to analyse the many ways in which Facebook and Twitter were used during a tornado disaster. Comparisons between five randomly selected campus samples and a city of Tuscaloosa, Alabama, sample revealed that campus samples used Facebook and Twitter significantly more both before and after the tornado, but Facebook usage was not significantly different after the event. Furthermore, differences in social media usage and other forms of communication before the tornado were found for age, education, and years lived in Tuscaloosa. Generally, age and education were inversely proportionate to social media usage. Influences on shelter‐seeking actions varied between social media users and three random samples of non‐social media users; however, it appears that social media respondents were likely to be using a smartphone simultaneously to access warning polygon information, to receive text message alerts, and to listen or respond to environmental cues.     

Young adult conservation jobs and worker health

Decades of research studies demonstrate links between healthy environment, healthy lifestyles, and healthy people. This study evaluated the correlations between young adult conservation workers' perceived stress, personal effectiveness, and nature experience using quantitative and qualitative social science methods. The study cohort numbered nearly 300 individuals serving on small crews for an entire year, and were dispersed across Washington State (USA) to participate in conservation projects in rural to urban landscapes. Pre- and post-test surveys, using validated measures of perceived stress, health dimensions, and personal resiliency, were further informed by mid-year, field-based interviews. Overall, the young adults expressed fatigue with the physical work but were quite healthy when compared to national benchmarks. They indicated a reduction in perceived stress, and indicated social function influences based on the conservation work. Conclusions address the importance and implications of expanding this work opportunity to a more diverse cohort and future research needs.     

Structural factors influencing conservation decision-making: a case of species prioritisation in Australia

Prioritisation methods have been adopted for >20 years to inform resource allocation in species conservation. The academic literature on prioritisation focuses on technical matters, with little attention to the socio-political factors affecting the uptake of priorities. We investigated the policy instruments employed to promote uptake, and the structural factors affecting the uptake of priorities, using as our case study a species prioritisation method adopted by the Queensland Government (Australia). We interviewed 79 key informants and analysed policy documents and plans. The Queensland Government relied on ‘information delivery’ as a policy instrument to foster uptake. We identified communication channels to assist ‘information delivery’ between Government and intended users, but also found that several structural factors limited their use: fragmentation of policies, the relative strength of alternative priorities and centralisation of power in decision-making. We discuss the results in relation to other conservation planning initiatives and suggest how structural barriers can be addressed.     

How planners and stakeholders learn with visualization tools: using learning sciences methods to examine planning processes

Planning researchers traditionally conceptualize learning as cognitive changes in individuals. In this tradition, scholars assess learning with pre- and post-measures of understandings or beliefs. While valuable for documenting individual change, such methods leave unexamined the social processes in which planners think, act, and learn in groups, which often involve the use of technical tools. The present interdisciplinary research program used Learning Sciences research methods, including conversation analysis, interaction analysis, and visualization of discourse codes, to understand how tools like agent-based models and geographic information systems mediate learning in planning groups. The objective was to understand how the use of these tools in participatory planning can help stakeholders learn about complex environmental problems, to make more informed judgments about the future. The paper provides three cases that illustrate the capacity of such research methods to provide insights into planning groups’ learning processes, and the mediating roles of planning tools.     

The social context of childcare practices and child malnutrition in Niger's recent food crisis

In 2004–05, Niger suffered a food crisis during which global attention focused on high levels of acute malnutrition among children. In response, decentralised emergency nutrition programmes were introduced into much of southern Niger. Child malnutrition, however, is a chronic problem and its links with food production and household food security are complex. This qualitative, anthropological study investigates pathways by which children are rendered vulnerable in the context of a nutritional 'emergency'. It focuses on household-level decisions that determine resource allocation and childcare practices in order to explain why practices apparently detrimental to children's health persist. Risk aversion, the need to maintain self-identity and status, and constrained decision making result in a failure to invest extra necessary resources ingrowth-faltering children. Understanding and responding to the social context of child malnutrition will help humanitarian workers to integrate their efforts more effectively with longer-term development programmes aimed at improving livelihood security.     

Social feeding in ladybird beetles: adaptive significance and mechanism

Summary. Young larvae of Adalia bipunctata search an area more intensively when exposed to the odour from other larvae feeding on aphids than when exposed only to the odour of aphids. In an olfactometer young larvae were significantly attracted either to the odour of crushed aphids or larvae feeding on aphids, but not to that of aphids, larvae, larvae plus aphids or larvae feeding on an artificial diet. That is, the change in searching behaviour appears in response to a volatile released by aphids when attacked. The odour released by crushed aphids is made up entirely of aphid alarm pheromone, β-farnesene. It is likely that the adaptive significance of this response is that it increases the ability of larvae to locate larvae that have already caught prey. By sharing the aphid kill of another larva it is likely that a first instar ladybird larva greatly increases its probability of surviving to the next instar. It is suggested that this social feeding is facilitated by egg clustering, which also may additionally account for why aphidophagous ladybirds lay their eggs in clusters.

Comparative analysis of the population structure of social vole (Microtus socialis Pall., 1773, cricetidae, rodentia) in different areas of its range

A comparative analysis of the spatial-ethological structure of social vole (Microtus socialis Pall.) colonies was made on the basis of studies performed in Dagestan (1987–1991) and the southern Kalmyk Republic (1993–1998). Notwithstanding differences in environmental conditions and the extent and forms of anthropogenic impact, the population structure of the species proved to be similar and stable. Irrespective of population density, its core consists of family groups. Specific features of social behavior (aggressiveness toward unfamiliar animals) provide for the protection of home ranges and help to maintain a stable population structure.     

跨流域调水的公正问题——基于环境正义的分析视角

水资源时空分布不均造成的水资源短缺问题已成为阻碍区域发展的重要因素。为了应对区域间的水资源短缺问题,跨流域调水工程作为不同流域水资源优化配置的一种手段,被广泛用于解决水资源分配不均和区域需水不平衡问题。调水工程虽然短期内缓解了水资源压力,平衡了区域间用水需求,但其建设和运营过程对工程所涉区域的地方经济、地理环境、人文环境以及生态环境也造成不同程度的压力。本文通过对当前世界范围内跨流域调水工程的文献回顾,围绕跨流域调水工程所引发的社会公平正义层面的争议,借助环境正义理论的分析方法,通过对国内外调水案例的实践分析,追踪相关环境不公的现象和争议,剖析当前社会—生态冲突的产生机制。最后从我国水生态文明建设实际出发,提出以建立健全水权交易市场,构建"赋权—认同—合作"参与机制和树立"人类命运共同体"理念的解决对策,以期降低调水工程对环境和社会所造成的负面影响,推进水生态正义体系的建设。
