Sustainability in New Zealand's quota management system: A convenient story

New Zealand's fisheries management institutions represent a globally recognised story of a successful sustainable management regime, an accolade perceived to be based on its early and comprehensive adoption of a quota management system (QMS). This article questions these assumptions. There are three main strands to the argument. First, that the interpretation of sustainability in the New Zealand QMS disregards the social while simultaneously accentuating a particularly neoliberal economic paradigm in which sustainability is directed towards sustaining the wealth generating potential of quota holdings. Second, while in theory there is a separation of biological and economic conceptions of sustainability in the QMS, these processes are, in fact, deeply intertwined. Third, that the sustainability brand works to legitimise the privatisation and marketization of marine environments, to protect the income stream of quota investors, and to effectively incorporate and discipline dissent.     

Magnetic field measurements on four yellow supergiants. I

Multiyear high precision measurements of the longitudinal component of the magnetic field (B_e) of four supergiants are reported: Aqr (G0 Ib), Aqr (G2 Ib), Gem (G8 Ib), and Peg (K2 Ib). The best measurement accuracy, =0.8 G, was achieved for Peg. A Monte Carlo method was used to test the reliability of the derived measurement errors. The differences between the observational errors and the calculated Monte Carlo errors were 3.2%. For Aqr and Aqr no statistically significant value of the magnetic field was recorded when averaged over a night. For eGem the following overnight average values of the magnetic field were recorded on five nights: 11.1±2.7 G, 9.8±2.5 G, –10.5±3.0 G, 38.1±7.4 G, and 5.3±1.5 G. For Peg the magnetic field recorded over two nights was –5.3±0.9 G and – 2.7±0.8 G.Translated from Astrofizika, Vol. 48, No. 1, pp. 15–28 (February 2005).     

Empirical behavior of Chayes'' null model

Chayes' t-test for closure correlations is developed from various approximations and assumptions. The empirical behavior of this test is observed through the use of random-sampling number matrices of order to thirteen. The experiments demonstrate a lower limit for the reliability of Chayes' model of about 91/100. That is, about one chance in ten remains that an error due to the statistical testing is committed on some product-moment correlations in a given matrix of correlation, given a confidence level of 90 percent. With increase in the number of variables, the test for departure from zero correlation can be used provided the sample size remains small.

金沙江下游及三峡段水文气象因子演变与响应的分析

对金沙江下游及三峡段3个水文站1954~2008年径流序列和2个气象站1951~2008年降雨、气温序列运用滑动平均法和Mann-Kendall法进行趋势性检验,利用有序聚类法、均值检验法分析突变性及小波分析法进行周期性诊断,并应用Pearson法对径流、降雨和气温的相关关系进行研究。研究表明:(1)研究区径流量的年内分配不均匀性和年际变化不显著。(2)金沙江下游段屏山站的径流量呈上升趋势,并在1997年发生突变,但该区域宜宾站的降雨量呈下降趋势并在1991年发生突变;三峡段寸滩站和宜昌站的径流量呈下降趋势,分别在1968年和2005年发生突变,同时该区域沙坪坝站的降雨量呈上升趋势并在1961年和1995年发生突变。(3)径流和降雨时间序列都存在小于10a的主周期以及20a以上的次周期。(4)各水文站夏季径流量受同期降雨量和同期气温的共同影响,而秋季径流量受前期气温的影响最大。     

What happens after climate change adaptation projects end: A community-based approach to ex-post assessment of adaptation projects

Over the last decade, hundreds of climate change adaptation projects have been funded and implemented. Despite the importance of these first-generation adaptation projects for establishing funders and implementors’ “best practices,” very little is known about how early adaptation projects have endured, to what ends, and for whom. In this article, I propose a community-based methodology for ex-post assessment of climate change adaptation projects. This methodology contributes to recognitional justice by asking the individuals and collectives tasked with sustaining adaptation initiatives to define adaptation success and what criteria for success should be assessed. I apply this subjective assessment approach in 10 communities across Ecuador that participated in an internationally funded adaptation project that concluded in 2015. My analysis draws together participatory mapping, walking interviews with local leaders, participant observation, and surveys with former project participants. The results highlight that even adaptation projects that were deemed highly successful at their closure have uncertain futures. I find that the sustainability mechanisms that were envisioned by project implementors have not functioned, and communities are shouldering the burden of reviving failing adaptation interventions. These findings highlight that the current model of episodic funding for climate change adaptation projects and evaluation processes needs to be revisited to acknowledge the long-term challenges faced by communities. This analysis also calls attention to the importance of ex-post assessment for adaptation projects and the potential of subjective assessment approaches for building more ontological and epistemological pluralism in understandings of successful climate change adaptation.
