Political conservatism,religion, and environmental consumption in the United States

The role of political conservatism and religion in shaping attitudes toward environmental consumption in the US is examined. Previous research suggests that while there is a mixed relationship between religiosity (measured in various ways) and environmentalism, political conservatives are unlikely to support pro-environment measures. Using nationally representative survey data, mixed results are found regarding the relationship of religiosity and environmental consumption: religious attendance and religious identity are positively related to environmental consumption, while belief in an involved God and biblical literalism are negatively related. Increased levels of religiosity, however, mute the otherwise strong negative effect of political conservatism. This suggests, surprisingly, that Green marketers and activists are likely to face less conservative resistance to environmental consumption among religious Americans.     

The importance of compatible beliefs for effective climate policy integration

ABSTRACT

European climate policy faced increasing constraints during the economic and Eurozone crises (2008–2014). The European Commission subsequently refocused policymaking toward integrating climate objectives into other policy areas such as energy and the 2014–2020 European Union (EU) budget. The conditions for successful climate policy integration (CPI) are analyzed, focusing on the compatibility of key actors’ beliefs. In renewable energy policy, CPI was successful as long as the co-benefits and related policy-core beliefs of energy security, rural economic development and climate action coexisted harmoniously. Once conflict among these policy-core beliefs emerged during the biofuels controversy, CPI was weakened as actors with competing economy-focused beliefs controlled the decision-making process. The case of EU budget climate mainstreaming illustrates how actors can add climate objectives into legislation despite meaningful discussion being ‘crowded out’ by other priorities. The findings highlight the importance of low conflict between departments, compatible beliefs and policy priorities for successful CPI.     

太湖水体光学特征及其对水中初级生产力的影响

对太湖梅梁湾水体实测结果表明 :在水体表面 ,UV -C的强度较小 ,只有 10 -5μE·m-2 ·s-1数量级 ;UV -B的强度随着波长的增加而呈现递增的趋势 ;UV -A的强度较强 ,达 10 -2 μE·m-2 ·s-1数量级 ,并且在水体中衰减较快 ,衰减系数 (Kd)可以达到 12 .5m-1。可见光在水体中Kd 可达 8.2m-1。在水下 0 .5m处 ,紫外线不足表面光强的 1% ,可见光是表面光强的 2 0 %左右。初级生产力在表面相对较小 ,在水下 0 .2m处最大 ,且随水深的增加而减少 ;在水体中直接测定发现 ,0 .2m处溶解氧值较高。初级生产力的这种分布是水体中紫外光与可见光共同作用的结果。     

Biophysical energy analyses of non-market values of the Ebro Delta

Non-market values were estimated with energy analysis under four land cover scenarios in the Ebro Delta, Spain. The market value of agriculture, the primary use value, is compared. Conversion of the natural landscape to agricultural fields has resulted in a drop in total annual non-market value from $721 million in the pristine scenario to $11 million in the present scenario. The market value of the agricultural crops has risen over time, from $10 million to almost $52 million, contributing the major portion of the total value of the Delta. However, the rate of return has decreased from the pristine to the present delta, indicating that more energy is required to produce a smaller output. Energy analyses reveal that one form of value—non-market value—is being traded for another—market value.

石油类物质的湿沉降及其对区域水环境的影响:以正构烷烃为指示物

为评估含有机污染物的湿沉降对区域水环境污染的贡献,在广州市3个采样点(海珠区、天河区和萝岗区)采集了2010年湿沉降样品(157个),并在天河点采集了12个干沉降、11个地表径流及10个气溶胶样品,并对其中指示化合物正构烷烃的浓度、来源和通量进行分析.正构烷烃(包括从C20—C34的15种同系物)总浓度范围为0.6—292μg·L-1;从季节上看,其在雨季(4—9月)的浓度低于旱季(1—3月和10—12月).碳优势指数和主成分分析结果表明,广州市的正构烷烃主要来源于石油产品的消费(50%),暗示石油产品消耗是主要污染源;其次来自植物排放(38%).此外,广州市在2010年有55±80 t(平均值±标准偏差)正构烷烃经干沉降和湿沉降至地表,其中湿沉降的贡献为39±80 t.同时,大约有224±296 t正构烷烃通过地表径流进入到珠江,反映了面源污染对区域水环境影响很大.因此,控制石油产品的消费和治理地表径流,是抑制面源污染、改善区域水环境的两个途径.

Global population collapse in a superabundant migratory bird and illegal trapping in China

Persecution and overexploitation by humans are major causes of species extinctions. Rare species, often confined to small geographic ranges, are usually at highest risk, whereas extinctions of superabundant species with very large ranges are rare. The Yellow‐breasted Bunting (Emberiza aureola) used to be one of the most abundant songbirds of the Palearctic, with a very large breeding range stretching from Scandinavia to the Russian Far East. Anecdotal information about rapid population declines across the range caused concern about unsustainable trapping along the species’ migration routes. We conducted a literature review and used long‐term monitoring data from across the species’ range to model population trend and geographical patterns of extinction. The population declined by 84.3–94.7% between 1980 and 2013, and the species’ range contracted by 5000 km. Quantitative evidence from police raids suggested rampant illegal trapping of the species along its East Asian flyway in China. A population model simulating an initial harvest level of 2% of the population, and an annual increase of 0.2% during the monitoring period produced a population trajectory that matched the observed decline. We suggest that trapping strongly contributed to the decline because the consumption of Yellow‐breasted Bunting and other songbirds has increased as a result of economic growth and prosperity in East Asia. The magnitude and speed of the decline is unprecedented among birds with a comparable range size, with the exception of the Passenger Pigeon (Ectopistes migratorius), which went extinct in 1914 due to industrial‐scale hunting. Our results demonstrate the urgent need for an improved monitoring of common and widespread species’ populations, and consumption levels throughout East Asia.
