Energy efficiency in buildings in China: Policies, barriers and opportunities

"China's rising energy demands that are required for its booming economy have made the country one of the biggest emitters of greenhouse gases. The Chinese building sector substantially contributes to the country's CO2emissions. Chinese policy makers have realized that enhancing energy efficiency in buildings (EEB) is a promising approach with regard to combining further economic growth with less energy consumption and environmental impact. They have enacted a wide range of policies to foster energy efficiency within the building sector. While the policies can theoretically unfold a great energy saving potential, their implementation has been weak so far. This study analyzes the existing policies and measures in place in order to promote EEB and examines promoting factors as well as barriers for the implementation of EEB policies. The study comes to the conclusion that the determinants of successful EEB policy implementation in China arise in the fields: legal environment and enforcement, economic parameters for investment, informational and lifestyle aspects as well as the specific organization of the value chain in the housing sector."

Topic modelling exposes disciplinary divergence in research on the nexus between human mobility and the environment

Human mobility is increasingly associated with environmental and climatic factors. One way to explore how mobility and the environment are linked is to review the research on different aspects of the topic. However, so many relevant articles are published that analysis of the literature using conventional techniques is becoming prohibitively arduous. To overcome this constraint, we have applied automated textual analysis. Using unsupervised topic modelling on 3197 peer-reviewed articles on the nexus between mobility and the environment published over the last 30 years, we identify 37 major topics. Based on their language use, the topics were deeply branched into two categories of focus: Impact and Adaptation. The Impact theme is further clustered into sub-themes on vulnerability and residential mobility, while articles within the Adaptation theme are clustered into governance, disaster management and farming. The analysis revealed opportunities for greater collaboration within environmental mobility research, particularly improved integration of adaptation and impact research. The topic analysis also revealed that, in the last 30 years, very little research appears to have been undertaken in migration destinations or on the fate of environmentally influenced migrants during their migration process and after arriving in a new location. There are also research gaps in gender and Indigenous issues within the Impact theme, as well as on adaptive capacity and capacity-building

The Nagoya Protocol: Fragmentation or Consolidation?

In October, 2010, a protocol on access and benefit-sharing (ABS) of genetic resources was adopted, the so-called Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity. Before the adoption of the Nagoya Protocol, the governance architecture of ABS was already characterized by a multifaceted institutional environment. The use of genetic resources is confronted with many issues (conservation, research and development, intellectual property rights, food security, health issues, climate change) that are governed by different institutions and agreements. The Nagoya Protocol contributes to increased fragmentation. However, the question arises whether this new regulatory framework can help to advance the implementation of the ABS provisions of the Convention on Biological Diversity (CBD). This paper attempts to find an answer to that question by following three analytical steps. First, it analyzes the causes of change against the background of theories of institutional change. Second, it aims to assess the typology of the architecture in order to find out if this new set of rules will contribute to a more synergistic, cooperative or conflictive architecture of ABS governance. Third, the paper looks at the problem of “fit” and identifies criteria that can be used to assess the new ABS governance architecture with regard to its effectiveness
