The Role of Social Networks and Trusted Peers in Promoting Biodiverse Carbon Plantings

Social capital has the potential to influence the success of biodiverse carbon plantings in the face of uncertainty amongst rural landholders about the need or efficacy of efforts to address climate change through tree planting. We conducted 17 face-to-face semi-structured interviews with landholders in Victoria, Australia who voluntarily participate in biodiverse carbon plantings on their land, focusing in particular on the role of social capital for understanding how ‘early adopters' can advocate for programs locally. The interviews revealed the importance of social networks and the profound impact of trusted peers on the diffusion of carbon planting schemes. These social capital dimensions are especially important for shaping ongoing participation and the ways in which participants become active agents in trusted relationships that influence the participation of others. Our results suggest that the positive impact of social networks can counteract doubts about the validity of climate adaptation responses such as carbon planting, and enable landholders to connect the program with their existing stewardship motivations. The ability for early adopters of the program to demonstrate the physical materialisation of their plantings to others was vital to this process. We propose that targeting champions and trusted peers in local communities could accelerate the proliferation of biodiverse carbon planting schemes.

Difficulties in accounting for private finance in international climate policy

It is widely acknowledged that private finance has a key role to play in achieving low-carbon development and resilience to climate change. However, while there have been several studies that have closely examined the data on public climate finance, there have been few such studies of the private climate-related finance data. There is a political dimension to accounting for ‘private finance’ given the commitment of industrialized countries – enshrined in the Copenhagen Accord and the Cancun Agreements – to mobilize US$100 billion of public and private finance for developing countries by 2020, on an annual basis. The availability and quality of data for different types of private climate finance flows with climate benefits (investments, carbon market payments, and voluntary funding) are analysed, and these flows are assessed according to various criteria for inclusion in the $100 billion figure. While existing data suggest that private climate finance invested in developing countries and mobilized by industrialized countries might currently be in the range of $27–123 billion per year, this number is a questionable point of reference. Existing data are limited and of very poor quality: definitions of ‘private climate finance’ are missing and data are hardly verified. Therefore, policy makers will first have to clearly define ‘private climate finance’ and develop systems for measuring, reporting, and verifying it, before using private finance numbers in international climate agreements.

Private Car Travel Characteristics and Influencing Factors in Chinese Cities ——A Case Study of Guangzhou in Guangdong, China

Taking Guangzhou as a case, this paper adopted a questionnaire survey to gather first-hand data and analyzed the characteristics and influencing factors of private car travel in Chinese cities. As the research indicated, trip purposes of private car travel are mainly commute and business affairs with a more flexible trip in the urban core area. And trip intensities are concentrated in a certain extent, with trip frequency being lower in the urban core area than the peripheral area. In addition, the trip time has two significant peaks occurring in the morning and afternoon, and one trough in the midday. And trip spatial distribution is mainly within commute with both residence and employment in urban area and inward commute with residence in suburban area while employment in urban area. Both kinds of commutes direct to the urban area. The study also shows that the characteristics of private car travel are principally influenced by two aspects: travelers’ attributes and urban characteristics. The main travelers’ social and economic attributes influenced it include the gender, education attainment, age, driving experience and per capita monthly household income. The urban characteristics influenced it mainly cover the land use pattern, public traffic facilities and spatial attributes of residential environment.

民间力量参与海上公益性救助的激励机制探析

海难救助可以界分为公益救助与私益救助两类。民间力量参与海上公益救助具有重要的现实意义。海商法中以民事请求权思路为主的救助激励机制能有效激励私益救助,却不足以充分保障参与海上公益救助的民间主体之权益。应适当跳出海商法学的框架,借助行政法学的视角,根据海上公益救助的具体情形,由国家对参与救助的民间主体给予不同性质的补偿或奖励,以弥补私法逻辑的局限,为其积极参与海上公益救助解除经济利益损失的后顾之忧。
