Crowdfunding is a rapidly growing funding model that has recently expanded as a way to support urban improvement projects. A number of platforms promote citizen-designed civic projects to help them raise small amounts of money from many donors. Parks, gardens, and other urban beautification initiatives are some of the most common projects funded on these platforms, though several projects show the potential for crowdfunding as a means to fund much larger initiatives. In Rotterdam, Netherlands, citizens have used crowdfunding to fund a wooden footbridge that aims to be a catalyst for economic development in the region. In Glyncoch, Wales, citizens donated a total of £792,021 (US$ 1.31 million) for a multi-purpose community center.
How can city governments utilize the potential for civic crowdfunding? More than 170 cities have already signed up to use Citizinvestor.com, a crowdfunding platform that raises money for public projects. Recently launched Citizinvestor Connect will allow cities to go further by creating their own platforms. This will allow cities to source project ideas from citizens, who can use the platform to raise money for an initiative that the government agrees to help implement.
When the world’s largest working advanced digestion plant opened last month, it showed the power- hungry process of treating waste in the $360 billion water industry can be self-sufficient in terms of energy use.
According to a report by the Energy Information Administration, wind curtailments in Texas have dropped steadily and substantially since 2011 thanks mostly to the state’s completion of 3,500 miles of transmission lines as part of the Competitive Renewable Energy Zones program.
Extreme events, a type of collective behavior in complex networked dynamical systems, often can have catastrophic consequences. To develop effective strategies to control extreme events is of fundamental importance and practical interest. Utilizing transportation dynamics on complex networks as a prototypical setting, we find that making the network [ldquo]mobile[rdquo] can effectively suppress extreme events. A striking, resonance-like phenomenon is uncovered, where an optimal degree of mobility exists for which the probability of extreme events is minimized. We derive an analytic theory to understand the mechanism of control at a detailed and quantitative level, and validate the theory numerically. Implications of our finding to current areas such as cybersecurity are discussed.
Implementing policies to curb carbon emissions dramatically cuts health care costs associated with poor air quality — in some cases, by more than 10 times the cost of policy implementation, according to new research published in Nature Climate Change. Policies aimed at reducing carbon emissions are as effective as laws targeting polluting compounds like ground-levelRead More
Ljubljana, Slovenia has won the 2016 European Green Capital Award, given annually by the European Commission to cities that set an example of sustainable urban development best practices.
With an ambitious sustainability plan and that has led to significant improvements in the past decade, the capital of Slovenia joins cities such as Bristol, elected as the 2015 winner and Copenhagen, elected as the 2014 winner. The award considers the city’s urban and environmental management strategies and commitment to sustainability. Specifically, the European Commission takes into account indicators such as climate resilience, urban mobility, air quality, waste management, and water quality among other factors.
