By 2050, the UN estimates that 52 percent of the world’s population will be at risk for water insecurity. Climate change is threatening water availability through increased temperatures and drought, unpredictable rain, and the growing threat of more pollution. Globally, most wastewater reenters the water cycle without being treated, introducing dangerous unseen particles including pharmaceuticals, diseases, and larger waste products such as plastics.

Autonomous vehicles (AVs) are revving up in China. As part of the 2018 CCTV Spring Festival Gala, more than one hundred AVs swerved perfect 8’s on the Hong Kong-Zhuhai-Macao Bridge, showcasing Baidu Apollo’s latest AV technology. China is a latecomer to the automotive industry, but it is taking the wheel in autonomous driving technologies and electric and hydrogen cars, viewing the sector as an unprecedented opportunity to play catchup with the rest of the world (See China Environment Forum webinar on China’s new energy vehicle trends below). Companies in China and around the world want to tap into the lucrative autonomous technology market that could reach $2.3 trillion by 2030.

“Resilience isn’t an outcome, it is a process—and capacity-building is crucial,” said Chelsea Keyser, Deputy Chief of Party for USAID’s PREPARED program, during a recent event at the Wilson Center marking the end of the five-year project. PREPARED (Planning for Resilience in East Africa Through Policy, Adaptation, Research, and Economic Development) developed 14 different tools to help communities adapt to the impacts of the changing environment in the East African region, including unreliable rainfall and rising temperatures.

The first U.S. city to host a docked bike-share system, Washington, D.C., is now home to a rapidly growing influx of dockless bikes, with five companies vying for the market. The docked system still accounts for 87 percent of the shared bikes in the United States, but the number of dockless bikes—which can be located by riders using an app and then left anywhere—is growing rapidly. The data from these location-enabled bikes provide a unique opportunity to measure the point-to-point transportation needs of millions of people in some of the world’s densest cities.

In 2016, the Environmental Protection Agency charged its federal advisory committee with exploring how citizen science and crowdsourcing should be integrated into the agency’s mission. The resulting report eloquently describes how if the environment is to be protected then it’s the duty of all – the government, institutions, and citizens – to work together to achieve this.

Our nine-part “Choke Point: Tamil Nadu” series with Circle of Blue has been a must-read on the conflicting demands for water, food, and energy in the South Indian state. In May’s most popular post, S. Gopikrishna Warrier introduces us to Chennai’s tech-savvy social entrepreneurs, who are providing the city’s residents with real-time information on the risk of flooding. (The ninth and final post in the series was published yesterday; catch up on all of them at “Choke Point: Tamil Nadu”).

In 2000, the United Nations established the Millennium Development Goals (MDGs) with the goal of creating a global partnership for development. The formation of the MDGs created a foundation for collaboration and encouraged cross-sector partnerships to reduce poverty but also promote issues like environmental sustainability and gender equality. To carry on momentum from the MDGs, 17 Sustainable Development Goals (SDGs) were established in 2015 to further encourage partnerships between civil society organizations, the private sector, academic institutions, and more. Increased private sector engagement in development is a major goal of the SDGs – and we would argue that it is crucial to their success.

Before the 2015 floods that drowned Chennai, Pradeep John spent several years posting thorough and dutifully accurate updates and alerts on Twitter and Facebook as the Tamil Nadu Weatherman. An amateur meteorologist who developed considerable expertise in weather data and satellite imagery, John’s online followers relied on his crisp forecasts and advice.
