For solar industry professionals in China, May 31, 2018, is a day that will live in infamy. At the beginning of 2018, Chinese domestic solar developers were riding a high after reaching a record 53 GW of newly installed solar capacity the previous year. Most sources projected this breakneck pace of new solar construction would continue through 2018. On June 1, 2018, however, the National Development and Reform Commission, Ministry of Finance, and National Energy Agency announced a new policy to lower the solar feed-in-tariff, halt subsidized utility-scale development, and implement a quota for distributed projects. Industry professionals refer to the infamous policy as “531” for May 31, 2018, the day that the solar industry ground to a temporary halt or “freezing point.”

While the U.S. has been fixated on President Trump’s contentious border wall project, another more ominous threat facing Guatemalans is building internally. In a swift reversal, many politicians and scholars who have previously argued for directing increased U.S. aid to communities in Central America’s Northern Triangle—Guatemala, El Salvador, and Honduras—as a humanitarian alternative to the border wall, are now calling on Congress to suspend some forms of aid to Guatemala, which they now see as the more humane option.

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.

From the cultural hub of Lahore down to the bustling ports of Karachi, smog is king in Pakistan, with citizens enduring unhealthy air quality for much of the year. The smog, generated mostly by crop and garbage burning and diesel emissions from furnaces and cars, could get worse by the end of this year when Pakistan opens five new Chinese-built coal power plants, funded by a $6.8 billion venture under the China-Pakistan Economic Corridor (CPEC) initiative. These five plants are just the beginning of the Pakistan government’s planned 7,560 MW expansion in coal power, which are CPEC-energy priority projects. “It’s a perfect storm for a pollution crisis,” said Michael Kugelman of the Wilson Center’s Asia Program. “The poor will continue to burn a variety of polluting materials to produce fuel, and now you’re also going to be introducing dirty coal into the mix. Combine that with crop burning in the countrywide and car exhaust fumes in rapidly growing cities, and you’ve got a really smoggy mess on your hands—and in your lungs.”

After close to 40 years of armed conflict, Afghanistan may be poised to begin a period of economic recovery. Electrifying remote areas and establishing pervasive political control is critical to its success. India is currently planning and funding several major hydropower projects along the Kabul River and its tributaries. Micro-hydropower is bringing electricity to remote areas such as the Banda Miralamji Village in eastern Nangarhar Province. However, in some areas far from the capital, the central government in Kabul and opposition groups are struggling for control and influence. While electrification of a village often eases poverty, health concerns, and improves communication, it does not always benefit the government in Kabul.

This year, 2018, marks the 60^th anniversary of a landmark publication by a pair of academic social scientists who first recognized the close relationship between population age structure (the distribution of a country’s population, by age) and development. In Population Growth and Development in Low Income Countries (Princeton U. Press, 1958), demographer Ansley Coale (1917-2002) and economist Edgar M. Hoover (1907-1992) theorized that eventual declines in fertility would transform developing-country age structures. Coale and Hoover demonstrated that these newly transformed age structures would exhibit larger shares of citizens in the working ages, and smaller shares of dependent children and seniors (Fig. 1). This transition, they argued, would someday help lift countries with youthful populations in Asia, Latin America, and Africa out of the low-income bracket.

Huo Chang grows visibly exasperated as he speaks about his city’s water crisis. From his office in Beijing’s largest state-owned environmental investment and service company, China Energy Conservation and Environmental Protection Group (CECEP), the water expert explains how Beijing is in the throes of a population and economic boom that has left its water resources both polluted and depleted. In response to these opposing pressures, the city turned to controversial measures to avoid a Cape Town-like Day Zero crisis in which Beijing would no longer be able to meet the daily water needs of its population of nearly 22 million.

Once again, we find ourselves witnessing another calamitous hurricane event in the United States, just weeks after a George Washington University report estimated that nearly 3,000 more people died in the 6 months following last year’s Hurricane Maria than would have without the hurricane. We have been here before, too many times. With each and every major disaster, the scientists who study public health in crises ask ourselves, is what we have learned and shared being taken seriously—or is it just being ignored? The response to Hurricane Maria, which devastated Puerto Rico last year, is just one more example where we have to ask if our work is valued by those who have the political power to improve public health. The staggering number of excess deaths—most of whom died after the storm—point to a deadly lack of prevention and preparedness, particularly in the public health system.
