Как деревья оздоровляют города

ВАШИНГТОН – В мае прошлого года я имел сомнительное счастье посетить Мумбаи, Индия, в самый жаркий месяц, зарегистрированный в городе. Температура оставалась на уровне более чем 40 °C (104 °F) несколько дней подряд. Разница между нахождением в тени дерева и под палящим солнцем была как день и ночь.

Такая жара не просто некомфортна. Она представляет собой серьезную угрозу для здоровья – ту, которая часто упускается из виду при решении экстремальных погодных условий.

В действительности, жара насчитывает больше смертей, чем любое другое явление, связанное с погодой, ежегодно убивая более 12000 человек во всем мире. Опасность имеет особенно выраженный характер в городах, где эффект “городского теплового острова” приводит к температурам на целых 12 °C выше, чем в близлежащих менее развитых районах. И проблема не ограничивается тропическими городами, как Мумбаи. В августе 2003 года, разрушительная жара по всей Европе, только в Париже, унесла жизни более 3000 человек.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
