Tahun Pemulihan Laut

OXFORD – Keutamaan laut di dunia tidak dapat dikesampingkan. Laut menyediakan 50% oksigen yang kita hirup, pangan bagi miliaran orang, dan penghidupan bagi jutaan penduduk lainnya. Laut berfungsi sebagai ‘pompa biologis’ yang penting dalam menjaga stabilitas atmosfer dan distribusi panas. Selain itu laut memegang peranan vital dalam mitigasi dampak perubahan iklim. Singkatnya, laut ibarat sekutu terdekat dan kita harus mengerahkan segala daya upaya untuk melindunginya.

Upaya ini semakin diperlukan, mengingat berbagai ancaman yang tidak terduga dan belum pernah terjadi sebelumnya yang tengah kita hadapi. Meskipun laut merupakan faktor penting dalam memperlambat perubahan iklim, menyerap lebih dari 30% emisi gas rumah kaca dan 90% kelebihan panas yang dihasilkan sejak Revolusi Industri, kerugian yang dialami sangat besar. Pengasaman laut dan pemanasan terjadi pada laju yang mengkhawatirkan dan sudah berdampak buruk pada ekosistem laut yang paling berharga – dampak negatif yang akan meluas.

Kini, banyak negara mengalami fenomena yang kemungkinan adalah peristiwa El Niño terkuat dalam sejarah. Cuaca buruk akibat fenomena ini – berasal dari Pasifik tapi mempengaruhi seluruh perairan dunia – diperkirakan mempengaruhi lebih dari 60 juta penduduk tahun ini dan memperparah penderitaan yang terjadi tahun lalu. Keadaan ini menjadi pengingat serius atas kerentanan kita terhadap guncangan, baik itu alami dan dipicu manusia (human-induced) pada sistem bumi.

    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.
