    Ultrafast desalination

    Finding more efficient membranes for water desalination can increase the availability of clean water with reduced environmental impacts. Jiang and colleagues show that a membrane design based on a covalent organic framework can address the problem of low permeation flux and achieve ultrafast desalination.

    Tropical forest carbon loss

    Tropical forests store huge reserves of carbon but are under growing assault. Using satellite data, Zeng and colleagues show that annual carbon loss in tropical forests more than doubled between 2001 and 2019. Agricultural activities are driving most of this loss.

    Greening batteries

    The rapid proliferation of batteries in a wide range of applications has put problems with their sustainability under greater public scrutiny. In this issue we highlight research on emerging cell chemistry and cathode materials that addresses the worrying reliance on lithium and cobalt, as well as a Review Article on sensing techniques to monitor the health of batteries for extended lifespan.

    Costs and benefits of the Great Green Wall

    The Great Green Wall programme aims to restore 100 million hectares of degraded ecosystems across various countries in the Sahel region (pictured). Mirzabaev and colleagues evaluated the economic costs and benefits of future land restoration projects under this programme.
