With no single carbon capture and sequestration solution able to limit the global temperature rise to 1.5–2.0 °C by 2100, additional climate stabilization measures are needed to complement current mitigation approaches. Urban farming presents an easy-to-adopt pathway toward carbon neutrality, unlocking extensive urban surface areas that can be leveraged to grow food while sequestering CO₂. Urban farming involves extensive surface areas, such as roofs, balconies, and vertical spaces, allowing for soil presence and atmospheric carbon sequestration through air-to-soil contact. In this viewpoint we also advocate the incorporation of enhanced rock weathering (ERW) into urban farming, providing a further opportunity for this recognized negative emissions technology that is gaining momentum worldwide to gain greater utilization.

具有增强岩石风化作用的城市农业作为未来的气候稳定楔

由于没有单一的碳捕获和封存解决方案能够到 2100 年将全球温度升高限制在 1.5-2.0 °C，因此需要采取额外的气候稳定措施来补充当前的减缓方法。城市农业为实现碳中和提供了一条易于采用的途径，开启了广阔的城市表面积，可用于种植食物，同时封存 CO ₂. 城市农业涉及广阔的表面积，如屋顶、阳台和垂直空间，允许土壤存在和通过空气与土壤接触的大气碳封存。从这个角度来看，我们还主张将增强型岩石风化 (ERW) 纳入城市农业，为这种公认的负排放技术提供进一步的机会，该技术正在全球范围内获得更大的利用势头。
