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 CO. 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.
由于没有任何单一的碳捕获和封存解决方案能够将全球气温上升幅度限制在 1.5-2.0°C 以内，因此需要采取额外的气候稳定措施来补充当前的减排方法。城市农业提供了一种易于采用的实现碳中和的途径，可以利用广阔的城市表面区域来种植粮食，同时吸收 CO₂。城市农业涉及广泛的表面区域，如屋顶、阳台和垂直空间，允许土壤存在并通过空气与土壤接触进行大气碳封存。在这个观点中，我们还提倡将增强的岩石风化（ERW）纳入城市农业，为这一在全球范围内得到认可并逐渐得到广泛应用的负排放技术提供进一步的机会。
