Abstract Resources, energy, and food are interconnected global challenges. Herein, a double‐layer hierarchical photothermal network (HPN) is designed to co‐harvest clean water boron. As known, this the first achieve above aims together. concept demonstration, graphene oxide (GO) hydrogel with vertically aligned GO nanosheets served as upper layer for light adsorption, while Mg(OH) 2 /GO acted bottom boron extraction. HPN demonstrated high evaporation rate of 1.87 kg m −2 h −1 , an efficiency 89.9% under 1 sun. Combined evaporation‐induced convection effect, localization concentration field, temperature showed record extraction capacity 789.5 mg solar irradiation, versus just 112.16 dark conditions. The contributions these enhanced factors 59.6%, 30.1%, 10.3%, respectively. Ultimately, extracted significantly increased germination growth irrigated crops. In conclusion, offers novel approach provides innovative solution advance achievement Sustainable Development Goals (SDGs).
