NSF Climate Smart Food-Energy-Water Nexus in Smalls Farms (CFEWS)

This global center project is missioned to create climate-smart nexus of food, energy, and water (FEW) systems in small farms (CFEWS) based on the principles of circular bioeconomy. The overarching Goal of the project is to develop a scalable platform for integrating siloed research and translating them into tangible solutions that ensure the prosperity of climate-vulnerable small farms as generally depicted in Figure 1. In brief, the proposed CFEWS provides five interleaved circular services (i.e., renewable energy generation, increased crop production, precision water management, biowaste fertilization, accelerated soil restoration, and enhanced socioeconomic sustainability) while making small farms self-sustaining, carbon-negative, profitable, and public acceptable:

Specific Aims of the project are to (1) design weather sensor-driven angle-adjustable solar arrays above crop canopy to generate electricity and meanwhile increase crop production by providing shading to crops at adverse radiation times, (2) utilize the solar arrays to collect and divert rainwater to on-site underground tank or wetland ponds for subsequent precision irrigation, (3) produce hydrogen/biogas from livestock manure, (4) convert crop residues into ammonia fertilizers, (5) accelerate soil restoration, (6) promote socioeconomic sustainability, and (7) train future workforce in circular bioeconomy systems and research translation.
