Agrivoltaics: Synergies and trade-offs in achieving the sustainable development goals at the global and local scale

Abstract

The 2015 Sustainable Development Goals (SDGs) provide a set of aspirational objectives for the world, addressing interlinked themes including poverty, hunger, and climate action. Meeting these goals requires a similarly integrated and interdisciplinary approach. One component of such an approach may be agrivoltaic systems (AVS): dual use solar and agricultural systems wherein crops are grown beneath and between solar panels. Given their intersectoral nature, AVS will have complex impacts on the achievement of the SDGs. This analysis seeks to evaluate how AVS could impact progress towards the SDGs based on literature around the impacts of agriculture, solar, and AVS, and the indicators measuring progress towards the SDGs. It uses a Strengths, Weaknesses, Opportunities, and Threats (SWOT) framework and applies it in a unique way to understand the direct and immediate impacts to the SDGs following the installation of an AVS (i.e., strengths and weaknesses), and the potential impacts on the SDGs based on secondary or supplementary actions taken once an AVS is installed (i.e., opportunities and threats). Though the most obvious of AVS' impacts to the SDGs will be on Goals 2 (Zero Hunger) and 7 (Affordable and Clean Energy), evaluation of individual indicators shows that AVS can quantifiably impact 14 out of 17 SDGs, largely in a positive manner. However, evaluating impacts on the SDGs indicator by indicator also reveals possible negative, and unexpected, consequences of AVS. Yet, impacts on the SDGs will vary by location-specific factors such as climate, and so this analysis concludes with an application of the SWOT framework in Ethiopia for a farm where an AVS is under consideration. Altogether, this work should provide a means for evaluating the impacts of AVS on SDGs and insights into how to mitigate possible detrimental impacts while capitalizing on benefits.
