Title : Sustainable land management by agrivoltaics in Colombia’s post-conflict regions: An integrated approach from the water–energy–food nexus
Abstract:
Background: Agrivoltaic (AV) systems, which integrate agricultural production with photovoltaic energy generation, have emerged as a solution for sustainable land management. However, their application in post-conflict settings remains underexplored. This study focuses on the PDET and ZOMAC municipalities in Colombia, areas that face a range of socio-economic and environmental challenges, where AV can offer a dual benefit of energy generation and improved agricultural productivity.
Objective: To evaluate the potential of AV for sustainable land management in Colombia’s post-conflict regions, extending the traditional Water–Energy–Food (WEF) nexus to include Soil, Climate, and Communities (WEFSCC) dimensions.
Methods: The research utilized a multi-disciplinary framework, combining GIS-based site characterization, crop yield modeling, water balance modeling, and photovoltaic performance simulations for 30 kW systems. Economic assessments were performed using Net Present Value (NPV), Internal Rate of Return (IRR), and Free Cash Flow (FCL) indicators, with sensitivity analyses on crop yields, energy tariffs, and installation costs. The results were integrated within the WEFSCC framework to assess the trade-offs and synergies across these dimensions.
Results: Agrivoltaic systems were found to reduce crop irrigation demand by up to 40%, while generating 17 MWh/month of electricity per site. The economic analysis showed positive results, with Cabrera showing higher profitability than Pisba, driven by differences in yield and energy generation. The study confirms the potential of AV as sustainable solutions for land restoration, community resilience, and climate adaptation in Colombia's post-conflict territories.
Conclusion: The AV offer a feasible, economically viable solution for rural regions in Colombia, improving both agricultural productivity and energy security. By integrating renewable energy into farming systems, AV not only promote sustainable development but also provide resilience in post-conflict areas, contributing to environmental recovery and food security. The current expansion of this research, including the use of HOMERPro, will further refine the economic, ecological, and energy-related impacts, offering insights for similar regions worldwide.
