In the heart of Italy, a region known for its rich agricultural heritage and stunning landscapes, a groundbreaking study is challenging the status quo of renewable energy development. The Apulia region, with its vast expanses of farmland, is at the center of a debate that could redefine how we balance energy production and food security. At the forefront of this research is Anna Rita Bernadette Cammerino, a researcher from the Department of Science of Agriculture, Food, Natural Resources and Engineering at the University of Foggia. Her work, published in the journal ‘Agronomy’ (translated from Italian), offers a compelling vision for the future of agrivoltaics—a technology that combines solar energy production with agricultural activities.
The European Union’s ambitious goal of generating 55% of its electricity from renewable sources by 2030 has put significant pressure on member states to accelerate their energy transitions. Italy, in particular, is lagging behind, and the Apulia region is no exception. With a need to add 7.4 GW of installed renewable energy capacity by 2030, the region faces a critical challenge: how to meet this demand without compromising its valuable agricultural land.
Cammerino’s study, conducted using a sophisticated GIS-based analysis, provides a roadmap for integrating agrivoltaics into the region’s energy strategy. “Agrivoltaics offers a unique opportunity to address the dual challenges of energy production and food security,” Cammerino explains. “By co-locating solar panels with agricultural activities, we can minimize land-use conflicts and support sustainable development.”
The research involved a three-step approach to assess land use and potential agrivoltaic opportunities. First, the team identified protected areas and constraints using the Apulian Landscape Plan to create a Constraint Map. Next, they analyzed agricultural land use, capability, slope, and exposure to develop an Availability Map. Finally, they modeled agricultural land conversion scenarios to quantify the potential capacity of future agrivoltaic installations.
The results are striking. A mere 0.25% occupation of utilized agricultural land could yield a regional installed agrivoltaic capacity of 1.3 GW, while doubling this percentage would double the installed capacity to 2.6 GW. These figures translate to 3.25 and 6.50 thousand hectares of land, respectively, contributing significantly to the region’s 2030 renewable energy targets.
For the energy sector, the implications are profound. Agrivoltaics represents a new frontier in renewable energy development, one that aligns with the growing demand for sustainable and environmentally friendly solutions. By integrating solar energy production with agriculture, companies can tap into new revenue streams, enhance their corporate social responsibility profiles, and contribute to the global fight against climate change.
Cammerino’s work, published in Agronomy, underscores the need for effective spatial planning to manage the risks of land-use changes. “We must strike a balance between energy production and agricultural activities,” she emphasizes. “Agrivoltaics offers a pathway to achieve this balance, but it requires careful planning and stakeholder engagement.”
As the world grapples with the challenges of climate change and energy security, Cammerino’s research offers a beacon of hope. By embracing agrivoltaics, regions like Apulia can lead the way in sustainable energy development, demonstrating that it is possible to meet our energy needs without sacrificing our agricultural heritage. The future of energy production is not just about generating electricity; it is about creating a sustainable and resilient food-energy-water nexus. And agrivoltaics, with its unique blend of innovation and tradition, is poised to play a pivotal role in this transformation.
