Mapping potential conflicts between photovoltaic installations and biodiversity conservation

Resumo:European countries are expanding utility-scale solar farms to reduce carbon emissions and increase energy independence. However, the expansion of these facilities raises concerns about competition for land for other uses, including biodiversity conservation. Thus, quantitative assessment of the friction between renewable energy development and conservation potential is an important step towards the sustainable development of the energy sector in this region. Here, grounded on land sparing/land sharing concepts, we discuss a prioritization framework based on solar potential and human footprint (used as a proxy for wilderness) to identify zones where the development of solar farms may cause a negative impact on biodiversity (sparing areas), and areas where they may have beneficial outcomes (sharing areas). We apply this framework to the Iberian Peninsula, where the land conflict may become particularly significant in the near future, given the high potential for photovoltaic production and expansion of photovoltaic installations, and the vast areas of well-preserved habitats still remaining. We detected around 18,000 km2 of sparing areas, of which half are not in protected areas, and >41,000 km2 of sharing areas. Much of these sharing areas are found near urban areas, which is where energy is most needed for supplying homes, transport, and machinery. Through strategic planning, the implementation of solar farms in land sharing areas has the potential to yield dual benefits, for both local biodiversity and food production, driving economic growth. By doing so, these initiatives can also safeguard important wilderness areas, which play a pivotal role in conserving biodiversity.
