“…In 2019, China accounted for 32.6% of the world's overall installed capacity of photovoltaic power, mainly thanks to regional and national policies carried out in the last decade. For example, Zhejiang province launched aggressive policies to support photovoltaic systems in the early 2010s, becoming the first province according to the cumulative installed capacity [50]. Despite some policies being specifically aimed at placing solar panels on the rooftop of houses (as the Million Households Project), and therefore minimizing the impacts on productive surfaces, our study demonstrated that the spread of solar panels in the area mainly occurred on agricultural surfaces.…”

Peri-urban traditional agroforestry systems are considered a priority at an international level, as they serve as a link connecting cities and rural areas, providing local food and ecosystem services for people living in the cities. The mulberry-dykes and fishponds system (MFS), located near Huzhou city (Zhejiang province, China), also has a key role in protecting the city from floods, as it developed as a consequence of the ancient flood control system created to protect local cities and villages from recurring floods. This system is recognized for its sustainability and for the strong functional interlinkages between the different components (mulberry trees, fishes, silkworms) by the Food and Agriculture Organization (FAO), which included it into the Globally Important Agricultural Heritage Systems (GIAHS) Programme in 2017. The research intends to measure landscape transformation in the last 12 years and to evaluate the effectiveness of the inclusion into the GIAHS Programme for land use changes mitigation. In addition, an accurate discussion focusing on the analysis of local planning has been done to evaluate its capacity in protecting and valorizing the site. Results demonstrated that MFS has undergone major land use changes in the last years due to urban sprawl, the spread of solar panels (+7% in 2018–2021), and abandonment of the traditional mulberry-based system (−75% in 2009–2021). Other changes are related to the overall number of traditional fishponds (−81% in 2009–2018 and −33% in 2018–2021) and to their shape and size. Local planning tools are too sectorial, not enough integrated one another, and they do not consider the MFS as a single system. The study demonstrated that the inclusion in the GIAHS Programme is not sufficient itself to stop negative trends in the absence of adequate planning tools, even if it can contribute to slowing them down, but it would be crucial to integrate the GIAHS action plan and vision into local planning tools.

“…Interesting views and lessons can be learned from those experiences and legislation. China has a challenge but also a great opportunity to become a world power in PV module recycling (7,29), involving the government, scientists, and stakeholders (30). In solar cells, silicon is the most widely metalloid used by several orders of magnitude and is irreplaceable in PV deployment, which demand could reach up to nearly 9% of the annual domestic production.…”

The target to achieve carbon neutrality is to enforce explosive growth of the global solar photovoltaic (PV) industry. This may involve severe resource constraints to meet their future metal demands. Herein, we consider different scenarios for the latest Chinese solar PV roadmaps and mature photovoltaic sub-technologies that may dominate. We estimate metal intensities, supply material risks, end-of-life photovoltaic modules, energy intensity, and costs associated with deploying PV panels and analyze dynamic processes from 2000 to 2060. Results show that the strength of metals varies widely between scenarios and dominant sub-technologies, ranging from 30% to 1300%. Annual supply pressures suggest metal demand will be challenging, peaking in 2040-2045. According to priorities, domestic production of gallium, tellurium, indium, selenium, and silver is likely in short supply in 2020, while production of aluminum, copper, tin, and silicon is under moderate supply pressure, suggesting that China could be at risk of missing out on its future PV roadmaps. To mitigate future demand for metals and assess future energy security, efforts should be made to implement regulations, policies, and investments in circular economy strategies.

Solar energy offers a clean and abundant alternative to the challenges associated with fossil fuels such as greenhouse gas emissions and resource depletion. The review focuses on the environmental impacts of solar photovoltaic technology throughout its life cycle, from manufacturing to disposal, and highlights potential hazards associated with using and producing photovoltaic technology, including releasing toxic gases and other trace elements into the environment. The paper concludes by summarizing various recycling techniques that can be employed to address these challenges and to take full advantage of solar photovoltaic technology without causing harm to the environment.
