Cinque Terre, one of the most important Italian cultural landscapes, has not been spared from depopulation and agricultural abandonment processes, that involved many rural areas in Europe, as a consequence of socio-economic transformations that occurred after WWII. Depopulation of rural areas, especially in mountains or in terraced areas, caused significant environmental consequences, such as the decrease of biodiversity, the landscape homogenization, the increase of hydrogeological and forest fires risks. Cinque Terre National Park (5TNP) was established in 1999, and, differently from other Italian National Parks, not just for protecting natural habitats, but mainly to preserve, restore and valorize the historical terraced landscape. Moreover, the area is a UNESCO cultural landscape site and it is partly protected by three Sites of Community Importance. The research intended to investigate the transformations that have affected forested areas inside the 5TNP in the period 1936–2018, also highlighting the connections with hydrogeological and forest fires risks, as a support for the Park planning strategies and the conservation of the UNESCO site. Results highlighted that 37% of the current forests are the consequence of dry stones terraces abandonment that occurred in the twentieth century, with negative effects on the stability of steep slopes, hydrogeological risk, forest fires and on the conservation of a unique cultural landscape. This confirms the current national trend showing no deforestation occurring, but rather a continuous increase of forests on abandoned land. While 5TNP policies and actions are effectively aimed at pursuing an equilibrium between cultivated areas and forests, the Sites of Community Importance located inside the Park mainly focuses on the conservation of “natural habitats”, even if the current vegetation is also the result of secondary successions on former cultivated land. The research highlighted the need to valorize “cultural values” in forest planning as well as the importance of forest history for an accurate planning of forest resources in protected areas.

The landscape is considered a strategic asset by the Tuscan regional government, also for its economic role, meaning that a specific Landscape Plan has been developed, dividing the region into 20 Landscape Units and representing the main planning instrument at the regional level. Following the aims of the Landscape Plan and the guidelines of the European Landscape Convention, it is necessary to develop an adequate assessment of the landscape, evaluating the main typologies and their characteristics. The aim of this research is to carry out an assessment of the landscape diversity in Tuscany based on 20 study areas, analyzing land uses and landscape mosaic structures through the application of landscape metrics: number of land uses, mean patch size (MPS), Hill’s diversity number, edge density (ED), patch density (PD), land use diversity (LUD). The results highlight a correlation between the landscape typologies (forest, agricultural, mixed, periurban) and the complexity of the landscape structure, especially in relation to MPS and PD, while the combination of PD and LUD calculated on the basis of a hexagonal grid allows obtaining landscape complexity maps. Despite the phenomena of reforestation and urban sprawl of recent decades, Tuscany still preserves different landscape typologies characterized by a good level of complexity. This is particularly evident in mixed landscapes, while agricultural landscapes have a larger variability because of different historical land organization forms. The methodology applied in this study provided a large amount of data about land uses and the landscape mosaic structure and complexity and proved to be effective in assessing the landscape structure and in creating a database that can represent a baseline for future monitoring.

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.

Protected areas have a key role in preserving biodiversity at different scales, as well as in providing ecosystem services to rural communities. Natura 2000 is the primary conservation network at the EU level, with the aim of protecting the most valuable species and habitats; it covers around 18.6% of the EU’s land area. The aim of this study is to assess the evolution of forest cover in EU Natura 2000 sites in the period 2012–2018 through GIS-based spatial analyses of the High-Resolution Layers produced in the framework of the Copernicus initiative. In 2018, fifteen EU countries had more than 50% of their surface covered by forests, with the top three countries being Slovenia (71.9%), the Czech Republic (70.5%), and Slovakia (69.3%). In 2012–2018, the net forest cover increase in EU Natura 2000 areas was equal to 105,750 ha/year (+1.7%). France, Bulgaria, and Germany recorded the greater net forest cover increase: 303,000 ha, 267,000 ha, and 150,000, respectively. France also recorded the highest yearly rate of forest gain (+51,491 ha/year). Most of the forest gain in EU Natura 2000 areas was found to be located between 0 and 200 m a.s.l. The study demonstrated that forest cover in EU Natura 2000 areas is increasing, with a consequent reduction of open spaces, homogenization of rural landscapes, and loss of landscape-scale biodiversity. The management and design of EU protected areas should consider the importance of preserving biodiversity-friendly land uses and practices, instead of promoting a diffuse “rewilding” with negative consequences for the landscape complexity and heterogeneity, as well as for biodiversity.

Agricultural heritage systems are receiving increasing attention due to their multifunctional role, their capability to provide ecosystem services, and for representing sustainable development models for rural areas. At the international level, the Food and Agriculture Organization (FAO) of the United Nations launched in 2002 the Globally Important Agricultural Heritage Systems (GIAHS) Program to identify and safeguard traditional agro-silvo-pastoral systems that are the result of the adaptation of rural communities to the surrounding environments. Following this approach, similar national programs have been developed, among which the Italian National Register of Historical Rural Landscapes and the China Nationally Important Agricultural Heritage Systems (China-NIAHS) initiative stand out. This research compares the China-NIAHS initiative and the Italian Register of Historical Rural Landscapes, highlighting similarities and differences and identifying strengths and weaknesses, to contribute to the development of proper tools for the conservation and valorization of agricultural heritage systems. Both initiatives were established in 2012 and share similar aims and inscription criteria, including historical and current significance, knowledge system and social structure, economic and productive framework, and causes of vulnerability. The main differences are related to the delimitation of the boundaries of the proposed sites and to the inscription process; in addition, while for the Italian National Register spatial analyses of land-use changes and landscape structure are mandatory according to a precise methodology, for the China-NIAHS no specific landscape analyses are required. The main critical issues are the lack of public participation and the lack of a monitoring plan after the inscription. The absence of monitoring is also the main vulnerability of the FAO GIAHS Programme. This research can offer important information for different stakeholders at the international, national, and local levels dealing with agricultural heritage conservation and valorization. In particular, it highlights the need of developing a multidisciplinary monitoring system with a standard methodology based on different indicators that can contribute to maximizing the impact of these initiatives. This research also provides useful information for the countries that are interested in developing a national initiative for agricultural heritage systems’ identification and valorization/conservation or for countries that intend to improve their national programs.

Small woods, linear tree formations, or scattered trees in agricultural areas are receiving increasing attention for their multifunctional role, especially if associated to cultural landscapes. Osaki Kodo’s Traditional Water Management System for Sustainable Paddy Agriculture represents one of the most important cultural landscapes (satoyama) of Japan, also included by the FAO in the GIAHS (Globally Important Agricultural Heritage Systems) Programme. Here, local farmers surrounded their farmhouses with small woods, called igune, as a protection from the cold winter wind, creating a peculiar landscape characterized by an intensively cultivated plain dotted with small wood patches. The research aims at deepening the knowledge of igune, evaluating the landscape role and monitoring their changes in the last 20 years, through multitemporal and spatial analyses. In addition, a literature review has been performed to assess other Ecosystem Services (ESs) provided by igune within the study area. Despite the limited overall surface, 1737 igune and small woods currently characterize the area, with 72% of them having a surface smaller than 0.5 hectares. The multitemporal and spatial analyses show that their number, distribution, and spatial pattern remained almost completely unchanged in the last 20 years, testifying their key role in characterizing the local cultural landscape. Least-Cost Path analysis highlighted a crucial role in connecting the two forest nodes of the region, as 90% of the path passes inside more than 70 different igune and small woods. Literature review demonstrated that igune and other small woods still provide various ESs, including ecological network, habitat for various flora and fauna species, firewood, and byproducts, as well as cultural services. This maintenance of the traditional management in cultural forests is crucial not only to retain their landscape role, but mostly for the preservation of the related ESs, as changes in the management can lead to changes in horizontal and vertical structures, and in species composition.
