Landscape restoration projects are among the most extensive conservation actions at the global level that have been promoted in the last three decades. Such projects, however, cannot exclusively be based on the restoration of natural and semi-natural ecosystems, but should focus on a cultural landscape approach balancing environmental and socio-economic needs. One of the largest restoration projects realized in the last five years was the World Bank’s Burundi Landscape Restoration and Resilience Project (PRRPB). PRRPB utilized an integrated approach to restore the social-ecological systems in different steep-slope areas of Burundi, adopting a mix of landscape restoration solutions (slow-forming terraces, reforestation, etc.) and socio-economic measures. With a large-sample questionnaire, realized on the field with the local population, the following work aimed at assessing the impact, at the local level, of one of the largest landscape restoration projects carried out in a fragile region like Burundian sloping lands. The most perceived vulnerabilities were “Soil erosion and degradation” followed by "Reduction of agricultural production and/or food security”. Most of the interviewed perceived that the project was successful in combating soil erosion as well as in providing other benefits to the local population, and around 60% perceived an improvement in socio-economic conditions. At the same time, results assessed the high reliance of the local food security on traditional agricultural production and the possible positive/negative impacts of rural tourism as perceived by local communities. Project results could be used by local and national stakeholders to implement further initiatives at the local level and will be informative for similar projects in the region.

Context The study of landscape over different years through the analysis of different sources (cadasters, aerophotos, orthophotos, satellite images) is commonly used in landscape planning and in researches focusing on landscape and land use changes and transformations. Most of these studies, despite the scale and the period analyzed, tend to apply different methodologies, making it difficult to compare results and trends among different landscapes. The aim of the paper is to present the details of the Historical and Environmental Evaluation (VASA) methodology, highlighting the possible applications for landscape changes assessment, by presenting a specific study case as well as its use across different situations. VASA has been developed within the Department of Agricultural, Food, Environmental and Forestry Science and Technology (DAGRI) of the University of Florence to create a standard methodology for the monitoring of landscape transformations, and it was initially applied for the Regional Government of Tuscany (Italy). In 2012, VASA has been chosen by the Italian Ministry of Agriculture, Food Sovereignty and Forests for the assessment of the rural landscapes to be included in the official list of the National Register of Rural Landscapes of Historical Interest often representing the first step for rural landscapes to be proposed for the recognition by international programmes such as the UNESCO WHL (cultural landscapes) and the FAO GIAHS (Globally Important Agricultural Heritage Systems). Results This methodology is based on the photointerpretation of the same area in different years through the Geographic Information Systems (GIS) software, for creating detailed maps and databases of land uses. In addition, various metrics are calculated for evaluating the structure of the landscape mosaic and its transformations. Conclusions Compared to other multitemporal analyses, the VASA methodology is capable of providing reliable, measurable, and comparable data regarding land use characteristics, land use changes, landscape mosaic structure, main vulnerabilities, landscape trends, linear features presence and changes. This approach can be applied to different geographical contexts and for different aims, allowing to compare the results more accurately in different environmental and cultural situations, or for establishing landscape monitoring systems.

In this perspective, we present and discuss four major causes of the worldwide nature conservation failure: 1) ideologies based on nature–culture dualism, 2) the bias prioritising forests in conservation, 3) the illusory objectiveness of selected biological indicators, and 4) the mismanagement of rural agricultural landscapes. All of these relate to ignorance of historical ecology and neglect of the role past plays in shaping landscapes and fostering biodiversity. These led to a false anthropology focussed on the broader human economy (including agriculture) as the absolute culprit of biodiversity loss. It is believed, therefore, that biodiversity preservation depends on conservation policies and actions providing protection against human activities, such as farming. In this way, nature conservation has been detached from the rich experiences of long and fruitful coexistence of people with other elements of nature. The bio-cultural legacy includes biodiversity-rich rural landscapes, whose habitats are often either neglected or wrongly interpreted as “remnants of natural ecosystems”. Consequently, conservation efforts are frequently ineffective or worse still, counter-effective. In the face of policies favouring subsidised intensive agribusiness at the cost of destroying smallholder family farming, even expensive conservation projects are usually nothing more than a “fig leaf” to cover failure. We advocate re-focussing of conservation planning to put more emphasis on landscapes’ historical ecology responsible for their bio-cultural diversity. It implies the need for new principles in policies necessary to secure the economic and cultural sovereignty of local socio-ecological systems responsible for the world’s bio-cultural diversity.

The "Prosecco Hills of Conegliano and Valdobbiadene" has been inscribed in the UNESCO World Heritage List since 2019 under the category "cultural landscapes". The study analysed land use and landscape changes in the last six decades through spatial analyses and landscape metrics, identifying main changes and comparing similarities and differences between the Core and the Buffer Zone. The main aims were to identify the main drivers that contributed to the preservation of the traditional cultural landscape and to provide data and indications for landscape planning and conservation, with particular attention to the opportunities/threats due to the expected increase of tourism resulting from the recent UNESCO recognition. The study was conducted in the framework of the UNESCO site Management Plan. Results demonstrated that the Core Zone traditional landscape has a higher level of integrity compared to the Buffer Zone, due to the different terrain morphology that represents the main driver. The rough morphology of the Core Zone contributed to the preservation of traditional vineyards interspersed with small woods, linear tree formations and forest patches, as it was not possible to introduce mechanisation in viticulture due to steep slopes that oblige farmers to cultivate vines on ciglioni (earth terraces). Core Zone's main change was due to forestation (21% of the surface) on steeper slopes and higher altitudes, caused by the abandonment of pastures that occurred in the last decades. The main transformations in the Buffer Zone were agricultural intensification (29% of the surface) due to the replacement of traditional mixed crops, meadows, and arable land with modern and mechanised vineyards, and urban sprawl (average rate of 10 ha/year). The study highlighted that despite land use changes the Buffer Zone still contributes to the conservation of the overall UNESCO site landscape quality. Buffer Zone can also have a potential key-role in mitigating the increasing tourist flows, but additional urban sprawl or the spread of other modern vineyards should be avoided. The main long-term objective should be the preservation of the cultural landscape and the peaceful coexistence of farmers, local population and tourists, with mutual benefits, by applying a participatory approach.

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.

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.

Inle Lake, originally a tectonic lake, underwent a transformation during the Tertiary Period (1.6–65 million years ago) to become a solution lake. The lake was named after the first four villages (Nanpan, Ywagyi Banpon, Naung Taw, and Heya Ywama) that were located in the surrounding area.

Jessour are the oldest traditional system of Tunisian runoff collection and recovery, historically used for the cultivation of olive, fig, and date trees (Calianno et al., Water 12:295, 2020) that is mainly found in the mountainous areas of the watershed.

Coffee culture plays a significant role in shaping agriculture in the Sierra del Rosario mountains today. The presence of coffee crops is closely tied to the agrobiodiversity of the region, which has historical roots.
