Bioclimate and natural vegetation have a long - term relationship that identify the potential vegetation distribution at different areas. For that reason, bioclimatic classification system was applied to the territory of Ba and Kone river basin, Vietnam. The precipitation and temperature dataset of Ba and Kone river basin was collected from 17 climate, hydrology, rain gauge stations which allowed to create a bioclimatic map at a scale of 1:250.000. Three bioclimatic factors of thermal-moisture basic conditions such as annual temperature (TN), annual rainfall (RN), length of dry season (n) are selected as criteria system of Ba and Kone river basin’s bioclimate. In order to describe the relationships between bioclimatic variables and zonal vegetation units, the resulting map presented 12 bioclimatic units corresponding distribution of vegetation from low to high altitudes. By building bioclimatology map in Ba and Kone river basin, the government can develop sustainable agro forestry in Central Highlands and South Central Coast of Vietnam.

The chestnut tree is an important forestry species worldwide, as well as a valuable food resource. Over recent years, Portugal has shown an increasing trend in chestnut tree area, as well as increases in production, hinting at the socioeconomic relevance of this agro-forestry species. In this study, bioclimatic indices are applied to analyse the spatial distribution of chestnut trees in mainland Portugal, namely growing degree days (GDD; 1900–2400 °C), annual mean temperature (AMT; 8–15 °C), summer days with maximum temperature below 32 °C (NTX), and annual precipitation (PRE; 600–1600 mm). These indices are assessed for the baseline (IBERIA01, 1989–2005) and future climates (EURO-CORDEX: 2021–2040, 2041–2060, and 2061–2080) under two forcing pathways (RCP4.5 and RCP8.5), also taking into account the chestnut tree land cover. For the baseline, the GDD showed only 10% suitability for chestnut tree cultivation in southern Portugal, whereas much higher values are found in the north of the country, and at higher altitudes (50–90%). For the AMT, higher elevation areas in northern Portugal show almost 100% suitability. Concerning NTX, the suitability reduces from the west (100–90%) to the east (40%). Regarding PRE, the suitability is heterogeneous throughout the territory, with areas under 50%. A new Chestnut Suitability Index (CSI) was then computed, which incorporates information from the four previous indices. The CSI reveals a suitability ranging from 100 to 75% in the north, while central and southern Portugal show values from 25 to 50%. For future climates, a progressive reduction in CSI was found, particularly for RCP8.5 and in the long-term period. Changes in bioclimatic conditions may restrict the 100% suitability to a narrow area in the north of the country. These reductions in chestnut bioclimatic suitability may have socio-economic and ecological implications for the management of the important agro-forestry species.

Located in Central Africa, Cameroon is a country with strong social inequalities and fragile governance and institutions. This has a direct impact on the sustainable development of its territory, communities, and native forest, which are subject to constant socio-environmental and economic pressures due to overexploitation. This research has three purposes: (1) to conduct a comparative theoretical/empirical diagnosis on the quality of Cameroon’s institutional framework, governance, and public policies related to territorial sustainability; (2) to assess the impact of the three clusters identified among the 44 stakeholders interviewed (forestry companies/certifiers; NGOs/communities; and banks/public institutions) on each other; and (3) to analyze the contribution of the use of cassava (Manihot esculenta) as an agro alternative to Cameroon’s socio-ecological resilience, sustainable development, and conservation of native forests. The research found: (1) the need for mixed governance with joint accountability to find equitable and lasting sustainable solutions for the parties involved, making communities/ethnic groups visible in the decision-making process; and (2) the agro use of cassava has a positive impact on socio-ecological resilience by contributing to employment, the protection of devastated soils, and the provision of quality food, and by reducing pollution from the cement industry through using cassava waste as an input.

The 4.0 technologies are changing agricultural production processes and with them the agro-food supply chains, fundamental for the competitiveness of the Made in Italy and Basilicata, a region of southern Italy. It has invested in modernization and restructuring of agricultural, agri-food and forestry farms by rural development policies, which address respect for sustainability and to reduction of renewable and non-renewable resources, preserving quality and the link with the territory.   Some Lucanian agricultural entrepreneurs, interested in experimenting with innovative and sustainable agriculture, has intensified relations with the local scientific world, the advisors, training institutions and with small and medium-sized agro-industrial enterprises, setting up clusters. Then European Partnerships for Innovation have formed inside them.   This paper analyses the eleven Operational Groups of the Lucanian European Partnerships which represent the incubators for the digitalization of agri-food 4.0. From the analysis it emerged that the maximum expression of digitization in Basilicata is Precision Farming, as evidenced by the establishment of a specific operating group, AgrotechBasilicata. However, the other Lucanian OGs can also be classified as digital because they are interested by information collection systems, software and data analysis, as well as robotics and automation.

Farming and agro-industrial waste can represent a resource when destined to energy production and they can contribute to reduce greenhouse gas emission, to improve energetic efficiency and increase renewable energies. 6 stations are already working in Calabria for agro-zootechnical biomasses and agro-industrial waste transformation, in compliance with 91/676/CEE, Nitrates Directive, then D.L. 152/99 and D.M. 7 April 2006, redefined by D.M. 6-7-2012 It reduced incentives, with the aim of implementing small sized stations powered by recyclable byproducts, which are easier to manage especially in the form of consortium by medium and small sized companies that would otherwise be excluded from the market. An appropriate use of pruning waste would also mean turning a problem into an opportunity if, instead of burning it and producing high levels of CO2 (as forbidden by D.L. “terra dei fuochi”) it could be destined to produce a new kind of power source, biochar, with a carbon negative function. Concerning the market of carbon credits derivable from pruning waste and from the production of more than 130.000 t of biochar (which, differently from the forestry sector, hasn’t been accepted in farming yet), the potential wealth on the regional territory could vary from 5 to 11 million € according to the set price. Establishing a more competitive and sustainable source of energy is one of the most important challenges that our Country has to face today. This sector plays a key role in the economic development of the Country, not only as a distinctive feature of low cost energy production, limited impact on environment and high utilization, but also as an element of growth per se, with a boost in ecologic economy thanks to a predominant use of renewable resources, recycling and curbing domestic or industrial waste, according to Green Economy parameters.

The municipality of Serra, Valencia, located in the Spanish Mediterranean east coast, covers an area of 5,730 hectares, with 95% of this territory lying within the Sierra Calderona Natural Park and 85% being forest. The main axis of the municipality’s economy has been the construction, reducing the primary sector, resulting in uncontrolled growth of forest and deterioration of the landscape. All this has raised forest fire risk to dangerous levels threatening the natural heritage of Serra and the future of the Serra Calderona Natural Park. The study shows how an adequate model of forest biomass management, through energetic use in sustainable public heating systems, can have positive direct effects in the fight against climate change, considering both economics aspects and environmental effects, and its capacity to contribute to the socioeconomic development of agro forestry regions, fixing its habitants and offering a rural development based on the rational use of their natural resources

The south of Russia is the largest agro-industrial region of the country. One of the factors contributing to the successful development of agriculture in this area are the stable agroforestlandscapes, formed several decades ago, the main structural element of agroforestlandscapes are forest shelterbelts, which exert meliorative influence on the agroecological situation in the agrolandscapes. However, as a result of the impact of natural-climatic and anthropogenic factors, most of the protective forest plantations are in an unsatisfactory state. In this regard, it is necessary to carry out an inventory of the forest reclamation fund to obtain reliable information on their quantity and current state of protective forest plantations, with a view to developing urgent forest measures aimed at preserving them, improving the forest and reclamation condition and increasing they longevity. At present, information technologies are widely used in scientific research and practical activities, including agriculture and forestry. However, the use of remote methods and geoinformation technologies in the study of protective forest stands from the point of view of a systematic approach (assessment of forest strip systems in agrolandscapes), both in domestic and in foreign scientific research, is not sufficiently developed and requires further study. The developed author's method of agroforest reclamation assessment of protective forest plantations on the basis of remote information and GIS technologies allows simultaneous carry out three-level analysis of forest belt systems within the administrative area, the farm and the individual forest strip. The proposed approach opens up new opportunities for conducting research in the assessment of the state of protective forest plantations of the territory of the Russian Federation for the development of scientifically based principles and methods for the rational management of the agroforest reclamation fund. The presented method was successfully implemented during monitoring of protective forest plantations on the territory of the Krasnodar Territory within the framework of the implementation of the regional target program "Fertility" for 2006-2010, on an area of more than 11,000 hectares.

The article presents data on the current topic of conservation and reproduction of oak forests in the arid conditions of the Lower Volga region on various relief elements. The article contains the result of long-term studies of oak forests of the Lower Volga region, the main predominant species of which is the petiolate oak (Quercusrobur L.). It was found that on soils of the Lower Volga region poor in humus composition with dissected relief and difficult weather conditions, the plantations of the petiolate oak fully justified themselves. It was revealed that oaks have good growth on chestnut, light chestnut and chernozem soils, and moderate on sandy, biologically stable, moreover, species with a high content of chlorophyll show the best performance. It was determined that the most effective way to create oak forests is to exclude 25-40% of the parent trees that showed the worst results during research. Otherwise, the plantings may face a decline in radial growth, loss of part of the crown and often shrinkage. Рurpose of the research. Bio-ecological assessment of species of the genus Quercus, aspects of the formation of oak forests on uplands and flat landscapes for afforestation in arid conditions of the south of the European territory of Russia. The object of research was the plantings of the pedunculate oak (Quercusrobur L.), which has an extensive range. Observations were carried out in the Volgograd region in the arboretum collections of the Federal Research Center of Agro-ecology of the Russian Academy of Sciences, at the Shemyakinskaya dacha – the oak grove of the Uryupinsky forestry, geographical oak cultures in the Oktyabrsky forestry, genetic and breeding complexes of oak in the Novoanninsky forestry, in the Rossoshansky forestry of the Voronezh region, the system of protective forest plantations in the Bogdinsky forestry of the Astrakhan region and the Elistinsky forestry of the Republic of Kalmykia. Research methodology. The water content in oak leaves was determined by the weight method by the hour during the day (1 h, 2 h, 3 h, 4 h, 5 h, 6 h, 12 h, 24 h). Weather conditions and oak habitats were studied using the sites "Climate monitor" and "Agroatlas". The typology of forest growing conditions within the ALMR was characterized taking into account the forest suitability of soils developed by VNIALMI (now the Federal Research Centre for Agro-ecology, Complex Reclamation and Protective Afforestation). Based on the analysis of the results of all experimental materials, an integral indicator of the frost resistance of prototypes and control was calculated. Individual indicators of reproductive processes of clones were compared with the characteristics of control trees, revealing their correlations. The chlorophyll content was measured using the MS-100 device. Statistical data processing was carried out in the programs Statistica and Fractan. Research results and discussion. The intensity of growth of this species is determined by the geographical environment and the conditions of the place of growth. According to the results of the research, the petiolate oak showed excellent ecological and geographical plasticity and the ability to grow and develop in various conditions – from fine-grained leached sands of the Astrakhan and Elista experimental stations to light chestnut and dark chestnut soils of the Volgograd region, chernozem soils of the Novoanninsky and Uryupinsky forestry. The best growth and development were distinguished by the plants of the petiolate oak in conditions of macro-subsidence with dark-colored humus soils. A high percentage of oak trees with good condition were noted by the authors on micropropagations, meadow-chestnut slightly saline soils. There were no oak trees in good condition on flat, settled areas with the presence of saline spots. In the southern part of the Lower Volga region (Elista), oak forests with an age of 30 years or more are in poor condition, characterized by low growth rates and trunk diameter. In the Kamyshinsky arboretum, the annual growth of oaks decreases with increasing age, but the plants are characterized by the best resistance to high summer and low winter air temperatures, undemanding to soil conditions. Conclusion. Oaks of 30 years of age have good characteristics in the Novoanninsky forestry, which belongs to the moderately arid zone and is distinguished by chernozem soils. The upland ecotype prevails in this zone (85 %), the floodplain ecotype has the largest crown projection, an increase of 25 cm is observed in the oak ecotype of this zone, which determines the requirements for the soil and climatic conditions of the introduction regions.

An integrated geoecological approach to the optimization of the landscape-ecological organization of the territory (LEOT) of the Ternopil region, which is focused on determining the priorities and criteria of optimality in modern ecological-social-economic conditions, is considered. The features of the geoecological situation, as well as the natural resource potential of the region, are taken into account. A SWOT analysis of the objective prerequisites and subjective factors of the landscape-ecological organization of the territory has been carried out and the need for its implementation has been brought to light. Based on the materials of the development of economic spheres of the region, a comparative analysis of the existing development with optimal guidelines is carried out. The priority priorities in the modern conditions of the complication of the ecological situation - anthropoecological and environmental protection are not targeted and are considered in most projects and regional programs as secondary and are planned in the old-fashioned way behind a residual principle. The prospects for the development of agro-industrial are considered. water, recreational and forestry sectors of the economy as priorities for the existing in the region structure of production natural resource potential. Particular attention is paid to the formation and development of 12 promising regional landscape parks, the creation of which was proposed more than 15 years ago. Their creation with additions of environmental authorities is planned for all landscape areas of the region, including new administrative areas. In the tables below. describes the territorial structure, and their location, as well as the planned year of creation. An assessment of their role in recreational nature management was carried out, which made it possible to determine the stage by stage of their creation. In addition, this will provide an opportunity to optimize nature conservation management - to act as natural cores and eco-corridors of the regional eco-network. A schematic map has been created that takes into account the accessibility of the RLP and NPP of the region for recreants (Fig. 1) on which the entire territory of the region and significant parts of the neighboring regions are covered by the radius of visitor accessibility. Taking into account transport accessibility, this will make it possible to determine the spatial directions of creating and improving the existing recreational infrastructure, the formation and development of new elements of the territorial recreational system. The analysis of the existing ecological-geographical situation (EGS) in the locations of the proposed RLP was carried out and a conclusion was made about the prospective improvement of the natural conditions of the local population's life in the need for the creation of the three most functionally and infrastructurally developed RLP Berezhanskoe Opolye, Sredneseretskiy and Knyazhiy forest. The system of the considered proposals will make it possible to strengthen the resource-saving spheres of the economic complex, to balance the ecological-socio-economic development of the regional region and the participating local communities in the interests of the people. Key words: LEOT, SWOT analysis, optimization, balanced development, living conditions.

The agro-ecological farming has got started by social movements in favor to the rural sustainable development based on environmental, social and economic. Agroecologyis presented as an alternative to modernization of agriculture that repair environmental damage and social damage caused by the green revolution technology disseminated and adopted by the Brazilian government as a development policy based on the economic growth. This paper aims to analyze the agro-ecology alternatively forward the modernization process of the agriculture and the different territorialities provided by the two forms of production, as well as identify the limits and difficulties of territorial agro-ecological practices in Coronel Vivida, held bibliographic review the topic addressed and fieldwork, using a questionnaire addressed to eleven farmers who have comprised three distinct groups related to agro-ecology in the town: Farmers Convention with SAFs; 2) Agro-ecological Farmers; 3) Farmers Convention-Former Agro-ecological Farmers. And interviews with representatives of institutions related to agriculture and agroecology family whose work is in the town. The study of these three groups with different production and commercial organizations had allowed us to observe the process of territorialization and deterritorialization of simultaneous agro-ecological practices, the latter prevails. Another methodology used to characterize the properties sustainable, based on agro-ecological principles, as well as differentiate the analysis was made landscapes through sketches and photographs of the properties studied. This paper outlines the main difficulties faced by the town farmers relationed to agro-ecological production, as well as the main factors which have influenced the abandonment of agro-ecological practices by the Coronel Vivida agro-ecological farmers.
A agricultura agroecológica surge de movimentos sociais em favor de um desenvolvimento rural sustentável, baseado nas condições ambientais, sociais e econômicas. A Agroecologia é apresentada como alternativa a modernização da agricultura visando reparar os danos ambientais e prejuízos sociais causados pela tecnologia disseminada pela revolução verde e adotada pelo Estado brasileiro como política desenvolvimentista baseada no crescimento econômico. Com o objetivo de analisar a Agroecologia como alternativa frente ao processo de modernização da agricultura e as diferentes territorialidades proporcionadas pelas duas formas de produção, assim como, identificar os limites e dificuldades de territorialização das práticas agroecológicas em Coronel Vivida, realizou-se revisão bibliográfica sobre o tema abordado e trabalho de campo, com aplicação de questionário dirigido à onze agricultores familiares que compõem três grupos distintos relacionados com a Agroecologia no município: 1) Agricultores Convencionais com SAFs; 2)Agricultores Agroecológicos; 3)Agricultores Convencionais Ex-Agricultores Agroecológicos. E entrevistas com representantes de instituições ligadas a agricultura familiar e a Agroecologia que atuam no município. O estudo desses três grupos que apresentaram organizações produtivas e comerciais diferentes nos permitiu constatar o processo de territorialização e desterritorialização simultâneas das práticas agroecológicas, prevalecendo esse último. Outra metodologia utilizada para caracterizar os estabelecimentos sustentáveis, baseados nos princípios agroecológicos, assim como, diferenciar as paisagens constituídas foi à análise através de croquis e fotografias dos estabelecimentos em estudo. O presente texto aponta as principais dificuldades enfrentadas pelos agricultores do município em relação à produção agroecológica, assim como, os principais fatores que influenciaram no abandono de práticas agroecológicas por parte dos ex-agricultores agroecológicos de Coronel Vivida.

Cultural ecosystem services (CESs) are a particular type of intangible benefits that derive from ecosystems and contribute to human well-being. Due to their intangibility, the evaluation of CESs is particularly challenging. Therefore, this is a topic that can be further explored in the current literature. On the one hand, there is no real market for these services to easily estimate their monetary value; on the other hand, their intangible effects make investigations very complex. The research project comes from the idea of developing a support model for the public administration, in order to provide a useful tool to highlight the potential and resources provided by the territory. The purpose of this thesis is to explore different methods for the assessment of CESs: quantitative models for an economic estimation; and qualitative models for the study of contents related to the use of CESs. Within the category of CESs, the tourist-recreational function for outdoor activities was selected as the object of study, with particular reference to the agro-forestry area. This function has been declined according to two specific thematic strands in the field of outdoor recreational activities: the recreational hunting function; the visit to the protected areas. For the first research line, the territory of the province of Siena in Tuscany (Italy) was chosen as the study area. The choice to develop part of the investigation in Tuscany is firstly due to the fact that in this region hunting is very relevant as a recreational activity. Secondly, the regional administration is promoting both: a sustainable hunting model to help manage the high load of ungulates that has negatively impacted on agricultural and forestry productions; and a slow tourism policy to reduce the tourist flow to the big cities, creating new job opportunities in the rural area thanks to the enhancement of CESs. In this perspective, the Tuscan territory will be transformed into a tourist product, where the evaluation of CESs can represent a useful tool for combining territorial development and protection. The model for the economic assessment of the recreational hunting function was developed in the following steps. Initially, a series of meetings were held with local and national sector associations and regional administration offices responsible for the management of hunting activity. Sector associations and regional offices collaborated to: develop a questionnaire to determine hunting habits; and disclose the survey through their social channels. The investigation was addressed to all hunters resident in Tuscany, who during the 2018-2019 hunting season had hunted in the province of Siena. In the next step, based on the data collected, the hunters’ consumer surplus was estimated using the travel cost method. In addition, a detailed analysis of the annual expenditures for hunting activities was performed. The findings show that hunting has now become an elitist and almost exclusively recreational activity, and that it is no longer seen as an income supplement for rural communities. Moreover, by economic estimation of the recreational hunting function, the financial importance of this type of CES can be easily communicated to non-experts. Indeed, it has been found that the annual recreational hunting value for the entire territory of Tuscany is approximately between a minimum of EUR 68 million and a maximum of EUR 170 million. This value far exceeds that of the current Tuscan forest production, which is around EUR 25 million each years. In conclusion, knowledge of the economic value of CESs provides an essential foundation for planning effective management and development policies for the local territory. As regards the second research line, i.e. visit to protected areas, the Plitvice Lakes National Park (Croatia) was chosen as the study area. The Plitvice Lakes National Park is one of the most important naturalistic areas for international flows in Central Europe. At the same time, it is attracting increasing interest from the local population. The aim of the research project was to develop a flexible methodology for the analysis of the demanding management of protected areas, taking into account the perspective of visitors. The main reason for this complexity lies in the trade-off that exists between conserving natural ecosystems and promoting tourist visits for economic reasons. Methodologically, a complex system of several tools was implemented. First of all, TripAdvisor reviews on “Plitvice Lakes National Park” were scraped. Second, a sentiment analysis was performed, assigning each review a score. After that, a rapid automatic keyword extraction (i.e. a particular type of natural language processing procedure) was applied to extrapolate the main keywords from the reviews. Based on former results, the analysis of definitely positive and decidedly negative reviews made it possible to identify strengths and weaknesses of the tourist destination studied on the basis of visitors’ opinion. In parallel, the multidimensional scaling method and cluster analysis were used to explore potential combinations or groups of words that share similar schemes of appearance. In this way, it was possible to derive the main elements perceived by the reviewers that should be considered for an effective and rational management of the protected areas. Based on previous results, it is clear that visitors are especially sensitive to management aspects. For this reason, an online questionnaire was designed to determine how visitors perceive certain topics related to the theme of the visit system. In the survey, visitors were invited to indicate their level of priority on a variety of management issues. Subsequently, the results achieved were compared to the priorities assigned by the managers in the current Plitvice Lakes National Park Management Plan 2019-2028. The findings of the study proved that visitors to nature-based destinations are interested in discussing and contributing to the management of these places, and not only to appreciate the natural landscapes and beauties. Consequently, it seemed appropriate to involve visitors as protected area stakeholders to obtain their views on management issues. Briefly, social media data analysis combined with online questionnaires for visitors proved to be a comprehensive survey method. This methodology has made it possible to collect useful and practical information for those involved in the management and planning of protected natural areas. In conclusion, this thesis sought to explore a variety of quantitative and qualitative methods for assessing recreational functions within the CES category. Actually, a combination of qualitative and quantitative analysis would lead to building a more accurate framework for CESs. Furthermore, relying on different sources of investigation, a solid foundation of knowledge can simplify and improve the efficiency of natural heritage management, taking human activities into account as well. For this reason, it is essential that those who manage the natural resources linked to CESs invest in preliminary studies, in order to make effective investment and planning efforts.
