Unveiling Agricultural Heritage: Mapping Historical Features in Farming Landscapes

ABSTRACT Agricultural heritage represents a unique fusion of natural and cultural elements, encompassing both tangible and intangible aspects that reflect the historical bond between humanity and the land focused on food production. Recognising its significance is vital, as it not only preserves tradition and expertise but also fosters sustainability and environmental resilience. While significant initiatives like Globally Important Agricultural Heritage Systems (GIAHS) are in place to safeguard remarkable agricultural areas with unique heritage values, frameworks for recognising the historic significance of non-outstanding agricultural areas are not sufficiently consolidated. Nonetheless, it is equally important to acknowledge the heritage value of agricultural systems that, while lacking exceptional features, succeed in preserving traditional techniques and processes, thereby conserving cultural landscapes and gastronomic identities. For this reason, this paper introduces a methodology for assessing the time depth of agricultural elements such as roads, livestock routes, agricultural plots, rural buildings and land use using historical cartography. By mapping historically significant features in farming areas, this method might be useful for recognising agricultural heritage and integrate it into spatial decision-making, ensuring the preservation of its cultural and environmental values. The method’s application is presented in a case study of Spain’s floodplains and irrigation areas near Aranjuez (Community of Madrid).

Rice sheath blight disease control by native endophytic Bacillus subtilis from Kuttanad, a Globally Important Agricultural Heritage System

ABSTRACT Kuttanad in India is known as ‘the rice bowl of Kerala’ and renowned for its unique rice cultivation system that is below sea level. However, rice production in this wetland ecosystem is seriously threatened by sheath blight disease caused by the fungus Rhizoctonia solani, which has resulted in a significant decline in grain quality and a 50% loss in yield. In the present study, we isolated two endophytic Bacillus subtilis strains, NIIST B616 and NIIST B627, from the roots of rice plants growing in the Kuttanad region and tested their efficacy in controlling sheath blight disease. We found that rice plants inoculated with a combination of both Bacillus strains and R. solani had a 64.71% lower disease incidence and a 31.02% higher harvest index than plants treated with R. solani alone. An analysis of defence-related enzymes and chemicals revealed that treatment with both isolates together greatly enhanced levels of l-phenylalanine ammonia-lyase (PAL; 2.8 fold), peroxidase (POX; 7.4 fold), polyphenol oxidase (PPO; 4.5 fold), and total phenol (8.5 fold) compared with plants treated solely with R. solani, indicating that these isolates significantly increased plant defence responses through induced systemic resistance (ISR), and this finding was validated through a split-root experiment. More detailed analysis using gas chromatography–tandem mass spectrometry (GC-MS/MS) and liquid chromatography–tandem mass spectrometry (LC-MS/MS) techniques revealed that cyclo-(Pro-Leu) and cyclo-(Pro-Phe) were the major components responsible for the antifungal properties of the two isolates and their capacity to trigger ISR in plants. Thus, the Bacillus strains and their metabolites may be deemed viable alternatives for controlling the prevalence of sheath blight disease in rice plants and augmenting rice production at unique locations such as Kuttanad.

Assessing current environmental conditions and climate change influences on Syngonanthus nitens (Bong.) Ruhland: an endemic species and economic resource for extractive communities as globally important agricultural heritage systems

Capim dourado, also known as sedinha, refers to the everlasting flower Syngonanthus nitens (Bong.) Ruhland (Eriocaulaceae), prized for its use in crafting and as a significant income source for communities in Minas Gerais, Bahia, and Tocantins, Brazil. This plant is also utilized in the creation of highly valued jewelry and accessories on the global market. This study aims to ascertain the thermal and humidity thresholds of S. nitens while mapping and predicting its current and future distribution. Initially, distribution data was gathered through a literature review, supplemented by biological temperature and humidity data collected from the Quilombola Raiz Community in Minas Gerais and a germination experiment conducted at the Integrated Multi-User Research Laboratory of the Jequitinhonha and Mucuri Valleys (LIPEMVALE). Climate Index (CLIMEX) parameters were defined using biological information and occurrence locations. The optimal temperature range for S. nitens development is between 18 and 24 °C, with minimum and maximum thresholds of 5 °C and 40 °C respectively. Ninety-two occurrence records were found, all situated in South America, aligning with high climate suitability regions as per the model predictions. Future projections for 2050 and 2100 indicate a decrease in areas suitable for S. nitens. These findings provide crucial insights for decision-making, necessitating measures such as widespread monitoring, collaborative conservation efforts, and the establishment of sustainable use zoning to manage S. nitens effectively.

In this study, the author compares the selection criteria and characteristics of the “Zhejiang Qingyuan Forest-Mushroom Co-cultivation System” with those of other World Agricultural Heritage sites. Through an in-depth analysis of the uniqueness of the “Zhejiang Qingyuan Forest-Mushroom Co-cultivation System” and its ecological, economic, and cultural values, the author aims to reveal its advantages in the World Heritage List and explore reasonable ways for its sustainable development.

Cardamom (Amomum tsaoko) agroforest is important habitat for skywalker hoolock gibbon (Hoolock tianxing) in Mt. Gaoligong, Yunnan, China

Understory plantation of cardamom (genus Amomum) is an ancient and widespread agroforestry practice in the eastern Himalayas and Southeast Asia, an area that supports high regional biodiversity. Cardamom provides an important cash income to rural people, and governments encourage cardamom cultivation as a replacement for slash-and-burn agriculture to alleviate poverty, aligning with the principles of the Globally Important Agricultural Heritage Systems (GIAHS) program initiated by the FAO. This program recognizes and supports traditional agricultural practices that contributes to biodiversity conservation and sustainable development. In this context, cardamom agroforestry not only supports local economies but also provides crucial habitat for animals, including the newly described skywalker hoolock gibbon (Hoolock tianxing). Nearly half of the remnant population of the skywalker hoolock gibbon lives in cardamom agroforest. In order to evaluate if gibbons could survive in cardamom agroforest for a relatively long term, we compared foraging behavior of gibbons over a year living in cardamom agroforests (group NA) and well-preserved forests (group BB) in Mt. Gaoligong, Yunnan, China. In response to habitat degradation caused by cardamom plantation, group NA increased feeding time and spent more time feeding on leaves. Notably, they consumed nuts of Castanopsis hystrix which is an unusual food type for gibbons. On the contrary, members of group BB rarely ate nuts though Castanopsis hystrix is abundant within its home range. However, group NA did not occupy a large home range, or travel longer in time or distance than group BB. We also monitored female reproduction of five groups for 5–13 years. Two adult females living in agroforests successfully reared two or three offspring with an inter-birth interval of five years. In addition, we surveyed group size of 16 groups (9 in agroforest vs. 7 in well preserved forests) from 2017 to 2023, and we found no significant difference in group size between habitats. Our results suggested that cardamom agroforest can sustain skywalker hoolock gibbons provided it is not too fragmented and hunting is prohibited.

Agro-Silvo-Pastoral Heritage Conservation and Valorization—A Comparative Analysis of the Chinese Nationally Important Agricultural Heritage Systems and of the Italian Register of Historical Rural Landscapes

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.

Unveiling Climate Trends and Future Projections in Southeastern Brazil: A Case Study of Brazil’s Historic Agricultural Heritage

The intricate relationship between climate and society in a given region demands a profound understanding of climate patterns, especially in agricultural areas like Diamantina, Minas Gerais (MG), recognized by the Food and Agriculture Organization (FAO) as the birthplace of the first Globally Important Agricultural Heritage System (GIAHS) in Brazil, situated in the southwest region of the country. Given the growing concerns about climate change, we conducted a meticulous analysis of the climatic characteristics of Diamantina-MG. To achieve this, we examined historical meteorological data from 1973 to 2022, employing the Mann–Kendall and Sen’s slope tests to analyze trends. Additionally, we utilized three global climate models (GCMs) under different shared socioeconomic pathways (SSPs) to predict future climate scenarios (2021–2100) based on the projections of the sixth phase of the Coupled Model Intercomparison Project (CMIP6). Furthermore, we used Köppen and Thornthwaite climate classification methodologies to characterize both the current and future climate conditions of the region. Our results indicate that, historically, Diamantina-MG has experienced significant increases in minimum temperature, indicating a warmer climate in recent decades. For temperature, the projections show a consensus among models, projecting a continuous increase, potentially reaching up to 5.8 °C above the historical average temperature (19.2 °C) by the end of the century. Regarding rainfall projections, they show greater uncertainty, with discrepancies among models observed until 2060. However, specifically for the second half of the century (2060–2100), the models agree that there will be increases in annual rainfall. Regarding the climatic types of the region, we found that the current Köppen Cwb and Thornthwaite B3rB’3a’ classifications could shift to Aw and B1wA’a’, representing a humid tropical savanna climate with longer periods of water deficiency, considering the impacts resulting from increased air temperature and evapotranspiration. In summary, the study’s results indicate that climate changes are occurring and are likely to intensify in the Jequitinhonha Valley region, MG, in the future. The analysis of these data, from the perspective of the Brazilian GIAHS sustainability, reveals the importance of considering adaptation and mitigation measures to ensure the resilience of agricultural systems and local communities in the region that face these significant environmental changes.

Review of the high bed–low ditch system as an alternative to lowland paddy in tropical and subtropical Asia

Many forms of traditional raised bed systems could be found around the world. Several of them have been identified as Globally Important Agricultural Heritage Systems (GIAHS) sites by Food and Agriculture Organization of the United Nations. Unlike traditional raised bed systems with similar structures in the Americas, the high bed–low ditch (HBLD) system in tropical and subtropical Asia, which is originated and developed from rice production, has been playing an important role in enhancing food security and maintaining farmer livelihood for centuries. Moreover, products provided by HBLD system are not only important for the livelihood of the local farmers, but also important for people living in the nearby towns and cities especially for vegetable and fruit supply. In this system, the ditches or sunken beds can be used to lower the groundwater table, retain nutrients and soil particles washed from the bed, grow rice or aquatic vegetables, and raise fish or shrimp. The HBLD system can also help to reduce salinity in coastal lowlands due to the presence of ditches. The raised beds can be used to grow various upland crops. Compared with rice monocropping, the adoption of HBLD system significantly improves the cropping intensity, productivity, employment, and income of farmers. Famers’ long-term practices fully demonstrate that this system is a type of sustainable agriculture with strong adaptability to the changes of natural environment. However, it should also be noted that the large-scale development of HBLD systems is not simply dependent on natural conditions, but is also determined by specific socioeconomic factors, such as good transportation facilities, a well market system, and a sufficient supply of labor. As a model of equilibrium between food production and high levels of biodiversity maintenance, the HBLD system is an important agricultural heritage system with global significance, and it should be well preserved and utilized in new ways to realize its important multiple functions under conditions of rapid urbanization in lowland and coastal regions.

Opportunities for China’s Agricultural Heritage Systems under the “Digital Nomadism” Trend—A Stakeholder-Weighted Approach

Agricultural heritage systems are appreciated worldwide for their significant environmental and cultural values. However, the sustainability of these systems has been compromised by environmental issues due to intensive human activities and socio-economic changes. Research has noticed that “digital nomadism” is providing a new opportunity for the sustainable development and transformation of these systems, regarded as “digital nomad-friendly” destinations. Nevertheless, comprehensive research on this new trend has been limited except for a few individual case studies. This study is the first to investigate the sustainable development of agricultural heritages considering the growing phenomenon of digital nomadism on a large scale. Based on in-depth stakeholder interviews, we introduced the Digital Nomad-Friendly (DNF) score—a comprehensive indicator system chosen and weighted by stakeholders. The DNF scores of 189 China National Important Agricultural Heritage System (China-NIAHS) sites were evaluated, and their distributions were analyzed on a national scale in China. The results highlight the importance of natural landscape and cultural value in the eyes of digital nomads, particularly emphasizing aesthetic landscape features, climatic suitability, and a community atmosphere. Sites with the highest DNF scores are located mostly in the Zhejiang and Yunnan provinces, sharing characteristics that appeal to digital nomads. The DNF scores exhibit regional variations, with high-DNF-score sites being concentrated in southwestern and southeastern China. By enhancing our understanding of digital nomads’ preferences and the influencing factors, this study provides valuable insights for the environmental management, policymaking, and sustainable development of China-NIAHS sites considering contemporary environmental and social changes.

What Is the Role of Public History and Environmental Oral History in Supporting Conservation through Agroecology?

Indigenous peoples and local communities are key actors in the preservation of important biodiversity resources around the world. However, the ever-encroaching agricultural frontier and expansion of conventional agricultural practices threaten these communities, their autonomy over the land, and the traditional knowledge and practices associated with biodiverse ecosystems. Agroecology emerges as an important solution to support the continuation of agrobiodiversity, food security, and environmental conservation, but top-down solutions often do not resonate with the lived realities of traditional, Indigenous, and small-scale farming communities. This paper examines a collaborative research and narrative network developed over the past several years around traditional erva-mate agroforestry production in Southern Paraná, Brazil. It offers an example of how oral environmental history and public history can support conservation practices through agroecology. The key outcomes of this interdisciplinary, multi-dimensional research and engagement were the development of a candidacy for the system to be recognized as a Globally Important Agricultural Heritage System (GIAHS) from the Food and Agricultural Organization of the United Nations (FAO) and the implementation of a Dynamic Conservation Action Plan to address the threats and challenges farmers and communities are facing. The discussion explores two concepts that were integral to these processes, the creation of narrative networks and a focus on plurivocity. Both approaches ensured that the actions, knowledge, and narratives developed through the GIAHS candidacy were not imposed but agreed upon and generative through narrative and dialogue, remaining true to the realities and lived experiences of community members.

Analyzing the policy-driven adaptation of Important Agriculture Heritage Systems to modernization from the resilience perspective: a case study of Qingtian Rice-Fish Culture System, China

Formulating effective conservation and management policies plays a key role in helping Important Agricultural Heritage Systems (IAHS) cope with the threats and challenges brought by modernization. An important criterion to measure their effectiveness is whether they maintain or enhance the resilience of IAHS. In this study, we first integrate IAHS resilience into the social-ecological systems (SES) framework and propose a SES-based analytical framework for IAHS resilience, which helps analyze how IAHS adapt to external disturbances under the drivers of policies. Then, we suggest the trade-off of ecosystem services as the surrogate of IAHS resilience and use the carbon footprint per unit output value as an indicator to quantify IAHS resilience. The application in Qingtian Rice-Fish Culture System (QRFCS) reveals that the rice-fish culture systems in three villages have formed different development models driven by different conservation and management policies when challenged by modernization, and have displayed different resilience in different development models. The development model centering on enlarged-scale fish farming in Xinpeng Village has shown the highest resilience; the development model with a combination of moderate-scale land management and experiential heritage tourism in Longxian Village has displayed a moderate resilience; and the development model with organic rice-fish culture integrated into terrace sightseeing tourism in Xiaozhoushan Village has shown the lowest resilience. Based on this, we put forward suggestions for maintaining and enhancing the resilience of QRFCS, so as to improve the management of the heritage system. We present that the results will not only enrich the resilience study of SES, but also promote IAHS management and regional sustainable development.

Transformación del patrimonio biocultural en el archipiélago de Chiloé: Un Sistema Importante del Patrimonio Agrícola Mundial*

Peasant family farming is characterized by its resilience to change, although it is exposed to drivers of socio-environmental transformation. We study the historical and contemporary drivers of change that have influenced the loss of biocultural heritage in the Rilán peninsula, a rural space in the Chiloe archipelago, in southern Chile that has been recognized by FAO as a Globally Important Agricultural Heritage System (GIAHS). Between September 2020 and October 2021, through a literature review, farm characterization sheets, and semi-structured interviews, eighteen family farms were visited, and individual conversations were held with a local historian and a rural extensionist in the agricultural field. The results show that, in the Chiloe archipelago, family farming continues to be a fundamental activity in terms of both identity and production, where, despite the changes in rural lifestyles in recent decades, a broad complex of knowledge, practices, and beliefs persists that have withstood rapid processes of agricultural modernization and multiple territorial transformations.

“Listen to us”: small-scale farmers’ understandings of social-ecological changes and their drivers in Important Agricultural Heritage Systems

Current social-ecological changes affect territories and people’s livelihoods worldwide. Many of these changes have detrimental effects on small-scale agricultural systems, with concomitant negative consequences on global and local food security and sovereignty. The objectives of this study were to explore (i) local knowledge on social-ecological changes and (ii) the perceived drivers of those changes occurring in a mountainscape and an islandscape in two Important Agricultural Heritage Systems of southern South America, both located within a Global Biodiversity Hotspot. This was done by conducting in-depth semi-structured interviews with local campesinos, whose livelihoods are based on the use and management of agrosilvopastoral systems. We found that local communities experience a wide range of globally and locally induced social-ecological changes acting in their territories. Campesinos mentioned 79 different observations of social-ecological changes and identified drivers for 77% of them. Changes in the atmospheric system, specifically regarding changes in precipitation, drought, and temperatures, were commonly observed by campesinos in both sites. Participants also observed complex interrelations between these changes and the drivers influencing them, climatic drivers being the most important. Even though general changes in climatic patterns were identified as drivers of changes by campesinos, other situated changes derived from the site’s biophysical, social, and economic conditions were also important. Our results highlight the importance of considering local knowledge to understand social-ecological changes and to support the development and implementation of public policies that promote contextualized adaptation measures to global changes that affect local livelihoods.

Re-Imagining Urban Wetlands: Watery heritage and food policies in the Albufera de València

Urban food policies require interdisciplinary research and action. Based on a holistic vision, these policies aim to facilitate the transformation of the food systems of cities in a sustainable, equitable and resilient manner. Food availability is key to urban food policies and involves recognition of the widespread disconnect between agriculture and consumers and the central role that food-related practices can play in the transition towards sustainable and resilient cities. This article addresses this topic by investigating the strategic role of one area of urban wetlands that has fostered new positive and shared attitudes towards watery heritage. The recovery of waterscapes in the Albufera, in close proximity to one of the most rapidly expanding Spanish urban areas, València, has allowed for a remarkable improvement of both traditional fisheries and paddy fields that has facilitated the regeneration of sustainable food practices. In 2019, the Horta de València, comprising a system of fields extending over a 28 km² area that is irrigated by the Túria River, was recognised by the United Nations Food and Agriculture Organisation (FAO) as a Globally Important Agricultural Heritage System (GIAHS). The area includes the historic Huerta and a section of the Albufera National Park that still maintains elements of traditional Arab heritage. The Albufera is thereby a significant repository of watery memories related to fisher people, peasants and sailors that an increasing number of environmentalists and seaside tourists interact with, and it thereby exemplifies the nature of wetlands as knowledge resources that can inspire sustainable food practices and policies.

Scientists and remaking heritage: the case of shiitake cultivation in a globally important agricultural heritage system in Japan

ABSTRACT A growing number of traditional agricultural systems around the world have been designated Globally Important Agricultural Heritage Systems (GIAHS), as they are exemplars of the accumulated wisdom of human communities and their close relationship with the local ecology. Heritage inscription is a strategy used to conserve and increase awareness of this inheritance. However, the role of scientists in the construction and inscription of the agricultural heritage has been understudied. Through a qualitative methodology and participatory-observation research, this study examines biocultural heritage construction in a GIAHS in the Kunisaki Peninsula of Oita, Japan. Drawing on actor-network theory and based on the experience of scientists who specialise in traditional log-cultivated shiitake farming, this study demonstrates the role of non-human actors – a fungus-covered chip and shiitake, in particular – in the heritagisation process and the role of scientists in stabilising and destabilising the heritage network. I find that the heritage inscription process of the tradition of log-cultivated shiitake farming has created a new form of identity and moral capital associated not only with the conservation of Japanese food and agricultural heritage but also with the continued existence of local rural villages, protection of national food security and global environmental health.

Assessing Food and Livelihood Security in Sea Salt Community: A GIAHS Study in Ban Laem, Phetchaburi, Thailand

This study investigates food and livelihood security in Ban Laem District, Phetchaburi, a unique sea salt community recognized under the Globally Important Agricultural Heritage Systems (GIAHS). We assess the current status of food and livelihood security, utilizing the entropy weight method. Our findings reveal a composite evaluation score of 2.724, comprising an average food security rating of 1.476 and a livelihood security score of 1.248. Agricultural diversity emerges as pivotal for food security, while financial support, indigenous knowledge preservation, and climate adaptation strategies are crucial for livelihood security. Our recommendations include fostering awareness, collaboration, diversified farming, financial accessibility, and cultural conservation initiatives. This research provides valuable insights into coastal community security and informs transformative policies for sustainable development.

Transcriptome analysis in gill reveals the adaptive mechanism of domesticated common carp to the high temperature in shallow rice paddies

Qingtian paddy field carp (PF-carp) is one of the core elements of the first Globally Important Agricultural Heritage System (GIAHS), Qingtian rice-fish coculture system, and might be the unique and most successful fish species domesticated under shallow rice paddy condition. It shows well adaptation to shallow water and high temperature in rice paddies. In order to reveal the mechanism of this kind of adaptation, we performed transcriptome sequencing and analyzed related enzyme activity indices in the gill tissues of PF-carp at different temperatures (28, 34 and 38 °C). A total of 2831 differentially expressed genes (DEGs) were identified by transcriptome sequencing analysis, and KEGG analysis revealed activation and involvement of DEGs in different pathways, including protein processing in endoplasmic reticulum, apoptosis and NF-κB signaling pathway. Among these pathways, key signaling factors such as HSP70, HSP90, gp78, Caspase 3, BAX, and IL-8 exhibited varying expression trends. Enzyme activity indicators showed no significant difference in CAT, GSH-Px and MDA at 34 °C and 38 °C within group. Our findings suggest that PF-carp primarily adapts to high temperature environment in rice paddies through the activation of protein processing in the endoplasmic reticulum to prevents protein misfolding and NF-κB signaling pathway activated by IL-8 and HIF-1β to enhance organism immunity, and the organism does not experience hypoxia and apoptosis when it is in high temperature environment. This study offers valuable insights into the adaptation mechanisms of this species to high temperature environments in rice paddies.
