Though considered an agricultural country, the Philippines is the world’s largest importer of rice. The persistent problem of insufficient rice supply, however, has been exacerbated by economic crises and natural calamities. Yet, for the Higaonon tribe in Bukidnon Province, the Philippines, the rich agrobiodiversity and wild edible plants are vital for food security and resilience since the mountainous terrain in this province presents a challenge for rice cultivation. To gain insight from the indigenous edible plant knowledge of the Higaonon tribe, we conducted an ethnobotanical research to document the diversity, utilization, and biocultural refugia of both cultivated and wild edible plants. A total of 76 edible plant species belonging to 62 genera and 36 botanical families were documented. The most represented botanical families included the Fabaceae, Solanaceae, and Zingiberaceae. In terms of dietary usage, 3 species were categorized as cereals; 8 species were white roots, tubers, and plantains; 3 species were vitamin A-rich vegetables and tubers; 16 species were green leafy vegetables; 12 species were categorized as other vegetables; 2 species were vitamin A-rich fruits; 27 species were classified as other fruits; 7 species were legumes, nuts, and seeds; and 8 species were used as spices, condiments, and beverages. Using the statistical software R with ethnobotanyR package, we further calculated the ethnobotanical indices (use-report (UR), use-value (UV), number of use (NU), and fidelity level (FL)) from 1254 URs in all 9 food use-categories. The species with the highest UV and UR were from a variety of nutrient-rich edible plants such as Ipomoea batatas (L.) Lam., Musa species, Colocasia esculenta (L.) Schott, Zea mays L., and Manihot esculenta Crantz. The extensive utilization of root and tuber crops along with corn and plantain that contain a higher amount of energy and protein, carbohydrates, minerals, and vitamins were shown to be an important nutrient-rich alternatives to rice. Whilst males appeared to be more knowledgeable of edible plant species collected from the forests and communal areas, there were no significant differences between males and females in terms of knowledge of edible plants collected from homegardens, riverbanks, and farms. The various food collection sites of the Higaonon tribe may be considered as food biocultural refugia given their socio-ecological function in food security, biodiversity conservation, and preservation of indigenous knowledge.

Sustainable agriculture plays an important role in achieving sustainable development goals with regard to food security and environmental conservation. Sustainable agriculture relies on sustainable farming practices that reduce greenhouse gas production, the wise use of local natural resources, and reductions in negative impacts on the environment and human health. Sustainable farming practices can be driven by various factors, such as the socio-environmental setting, socio-cognitive factors, agricultural institutions, and policy. This study used the knowledge, attitude, and practice (KAP) model to examine farmers’ knowledge, attitudes, and practices in the area of sustainable agriculture. It also considered the factors affecting farmers’ knowledge, attitudes, and practices. Two different socio-environmental contextual settings in Surin Province (a Thai-Cambodian border province) of Thailand are considered. The results show that there are differences between the two different socio-environmental contextual settings with regard to farmers’ sustainable agricultural practice perceptions, knowledge, and attitudes. Farmers’ perceptions of environmental degradation, the number of years of agricultural experience, and agricultural policy drive farmers’ attitudes and individual sustainable practices. Another major result of the study is that individual farmers’ attitudes and practices promote collective sustainable agricultural behaviors. The implication of these findings is that it is necessary to improve the learning ability of individual farmers on the environment and sustainable agricultural practices through social learning and scientific knowledge dissemination, so as to produce sustainable collective development behaviors.

The relationship between a university and its city is considered strategical to achieve university targeted ambitions and visions. The university-city relationship is also encouraged for the benefit of the city, as universities unleash their respective cities’ potentials to act as driving forces not only for their local communities, but also for the whole nation. Therefore, maintaining a mutual relationship between the university and the city is considered essential to accomplish strategic goals for both. However, the nature of this relationship is quite complex, overlapped, interconnected, and diverse. Therefore, this paper conducted a systematic review of the literature on university-city and campus-city relationships to evaluate recent research trends to uncover the aspects that connect universities with their respective cities. The search included articles published in 4 different databases from January 1990 to January 2021. A total number of 50 articles were selected in this review. The findings uncovered different aspects that could help or hinder university-city relationship based on the physical and functional linkage between the campus and the city. Moreover, findings have shown that it is necessary to understand universities according to their contextual differences, as universities have shown different impacts on their respective cities in terms of their sizes and locations. Results have also shown that the impact of the physical connection between the university and the city goes far beyond campus’s accessibility as it deeply affects students’ social life as well. Therefore, decision makers, stakeholders, and university administrators need to co-design campus development process especially in the early stages to maximize the mutual benefits of campus-city relationship. The main conclusions of this paper address several perspectives and lessons for a more sustainable campus-city relationship.

The relationship between stakeholders and the environment influences sustainable development and human wellbeing. To illustrate the multi-stakeholder perceptions of environmental pollution in China, we interpreted a feedback loop in the perception-behavior-environment nexus from the perspective of the coupled human-environment system, measured the differences of environmental perceptions among five stakeholders (the public, government, media, companies, and scientists) and regions (including 31 provinces, autonomous regions, and municipalities in China, with exceptions of Taiwan of China, Hong Kong of China, and Macao of China due to a lack of data) using big data, and made a comparison between the perceptions and the actual pollution situation. The results showed that the five stakeholders exhibited similar perceptions of environmental pollution at the national scale, with air pollution being of most concern, followed by water pollution and soil pollution. There were significant spatial differences in environmental perceptions. All stakeholders in the developed regions in eastern China paid relatively high attention to environmental issues, while those in the northwestern regions paid much less attention. There existed a mutual influence and interaction among the different stakeholders. More attention should be paid to air pollution in Xinjiang Uygur Autonomous Region and Ningxia Hui Autonomous Region, water pollution in Hainan Province, Inner Mongolia Autonomous Region, Heilongjiang Province, and Jilin Province, and soil pollution in Hainan Province, Fujian Province, and Jilin Province. This paper provides a research paradigm on multi-stakeholder environmental perceptions based on big data, and the results provide a background reference for regional environmental governance.

Traditional rural homegarden agroforestry system in the Chengdu Plain of China, called “Linpan” in Chinese, integrates the ecological functions of the landscape with human production activities. Studying the driving mechanisms of rural landscape changes in the Chengdu Plain is of great significance from stakeholders’ perspective. Taking the Pidu Linpan Farming System (PLFS) in the suburban area of Chengdu (designated as one of China-Nationally Important Agricultural Heritage Systems in 2020) as a case, this study combined remote sensing image analysis, oral history interviews, and focus group interviews to elucidate the driving forces of landscape changes in the PLFS. The results show that tourism development, traffic accessibility, economic demand, and agricultural heritage protection measure are the main driving forces promoting the stability and maintenance of the traditional homegardens. In contrast, population ageing, land circulation, centralized residence, climate change, and living and recreational need are the forces leading to adverse changes in the traditional homegardens. In addition, these driving forces have led to the gradual abandonment of traditional agricultural activities and critical issues related to rural landscape planning and management. The current research indicates that infrastructure construction and increased traditional agricultural income are considered as the best practices of local stakeholders, promoting the development of the protected homegardens of heritage sites and tourist destinations. Finally, we put forward some suggestions to improve and maintain the traditional rural landscape: (1) establishing a benefit-sharing mechanism; (2) establishing a training system with traditional technology and culture; (3) strengthening infrastructure construction; (4) promoting the development of the agricultural industry; (5) improving the cultural quality of farmers; and (6) establishing a management system with legal effects. This research can provide a basis for the formulation of rural landscape planning and the orderly and healthy development of agricultural heritage in Chengdu Plain.

Studies on carbon emissions associated with land use and cover change (LUCC) are key to understanding the impact of human activities on regional sustainability. In this study, we analyzed the temporal and spatial changes in carbon emissions associated with LUCC for production, living, and ecological spaces in Zhengzhou City of China. Landsat remote sensing images were used to classify the land use and land cover (LULC) types in Zhengzhou City in 1988, 2001, 2009, and 2015. Carbon emissions associated with LUCC were evaluated using a spatial gradient model and the niche mechanism. It was found that during 1988–2015, carbon emissions associated with LUCC in Zhengzhou City increased by 17.1 ​× ​10⁶ ​t, while the carbon sink resulted from cultivated land, forests, water bodies, and unused land decreased significantly. Most of the increase in carbon emissions associated with LUCC occurred in the center of the city. The peak carbon emissions were located in the northeastern, southeastern, northwestern, and southwestern regions of Zhengzhou City, and carbon emissions varied considerably in the different spatial gradient rings over time. Among the three spaces, carbon emissions associated with LUCC were mainly affected by the living space. The population size and population urbanization rate were negatively correlated with the ecological space and positively correlated with the production and living spaces. Our results highlight that Zhengzhou City should take the new urbanization path of urban transformation development and ecological civilization construction to ensure the realization of the promised carbon emission reduction targets.

Ecotourism projects are mostly implemented in naturally fragile ecosystems as a savior of nature, culture, and indigenous people. This paper aims to make quantitative study of ecotourism in protected areas by using bibliometric analysis. VOSviewer, a popular bibliometric software, was used to analyze as many as 1182 research articles published from 2002 to 2020. Those articles were collected from the Scopus database. The study measured three distinct types of bibliometric indicators (quantity, quality, and structural indicators) to analyze the published articles scientifically. The analysis uncovers ecotourism research in protected areas as an emerging and predominant field of research with a sound growth in annual publications and citations. Importantly, the majority of ecotourism research articles are published in the United States, the United Kingdom, Australia, South Africa, Canada, and China. Nevertheless, ecotourism as a relevant research theme of is getting due importance in African and Asian countries for two key reasons: (1) wildlife and tribal populations, and (2) uncontaminated ecology and environment of ecotourism sites. Further, the main research themes of articles in the field of ecotourism in protected areas are broadly focused on conservation, visitor management, and community. Our findings reveal that controversial issues surrounding ecotourism and its relationship to protected areas, dominated by human-wildlife conflict, gender, and climate change, are attracting the attention of researchers worldwide.

The production and trade of primary products had a growing impact on the economic security of all countries and regions, and the strategic position of these products in the global trade network was becoming increasingly prominent. Based on complex network theory, this paper explored the spatial pattern and complex structural evolution of the global primary product trade network (GPPTN) during 1985–2015 by using index methods, such as centrality, Sankey diagram, and structure entropy, focusing on the diversified spatial structure of China’s import and export markets for primary products (with exceptions of Taiwan of China, Hong Kong of China, and Macao of China due to a lack of data) and their geographical implications for China’s energy security. The research offered the following key findings. The GPPTN showed an obvious spatial heterogeneity pattern, and the area of import consumption was more concentrated; however, the overall trend was decentralized. The trade center of gravity shifted eastwards and reflected the rise of emerging markets. The overall flow of the GPPTN was from west to east and from south to north. In terms of the community detection of the GPPTN, North America, Europe, and Asia increasingly presented an unbalanced “tripartite confrontation”. China’s exports of primary products were mainly concentrated in the Association of Southeast Asian Nations (ASEAN) and other peripheral regions of Asia, and its imports undergone a major transformation, gradually expanding from the peripheral regions of Asia to Africa, the Middle East, Latin America, and other parts of the world. Energy fuels also became the largest imported primary products. Based on the changing trend of structural entropy and main market share, the analysis showed that the stable supply of China’s energy diversification was gradually realized. In particular, the cooperation dividend proposed by the Belt and Road initiative became an important turning point and a strong support for the expansion of China’s energy market diversification pattern and guarantee of energy security.

Forests are considered as a sacred asset in India and have guided the way of living throughout its history. Indian forests not only accommodate the myriad species but also act as a survival support system to the communities that depended on them. The 2030 Agenda for Sustainable Development proposed by the United Nations (UN) has gained momentum and becomes an integral part of the recent efforts of Indian governance. In this investigation, we examined the potential nexus between Indian forestry system (biodiversity-enriched assets, ecosystem services, constitutional mechanisms, and governances) and Sustainable Development Goals (SDGs) through theoretical underpinnings from literature that selected from database like Google Scholar, Indian forest survey reports, and information retrieved from Indian government websites. The significance of this review is that it presents comprehensive information about Indian forestry, biodiversity-rich assets, and sustainable forest management practices. The results show that Indian forestry as a whole is an integral part of the food-energy-water cycle and contributes to all dimensions of sustainable development, i.e., economic sustainability, social sustainability, and environmental sustainability. The investigation confirms that besides partly contributing to the economy and life support systems to many dependent species, forests also act as boosters in the areas of food security and health. Targets related to the climate action, peace, and partnership goals are well in place through various forestry interventions and environmental commitments by the Government of India.

This paper examined the prioritized climate-smart agricultural practices by smallholder farmers, the motivations of adopting climate-smart agricultural practices, the enablers to the successful adoption of climate-smart agricultural practices, and the barriers to the successful adoption of climate-smart agricultural practices in the transitional and savannah agroecological zones of Ghana. Specifically, we employed ethnographic research using participatory approaches, including two stakeholder workshops and household surveys with 1061 households in the transitional and savannah agroecological zones of Ghana. The weighted average index (WAI) and problem confrontation index (PCI) were used to rank smallholder farmers’ perceived enablers to the adoption of climate-smart agricultural practices and the barriers affecting climate-smart agricultural practices, respectively. Results suggest that the majority of the respondents used a suite of climate-smart agricultural practices, including the timely harvesting of produce and storage, emergency seed banking, appropriate and timely weed and pest control, and early planting as practices to build climate resilience. The majority of smallholder farmers primarily employed climate-smart agricultural practices to improve household food security (96.2%), reduce pests and diseases (95.6%), and obtain higher yields and greater farm income (93.2%). Findings also show that secured land tenure system arrangement, understanding the effects of climate change, and access to sustainable agricultural technologies were ranked the first, second, and third most important enablers to the adoption of climate-smart agricultural practices with the WAI values of 2.86, 2.75, and 2.70, respectively. Key barriers to the successful adoption of climate-smart agricultural practices included incidences of pests and diseases (PCI = 2530), inadequate access to agricultural credit (PCI = 2502), high cost of improved crop varieties (PCI = 2334), and limited government support with farm inputs (PCI = 2296). Smallholder farmers need to be better supported through the provision of appropriate institutional and policy arrangements together with improved land management extension advice to overcome these barriers and facilitate the more effective implementation of climate-smart agricultural practices in Ghana.
