Nature and health researchers have often suggested that nature induces better psychological and physical health responses than urban environments, especially with healthy ecosystems in nature. However, research that has empirically documented the daily benefits of physical and psychological health in rural landscapes is scarce. This study explores how rural landscapes could provide better health benefits than the built environment in daily life. The research involved on-site data collection with a set of psychological indicators (e.g., restorativeness, preference, emotion) and physical indicators (e.g., brain waves, heart rate) to compare the rural and the built environments. A total of 169 subjects took part in the study. We analyzed health indicators through analysis of variance to show the difference in water landscapes in rural areas relative to the built environment after the participants experienced the environments. The results showed that subjects could release stress and felt a greater sense of restorativeness, pleasure, and arousal in rural areas than in the built environment. Subjects preferred the rural landscape more than the built environment. To conclude, this study explains the rural landscape and its health-related benefits in Taiwan.
Research has confirmed that there are physical and mental benefits associated with performing horticultural activities, such as being in contact with soil and viewing plants. In addition, due to the rapidly increasing volume of affective neuroscience research, it is now possible to understand emotional processing in the brain through neuroimaging. The present study was conducted to explore subjects’ emotional responses after participating in horticultural activities, with functional magnetic resonance imaging (fMRI) and the Profile of Mood States used for physiological and psychological measurements, respectively. First, the subjects’ baseline brain activation levels were determined before any engagement in horticultural activities. A week later, the subjects participated in a 5-week horticultural activity. fMRI was used to detect physiological changes during the different stages of the activity—namely, preparation and sowing, fertilizing and weeding, and harvesting. The findings show that the functional connectivity of the brain regions was activated, including the emotional prosody network. Hence, this study provides evidence that gardening can stimulate functional connectivity, activation of positive emotions, and mindfulness in the brain. The findings provide a neuroscientific understanding of the types of horticultural activities that increase positive emotions, meditation, creativity, attention, and relaxation and reduce depression.
Chile pepper (Capsicum annuum) is an increasingly important crop worldwide, and Vietnam and Myanmar are major producing countries. The chile pepper markets in Myanmar and Vietnam are different, with production primarily for domestic consumption in Myanmar and for the export market in Vietnam. However, there is an overall lack of domestically developed cultivars in both countries. The objective of this study was to identify high-performing chile pepper entries, adapted to local conditions, for use in domestic breeding programs or direct release. Fruit length, width, weight, and yield were measured during two seasons (2016–17 and 2018–19), and the same entries were evaluated in Hanoi, Vietnam, and Nay Pyi Taw, Myanmar. However, different entries were tested in each season. During the 2016–17 season, AVPP1324 grown in Hanoi had the overall highest yield (15.3 t·ha–1), followed by AVPP1330 (15.0 t·ha–1 in Hanoi) and AVPP1111 (14.4 and 14.9 t·ha–1 in Hanoi and Nay Pyi Taw, respectively). AVPP0303 had the greatest fruit length, fruit width, and fruit weight in both Hanoi and Nay Pyi Taw during the 2016–17 season. During the 2018–19 season, AVPP1345 (24.8 t·ha–1) followed by AVPP9905 (22.5 t·ha–1) in Nay Pyi Taw, and AVPP1245 (17.4 t·ha–1) in Hanoi had the highest yield. AVPP9905 had the greatest fruit weight and width in both locations. AVPP1345 and AVPP9905 had the greatest fruit length during the 2018–19 season. There is an obvious need for domestically produced cultivars in Myanmar and Vietnam that meet local farmer and consumer preferences and that are adapted to the pests, diseases, and stress in each country. Several high-performing lines were identified that can be used as direct release or incorporated in local breeding programs for the development of inbred or F1 hybrid cultivars. This research also provides a basis for future studies on stability of yield and yield components in Southeast Asia.
