Background: Despite increasing attention and a growing volume of research data, little physiological evidence is available on the benefits of horticultural activity and the different effects on individuals. Therefore, the aim of the present study was to investigate the physiological effects of horticultural activity and to examine how differences in personality alter these effects. Results: The effects of transplanting real flowers (horticultural activity) and handling artificial flowers (control activity) on human physiological activity were compared. On the first day, eight participants engaged in horticultural activity and another eight in the control activity. On the second day, participants switched roles. Participants' physiological conditions during each activity were assessed by measuring the heart rate and heart rate variability (HRV). Psychological responses, which were measured using a semantic differential rating scale, showed that the horticultural activity promoted comfortable, soothed, and natural feelings, compared to the control activity. Analysis of physiological responses using two-way repeated measures analysis of variance (ANOVA) revealed that sympathetic nervous activity significantly decreased in the late time period (11 to 15 minutes) of horticultural activity only in the type A group. Conclusions: This study supports the fact that the horticultural activity can enhance psychological and physiological relaxation effects, although these physiological effects can differ among individuals with different personalities. © 2013 Lee et al.; licensee BioMed Central Ltd.

The present study investigated the well-being effects of short-term forest walking and viewing ("forest bathing"). The hypothesis in our study was that both environment (forest vs. urban) and activity (walking and viewing) would influence psychological outcomes. An additional aim was to enhance basic research using several psychological methods. We conducted the experiments using 45 respondents in four areas of Japan from August to September, 2011. The hypothesis in our study was supported, because significant interaction terms between the environment and activity were confirmed regarding the Profile of Mood States (POMS) indexes, Restorative Outcome Scale (ROS) and Subjective Vitality Scale (SVS). No statistical differences between the two experimental groups in any of the ten scales were found before the experiment. However, feelings of vigor and positive effects, as well as feelings of subjective recovery and vitality were stronger in the forest environment than in the urban environment. © 2014 by the authors; licensee MDPI, Basel, Switzerland.

In the Philippines, indigenous knowledge has been recognized to contribute to sustainability of production systems, having been validated for their technical and scientific soundness by many investigators. It was in 1992 that the Philippine government gave recognition to the potentials of indigenous knowledge systems following the Earth Summit in 1992. Prior to this, scientists/researchers, development workers and lawmakers in the Philippines were preoccupied with their craft seeking "modern" ways of doing and accomplishing things. Cordillera in the Northern Philippines is a host to many indigenous cultures like Isneg, Kalinga, Bontok, Kankanaey, Tingguian, Gaddang, Ayangan and Tuwali, Kalanguya or Ikalahan, Ibaloy and Karao whose traditional knowledge systems were subject of many studies and investigations.The paper describes the different knowledge systems for natural resources management in the Cordillera as practiced by the people with different beliefs, culture and traditions. The paper showcases different resource conserving experiences in these cultures like muyong and ala-a systems of the Ifugaos; lapat among the Isneg and Tingguians; inum-an, gen-gen, day-og, balkah, kinebbah, tuping and pamettey of the Ikalahans. These knowledge systems have been practiced by the indigenous peoples in the Cordillera and have been transmitted from generation to generation, making their way of life in harmony with their physical and social surroundings. While culture is environment specific, adoption/transfer of some indigenous technologies that may be fitting to other cultures and communities, with a little modification to suit their needs, can be done. © 2010.

The present study investigated the physiological and psychological effects of viewing urban forest landscapes on 48 young male urban residents. Four forested areas and four urban areas located in central and western Japan were used as the test sites. We found that in the forested areas, the subjects exhibited (i) significantly lower diastolic blood pressure, (ii) significantly higher parasympathetic nervous activity, but significantly lower sympathetic nervous activity, and (iii) significantly lower heart rate. The forest landscapes (iv) obtained better scores in subjective ratings, and (v) induced significantly less negative and more vigorous moods. Taken as whole, these findings suggest that even a short-term viewing of forests has relaxing effects. We have thus concluded that the approach taken in this study is useful in exploring the influences of urban green space on humans, as well as contributing to the planning and design of a healthy environment for urban residents. © 2013 Elsevier B.V.

Empirical evidence suggests that three-dimensional (3D) images of nature promote physiological relaxation in humans by providing more realistic effects compared with two-dimensional (2D) images. However, no studies have evaluated the physiological relaxation effects of nature-derived 3D images on prefrontal cortex and autonomic nerve activity. The present study aimed to clarify the physiological relaxation effects of visual stimulation by 3D flower images on prefrontal cortex and autonomic nerve activity. Nineteen male university students (22.2 ± 0.6 years) were presented with 3D and 2D images of the water lily for 90 s. Prefrontal cortex activity was measured using near-infrared spectroscopy, while autonomic nerve activity was measured using heart rate variability (HRV). Psychological effects were determined using a modified semantic differential method (SD). Compared with visual stimulation by 2D images, that by 3D images resulted in a significant decrease in oxyhemoglobin concentration in the right prefrontal cortex, lower sympathetic activity as calculated by the ratio of the low-frequency to high-frequency HRV component, and a significantly greater realistic feeling as evidenced by higher SD ratings. In conclusion, visual stimulation by realistic 3D floral images promotes physiological relaxation more effectively than the corresponding 2D image. © 2014, Marta Olivetti Belardinelli and Springer-Verlag Berlin Heidelberg.
