The social and economic value of cultural ecosystem services provided by urban forests in North America: A review and suggestions for future research

With the majority of the world’s human population now living in cities, urban forests provide an increasingly important range of ecosystem services, from improved air quality and climate change adaptation to better public health outcomes and increased tourism revenues. The importance of these ecosystem services in urban environments, and the central role that cities play in the lives of people around the world, have motivated various attempts to quantify the value of ecosystem services provided by urban forests. This paper reviews existing research in the fields of urban forestry, economics, sociology, and health on the value of urban ecosystem services, with a focus on cultural services, a category of ecosystem services that is of key importance to human well-being but that has suffered from a lack of empirical research. The review identified 38 studies that examined the value of mixed vegetation, 31 studies that examined the value of trees, and 43 studies that examined the value of green spaces. Psychological health is the most-studied ecosystem service category, with most research in this area focusing on the services of mixed vegetation. Social health, community economic development, and tourism are the least-studied, with most research in these areas focusing on mixed vegetation and trees. Multiple metrics were used to quantify the value of urban greenery within each ecosystem service category but only 11 metrics were assigned a monetary value. Gaps in the literature that present strong opportunities for future research include: the value of urban forests for improving social health, equitable access to ecosystem services, the impact of urban forests on community economic development, and economic valuation and green exposure metrics. We hope that this review stimulates future research in the areas highlighted and that municipalities consider including evaluations of a broad range of ecosystem services during land use planning and budgeting processes.     

Improving fruit quality,nutritional value and yield of Zaghloul dates by the application of organic and/or mineral fertilizers

A field study was carried out during the years 2007 and 2008 on 30-year old Zaghloul cultivar growing in clay soil. Mineral fertilization sources: N, ammonium nitrate or NPK, ammonium nitrate + calcium superphosphate + potassium sulphate, and organic sources: chicken manure (CM), cow dung (CD) and composted domestic refuse (CDR) were applied either alone or in combinations in order to study their influence on the yield and fruit physical and chemical quality characteristics. The results revealed that applying organic manure alone or in combination with mineral NPK increased palm yield as compared to mineral fertilization alone (NPK or N). In general, fruit weight, flesh weight, length, diameter and dry weight were increased, while fruit moisture content decreased by the application of organic manures either alone or in combination with mineral NPK as compared to the mineral N. Higher fruit TSS and total sugars content were obtained by the application of organic manures alone or in combination with mineral NPK as compared with mineral fertilization alone (NPK or N). Overall values of fruit minerals content did not differ among the different treatments. Organic manures fertilization (especially CM and CD) resulted in decreasing fruit lead, cadmium, nitrate and nitrite contents more than mineral fertilization. In general, the application of organic manures either alone or in combinations with mineral NPK did not differ from each other in their effect on yield and fruit quality.

The lawn as a social and cultural phenomenon in Sweden

Lawns have a significant influence on the cityscape as one of the essential elements of green spaces and an important part of people’s everyday lives. Most people in the Western world view lawns as a compulsory element of the urban landscape, almost an icon, without questioning their social, symbolic, ecological or aesthetic values. This research is a part of the conceptual framework and methodological approaches that are being used in an ongoing transdisciplinary collaboration project to study lawns in Sweden as a social and ecological phenomenon.The overall aim of this study was to investigate social and cultural perceptions of lawns, as well as motives behind decisions about the establishment and management of lawns in Sweden. Two multi-family housing typologies, the ‘Million Programme’ and ‘People’s Homes’, were examined due to their dominance in Swedish cities. We also studied how an alternative vision of conventional lawns can be applied and accepted by urban residents. We estimated lawn cover in multi-family housing areas and links to people’s perception and use of lawns. Questionnaires, semi-structured interviews and observational studies were used (N = 300). Our results showed that people like lawns even if they do not always directly use them. Lawns cover the most significant amount of outdoor spaces in all multi-family residential areas and accompany people everywhere from the house to the schoolyard or park. The total lawn cover in the study areas was 27.8%. Lawns were particularly valued as important places for different outdoor activities (playing, resting, picnicking, walking, socialising) and enjoying the green colour. However people do not want to use a vast monotonous lawn, but a variety of spaces that provide good conditions for different senses (sound, smell, touch and sight) and activities. Alternative lawns were also appreciated by many citizens, politicians, planners and managers. The implementation of new types of lawns requires special planning and design solutions adjusted for each particular neighbourhood.     

The value of intrapericardial injection with a trans-diaphragmatic approach in the gene therapy of chronic heart failure rats

AIM: To study the feasibility, security and validity of the intrapericardial injection with a trans-diaphragmatic approach in chronic heart failure rats and its value in the study of gene therapy for heart diseases, and further investigate whether adeno-associated virual gene transfer of sarcoplasmic reticulum Ca2+-ATPase （SERCA2a） gene can improve ventricular function in chronic heart failure (HF) rats. METHODS: An animal model of heart failure was obtained by creating descending aortic constriction in rats. Recombinant adeno-associated virus, carrying enhanced green fluorescent protein (EGFP) gene and recombinant adeno-associated virus carrying SERCA2a gene, were respectively injected into pericardium of heart failure rats in different groups (group HF+EGFP and group HF+SERCA2a) by intrapericardial injection with a trans-diaphragmatic approach. After 30 days, hemodynamic parameters were measured and analyzed. Cryosection was analyzed by fluorescence microscopy to examine the expression of green fluorescent protein, and Western blotting was performed to detect the expression of SERCA2a. RESULTS: Green fluorescence was detected in cryosection of the hearts in all rats in group HF+EGFP and the expression of green fluorescent protein was ubiquitously. The expression of SERCA2a in all rats in group HF+SERCA2a was more than those in group HF and group HF+EGFP. And overexpression of SERCA2a improved the systolic and diastolic function of heart failure rats significantly and the hemodynamic parameters were similar with those of the controls. CONCLUSION: The intrapericardial injection with a trans-diaphragmatic approach suggests a simple, safe, efficient and cheap technique for the gene therapy of chronic heart failure. Gene thransfer of SERCA2a may be a new approach for the treatment of chronic heart failure.     

The effects of cultural factors on yield and curd quality of autumn cauliflower

The effects of six cultural treatments on (a) marketable yield, (b) percentage marketable plants and (c) percentage perfect quality curds produced, were studied on representative varieties of three groups of autumn cauliflower in experiments carried out over a period of five years. The treatments included a comparison of the use of graded and ungraded seed, transplanting and direct-drilling of the crop, different transplant ages, selection for uniformity at planting or thinning time, and plant density and nitrogen levels during the early seedling stage of growth.

In general the yields and quality of drilled and transplanted crops were similar with all varieties each year and neither the use of graded seed nor the nitrogen treatments had any significant effect on yield or curd quality. Both increasing plant density in the seedbed and increasing age of transplant caused a reduction in yield on most occasions. The effects of the treatments on yield and quality are discussed in relation to their effects on the maturity characteristics of the crops.
