“…A arborização urbana é um elemento com inúmeros impactos positivos para a qualidade ambiental: proporciona proteção solar para os edifícios, reduzindo o consumo de energia para o condicionamento térmico interno devido ao seu efeito de sombra [1]; redução da radiação UV abaixo da copa e nas proximidades [2] [3] [4] [5]; redução do processo de erosão, atuando no controle da velocidade do vento, na mitigação da poluição do ar [6] [7]; habitat para algumas espécies de vida selvagem [8]; aumento dos laços de vizinhança, despertando o senso de comunidade [9]; benefícios que atuam diretamente na melhora da saúde mental e física das pessoas [10].…”

Árvores se constituem em elementos complexos quando observadas em relação à transmissão, reflexão e dispersão da luz. Variáveis como altura, geometria e forma da copa, das folhas, do tronco e galhos, bem como, cor e transparência impactam na trajetória da luz. Assim, esse artigo apresenta resultados de uma investigação conduzida com o objetivo de mensurar e analisar o impacto da vegetação na iluminação natural de ambientes internos. O método proposto consiste em utilizar uma espécie arbórea em escala reduzida (bonsai), simulando uma vegetação em tamanho real, em conjunto com ambientes internos, em escala reduzida, e medições da iluminância interna sob céu real. Os resultados obtidos demonstram que a obstrução causada pela árvore pode reduzir expressivamente (68%) as iluminâncias internas, por outro lado, a vegetação contribuiu para a uniformidade nos níveis da iluminação.

“…These forested areas are known as urban forests. Urban forest benefits range from ecological well-being to socioeconomic contributions, making it an important part of sustainable urban development [1]. Among the many ecosystem services of urban forests is the recovery function on human health [2].…”

Sustainable urban development is a major issue in developing countries, namely in environmental and social aspects. Urban forests have the potential to address these issues. Thus, it is not surprising that urban forest research is slowly gaining traction in these regions. However, there have been limited urban forest research reviews focusing on developing countries, especially tropical countries in the global south. Research reviews are vital in identifying the distribution of research themes, hence revealing research gaps and needs. Therefore, this review paper aims to provide a deep insight into the development of urban forest research in Malaysia in the past 20 years. The core purpose of this review is to analyze the distribution of research themes in Malaysia, thus identifying research gaps and needs in developing countries. A total of 43 articles were selected for this review, using the PRISMA framework. The distribution of research articles showed a continuous increase over time, especially for the past five years (2016 to 2021). The reviewed articles were categorized according to five emerging research themes in urban forestry. More than 41% of the reviewed articles fell under Theme 1 (the physicality of urban forests), with the majority being on biodiversity (n = 10). Theme 5 (the governance of urban forest) had the lowest research output (n = 3). Urban forestry research is slowly gaining prominence globally including the global south; however, there are obvious preferences in research focus, causing some research questions to be neglected. These research gaps are especially evident in four areas—soil science, ecophysiology, valuation (economics), and environmental justice. These research gaps should be addressed by the scientific community to ensure a thorough and complete research growth pertaining to urban forestry.

“…• Technical information and guidance on built and natural shade design and development [2,7,8,17,37,44,57]; • A summary of relevant built environment metrics which was intended to guide future efforts in developing shade targets (see Table 4 in the Benchmarking Share in NSW full report [2]); • Existing metrics which playground shade metrics could be integrated into e.g., a trialled Liveable Neighbourhood guideline that currently includes street shade [25], and • Playground heat mitigation metrics [9,43,44].…”

Strategies to increase shade in public playgrounds: A realist review

Australia has one of the highest skin cancer incidences globally. Quality shade, which is a well-designed and correctly positioned combination of natural and built shade, can reduce solar ultraviolet radiation exposure by up to 75%. Existing shade in playgrounds in NSW was benchmarked in 2020-2021; this demonstrated a clear need for improvements to be made. This realist review sought to find evidence of shade targets and other complex strategies to increase shade in playgrounds. Fifty-nine documents (31 peer reviewed and 28 grey literature) contributed data to address the evidence review questions. Twenty-five examples of strategies, with a description of their implementation and/or reporting of outcomes, used to increase shade in playgrounds were located. Six types of strategies were identified: policies, guidelines and recommendations; settings-based site audits and site plans; city-level tree and shade site masterplan; monetary incentives; targets and other metrics; and multi-component interventions. For the strategies themselves, the review found evidence of intermediate changes such as the adoption of the strategy, but a lack of evidence of strategies leading to increased shade in playgrounds. Five enablers, five barriers and one barrier/enabler to the implementation of strategies to increase shade in playground were found in the literature. Expert opinion from reviews suggests that shade provision for skin cancer prevention is best affected through integration with other policies.
