However, existing mining methods for spatiotemporal association patterns usually model geographic phenomena as simple spatiotemporal point events. Therefore, they cannot be applied to complex geographic phenomena, which continuously change their properties, shapes or locations, such as storms and air pollution. The most salient feature of such complex geographic phenomena is the geographic dynamic. To fully reveal dynamic characteristics of complex geographic phenomena and discover their associated factors, this research proposes a novel complex event-based spatiotemporal association pattern mining framework. First, a complex geographic event was hierarchically modeled and represented by a new data structure named directed spatiotemporal routes. Then, sequence mining technique was applied to discover the spatiotemporal spread pattern of the complex geographic events. An adaptive spatiotemporal episode pattern mining algorithm was proposed to discover the candidate driving factors for the occurrence of complex geographic events. Finally, the proposed approach was evaluated by analyzing the air pollution in the region of Beijing-Tianjin-Hebei. The experimental results showed that the proposed approach can well address the geographic dynamic of complex geographic phenomena, such as the spatial spreading pattern and spatiotemporal interaction with candidate driving factors.

They can be divided into the following major categories: urban development, fragmentation, and isolation of forests; human pressures on soil and vegetation (e.g., changes in vegetation due to trampling, environmental and especially air pollution); human pressures on animals (e.g., wildlife losses due to collisions, frequent presence of dogs accompanying the visitors); and other threats and damages (e.g., littering and acts of vandalism). The directions of negative relations between people and forests shown in this review draw attention to the high complexity of the discussed issues. Awareness of this complexity (when planning and implementing forest management) can limit or counteract conflicts arising from the use of urban and suburban forests by people. This is of particular importance in the era of progressing urbanization and the evolution of human needs regarding the use of forests.

HackAIR : towards raising awareness about air quality in Europe by developing a collective online platform / Evangelos Kosmidis in ISPRS International journal of geo-information, vol 7 n° 5 (May 2018)

The current work aims to develop a centralized air quality data hub that enables citizens to contribute to air quality monitoring. In this work, data from official air quality monitoring stations are combined with air pollution estimates from sky-depicting photos and from low-cost sensing devices that citizens build on their own so that citizens receive improved information about the quality of the air they breathe. Additionally, a data fusion algorithm merges air quality information from various sources to provide information in areas where no air quality measurements exist.

Just good enough data and environmental sensing : moving beyond regulatory benchmarks toward citizen action / Jennifer Gabrys in International Journal of Spatial Data Infrastructures Research, vol 2018 n° 13 (Year 2018)  

Public [article]  inInternational Journal of Spatial Data Infrastructures Research > vol 2018 n° 13 (Year 2018) . - pp 4 - 14 Titre : Just good enough data and environmental sensing : moving beyond regulatory benchmarks toward citizen action Type de document : Article/Communication Auteurs : Jennifer Gabrys, Auteur ; Helen Pritchard, Auteur Année de publication : 2018 Article en page(s) : pp 4 - 14 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Sociologie [Termes descripteurs IGN] citoyen [Termes descripteurs IGN] données environnementales [Termes descripteurs IGN] pollution atmosphérique [Termes descripteurs IGN] science citoyenne [Termes descripteurs IGN] télédétection électromagnétique Résumé : (Auteur) Discussing a research project that investigates citizen sensing practices in relation to monitoring air pollution from hydraulic fracturing sites, this paper investigates the types of data that citizen monitoring generates, and the uses to which it might be put. The discussion is located within the wider context of the rise of environmental sensing technologies and practices that are emerging and that seek to enable citizens to use DIY and low-tech monitoring tools to understand and act upon environmental problems such as air pollution. These “citizen sensing” projects intend to gather data that can indicate environmental change and give rise to political action. However, regulators often contest citizen-gathered data as inaccurate, and as collected through sub-standard instruments and practices. Drawing on a report developed by the US EPA, we use the concept of “just good enough data” to demonstrate that citizen-gathered data can have multiple other uses beyond regulatory comparison and compliance. Describing the collaborative development of an environmental monitoring kit, as well as the deployment of this kit within a participatory research setting, we suggest that the relevance of citizen-collected air quality data should not be solely evaluated through absolute criteria such as alignment to state- or federally managed air quality data, but rather should be incorporated for the unique citizen-based insights and perspectives it provides.

Enhancing plant diversity and mitigating BVOC emissions of urban green spaces through the introduction of ornamental tree species / Yuan Ren in Urban Forestry & Urban Greening, vol 27 (October 2017)  

Public [article]  inUrban Forestry & Urban Greening > vol 27 (October 2017) . - pp 305 - 313 Titre : Enhancing plant diversity and mitigating BVOC emissions of urban green spaces through the introduction of ornamental tree species Type de document : Article/Communication Auteurs : Yuan Ren, Auteur ; Ying Ge, Auteur ; Danping Ma, Auteur ; et al., Auteur Année de publication : 2017 Article en page(s) : pp 305 - 313 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes descripteurs IGN] arbre urbain [Termes descripteurs IGN] biodiversité [Termes descripteurs IGN] espace vert [Termes descripteurs IGN] milieu urbain [Termes descripteurs IGN] ozone [Termes descripteurs IGN] pollution atmosphérique [Termes descripteurs IGN] service écosystémique [Termes descripteurs IGN] urbanisme [Termes descripteurs IGN] ville [Vedettes matières IGN] Economie forestière Résumé : (auteur) Promoting the plant diversity of urban green spaces is crucial to increase ecosystem services in urban areas. While introducing ornamental plants can enhance the biodiversity of green spaces it risks environmental impacts such as increasing emissions of biogenic volatile organic compounds (BVOCs) that are harmful to air quality and human health. The present study, taking Qingdao City as a case study, evaluated the plant diversity and BVOC emissions of urban green spaces and tried to find out a solution to increase biodiversity while reducing BVOC emissions. Results showed that: (1) the species diversity and phylogenetic diversity of trees in urban green spaces were 22% and 16% lower than rural forest of this region; (2) urban areas had higher BVOC emission intensity (2.6 g C m−2 yr−1) than their rural surroundings (2.1 g C m−2 yr−1); (3) introducing the selected 11 tree species will increase 15% and 11% of species diversity and phylogenetic diversity, respectively; and (4) the BVOC emissions from green spaces will more than triple by 2050, but a moderate introduction of the selected low-emitting trees species could reduce 34% of these emissions. The scheme of introducing low-emitting ornamental species leads to a win–win situation and also has implications for the sustainable green space management of other cities.
