The relevance of urban agroforestry and urban remnant forest for avian diversity in a densely-populated developing country: The case of Port-au-Prince, Haiti
2021Jean-Marry Exantus, David Beaune, Frank Cézilly · Urban forestry & urban greening · Haiti (Port-au-Prince)
This study assessed bird assemblages in Port-au-Prince, Haiti, from January to April 2018, conducting 10 censuses per site across 16 urban green sites (8 forest patches, 8 agroforestry plantations) ranging from 1 to 11 ha. It recorded 32 bird species in forest patches and 34 in agroforestry sites, with an 85% overlap in species composition. Both species richness and diversity were negatively correlated with the percentage of built habitat within a 500-m radius around each site.
BiodiversityUrban–rural linkageHeavy metals and metalloids concentrations across UK urban horticultural soils and the factors influencing their bioavailability to food crops
2021Marta Crispo, Miriam C. Dobson, Roscoe S. Blevins, William Meredith, Janice A. Lake, Jill L. Edmondson · Environmental Pollution · United Kingdom
Heavy metal (HM) and metalloid concentrations were assessed in 200 urban horticultural soils across ten UK cities. HM were found to be widespread, with most concentrations below UK soil screening values (C4SLs). However, 83% of lead (Pb) concentrations exceeded C4SLs, which is a significant concern. Bioavailable HM concentrations represented a small fraction (0.01–1.8%) of total concentrations, and black carbon (BC) and organic carbon (OC) were suggested to contribute to HM immobilization.
Contamination & food safetyHealthCommunityBiodiversityComplementary analyses of soil microbial and chemical properties and human observation on augmented ecosystems in urban environment
2021Kousaku Ohta, Masatoshi Funabashi · Measurement Sensors · Global
This study achieved high biodiversity (over 200 plant species) on an urban rooftop garden using the Synecoculture method and analyzed soil microbial diversity, activity, and chemical properties over two years. Soil microbes gradually increased in diversity and activity after installation, showing a positive correlation with cation exchange capacity. After two years of continuous practice, human subjective evaluations were qualitatively consistent with objective data, suggesting that trained human subjectivity could be incorporated as part of assessment proxies in future ecosystem management research.
