    Can Strategic Environmental Assessment (SEA) contribute towards the implementation of biophilic urbanism in urban planning? The case of Chilean Municipal Regulatory Plans
    (Elsevier Inc., 2022) Carter V.; Henriquez C.; Henriquez C.; CEDEUS (Chile)
    © 2022 Elsevier Inc.The COVID-19 crisis has again highlighted our need to be in close contact with nature. Approaches such as biophilic urbanism, which seek to re-naturalize cities through its inclusion in planning and design, have thus gained relevance. The biophilic urbanism approach is materialized through the Biophilic Cities Network (BCN) and uses indicators to measure cities' biophilic performance. To date, Chilean cities have not formally implemented the approach. However, the Strategic Environmental Assessment (SEA), a mandatory policy process, requires the inclusion of environmental issues in Chilean urban planning. The purpose of this paper is to explore the extent to which SEA might contribute towards the implementation of biophilic urbanism in planning processes. We analyze how local governments have been including biophilic elements in their SEA processes by exploring the Communal Regulatory Plan (PRC). We perform a content analysis on the indicators in 135 reports associated with each SEA process. The analysis revealed 286 of 1,006 indicators containing biophilic elements extracted from the biophilic cities indicators. We found that biophilic elements linked with the inhabitant's engagement and well-being were largely absent. Conversely, those indicators related to the creation of new green urban infrastructures were widely represented. Overall, the paper hints at the potential usefulness of the SEA to increase biophilic urbanism implementation in urban planning by applying indicators that include biophilic elements.

All rights reserved.Urban wetlands are supplied by the rainwater system and store large amounts of water for their vegetation and hydromorphic soils, while contributing to the regulation of flows in cities, however, they have been affected by urbanization processes. As is the case of the Bogotá wetlands, which are invaded by illegal settlements affecting environmental preservation areas, so studies are required to analyze: urban growth, and the trend of rainfall. The urbanization analysis techniques are calculated from the Normalized Built Difference Index (NDBI), which integrates the combination of satellite images for its de-termination. The rainwater trend is analyzed from the IDF curves (intensity-duration-fre-quency). The results show that the wetlands are invaded on average by 7.5% in the city. With regard to the intensity of rainwater, it is mainly concentrated in the eastern hills of Bogotá and due to the effects of runoff, the flow of water runs from east to west, reaching the main wetlands and lakes. Then the information is validated with the calculation of the Normalized Difference Water Index (NDWI), which shows high concentrations of humidity in the western part of the city.
