Contributions of urban green infrastructure in Poligono Central, Santo Domingo, Dominican Republic

Description

This research seeks to answer the following questions: What are the contributions of green infrastructure in the reduction of the urban heat island in the Central Polygon of the National District? What are the strategies for adaptation to climate change, including contributions to the regulations of green infrastructure for urban trees in the Central Industrial Estate of the National District? What is the economic value of the ecosystem services of urban trees for the families of the Polígono Central? The urban heat island (UHI) and greenhouse gas emissions (GHG) are phenomena that affect the temperature and quality of life of city residents. Studies show that urban trees can be used as a tool to mitigate these phenomena. The research proposes methodological strategies that evaluate urban trees, determine adaptation measures to climate change through green infrastructure, evaluate strategies for the regulation of urban trees in the National District and its assessment. In addition, consultations with experts, training of professionals (RAUDO, ADRU AND RIADRU) and scientific publications in indexed journals will be carried out. The results provide elements for the establishment of public policies that contribute to the National Development Strategy, the National Climate Change Policy and the Sustainable Development Goals (SDG). Keywords: urban heat island, adaptation to climate change, green infrastructure, thermal comfort, radiant temperature, economic value of urban trees.

Steps to reproduce

In the development of the research questions, which are grouped into four points: -Contributions of urban trees: What type of urban trees is most suitable as a tool for mitigating thermal contributions to the environment? What percentage of temperature reduction in the environment is achieved through urban trees? Is there a database of tree biodiversity and microclimate of the central polygon? -Climate change adaptation strategies: What costs and consequences of climate change are already being perceived? What strategies are the most suitable for adaptation to climate change? What strategy does the regulations have to deal with these phenomena? What contributions can be made to urban tree regulations? -Economic value of the ecosystem services of urban trees: What is the impact of the ecosystem services of urban trees for families in the central area of ​​Santo Domingo? How does the loss of environmental quality affect the health and quality of life of the families in the central area of ​​the city of Santo Domingo? What are the ecosystem services of urban forests best valued by citizens in the city of Santo Domingo? The methodological strategies to implement are the following: -Collection and evaluation of urban data -Climatic evaluation of the Central Polygon -Preparation of measurement sheets and surveys -Urban survey of the study area -Carrying out field measurements -Calculation of thermal comfort indices at urban level -Economic valuation of the ecosystem services of urban trees and the impacts of the urban heat index on families in the central industrial area of ​​Santo Domingo. Strategies one and two allow obtaining a database on the current state of the referring Central Polygon. The third strategy allows creating a data collection tool at the survey level as well as at the user perception level. The fourth strategy allows recognizing the study area at a specific level at the level of trees and public space. The fifth strategy allows the collection of data from study indicators for evaluation. The sixth strategy constitutes the tool that allows us to approach the state of comfort of users in public spaces. In the case of economic valuation, it provides relevant information for public policies, GHG inventories, economic analysis of adaptation to climate change and effective public health strategies. For the economic valuation, a contingent valuation will be carried out, which is a direct valuation technique that belongs to the family of methods based on the analysis of declared preferences, such as the selection experiment and conjoint analysis, based on the approximation of the value of goods and services without ordinary market prices, such as air quality, the conservation of natural resources, among other environmental attributes from the creation of hypothetical markets (Akhtar, Saleem, Nadeem, Shahid, & Ikram, 2017; Richard T. Carson , 2012; Hanemann, 1994).
