Economic Value of Green Infrastructure and Quality of Life in Metropolitan Lima, Peru. Case: Districts Of Jesús Maria And Santiago De Surco.

Abstract

The objective of the study was to economically value (WTP) the urban green infrastructure of two districts of Metropolitan Lima, Peru, through the contingent valuation method to quantify the willingness of an individual to pay for its improvement and conservation, as well as to evidence the relationship between temperature, urban green infrastructure and human welfare by districts. A hypothetical market was created and 267 respondents, selected by random sampling, were asked to answer a pre-tested questionnaire. The results revealed that 95% of the respondents showed a positive willingness to pay and the mean predicted willingness to pay per person was $6.77 per month. A logistic regression model was used to develop the relationship between the independent variables and willingness to pay. Most of the parameters accompanied by the econometric analysis developed the expected results. The districts of Jesus Maria (HDI=0.84) and Santiago de Surco (HDI=0.80) have moderate to high NDVI and low to moderate temperatures, located in a desert area, natural desert environment, with little rainfall. The valuation should be complemented through the framework of the cultural ecosystem because they are broad, diverse and multiple.
