This page describes the technical specifications of the Socio-hydrological resilience dataset for Mexico city and its Metropolitan Area. The data is presented as geometric polygon features representing administrative areas.

This research project was developed by the British Geological Survey, the Architectural Association, the Centre for Advanced Spatial Analysis and Fluxus. For more information about the project and methodology visit the project website.

The dataset comprises a set of variables that describe socio-hydrological vulnerability and the effects of building constructed wetlands for geographic areas called Colonias (n = 2785). Additionally, the effects of constructed wetlands are summarised at larger administrative areas called Alcaldias (n = ). The variables represent a description of the baseline (no constructed wetlands) for the actual 2020 and future 2050 situations and the estimation of the impacts of 4 budget schemes. Socio-hydrological vulnerability is represented by a Socio-hydrological index (SHI) which is the quotient between the Water Stress index (WSI) and the Adaptive Capacity index (ACI).

The impact of Constructed Wetlands (CW) in each Colonia is presented as the total amount of CW measured in square meters, and measured as total budget when this variable is aggregated to Alcaldias. Finally, the indexes and effects of CW (SHI, WSI, ACI and CW) are calculated for 3 world-views scenarios; Stakeholder, Environmental and Social. As illustrated in the data-cube figure below the combination of these parameters make up 120 variables for Colonias and 30 variables for Alcaldias (budget 0 variables for CW should be removed as this budget produces no impact making a final total of 114 and 24 variables)

The name of the variables is created from a string of the different parameters according to the following table. For example, the variable "ACI_c_w1_b1" corresponds to Adaptive Capacity index for 2020, Stakeholder weighting and budget 1

The values of all indices (SHI, WSI and ACI) are categorised and organised according to the following tables of value breaks, classes and colours

The interactive mock-up shows the map legends for SHI, WSI and ACI maps. This mock-up also shows the information included in Tooltips.

This interactive maps shows calculations of CW at Alcaldia level. The budget values come from the following formula

The breaks for the CW maps are created with the natural break or "jenks" algorithm. The table shows the breaks and corresponding colour from lower (1) t higher (10)

The 10 breaks in the previous table have the following values for ALCALDIAS (pesos) and COLONIAS (sqm) - (this requires testing to highlight Colonias that have an impact from CW across budgets, particularly for the smallest tiers)

The files containing the data are detailed below

The impacts of the CW is shown as a series of benefits variables (on a side summary panel). These can be calculated from the CW_sqm and CW_perc variables according to the following table.

This interactive map shows the benefit variables for each Colonia in the corresponding tooltip

Occasionally some variables show NA values. This occurs when it was not possible to compute the value due to missing data or when there is no constructed wetland built.
