SARVA 3.0

The South African Risk and Vulnerability Atlas is an open access platform that unites data to solve complex interconnected problems. SARVA is a living collection of global change resources – including scientific data and long-term observations, static content, references to documentation and reports, and other digital objects.

SARVA is an initiative of the Department of Science and Innovation and forms a 10-year Global Change Grand Challenge. It is currently in its third phase of implementation.

Hazard Data Sources
SDG 13 & 15

 The dataset is a collection of databases and sources, curated to provide essential information about natural hazards within the South African context.

Daily air quality estimates for urban centers in Africa
SDG 11: Indicator 11.6.2

This dataset contains daily estimates of PM2.5 particulate matter in 1466 cities across Africa as well as an additional 496 smaller population clusters in South Africa.

South African hazardous events mortalities data
SDG 1: Indicator 1.5.1D

Supporting data for – Davis-Reddy, Claire & Hilgart, Amelia. (2021). Towards an interoperable National Hazards Events Database for South Africa. Frontiers in Climate. 

Terrestrial Environment Data
SDG 15

A curation of a collection of publications, reports, spatial datasets and spreadsheets of terrestrial datasets. The collection contains 252 open datasets published in the SAEON catalogue.

Gauteng City-Region Observatory (GCRO) Quality of Life Data
SDG 1-17

These dataset are from the Gauteng City-Region Observatory which is a partnership between the University of Johannesburg, the University of the Witwatersrand, the Gauteng Provincial Government and several Gauteng municipalities. The GCRO has conducted previous Quality of Life Surveys in 2009 (Round 1), 2011 (Round 2), 2013-2014 (Round 3) and 2015-2016 (Round 4), and 2017-2018 (Round 5). Round 6 was conducted in 2020-2021 and is the latest round of the survey.

Risk and Vulnerability

The world is facing a number of complex global challenges or risks. These include changes in the climate system as well as changes in biophysical and human systems such as urbanisation, deforestation, biodiversity loss and, more recently, the rise of pandemics.

Tracking risks and identifying the susceptibility of communities, settlements, or ecosystems to these risks will assist in building more sustainable economies and societies that are more resilient. 

Risks

SARVA 3.0 presents the spatial and temporal characteristics of a growing number of risks facing South Africa in order to enable decision-makers to identify vulnerable regions, ecosystems and communities.

Vulnerability

SARVA 3.0 provides access to datasets and interactive visualisations of 53 vulnerability indicators that can be used to measure the ability of environmental, economic, and social systems to cope with global change.

Sustainability

The district-level Sustainable Development Goal indicator tool links higher spatial and temporal resolution data from a variety of sources to each of the 17 SDGs and associated targets and indicators. We currently have data that covers 15 out of the 17 goals. Click on the SDG logos to view each of the data collections
