title: Map of coastal Ecological Infrastructure demand, flow, capacity, and performance in South Africa

description: It is important to integrate ecosystem services into planning processes especially into systematic conservation planning. Using Ecological Infrastructure as a framework is one way to do so. This is the first version of a coastal Ecological Infrastructure map containing information on capacity, flow, demand, and performance of Ecological Infrastructure sites associated with the three ecosystem services nature-based sports events, nature-based recreational outdoor activities and coastal protection from flooding and erosion positioned in the seashore zone of the South African coast. The single sites of Ecological Infrastructure are delineated by the latest integrated map of coastal ecosystem types (2018) from the terrestrial, marine, and estuarine realms in South Africa. The capacity, flow, demand and performance indicators were built with simple additive models consisting of various direct and indirect variables based on causal relationships. The spatial information for the single variables was derived from various sources. A detailed description of the data sources and their use for the identification of Ecological Infrastructure sites and the assessment of capacity, demand, flow and performanc can be found in the methods section of Chapter 3 and Appendix 2 of the underlying PhD thesis “Interpretation, application and integration of Ecological Infrastructure in systematic conservation planning in the coastal zone”.

This digital version is in the public domain requiring only the conventional acknowledgement of source in publications and reports. APPROPRIATE USE OF THIS DATASET: The Ecological Infrastructure Map has been created for national purposes, and the used ecosystem types that underlie the single Ecological Infrastructure sites do not necessarily represent an ecologically functional unit (see Harris et al. (2019) for a detailed description on how the ecosystem types were delineated). Also, the models that were used to evaluate capacity, flow, demand and performance of the Ecological Infrastructure were rather simple and included several variables mainly based on indirect data. Therefore, the map may act as a guide to coastal EI in a region but might not be appropriate for any work requiring fine-scale investigations. The map and the EI evaluation still require field verification.
